Objective To compare effects between laparoscopy and laparotomy for the treament of ovarian endometriosis cysts and to investigate the value of laparoscopy in the treatment of ovarian endometriosis cysts. Methods We retrospectively analyzed 144 cases of ovarian endometriosis cysts,92 of which underwent laparoscopic operations(Laparoscopic Group) and 52 of which received open operations(Open Group).All the cases were followed for 4 months ~ 5 years.Results The operation time,postoperative hospital stay,and intraoperative blood loss were 69?41.8 min,3.5?1.0 d,and 55?12.0 ml in the Laparoscopic Group,respectively,and 137?54.3 min,8.7?3.5 d,and 178?105.9 ml in the Open Group,respectively,with significant differences between the two groups(t=-8.402,-11.048,and-13.350;P=0.000).There was no significant difference in the rate of abdominal pain relief between the Laparoscopic Group(66.0%,35/53) and the Open Group(52.8%,19/36)(?~2=1.580,(P=0.209)).The recurrent rate was 19.6%(18/92) in the Laparoscopic Group and 19.2%(10/52) in the Open Group,without significant difference between the two groups(?~2=0.002,P=0.961). Conclusions Laparoscopic surgery gives similar efficacy to open surgery in the treatment of ovarian endometriosis cysts.Laparoscopic surgery can be used as the first choice in treating ovarian endometriosis cysts because of its minimally invasive characteristics.

OBJECTIVE: To analyze the amount and inflammatory components of the sputum in patients with "disharmony of stomach", including gastroesophageal reflux disease, peptic ulcer and chronic gastritis. METHODS: Sputum production was induced by inspiration of aerosol of 3.5% hypertonic saline with ultrasonic nebulizer, and the total cell count in the sputum was examined. Sputum smear stained with Gimsa was used in differential counting under light microscope. Bacterial culture in the sputum was performed in the usual way. Peak expiratory flow (PEF) was tested to study the airway responsiveness. RESULTS: The amount of sputum, the total cells and eosinophils in the sputum of the patients with "disharmony of stomach" were higher than those of the control. PEF decreased following sputum induction. These parameters returned to control level after treatment with Chinese herbs. Bacterial culture was negative. CONCLUSION: "Disharmony of stomach" can cause the bronchial inflammation (non-infection) characterized by eosinophil increase.

OBJECTIVETo determine the recognition of healthy medical students on deqi after acupuncture, reveal the qualitative and quantitative rules of deqi and understand whether these rules are the factors of the clinical application of acupuncture therapy.

METHODSThe class questionnaires were used for the investigation study on the understanding of deqi after acupuncture at Hegu (LI 4) or Zusanli (ST 36) in 86 healthy students in the clinical medicine class.

RESULTS(1) Deqi was a kind of complicated compound feelings, with many sensation qualities such as distending pain, distension and pain. (2) Deqi was a kind of mild and moderate sensations. In 10-score credit sys tem of Massachusetts General Hospital acupuncture sensation scale (MASS), the scores of distending pain (4.69 +/- 2.83), distension (4.39 +/- 2.91) and soreness and distension (3.93 +/- 2.93) were around 5 (moderate degree), the scores of stabbing pain (1.89 +/- 2.02) were around 2 (mild degree). (3) The differences in the quantitative scores were significant for stabbing pain, distending pain, distention, soreness and distention and the others before and after treatment (all P<0.05).

CONCLUSIONDeqi of acupuncture is the mild and moderate complicated sensations manifested as distension, soreness, pain and numbness. As the invasive therapy, the filiform needle puncture will bring a certain psychological impacts on the receptors. The subjective sensation is possibly the factor for the patients' selection of acupuncture treatment.

