TCM variety derived from classical or proved prescriptions and was improved through the innovation and development of clinical practices,controlling of medicinal raw material and producing process.The current protection system of TCM variety does not match the developing rule of TCM,in that there is no particular article to regulate traditional classical or proved prescriptions,self-made TCM preparations in hospitals,the genuineness of medicinal raw material and manufacturing techniques,and also lacks the relevant investment return mechanism.It was recommended of creating TCM protection category,protecting self-made TCM preparations in hospitals,regulating genuineness of medicinal raw material and establishing know-how protecting mechanisms,while protecting test data were suggested to be introduced for perfecting the protection system of TCM variety.

Objective To investigate the relationship between plasma leptin levels and obesity,plasma glucose as well as insulin concentrations.Methods Fasting plasma leptin concentrations were measured with IRMA in 171 cases (including 84 type 2 DM,36 IGT,51 NGT;90 men,81 women),and oral glucose tolerance test was done in every case to measure plasma glucose and insulin concentrations.Height,body weight were measured to calculate body mass index (BMI).Results Fasting plasma leptin levels are correlated with BMI( r=0.6772,P

Objective To improve the knowledge of mammographic signs of sclerosing adenosis.Methods The X-ray and pathological features of sclerosing adenosis of 17 focuses in 15 cases proved by histology were reviewed in comparison with that of breast cancer.The study was put emphasis upon the difference between sclerosing adenosis and breast cancer on clinic and radiographs.Results On mammography,the lesions appeared as asymmetric and disseminated density in 5/17(29.4%),dense nodules in 10/17(58.8%),calcifications inside the lesions in 3 and focal architectural disorder combined with stellate constriction in 2/17(11.8%).Conclusion The sclerosing adenosis is easily confused with breast carcinoma on radiographic signs,the diagnosis would be combined with clinical history and palpation examination.

Objective To report the experiences on the diagnosis and treatment of duplication of kidney ureter and bladder. Methods Nine cases of duplication of kidney ureter and bladder from 1996 to 2008 were reviewed.Six cases of duplicated kidney ureter occurred in the left side and 2 cases in the right side,1 case bilateral kidney ureteral duplication.Of 8 cases with unilateral duplicated,duplicated bladders were incompleteness.And the patient with bilateral duplicated,whose duplicated bladder was completeness,was diagnosed with duplication of urethra,uterine,bilateral ovary and oviduet tubes,and also suffered from duplicated uterine prolapse Ⅱ,vaginal anterior wall bulging and duplicated vesicocele.There were two cases whose duplicated kidney losed function because of severe hydronephrosis,and 7 cases existed kidney secretion function. Excision of duplicated kidney ureter and bladder were performed on 2 cases with non-functional duplicated kidney.6 cases had undergone duplicated bladder excision and duplicated ureteral bladder replantation.The special case had undergone duplicated urinary bladder urethra uterine and bilateral annexes excision,and duplicated ureteral bladder replantation. Results The operation was successful in all paients without leakage and ureter stump syndrome.Three months after operation,ureter bladder imaging showed no ureteral reflux in 7 cases of ureteral bladder replantation.IVU were reviewed 12 months after operation:2 cases undergoing duplicated kidney excision showed that the function of residual kidney were normal,7 cases of replantation that the shape and function of sick side kidney and duplicated kidney were good. The patient who suffered from duplicated uterine simultaneously got pregnancy 1.5 years after operation. Conclsions Image examinations may help to diagnose the duplication of kidney ureter and bladder. The main treatment is surgery. Understanding the function of duplicated kidney and the shape of kidney ureter and bladder should be considered before operation. The goal of surgery should be relieving pain,protecting the function of duplicated kidney and minimizing the risk of infection.

Objective To investigate the diagnostic value of CA125 and CA153 for the combined detection of the disease in breast cancer patients.Methods 100 cases of breast cancer patients were selected as the breast cancer group,and the same period 100 cases of benign breast lesions were selected as the benign group,100 cases of normal healthy subjects were selected as the control group.The expression levels of CA125 and CA153 in the three groups were detected.Results CA153 and CA125 levels in the breast cancer group was (78.4 ± 23.76) U/mL,(71.3 ± 24.7) U/mL; The benign group CA153 and CA125 content were (13.4 ± 3.7) U/mL,(20.6 ± 12.4) U/mL;CA153 and CA125 in the normal control group content were (0.9 ± 0.8) U/mL,(19.3 ± 11.3) U/mL; CA153 and CA125 in the breast cancer group were significantly higher than those of the benign group and the normal control group,the difference was statistically significant (F =34.15,28.42,all P ＜ 0.05) ; CA153 and CA125 alone detected in breast cancer detection rate was 31.0 ％,24.0 ％,respectively,combined detection of CA153 and CA125 in breast cancer detection rate was 66.0％,CA153 and CA125 alone detected in breast cancer detection rate was significantly lower than the combined detection CA153 and CA125 in the breast cancer detection rate (F =8.21,P ＜ 0.05).CA153 and CA125 expression of breast cancer patients after treatment than that of before treatment significantly reduced,and compare the data with statistically significant (t =21.82,22.31,all P ＜ 0.05).Conclusion The clinical detection of CA125 and CA153 united can effectively improve the diagnosis of breast cancer effect,combined detection of higher sensitivity and specificity.Meanwhile,the combined detection of breast cancer clinical monitoring also ha ssome significance,which is worthy of clinical application.

