To explore the analgesic effect of propofol combine with dezocine after painless abortion and the influence on stress hormone and hemodynamics of the patients. Methods:Totally 126 cases of patients with painless abortion in our hospital from March 2013 to March 2014 were randomly divided into the observation group and the control group with 63 ones in each. The observa-tion group was anesthetized with propofol combine with dezocine, while the control group was anesthetized only by propofol. The dosage of propofol, anesthesia effect and postoperative recovery of the patients in the two groups were compared, and the level of stress hor-mones and hemodynamic parameters before and after the surgery were also compared. Results: Compared with that in the control group, the dosage of dezocine and the score of VAS after the surgery was significantly reduced in the observation group with obviously better anesthesia effect, and the differences had statistical significance (P<0. 05). The level of Cor, NE and ACTH was significantly improved, and the level of A-I and A-II was reduced significantly in the observation group, and compared with that in the control group, the differences showed statistical significance(P<0. 05). Compared with those that in the control group, the levels of SBP, DBP and SpO2 were improved significantly and the level of HR was reduced significantly in the observation group during and after the surgery, and the differences showed statistical significance (P<0. 05). The incidence of adverse drug reactions in the observation group was significantly lower than that in the control group, and the difference had statistical significance (P<0. 05). Conclusion:Propofol combine with dezocine for the surgery of painless abortion can reduce the dosage of dezocine, improve the anesthesia effect and reduce the harem pain with lower stress hormone fluctuation, hemodynamic effect and incidence of adverse reactions.

AIM:To investigate the effect of hydrogen sulfide(H2S)donor(NAHS)on oxidative stress of adriamycin-induced dilated cardiomyopathy rats.METHODS:Weight-matched adult male Wistar rats were randomly divided into 5 groups as follows:(1)ADR group(n=12),in which 2.5 mg/kg of adriamycin was injected intraperitoneally once a week for 10 weeks(total dose of 25 mg/kg).(2)ADR+small-dose NaHS group(n=12),in which the dosage and the use of adriamycin were as mentioned above,while NaHS solution was injected to rats at a dosage of 2.8 ?mol?kg-1?d-1 at the same time.(3)ADR + large-dose NaHS group(n=12),in which the dosage and the use of adriamycin were as mentioned above,while NaHS solution was injected to rats at a dosage of 14 ?mol?kg-1?d-1 at the same time.(4)Control group(n=9),in which an equivalent volume of physiological saline was administered weekly for a total of 10 weeks.(5)NaHS group(n=9),in which 14 ?mol/kg of NaHS solution was injected to rats intraperitonealy once a week for 10 weeks.Hemodynamic and echocardiographic measurements were obtained 10 weeks after the treatment.Meanwhile,H2S and malondialdehyde(MDA)concentrations,the activities of superoxide dismutase(SOD)and glutathione peroxidase(GSH-Px)in serum and myocardial tissues were evaluated,respectively.RESULTS:The cardiac functions in the group of ADR rats depressed obviously.H2S concentrations,SOD and GSH-Px activities in serum and myocardial tissues of ADR group rats were all significantly decreased as compared with those in the control group(P

Objective This study was designed to investigate the importance of H2S in rats with adriamycin-induced dilated cardiomyopathy.Methods Weight-matched adult male Wistar rats were randomly divided into 5 groups as follows:(1)the ADR group(n=12)where adriamycin(2.5 mg/kg)was given once a week;(2)ADR + small-dose NaHS group(n=12)where NaHS solution [2.8 ?mol/(kg?d)] was given;(3)ADR+large-dose NaHS group(n=12)where NaHS solution [14 ?mol/(kg?d)] was given;(4)the control group(n=9)where physiological saline was administered instead of adriamycin.(5)NaHS group(n=9)where NaHS solution [14 ?mol/(kg?d)]was given.Hemodynamic and echocardiographic measurements were carried out after treatment.Histological examination was implemented at the 10th week after the rats were sacrificed.Meanwhile,H2S concentrations in serum and myocardial tissues were evaluated by modified sulfide electrode method.Results The heart function of ADR rats decreased obviously.Pathological examination demonstrated that characteristics consistentwith cardiomyopathy were found in ADR group.H2S concentrations in serum and myocardial tissues of the rats in ADR group were both significantly decreased as compared with those in the control group(both P