OBJECTIVE:To study the effect of polysaccharides of Radix scrophulariae on immune function in mice under nor-mal physiological and hypoimmunical state. METHODS:80 mice were randomly divided into normal group,model group,treat-ment high-dose,medium-dose,low-dose groups and physiological high-dose,medium-dose,low-dose groups,10 in each group. Mice in normal group and model group were received distilled water (10 mL/kg) intragastrically,treatment high-dose,medi-um-dose,low-dose groups and physiological high-dose,medium-dose,low-dose groups were administrated 0.16,0.08,0.04 g/kg drug,ig,once a day,for 7 d. From the third day,mice in model group and treatment high-dose,medium-dose,low-dose groups were respectively received cyclophosphamide(100 mg/kg),ip,for 4 d to induce hypoimmunical model. Carbon clearance test was adopted to determine the carbon clearance indexes and organs(chest,spleen)indexes of mice. Another 80 mice were grouped with the same administration,serum half hemolytic value (HC50) was determined after compressed Mianyang red blood cell sensitiza-tion. Then another 80 mice were grouped with the same administration,1% dinitrofluorobenzene method was used to induce de-layed hypersensitivity in mice;its ear swelling was determined,as well as IL-2,IL-4,immunoglobulin G(IgG),immunoglobulin M(IgM),γ-interferon(IFN-γ)contents in serum,and the proliferation in vitro of splenic lymphocytes were detected. RESULTS:High-dose polysaccharides can promote the increasing of immune organ and carbon clearance indexes(P<0.05);enhance the inten-sity of delayed type hypersensitivity (HC50 increasing)(P<0.01) and improve the decreasing of serum hemolysin in model mice (P<0.01);promote the splenic lymphocytes proliferation and increase IL-2,IL-4,IgG,IgM,IFN-γ contents in serum(P<0.05 or P<0.01). CONCLUSIONS:Polysaccharides can enhance the immune function in mice under normal physiological and hypoim-munical state induced by cyclophosphamide.

Objective To detect the expression of bone morphogenetic protein receptor Ⅱ ( BMPR Ⅱ ) in human focal cortical dysplasia ( FCD Ⅱ b). Methods Fourteen specimens of FCD Ⅱ b surgically removed and pathologically verified were collected from June 2008 to June 2010 and the expression of BMPR Ⅱ in the normal brain tissues and the pathological specimens was detected by means of immunohistochemistry and western blot. Results In the normal brain tissues, BMPR Ⅱ was widely expressed in the cortical neurons of the grey matter, with no positive immunostaining in the white matter. In the cortical lesion of FCD Ⅱ b, BMPR Ⅱ was strongly expressed in the misshapen cells including balloon cells (BCs) , dysmorphic neurons (DNs) and giant neurons (GNs). Positive BMPR Ⅱ expression was also observed in the reactive astroeytes and low level expression of BMPR Ⅱ was found in the normal-appearing (NA) neurons. Western-blot analysis showed that BMPR Ⅱ expression tended to be lowered in the FCD Ⅱ b specimens compared with the normal brain tissues ( P < 0. 05 ). Conclusion The expression of BMPR Ⅱ is altered and reduced in the FCD Ⅱ b, suggesting that BMP signal pathway may participate in the pathogenesis of FCD.

Objective To investigate the effects of intravenous fluid restriction on complications after biliary surgery.Methods The clinical data of 168 patients who received biliary surgery at the Nanjing General Hospital of Nanjing Military Command from October 2006 to March 2008 were prospectively analyzed.All patients were randomly divided into test group(85 patients received fluid restriction treatment)and control group(83 patients received conventional treatment)by the sealed envelope method.The difference in the fluid volume between the 2groups was observed.Differences in systemic complication rate,local complication rate,general complication rate,time to bowl movement,length of hospital stay and mortality between the 2 groups were compared.All data were analyzed using the chi-square test,t test,Fisher exact test,Results The median total volumes of fluid in test group and control group were 1450 ml and 2420 ml,respectively,with significant difference between the 2 groups (t=-5.067,P<0.05).The median volumes of erystalloid solution in the test group was 850 ml,which was significantly lower than 1500 ml of the control group(t=-15.190,P<0.05).The postoperative systemic complication rate and general complication rate of the test group were 9%(8/85)and 19%(16/85),which were lower than 22%(18/83)and 30%(25/83)of the control group.There was a significant difference in the postoperative systemic complication rate between the test group and the control group(x2=4.837,P<0.05).The time to bowl movement and length of hospital stay were 2 days and 9 days in the restriction fluid group,which were significantly shorter than4 days and 12 days in the control group(t=-8.102,-2.003,P<0.05).The mortalities of test group and control group were 2%(2/85)and 4%(3/83),respectively,with no significant difference between the 2 groups(P>0.05).Conclusion Fluid restriction reduces the complication rate,shortens the length of hospital stay and accelerates recovery after biliary operation.

