To observe and compare the therapeutic effects of treating female menopausal syndrome with auricular-point-pressing therapy and acupuncture, 86 patients were randomly divided into auricularpoint pressing group and acupuncture group, the comparative observation was conducted according to a modified Kupperman index. Statistical analysis showed that there's no significant difference between the therapeutic effects of the two groups. Auricular-point-pressing therapy and acupuncture were both effective in treating female menopausal syndrome, while auricular-point-pressing had the advantages of easy operation and acceptance.

Objective To evaluate the perioperative management and therapeutic efficacy of procedure for prolapse and hemorrhoids (PPH) in elderly patients with serious hemorrhoids. Methods The clinical data of 52 elderly patients (aged 60 years or over) with serious hemorrhoids treated by PPH from March 2005 to November 2007 were analyzed restrospectively. Results All the operations were successfully completed. The average operation time was (15.3±3.2) min, the average blood loss was (15±1.7) ml and the average hospitalization time was (4.5±2.6) days.Patients were followed for 1-20 months with (14.2±2.4) months for average. The follow-up rate was 92.3%(48/52). Complications included urinary retention in 18 cases(37.5%), anastomotic bleedings in 2 cases (4.2%), postoperative pain of anus in 4 cases (8.4%), recurrence in 1 case (2.1%),hypoglycemia in 1 case(2.1%), and 1 case (2.1%)was found stricture in rectum at 2 months after the procedure and no case developed rectovaginal fistula. Conclusions Old age is not the contraindication for PPH treatment of the serious hemorrhoids. Proper perioperative management may decrease the postoperative complications and improve the life quality of the patients.

AIM: To observe the effects and safety of clopidogrel used in percutanous coronary intervention (PCI) while acute occlusions of coronary arteries happened. METHODS: 92 patients with acute occlusions of coronary arteries were treated through PCI and they were randomized equally into following groups: clopidogrel group (CPG group) and ticlopidine group (TCP group). Each patient was treated with clopidogrel 25 mg bid or ticlopidine 250 mg bid for 4 weeks after PCI. RESULTS: Compared with the control group, there was not significantly difference in platelet aggregation ( 45.36 ? 2.98 vs 51.60 ? 2.56 ) and clinical effects ( 97.95 % vs 93.02 %) after 3 weeks. The proportion of patients with adverse events who had to release the treatment was 2.04 % (CPG group) and 16.27 % (TCP group). CONCLUSION: The clinical effect of clopidogrel is similar to ticlopidine and shows less adverse events.

OBJECTIVETo investigate the association between catecholamine-beta-adrenoceptor (beta-AR)-adenosine 3', 5'-monophosphate (cAMP) system and long-term prognosis in patients with chronic heart failure (CHF).

METHODSThe study population comprised 73 patients with CHF (EF: 23% +/- 10%) with a mean follow-up of 3.8 +/- 1.9 years. Plasma levels of norepinephrine (NE) were measured using high performance lipid chromatography, beta-adrenergic receptor density (Bmax) and the content of cAMP in peripheral lymphocytes were calculated using 3H-dihydroalpneolo as ligand and competitive immunoassay, respectively. Deaths due to cardiovascular events within the follow-up period were registered.

