Objective To determine the clinical value of MRCP for peroperative evaluation of donor biliary system in living donor liver transplantation (LDLT). Methods A total of 60 living donors for the LDLT were enrolled in this study. Of the 60 donors with a mean age of 32.2 (19-60), 50were male and 10 female. MRCP was performed before and cholangiography was done during the right lobectomy in these donors. The results of MRCP were compared with those of cholangiography to determine the value of MRCP for typing the biliary system in the donors. Results The preoperative MRCP showed that 40 donors were of type Ⅰ biliary tract, 12 of type Ⅱ , 5 of type Ⅲ and 3 of other types. The intraoperative cholangiography showed that the accordance rate of MRCP was 97.4%,91% and 89% for type Ⅰ , type Ⅱ and other types, respectively. The overall rate of accuracy of MRCP was 95% (57/60). Conlusion MRCP can show types of biliary tract in living donors for liver transplantation to provide evidence for plan of surgery.

OBJECTIVE: To compare the concentration of teeth DNA extracted by three different pretreatment methods and to explore a simple, economical and practical pretreatment method with high concentration of extracted DNA from teeth. METHODS: A total number of 21 molars were collected from 7 corpses. The pretreatment of 3 molars from each individual was randomly performed by tooth crumb method, ball-milling method and liquid nitrogen milling method and 50 mg tooth crumb was weight and DNA was extracted by AutoMate Express forensic DNA extraction system. Subsequently, the concentration of DNA and corresponding STR genotyping of three methods were compared. RESULTS: The DNA concentration extracted by tooth crumb method, ball-milling method and liquid nitrogen milling method was 0.055 6-1.989 1 ng/μL, 0.036 6-1.175 6 ng/μL and 0.037 8-1.249 0 ng/μL, respectively. The DNA concentration obtained by tooth crumb method was higher (P < 0.05) and the success rate of STR genotyping was high. CONCLUSION Combined with AutoMate Express forensic DNA extraction system, tooth crumb method is an efficient and feasible method to extract DNA from teeth, which can be applied in forensic practice.

OBJECTIVETo explore the clinical and physical factors that might give rise to radiation-induced esophagitis in three-dimensional conformal radiotherapy for non-small cell lung cancer.

METHODSTo collect the clinical and physical records and follow-up information of 106 NSCLC patients without undergoing surgery in our hospital. χ(2) test, linear tendency test and analysis of variance were employed to analyze the relationship between occurrence of radiation-induced esophagitis and clinical and physical treatment. Logistic analysis was also used for multivariate analysis.

RESULTSAmong the 47 cases of radiation-induced esophagitis, 31 cases were of grade I, 11 of grade II, 5 of grade III, and with a total occurrence rate of 44.3% (47/106). Radiation-induced esophagitis was correlated with Karnofsky scores, radiation sensitization and tumor location (χ(2) = 11.30, 8.45, 7.67, P < 0.05). Radiation-induced esophagitis was correlated with the length of irradiated esophagus and average dose of irradiated esophagus (F = 20.82, 83.08, P < 0.001). With the increase of the irradiated volume percentage from V20, V30, V40 up to V50, the occurrence rate of radiation-induced esophagitis was also increased, almost with a linear trend (P < 0.05). Application of all the above factors to logistic model indicated that radiation sensitization,length of irradiated esophagus, average dose and V50 were all statistically significant foactors in the occurrence of radiation-induced esophagitis (OR = 0.321, 2.850, 7.307 and 8.558, P < 0.05).

CONCLUSIONSRadiation sensitization,length of irradiated esophagus, average dose of irradiated esophagus and V50 are independent factors in the occurrence of radiation-induced esophagitis. V50 is of greater importance in the judgement of occurrence of radiation-induced esophagitis.

Objective To examine serum levels of complement component 3(C3), complement component 4(C4), high sensitivity C reactive protein (hs-CRP), and uric acid (UA) in schizophrenia (SZ) patients and study their clinical significance. Methods One hundred forty-four SZ patients were recruited as SZ group. According to use of antipsychotics within four weeks, patients were divided into drug group (77 cases) and non-drug group (67 cases). One hundred forty-seven healthy subjects from health checkup center in the second XiangYa hospital during the same period were selected as control group. The concentrations of serum C3, C4, hs-CRP, and UA from SZ patients and healthy subjects were measured using immuno-scatter turbidmetry, latex-enhanced immunoturbidimetric assay, urea oxidase method, respectively. Results The serum levels of complement C3 and C4 were lower in SZ patients than in control group [(0.99±0.17) g/L vs. (1.03±0.17) g/L、(0.21±0.05) g/L vs. (0.23±0.05) g/L], and the serum levels of UA in serum of was higher in SZ patients than in control group [(351.61±95.90) μmol/L vs. (300.28±39.57) ?mol/L]. The differences had statistical significance (P<0.05, P<0.05, and P<0.001, respectively). The serum levels of C3, C4, hs-CRP, and UA were higher in drug group than in no-drug group [(1.04±0.19) g/L vs. (0.95±0.15) g/L、(0.22±0.06) g/L vs. (0.20±0.05) g/L、1.08(0.33, 5.04) mg/L vs. 0.47(0.28, 1.29) mg/L、(374.54±108.33)μmol/L vs. (331.61±79.03)μmol/L], and the differences had statistical significance (P<0.01).The concentrations of serum hs-CRP and UA were higher in drug group than in control group[1.08(0.33, 5.04) mg/L vs. 0.61(0.33, 1.26) mg/L、(374.54±108.33) μmol/L vs. (300.28±39.57) μmol/L], and differences had statistical significance (P<0.001). Conclusion The serum levels of C3, C4, hs-CRP, and UA in SZ Patients will be of guiding significance for clinical diagnosis of SZ and efficacy evaluation of antipsychotic drugs.

This study was aimed to reveal the species characteristics of Chinese patent medicines for antitussive ef-fect and provide references for developing new drugs. This research targeted Chinese patent medicines for antitussive effect which were included in the Pharmacopoeia of the People's Republic of China and the New National Chinese Patent Medicines as well as those characterized by keywords such as cough cure, cough alleviating, antitussive effect, cough, persistent cough. The analysis was made on the species characteristics, such as the number of Chinese patent medicines for antitussive effect, license number, ethnomedicine patent medicines, drugs for children use, protection of varieties of traditional Chinese medicine, the number of drugs, the generic names of drug, and drug forms. The results showed that 684 Chinese patent medicines for antitussive effect collected in this research had ac-counted for 8.60% of the total 7 260 of Chinese patent medicines. A total of 7 450 license numbers were approved, and 33% of the Chinese patent medicines shares one license number. One Chinese patent medicine owns 16.6 li-cense numbers on average. Ethnomedicine patent medicines had 3 Tibetan prescriptions such as the Shiwuwei Chenxiang pill and 4 Mongolian prescriptions, such as the Siwei Tumuxiang powder. Drugs for children accounted for 14%, including 9 forms. The type of the generic names of drug reached 16 and most of them originate from abbrevia-tions of the main drug in prescription. The number of drugs in prescription ranges from 8 to 16. Chinese patent medicines for antitussive effect involved 16 forms, of which the proportion of the use of solid preparation was higher than the liquid preparation. It was concluded that Chinese patent medicines for antitussive effect were characterized by such advantages such as a variety of species, various forms, the reasonable number of drugs, considerable medicine retail market share and drug for children use which can meet the clinical needs, and meanwhile some prob-lems, such as a lack of criteria for the generic names of drug, the homogenization of fierce competition, and inade-quacy of ethnomedicine patent medicines.
