Rabbit antisera against mouse LDH-C_4 were generated by immunization of rabbits with highly purified mouse lactate dehydrogenase C_4. Immunofluorescent localization of LDH-C_4 on mouse and human sperms was performed by rabbit antibodies against mouse LDH-C_4 at 1:20 dilution of antisera. Sheep anti-rabbit IgGFITC conjugates at dilution of 1:10 was used as second antibody for the detection. Human sperms were obtained from fresh semen of fertile males. Mouse sperms were prepared from epididymis fluid of mature mice. Both human and mouse sperms were thoroughly washed by PBS buffer. Sections of 4 ?m mouse testes were made and dried on the slides for the immunohistochemical localization, ?-hydroxy-n-valeric acid was used as specific substrate in incubation medium for revealing the LDH-C_4 activity. Immunofluorescent studies demonstrated that LDH-C_4 can be found on the surface of mouse and human spermatozoa. In human spermatozoa, the strong fluorescence was seen on the neck and midpiece. On mouse sperm, the antibody binding was directed toward the tail segment with little or no binding on the head or midpiece. Histochemical studies showed that the intensive formazen deposits were on the neck and midpiece of human and mouse spermatozoa, as well as the cells approximate to the lumen of mouse seminiferous tubules.

Objective To investigate the serological patterns of hepatitis B, understand the prevalence of hepatitis B infection in neonates, infants and preschool children based on hospital data in Zhejiang province and provide a basis for prevention and control of local pediatric hepatitis B infection. Methods Five serological markers were detected on electrochemiluminescence analyzer Roche E601. The results of all serological markers in children with hepatitis B from 2006 to 2010 were exported from laboratory information system and 24 892 (15 810 boys and 9 082 girls) cases were selected for further analysis according to the exclusion criterion including duplicate analysis, children older than 7 years and children living out of Zhejiang province. SPSS13.0 software and EXCEL 2003 were employed for statistical analysis in this study. Results Average HBV vaccination coverage rates among 15 413 boys and 8 840 girls were 99. 16%(98. 87% -99. 45%) and 99. 17% (98. 29% -99. 53%), respectively. Seventeen serological patterns of hepatitis B were observed, and "anti-HBs(+)alone"(64. 997%) was the dominant patterns followed by "negative" (18. 231%), "anti-HBc(+)anti-HBs(+)"(9.911%) and "anti-HBe(+)antiHBc(+) anti-HBs(+)"(4.395%), and the positive rates for other patters were 0. 004% -0. 992%. There were significant difference of detection rates for "anti-HBc(+)alone" and "anti-HBe(+)anti-HBs(+)"patterns between male and female (χ2=7.143,8.123, all P＜0.01), and there were no significant difference of detection rates for the other 15 patterns between male and female (all P ＞0.05). Ninety-four HBsAg positive cases were detected, accounting for 0.38%. Totally 19 899 anti-HBs positive cases were detected, accounting for 79.94%. Totally 16 187 cases were "anti-HBs(+) alone", accounting for 81.3%of the total anti-HBs(+) cases. The group of 1-2 years and 2 day-2 week had the highest and lowest rate for anti-HBs(+)alone respectively. The ratios in three groups with different anti-HBs levels (10-100 mIU/ml,100-1000 mIU/ml and ＞ 1000 mIU/ml) in 16 178 anti-HBs(+) children were 23. 64%, 27.66% and 13. 70%, respectively. Totally 3 904 cases with anti-HBc(+) were detected, accounting for 15.68%. The highest positivity rate and lowest positivity rate were in the group of 2-4 week and 3-4 week respectively. In total 1 565 cases with negative results, the lowest negativity rate and highest negativity rate were in the group of 9-12 month (3. 25%) and 6-7 age (36. 21%) respectively. Conclusions The dominant serological patterns of hepatitis B in local young children is "anti-HBs (+) alone" and most of the anti-HBs concentrations ranged from 100 to 1000 mIU/ml, followed by "negative". The total positive rate of HBsAg is mild. The rate of hepatitis B serological patterns in children is associated with ages but independent of gender. For interpretation of serological patterns of HBV in children below 12 months (especially in 3 months) the status of their mothers' HBV infection should also be taken into consideration.