Objective·To identify the relationship between the estimated fetal weight (EFW) discordance and birth weight (BW) discordance, and evaluate the accuracy of ultrasonography in predicting birth weight discordance (△BW) of twin pregnancy. Methods·The ultrasound was used to detect the growth of twins at different gestational weeks and the data were analyzed to compare the difference between EFW discordance (△EFW) and ?BW. Results·About 15.9 percent of twins (totally 277 cases) had severe △BW (△BW ≥20%) in our study, and the percentages of dichorionic-diamniotic twin (DCDA) and monochorionic-diamniotic twin (MCDA) were 68.2% and 31.8%, respectively (P>0.01). Compared with △EFW in other gestational weeks,△EFW last time before parturition was most consistent of △BW. Furthermore, the negative predictive value of MCDA was highest (94%) at 22-24 gestational weeks. Conclusion·Twin △BW was relatively better predicted by △EFW last time before parturition. Twin pregnancy without severe △EFW (△EFW<20%), especially MCDA with △EFW<20% at 22-24 weeks, had low probability of selective intrauterine growth restriction in the future.

Objective To observe the effects of Chinese herbal compounds (alkaloid of Coptidis Rhizoma 40%, total saponin of panax notoginseng 35%, and polysaccharide of Ophiopogonis Radix 25%) on levels of blood glucose, fructosamine, and insulin of diabetic rats, and explore mechanism of action.Methods Ten rats were randomly chosen as blank control group, and other rats were used to establish diabetic rat models by STZ intraperitoneal injection. Successfully molding rats were randomly divided into Chinese herbal compounds high, medium, low dose groups, metformin group, and model group, 10 rats in each group. Each rat received gavage for continuous 4 weeks. Then rat blood was collected by cutting head and taking caudal vein. FBG was detected by glucose oxidase method;insulin level was detected by radio-immunity double antibody method;fructosamine content was detected by fructosamine method.Results Compared with the blank control group, model group the levels of FBG, froctosamine content increased, while fasting insulin level were lower after 4 weeks'medication. Compared with the model group, the levels of FBG, froctosamine content in Chinese herbal compounds high and medium dose groups and metformin group were lower, while fasting insulin level increased after 4 weeks'medication (P<0.05).Conclusion TCM herbal compounds can increased the basic insulin level by decreasing the contents of FBG and fructosamine.

In recent years,the role of phosphodiesterase 5(PDE5)has been highlighted in the development and progression of neurological disease.PDE5 inhibitors show significant effect of neruoprotection,which may be related with some effects such as resistance to stroke,anti-oxidation,inhibition of neuroinflammation and amelioration of cognitive deficits.Based on the domestic and overseas researches about PDE5,this review systematically summarized the neuroprotection of PDE5 and their related mechanisms.

Objective To observe the effects of Hedysari Polysaccharide (HPS) on the expressions of TSP-1 and PDGF-B in the retina of diabetic rats;To discuss the protective effect and possible mechanism on diabetic retinopathy. Methods The diabetic model was established by intraperitoneal injection of streptozotocin. 50 male SPF Wistar rats were randomly divided into 5 groups:model group, calcium dobesilate group, and HPS high-, medium-, and low-dose group, extra 10 rats were set as the normal group, 10 rats in each group. Each administration group was given relevant medicine for gavage, while model group and normal control group were given same amount NS for gavage, once a day for 8 weeks. The mRNA and protein expression of TSP-1 and PDGF-B were detected by qRT-PCR and immunohistochemistry. The retinal structure was observed by HE staining. Results HE staining showed that each layer of the retina of the model group was clear and complete, but the outer nucleus layer became looser, thinner and more disorderly, and the number of ganglion cells decreased slightly; the administration groups were improved markedly compared with the model group. Compared with the normal control group, the mRNA level and protein expression of retina TSP-1 on the model group dramatically dropped (P<0.01), and those of PDGF-B strikingly increased (P<0.01);Compared with the model group, the mRNA level and protein expression of retina TSP-1 on alladministration groups rose (P<0.05, P<0.01), and those of PDGF-B went down (P<0.01); Compared with all other administration groups, there was statistical significance in the mRNA level and protein expression of retina TSP-1 and PDGF-B on HPS high-dose group (P<0.05, P<0.01). Conclusion HPS may prevent the angiogenesis and proliferation in diabetic retinopathy process through adjusting the content of TSP-1 and PDGF-B in retina of diabetic rats so as to protect the retina.

Objective To study the recombination type of B/C genotype in hepatitis B virus.Methods The PCR was applied to amplifed the whole genes of HBV through the serums of four chronic HBV carriers who come from Jinghong distict,Yunnan province.The whole HBV genomes were ligated with pMD18-T vector and trasformed to E.coli JM109.After the positive colones were picked up,the HBV genotypes and recombinated sites were discoved through sequenced the acquired positive colones.Results All the acquired sixteen HBV sequences from the four HBV carriers were genotype B which were combinated with genotype C in some region.There are two ways of the combinations.For the first one,a 496 bp fragment from genotype C taked place the genotype B at the place of nt1825 to nt2320 of precore C/C region.For the second way,a 695 bp fragment of genotype B taked place at the both sites of nt822 to nt1020 of P gene region and nt1825 to nt2320 of precore C/C region.Conclusion A new recombination type of B/C genotype in hepatitis B virus was reported for the first time.The new Bj subgenotype was combinated with genotype C not only at the region of precore C/C but also at the place of P gene region.
