Objective: To observe the clinical efficacy of Nie-pinching the spine, puncturing Sifeng (EX-UE 10) plus Chinese herbs in treating pediatric anorexia due to dysfunction of spleen in transportation. Methods: A total of 64 kids were randomized into an observation group and a control group by the random number table method, with 32 cases in each group. Patients in both groups received Jian Pi Kai Wei (strengthening spleen and stomach) powder according to pattern differentiation of traditional Chinese medicine (TCM). In addition, patients in the observation group received Nie-pinching the spine and puncturing Sifeng (EX-UE 10). Nie-pinching the spine was applied twice a week, and puncturing Sifeng (EX-UE 10) was performed once a week, with 2 weeks counted as 1 course of treatment. After 2 courses of treatment, the body mass index (BMI), peripheral blood leptin level and the microelements Zn, Fe and Se were compared at different time points (before treatment, after the first and second courses of treatment), as well as the therapeutic efficacy and onset time. Results: After 2 courses of treatment, 31 cases in each group were evaluated. After the 1st course and the 2nd course, the BMI and serum Zn, Fe and Se levels in the observation group increased significantly (all P<0.05), the leptin level decreased substantially (both P<0.05); the BMI in the control group showed a substantial rise (P<0.05), while the Zn, Fe and Se levels slightly increased showing no statistical significance (all P>0.05), and the leptin level decreased but the difference showed no statistical significance (P>0.05). After the 1st and the 2nd courses of treatment, the BMI, serum Zn, Fe and Se levels increased more significantly (all P<0.05), and the serum leptin level decreased more significantly (both P<0.05) in the observation group than in the control group. After the 2nd course, the total effective rate and recovery rate in the observation group were both higher than those in the control group (both P<0.05), together with a quicker onset time (P<0.05). Conclusion: Nie-pinching the spine, puncturing Sifeng (EX-UE 10) plus Chinese herbs is effective for pediatric anorexia due to dysfunction of spleen in transportation. It can decrease leptin, increase Zn, Fe and Se levels, alleviate apositic symptoms and increase BMI in the kids.

Objective: To study the cytocompatibility of nanophase alumina ceramics with osteoblasts. Methods: Alumina ceramics were prepared via wet chemistry techniques. The grain size of alumina of interest in the present study was determined by scanning electron microscopy and atomic force microscopy with image analysis software. Primary osteoblast culture was established from rat calvaria. Protein content, synthesis of alkaline phosphatase(ALP) and deposition of calcium-containing mineral by osteoblasts cultured on nanophase alumina ceramics and conventional alumina ceramics for 7, 14, 21 and 28 d were respectively examined. Results: The average surface grain size of the nanophase and conventional alumina compact formulations was 60 nm and 1.80 ?m respectively.Synthesis of ALP and deposition of calcium-containing mineral were significantly greater by osteoblasts cultured on nanophase than those on conventional ceramics after 21- and 28- day culture. Conclusions: Nanophase alumina may stimulate ALP synthesis and calcium deposition of osteoblasts.

Objective To investigate the clinical efficacy of sequential plasma perfusion of low dose plasma exchange in the pa-tients with acute on chronic liver failure (ACLF).Methods The patients with HBV related ACLF in the infection department of the Affiliated Hospital of Luzhou Medical College were divided into the plasma exchange therapy group (group A,n=114)and the low dose plasma exchange sequential plasma perfusion therapy group (group B,n=144).The group A was treated only by plasma exchange of fresh frozen plasma 2 400 mL;while the group B adopted the sequential plasma perfusion of plasma exchange,with fresh frozen plasma dosage of 1 400 mL.The changes of the liver and renal function,coagulation function and electrolyte indicators were observed in the two groups.The differences in the clinical effects and adverse reactions were compared between the two groups.Results The serum levels of ALT,TBIL and INR after treatment in the two groups were significant decreased than before treatment(P<0.05);ALB and PTA were significantly improved compared with before treatment(P<0.05);there were no signif-icant differences in serum levels of CRE,K+ and Na+ between before and after treatment.The changes of various indexes before and after treatment had no statistical differences between the two groups.The total effective rate and the mortality at 24 weeks in the group B was 66.66% and 47.22% respectively,which had no statistical differences compared with the group A.The total oc-currence rate of adverse reactions in the group B was 23.75%,which was significant lower than 35.26% in the group A with statis-tical difference (P=0.011).Conclusion Sequential plasma perfusion of plasma exchange has better clinical effect and few adverse reactions for treating the patients with ACLF,which can reduce the plasma dosage significantly.

