Objectives: The purpose of this meta-analysis was to evaluate the effects of berberine on non-alcoholic fatty liver disease (NAFLD) through a systematic review and meta-analysis. Methods: We searched seven electronic databases for studies through October 2022. All randomized controlled trials (RTCs) of berberine were included. Data extraction and risk of bias assessments were performed by two independent reviewers. The RevMan 5.4.1 program was used for meta-analysis. Results: A total of 279 relevant studies were identified, and 6 eligible RCTs were included to study the efficacy berberine on NAFLD. The six selected trials are studies on the effect between berberine and conventional treatment combined treatment versus conventional treatment. Liver function tests, blood lipid levels, and blood glucose levels were assessed. Combination treatment with berberine, ursodeoxycholate acid, metformin, and monascus purpureus showed statistically significant improvements in liver function levels, blood lipid levels, and blood glucose levels compared to conventional treatment alone. However, there was no significant efficacy of berberine combination dietary, exercise than control group on NAFLD. The meta-analysis results of examining 4 RCTs comparing the therapeutic efficacy of berberine showed statistically significant improvement in the liver function test, blood lipids levels, blood glucose levels. Conclusions: This study suggests that berberine has positive efficacy on blood lipids, blood glucose liver function, fatty liver condition of NAFLD. However, the level of evidence is low because of small effect size,so further investigation is needed.

Objective: To document the signal characteristics of intracerebral hemorrhage (ICH) at evolving stages on diffusion-weighted images (DWI) by comparison with conventional MR images. Materials and Methods: In our retrospective study, 38 patients with ICH underwent a set of imaging sequences that included DWI, T1-and T2-weighted imaging, and fluid-attenuated inversion recovery (FLAIR). In 33 and 10 patients, respectively, conventional and echo-planar T2^* gradient-echo images were also obtained. According to the time interval between symptom onset and initial MRI, five stages were categorized: hyperacute (n=6); acute (n=7); early subacute (n=7); late subacute (n=10); and chronic (n=8). We investigated the signal intensity and apparent diffusion coefficient (ADC) of ICH and compared the signal intensities of hematomas at DWI and on conventional MR images. Results: DWI showed that hematomas were hyperintense at the hyperacute and late subacute stages, and hypointense at the acute, early subacute and chronic stages. Invariably, focal hypointensity was observed within a hyperacute hematoma. At the hyperacute, acute and early subacute stages, hyperintense rims that corresponded with edema surrounding the hematoma were present. The mean ADC ratio was 0.73 at the hyperacute stage, 0.72 at the acute stage, 0.70 at the early subacute stage, 0.72 at the late subacute stage, and 2.56 at the chronic stage. Conclusion: DWI showed that the signal intensity of an ICH may be related to both its ADC value and the magnetic susceptibility effect. In patients with acute stroke, an understanding of the characteristic features of ICH seen at DWI can be helpful in both the characterization of intracranial hemorrhagic lesions and the differentiation of hemorrhage from ischemia.

Objectives This study aimed to analyze the research trends in clinical studies on the traditional Korean medicine used for cancer treatment between 2011 and 2020. Methods We searched 7 Korean web databases (Research Information Sharing Service [RISS], Oriental Medicine Advanced Searching Integrated System [OASIS], Koreanstudies Information Service System [KISS], Korean Medical database [KMBASE], DBpia, Korea Institute of Science and Technology Information [KISTI], and KoreaMed) and classified collected papers dated between 2011 and 2020 by the year of publication, publication journal, study design, type of cancer affecting the patients, interventions used, evaluation system used, and combination with conventional medicine. Results A total of 167 papers were collected. More than 10 papers were published annually. The papers were mainly published in the Journal of Korean Traditional Oncology (28.7%). The predominant type of the study was case study (67.7%). The main type of cancer was breast cancer, affecting 262 patients. Most of the studies reported using multiple traditional Korean medicine treatments (55.1%). Eighty-nine studies reported using clinical laboratory tests for evaluation. Most of the patients took conventional medicine simultaneously (608 patients). Conclusions Research related to Korean medicine for cancer patients is at a rudimentary level. Therefore, for further clarity, high evidence-based researches, including randomized controlled trials and cohort studies, should be conducted.

This study was performed to compare manual liquid-based preparation with conventional Papanicolaou tests in view of the cytologic diagnoses and specimen adequacy. The specimens of 5,979 women from 33 local clinics and 1 general hospital were prepared by both manual liquid-based preparation and conventional Papanicolaou test. The cytologic diagnoses and specimen adequacy were evaluated in Department of Fathology in Kyoungpook National University School of Medicine. A conventional Papanicolaou test was always prepared first, after that residual material on the sampling device was rinsed into a liquid preservative, and then thin-layer slides were prepared using manual method of liquid-based cervicovaginal cytology. Conventional and liquid-based slides were read independently, and cytologic diagnoses and specimen adequacy were classified using the Bethesda System. Of the cases, 5,763 (96.3%,) had the same interpretation, and there was no significant diagnostic difference in 5,853 (97.8%) cases. When evaluating cases with more than one diagnostic class difference, the manual liquid-based preparation demonstrated a statistically significant overall improvement (2.1%) in the detection of squamous intraepithelial lesion and invasive cancer. Using manual method of liquid-based preparation, there was 14.1%, reduction in unsatisfactory slides through excellent cellular presentation. In conclusion, the manual liquid-based preparation produces standardized quality, superior sensitivity and improved adequacy as compared to the conventional method.

