Objective To investigate and compare the clinical effects of intraarticular injection of sodium hyaluronate and diprospan on knee osteoarthritis. Methods 94 patients with knee osteoarthritis were divided into two groups, the HA group and Cortieosteroid group. Each patient in the HA group was treated with intra-articular injection of sodium hyaluronate at 2.5 ml every week for 5 weeks, and each patient in the Corticosteroid group was treated with intra-articular injection of diprospan at 1ml on the first and fourth week. The clinical assessments included pain,joint effusion,and Lequesne Index. Assessments were done at baseline, at week 4, and week 12. Results 88 cases were followed up for 3 months. A significant decrease in VAS scores for pain and in Lequesne Index was found in both groups at week 4 when compared to baseline and there were no significant differences between the two groups. However,at 12 week improvement in pain score and Lequesne Index was found in favour of hyaluronic acid. In addition,diprospan seemed to have preferable short-term effect on patient with joint effusion. Conclusion Both intra-articular injection of sodium hyaluronate and diprospan provided clinically significant improvement in short-term and demonstrated that hyaluronic acid had a more long-term beneficial effect in patients with knee osteoarthritis.

Objective To investigate the prevalence of dyslipidemia and the relationship between breakfast frequency and dyslipidemia in residents over 40 years old in Yiling area of Yichang City in Hubei Province. Methods A random sampling was conducted, and 10 420 inhabitants were investigated during 2011 to 2012. Results The morbidity of dyslipidemia was 64. 0%. It was significantly higher in female than in male (65. 9% vs 60. 6%). Compared with regular breakfast eaters, non-breakfast eaters had significantly higher morbidity of higher blood low density lipoprotein-cholesterol(LDL-C) and hypertriglyceridemia(P<0. 05). The risk of elevated serum LDL-C was higher in the non-breakfast eaters group(OR=2. 382, 95%CI 1. 300-4. 367, P=0. 019) after adjusted by age, sex, smoking, drinking, etc. Conclusions Compared with regular breakfast eaters, breakfast skippers had significantly higher morbidity of dyslipidemia. Eating breakfast on daily basis may have a significant protective effect on preventing dyslipidemia.

Objective To explore the potential predominance and value of percutaneous hepatocholangiostomy (PCH) in treatment of recurrence hepatobiliary stones (RHS). Methods Seventeen cases with RHS were treated by PCH from February 2001 to October 2005, which was an improved technology of percutaneous transhepatic cholangioscopy (PTCS) and made reference to the methods of percutaneous nephrostomy (PCN). Results Seventeen cases were successfully treated. The average blood loss was 40 ml (ranging from 15 to 100 ml), and stones were removed completely in 88.2% (15/17). The average hospital stay was 14 (ranging from 10 to 59) days. No one required postoperative analgesic. No postoperative bleeding and biliary leakage were found. Conclusions PCH has significant advantages of minimal invasion, little blood loss, less pain, less complications and quick recovery in the treatment of RHS.

Objective To develop a nested PCR for the detection of early syphilis and genotyping of Treponema pallidum (TP), and to investigate the distribution of genotypes of TP in Guangzhou. Methods Specimens were consecutively collected from genital ulcers of patients with suspected chancre during 2002-2004, and were detected by dark-field microscopy and nested PCR. The acidic repeat protein (arp) gene and the T. pallidum repeat (tpr) gene family were amplified with the positive specimens above. The number of repeats presented in the arp gene and the restriction fragment length polymorphism by Mse I in the tpr gene were analyzed by electrophoresis. The strains were genotyped according to Pillay's criteria. Results Out of 62 patients with suspected chancre, 33 cases (53.2%) were positive by dark-field microscopy and 54 cases (87.1%) by nested PCR. Of 47 TP-positive specimens genotyped by arp gene, 36 (76.6%) were type 14, while of 49 cases genotyped by tpr gene 39 (79.6%) were type d. By combining genotypes of arp and tpr genes, 7 genotypes were found, including 14d (31, 66.0%), 13d (5, 10.6%), 14b (4, 8.5%), 12b (3, 6.4%), 12d (2, 4.3%), 15d(l, 2.2%) and 14i (1, 2.2%). Conclusions Nested PCR shows a high sensitivity in early detection of TP. Genotype 14d seems the predominant type of TP in Guangzhou.