Objective To investigate the clinical features, prognosis and risk factors of patients of acquired immunodeficiency syndrome (AIDS) complicated with cryptococcal meningitis (CM). Methods Totally 26 patients of AIDS with CM who were hospitalized in the No. 8th People's Hospital of Guangzhou were enrolled in this study. The clinical data including diagnosis,experimental and etiological test,treatments and prognosis from all the patients were analyzed retrospectively. The results of cerebrospinal fluid routine test and CD4+ T lymphocyte were compared with those of AIDS patients complicated with tuberculous meningitis. Results Among the 26 patients enrolled in the study, the positive rate of cerebrospinal fluid india ink smear or Crypotococcus neoforrnans euhure was 84.6%. The most common symptoms were fever, headache and meningeal irritation sign. The average CD4+ lymphocyte count was 17.83 × 106/L, which was statistically different from that of tuberculous meningitis patients. All the patients showed concomitant multiple organ infections. The mortality rate was as high as 42.3%. At the end of therapy, the cell counts in the eerebrospinal fluid were remarkably higher in the patients with unfavorable prognosis compared to the patients with good prognosis, which was statistically different. Conclusions CD4+ lymphocyte count is an important marker for differentiating CM from tuberculous meningitis in AIDS patients. The results of cerebrospinal fluid routine test can predict the prognosis.

Objective To analyze the clinical characteristics and treatment strategy of ankle supination fracture in children.Methods From January 2012 through July 2014,89 children were treated at our department for ankle fracture caused by supination sprain according to their medical history,physical examination,X-ray films and CT three-dimensional reconstruction of the ankle.Appropriate protocols were applied on the basis of Lauge-Hansen classification,type and displacement of their fractures.Of them,52 belonged to the supination-adduction type (the extramalleolus fracture was of Odgen type Ⅶ in 51 children whose epiphyseal plate of distal fibula had not been closed),35 to the supination-extorsion type (32 cases had tri-plane fracture and 3 Tillaux fracture),and the remaining 2 did not fit the Lauge-Hansen classification.Surgical treatment was applied in 32 cases and conservative treatment in 57 ones.Results All the children received outpatient follow-up from 12 to 24 months(mean,18 months).No bone nonunion,osteoarthritis,or fracture malunion was found.The American Orthopaedic Foot & Ankle Society scores averaged 92 points (range,from 88 to 100 points) at the last follow-ups.Conclusions In children whose epiphyseal plate is nearly closed,supination-adduction sprain likely causes an extramalleolus fracture of Salter-Harris type Ⅰ or type Ⅱ,but in children whose epiphyseal plate is unclosed,an epiphyseal fracture of Odgen type Ⅶ is inclined to happen.A Tillaux fracture or tri-plane fracture at the level of distal tibiofibular syndesmosis results often from supination-extorsion sprain in children.For fractures involving epiphysis or epiphyseal plate,anatomical reduction and proper fixation are critical to functional recovery and reducing complications.

Objective To improve the technology of retroperitoneal laparoscopic living donor nephrectomy and observe its clinical effect.Methods Forty-one cases of living donors subject to nephrectomy by the new retroperitoneal laparoscopic technique from July 2009 to June 2012 were retrospectively.The new technique was modified as follows: (1) Alternate use of blunt dissection,sharp dissection and harmonic scalpel; (2) After separation of renal vein,artery and ureter,a 5-6 cm incision parallel to rectus abdominis from Trocar was made in order to put a hand inside retroperitoneum; (3) A biopsy of the kidney was made from Trocar with the help of a hand for holding the kidney; (4) Pulling the kidney with a proper strength and blocking renal artery and renal vein with Hem-o-lock,then cutting off them and taking out the kidney.Results Forty-one cases of live donors subject to nephrectomy were operated on successfully,and were not converted to open operation.The operative time was 65-130 min (mean 85 min).The warm ischemia time was 58-110 s (average 78 s).Living donor kidney artery length was 2.1-3.7 cm (average 2.9 cm).Living donor kidney vein length was 2.5-4.1 cm (average 3.5 cm).Blood loss was 15-80 ml (average 28 ml).Hospital stay after surgery was 4-7 days (average 4.8 days).All biopsy specimens were achieved from 41 cases.None suffered from complications except two cases of perilymphorrhea.Forty-one recipients recovered well after renal transplantation.Conclusion The improved retroperitoneal laparoscopic living donor nephrectomy is considered to be safe,effective and feasible.It is a good way to protect renal function and reduce injury.

