Objective To observe the influence of weight - lost therapy on obese children with impaired glucose tolerance( IGT), insulin resistance. Methods Fasting,post- prandail 2 hours blood glucose and insulin were measured in 14 obese children (age 8 - 15 years) with IGT before and after two - month weight - lost iherapy. Glucose were measured with enzymeoxidize assay, and insulin were measured with radio-immunity assay(RIA). Results Among 14 obese children with IGT, after two-month weight - lost the-rapy, there were 9 children becoming normal OGTT. There were significantly lower in the concentration of fasting insulin and post - prandail 2 hours blood insulin and glucose[(14.23?2.35) mIU/L,(47.20?10.26) mIU/L,(5.36?0.91) mmol/L] than before weight -lost therapy[ (32.54?7. 13) mIU/L,( 164.53?33.60) mIU/L, (8.75?1.09) mmol/L](P

Nitric oxide (NO), which is involved in the regulation of the cardiovascular system, nervous system, immune system, reproductive system, digestive system and other physiological activities, is an important biological substance with activity. Under normal physiological conditions, neuronal nitric oxide synthase (nNOS) can precisely regulate the nervous system NO production, release, diffusion and inactivation processes. But an excess of NO associates with the development of cerebral ischemia, Alzheimer's and Parkinson's psychosis nervous system diseases, while inhibition of nNOS activity can regulate the content of NO in vivo, and produce a therapeutic effect on some of the nervous system diseases. This review mainly describes the structure and regulation of nNOS and recent developments of small molecule inhibitors of nNOS.

Terminal restriction fragment length polymorphism(T-RFLP) is a resent molecular approach that can assess subtle genetic differences between strains as well as provide insight into the structure and function of microbial communities. This method overcomes the confinement of conventional culture-dependent methods and has both high sensitivity and throughput making it ideal for comparative analyses. Though there is still no application in our country, more and more investigators are highlighting it. In this article, the fundamental principle of this technique is introduced. The recent application and the development of this technique are also summed up .

Objective To investigate the therapy for small and short penis in simple obesity children.Methods Sixty simple obesity children with short and small penis were randomly divided into 2 groups(experiment group 30 cases and control group 30 cases).The experiment group received comprehensive treatment(consisting of massage of traditional Chinese medicine,behavior modification,dietetic and sport adjustment) to lose weight and treated by short and small penis healing apparatus.The control obesity children were given conducted behavior,dietetic and sport adjustment,and treated by short and small penis healing apparatus.Results After treatment,weight of 30 cases in the experiment group decreased,with a decrease of(7.75?3.50) kg.Body mass index(BMI) decreased from(31.10?3.88) before treatment to(27.82?3.49),and BMI before and after treatment changed significantly(t=12.68 P

Objective To explore incidence of child obesity in Zhengzhou area and intervention measures.Methods In 2001, spot check was conducted on 5688 cases of high and primary school students ,including 2848 boys and 2840 girls at the age of 7-18.Child obesity was diagnosed by meeting reference BMI value published by Cole et al,conducted comprehensive treatment consisting of massage intervention along channel of traditional Chinese medicine, behavior modification, dietetic and sport adjustment for 22 cases of simple obesity children (7-15 years old, 18 boys, 4 girls) selected for one month, and follow-up survey 6 months after treatment.Results Five thousands,six hundreds and eighty-eight high and primary school students investigated had an overweight incidence of 15.4%, an obesity incidence of 3.2%,boys' overweight incidence and obesity incidence(19.2%,4.6%) were remarkably higher than those of girls (11.5%,1.7% P<0.001). Overweight incidence of various age groups evidently differed(χ2=42.88 P<0.001) with the group of 8-15 years old children as popular. Incidence of various age groups also differed(χ2=21.28 P<0.05) with 7-10 years old and 14-15 years old children as popular. After one-month treatment, weight of all the 22 cases of fat children decreased from (76.45±19.87) kg upon hospitalized to (69.06±17.98) kg with a decrease of (7.43±2.58)kg, BMI value decreased from (31.05±3.96) before treatment to (27.72±3.54).Weight and BMI value before and after treatment differed evidently (t=13.6,12.88 P<0.01), and weight and BMI value decrease were remarkably related with those upon hospitalized (r=0.77 P<0.01;r=0.49 P<0.05).Conclusions Incidence of child obesity has been increasing in recent years, comprehensive treatment consisting of massage intervention along channel of traditional Chinese medicine, behavior modification, dietetic and sport adjustment have good curative effect and are comfortable, well received by children and suitable to promote and apply.

AIM: To evaluate the diagnostic accuracy of macular ganglion cell - inner plexiform layer ( GCIPL ) measurements using high- definition optical coherence tomography ( Cirrus HD - OCT ) ganglion cell analysis algorithm for detecting early and moderate to severe glaucoma.
METHODS:Twenty normal control persons, 26 patients with early glaucoma and 29 patients with moderate to severe glaucoma were enrolled in this study. Macular GCIPL, optic nerve head ( ONH ) parameters and peripapillary retinal nerve fiber layer ( RNFL ) thickness were measured in each subject. Then all measured results of each parameter were calculated using SPSS17. 0. Areas under the receiver operating characteristic curves ( AUC) of each parameter were calculated to compare the diagnostic accuracy for detecting early and moderate to severe glaucoma.
RESULTS: For detecting early glaucoma, AUC of average RNFL and seven clock value of RNFL were the biggest ( 0. 871 and 0. 896 respectively ), the AUC of parameters in GCIPL were also significant, among them,
the average GCIPL showed bigger AUC(0. 847) than the minimum GCIPL (0. 812). For diagnosing moderate to severe glaucoma, the AUC of rim area was 0. 992, which was bigger than that of average RNFL ( 0. 991 ). The minimum GCIPL showed bigger AUC ( 0. 983 ) than the average GCIPL (0. 967). For early glaucoma diagnosis, the sensitivity of average RNFL was the highest (76. 9%), while the average GCIPL has the highest specificity (93. 5%).
CONCLUSION: AS a new diagnostic parameter for detecting glaucoma, GCIPL shows similar diagnostic potential compared with RNFL. For early glaucoma diagnosis, average RNFL is the most important parameter, while screening early glaucoma, average GCIPL should be paid more attention.

