Objective:To compare the clinical characteristics in primary hyper(-) parathyroid hormone (PHPT) of the different patholog-ic types. Methods:Clinical data of 140 patients with PHPT proved by operation and pathology during January 2010 to June 2016 were retrospectively analyzed. Results:A total of 140 PHPT patients, including 13 (9.29%) cases of parathyroid carcinoma (PC), 27 (19.29%) cases of parathyroid hyperplasia (PH), and 100 (71.43%) cases of parathyroid adenoma (PA). The duration of the PC group was longer than the PH group and the duration of the parathyroid adenoma (PH) group was longer than the PA group (P<0.05). The percentage of young patients with PC was higher than in the other two groups (P=0.003). The diameters of the PC group were larger than those of the other two groups, and those of the PA group were larger than those of the PH groups (P<0.05). Blood calcium, parathyroid hor-mone (PTH), AKP, fasting blood glucose (FBG), alanine aminotransferase (ALT), aspartate aminotransferase (AST), glutamete transpepti-dase (GGT), blood urine nitrogen (BUN), creatine (CRE), urinary calcium, and phosphorus of the PC group were higher than in the oth-er two groups (P<0.05). The blood calcium, PTH, alkaline phosphatase (AKP), urinary calcium of the PH group were lower than those in PA group (P<0.05). The proportion of ostalgia was 46.15%(6/13), 44.44%(12/27), and 49.00%(49/100). No statistical difference was observed (P>0.05). The postoperative calcium level of PC group was lowest (P<0.001), and the highest was of PTH (P<0.001). The pro-portions of clinical manifestation of the urinary system, digestive system, and nervous system in the PC group were 76.92%(10/13), 76.92%(10/13), and 15.38%(2/13), respectively, and these values were the highest in the three groups (P<0.05). The proportion of the clinical manifestation of the urinary system of the PH group was higher than that of the PA group. The fracture rate (30.77%, 4/13) and constipation rate (38.46%, 5/13) of the PC group were the highest among the three groups (P<0.05). Conclusion:The duration of patients with PC was the longest among the three groups. The percentage of young patients with PC was the highest. The abnormal parathyroid glands in the PC group were the heaviest. The PC group exhibited the lowest postoperative calcium level and the highest PTH level. The biochemistry and clinical manifestations of PC were obvious.

OBJECTIVE: To develop the accelerated solvent extraction (ASE) for determining pesticides present in blood samples. METHODS: Pesticides were extracted by ASE with optimized parameters to study recovery rate affected by extraction temperature, time and agent. GC/MS was used to perform quantitative analysis. RESULTS: The recovery rates of eight pesticides were 70.6%-92.4%. The coefficient of variation was less than 5.0%. A good linear relationship was obtained at the concentration range of 0.5-5.0 microg/mL. CONCLUSION The method was fast and simple with high recovery rate and good repeatability. It can be applied to analyze pesticides present in the blood specimen.

Objective To study the efficacy and safety of tacalcitol combined with monochromatic excimer light (MEL) 308 nm vs MEL 308 nm monotherapy in treating vitiligo.Methods Thirty-eight pa- tients with vitiligo were enrolled in the single-blind clinical trial,using plabebo-treated lesions in the same patient as controls.Contralateral or nearby lesions were randomly selected to be treated by either tacalcitol or placebo.All lesions were treated weekly with MEL 308 nm,for a total of 12 sessions.Patients were ex- amined at monthly intervals.The mean number of sessions and the cumulative dosage for initial and excel- lent repigrnentation were calculated.Results Thirty-five patients were evaluated.The mean?SEM cumu- lative dose and number of MEL exposures for initial repigmentation,respectively,were 4.27?3.59 J/cm~2 and 4.89?3.16 on tacalcitol-treated site,5.36?4.12 J/cm~2 and 5.69?3.29 on placebo-treated site,re- spectively (both P＜0.05).For excellent repigrnentation,the cumulative dose and number of exposures were 7.72?5.64 J/cm~2 and 7.79?4.70 respectively on tacalcitol-treated site,and 8.18?4.87 J/cm~2 and 8.4?3.92 respectively on placebo-treated site (both P＞0.05).Treatment with tacalcitol resulted in a sig- nificantly higher percentage (71.4% vs 54.3%) of repigmentation than that with placebo.Conclusions Our results show that MEL 308 nm is safe and effective for the treatment of vitiligo.Additionally,concur- rent topical tacalcitol potentiates the efficacy of MEL 308 nm in the treatment of vitiligo;this combination achieves more rapid pigmentation with a lower total MEL dosage.

To study the clinical application of Jintian'ge capsule in treatment of vertebral compression fracture in senile osteoporosis patients. In the study, 69 senile osteoporotic vertebral compression fracture patients hospitalized in our hospital between January 2012 and June 2014 were selected and randomly divided into the control group and the treatment group. Patients in the control group were treated by percutaneous kyphoplasty (PKP), while those in the treatment group were given Jintian'ge capsule in addition to PKP. Efforts were made to visit the patients before the surgery and in three month after that, observe and compared the vertebral height, Cobb's angle, bone density, visual analogue scale (VAS) and Oswestry disability index between patients in the two groups. According to the findings, compared with before the treatment, patients in the two groups showed significant improvements in the vertebral height, Cobb's angle, bone density, VAS and Oswestry disability index three months after the surgery (P < 0.05); During the visit three months after the treatment, compared with the control group, the treatment group showed notable increases in all parameters (P < 0.05), particularly in the vertebral height, VAS and Oswestry disability index (P < 0.05). Based on the above findings, Jintian'ge capsule is applicable in adjuvant therapy after the osteoporotic vertebral compression facture PKP surgery.

