Objective To explore the influence on the quality of marital and life of the congenital absence of vagina patients with operation by psychological intervention.Methods The congenital absente of vagina patients were divided into psycholOgical intervened group(n=18,all cases were treated with the cognitive and behaviour therapy)and without intervened group(n=11).Before and after treatment the scores of the nottingham health poofity(NHP)were used in the two groups.After treatment the Olson's enrich questionary were tested also.Results The scores of NHP and Olson of psychological intervened group were significantly superior to those without intervened group(P＜0.05 or P＜0 01).Conclusion The cogntive and behaviour theraopy before operation is good for the quality of marital and life in congenital absence of vagina patients.

Objective To explore the influence of psychological intervention on quality of life(QOL) in the hysteromyoma patients underwent surgery. Methods Three hundred and twenty patients with hysteromyoma were divided into the psychological intervened group ( all cases were treated with the comprehensive psychological intervention) and the control group (without intervention). Before and after treatment, the scores of the Olson's Enrich Questionary and the Nottingham Health Poofity (NHP) were assessed in the two groups. Results Before surgery, the scores of N HP and Olson were not significantly different between the psychological intervened group and the control group ( P > 0. 05 ). The scores of NHP of total hysterectomy in the control group after surgery were higher than that before surgery,and the scores of Olson were lower significantly ( P <0. 05 or P <0. 01). The scores of NHP of subtotal hysterectomy, myomectomy and blood vessel involvement treatment in the control group after surgery were significantly lower than that before surgery, and the scores of Olson were higher ( P < 0. 05 or P < 0. 01 ). After surgery,the scores of NHP of all patients in the psychological intervened group were significantly lower than that in the control group,and the scores of Olson were higher significantly (P <0. 05 or P <0. 01). There was no significant difference in ovarian hormones level between pre- and post- surgery (P > 0. 05). Conclusions The comprehensive psychological intervention pre- and post- surgery is good for the quality of life in hysteromyoma patients.

Objective To observe the ultrastructural changes in the midgut epithelium of Ixodes sinensis after infesting rabbits immunized with {Mr 105 000} purified tick antigen. MethodsNew Zealand rabbits were inoculated with {Mr 105 000} purified antigen by means of mutiple intradermal injection in foot pad, groin and back. Each immunized rabbit was infested by 30 female Ixodes sinensis. At 24 hours, 48 hours, 72 hours, 5 days and 8 days after infestation, three Ixodes sinensis in each group were observed for ultrastructural changes in the epithelium of their midgut. Results Histological examinations showed that with the time going, digestive cells of the ticks after infesting hosts became more and larger with dense and regularly arranged microvilli, enriched organella, distinct unit_membrane structure, and the appearance of tubli, small vacuole, numerous lipid droplets and hematin granules. These cells also developed a highly infolded basal lamina, forming a labyrinth system. The digestive cells of immunized group were however greatly damaged, whose number and volume were significantly different from control groups. From 24 to 48 hours after infestation, the midgut epithelium of Ixodes sinensis showed pathological changes with the basal lamina becoming thinner, looser and broken; digestive cells damaged and vacuolated; microvilli decreased, shortened and irregularly arranged; the mitochondria swollen and its crests reduced, shortened and even with myeloid changes; the rough endoplasmic reticulum dilated; lipid droplets and hematin granules decreased; phagocytic and pinocytic activity weakened; and basal labyrinth system vacuolated. From 72 hours to 8 days after infestation, cells were severely damaged, organella were denatured and necrotic, nuclei showed pyknosis and cells lysed. Conclusion The rabbits immunized with {Mr 105 000} purified ixodic protein have acquired the adoptive immunity against Ixodes sinensis; in the anti_tick immunity described above, the midgut of Ixodes sinensis is the major affected site.

Objective To investigate the significance of hypoxia inducible factor-1(HIF-1) expression in ovarian endometriosis (Oems). Methods Elivision Tm plus Immunohistochemical and Stereology methods were used to detect HIF-1 expression in 30 cases of ectopic endometrium, 30 cases of eutopic endometrium in ovarian endometriosis and 30 cases of endometrium in ovarian teratoma as the normal control. Quantitative images analysis was performed with the aid of computer to collect and analyze the mean optical density (MOD) of HIF-1 expression. Results The MOD values of HIF-1 in ectopic and eutopic endometrium of Oems and the normal control were 0. 077 ± 0. 014, 0. 070 ± 0. 013 and 0. 061 ± 0. 007 respectively, which showed significantly differences between each other groups(F = 37. 738, P ＜ 0. 01 ＝. HIF-1 expression in proliferative phase (0.076 ±0.007) of eutopic endometrium of Oems was significantly higher than that in secretary phase (0. 059 ±0. 014) (t = 6. 918 ,P ＜0. 01 ＝; which was also significantly higher than that of the normal control in the same phase (0.060±0.007) (t=-12.724,P ＜0.01 ＝.Conclusion HIF-1 may play an important role in the pathogenesis and development of Oems.

