Objective To explore the clinical effects of laparoscopic surgery combined with marvelon,gestrinone and leuprolide in treatment of chronic endometriosis.Methods 50 cases of endometriosis were collected.They were randomly divided into observation group and control group,each group having 25 cases.The control group underwent laparoscopic surgery and the observation group underwent laparoscopic surgery combined marvelon,gestrinone and leuprolide for 3 months.The two groups were compared in clinical effects,recurrence and pregnancy rate,as well as the operation situation.Results The effective rate was 92.0％ (23/25) in the observation group and 64.0％ (16/25) in the control group.The effective rate of observation group was obviously higher than that of the control group(P ＜ 0.05).The recurrence rate was 8.0％ (2/25)in the observation group,and 32.0％ (8/25) in the control group.The recurrence rate of combination group was obviously lower than that of the simple surgical group(P ＜ 0.05).The pregnancy rate was 80.0％ in the observation group;and 48.0％ in the control group after treatment.The pregnancy rate of the observation group was obviously higher than that of the control group(P ＜ 0.05).Liver damage or other adverse reactions didn't occur to any group after the treatment.The mean time of leaving bed was (1.4 ± 0.4) d after operation in the observation group vs (3.6 ± 1.5) d after operation in the control group.Length of hospital stay was (7.6 ± 3.5) d in the observation group vs (11.5 ± 3.9) d in the control group.The difference had statistical significance(all P ＜ 0.05).Conclusions Laparoscopic surgery combined with marvelon,gestrinone and leuprolide is superior to pure surgery group in treatment of endometriosis.It can improve the effective and pregnancy rate,and reduce the recurrence rate.No obvious adverse reactions can be found,thus it is worth of clinical promotion.

ObjectiveTo study the application effect of Orem self-care theory in nursing of postoperative chemotherapy patients after cervical cancer surgery. Methods60 patients receiving chemotherapy after cervical cancer surgery were randomly divided into the self-care group and the control group with 30 cases in each group,the control group received routine nursing,on this basis the self-care group was given nursing intervention according to different requirement of patients by using three nursing model of Orem self-care theory-supportive education,part compensation,complete compensation system.The nursing effect was compared between two groups. ResultsCompared with the control group,the rate of gastrointestinal adverse reaction was lower,the anxiety and depression symptom alleviated,satisfaction degree of patients and their relatives with nursing improved,self-care ability of patients was enhanced in the self-care group,all had significant differences. ConclusionsApplication of self-care theory in nursing care of patients during chemotherapy after cervical cancer can greatly mobilize the enthusiasm of patients and their families and reduce the incidence of gastrointestinal side effects.Meanwhile,it can make close nurse-patient relationship,improve the satisfaction degree of patients and their families,improve self-care capacity,improve the quality of care,reduce the psychological symptoms of patients,so it has significant social and economic benefits.

Objective To explore the molecular mechanism of hypophrenia induced by Down syndrome (DS).Methods Ts65Dn mice were used as DS animal model.Three female mice and three male mice of three to twelve weeks old were mated.Among the 17 first-generation mice alive,five mice remained Ts65Dn trisomy and 12 mice were normal.Five Ts65Dn mice and five normal mice were selected randomly as Ts65Dn group and control group,and bred till 16 to 18 weeks old for experiments.Differential proteins in hippocampus of mice were tested by isobaric tags for relative and absolute quantitation (iTRAQ).Expressions of the differential proteins in Ts65Dn group were detected compared with those in control group.Results A total of 2805 proteins were identified in hippocampus of Ts65Dn group and control group,and significant differences were observed in the expressions of 374 proteins.Compared with those in control group,expressions of 195 proteins increased and 179 reduced in Ts65Dn group.Sorted by P value from low to high,the seven proteins with the lowest P value were uncharacterized protein C2orf47 homolog,isoform 2 of filamin A-interacting protein 1-like,zinc finger protein,isoform 1 of pericentriolar material 1 protein,SEC23 interacting protein,BAG family molecular chaperone regulator 3 and serpin H1.Conclusions Differential proteins are observed in hippocampus of Ts65Dn mice,perhaps closely correlating to neurological defects.The new technology of iTRAQ helps to screen and identify differential proteins in hippocampus.

