With the advancement of medical and health system,the reform of medical price became one of cores in new medical reform.According to the principle of "the total quantity control,the structure adjustment",in recent years,every region adjusted the medical price.However,the regional medical price disharmony was influenced by the mechanism of information-sharing,the differentiation right of pricing and management and setting basis and cycle.It followed the regional medical price disharmony concern over the principle,content and method of mechanism of regional medical price coordination for optimizing medical price management,so as to provide references for further optimizing medical service price management.

In order to investigate the mechanism, the correlation between the odor change in Crataegi Fructus stir-fried process and 5-HMF were studied. Required samples were retrieved from Crataegi Fructus stir-fried process. Statistical quality control (SQC) was used to analyze the response values acquired by the electronic nose. At the same time, the content of 5-HMF was detected by high performance liquid chromatography (HPLC). Correlation analysis was used to analyze the relationship between the above two. Experimental results showed that SQC model established by response values of all samples could show the change law of odor in Crataegi Fructus stir-fried process and changes of 5-HMF content was dropped after the first increase. Correlation analysis showed that the odor change in Crataegi Fructus stir-fried process and 5-HMF were significantly correlated (P < 0.05). Sugar degradation reaction and the Maillard reaction may be one of the mechanisms of the odor change in Crataegi Fructus stir-fried process.

Objective To evaluate the safety and feasibility of laparoscopic left hepatectomy in patients with primary hepatic carcinoma. Methods Retrospective analysis was conducted in clinical data of left hepatectomy from 2007 to 2014,including 47 cases of laparoscopic hepatectomy and 46 cases of open hepatectomy. The intraoperative and postoperative data of the two surgical methods were compared to evalu-ate whether laparoscopic left hepatectomy is safe and feasible. Results The tumor size were bigger in the open hepatectomy [(56. 57 ± 24. 56) mm vs. (64. 11 ± 33. 39) mm,P=0. 218]. The laparoscopic left hepatectomy resulted in shorter operation time [(217. 53 ± 60. 22) min vs.(306.80±119.91)min],andtherewasasignificantlydifference(P<0.05).Theintraoperativebloodlosswerelesserinthelaparo-scopic left hepatectomy [(350. 21 ± 197. 98) mL vs. (556. 74 ± 471. 41) mL],and there was a significantly difference (P<0. 05). The lap-aroscopic left hepatectomy had a smaller intraoperative blood transfusion rate (12. 8% vs. 32. 6%,P<0. 05). The length of ICU stay,time for gastroentestinal function recovery, postopetative hospital stay were shorter than those of open left hepatectomy (P<0. 05). There was no significant difference of postoperative complication rate between them (14. 9% vs. 23. 9%,P=0. 271). The survival rates of 1-and 3-year after operation in patients with laparoscopic left hepatectomy were 91. 5% and 83. 0% respectively,while 84. 8% and 76. 1% in patients un-derwent open hepatectomy. The tumor-free survival rates 1-and 3-year after operation were 74. 5% and 59. 6% in patients with laparoscopic left hepatectomy respectively,while 65. 2% and 54. 3% in patients underwent open hepatectomy. Conclusion Laparoscopic left hepatectomy for primary hepatic carcinoma is safe and feasible. Laparoscopic left hepatectomy could be a consideration as the standard surgical methods for hepatic carcinoma.

The inundation of Cordyceps sinensis counterfeits in the market makes it difficult to identify. In this study, 21 batches of wild C. sinensis from 3 different regions, 30 batches of naturally cultured C. sinensis and 4 kinds of counterfeits extracted by methanol and water were analyzed using NMR technology. 9 characteristic peaks were defined as quantitative criterion after comparison, and NMR fingerprints of C. sinensis were established. According to the result it is highly similar between naturally cultured C. sinensis and wild ones by comparing their NMR fingerprints. However, NMR spectra of four kinds of adulterants showed differences with C. sinensis. The result also showed that NMR fingerprint of C. sinensis are highly characteristic and specific. The NMR characteristic fingerprint of wild C. sinensis was consistent with the naturally cultured C. sinensis, and it indicated that the chemical constituents of wild C. sinensis and naturally cultured C. sinensis are nearly the same.

This study was aimed to distinguish Leonurus japonicus samples produced from different regions and growth environments in Sichuan by electronic nose.

OBJECTIVETo observe the effects of H. dulcis on relieving alcohol toxicity by animal experiments.

METHODMale kunming mice were ovraiectomized and randomly divided into 5 groups: control group, model group, and aqueous extracts of H. dulcis group at 0.5, 0.25, 0.125 g x mL(-1). The acute alcohlism animals induced by gastral administration with "Er Guo Tou" and the alchol concentrations in serum were detected after treated with the extracts within 0.5-3 h by biochemical enzymes.

RESULTThe alcohol concentration in blood was up to the maximum in 0.5-1.5 h. However, the alcohol concentrations in blood of aqueous extract from H. dulcis group were decreased in 0.5-3 h. The activity of ADH in the liver in aqueous extract of H. dulcis group was increased in 2-3 h, while it was significantly increased in 1-1.5 h (P <0.05).