Background: The aims of present study were (1) to evaluate new bone formation among the 4-hexylresorcinol (4HR)-incorporated silk fabric membrane (SFM), conventional SFM, and uncovered control groups and (2) to compare the amount of residual membrane between the 4HR-incorporated SFM and conventional SFM in a rabbit parietal defect model. Methods: Nine New Zealand white rabbits were used for this animal study. After the formation of a bilateral parietal bone defect (diameter 8.0 mm), either 4HR-incorporated SFM or conventional SFM was grafted into the defect. The defect in the control was left uncovered. New bone formation and the amount of residual membrane were evaluated by histomorphometry at 8 weeks after the operation. Results: The total amount of new bone was $37.84{\pm}8.30%$ in the control, $56.64{\pm}15.74%$ in the 4HR-incorporated SFM group, and $53.35{\pm}10.52%$ in the conventional SFM group 8 weeks after the operation. The differences were significant between the control and 4HR-incorporated SFM group (P = 0.016) and between the control and conventional SFM group (P = 0.040). The residual membrane was $75.08{\pm}10.52%$ in the 4HR-incorporated SFM group and $92.23{\pm}5.46%$ in the conventional SFM group 8 weeks after the operation. The difference was significant (P = 0.039). Conclusions: The 4HR-incorporated SFM and conventional SFM groups showed more bone regeneration than the control group. The incorporated 4HR accelerated the partial degradation of the silk fabric membrane in a rabbit parietal defect model 8 weeks after the operation.

The aim of this study was to examine normal bronchi in dogs by using virtual bronchoscopy (VB) and to evaluate the utility of VB in clinical practice. The bronchi of six dogs without tracheobronchial disease were visualized by VB. Airways from the tracheal bifurcation to the lobar bronchi were well visualized in all dogs. Segmental and subsegmental bronchi were also well identified, but the degree and number of those varied with dog size. The mean numbers of segmental and subsegmental bronchi identified in the six dogs were 41.83 and 50.17, respectively, whereas, the mean numbers in medium- and large-sized dogs were 55.00 and 82.67, respectively, and in small-sized dogs, the means were 28.67 and 17.67, respectively. Although there were size-dependent differences in VB visualization of the bronchi, it was possible to identify peripheral airways to the subsegmental bronchi level, which can rarely be accomplished via conventional bronchoscopy. VB is the noninvasive method that can be used to examine bronchial anatomy, and our results suggest that VB can be useful for evaluating bronchi, including segmental and subsegmental ones that cannot be examined routinely by conventional bronchoscopy. Thus, VB has potential as an alternative to conventional bronchoscopy in the examination of bronchi in dogs.

Statement of problem. Various double crown systems have been used with removable partial dentures in the clinical field. Although retentive force between inner and outer crown are affected by several factors, differences between the retentive forces of different double crown system types are expected. Purpose. The purpose of this study was to evaluate the initial retentive force of outer crowns fabricated by the conventional casting technique in conus and hybrid double crowns. Material and methods. Ten double crowns were fabricated. The groups were as follows. Group 1, double crowns of hybrid inner and outer crowns using the conventional casting method; Group 2, double crowns of conus inner and outer crowns using the conventional casting method. Tensile strengths of double crowns when the inner and outer crowns were separated on a universal testing machine were measured. These values of retentive force were then statistically analyzed using the Kruskal-Wallis test. Results. Retentive force in group 2 was significantly higher than that in group 1(p<.05). Conclusion. The initial retentive forces of double crowns were affected by the types of the double crown system.

Objective : This study is to evaluate the efficacy of intracytoplasmic sperm injection (ICSI) for previous fertilization failure with conventional in vitro fetrtilization (IVF), compared with ICSI for male factor. Method: The author analyzed the 3 years of clinical experience with ICSI retrospectively, between the conventional IVF failure group (IVF failure) and male factor group (male factor). Surgically retrieved epididymal or testicular spermatozoa for ICSI were excluded. The IVF failure group was 13 cycles of 6 patients and male factor group was 30 cycles of 15 patients. Results: The fertilization rates of the IVF failure group and male factor group were 63% and 66% respectively (p=0.635). The clinical pregnancy rates of the both group were 23.1% and 26.7% (p=0.804), and that of live birth rates were 15.4% and 13.3% (p=0.858). There were no significant difference between the two groups. Conclusion: The author concluded that ICSI can overcome previous fertilization failure, with the same fertilization and clinical pregnancy rates seen in patients with male factor.
