Objective:To analyze the analgesic effectiveness of dezocine after laparoscopic cholecystectomy. Methods: Totally 80 patients with laparoscopic cholecystectomy were randomly divided into the observation group and the control group. The control group was given tramadol 0. 2 mg·kg-1 for anesthetize, the observation group was given dezocine 0. 1 mg·kg-1 analgesia. Conducted according to a simgle drug additional pain status of the patient. After the surgery, the time of surgery, VAS and BCS pain condition score of the pa-tients were analyzed and compared, and the incidence of adverse reactions of the two groups were recorded. Results:After the surgery, the operation time, opening eyes, awaking time and extubation time showed no significant difference in the two groups (P>0. 05). VAS scores of the observation group in 30min, 1h, 2h and 6h after the surgery were significantly lower than those of the control group, and BCS score was significantly higher than that of the control group (P<0. 05). The incidence of adverse reactions in the observation group was significantly lower than that in the control group (χ2 =4. 020 5,P=0. 045 0). Conclusion:The analgesic effect of dezocine after lap-aroscopic cholecystectomy is promising, which can significantly alleviate the pain after the operation and is worthy of wider application.

ObjectiveTo evaluate prognostic factors affecting local tumor progression after radiofrequency ablation (RFA) of hepatocellular carcinoma (HCC).MethodsA total of 246 HCC patients (343 lesions) underwent RFA treatment in our department and were enrolled into this study.The average tumor size was 3.7 cm ( range 0.9 ～ 3.7 cm).Regular follow-up with enhanced CT was performed to evalutate the treatment results.Kaplan-Meier model and log-rank test were used in univariate analysis and COX regression model was used in multivariate analysis to identify risk factors for local tumor progression.ResultsThe local tumor progression rate was 11.4％ (39/343 lesions),and the average time from initial RFA to local tumor progression was 12.0 months.Univariate analysis indicated tumor size ( P ＜0.001 ),close to intrahepatic vessels ( P ＜0.001),tumor boundary ( P =0.020),pathological grade( P =0.010) and CEUS before RFA ( P =0.001) as risk factors for local progression.The following factors were identified as independent prognostic factors for local tumor progression by multivariate model:tumor size (P ＜ 0.001),isolated or close to intrahepatic vessels( P ＜0.001) and CEUS before RFA(P =0.018).ConclusionsTumor size,CEUS before RFA and close to intrahepatic vessels are the most important factors for local progression after RFA.Being awaring of possible risk factors for local tumor progression may increase the treatment efficacy and help to promote the use of RFA technique.

A total of 55 children aged under 14 years with cholecystolithiasis were treated at our hospital between January 2005 to December 2011.Their clinical data were collected and analyzed.The etiologies included pseudolithiasis (n =36),chronic hemolytic disease (n =2),obesity (n =9) and unknown (n =8).Among 50 cases on conservative treatment,42 cases were cured.Four cases underwent laparoscopic cholecystectomy.During a follow-up period of 2-4 years,there was no occurrence of significant complications.The removal of gallbladder stone was performed via laparoscopy plus choledochoscope in 1 case.There was no recurrence during a follow-up period of 2 years.Ceftriaxone sodium and obesity were the major cause of pediatric cholecystolithiasis.A proper selection of treatment regimens should be based upon the considerations of etiologies and symptoms.

Coumarins are a group of important natural compounds, and have been found to have multi-biological activities such as anti-HIV, anti-tumor, anti-hypertension, anti-arrhythmia, anti-osteoporosis, assuaging pain, preventing asthma and antisepsis. One of which is its anti-tumor effect and that is a research focus on. Therefore, we believe that it is necessaryto carry out further studies on the effect of coumarins compounds in anti-tumor. Investigation should emphasize on improving techniques for extraction and separation, searching the effective precursory compound, and synthesizing and screening out courmarin derivatives with high activity and low toxicity. Here the recent research progress in anti-tumor effect of coumarins compounds is reviewed.