The composition, nutritional evaluation and clinical trials of a nutritionally complete enteral preparation were presented. It was composed of glucose oligosaccharides, emulsified fat, solubilized proteins, twelve vitamins, certain minerals and trace elements. Rats were forced to negative nitrogen balance by means of protein-free diet. Body weight and serum total protein declined accordingly. When the feed was changed to this preparation in one group, and a routine one with equal nitrogen content in another, nitrogen balance was turned to positive, body weight increased, serum total protein returned to normal in both groups. The increments of nitrogen balance and body weight were, however, higher significantly in the group fed with the preparation than that with routine diet. The biological value, net protein utilization and protein efficiency ratio of the solubilized proteins in the preparation were higher than casein in the routine feed. Twenty surgical patients having the preparation as the sole source of nutrients could take around 8.37MJ(2000 kcal)a day. Nitrogen balance turned from negative to positive in an average time of 3.6 days. Body weight, serum total protein, serum albumin were all increased. Fourty patients took this as dietary supplement and the similar results were observed too. Clinical effects were excellent in all cases, especially for healing of surgical wounds and fistula. Incidence of diarrhea was 3.3%.

BACKGROUND: Mesenchymal stem cells are the stem cells that possess the capability for self-renewal and multi-directional differentiation. Umbilical cord is the tissue outside the embryos and would be fallen off after parturition. In addition, it has wide source and no ethical restriction, so it is promising to be the first choice for mesenchymal stem cells. OBJECTIVE: To detect the surface markers CD29, CD44, CD49e, CD73, CD90, CD34, CD45, and CD271 of human umbilical cord-derived mesenchymal stem cells (hUCMSCs) prior to and after cryopreservation and resuscitation. METHODS: After isolation and culture, morphology of the primary, P4 and P8 hUCMSCs was observed prior to cryopreservation and after resuscitation. Surface markers CD29, CD44, CD49e, CD73, CD90, CD34, CD45, and CD271 of primary, P4, and P8 hUCMSCs were detected through the use of flow cytometry prior to cryopreservation and after resuscitation RESULTS AND CONCLUSION: hUCMSCs prior to cryopreservation and hUCMSCs of different passages after resuscitation present the same phenotype, i.e., positive for CD29, CD44, CD49e, CD73, and CD90, and negative for CD34, CD45, CD271. These findings suggest that primary hUCMSCs do not present changes in surface markers after cryopreservation and resuscitation.

Objective To evaluate intra-and interatrial synchronization in patients with paroxysmal atrial fibrillation (PAF) by dual gate Doppler and discuss the predictive value of atrial asynchrony for detecting PAF.Methods Twenty-nine patients with PAF as AF group and 24 healthy volunteers as control group underwent echocardiography.The time interval of the onset of a'wave between mitral annular septal and lateral site was T1 by dual gate Doppler,which was used to evaluate left atrial synchronization.The time intervals from the onset of a'wave at tricuspid annular right ventricular free wall site to a'wave at tricuspid annular septal site and mitral annular lateral site were T2 and T3,which were respectively used to evaluate right atrial and interatrial synchronization.The greater time interval predicted the worse synchronization.Compared these indexes between two groups,the most valuable index was obtained and combined with left atrial volume index (LAVI) to predict PAF,its optimal values were found out by ROC curve.Results ①There were no significant differences in many other basic indexes between two groups (P ＞0.05).However,compared with control group,the ratio of early diastolic transmitral flow velocity (E) and mitral annular velocity of septal site (e'),the diameters and volume indexes of atria were significantly increased in AF group.②T1,T2 and T3 (standardized before and after) increased significantly in AF group (P ＜0.01).Standardized T1 had the largest area under curve (AUC) for detecting PAF.The AUC of standardized T1 and LAVI were 76.6％ and 84.1％.Standardized T1 ≥29.55 ms and LAVI≥ 21.60 ml/m2 were combined for detecting PAF (sensitivity 82.8 ％,specificity 79.2％,AUC 87.1％).③ Standardized T1 was positively correlated with age,left atrial systolic diameter,LAVI,RAVI and E/e'(P＜ 0.05).Conclusions Patients with PAF have worse intra-and interatrial synchronization and left atrial asynchrony can provide predictive value for detecting PAF.Dual gate Doppler is expected to be a new technique for evaluating intra-and interatrial synchronization accurately and detecting the risk of AF.

