Objective To explore the relationship between quality of life and sub-health state of Guangdong urban dwellers.Methods A total of 2 200 urban dwellers were investigated using SF-36 and Sub-Heahh Measurement Scale Version 1.0(SHMS V1.0).Results As for the scores in PCS,MCS,psychosocial symptom,cognitive function,social adaptability,those of man urban dwellers (respectively (78.89± 15.25),(73.15 ± 15.26),(63.73± 18.82),(62.13± 19.34),(68.04± 17.90)) were higher than those of woman dwellers (respectively(76.98± 14.20),(71.76± 14.72),(60.53± 18.28),(57.00± 17.89),(65.73± 17.07)).The difference was statistically significant (P＜0.05).Bivariate correlation analysis showed that the PCS and MCS of quality of life were positively related with all dimensions of sub-health (P＜0.001).Canonical correlation analysis indicated that vitality,social adaptability,psychosocial symptom and positive emotion were the main factors of sub-health status,and MCS was of quality of life.Conclusion Sub-health state of Guangdong urban dwellers is positively related with quality of life,and the more serious sub-health state is,the worse quality of life is.Therefore,intervention of subhealth and quality of life should be targeted to be strengthened according to the investigation.

Objective To investigate the etiology of iatrogenic bile duct injury and experience in its diagnosis and treatment. Methods A retrospective study was conducted on the clinical data of 86 patients with iatrogenic trauma in the bile duct. Results These 86 cases have received a total of 156 sessions of surgical procedures, including 2 explorations in 66 cases,3 explorations in 6 cases. Lateral bile duct injury in 22 cases was treated by suture repair and T tube stent. Eight cases suffering from iatrogenic transection of the common bile duct were retrieved by cholangiojejunostomy and T tube stent. Nine cases with inadvertent CBD ligature were managed by a lysis and T tube stent. Roux en Y cholangiojejunostomy was adopted in 77 cases. Sixty cases were followed up for 1～10 years, with good result in 90% of the cases. Conclusions Most CBD iatrogenic injury cases were encountered as a result of cholecystectomy.Roux en Y cholangiojejunostomy is the choice of therapy.

Along with the development of computer techniques and the dissemination of Internet,many investigators of microorganisms already can acquire a lot of knowledge of many fields on microbe via Internet,extremely including the whole genome of a certain microbe. This was considered unimaginable in the past.Rapid collection of information also to a great extent expands the researching ranges and researching ability of microbial researcher,and at one time,the highly developed Internet provides a unprecedented opportunity for intercommunication of information?share of resources and international cooperations of microbiology.

Inflammatory bowel disease (IBD) is a chronic, repeated intestinal inflammatory disease. Clinically commonly used therapeutic drugs have some disadvantages, such as poor efficacy and many adverse reactions after long-term application. Although new biological therapies such as anti-tumor necrosis factor agents, overcome common adverse reactions, also have problems such as high price, difficult storage, drug resistance and recurrence after application. In recent years, many new therapeutic methods for inflammatory bowel disease have emerged, for example, modulators that inhibit lymphocyte migration (integrin inhibitors and sphingosine 1-phosphate receptor agonists) have been introduced into the clinical treatment of inflammatory bowel disease, inflammatory cytokine inhibitors (interleukin-23 inhibitors, Janus kinase inhibitors, phosphodiesterase inhibitors, etc.) and inhibitors targeting fibrosis and intestinal tissue degradation and remodeling (matrix metalloproteinase inhibitors) are also being evaluated in clinical trials of IBD. Based on the mechanisms of action, this paper intends to outline the current mainstream IBD therapies and some emerging drugs, and briefly introduce their targets to provide reference for IBD drug design and development.

BACKGROUND:Overproduction of thyroid hormones is shown to increase the activities of osteoblasts and osteoclasts, stimulating bone resorption and transformation. Inadequate compensation of increased bone resorption by bone transformation results in an increased loss of bone mass.
OBJECTIVE:To investigate the effects of hyperthyroidism on the density of the alveolar bone.
METHODS:Twenty-four New Zealand rabbits were equal y randomized into hyperthyroidism group and control group. Rabbits in the hyperthyroidism group or control group were daily injected intraperitoneal y with 50μg/kg levothyrocine diluted in physiological saline solution or equal volume of physiological saline. At 8 weeks after treatment, serum levels of thyroid hormones (FT3 and FT4), alkaline phosphatase, magnesium and calcium, phosphorus were determined;meanwhile, the bone densities of the lumbar vertebra, mandible, bilateral distal femur were determined by dual energy X-ray absorptiometry and the correlation analysis was performed.
RESULTS AND CONCLUSION:At 8 weeks after treatment, serum levels of FT3, FT4, alkaline phosphatase calcium, phosphorus, and magnesium in the hyperthyroidism group were significantly increased (P<0.01), while the bone densities of the lumbar vertebra, mandible, bilateral distal femur were significantly decreased (P<0.05), compared with the control group. Bone density of the mandible was positively correlated with the bone density the lumbar vertebra and bilateral distal femur. These findings suggest that the changes in FT3 and FT4 are sufficient for the diagnosis of hyperthyroidism. Hyperthyroidism results in the decreased density of the alveolar bone, indicating the occurrence of osteoporosis.

Objective To evaluate clinical remission in patients with small bowel Crohn's disease (SBCD) who have received infliximab(IFX) therapy and to evaluate capsule endoscopy combined with ileocolonoscopy for mucosal healing at 14th week of IFX therapy.Methods Clinical data of 23 SBCD patients who received IFX were retrospectively analyzed.Laboratory indices [routine blood tests,C-reactive protein (CRP)and albumin],Crohn's disease activity index (CDAI),Lewis score (LS),Crohn's disease simplified endoscopic score (SES-CD),side effects and complications were compared before IFX treatment and at 14th week of IFX therapy.Results In 23 SBCD patients,both CDAI and CRP levels significantly decreased (P＜0.01) while body mass index (BMI) and albumin levels increased at 14th week (P＜0.05),compared with those before treatment.The clinical remission rate at 14th week was 91.3％ (21/23).There were 8/23 (34.8％)SBCD patients achieving mucosal healing in small bowel,12/21 (57.1％) in terminal ileum and colon,and 7/21 (33.3％) in both small bowel and colon.Twelve patients achieved both clinical remission and biochemical remission at 14th week and all of them achieved mucosal healing in both terminal ileum and colon (SES-CD ≤ 2).However,there were 5 (41.7％) of them still with small bowel inflammation (LS＞ 135).Conclusion IFX plays a role in promoting clinical remission and mucosal healing in SBCD patients.Mucosal healing of CD patients in terminal ileum and other parts of small intestine are not synchronized.For CD patients with small bowel and colon involved,the evaluation of the whole gastrointestinal tract by capsule endoscopy combined with ileocolonoscopy is recommended on condition that they have no intestinal obstruction or severe stricture.