Objective To evaluate the expression of transient receptor potential melastatin 7(TRPM7)in cholangiocarcinoma and its correlation with prognosis.Methods The expressions of TRPM7 were detected by SP immunohistochemical in 49 cases of cholangiocarcinoma,7 cases of benign bile duct lesions and 36 cases of adjacent histologically noncancerous bile duct tissues,and to analysis its relationship with the clinical pathological characteristics of cholangiocarcinoma.Results The positive expression rate of TRPM7 in cholangiocarcinoma was 77.6%(38/49),which was higher than that in benign bile duct lesions(0,0/7)and adjacent his-tologically noncancerous bile duct tissues(2.8%,1/36),the difference was statistically significant(P <0.05).The positive expres-sion of TRPM7 in cholangiocarcinoma was correlated with the TNM stage of tumor,lymph node metastasis and organ metastasis (P <0.05),but not related to patients′age,gender,site,differentiation and hepatitis(P >0.05).Kaplan-Meier analysis showed that increased expression of TRPM7 was associated with shorted overall survival (P <0.05).Cox regression analysis showed that the expression level of TRPM7 was significantly associated with prognosis and an independent risk factor for prognosis(P <0.05 ). Conclusion TRPM7 plays an important role in the tumorigenesis progression,invasion,and metastasis of cholangiocarcinoma,and is an important factor for prognosis in patients with cholangiocarcinoma.

The aim of this study was to observe the difference in respect to the leukocyte reduction efficiency and quality of fresh-frozen plasma (FFP) from filtered whole blood between two types of in-line filters wherein only filter materials were surface modified by the two methods respectively. Whole blood was kept in refrigerator and filtered within 6 h of collection at ambient temperature. Samples were taken pre- and post filtration for analysis of WBC numbers, coagulation factors and complement activation (n = 8 for each type of filter). All filtered units contained < 2. 5 x 10(6) residual leucocytes. RBCs recovery was over 93%. No significant difference between group A and B was seen. But group B appeared to take longer time for filtration than did group A (9'29" vs. 8'01"). Neither group A nor group B showed statistically significant losses of total protein, album, IgG, IgM, fibrin, factors VIII, IX, vWF and C3 (P > 0.05). Factor V, XI and AT-III decreased significantly in two group filters. Group B showed more significant losses of IgA content and factor V activity than did group A, which appeared to be related to the difference in surface character between group A and group B filters. These two types of filters could remove leukocytes effectively, and no significant changes were observed in the quality of FFP from the filtered whole blood. It is presumed that the filter material with better bio-compatibility will give a high recovery of plasma protein and coagulation factors after filtration.

The most difficult field in gene therapy is that vector system should offer both a means of successful transfection and a maximum of safety for the patient. Viral vectors and plasmid vectors are traditional vectors; they may cause unwanted immunological side effects resulting from the expression of nontherapeutic genes. Our aim is to develop a new general gene therapy vector which is suggested to be called as Micro-Linear Vector. The gene expression cassette is capped by our designed cap, including promoter, enhancer, objective gene, and RNA-stabilizing sequence, so it can defend the exnuclease in the eukaryotic cell, at the same time, DNA not encoding the objective gene is reduced to a minimum. The GFP gene is separated from the pEGFP-N3 plasmid, and acts as a reporter gene to construct the Micro-Linear Vector, then both the new vector and the plasmid are transfected to cells, the results are tested by fluorescence microscope and flow cytometry. The results show that the Micro-Linear Vector has a high effective of transfection and safety in 293, 3T3, CNE2 and B95-8 cell lines, at the same time it is less toxicity than the plasmid. We can get the rudiments of conclusion that Micro-Linear Vector has high effection of the transfection and more safety than tradition plasmid in eukaryotic cell.