Objective To determine the ameliorative effects of Junzhi beverageⅠon neurobehavioral functions in subjects exposed to long-term sustained work.Methods Forty male students of a military institution were randomized into control group ( n=20 ) and the intervention group ( n=20 ) .All the subjects were exposed to 10-hours′high intensity mental work continuously (8∶00-18∶00).At 12∶50, the intervention group drunk a bottle of water with Junzhi beverageⅠ, but the control group drunk water of the same volume only.At 17∶00, neurobehavioral functions of all the subjects were tested by neurobehavioral core test battery (WHO-NCTB) and attention span test(AST).Results According to the results of WHO-NCBT, after 10-hours′continuous mental work,the profile of mood state in the intervention group was more stable than in the control group with lower scores in negative mood and higher scores in positive mood.Meanwhile, some of the neurobehavioral indexes were also found to be significantly improved, including shortened mean time of simple reaction and decreased error reaction rate, enhanced digit span backward, higher scores in Beton test , digit symbol test, Santa Ana practice hand and correct dot number (P<0.05).In addition, higher scores were obtained in the intervention group in AST(P<0.05).Conclusion Junzhi beverageⅠ can significantly improve the neurobehavioral function under sustained mental work conditions, which suggests that the beverage has the potential to postpone mental fatigue protect and enhance cognitive function.

Objective To study the relationship between plasma free fatty acids composition and the incidence of nonalcoholic fatty liver disease(NAFLD) .Methods By the design of case‐control study ,105 patients with NAFLD as cases and 110 healthy peo‐ple as controls were enrolled into the study .Plasma free fatty acid levels were determined by gas chromatography .Results High level of plasma palmitic acid(C16 :0)(OR=1 .769) was the risk factors of NAFLD ,while plasma levels of linoleic acid(C18 :2 n‐6) (OR=0 .855) and arachidonic acid(C20 :4 n‐6)(OR=0 .181)were negatively associated with the incidence of NAFLD .Conclusion These findings suggest that a proper ratio of diet fatty acids intake may reduce the risk of NAFLD .

BACKGROUND: At present, the researches on steroid-induced avascular necrosis of the femoral head are mostly concentrated on the treatment of formed necrosis. And there are fewer reports on how to prevent the ostoenecrosis of the femoral head in the course of steroid therapy.OBJECTIVE: To observe the effect of preventive medication on femoral head structure and blood flow in steroid-induced osteonecrosis.DESIGN: Randomized controlled experiment.SETTING: Department of Pharmacology, Department of Anatomy, Medical College of Shaoguan University; Department of Nuclear Medicine, Guangdong Province Yuebei People's Hospital.MATERIALS: Thirty adult New Zealand rabbits of either sex, whose body mass was (2.5±0.5) kg.METHODS: The experiment was carried out in the Central Laboratory,Medical College of Shaoguan University, the Department of Electron Microscope, the Northern Campus of Guangzhou, Sun Yat-sen University, and the Department of Nuclear Medicine, Guangdong Province Yuebei People's Hospital from April to July 2005. ①Thirty rabbits were divided randomly into 3 groups with 10 rabbits in each group: control group with intramuscular injection of 1 mL/kg normal saline twice a week and meanwhile, intragastric administration of normal saline(10 mL/d), steroid group with intramuscular injection of dexamethasone sodium phosphate(1 mL/kg) twice a week and meanwhile, intragastric administration of normal saline(10 mL/d),treatment group with intramuscular injection of dexamethasone sodium phosphate(1 mL/kg) twice a week and meanwhile, intragastric administration ofXuesaitong(25 mg/kg), Zhibituo(350 mg/kg) and alendronate(5 mg/kg)daily for 8 weeks. ②After 1 week of drug withdrawal, the blood flow of femoral head was measured in all the rabbits with radioactive microsphere technique, and the histological changes were observed under light microscope and electron microscope.MAIN OUTCOME MEASURES: ①Blood flow of the femoral head in each group.②Histological and morphological changes, and ultrastructure of the femoral head cartilage in each group.RESULTS: ①The blood flow in the treatment group was more than that in the steroid group[(0.261±0.042), (0.197±0.053) mL/(min·g), q=6.10,P ＜ 0.01]. Compared with the control group[(0.243±0.039) mL/(min ·g)],the difference was not significant. ②The number of empty bone lacunae in the treatment group was fewer significantly than that in the steroid group [(15.22±5.49), (24.78±7.87) pieces, q=6.35, P ＜ 0.01]. However, there was no difference between the treatment group and control gruop [(10.38±3.78)pieces].③In the treatment group, the bone cells were normal, the endoplasmic reticula were abundant and the cellular nuclei were of normal shape.In the steroid group, the bone cells contracted in volume, the pyknosis occurred, the chromatin gathered to the edge and the bone lacuna enlarged.CONCLUSION: While using steroid hormone for long, using Xuesaitong,Zhibituo and alendronate may elevate the blood flow of femoral head, improve the tissue structure of bone and prevent or lighten steroid-induced necrosis of femoral head.
