Objective To study the correlation between expression of mannose-ligand receptor(MR) on capacitated human sperm in vitro and acrosome reaction induced by zona pellucida(ZP). Methods The swimming-up sperms were incubated in capacitating medium BWW for 6 hours at 37℃, and then treated with solubilized mouse zona pellucida(mZPS).After an hour, the percentages of spermatozoa labeled with FITC-DMA were counted and used to show the expression of MR; the percentages of acrosome-reacted sperm visualized with fluoresceinated Pisum sativum agglutinin(PSA) were recorded. Results There is no correlation between expression of MR on capacitated human sperm in vitro and acrosome reaction induced by mZPS.Conclusion Expression of MR on capacitated human sperm in vitro might not be the essence of capacitation.;

Although weight loss is beneficial for obese patients with diabetes, current medical treatment for obesity is difficult. Bariatric surgery leads to substantial and durable weight reduction.Nearly 30% of patients who undergo bariatric surgery have type 2 diabetes.For many of them, diabetes resolves following bariatric surgery (83% to 93% for bypass procedures and 55% to 84% for restrictive procedures).This review discusses the effects of various bariatric procedures on type 2 diabetes mellitus and their possible mechanisms.

Objective To study the effect of mannose receptor(MR) from human spermatozoa on sperm-egg fusion. Methods The Balb/c mouse was immunized with the purified mannose receptor(pMR) which was isolated from motile human sperm by mannose-agarose gel affinity chromatography and the anti-MR serum was harvested. Human sperm after induction of acrosome reaction was pretreated with anti-MR serum and subsequently processed in sperm penetration assay (SPA). Results The anti-MR serum can inhibit human spermatozoa from binding and penetrating zona-free golden hamster eggs with a dose-dependent reduction of Fertilization rate(FR) and Penetration index(PI).Conclusion The results indicate that MR of human sperm plays an important role in sperm-oocyte fusion.

The result regarding the application of McAbs against PwMJ-SAg in the detection of the circulating antigens(CAg) in sera from the patients (early stage and nonpulmonary type) with paragonimiasis westermani was reported in this paper. CAg in the sera from 35 patients in the early stage and 15 nonpulmonary type of patients was 100% positive by using McAb IB1 and JB4 out of 8 McAbs against PwMJ-SAg. Furthermore, these two McAbs didnot react crossly with the sera from 25 normal subjects, 15 patients with clonorchiasis, 15 patients with fasciolopsiasis, 15 patients with schistosomiasis japonica, 16 patients with Brugian filariasis or 10 patients with pulmonary tuberculosis. However, they crossly reacted with 8 samples of sera from 15 patients (53.3%) with pagumogonimiasis skrjabini. The McAb IB1 and IB4, threfore, are appropriate as the reagents to diagnose paragonimiasis westermani (early stage or nonpulmonary type). Moreover, they are also valuable, to a certain degree, to diagnose pagumogonimiasis skrjabini.The projet was supported by NNSFC Department of parasitology .Anhni Medical University, Hefei

Objective To investigate dietary fat intake and fatty acid composition in Qingdao residents.Methods Cluster random sampling method was used to select 189 adults (53 males and 136 females) between March and to July 2010.The food intake habit and the relationship between nutrient,fat,fatty acid composition and serum lipid concentrations were analyzed.Results Per capita intake of cereal was 200 g,potato 26 g,poultry meat and offal 85 g,seafood 73 g,nuts 23 g,and oils 40 g.Protein accounted for 16％ of total calorie intake,carbohydrate 48％,and fat 37％.Oils accounted for 43％ of fat intake,and nuts 11％.High fat intake was mainly contributed to intake of oils and nuts.Those with dyslipidemia showed higher nutritent intake and body mass index.ConclusionQingdao residents show higher dietary fat intake and lower long-chainω-3 (n-3) PUFAs consumption.Long-chain n-3 PUFAs may be negatively correlated with dyslipidemia.

BACKGROUND: Studies have demonstrated that exogenous basic fibroblast growth factor (bFGF) has intensive effects to promote proliferation of gingival fibroblasts (GFs) cultured in vitro and the heeling of gingival wounds. OBJECTIVE: To investigate the effects of bFGF gene transfection on the biological performance of Beagle canine GFs. DESIGN, TIME AND SETTING: An observation and comparison in vitro experiment regarding cells was accomplished in Centre of Cell Biology and Development of Fujian Medical University and Department of Comparative Medicine in Fuzhou General Hospital of Nanjing Military Area Command of Chinese PLA from April to September of 2008. MATERIALS: Four beagle dogs, male, 12 months old, weighing 10-13 kg were used in this experiment, plRES2-EGFP-bFGF plasmid containing full-length human bFGF gene cDNA was constructed and conserved by our institution. METHODS: Free gingiva of the 2nd, 3rd and 4th premolars were excised from left upper jaw of Beagle dogs, dnsed with aseptic phosphate buffer four times, then cut into pieces and digested with 2.5 g/L pancreetin for 2 hours at 37 ℃. After the cantrifugation and supernatant removal, DMEM containing 10% fetal bovine serum was added to incubate on 6-well plate with coverlips in 5% CO2 incubator at 37 ℃. Logadthrnically growing cells were digested and passaged. GFs were transfected with pIRES2-EGFP-bFGF plasmid using liposome mediated method, while vacant plasmid transfection and un-transfection group served as controls.MAIN OUTCOME MEASURES: Proliferation and apoptosis feature of the GFs were evaluated by M'rE and AOEB, respectively. The activity of alkaline phosphatase was assayed by chemical coledmetry. RESULTS: All of three groups cells entered log phrase on three days after transfection. MTT results showed that the proliferation of GFs transfected with bFGF was greater than cells transfected with vacant vector and untransfected cells (P < 0.05). AO/EB dyeing showed the apoptosis rate of GFs transfected with bFGF was reduced compared with other two groups (P < 0.05). After bGFG gene transfection, the ALP activity remained unchanged and there was no significant difference compared with untransfected cells.CONCLUSION: The transfection of bFGF gene to GFs can promote the proliferation of GFs and depress the apoptosis. No promotion is present with regard to the GFs differentiation.

Objective To observe the clinical efficacy of amitriptyline with manipulative therapy for episode tension-type headache (ETTH). Methods 62 patients were randomized into 2 groups: amitriptyline group, amitriptyline with manipulative therapy group. Numbers of days with headache(NDH) and days with medication(NDM), intensity of the headache(IH) between the two weeks before randomisation and 1～2, 3～4 weeks after randomization were recorded by participants in headache diaries. Results In the first 2 weeks after treatment, the NDH in amitriptyline group and amitriptyline with manipulative therapy group were (6.00±2.21) d and (4.19±1.70) d respectively (P<0.05), while in the second 2 weeks, they were (4.00±1.86) d and (2.16±1.21) d respectively (P<0.05). The NDM in amitriptyline group and amitriptyline with manipulative therapy group were (1.77±1.23) d and (1.32±1.22) d respectively in the first 2 weeks after treatment (P<0.05), but there was no significantly difference between the two groups in the second 2 weeks. The IH (with Visual Analog Scale) were(3.32±0.94) and (2.39±1.33)respectively (P<0.05) in the second 2 weeks. Conclusion Amitriptyline with manipulative therapy is better than amitriptyline alone in reducing the symptoms of episode tension type headache.
