  • Trauma to the primary incisors may cause developmental or eruptional disturbance of the permanent successors. Two cases illustrate developmental disturbances of arrested root formation, dilaceration, and eruptional disturbances of impaction, ectopic eruption of permanent successors caused by traumatic injury to deciduous incisors. The patient of the first case suffered trauma at the age of 4 years 7 months, causing alveolar bone fracture including the maxillary right primary central and lateral incisors that were immedi-ately extracted. The second patient had trauma episodes at the age of 3 years. Avulsion of the maxillary primary right central and lateral incisors were occurred due to trauma. After such trauma, regular follow-up including radiographs is necessary to detect early any possible interference with normal eruption of permanent successors.

  • Dilaceration is a developmental disturbance in shape of teeth. It refers to an angulation, or a sharp bend or curve, in the root or crown of a formed tooth. Dilacerations are estimated to occur in 3% of all permanent dentitions. However, the etiology of dilaceration is not yet fully understood. Traumatic injury to the deciduous predecessors and ectopic development of the tooth germ are the two commonly cited causes of this anomaly. The involved tooth is usually the maxillary central incisor and it also shows high prevalence of impaction. At first, We tried to do surgical exposure with orthodontic traction but to no avail. After then surgical repositioning of the dilacerated tooth was performed. Finally, Satisfactory results were obtained at the end of treatment, with improvement in dental esthetics and functional aspects.

  • Fusion is defined as union of two separate tooth buds at some stage in their development with confluence of dentin and characterized by separate root canal and large single crown, while gemination is defined as an attempt of the single tooth bud to incompletely divide and usually result in a single root with one root canal and two completely or incompletely separated crowns. It is sometimes difficult to decide whether an abnormally large tooth is the result of fusion of a normal and a supernumerary tooth, or of gemination; use of the term 'Double tooth' may make the clinicians avoid this difficulty(Brook & Winter). Commonly there are no symptoms, but the problems associated with these anomalies include esthetics, possible loss of arch length and delayed or ectopic eruption of the permanent teeth, caries along the line of demarcation, and periodontal disease. Commonly, it dose not need to be treated in primary dentition but in case of permanent dentition, it may be requested to be treated due to esthetics and other problems. In our case, a 8 years old girl showed a Double tooth, we attained the favorable results by performing hemisection with apexification.

  • Downstream of Bid (DOBI) known as Pus10, has been identified as a modulator of TRAIL-induced cell death using RNAi library screening. The crystal structure of DOBI has revealed that it is a crescent-shaped protein containing the pseudouridine synthase catalytic domain and a THUMP-containing domain. Here, we demonstrated that DOBI is expressed in various tissues such as heart and lung, and is also expressed in various tumor cells such as HeLa and A549. Although ectopic expression of DOBI does not promote TRAIL death signaling in HeLa cells, knock-down of DOBI expression using shRNA inhibited TRAIL death signaling. DOBI is cleaved into a 54 kD cleaved DOBI during cell death, and the recombinant DOBI protein can be directly cleaved by caspases-3, or -8 in vitro. Together, these data suggest that the cleaved DOBI may acquire a new function, possibly by cooperating with tBid in the mitochondrial event of cell death caused by TRAIL.

  • The majority of lung cancers associated with hyperamylasemia are adenocarcinomas. Here we report an unusual case of a 54-year-old male patient who complained of dyspnea, anterior chest wall discomfort and facial edema for one month, presenting with a huge mediastinal mass and hyperamylasemia complicated by pericardial effusion. Histological evaluation of mediastinal mass revealed small cell carcinoma and pericardium showed nonspecific inflammation with fibrosis. The serum amylase had an electrophoretic mobility similar to that of salivary gland enzyme. There were no evidence of a salivary or pancreatic causes of hyperamylasemia. After chemotherapy, parenchymal lung lesions improved and hyperamylasemia disappeared. For the management of pericardial effusion, a pericardial window was formed. We concluded that the striking increase in serum amylase was due to the ectopic production of this enzyme by the tumor.

  • Diagnosis of heterotopic pregnancy could be delayed because of insufficient clinical symptoms. Many clinician mistook the symptoms associated with ectopic pregnancy for the symptoms of complicated normal intrauterine pregnancy. The incidence of heterotopic pregnancies has been increased because of the use of various ovulation induction and assisted reproductive technologies. We experienced a case of bilateral tubal pregnancies and intrauterine twin pregnancy in polycystic ovary syndrome woman conceived after ovulation induction by clomiphene citrate. We report this case with a brief review of the literatures.