Objective To study the effect of feto-matemal microchimerism in the treatment of activated human leukocyte antigen (HLA) haploidentical mobilized peripheral blood cells against solid tumors. Methods Genomic DNA samples of 25 pairs of HLA haploidentical donors and recipients were extracted. The donor-derived HLA-DRB loci were detected with nested PCR-sequence specific primer(SSP) typing. The mixed lymphocyte proliferation action between the patients and respective donors, the engraftment of donor's cells and the serum levels of Th1/Th2 type of cytokines were measured with MTT,FISH and EIJSA method respectively. The survival time of patients with or without feto-matemal microchimerism were compared as well. Results Using nested PCR-SSP typing, the positive rates of feto-maternal microchimerism in the 25 pairs of HLA haploidentical donors and recipients were 40% in the maternal/children pairs and 0 in the paternal/children pairs. The chimerism positive patients showed less proliferation activity when cocultured with respective donors as compared with unrelated ones (P=0.03).Only one chimerism positive patient experienced the engraft of donor's cell 3 months after treatment as the donor derived XX chromosome was identified with FISH. When the data of chimerism positive patients were deleted, the serum levels of IFNγ 1 month after treatment dropped dramatically from 171.4 (26. 3～258.4) ng/L to 29. 4(1.2～39.9)ng/L. The survival time in chimerism positive patients of the maternal/children pairs was significantly longer than that in chimerism negative patients, which was (31.2±4. 3) months and (11.1±3.3) months, respectively (P=0.036). Conclusion Feto-maternal microchimerism might induce anergy in the HLA haploidentical donors, favor the engraftment of donor's progenitors and maintenance of positive microenvironment and prolong the survival time.

OBJECTIVETo observe the effect of Chinese herbal extract HuNan A-1 (HNA-1) on the thymic output function in Simian immunodeficiency virus (SIV) chronically infected rhesus macaques.

METHODSEight Chinese rhesus macaques had been infected by SIVmac239 for 16 to 21 months, and then they were randomly divided into the treatment group and the control group, 4 in each group. Monkeys in the treatment group were administered with HNA-1 by gastrogavage, once daily for 2 successive months, while those in the control group were administered with equal volume of normal saline by gastrogavage, once daily for 2 successive months. The general condition and body weight of monkeys were observed. Plasma viral loads were detected using real-time fluorescent quantitative PCR assay. CD4 percentages and counts, as well as naive CD subsets were detected using flow cytometry. T-cell receptor excision circles (TREC) were detected using real-time fluorescent quantitative PCR assay. The thymus tissue was pathologically observed using routine HE staining. The correlation between lesions of the thymus tissue, CD4 counts, naive CD counts, and TREC were analyzed.

RESULTSThere was no statistical difference in body weight, viral loads, absolute CD ratios between the two groups after treatment (P > 0.05). The altered TREC multiple showed an obvious decreasing tendency in the control group, while it showed an increasing tendency in the treatment group (P < 0.05). In both groups, destroyed structures of the thymus tissue could be seen, filled with pink unstructured material. Increased connective tissues, lowered connective cell density, and confused arrangement could also be seen in the two groups, with no obvious difference. TREC contents were positively correlated with naive CD4 counts after removing extremum (r = 0.926, P = 0.001). Naive CD4 counts were positively correlated with CD4 counts (r = 0.961, P = 0.005).

CONCLUSIONSTREC content determination, as a marker of newly thymic emigrants, could be taken as a testing method for evaluating the thymic output function. Besides, HNA-1 treatment increased the thymic output significantly in SIV chronically infected monkeys. Correlation existed among TREC contents, naive CD4 counts, and pathologies of thymus tissues, especially in late infection stage.

OBJECTIVETo investigate the antithrombotic effects and its molecular mechanisms of prazosin combined with anisodamine (Ani).

METHODSIsolated rat tail artery rings model was employed to evaluate the vasodilative effects of drugs, mice tail thrombosis model induced by carrageenan was used to study the antithrombotic effects and its molecular mechanisms of the drug composition.

RESULTSAmong alpha1-adrenoreceptor antagonists, prazosin(Pra) had the greatest relaxation rate, which was (82.6 +/- 8.9)%, and the EC50 value was 0.44 micromol/L. The drug composition of anisodamine and prazosin of different doses could decrease the length of the tail thrombosis from (24.6 +/- 4.6)mm to (6.9 +/- 2.7)mm, and the rate of thrombosis was decreased from 86.6% to 50.0%. The drug composition could prolong the prothrombin time (PT) distinctively, but it had no effect on the activated partial thromboplastin time (APTT). It also could restrain the decrease of serum levels of tissue plasminogen activator (t-PA) and 6- Keto -PGF1alpha as well as the increase of type-1 plasminogen activator inhibitor (PAI-1) and thromboxane B2 (TXB2) in the mice.

CONCLUSIONThe drug composition formed by anisodamine and prazosin has good effects of relaxing extremities tiny blood vessels and it can fight against thrombosis, its antithrombotic mechanisms may be related to the influence of the extrinsic coagulation pathway, inhibition of platelet activation functions and the promotion of fibrinolysis function.