Objective To investigate the resistant mechanism of carbapenem-resistant Escherichia coli and its relationship with endogenous infection. Methods Two carbapenem-resistant Escherichia coli strains were isolated from blood and stool of a same patient, respectively. The minimal inhibition concentrations (MIC) of the two isolates against imipenem and meropenem were determined by E-test. The susceptibility against other antimicrobial agents were done by disc diffusion method. Isoelectric focusing electrophoresis (IEF), polymerase chain reaction (PCR) amplification,cloning and sequencing, conjugation, Southern blotting were carried out to analyze the encoding gene of β-lactamases. Homology analysis of the two strains was done by pulsed field gel electrophoresis (PFGE). Results MIC against imipenem and meropenem of the two strains were both≥32 mg/L.Both strains produced KPC-2 (pI 6.7) and SHV-12 (pI 8.2) β-lactamases. blaKPC2gene was located on a 54 kb transferable plasmid. PFGE showed that the two Escherichia coli strains were derived from the same clone. Conclusions The resistance and enzyme digestion map of chromosome DNA of the two Escherichia coli strains are coincident. The Escherichia coli septicemia of this patient is probably an endogenous infection caused by the immigration of Escherichia coli from the gut.

Aim To develop King cobra antivenom from the egg yolks of immunized hens,and study dynamic expression of IgY in egg yolks.Methods chickens(white Leghorn) were immunized with detoxicated King cobra venom by formaldehyde ,Egg yolk antibody (IgY) was isotated by thiophilic interaction chromatography and identified by SDS-PAGE. Activity of IgY was evaluated by enzyme-linked immunoserbent assay(ELISA) and Double immuodiffusion. Protein was measured using folin-lowry method.

IgY was highly specific, No cross reactivity was observed among IgY and agkistrodon acutus venom and vipera venom ;Little cross reactivity was shown with cobra genus venoms.Conclusion King cobra IgY was obtained and purified from the egg yolks of immunized hens,The dynamic expression of IgY was manitered during the course of immunization,Further investigation is needed.

OBJECTIVE To report a case of AIDS associated with penicilliosis marneffei and discriminate the morphology in bone marrow examination and cultural characteristic of Histoplasma capsulatum and Leishmania donovani.METHODS The three pathogens in bone marrow morphology and cultural characteristic were studied.RESULTS AIDS patient was often infected with P.marneffei,but we could differentiated easily from other pathogens because of its breeding by splitting up and the characteristis structure in bone marrow examination.CONCLUSIONS Isolation of the P.marneffei is the golden diagnosis standard,and the examination of bone marrow is important to diagnose P.marneffei infection.

Objective To study the value of zoledronic acid combined with psychological intervention in osteoporotic vertebral compression fractures in percutaneous balloon kyphoplasty (PKP). Methods 72 patients with osteoporotic vertebral fractures underwent PKP operation from August 2013 to August 2015 were randomly divided into observation group and control group,with 36 cases,in each group. The patients in the control group were given salmon calcitonin after operation. The patients in the observation group were given zoledronic acid after operation. Both patients were given psychological care. The total effective rate of clinical treatment and the incidence of secondary osteoporotic vertebral compression fractures,Visual analogue pain scale before and after treatment (VAS), Oswestry dysfunction index questionnaire (ODI) score, bone mineral density T value changes were compared between the two groups. Results The total effective rate was 94.44% in the observation group and 77.78% in the control group (P<0.05). The recurrence fracture rate was significantly lower than that of the control group (P<0.05). After treatment, the scores of VAS and ODI in the observation group were significantly lower than those in the control group (P<0.05). The T value of bone mineral density was significantly higher than that of the control group (P<0.05). Conclusion Zoledronic acid combined with psychological intervention can effectively improve the effective rate of PKP after osteoporotic vertebral compression fractures, increase bone density and reduce the incidence of fracture, which is worthy of clinical application.

AIM: To study the effect of moderate hypothermia on immature rats with hypoxic-ischimic brain damage (HIBD). METHODS: The rats with HIBD were divided into normothermic recovered group (IN) and moderate-hypothermic recovered group (IH). Sham-operated rat pups were normothermic control group (NC) and moderate-hypothermic control group (HC). 0, 2, 6, 24, 48, 72 h after the end of hypoxic-ischemic (HI) insult, the brain was homogenized for measuring glucose and ATP, brain mitochondria was extracted for SDH activity, complex II activity and the capacity of ATP synthesization. RESULTS: In IN group, the brain glucose was significantly lower at 0 h, and recovered as normal at 2 h. The brain ATP and brain-mitochondrial SDH activities were firstly decreased at 2 h, 6 h and then recovered gradually, it was at it's peak value at 72 h. Brain-mitochondrial complex II activity and the capacity of ATP synthesis were recovered at 2 h, but they decreased again at 6 h and came to normal level at 72 h. In moderate-hypothermic group, all the indexes were significantly higher at all the time point than that in IN groups. CONCLUSION: Moderate hypothermia inhibits the decrease in the mitochondrial SDH activity, mitochondrial complex II activity and the capacity of ATP synthesis, increases the brain ATP concentration, improves the energy metabolism, and then protects the brain tissue.
