Objective To study the effects of preoperative psychological state on calm time、recovery time and the level of pain about female tumer patients with general anesthesia.Methods We selected 105 female tumer patients whose ages were from 39 years to 66 years.They were divided into two groups according to SAS grade.We observed the calm time,recovery time and the VAS about the two groups.Results The calm time and reeovery time in disquieting group was significant longer than that of the normal group.There was a significant difference between group A and group B(P＜0.01).Otherwise the grade of VAS after operation was significant greater than that of the normal group.Conclusion The disquieting preoperative psychological state would effect the results of general anesthesia.The anesthetist should pay attention to the visiting patients before operation.

Objective To study the signal pathway of apoptosis of renal proximal tubular cells (RPTC) caused by cisplatin for prevention of toxic effects of cisplatin on kidney. Methods pcDNA3.1/Hygromycin vector and pEGFP-C3 vector including Bcl-2(Bcl-acta,Bcl-cb5 and Bcl-nt) were co-transfected in RPTC.After treated with cisplatin, Bax was activated,cytochrom C release and apoptosis were analyzed with confocal microscope and immunofluoresence technique. Apoptotic cells stained with Hoechst33258 were also counted and statistically analyzed. Results The percent of cytochrom C release (35.74%) in Bcl-cb5 transfected group was higher than those in Bcl-nt group (18.7%) and Bcl-acta group(24.6%)(P

Objective To evaluate effects of two different flap designs (envelope flap and triangular flap) on complica?tions after the mandibular third molar surgery. Methods A randomized, self controlled clinical trial design was selected for 52 patients treated in the outpatient surgery of Stomatological Hospital Affiliated to Tianjin Medical University. Patients were treated with envelope flap design for lower third molar removal in one side and triangular flap on the other side. VAS scores were used to evaluate postoperative pain. The postoperative swelling was evaluated by patient`subjective index. The degree of the upper and lower incisor distance was used to evaluate trismus. Data of postoperative swelling, pain and trismus were re?corded 1, 2 and 7 days after surgery. Data of postoperative wound dehiscence, bleeding situation and alveolitis were also re?corded and compared between two groups. Results There were no significant differences in postoperative pain after 1, 2 and 7 days between two flap designs (P>0.05). After 1 and 2 days there was more severe facial swelling in triangular flap group than that of envelope flap group (Z=2.005, Z=2.017, P<0.05). There was more limited mouth opening after 1 and 2 days in triangular flap group than that of envelope flap group (t=2.578, t=2.410, P<0.05), but on the seventh day there was no significant difference in the severity of facial swelling and trismus between two groups (P>0.05). There were no signifi?cant differences in postoperative pain, alveolitis, bleeding and wound dehiscence between two groups (P > 0.05). Conclu?sion The envelope flap is more conductive to the early recovery in patients after surgery, but in the long term there is no ob?vious difference between the two flap designs.

Objective To explore the expression of the mRNA level of Fas (CD95) ligand/FasL and Fas-associated phosphatase-1/FAP-1 in acute myeloid leukemia. Methods The expression of FasL and FAP-1 were detected in 54 patients with AML and 10 normal subjects by semi-quantitative reverse transcriptase-polymerase chain reaction (RT-PCR). β-actin used as internal reference. The changes of FasL was observed after induction chemotherapy in 16 AML patients. The expression of Fas was detected in 54 patients with AML by flow cytometry. Results The mRNA levels of FasL and in 54 patients were remarkably higher(P <0.05) than the normal controls. The rates of first complete remission(CR) were significantly higher in FasL(+) (77.78 %) than in FasL(-) cases(16.67 %) (P<0.01). The FasL level declined in 10 patients with good response to therapy (P<0.01), and high level in 6 nonresponding patients with poor response (P>0.05). The mRNA levels of FAP-1 in 54 patients was remarkly higher than that of the normal control. 8/29 cases in Fas-positive group were positive for FAP-1 mRNA expression. 19/25 cases in the Fas-refractory group didn't express FAP-1 mRNA. Conclusion The expression of FasL was high in AML. The rates of complete remission were high in FasL positive cases. The FasL level declined in patients with good response to therapy. The expression of FAP-1was partly expressed in AML. The expression of FAP-1 was less in Fas positive group.

