Objective To compare the clinical efficacy between laparoscopy and open cholecystectomy for patients of acute calculous cholecystitis. Methods Fifty patients of acute cholecystitis from February 2014 to February 2017 were divided into control group treated with open cholecystectomy and observation group with laparoscopic cholecystectomy;a retrospective analysis was conducted to compare time of resuming peristaltic sound ,postoperative 24h VAS score and hospitalization time. Results There were shorter time of resuming peristaltic sound,higher postoperative 24 h VAS score and shorter hospitalization time in observation group when compared with those in control group (P < 0.05). Conclusions For patients of acute calculous cholecystitis , laparoscopic cholecystectomy,is conducive to shortening patient′s recovery time,alleviating patients′ pain signifi-cantly and decreasing the incidence of complication.

Objective To clone and sequence human OPRMI-EXON1, mark it by way of nonisotope-biotin-label, and prepare its probe to study the expression and function of human OPRMI-EXON1. Methods The target gene fragment was amplified by polymerase chain reaction (PCR), and connected to the pGEM-T vector plasmid, then recombined and cloned in competent cell. After that, it was identified by cutting with restriction endonucleases and gene sequence. Finally, we marked it and prepared its probe by nonisotope-biotin-label technique. Results It was demonstrated that the target gene length (2.2kb) amplified by polymerase chain reaction had the same size with the reckoned size in theory and had the same sequence with that of NCBI database. The probe which was used to study the opioid receptor gene was successfully prepared. Conclusion The human OPRMI-EXON1 can be successfully cloned and the probe successfully prepared from the genome, which creates a favorable basis for further research of the morphine-related genes and the expression of their dependence.

Molecular biology is the fundamental course of life science,and its experimental teaching is difficult to offer due to its long process and need of expensive equipments.Virtual laboratory platform is an important approach for practice teaching in recent years.This article discussed the advantages and requirements,provided the experience of its applying at our university,and suggested that virtual laboratory platform can play a key role in molecular biology experimental teaching.

Objective To investigate the effects of 3％ and 7.5％ hypertonic saline (HS) on hemorrhagic shock patients in Emergency Department.Methods From December 2008 to February 2012,patients older than 15 years with severe trauma and systolic blood pressure (SBP) ≤70 mmHg or 70 to 90 mmHg with heart rate≥ 108 per minute were divided into three groups randomly (random number).Group A:patients treated with 3％ hypertonic saline (HS) 300 mL + lactated Ringer' s solutions (LRS).Group B:patients treated with 7.5％ HS 300 mL + LRS.Group C:patients treated with LRS.The mean arterial pressure (MAP),blood pressure (BP),heart rate (HR) were recorded before infusion and at 10,30,45,60 minutes successively after infusion.Incidence of complications and mortality rates were compared between groups.Results Atotal of 148 patients were enrolled in this study.Compared with LRS grouop,MAP was restored more promptly and maintained persistently in 3％ HS group and 7.5％ HS group,and the total volume of fluid infused was decreased to almost 50％ of LRS in the first 1 hour.No significant differences in MAP levels were observed between group A and B except 30 minutes after infusion.Single bolus of 7.5％ HS infusion resulted in increased of HR to mean 127 beats per minute at 10 minutesafter fluid resuscitation.Higher incidence of arrhythmia and transient hypotension occurred in 7.5％ HS group.There were no statistical differences of changes of electrolytic indices,mortality rates,incidences of ARDS and MODS among three groups.Conclusions Resuscitation with 3％ HS provide similar benefits and lower risk of complications compared with 7.5％ HS and LRS.This study demonstrates the practicability and safety of 3％ HS for fluid resuscitation of patients with hypovolemic shock.