Objective. This study is to investigate the functional mimicry by using anti-idiotypic antibodies of enzymes.Results.Eight hybridomas strains secreting anti-idiotypic antibodies were selected and characterized. It was shown that two of eight anti-idiotypic antibodies secreted by two hybridomas(1A10C9 and 2A11 C1B3) could mimic HEL catalytic activity to lyse Micrococcus lysodeikticus and that the catalytic effect of mixed anti-idiotypic antibodies of 1A10C9 and 2A11C1B3 was stronger than that of one of them, but less than HEL.Conclusion. The results demonstrated that the anti-idiotypic antibodies that could mimic enzyme activity existed in the idiotype network during anti-enzymatic immune response.

OBJECTIVETo evaluate the effect of bridged free latissimus dorsi musculo-cutaneous flap on repairing of soft tissue defect in the lower extremity.

METHODSSeven patients with extensive soft tissue defects in the lower extremities were enrolled in the clinical investigation. The defects were all repaired with bridged free latissimus dorsi musculo-cutaneous flaps. The condition of the blood vessels in the flaps and the healthy extremities was examined with ultrasound Doppler before the operation to assure the blood circulation of grafted flap. After debridement, the flap was designed in accordance with the size and the depth of the wound. Then the transplantation of the flaps were done. The operative indication and points for attention were summarized thereafter.

RESULTSAll the 7 flaps survived. All patients recovered well with satisfactory function and external appearance, except flap reduction was done in 2 patients due to undue thickness of the flaps. Indications for operation: (1) Patients with anterior or posterior tibial artery injury in the injured lower extremity in which arterial transplantation was not possible to allow the free transplantation of a skin flap. (2) The injury was extensive and deep, with the injurious condition of the blood vessels indeterminable and no healthy artery could be found for anastomosis with a donor artery. (3) No vascular injury could be identified in the contralateral healthy extremity. Points for attention included that the blood supply of the flap to be transferred should be adequate, and the survival of the flap after division of the pedicle should be assured. The length of the flap to be transferred should be longer by 10% than the distance between the site of transplantation in the lower extremities and the donor area; and the donor area should be larger by 20% than the recipient area. The skin area of the flap to be transferred should be broad enough avoid tension so that there would be no pressure on the blood vessels. Pay attention to the blood supply of the flap after operation, and the recipient limb should be properly immobilized.

CONCLUSIONThe repair of extensive soft tissue defect in the lower extremity with bridged free latissimus dorsi musculo-cutaneous flap could be satisfactory. Proper wound management, broad flap, stable immobilization were the pivotal points for the success of the operation.

Introduction：Neonatal tetanus is a major cause of neonatal mortality in many developing countries and remains a major public health problem. This study aimed to determine risk factors associated with neonatal tetanus in Wenzhou, China.Methodology：Medical records of neonatal tetanus cases from 17 hospitals over a 13-year period (2000–2012) were reviewed for potential risk factors. Controls were selected from neonates with diseases other than tetanus who were admitted to the same facility during the same period. The potential risk factors of the neonatal tetanus group were compared with the control group using univariate analysis and an unconditional logistic regression model.Results：A total of 246 neonates with tetanus and 257 controls were included in this study. Univariate analysis showed that having untrained birth attendants, home delivery, an unsterile method of delivery and being a migrant to Wenzhou were significantly different between the two groups (P < 0.001). Logistic regression analysis revealed that the odds of having an untrained birth attendant, home delivery and an unsterile method of delivery were significantly higher in the tetanus group than the control group (odds ratio: 1371.0; 95% confidence interval: 206.0, 9123.5).Conclusion：This study identified that the main risks of neonatal tetanus in cases from Wenzhou were having an untrained birth attendant, home delivery and an unsterile method of delivery. Preventive measures directed to these risk factors may reduce the occurrence of neonatal tetanus in the studied area.

In this paper, the domestic varieties and quality standard of Leguminosae medicinal plants used in Tibetan medicine were analyzed. The results showed that there were 36 genera and 142 species (including varieties), as well as 64 medicinal materials varieties of Leguminosae plants were recorded in relevant literatures. In relevant Tibetan standards and literatures, there are great differences in varieties, sources, used parts, and efficacy of medicinal plants. Among them, about 38.0% (including 54 species) of the endemic plants, about 25.4% (including 36 species) of the original plants have medicinal standard legal records, except 9 kinds of traditional Chinese medicine general quality standard more fairly completed, the most varieties have only description about characters, identification, etc. Therefore it is necessary to reinforce study for the herbal textual, resources and the use present situation, chemical components and biological activity, quality standard, medicinal terms specification, to promote establishment of quality standard system for variety-terminologies-sources of Tibetan medicinal plants.
