Objective To investigate the risk factors of post-operative cardiovascular or pulmonary complications in patients with gastrointestinal tumor. MethodsThe data of 352 cases with gastrointestinal tumor were analyzed retrospectively. These patients were divided into the two groups based on with or without cardiovascular or pulmonary complications. Seven relative factors including the patients' age, sex, smoking, duration of surgery, pulmonary function, ECG, UCG, and relationship between these factors and the incidence of post-operative cardiovascular or pulmonary complications were analyzed.ResultsForty-two cases occourred cardiovascular or pulmonary complications in 352 patients. The mean age and surgery duration were (61.2±7.9) years and (3.0±0.9) hours in patients with cardiovascular or pulmonary complications, and (53.5±4.6) years and (2.7±0.7) hours in patients without cardiovascular or pulmonary complications respectively. There was a significant difference between the two groups ( P<0.05). The patients with abnormal FEV1%, FEV1/FVC%, MVV% and cardiac function before operation had higher risk for post-operative cardiopulmonary complications ( P<0.05).ConclusionAge, duration of surgery and cardiac and pulmonary dysfunction may be risk factors of cardiovascular or pulmonary complications after gastrointestinal surgery.

OBJECTIVETo study whether the analgesis of oxymatrine (OMT) affects N-type voltage-gated calcium channels (VGCCs).

METHODSTotally 45 mice were randomly divided into the sham-operation group, the model group [established by partial sciatic nerve ligation (PSNL)] , and the OMT treatment group according to random digit table, 15 in each group. The dorsal root ganglions (DRG) were separated in PSNL pain model mice. Intracellular calcium concentration ([Ca2+]i) was determined with Fluo-3 AM immunofluorescent probe in cultured DRG neurons. Different protein expression levels of N-type (Cav2. 2) and L-type ( Cav1. 3) among VGCCs from brain and DRG tissues were detected with Western blot.

RESULTSCompared with the sham-operation group, [Ca2+]i, increased in cultured DRG neurons (P <0. 05) , protein expression levels of Cav2. 2 in the brain tissue increased (P <0. 05), protein expression levels of Cav2. 2 in DRG tissues decreased in the model group (P <0. 01). Compared with the model group, [Ca2+]i, decreased in cultured DRG neurons (P < 0. 05), protein expression levels of Cav2. 2 in the brain tissue decreased (P <0. 01), protein expression levels of Cav2. 2 in DRG tissues increased in the OMT treatment group (P <0. 01). There was no statistical difference in Cav1. 3 expressions in cultured DRG neurons and the brain (P >0. 05).

CONCLUSIONAnalgesic effect of OMT might be related to Cav2. 2 channel mediated calcium ion flux.

OBJECTIVETo explore the analgesia of oxymatrine (OMT) affecting high voltage-dependent calcium channels (HVDCCs) and GABA release under neuropathic pain condition.

METHODSTotally 66 C57BL/6 mice were randomly divided into the sham-operation group, the model group, and the OMT group, 22 in each group. Neuropathic pain models were established by partial sciatic nerve ligation (PSNL). Hind paw plantar mechanical response threshold (MWT) was measured by up-and-down method with Von-Frey filament. mRNA expression of HVDCCs in brains and spinal cords was detected with Real-time PCR and concentration of GABA was determined using ELISA kit.

RESULTSCompared with day 0, the left hind paw MWTwas decreased on day 7, 10, and 14 in the model group (P < 0.05). Compared with the sham-operation group, the left hind paw MWT was significantly reduced in the model group on day 7 (P < 0.05). The MWT of PSNL ipsilateral hind paw was decreased on day 7 before OMT administration, when compared with day 0 (P < 0.05), and increased after OMT administration (P < 0.05). Compared with the sham-operation group, mRNA levels of Cav1.2, Cav1.3, Cav2.1, and Cav2.3 in brain tissues were increased and those of Cav2.2 were decreased significantly in the model group (P < 0.05). In spinal cord tissues, mRNA levels of Cav1.2 and Cav1.3 were increased, but those of Cav2.1, Cav2.2, and Cav2. 3 were decreased significantly in the model group, when compared with those of the sham-operation group (P < 0.05). Compared with the model group, mRNA levels of Cavl.2, Cavl.3, Cav2.1, and Cav2. 3 in brain tissues were decreased, and those of Cav2.2 were increased significantly in the OMT group (P < 0.05). In spinal cord tissues of the OMT group, mRNA levels of Cav1.3 decreased and those of Cav2.1, Cav2.2, and Cav2.3 increased significantly with statistical difference, when compared with those of the model group (P < 0.05). Compared with the sham-operation group, GABA levels in brain tissues decreased in the model group (P < 0.05). Compared with the model group, GABA levels in brain tissues increased in the OMT group (P < 0.05). There was no statistical difference in GABA levels of spinal cord tissues among these groups (P > 0.05).