Epidemics of hand, foot and mouth disease (HFMD) have mainly been caused by Coxsackievirus A16 (CVA16) and Enterovirus A 71 (EV-A71), which circulated alternatively or together in the affected area. CVA16 has caused numerous outbreaks and epidemics in multiple countries and geographical regions, and has become an important public health problem. Based on an analysis of the complete VP1 coding region, all CVA16 strains can be divided into genotypes A, B1, and B2. Furthermore, genotype B1 can be divided into subgenotypes B1a, B1b, and B1c. After 2000, no reports of genotype B2 virus strains have been reported. All of the CVA16 strains reported in mainland China have belonged to subgenotypes B1a and B1b. Most CVA16-associated infections cause only mild symptoms; however, some CVA16 infections can lead to severe complications and even death. Vaccination is considered to be the most effective method to control the transmission and infection rate of this virus. A number of research groups are studying various vaccine types, including inactivated vaccines, genetic engineering vaccines, and DNA vaccines, amongst others. In this review, an overview is provided of the research advances in molecular epidemiology and vaccines of CVA16.

Objective To evaluate the perfectibility of colposcopy directed biopsy for the diagnosis of cervical intraepithelial(CIN)through cervial conization by loop electrosurgical excision procedure(LEEP).Methods Biopsy by colposcopy and biopsy after LEEP were analyzed retrospectively in 108 cases of cervical intraepithelial neoplasia to study the related factors of affecting the coincidence rate.Results Comparison of pathological hanges following both LEEP and colposcopy showed that 69 cases were the same,24 upgrade,and 15 downgrade.Conclusion LEEP is a kind of effective and perfect method for the specific diagnosis and treatment of CIN.Colposcopically directed biopsy has its limitations.

Objective To observe the effect of rapid reduction of physical activity on bone mass (BMC), bone mineral density (BMD)and bone metabolism in growing rats. Methods 48 male SD rats were divided into the high-intensity exercise group (T1, n=12), high tolow-intensity exercise group (T2, n=12), low-intensity exercise group (T3, n=12) and control group (Con, n=12). During the first 6 weeks,the rats in T1 and T2 group ran on treadmill with high intensity, while rats in T3 group took low-intensity treadmill exercise. 6 rats were sacrificedfrom each group at the end of 6th week. BMC, BMD of femur were measured with DEXA. Alkaline phosphatase (ALP), osteocalcin(BGP), tartrate-resistant acid phosphatase (TRACP) were detected with ELISA. The exercise intensity of T2 group was reduced rapidly to alow level as in T3 group, but remained in the other 2 groups. At the end of the second 6 weeks, the other rats were investigated again. ResultsCompared with the first measurements, ALP and BGP of the T2 group decreased significantly (P<0.05), and TRACP increased (P<0.05). There was no significant difference in BMC and BMD of femur (P>0.05). Conclusion Rapid reduction of physical activity can suppressbone formation and stimulate bone resorption of long bone among growing rats.

Protein tyrosine phosphatase (PTP) 1B is a potential target for the treatment of diabetes and obesity. We have previously identified the benzoyl sulfathiazole derivative II as a non-competitive PTP1B inhibitor with in vivo insulin sensitizing effects. Preliminary SAR study on this compound series has been carried out herein, and thirteen new compounds have been designed and synthesized. Among them, compound 10 exhibited potent inhibition against human recombinant PTP1B with the IC50 value of 3.97 micromol x L(-1), and is comparable to that of compound II.

Objective To investigate the immunogenicity and cross protective effects of two novel HCV DNA vaccines in a mice model.Methods Two self-replicating alphavirus vector-based HCV DNA vaccines, pSCK CE1E2Y and pSCK H155, were constructed based on the genes encoding the structural pro-teins (Core, E1 and E2) and structural and NS3 fusion proteins (Core, E1 , E2 and NS3) of a HCV strain isolated from a Chinese patient (genotype 1b, Hebei strain), respectively.Western blot analysis was per-formed to detect the expression of fusion antigens.The BALB/c mice were intradermally immunized with the recombinant DNA vaccines by using electroporation.The immune responses induced in mice and the cross protective effects of the recombinant DNA vaccines were evaluated.Results The DNA vaccines effectively expressed the target antigens in vitro.The antigen-specific antibody responses and specific T cell immune re-sponses were induced in mice by the immunization of replicative DNA vaccines.However, no effective cross protection was provided by either of the DNA vaccines in the surrogate challenge model based on a recombi-nant heterologous HCV (JFH1, 2a) vaccinia virus strain.Conclusion Although no effective cross protec-tion was observed, both of the two replicative DNA vaccines could induce strong humoral and cellular im-mune responses against multi-target antigens of HCV strains.This study has paved the way for further inves-tigation on the development of novel HCV vaccines.