RESULTSThe total mortality was 64.7%, 57.4% of which was for cardiogenic (worsening heart failure: 32.4%; sudden death: 25.0%). In the cardiogenic death group, plasma levels of NE and epinephrine (E) (3.74 nmol/L +/- 0.09 nmol/L and 3.17 nmol/L +/- 1.0 nmol/L) and the contents of peripheral lymphocyte cAMP (3.64 pmol/mg protein +/- 1.4 pmol/mg protein) were significantly increased as compared with the survival group (2.68 nmol/L +/- 0.07 nmol/L, 2.41 nmol/L +/- 0.24 nmol/L and 2.73 pmol/mg protein +/- 0.9 pmol/mg protein, respectively, all P < 0.01). In the sudden death group, plasma levels of NE and E (5.01 nmol/L +/- 0.06 nmol/L and 4.13 nmol/L +/- 0.08 nmol/L) were significantly increased as compared with the worsening heart failure group (2.49 nmol/L +/- 0.07 nmol/L and 2.33 nmol/L +/- 0.8 nmol/L, all P < 0.001) and to the survival group (2.68 nmol/L +/- 0.07 nmol/L and 2.41 nmol/L +/- 0.14 nmol/L, all P < 0.01). The incidences of sudden death were 0%, 75%, and 100% (chi(2) = 16.018, P < 0.01) in patients with plasma NE < 2.5 nmol/L, NE 2.5 nmol/L - 4.5 nmol/L, and NE > 4.5 nmol/L, respectively. In the worsening heart failure group, the content of peripheral lymphocyte cAMP (4.46 pmol/mg protein +/- 0.18 pmol/mg protein) was significantly increased compared with the sudden death group (2.39 pmol/mg protein +/- 0.9 pmol/mg protein, P < 0.001) and to the survival group (2.73 pmol/mg protein +/- 1.1 pmol/mg protein, P < 0.001). The worsening heart failure death occurences were 5.0%, 72.2%, and 100% (chi(2) = 14.26, P < 0.01) in patients with a content of peripheral lymphocyte cAMP < 2.5 nmol/L, cAMP 2.5 nmol/L - 4.5 nmol/L, and cAMP > 4.5 nmol/L, respectively. Bmax in peripheral lymphocyte was not significantly different (P > 0.05) among the sudden death, worsening heart failure, and survival groups in CHF patients.

CONCLUSIONSPlasma levels of catecholamine increase significantly, and Bmax and the contents of cAMP in peripheral lymphocytes decrease significantly in patients with CHF. High plasma catecholamine levels may be associated with sudden death, and high intralymphocyte cAMP content may be associated with worsening heart failure in CHF patients.

OBJECTIVE: The present study is to evaluate the biological functions of long non-coding RNA (lncRNA), X-inactive specific transcript, X-inactive specific transcript (XIST) in human epithelial ovarian cancer (EOC). METHODS: XIST was upregulated in EOC cell lines, CAOV3 and OVCAR3 cells by lentiviral transduction. The effects of XIST overexpression on cancer cell proliferation, invasion, chemosensitivity and in vivo tumor growth were investigated, respectively. Possible sponging interaction between XIST and human microRNA hsa-miR-214-3p was further evaluated. Furthermore, hsa-miR-214-3p was overexpressed in XIST-upregulated CAOV3 and OVCAR3 cells to evaluate its effect on XIST-mediated EOC regulation. RESULTS: Lentivirus-mediated XIST upregulation had significant anticancer effects in CAOV3 and OVCAR3 cells by suppressing cancer cell proliferation, invasion, increasing cisplatin chemosensitivity and inhibiting in vivo tumor growth. Hsa-miR-214-3p was confirmed to directly bind XIST, and inversely downregulated in XIST-upregulated EOC cells. In EOC cells with XIST upregulation, secondary lentiviral transduction successfully upregulated hsa-miR-214-3p expression. Subsequently, hsa-miR-214-3p upregulation functionally reversed the anticancer effects of XIST-upregulation in EOC. CONCLUSION: Upregulation of lncRNA XIST may suppress EOC development, possibly through sponging effect to induce hsa-miR-214-3p downregulation.

The aim of this study was to evaluate the efficiency and safety of ultrasound-guided thrombin injection on femoral pseudoaneurysm (FPA) as compared to ultrasound-guided local oppression. Eleven cases of FPA were enrolled and 7 cases received ultrasound-guide thrombin injection (injection group), and the remaining 4 cases were treated with local oppression (oppression group). Efficiency and safety were analyzed by ultrasound and subsequent follow-up. The results showed that 1 case relapsed in oppression group while no relapse occurred in thrombin injection group. Ultrasound-guided thrombin injection is better for treatment of FPA in terms of effectiveness and safety.

OBJECTIVETo investigate the bacterial epidemiology in our department in recent years, so as to provide assistance to the clinical management of burn patients.