Objective To investigate the effects of traditional Chinese medicine on the differentiation of mesenchymal stem cells(MSC)to osteoblasts.Methods Six male Beagle dogs weighed 10-15 kg each were divided into three groups,group A:medicine serum group,group B:non-medicine serum group and group C:bovine serum group.The serum of group A was obtained from the femoral artery of 2 Beagle dogs drinking equivalent dose of traditional Chinese medicine according to body surface area for 7 continuous days.The serum of group B was collected from the femoral artery of 2 Beagle dogs fed with equal volume of normal saline for 7 days.The serum of group C was fetal bovine serum.The tibia marrow was harvested from another 2 Beagle dogs and MSC were isolated and purified by density gradient centrifugation.MSC were cultured in DMEM solution with fetal bovine serum. After MSC were digested by trypsin.MSC were cultured in DMEM solution wuth the osteogeneic inducer,which contained dexamethasone,antiscorbutic and β-glycerophosphate.Morphological and histological changes of the MSC were observed under an inverted microscope.Alizarin monosulfonate and nitric acid argentum staining was performed to observe the calcium deposition.MSC were curtured in DMED solution with medicine serum(group A),non-medicine serum(group B)and bovine serum(group C)respectively.The growth curve was detected by the methyl thiazoly tetrazolium (MTT). The alkaline phosphatase(ALP) activities were detected to observe the differentiation of MSC. Results The original MSC were observed as fibroblast-like cell shapes. After the osteogeneic inducer was added, MSC were polygon cells with a few polyprocess. Calcium deposition appeared during 10-14 days and alizarin monosulfonate and Von Kossa staining presented positive. MTT results showed that the number of adherent cells of group A was more than that of group B and that of group C significantly after 6 days (P <0. 05). ALP detection proved that ALP activity of group A was more than that of group B and that of group C significantly after 5 days ( P < 0. 05 ). Conclusions The traditional Chinese medicine promotes the differentiation of MSC to osteoblasts and osteogenesis.

Double aortic arch with an atretic left arch distal to the origin of left subclavian artery was diagnosed with multi-detector row computed tomography (MDCT) in two children with dysphagia. This rare type of complete vascular ring is clinically important because it may be confused with right aortic arch in mirror imaging. Anatomic details of this rare type of complete vascular ring demonstrated on MDCT facilitated appropriate surgical treatment.

Background：Global Handwashing Day (GHD) is a handwashing promotion campaign organized by the Global Public-Private Partnership of Handwashing with Soap. In China, it has been promoted by the Chinese public health authorities, international organizations and multinational corporations through various channels including social media such as Sina Weibo, the leading Chinese microblogging site similar to Twitter. The objective of this study is to qualitatively assess Chinese social media users’ reactions to a health promotion campaign using Global Handwashing Day (GHD) 2012 as an example.Methods：We conducted a qualitative content analysis of 552 Weibo posts generated on GHD 2012 by Weibo users with 1000 or more followers with the Chinese keyword for “handwashing.” We categorized the Weibo posts into groups by keywords that frequently appeared in the data set. These groups were either exact reposts of an original post, or they conveyed similar information.Results：We observed the interconnections between traditional media and social media in handwashing promotion. Social media were found to serve as amplifiers of contents provided by traditional media. We observed the contextualization of global hygiene messages in a unique national social media market in China.Discussion：Our study showed that social media and traditional media are two interconnected arms of the GHD campaign in China. Our analysis demonstrated that public health campaigns in China can be evaluated using social media data. The themes and topics identified in this study will help public health practitioners evaluate future social media handwashing promotion campaigns.

OBJECTIVETo demonstrate the changes of resting energy expenditure (REE), substrate metabolism and body composition in cancer patients.

METHODSFrom September 2004 to March 2008, REE, carbohydrate oxidation (CO) and fat oxidation (FO) in 936 cancer patients and 840 control subjects were measured by indirect calorimetry. Bioelectrical impedance appliance was applied to assess intracellular fluid, extracellular fluid, fat mass (FM) and fat free mass (FFM) in the two groups.

RESULTSNo difference in REE was found between the cancer patients and non-cancer patients [(1452.2 +/- 196.4) kcal/d vs. (1429.5 +/- 182.6) kcal/d, P = 0.136]. But REE/FFM and REE/pREE were elevated in cancer patients than in controls (all P < 0.05). Of the cancer patients, 48.6% were hypermetabolic, 42.9% normal and 8.5% hypometabolic, while those were 22.5%, 58.5% and 19.0% in controls. Cancer patients had higher FO [(77.8 +/- 11.3) g/min vs. (67.1 +/- 12.1) g/min, P = 0.000], lower CO and npRQ [(68.7 +/- 10.5) g/min vs. (88.8 +/- 12.1) g/min, P = 0.000; 0.782 +/- 0.012 vs. 0.810 +/- 0.014, P = 0.000]. Cancer patients exhibited lower FM and FFM [(14.9 +/- 4.5) kg vs. (18.4 +/- 5.2) kg, P = 0.000; (44.4 +/- 7.2) kg vs. (46.1 +/- 8.1) kg, P = 0.008].

CONCLUSIONSElevated REE is common in cancer patients. Substrate metabolism of the cancer patients features in increased FO, decreased CO and npRQ, which is correlated with the elevated REE. FM and FFM loses in proportion in cancer patients.