Abstract: Objective　To investigate the status of participation in highly active antiretroviral therapy (HAART) among individuals infected with human immunodeficiency virus (HIV)/patients with acquired immunodeficiency syndrome (AIDS) (hereinafter referred to as HIV/AIDS) in Hainan province, and to analyze the immunological outcomes and their influencing factors following treatment. Methods　In this study, HIV/AIDS patients treated in Hainan Province until 2022 from the antiretroviral treatment were selected from the antiviral treatment submodule of the China Disease Prevention and Control Information System. According to the inclusion and exclusion criteria, a total of 3 150 HIV/AIDS patients were enrolled. Logistic regression analysis was used to analyze factors affecting the immunological effect of antiretroviral therapy. Results　Of the 3 150 subjects, 2 906 achieved immunological success, accounting for 92.2%. The M（P25，P75） CD4+T lymphocyte count after treatment was 491 (351, 656) cells/μL. There were significant differences in the increase in CD4+ T lymphocyte counts after treatment compared to baseline across different CD4+T levels (P<0.001). Multifactorial logistic regression analysis showed that being divorced or widowed (OR=0.50, 95%CI: 0.31-0.79), age ≥60 years at the onset of treatment (OR=0.51, 95%CI: 0.29-0.90), the interval from diagnosis to treatment of 1 to <12 months (OR=0.55, 95%CI: 0.40-0.77), 12 to <60 months (OR=0.53, 95%CI: 0.34-0.80), and ≥60 months (OR=0.41, 95%CI: 0.23-0.75), as well as a CD4+ T cell count of 300 to <400 cells/μL (OR=0.36, 95%CI:0.22-0.58) and 400 to <500 cells/μL (OR=0.30, 95%CI:0.18-0.49) were negative correlation with immunological success (P<0.05). On the other hand, homosexual transmission (OR=3.46, 95%CI:2.03-5.90), heterosexual transmission (OR=1.91, 95%CI: 1.14-3.19), other/unknown transmission (OR=3.13, 95%CI: 1.50-6.53), treatment years count 2 to <4 years (OR=1.71, 95%CI: 1.13-2.58), 4 to <6 years (OR=2.86, 95%CI: 1.81-4.51), and ≥6 years (OR=2.21, 95%CI: 1.47-3.32) were positive correlation with immunological success (P<0.05). Conclusions　The highly active antiretroviral therapy has achieved good immunological effects among patients with HIV/AIDS in Hainan Province. It is essential to expand HIV monitoring and detection, to diagnose and treat at an early stage, and to continue strengthening medication compliance education to further improve the immunological effects of treatment.

Objective To explore the mechnism of toxicity induced by cisplatin on renal proximal tubular cells(RPTC) line and anti-apoptosis mechanism of BCL-2 with transfection of different mutant BCL-2 in vitro.MethodsRPTC was translocated with different mutants BCL-2(s).Cell apoptosis induced by cisplatin on RPTC was analyzed with confocal and flurencent microscope.The cell apoptosis was measured with Hoechst33258 after treatment with cisplatin.Results Different mutant BCL-2(BCL-acta,BCL-cb5)were translocated on mitochondrial and Endoplasmic Reticulum(ER) respectively.BCL-acta protected RPTC from apoptosis induced by cisplatin more easily than BCL-cb5 group in a time-dependant manner(P

Objective To investigate the potential mechanisms of vascular dementia (VD) by comparing the neuroethological and pathological changes of two VD models, established with spontaneously hypertensive rat (SHR) and the rat, of which the bilateral carotid arteries were ligated. Methods Ten male SHRs were employed and defined as hypertension control group. Thirty male Wistar rats were randomly assigned to operation group (bilateral carotid arteries were ligated), sham group and control group. All rats enrolled in the operation group were undergone a permanent ligation of bilateral carotid artery (2-VO). The memory function of rats was estimated by the mean escape latency of Morris water maze. The morphological changes of neuron cells in the frontal lobe, temporal lobes, hippocampus and thalami were observed with HE staining, while the changes of white matter around cerebral ventricles were checked with LFB staining, and the demyelination of nerve was calculated. Results The memory function of rats in SHR control group and Wistar operation group was decreased compared with that of the rats in sham group and control group (P0.05). Conclusions SHRs without intervention and Wistar rats undergone 2-VO can be used to reproduce the ideal VD model. Both chronic permanent hypoperfusion and hypertension may lead to the loss of neurons and myelin which may result in memory dysfunction. Hypoperfusion is even more harmful than hypertension. The present study suggests that loss of neurons and myelin may play a role in the VD.

Objective To discuss the effect of small needle knife therapy on collagensⅠ and Ⅲ in the hypertrophic scar tissues that was subcutaneously transplanted into nude mice. Methods Six samples of human hypertrophic scar tissues without cuticle were subcutaneously transplanted into the back of 24 nude mice to create the animal models of hypertrophic scar. Ten days after of the operation,the mice were divided into control,0.1 mg/ml triamcinolone,0.2 mg/ml triamcinolone,and small needle-knife groups with 6 mice in each. Specimens of the scar tissues were collected in 14 days for immunohistochemistry to detect the collagen Ⅰ and Ⅲ. Results In all the groups,collagens Ⅰand Ⅲ distributed extensively in the cytoplasm of fibroblast and tissues. Image analysis showed that the concentration of collagens Ⅰand Ⅲ in 0.1 mg/ml and 0.2 mg/ml triamcinolone groups were significantly lower than those in the control (0.09?0.03,0.11?0.05 and 0.12?0.02,0.11?0.01 vs. 0.17?0.04,0.19?0.03,P0.05). Conclusions Small needle-knife therapy can reduce the concentration of collagens Ⅰand Ⅲ in transplanted hypertrophic scar tissues in nude mice.