ObjectiveTo investigate the effects of adult catch-up growth on insulin sensitivity and stress in rats, as well as the probable mechanism of insulin resistance. MethodsMale Sprague-Dawley rats were divided into 6 groups:caloric restriction group ( R4, caloric restriction for 4 weeks) and normal controls for 4 weeks ( NC4 ) ; catchup growth group refed with normal chow( RN4, refeeding for 4 weeks after caloric restriction for 4 weeks), catch-up growth group refed with high-fat diet( RH4, refeeding for 4 weeks after caloric restriction for 4 weeks ), normal chow (NC8) or high-fat diet( HF8 ) controls for 8 weeks. The animal model of catch-up growth was devoloped by way of refeeding after caloric restriction as scheduled. The glucose infusion rate( GIR ), 2-deoxyglucose uptake and insulinsitmulated insulin signaling in skeletal muscle during hyperinsulinemic-euglycemic clamp, plasma corticosterone, and 11β-hydroxysteroid dehydrogenase type 1 ( 11β-HSD1 ) mRNA expression level in skeletal muscle were determined.ResultsAfter caloric restriction for 4 weeks, plasma corticosterone and 1 1 β-HSD1 mRNA expression in skeletal muscle were significantly higher in R4 group compared with NC4 group( both P＜0. 05 ), but there were no differences in 2-deoxyglucose uptake and Ser473 phosphorylation of Akt in skeletal muscle between two groups. The plasma corticosterone and 11β-HSD1 mRNA expression in skeletal muscle in RN4 group were significantly higher than those in NC8 group, and were higher in RH4 group than those in NC8 and HF8 groups; while the 2-deoxyglucose uptake and insulin-stimulated Ser473 phosphorylation of Akt in skeletal muscle during the clamp in RN4 were remarkably lower than those in NC8 group, and were lower in RH4 than those in NC8, HF8, and RN4 groups (all P ＜ 0. 05 ).ConctusionsCatch-up growth rats refed with normal chow or high-fat diet are characterized by significant insulin resistance and stress in the whole body and skeletal muscle. These changes are more evident in catch-up growth rats refed with high-fat diet. The interaction of increased stress and diet might be of utmost importance in the etiology of insulin resistance in catch-up growth animals.

ObjectiveTo investigate the antidepressant effect of Sinisan （SNS） by regulating glycogen aynthase kinase-3β （GSK-3β）/tumor necrosis factor alpha-induced protein 3（A20）/CCAAT enhancer binding protein β（C/EBPβ） to inhibit the activation of microglia. MethodA total of 72 male C57/6J mice were randomly divided into the normal group， model group， fluoxetine group （5.0 mg·kg^-1）， low-dose Sinisan group （4.9 g·kg^-1）， medium-dose Sinisan group （9.8 g·kg^-1）， and high-dose Sinisan group （19.6 g·kg^-1）， with 12 mice in each group. After one week of adaptive feeding， chronic unpredictable mild stress （CUMS） was performed to establish the depression model. In the fifth week， drug treatment was conducted for four weeks. In the ninth week， behavioral tests were performed， including sucrose preference test （SPT）， open field test （OPT）， elevated plus maze （EPM） test， and forced swimming test （FST）. Western blot was used to detect the expression levels of interleukin-1β （IL-1β）， interleukin-6 （IL-6）， nitric oxide synthase （iNOS）， GSK-3β， A20， and C/EBPβ in the cortex. The expression of M1-polarized ionized calcium-binding adapter molecule 1 （Iba1） and cluster of differentiation 68 （CD68） in microglia was detected by immunofluorescence. ResultAfter eight weeks of CUMS， compared with the normal group， the mice in the model group had a significantly reduced sucrose preference rate （P<0.01）， and the activity in the central area of the OPT was significantly reduced （P<0.01）. The activity in the open arm area of the EPM test was significantly reduced （P<0.05）， and the immobility time of FST was increased （P<0.01）. The expression levels of inflammatory proteins IL-1β， IL-6， and iNOS were increased （P<0.01）， and the fluorescence co-localization index of Iba1 and CD68 was increased （P<0.05）. The protein expression levels of GSK-3β and C/EBPβ were significantly increased （P<0.05， P<0.01）. After four weeks of SNS intervention， compared with the model group， the mice in the SNS group had significantly increased sucrose preference rate （P<0.01）， significantly increased activities in the central area and the open arm area in the OPT and the EPM test （P<0.05）， and significantly reduced immobility time in the FST （P< 0.01）. The protein expression levels of IL-1β， IL-6， and iNOS were significantly decreased （P<0.05）， and the fluorescence co-localization index of Iba1 and CD68 was decreased in the high-dose SNS group （P<0.05）. The protein expression levels of GSK-3β and C/EBPβ in the medium-dose and high-dose SNS groups were significantly decreased （P<0.01）， and that of A20 was significantly increased （P<0.01）. ConclusionThe antidepressant effect of SNS is related to the regulation of GSK-3β/A20/C/EBPβ protein expression and the inhibition of M1-type activation of microglia.
