Objective To study the effects of three therapies on shoulder pains after gynecological laparoscopies.Methods After the gynecological laparoscopies,180 patients were randomly assigned to hot compress group(n=57),oxygen therapy group (n=65)and routine care group as control group(n=58).All the patients in the three groups were given oxygen inhalation for three hours.Besides,those controls were given mental care,comfort support and massage,while those in the two experiment groups were managed with hot compress on the shoulder and oxygen inhalation via nasal tube at 2 L/min each for 2 hours at 8 am and 4 pm on the first day.The three groups were compared in terms of shoulder pains,at different time points on the first day(at 8 am,4 pm and 8 pm). Results After intervention,there were significant differences between the three groups in terms of shoulder pains(P<0?05).In both experiment groups,the scores on the shoulder pains after intervention were significantly lower than those before intervention(P<0?001). Conclusions Hot compress and oxygen treatment are both effective in relief of the shoulder pain after gynecological laparoscopy. Therefore,the therapy can be decided on economic conditions and postoperative rehabilitations.

Progestagen-associated endometrial protein (PAEP) gene mainly expresses in the secretory phase endometrium and decidua in early trimester of pregnancy.In recent years,it is reported that PAEP is abnormally expressed in many kinds of tumors,such as breast cancer,endometrial carcinoma,ovary cancer,stomach cancer and melanoma.PAEP gene plays an important role in tumorigenesis and tumor development.The application of PAEP gene as an indicator for clinical diagnosis,prognostic and therapy needs further studies on the influence of PAEP gene on tumor biological behaviour.

Objective To determine the urine lead level in school_age children under conditions of environmental lead exposure and evaluate the effects of the presence of body lead on IQ, academic achievement and behavior in school of these children. Methods The concentrations of urine lead and IQs for 118 children aged 7～12 were measured. The academic achievement, behavior in school and the correlated factors were derived from the questionnaires given to their teachers and parents. Results The urine lead level of 118 children was (7.04?3.53)?g/L. In children who lived in city central area the urine lead level was (7.71?3.52)?g/L. It was significantly higher than that of children who lived in a suburban area [(6.37?3.45)?g/L]; No significant differences were observed in IQ between children in city and suburbs. The results by single factor analysis showed that the urine lead level [(10.31?2.16)?g/L] in the lower IQ group (IQ

Objective To discuss the efficacy of omeprazole and pantoprazole in treatment of peptic ulcer hemorrhage.Methods 80 patients with peptic ulcer hemorrhage were selected,they were divided into two groups randomly.The observation group (41 cases) was given pantoprazole by intravenous drip.The control group (39 cases) was given omeprazole by intravenous drip.The efficacy and safety of omeprazole and pantoprazole in treatment of peptic ulcer hemorrhage was evaluated by efficacy,pH before and after treatment,bleeding time,hospitalization and bleeding volume,and adverse reaction during treatment.Results The effective rate was 92.7％ in the observation group and 89.7％ in the control group.There was no statistical significance on effective rate between two groups.But the excellent rate of observation group was higher than that of the control group (P ＜ 0.05).Before treatment,the gastric acid was acidic.There were no statistical significance on pH value between two groups.After treatment,the pH value was increased in two groups.The pH value of observation group was higher than that of the control group (P ＜ 0.05).The hospitalization,hemostasis time and bleeding volume was shorter than that of the control group (P ＜ 0.05).During treatment,the patients given pantoprazole had less adverse reaction (P ＜ 0.05).Conclusion Pantoprazole and omeprazole are suitable for treating peptic ulcer hemorrhage.But the antacid and hemostatic effect of pantoprazole was better with high safety.It was worthy of clinical application.

Objective To investigate the effects and possible mechanisms of decitabine on heat-shock protein 22 (HSP22) expression in hematopoietic tumor cell lines and bone marrow samples from patients with hematopoietic tumor.Methods The expression of HSP22 in 13 hematopoietic tumor cell lines,20 primary patients' samples and 10 normal donor' samples were detected by semi-quantitative reverse transcription polymerase chain reaction (RT-PCR).After HSP22 induction with a demethylating agent decitabine (2 μmol/L),the methylation of the HSP22 promoters in hematopoietic tumor cell lines,healthy donors and bone marrow samples from patients with hematopoietic tumor were detected by methylation specific PCR (MSP).Results Expression of HSP22 was not detected in 13 hematopoietic tumor cell lines,20 primary patients' samples or 10 healthy donors' samples.Decitabine can induce the expression of HSP22 in hematopoietic tumor cell lines and bone marrow samples from patients with hematopoietic tumor.Decitabine can maintain partially demethylation of HSP22 promoters in hematopoietic tumor cell lines.HSP22 promoters were highly methylated in BMMC of the healthy donors and patients with hcmatopoictic tumor.Conclusion Decitabine can induce the expression of HSP22 in hematopoietic tumor cells partly by demethylation of HSP22 promoters.