Objective To assess the surgical effectiveness of pelvic endometriosis (EMS) by Laparoscopic. Methods Retrospective analysis was performed in 1272 pelvic EMS patients underwent laparoscopic surgical treatment. All patients were classified into four groups according to the R-AFS,63 patients of Ⅰ stage,44 patients of Ⅱ stage,475 patients of Ⅲ stage and 690 patients of Ⅳ stage. Symptoms of EMS,surgical effect and follow-up outcomes were compared. Results In all stages, there were no significant differences on moderate to severe dysmenorrhea,increase in CA125 and infertility (Ps ＞ 0. 05 ). In the EMS patients combined with AM or/and DIE, the rates of the moderate to severe dysmenorrhea, CA125 increase and infertility were 84.6% (11/13 ) ,92.3 %(12/13) and 53.8% (7/13)in stage Ⅰ ,81.8% (9/11) ,90. 9% ( 10/11 )and 54.5% (6/11) in stage Ⅱ ,84.8%(173/204) ,93. 1% (190/204) and 47.1% (96/204) in stage Ⅲ ,and 81.6% (213/261) ,91.2% (238/261) and 46.4% ( 121/261 ) in stage Ⅳ, respectively. The rates in non-consolidated AM or/and DIE patients were 46.0%(23/50),62.0% (31/50) and 22.0% ( 1 1/50) in stage Ⅰ ,45.5 % ( 15/33 ),54.5% ( 18/33 ) and 18.2% (6/33)in stage Ⅱ ,41.7% ( 113/271 ) ,62.7% ( 165/271 ) and 23.6% (64/271) in stage Ⅲ ,and 47.3% (203/429),60.1% (248/429) and 21.7% (93/429). The difference between the two groups with and without consolidated AM or/and DIE had statistical significance( P ＜ 0.05 or P ＜ 0.01 ). After the treatment, the scores of life's energy, ache,emotion,sleep,social activity and body movement of NHP were significantly superior than those before treatment in all patients ( P ＜ 0.01 ). The surgery time-consuming of Ⅲ and Ⅳ stage patients were (64.5 ± 18.4) min and (61.7 ± 17.1 ) min respectively, which were significantly higher than that of Ⅰ and Ⅱ stage ( ( 31.9 ± 12.3 ) min and (40.3 ± 10. 6) main ] ( t = 20.25, P ＜ 0.01 ). The massive hemorrhages and the internal damage organs occurred in Ⅲ and Ⅳ stage surgery [2.9% and 3.5% ,respectively] ,whereas much less in Ⅰ and Ⅱ stage (0.8% and 1.4% ) ,with no significant difference(P ＞0. 05). After treatment,the rate of symptoms recurrence of Ⅲ and Ⅳ stage patients respectively were 21.4% ,which were higher than that of Ⅰ and Ⅱ stage patients ( 2.3% ) (P ＜ 0.05 )The rate of pregnancy in Ⅲ and Ⅳ stage patients ( 15.4% ) were lower than that of Ⅰ and Ⅱ stage patients (69. 6% ) ( P ＜ 0. 01 ). Conclusions Pelvic EMS decreased the quality of life. EMS patients combined with adenomyosis or/and deep infiltrating EMS have more severe pelvic pain symptoms, less surgical effectiveness and more serious complications. Ⅲ and Ⅳ stage patients are more liable to symptoms recurrence and lower pregnancy rate.

Objective To study the therapeutic effect on murine allergic asthma with recombinant Bla g 2(rBla g 2) allergen and its possible mechanism.Methods Eighteen BALB/C mice were randomly divided into three groups:normal control group(group A) , asthma model group(group B) , and recombinant protein rBlag2 treatment group(group C).Mice in groups B and C were subcutaneously immunized weekly with rBla g 2(50 mg) formulated in Al(OH)3 adjuvant for three weeks.Group A received only adjuvant emulsified with normal saline.Two weeks after the last inoculation, mice in group C were administered each with rBla g 2(100 mg) /dose, and groups A and B were given PBS.All the mice received eight doses at 2-day intervals.One week after the last immunotherapy, mice in groups B and C were intranasally challenged with 50 mg rBla g 2 daily for seven days, while mice in group A received PBS.Twenty-four hours after the challenge, the following items were examined:airway hyperresponsiveness of mice, total cellular score and cell classification in bronchoalveolar lavage fluid(BALF) , level of rBla g 2-specific IgE and IgG2a in serum, lung inflammation by HE stain, and Bcl-2 expression of eosinophils of lung by immunohistochemistry.Results Compared with group B, group C showed a decreased Penh value of airway hyperresponsiveness(P

Objective To study the influence of precision medicine-based health education on cognitive level of disease knowledge,anxiety and depression in patients with gestational diabetes.Methods Toally 84 cases of gestational diabetes patients in our hospital from September 2014 to December 2015 were divided into a study group and a control group according to the random number table,42 cases in each group.While the routine nursing intervention was done in the control group,the precision medicinebased health education program was carried out in the study group.The two groups were assessed using the cognitive questionnaire designed by our hospital.The self rating anxiety scale (SAS) and self rating depression scale (SDS) prepared by Zung were used to assess the levels of anxiety and depression in the two groups before the intervention and two weeks after the intervention.Results The cognitive level of disease knowledge in the study group after the intervention was statistically significantly higher than that of the control group (P＜0.05).Before the intervention,there were statistically insignificant differences in anxiety and depression between the two groups (P＞0.05),but after the intervention,the levels of anxiety and depression in the study group were significantly lower than those of the control group (P＜0.05).Conclusion The precision medicine-based health education is helpful for the patients with gestational diabetes to improve their diabetes-related knowledge and meanwhile it can relieve their anxiety and depression.

