Objective To explore the application value of hemi-hepatic blood flow occlusion through descending hilar plate in laparoscopic anatomic hepatectomy.Methods The clinical data of 15 patients who underwent laparoscopic anatomic hepatectomy by hemi-hepatic blood flow occlusion using descending hilar plate technique at the First People's hospital of Foshan between August 2012 and May 2014 were retrospectively analyzed.The hilar plate was bluntly dissected to expose the left and right Glissonean pedicles.Either side of Glissonean pedicle was tied up with a turnable aspirator with a cotton rope or shoelace and then bypassed the back of hilar plate.Anatomic hepatectomy was performed when hemi-hepatic blood flow was occluded.The follow-up by telephone interview and outpatient examination was done till October 2014.Results Among the 15 patients,the conversion to open surgery was done in 1 patient,Pringle maneuver in 1 patient,and hemi-hepatic blood flow occlusion by descending the hilar plate in 14 patients.Thirteen patients received succesfully laparoscopic anatomic hepatectomy by hemi-hepatic blood flow occlusion using descending hilar plate technique,including 4 of left hemihepatectomy,4 of left lateral lobectomy,2 of right hemihepatectomy,1 of right posterior lobectomy,1 of segment Ⅳ hepatectomy and 1 of segment Ⅵ hepatectomy.Bile duct exploration was applied to 4 patients with left hepatic duct stones and T-tube was placed in 2 patients.Nine and 4 patients received left and right hemi-hepatic blood flow occlusion,respectively.The operation time,mean volume of intraoperative blood loss and time of hemi-hepatic blood flow occlusion in 13 patients were (196 ±63)minutes,320 mL (range,50-1 200 mL) and (51 ± 20)minutes,respectively.The time of descending the hilar plate in 14 patients was (10 ±4)minutes.Among the 13 patients,bile leakage was detected in 1 patient with a maximum volume of drainage of 120 mL/day,liver wound bleeding in 1 patient with a volume of abdominal bloodstained drainage of 400 mL at postoperative day 2.Two patients were cured by conservative treatment,and no liver failure and perioperative death were occurred.The duration of hospital stay was (6.9 ± 2.4)days.Among the 15 patients,2 patients were loss to follow-up and other patients were followed up for 5-26 months with good survival,1 patient died.Conclusion Hemi-hepatic blood flow occlusion through descending hilar plate in laparoscopic anatomic hepatectomy is safe and feasible.

OBJECTIVE:To compare Paliperidone sustained-release tablet and Paliperidone palmitate injection in the treatment of schizophrenia in respects of medium-term and long-term efficacy,safety,insight,medication compliance and social function of patients,so ad to provide reference for drug selection in the clinic.METHODS:Eighty-four schizophrenia patients selected from our center during Mar.2015-Jun.2016 were divided into Paliperidone sustained-release tablet group (group H,44 cases) and Paliperidone palmitate injection group (group Z,40 cases).Group H was given Paliperidone sustained-release tablet orally with initial dose of 3 mg/d,gradually increasing to 9 mg/d 2 weeks later according to disease condition;the drug dose was adjusted and ranged 3-12 mg/d according to disease condition.Group Z was given Paliperidone palmitate injection intramuscularly,150 mg on 1st day,100 mg on 8th day,and then given injection once a month,drug dose was adjusted according to disease condition (75,100,150 mg).Treatment course of 2 groups lasted for 12 months.Before treatment,1,2,3,6,9,12 months after treatment,Positive and Negative Syndrome Scale (PANSS) was used to evaluate therapeutic efficacy;Scale to Assess Unawareness of Mental Disorder (SAUMD) was used to evaluate the cognition of patients to disease;Medication Adherence Rating Scale (MARS) was used to evaluate medication compliance;Personal and Social Performance Scale (PSP) was used to evaluate patient's social function.The occurrence of ADR was observed during treatment.RESULTS:3,2 patients withdrew from group H,Z during treatment.Before treatment,there was no statistical significance in PANSS,SAUMD,MARS,PSP scores between 2 groups (P＞0.05).1,2,3,6,9,12 months after treatment,PANSS and SAUMD scores of 2 groups were decreased significantly,while MARS and PSP scores were increased significantly,compared to before treatment,with statistical significance (P＜0.05).9,12 months after treatment,PANSS and SAUMD scores of group Z were decreased significantly,while MARS and PSP scores were increased significantly,compared to group H,with statistical significance (P＜0.05).There was no statistical significance in the occurrence of ADR between 2 groups (P＞0.05).CONCLUSIONS:For schizophrenia,Paliperidone palmitate injection is better than Paliperi done sustained-release tablet in respects of medium-term and long-term efficacy,patient's insight,medication compliance,social function recovery;the longer the time,the more prominent the superiority.There is no significant difference in safety between them.