CONCLUSIONSOMT had analgesic effect on neuropathic pain, which might be probably related to HVDDCs. Cav2.2 might directly affect GABA release.

Objective To compare the therapeutic effect of angiotensin Ⅱ antagonist (Valsartan)and angiotension-converting enzyme inhibitor (Captopril) for the improvement of left ventricular systolic function(LVSF) after acute myocardial infarction (AMI) at anterior wall. Methods A total of 75 patients with initial AMI at anterior wall were enlisted in the study. Patients were divided randomly into three groups: control group (n = 15), Captopril treated (n =30), and Valsartan treated (n =30). At 1 week and 28 weeks post AMI, the LVSF and left ventricular regional ejection fraction (LrEF) were measured by equilibrium radionuclide angiography (ERNA). The t-test was used to compare the dada. Results ( 1 ) At 28 weeks, left ventricular ejection fraction (LVEF) and left ventricular peak ejection rate (LPER) in Valsartan treated group were significantly increased as compared with those of control: ( 59.4 ± 8.6 ) % vs (44.9 ± 8.4)%, t = 3.87, P ＜ 0.01 for LVEF; (3.89 ± 1.01 ) end-diastolic volume (EDV)/s vs (2.84 ±1.05) EDV/s, t= 4.16, P ＜ 0.01 for LPER). The left ventricular time to peak ejection rate (LTPER) in Valsartan treated group was significantly decreased ( ( 116 ± 16 )ms vs ( 137 ±20) ms, t =2.16, P ＜ 0.05 ) as compared with control. (2)Compared with 1-week, 28-week Valsartan treated group had a significant increase inLrEF2, LrEF4, LrEF5, LrEF6: (71.6±18.8)% vs (57.0±11.4)%, t=2.11, P＜0.05;(78.1 ±16.8)% vs (68.9±21.0)%, t =2.06, P＜0.05; (70.5±16.9)% vs (59.9 ±23.4)%, t=1.99, P ＜ 0.05; and (58.1 ± 9.0) % vs (46.0 ± 18.9) %, t = 2.43, P ＜ 0.05, respectively. Conclusions Valsartan and Captopril are effective for the improvement of LVEF after AMI at anterior wall. The effects of the two drugs are similar.

Objective To explore the curative effect and prevention of complications of emergency laparoscopic cholecystectomy(LC) for acute cholecystitis.Methods The clinical data of 1 278 patients with acute cholecystitis who were treated with emergency laparoscopic cholecystectomy from July 2004 to July 2010 in our haspital were collected and analyzed retrospectively.Among these patients,471 cases had mild acute cholecystitis,720 cases had acute suppurative cholecystitis and 87 cases had acute gangrenous cholecystitis.The impaction of stones in the neck of gallbladder was present in 823 cases.The impaction of stones in the cystic duct was present in 157 cases.In 96 cases emergency operation was performed within 48 hours after the synptoms occurred,in 799 cases operation was performed from 48 to 72 hours,and in 383 cases operation was undertaken after 72 hours.Results The mean operation time was 40min(20-90 min) and the mean blood loss was 80ml(20-300 mL).Early postoperative fever(38.0～39.5℃) developed in 375 cases.Temporary jaundice was found in 108 cases.Bile leakage occurred in 17 cases.No LC cases were converted to open cholecystectomy.No cases were complicated with bile duct injury and there was no mortality.Conclusions Emergency laparoscopic cholecystectomy for acute cholecystitis is difficult.The probable complication rate is quite high.Severe complications can be avoided with skillful surgical technique and rich operative experience.Acute cholecystitis is not a contraindication for emergency laparoscopic cholecystectomy.

The Monascus mutant with high yield of yellow pigment was obtained by using conventional relevant mutation techniques, e.g., treating with physical mutagens(such as UV light) and chemical sub- stances (such as N-methyl-N'-nitro-N-nitrosoguanidine). The yellow pigment was scanned from 300 nm to 600 nm with UV spectrometer, the maximal absorption was determined at 410 nm. The growth characteristic of Monascus mutant is stable, the yellow pigment value and colour hue in liquid fermentation can reach 100 U/mL and 3.5 respectively. The yellow pigment is stable from pH 3 to pH 8, but the precipitation appeared as the pH of the pigment solution lower than 3.