Objective To investigate the effect of equol on ERK mediated signal transduction pathway and to clarify its mechanism of proliferation inhibition on human ovarian carcinoma cell line SKOV-3. Method SKOV-3 cells were treated with 10-8,10-7,10-6,10-5,5?10-5,10-4 mol/L equol for 24,48 and 72h. After pretreatment with 10 ?mol/L U0126 an ERK signaling pathway inhibitor or ICI182,780,estrogen receptor inhibitors for 1h,then treatment with 50 ?mol/L equol for 2h,the cell viability was examined and the expressions of ERK and p-ERK protein were determined using Western blotting. Results Equol was demonstrated to inhibit SKOV-3,proliferation time-and dose-dependently. The expression of p-ERK protein was decreased in dose-dependent manner,while the expression of total ERK was unchanged. Both the single use of U0126,or ICI182,780,and combined with equol could decrease the expression of p-ERK protein. Conclusion Equol could inhibit proliferation in ovarian carcinoma cell lines SKOV-3. Its inhibitory effect appears to be due to down-regulation of p-ERK protein.

Objective To detect the content of(1-3)-β-D-dextran(BG)and CD4T lymphocytes in order to early diagnose invasive pulmonary fungal infection(IPFI)in AIDS patients.Methods According to the qualified lower respiratory tract fungal culture re-sults,153 patients with pulmonary infection symptoms and definitely diagnosed AIDS were divided into the positive IPFI group(63 cases)and the negative IPFI group(90 cases);then plasma BG and CD4T lymphocytes were simultaneously detected in the positive IPFI group,negative IPFI group and 50 healthy controls.The same index was performed the pairwise comparison in each group and the statistical analysis was conducted.Results The mean values of BG and CD4T lymphocytes in the positive IPFI group were (56.30±15.38)pg/mL and(56±41)/μL;which in the negative IPFI group were(21.32±14.26)pg/mL and(200±53)/μL;which in the healthy control group were(2.89±1.55)pg/mL and(480±89)/μL.The pairwise comparison of BG and CD4T lymphocytes showed the statistical differences among the three groups by the t-test(P <0.01).Conclusion The combined detection of BG and CD4 lymphocyte has the value in early diagnosis of IPFI)on AIDS apparent infection.

Objective To investigate the epidemiological features of respiratory syncytial virus (RSV) A and B in hospitalized children with acute respiratory tract infections(ARTIs) and to analyze the genetic characteristics of G protein gene of RSV in Chongqing area, especially for BA strains. Methods Nasopharyngeal secretions collected from 508 hospitalized children with ARTls from April, 2008 to March, 2009 were screened for RSV using RT-PCR. Full length G protein gene was amplified by RT-PCR from 10 RSV subtype A and 29 RSV subtype B strains. Results Out of the total 508 specimens, 126 (24.8%) were revealed positive for RSV. RSV subtype A and B viruses accounted for 34.1% and 63.5% of the total positive specimens, respectively. The remaining 2.4% of the specimens were positive for both subtype A and B. At the nucleotide level, identities between the 10 subtype A virus G genes and that of the prototype strain A2 were 91.4% -92.0%, indicating genotype GA2. Identities of the 29 subtype B virus G genes and that of the CH18537 strain were 92.0%-93.0%. Nineteen out of 29 RSV subtype B isolates contained highly repeated 60 nucleotides insertion in G protein gene, namely BA strain. As compared to the prototypes, the RSV G protein gene included nucleotide deletion, insertion, substitutions, especially in the carboxy-terminal third of the G gene. Condnsion RSV has been the major cause of acute respiratory tract infections in children in Chongqing area. Subtype B strains, especially BA strains, were predominant during the study peried. Whether the predominated circulation of BA strain is resulted from enhanced attachment function of G protein remains unknown.

Objective To study the effect of the levels of serum gonadal hormone and plasma calcitonin gene-related peptide(CGRP) on the hot flushes symptom of perimenopausal women. Methods 65 perimenopausal women (35 with hot flushes and 30 without hot flushes) and 25 healthy fertile women were enrolled. The subjects were analyzed for serum estradiol (E2), follicle-stimulating hormone (FSH) ,luteinizing hormone (LH) and plasma calcitonin gene-related peptide (CGRP). Results. ① There were no significant differences of the E2 levels between the perimenopausal women with and without hot flushes (P>0.05). The levels of FSH and LH were significantly higher in the women with hot flushes than women without hot flushes and fertile women(P<0.05),② The levels of plasma CGRP were significantly higher in the women with hot flushes than women without hot flushes (P<0.05), and significantly lower than fertile women,③The levels of plasma CGRP were significantly higher in severe hot flu-shes group than that in the mild hot flushes group and moderate hot flushes group(P<0.05), the severity of hot flu-shes was positively related to the level of plasma CGRP(rs=0.823, P<0.01), but there was no relationship be-tween serum E2 and the severity of hot flushes (P>0.05). Conclusion The occurrence of perimenopansal hot flu-shes might be closely related to the decline and fluctuation of serum E2,increase of FSH and LH and the concentra-tion variety of plasma CGRP.
