OBJECTIVEThis study aims to investigate the prevalence and distribution of teeth number and morphology abnormalities in Chinese pediatric patients' permanent teeth at the mixed dentition stage by performing panoramic radiographs analysis.

METHODSA total of 4 347 panoramic radiographs of pediatric patients aged 5 years to 15 years who were admitted to the hospitals from September 2011 to September 2013 were reviewed. The presence of teeth number and morphology abnormalities were recorded as follows: congenitally absent teeth, supernumerary teeth, odontoma, microdontia, fused teeth, dilaceations, and cusp deformity. SPSS 16.0 software was used for statistical analysis.

RESULTSThe prevalence of teeth number and morphology abnormalities in pediatric patients' permanent teeth was 31.79% (1,382/4,347). The prevalence was higher in males. Significant difference between the genders was observed (P < 0.05). Tooth agenesis, the most frequent dental anomaly (15.00%, 652/4,347), was considerably common in females; supernumerary teeth (12.61%, 548/4,347) followed, which was significantly common in males. Both differences were statistically significant (P < 0.05). The levels of prevalence of both microdontia and dilacerations were 4.00% (174/4,347) and 2.16% (94/4,347). The prevalence of cusp deformity, odontoma, and fused teeth were relatively low at 0.74% (32/4,347), 0.51% (22/4,347), and 0.39% (17/4,347), respectively.

CONCLUSIONThe prevalence of teeth number and morphology abnormalities in children's permanent teeth at the mixed dentition stage is apparently high. Tooth agenesis and supernumerary teeth are the most frequent. Panoramic radiograph is an efficient method for the early diagnosis of teeth number and morphology abnormalities. This method can assist pediatric dentists to formulate treatment plans for children at the appropriate time.

Clinical data of 28 cases of childhood bronchiolitis obliterans treated from September 2008 to November 2010 were retrospectively analysis.Pulmonary high-resolution CT (HRCT) showed that bronchial wall thicken was seen in all 28 patients,the mosaic pattern in 26 cases,patchy shadows in 18 cases,bronchiectasis with typical signet ring sign in 2 cases,atelectasis in 2 cases without pleural effusion.Pulmonary function tests and flexible bronchofiberscopy were performed in 6 cases,which showed the inflammation in bronchial tunica intima and obstruction of small airway.Blood routine,blood sedimentation,c-reaction protein,TORCH,hepatic function,renal function and immune function were normal.Patients received comprehensive treatment with methylprednisolone,clarithromycin and montelukast.The clinical conditions of 28 cases were improved with varying degrees after treatment and no significant side effects were observed.

Objective:To investigate the incidence and distribution of malignant tumor in Uygur People and provide a theoretical basis for epidemiological surveys. Methods:A retrospective study was conducted from November 2007 to October 2012 on inpatients with malignant tumors at The First People′s Hospital of Kashgar Prefecture. The top 10 kinds of malignant tumor were found in Uygur People and Han People. Results:A total of 7578 patients were registered, including 6840 (about 90.26%) Uygur People, 628 (nearly 8.29%) Han People, and 110 (about 1.45%) from other minority groups. The top 10 kinds of malignant tumor for Uygur People were gastric cancer, esophageal cancer, leukemia, cervical cancer, malignant lymphoma, primary hepatic carcinoma, breast cancer, head and neck cancer, lung cancer, and colorectal cancers. Meanwhile, the order for Han People were lung cancer, colorectal cancer, breast, gastric, primary hepatic, head and neck, leukemia, cervical, esophageal cancer, and pancreatic cancer. Conclusion:A different epidemic character of malignant tumor existed between Uygur People and Han People in Kashga, Xinjiang.

Interleukin-6(IL-6)is associated with cancer staging, survival, apoptosis and the sensitivity to chemotherapeutic drugs, and it is overexpressed in the cancer tissue and serum of cancer patient.IL-6 Can regulate proliferation and differentiation of cancer cells through IL-6/STAT3 signaling pathway. Therefore, blocking IL-6/STAT3 signaling pathway has potential therapeutic implications for cancer.

BACKGROUND: The pain caused by osteoporosis and osteoporotic fracture is usually treated with non-steroidal anti-inflammatory drugs (NSAIDs) in clinic, which has been reported that dysfunction of liver and kidney will follow the use, but what has happened in the tissue of liver and kidney is not reported. OBJECTIVE: To study the effect of NSAIDs on the tissue of liver and kidney in osteoporotic fracture rats. DESIGN, TIME AND SETTING: Randomized controlled animal experiment. The experiment was completed in the Animal Experiment Center in Shanghai University of Traditional Chinese Medicine from August 2007 to February 2008.MATERIALS: A total of 24 female SD rats, 8-month-old, weighing 300-320 g, were randomly divided into 3 groups, saline group,diclofenac sodium (fracture before medicine) group and diclofenac sodium (fracture after medicine) group, with 8 rats in each group.METHODS: The rats were housed for 3 months after ovariectomized to establish osteoporosis models. Rats in the saline group and diclofenac sodium (fracture before medicine) group were administrated saline and diclofenac sodium after transverse osteotomy at the middle shaft of bilateral femur respectively; in the diclofenac sodium (fracture after medicine) group were femur.MAIN OUTCOME MEASURES: The histological observation of liver and kidney was performed at weeks 2, 3, 4 and 6 after fracture.RESULTS: In the diclofenac sodium (fracture before medicine) group, diclofenec sodium caused the inflammatory response at glomeruli, which exhibited expansion of tubular lumen, edema of epithelial cells, disappeared cell nuclei, degeneration and necrosis of renal tubule, cell debris and drugs crystals accumulated in the tubular lumen, congestion and inflammatory cell infiltration of renal interstitium. Administrating diclofenac sodium may cause the inflammatory response at portal area, indistinct structure of hepatic Iobule, hepatic cells edema, steatosis and necrosis. Administrating diclofenac sodium before osteoporotic fracture also resulted in tissue lesions in kidney and liver, the damage would continue about 3 weeks.CONCLUSION: The diclofenac sodium cause histological lesions of kidney and liver in osteoporotic rats, especially in kidney. The histological lesions of kidney and liver are inreversible after administrating diclofenac sodium for a long time.