Objective:To explore the effect of cholesterol on the expression of genes for matrix synthesis and degradation of human meniscal fibrochondrocytes and its mechanism.Methods:Meniscal tissue was taken from patients undergoing arthroscopic surgery to extract fibrochondrocytes. The cells were divided into a control group in which the normal cells were not processed, a positive control group in which interleukin-1 β was used to create a degeneration model, and 2 treatment groups which were subjected to treatment with 15 and 30 μg/mL cholesterol respectively. Safranin O staining, β-galactosidase staining and enzymic kits were used to detect the morphology and total cholesterol (TCH) content of meniscal fibrochondrocytes in the 4 groups. Immunofluorescence and western blot were used to detect the protein expression of type Ⅰcollagen precursor α1 (COL1A1) and type Ⅱ collagen precursor α1 (COL2A1). RT-qPCR was used to detect the mRNA expression of COL1A1, COL2A1, matrix metalloproteinase (MMP) 3, MMP9, MMP13, and genes related to cholesterol efflux pathways [like liver X receptor α (LXR α), ATP binding cassette transporter A1 (ABCA1) and ABCG1]. Results:There was no significant difference between the control and the positive control groups in the TCH content in human meniscal fibrochondrocytes ( P>0.05). The treatments with 15 and 30 μg/mL cholesterol resulted in significantly increased TCH contents in human meniscal fibrochondrocytes in the treatment groups ( P<0.05). Compared with the control group, the mRNA expression of LXR α, ABCA1 and ABCG1 was significantly decreased in the treatment groups ( P<0.05), and the meniscal fibrochondrocytes in the positive group and the treatment groups presented with a lower density, chaotic distribution and obvious signs of degradation. Compared with the control groups, the mRNA expression of matrix synthesis genes (COL1A1 and COL2A1) in the meniscal fibrochondrocytes was significantly inhibited while the mRNA expression of matrix degradation metalloenzymes (MMP3, MMP9 and MMP13) was significantly promoted ( P<0.05). Conclusion:Cholesterol may inhibit the cholesterol efflux pathways of meniscal fibrochondrocytes, and thus cause accumulation of cholesterol in the meniscal fibrochondrocytes, eventually leading to degeneration of meniscus.

BACKGROUNDThe prevalence of thyroid nodules (TN) is increasing rapidly. This study analyzed the epidemiological and clinical characteristics of TN in surgically treated patients and identified the risk factors for malignant nodules (MN) to provide more understanding of the differential diagnosis of TN.

METHODSA total of 6 304 TN cases who underwent thyroid surgery were included in this retrospective study. The clinical data were collected to evaluate the clinical and epidemiological characteristics and related risk factors for MN. The nature of TN (benign nodules (BN) or MN), medical records, laboratory data, and imaging data were analyzed. The risk factors for MN were screened using Spearman's rank correlation analysis and nonconditional binary Logistic regression analysis.

RESULTSThe number of surgically treated TN cases increased yearly. A total of 34.33% of cases were MN and 65.67% were BN. Up to 56.74% of these cases underwent unnecessary surgery. Among the MN cases, papillary thyroid carcinoma accounted for 94%, in which 46.71% coexisted with benign thyroid disease and 32.28% with multiple foci. Single-related factor analysis showed that age, employment, disease duration, history of breast nodules and/or hypertension, the levels of serum thyroid-stimulating hormone (TSH), thyroglobulin antibody (TgAb), and thyroid peroxidase antibody (TPoAb), and ultrasound features of TN were related to MN. Stepwise nonconditional binary Logistic regression analysis showed that 13 factors may be the independent risk factors for MN, including <40 years old, previous history of breast nodules and/or hypertension, disease duration <1 month, employment, hypoechoic nodule, irregular nodules, nodule calcification, solid echo nodule, fuzzy boundary, rich blood flow within nodules, abnormal lymph nodes around the neck, nodule diameter <1 cm, and abnormally high TgAb.

CONCLUSIONSOur results demonstrate a rapid increase in surgically treated TN cases and ratio of MN and indicate unnecessary surgeries in some cases. This study also suggest that age, duration of thyroid disease, history of breast disease and/or hypertension, the levels of serum TSH, TgAb, and TPoAb, and ultrasound features of TN are related to MN, and some of these factors may be the risk factors for MN.