Abstract: Objective　A survey on the plague foci in Qiaojia County of Jinsha River Basin was conducted to understand the composition of plague host vectors and the prevalence of plague among animals, to explore the occurrence and epidemic risk of plague, and to provide scientific basis for plague monitoring and control in this area. Methods　Seven villages and towns in Qiaojia County were selected as the research areas, and the cage night method and the clamp line method were used to investigate the small mammals and their surface parasitic fleas. The host animal organs, serum and surface parasitic flea's samples were collected. The plague indicator animal serum was collected simultaneously on the spot, and the collected host animal organs and flea's samples were cultured and detected for Yersinia pestis. The indirect hemagglutination test (IHA) was used to detect the fraction 1 capsular antigen (F1) antibody of the host animal and the indicator animal serum samples. Results　A total of 525 small mammals belonging to 3 orders, 6 families, 12 genera and 23 species were captured. The dominant species in farming areas were Apodemus chevrieri (31.05%), Niviventer confucianus (13.90%) and Anourosorex squamipes Milne-Edwards (11.43%). The dominant species in residential areas were Rattus norvegicus (66.67%) and Rattus tanezumi (20.00%). The rat densities in agricultural and residential areas were 20.98% and 1.00%, respectively. A total of 277 external parasitic fleas belonging to 15 species, 13 genera, 5 families were collected. The dominant species were Palaeopsylla remota (22.02%), Neopsylla specialis specialis (20.58%), Frontopsylla diqingensis (18.77%) and Ctenophthalmus (Sinoctenophthalmus) quadratus (11.55%), and the rat fleas index was 0.53. No Yersinia pestis was isolated from all rodent organs and flea samples. A total of 167 serum samples from dogs and 15 serum samples from rats were collected, and plague F1 antibody was detected by IHA. IHA detection of plague F1 antibody were negative. Conclusions　Qiaojia County has the distribution of the main host and main vector of plague, and the rat density is high, but the rat body flea index is low. There is no positive detection of plague host animals, vector fleas and indicator animals. It can be considered that the risk of plague occurrence and epidemic in the region is not high in the near future. It is necessary to further strengthen the monitoring and control of plague and other rodent-borne diseases in the region.

Objective To evaluate the efficacy and safety of adefovir dipivoxil(ADV)in treating patients with hepatitis B e antigen(HBeAg)positive chronic hepatitis B.Methods In this randomized,double blind,placebo-controlled,multicenter trial,210 eligible patients with HBeAg positive chronic hepatitis B were recruited and randomized(randomization ratio was 2:1)receiving ADV 10 mg/d for 48 weeks(ADV+ADV group,n=142)or placebo for 24 weeks followed by ADV 10 mg/d for 24 weeks(PLB+ADV group,n=68).The primary endpoint was virological response. The secondary endpoint was serologic response(HBeAg loss rate and HBeAg seroconversion rate) and alanine aminotransferase normalization rate.Results After 24 weeks therapy,mean reduction of hepatitis B virus(HBV)DNA level comparing with that of baseline was 3.12 log_(10)copy/mL in ADV +ADV group while it was 0.95 log_(10)copy/mL in PLB+ADV group.The percentages of patients with HBV DNA clearance(HBV DNA level

AIM To study the formation rules of baicalin-berberine complex.METHODS Under the conditions of different ratios of baicalin to berberine,heating methods and media (pH,ionic strength),the yield and composition of mixed decoction precipitation were determined by HPLC.RESULTS 0.5 g Baicalin and 1 g berberine produced the highest amount of precipitation.Higher heating temperature,nearly neutral pH (6.8) and glucose addition were beneficial to precipitate generation,in sharp contrast to NaCl addition.CONCLUSION The yield and composition of baicalin-berberine complex are mainly influenced by heating temperature and additives.

Objective To study the association between functional genetic polymorphisms of IL-1B(T-31C,C-511T),IL-1RN and the susceptibility to gastric cancers. Methods A case-control study was conducted in 180 gastric cancer cases and 308 age-and sex-matched cancer-free controls.Genotypes were detected by PCR-restriction fragment length polymorphism(PCR-RFLP) assays,and association between genotypes,environmental factors and risk of gastric cancers were determined. Results IL-1B T-31C was in strong linkage disequilibrium with IL-1B C-511T(D'=0.862,R2= 0.721,P=0.000).Multivariate logistic regression analysis revealed that the variant genotypes of IL-1B T-31C and C-511T were not significantly associated with risks for gastric cancers(adjusted OR,0.95 and 95% CI,0.62-1.47 for IL-1B T-31C;and adjusted OR,0.85 and 95% CI,0.55-1.31 for IL-1B C-511T).The variant genotypes(1/2,2/2) in IL-1RN were associated with a non-significantly increased risks for gastric cancers(adjusted OR,1.32 and 95% CI,0.71-2.36) in all subjects and with a significantly increased risks for gastric cancers in subjects with H.pylori infection(adjusted OR,2.03 and 95%CI,1.02-4.80).Conclusion The functional genetic polymorphisms of IL-1RN may contribute to the risks of gastric cancers in high-risk population,particularly in those with H.pylori infection.