METHODSA retrospective analysis was carried out with 345 bacterial cultures from burn wound and drug-sensitivity results in 784 burn patients during 1993 to 1999 in our department.

RESULTS(1) Among all the bacteria, gram negative (G(-)) bacilli accounted for 56.8%, while gram positive (G(+)) cocci and fungi in 3.8%. (2) Among all the G(+) cocci, 65.4% were Staphylococcus aureus, in which MRSA was identified in 53.9% during 1993 - 1999 and in 64.3% during 1998 - 1999. Pseudomonus aeruginosa accounted for 37.2% of all G(-) bacilli. (3) The 3rd generation of cephalosporins shew excellent anti-bacterial capabilities, but the bacterial resistance to them increased significantly. (4) MRSA was very sensitive to both vancomycin and norvancomycin with no report of antibiotic resistance to them.

CONCLUSIONG(-) bacilli were still predominant bacteria in our burn department when compared to G(+) cocci. The 3rd generation cephalosporins are the routine antibiotics for the present. But resistant bacteria are on the increase. There are also more and more MRSAs isolated from burn wounds. For this, vancomycin and norvancomycin should be preferably used.

Objective:To explore the relationship between respiratory mechanics and right heart function during ARDS mechanical ventilation through the establishment of Beagle dogs acute respiratory distress syndrome (ARDS) animal model and the application of different levels of mechanical ventilation, which will provide theoretical basis for right heart protective ventilation strategy of ARDS.Methods:Beagle dogs were anesthetized successfully and then pulmonary artery floating catheter, esophageal manometric catheter and femoral artery catheter were inserted. Under the pressure control mode, the driving pressure was fixed. After adjustment, PEEP gradually increased from 2 cmH 2O to 14 cmH 2O. The changes of respiratory mechanics, hemodynamics and right heart function were observed. ARDS model was established by injecting oleic acid into central vein, and mechanical ventilation with the same parameters was given after the model was established successfully. In contrast to itself, the changes of respiratory mechanics, hemodynamics and right heart function indexes of experimental dogs before and after modeling were analyzed. In the group, the indexes of different PEEP were compared by ANOVA, and then compared by Student-Newman-Keuls. The difference was statistically significant at a P value <0.05. Results:Before modeling, the peak airway pressure (P peak) and plateau pressure (P plat) increased with the increase of PEEP ( F=232.733,196.33, P<0.05). However, P trans-I, P trans-E, C stat and Vt decreased significantly ( F=4.524, 6.499, 64.803, 2.31, P<0.05). The area of change of right ventricle (FAC) became smaller ( F=3.09, P<0.05); SV first increased and then decreased ( F=3.24, P<0.05), and CVP and MPAP increased ( F=19.07,14.81, P<0.05). There was no significant difference in TAPSE, MAP, HR and SpO 2 ( P>0.05). After modeling, as PEEP increased, P peak, P plat, P ES-I and P ES-E increased significantly ( F=24.829, 41.95, 9.78, 87.86, P<0.05). Vt, P trans-I, P trans-E, C stat and Vt first increased and then decreased ( F=2.91, 4.29, 5.84, 48.890, P<0.05). TAPSE and SV first increased and then decreased ( F=6.22,6.54, P<0.05). CVP and MPAP increased ( F=5.23, 19.24, P<0.05). MAP increased first and then decreased ( F=5.02, P<0.05). SpO 2 increased ( F=2.77, P<0.05). FAC and HR had no statistical significance ( P>0.05). Conclusions:Trans pulmonary pressure and lung compliance can reflect the effectiveness of ARDS lung recruitment, and have good synergy; with the increase of PEEP, the right ventricular systolic function TAPSE is first affected, and SV compensatory increase, but with the increase of PEEP, TAPSE and SV decrease; pulmonary blood flow distribution is more important in improving alveolar oxygenation. Therefore, real-time monitoring of trans pulmonary pressure, TAPSE and intrapulmonary blood flow should be performed in ARDS treatment.