Objective To study the mRNA expressions of Toll-like receptor (TLR) 2 and 4 in peripheral blood mononuclear cells (PBMCs) of patients with leprosy. Methods SYBR Green fluorescence quantitative RT-PCR was conducted to detect the mRNA expressions of TLR2 and 4 in PBMCs from 30 patients with cured leprosy, 30 patients with active leprosy and 30 normal human controls. Results The expression of TLR2 mRNA in patients with active leprosy was significantly higher than that in those with cured leprosy and in controls (both P ＜ 0.01 ), but there was no significant difference between the latter two groups (P ＞ 0.05). The expression of TLR4 mRNA was of no significant difference between patients with active leprosy and those with cured leprosy orthe controls (both P＞ 0.05). Conclusion The expression of TLR2 mRNA is decreased in PBMCs from leprosy patients, suggesting that TLR2 may be a specific recognition receptor in patients with leprosy.

Objective To evaluate the effect of recombinant human erythropoietin (rHuEPO) on lung injury induced by hepatic ischemia-reperfusion (I/R) in rats.Methods Sixty healthy male SpragueDawley rats, aged 6-8 weeks, weighing 220-280 g, were randomly divided into 3 groups (n=20 each) using a random number table: sham operation group (group S) , hepatic I/R group (group I/R), and rHuEPO group (group E).I/R and E groups underwent I/R of 70 percent of the liver.The rHuEPO 4 000 U/kg was injected intraperitoneally at 24 h before I/R in group E, while the equal volume of normal saline was given in S and I/R groups.The rats were sacrificed at 3 h of reperfusion, and lungs were removed and cut into sections which were stained with haematoxylin and eosin and examined under light microscope.Wet to dry lung weight ratio (W/D ratio) was calculated.The expression of heme oxygenase-1 (HO-1) and inducible nitric oxide synthase (iNOS) in lung tissues was determined by immunohistochemistry.The content of malondialdehyde (MDA), and activities of superoxide dismutase (SOD) and myeloperoxidase (MPO) in lung tissues were detected.Results Compared with group S, the W/D ratio, MDA content, and MPO activity were significantly increased, the SOD activity was decreased, the expression of HO-1 and iNOS was up-regulated (P＜0.05) , and the pathological changes of lung tissues were obvious in E and I/R groups.Compared with group I/R, the W/D ratio, MDA content, and MPO activity were significantly decreased, the SOD activity was increased, the expression of HO-1 was up-regulated, the expression of iNOS was down-regulated (P＜0.05) , and the pathological changes of lung tissues were reduced in group E.Conclusion The rHuEPO can alleviate hepatic I/R-induced lung injury in rats, and the mechanism may be related to up-regulated expression of HO-1 and down-regulated expression of iNOS.

Objective To investigate the clinical features, diagnosis and treatments of pelvic abscess with endometriosis. Methods A retrospective analysis was performed on 129 cases of pelvic abscess in Peking Union Medical College Hospital from January 2000 to January 2016. Among them, 34 women with endometriosis were divided into the study group and the others were in the control group. The clinical characteristics, therapeutic regimens and outcomes were compared. Results (1) General conditions:there were no statistic differences between the two groups in age, WBC, serum CA125, intrauterine device in use, pelvic inflammatory disease history;while incidence rates of dysmenorrhea (65%, 22/34) and infertility (21%, 7/34) in the study group were higher than those in the control group (all P<0.05). (2) Clinical manifestations:fever, abdominal pain and pelvic mass were the main symptoms in two groups. The incidence rates of septic shock were 12%(4/34) in the study group and 2%(2/95) in the control group (P<0.05). (3) Treatment:treatment with puncture all failed in the study group (7/7) and surgeries were required. In contrast, there was only 1/19 treatment failure with puncture in the control group. The puncture failure rates were statistically significant (P<0.05). Compared with the study group and the control group, there were significant differences (P<0.05) in the operation time of laparoscopic surgery [(76±41) versus (53±21) minutes] and of laparotomy [(168±58) versus (116±35) minutes], intra-operative blood loss of laparoscopic surgery [(216±296) versus (43±36) ml] and of laparotomy [(448 ± 431) versus (145 ± 24) ml]. Conclusions Pelvic abscess in women with endometriosis is more severe and refractory to antibiotics and puncture treatment. Active surgical intervention is required. Although surgical procedures are often difficult, prognosis is comparatively satisfied.