CONCLUSIONThe aqueous extract of H. dulcis could reduce the alchol concentration in blood of animals and inrease the activity of ADH after given alcohol. It means the extract has the effect of relieving alcohol toxicity and preventing drunkenness through restraining the absorption of alcohol in the gastrointestinal tract and promoting the metabolism of alcohol in the liver.

Objective To know the condition and feature of water-born endemic arsenism in Shaanxi province, and to provide scientific evidences for prevention and treatment of the disease. Methods In 2009, 8 villages of Duhe, Miaogou, Sanhe, Caiyuan in Shanyang county and Shuanglong, Guangming, Donghekou in Zhen'an county and Guojiawan in Mian county as monitoring sites from both the found water-born arsenic poisoning areas and potential ones of drinking water arsenic ＞ 0.15 mg/L were selected. The disease conditions of residents who lived for more than six months of continuous residence, were investigated according to "Endemic Arsenism Diagnostic Criteria" (WS/T 211-2001 ) and arsenic level in the drinking water were determined. Results Seven thousand six hundred and ninety-three individuals were investigated and 612 cases of arsenism were diagnosed in the 8 villages, the prevalence rate was 7.96%(612/7693). Mild patients accounted for 33.17%(203/612), moderate patients accounted for 50.16%(307/612), and severe patients accounted for 16.67%(102/612). The detection rate for male was 9.99%(408/4085), for female was 5.65%(204/3608), the former was higher than the latter(x2 = 49.138,P ＜ 0.01 ). The older the age was, the higher the rate was(x2 = 770.708, P ＜ 0.01 ). Main clinical manifestation of the patients was depigmentation and pigmentation in skin. Patients with one symptom accounted for 43.30% (265/612), with two symptoms accounted for 56.70% (347/612). Three hundred and seventy drinking water samples were detected, the median of arsenism content was 0.005 mg/L, ranged 0 - 1.660 mg/L. The over-limit rate of arsenic level in the drinking water were 11.62% (43/370). Conclusion Water-born endemic arsenism is mildly prevailing in Shaanxi province, however, great attention should be given to control and monitoring of the disease.

Objective To investigate the current situation of endemic fluorosis associated with drinking water in Shaanxi province in 2008, providing prevention and control work with scientific evidence. Methods According to data of drinking water endemic fluorosis in Shaanxi, 15 counties in Yulin, Weinan and Xianyang city were divided into mild, moderate and severe diseased areas according to fuoride level in the drinking water or the fluorosis severity, and 12,39,45 endemic fluorosis villages were selected respectively from each area. Dental fluorosis for all the children aged 8 - 12 years old and clinical skeletal fluorosis for the people over the age of 16 were examined. In mild, moderate and severe areas, 30% of the survey villages received X-ray to examine skeletal fuorosis. Five water samples were collected from villages with unimproved water respectively from the east, the west, the south, the north, the middle; if there was less than 5 that could be sampled, then all were collected, moreover 3 peripheral and 1 central water samples were collected from villages with improved water. Also in mild, moderate and severe illness areas, 50% of the surveyed villages were selected; in each village, 30 urine samples of the children aged 8 - 12 were collected, 6 portions in each age group. If Less than 30 children in all the age groups or less than 6 in each age group, all their urine samples were collected to determine fluoride. Results Totally 3652 children aged 8 - 12 years old were examined and 1930 cases of dental fluorosis were diagnosed, the rate was 52.85% and the index was 1.22. The rates in Dinghian, Jingbian and Pucheng village were higher, being 90.43% (170/188) ,82.89%(126/152),80.65% (325/403) respectively. A total of 40 543 adults over the age of 16 were examined and 5935 cases of skeletal fluorosis were diagnosed, in a rate of 14.64%. The rates of the mild, moderate, severe skeletal fluorosis were respectively 9.17%(3717/40 543),4.36%(1769/40 543),1.11%(449/40 543).All 706 adults were taken X-ray films.and 280 cases of positive change were diagnosed,the positive rate was 39.66%. The rates of the mild,moderate,severe change were respectively 17.28%(122/706),17.00%(120/706),5.38%(38/706).All 427 water samples were collected,the fluoride content waS(2.22±1.41)ms/L,and the abnormal rate was 85.01%(363/427).All 1393 portions of urine sample were collected in children and the median of fuoride was 2.37 mg/L Conclusions The endemic fluorosis associated with drinking water is still comparatively serious in Shaanxi.The preventive measures for improving water must be improved.

OBJECTIVETo establish a set of suitable and reliable methods for HBV genotyping and to study the distribution of HBV genotypes.

METHODSType-specific nucleotides were searched through alignment of S genes (more than 1000 sequences) listed in GenBank. Then, type-specific primers were designed and type-specific primer PCR was used to genotype the 238 HBV strains. S genes of the untyped strains were further amplified and sequenced to find out their genotypes with type-specific nucleotide analysis.

RESULTSAll the 238 HBV strains were genotyped. 159 (66.8%) cases were genotype B, 69 (28.9%) were genotype C, 6 (2.5%) were mixtures of genotypes B and C and 4 (1.6%) were mixtures of genotypes B and D. No genotypes of A, E, F, G, and H were found.

CONCLUSIONGenotypes B and C are the most common types for HBV strains. Mixtures of genotypes B and C or genotypes B and D coinfection rarely existed. There is no relationship between the gender of the patients and HBV genotypes (X2 = 0.794, P more than 0.05).