AIM: To study the effect of garlicin on protecting nonalcoholic fat liver in rats induced by high fat diet and explore the pathogenesis involved. METHODS: According to the dosage of garlicin and diet, fifty SD rats were randomly divided into five equal groups: normal control group, model control group and garlicin (10, 20, 30 mg/kg) groups. Apart from the rats in normal control group, the rats were all fed with high fat and high cholesterol diet. After 12 weeks, the levels of serum endotoxin (ETX), total cholesterols (TC), triglyceride (TG), superoxide dismutase (SOD), malondialdehyde (MDA), transaminase and free fatty acids (FFA) were detected. The levels of MDA, SOD, glutathione hormone (GSH) in hepatic tissue were also detected. Then the features of live pathology were observed. RESULTS: The levels of ETX, TC and TG in garlicin groups were significantly lower than those in model control group (P

The existing processing methods, commercial specification and grades, and the marketing of Coptidis Rhizoma were systematical researched, referring to ancient, modern and contemporary medical literatures with the combination of our fieldwork on main origins of Coptidis Rhizoma and some herbs markets. Results showed that Coptidis Rhizoma processing methods mainly included sun-dried method and baked method anciently. For now, the processing methods become various, including thin paper-covering under the sun drying, direct drying, oven drying and microflame-fry drying. In the literatures, the main chemical constituent berberine was determined of its content to analyze the processing methods, finding that the sun drying and baked drying affect the berberine content, so the temperature must be controlled when drying. The thin paper-covering drying method is so cumbersome for large quantities of medicinal herbs and in wind conditions that it has been eliminated. Eventually, direct drying, oven drying and microflame-fry drying are chosen to the large-scale socialized production for their convenient and simple operation, making up the current main processing methods. Coptidis Rhizoma products have 3 specifications of Weilian, Yalian, Yunlian, of each specification there are 2 levels, but in fact the market of Weilian commodities overtakes the Yunlian, which only sold in parts of Yunnan, and the no-sale Yalian. The mainstream commercial Weilian are often sold in general way, gradeless and uniformly-priced. There are regional differences of the processing methods on Coptidis Rhizoma, which needs unified research and development of relevant standard operating procedures to ensure the quality of medicine, urgently. Coptidis Rhizoma product specifications and the intrinsic quality-grade correlation need to be further improved, which could provide a more reliable standard for quality at competitive prices, and it is recommended that "medicinal commercial specification and grade standard" content be increased into the Herbs part of Chinese Pharmacopoeia.

Background The situation of zonule is very important for determining the cataract surgery.Ultrasound biomicroscopy (UBM) is an important method to observe the situation of zonule before cataract surgery.Objective This study was to evaluate the accuracy and clinical significance of observing the zonule of cataract patients by UBM.Methods A series cases-observational study was performed.One hundred and thirty eyes of 130 cataract patients who were to receive extracapsular cataract enucleation were enrolled in Tianjin Eye Hospital from January to June 2015,including 59 eyes with cataract associated with primary angle-closure glaucoma (PACG) and 71 eyes with traumatic cataract.UBM examination was carried out before surgery,and the abnormalities of zonule were recorded and compared between UBM and surgery findings.This study was approved by the Ethic Committee of Tianjin Eye Hospital and informed consent was obtained from all subjects.Results A large space between lens and cilliary was exhibited and the echo of zonule was clear on the UBM image in the eyes with traumatic cataract.The typical anatomic findings of the anterior eye segment were displayed,and lens equator came into contact with cilliary on the UBM image,and the echo of zonule was blurry in the eyes with cataract associated with PACG.The eye number of abnormal zonule was consistent between UBM and surgery findings (Kappa=O.952),and no significant difference in the eye number of abnormal zonule between UBM and surgery findings (P =0.250).In 75 zonule abnormal eyes diagnosed by both UBM and surgery findings,zonule abnormal range could not be compared in 1 eye (1/130,0.77％),and exactly consistent in 8 eyes (8/130,6.15％) between the two methods.The difference of zonule abnormal range between the two methods was 1 clock in 35 eyes (35/130,26.92％),and 2 clock in 27 eyes (27/130,20.77％),3 clock in 4 eyes (4/130,3.08％).In 74 zonule abnormal eyes,the mean difference of zonule abnormal meridian between the two methods was (1.36 ± 1.29) clock,an those in 28 traumatic cataract eyes and 36 cataract with PACG eyes were (1.14±1.10) clock and (1.64-± 1.48) clock,respectively.Conclusions UBM is able to observe zonule accurately,the observation effectiveness of UBM for traumatic cataract is better than that of cataract combined with PACG.These results are of clinical valueable for surgical strategy of cataract and prediction of surgical complications.

The volatile components of roots and stems of Zanthoxylum nitidum were investigated by supercritical fluid carbon dioxide extraction (SFE-CO2) and gas chromatography-mass spectrometry(GC-MS). Thirty-one and fifty-one compounds were identified in the supercritical extracts from roots and stems of Z. nitidum, respectively, and total twenty-seven compounds were the common constituents. Among them, the major constituents in root and stem supercritical extracts were spathulenol (18.49 and 26.18%), n-hexadecanoic acid (14.24% and 12.79%), ar-tumerone (6.95% and 8.88%), oleic acid (8.39% and 5.71%) and hexanoic acid (4.39% and 7.78%). The in-vitro MTT assay showed that the volatile components of roots and stems of Z. nitidum did not exhibited any cytotoxic activity against human cancer Huh-7 and normal IEC-6 cells. These results indicated the same nature of the volatile constituents in the root and stem of Z. nitidum. This investigation may provide further evidence for expansion of medicinal parts of Z. nitidum.