  • Peritoneal pregnancy is an implantation in the peritoneal cavity exclusive of tubal, ovarian, or intra-ligamentary implantations. This is a rare obstetric complication with high maternal mortality and even higher perinatal mortality, and secondary type was most common. Risk factors for peritoneal pregnancy are previous history of extrauterine pregnancy or tubal surgery pelvic post-inflammatory status or presence of an intrauterine device. As it is a life-threatening condition, expectant management carries a risk of sudden life-threatening intra-abdominal bleeding and a generally poor fetal prognosis. So, when it is recognized, immediate termination of pregnancy is usually recommended. Early diagnosis of peritoneal pregnancy is difficult, but is important by their life threatening progress course to patients. Recently, we experienced primary peritoneal pregnancy which meets both the original and modified criteria. In this paper, we reported the case of early diagnosed and successfully treated peritoneal pregnancy despite of their diagnosis was incidentally.

  • Background: Dietary fat has been suggested to be the cause of various health issues. Obesity, hypertension, cardiovascular disease, diabetes, dyslipidemia, and kidney disease are known to be associated with a high-fat diet (HFD). Obesity and associated conditions, such as type 2 diabetes mellitus and nonalcoholic fatty liver disease (NAFLD), are currently a worldwide health problem. Few prospective pharmaceutical therapies that directly target NAFLD are available at present. A Traditional Chinese Medicine, ginseng-plus-Bai-Hu-Tang (GBHT), is widely used by diabetic patients to control glucose level or thirst. However, whether it has therapeutic effects on fat-induced hepatic steatosis and metabolic syndrome remains unclear. Methods: This study was conducted to examine the therapeutic effect of GBHT on fat-induced obesity, hepatic steatosis, and insulin resistance in mice. Results: GBHT protected mice against HFD-induced body weight gain, hyperlipidemia, and hyperglycemia compared with mice that were not treated. GBHT inhibited the expansion of adipose tissue and adipocyte hypertrophy. No ectopic fat deposition was found in the livers of HFD mice treated with GBHT. In addition, glucose intolerance and insulin sensitivity in HFD mice was also improved by GBHT. Conclusion: GBHT prevents changes in lipid and carbohydrate metabolism in a HFD mouse model. Our findings provide evidence for the traditional use of GBHT as therapy for the management of metabolic syndrome.

  • Ectopic expression of $14-3-3{\zeta}$ has been found in various malignancies, including lung cancer, liver cancer, head and neck squamous cell carcinoma (HNSCC), and so on. However, the effect of $14-3-3{\zeta}$ in the regulation of interactions between tumor cells and the immune system has not been previously reported. In this study, we aimed to investigate whether and how $14-3-3{\zeta}$ is implicated in tumor inflammation modulation and immune recognition evasion. In oral squamous cell carcinoma (OSCC) cell lines and cancer tissues, we found that $14-3-3{\zeta}$ is overexpressed. In OSCC cells, $14-3-3{\zeta}$ knockdown resulted in the up-regulated expression of inflammatory cytokines. In contrast, $14-3-3{\zeta}$ introduction attenuated cytokine expression in human normal keratinocytes and fibroblasts stimulated with interferon-${\gamma}$ (IFN-${\gamma}$) and lipopolysaccharide (LPS). Furthermore, supernatants from $14-3-3{\zeta}$ knockdown OSCC cells dramatically altered the response of peritoneal macrophages, dendritic cells and tumor-specific T cells. Interestingly, Stat3 was found to directly interact with $14-3-3{\zeta}$ and its disruption relieved the inhibition induced by $14-3-3{\zeta}$ in tumor inflammation. Taken together, our studies provide evidence that $14-3-3{\zeta}$ may regulate tumor inflammation and immune response through Stat3 signaling in OSCC.

  • Introduction: The aim of the current study was to describe the prevalence and treatment of mandibular first molar eruption disturbances. Methods: A total of 38 mandibular first molars(M1mn) from 36 patients(17 males and 19 females; aged 9 years 2 months?35 years 10 months) were identified from the 13,391 patients that received orthodontic treatment from 1983?2012. The subjects were classified into 3 categories based on panoramic radiographic examination: impaction due to ectopic position of the tooth germ relative to the contra-side same tooth(Group 1), impaction due to obstruction of the eruption path with cyst or calcium mass (Group 2), and primary and secondary retention due to defects in the follicle or periodontal ligament(PDL; Group 3). The treatment outcomes were evaluated into four categories: no treatment(A), orthodontic traction(B), autotransplantation(C), and extraction due to orthodontic traction failure(D). Results: The prevalence rate of M1mn eruption disturbances in this sample was 0.27%. In Groups 1 and 2, most of the impacted M1mn were erupted successfully by orthodontic traction. In Group 3, most of the retained M1mn were failed to erupt and recommended for extraction. Conclusions: Treatment prognosis was favorable on Group 1 & 2 than Group 3. After removing an element of the cause in case of Group 1 & 2, orthodontic traction or periodic observation will be recommended.
