RESUMO
Objective:To investigate the efficacy of gonadotropin releasing hormone agonist (GnRH-a) combined with a levonorgestrel-releasing intrauterine system (Mirena) in patients with adenomyosis and its effects on ovarian function, carbohydrate antigen (CA) 125, CA153 and carcino-embryonic antigen (CEA) expression.Methods:Seventy-eight patients with adenomyosis who received treatment from September 2017 to September 2020 in Shaoxing People's Hospital were included in this study. They were randomly divided into treatment and control groups ( n = 39/group). Patients in the control group were treated with a levonorgestrel-releasing intrauterine system. Patients in the treatment group were treated with GnRH-a, once per month in the first 3 months based on treatment with a levonorgestrel-releasing intrauterine system. After 6 months of treatment, changes in dysmenorrheal relief, menstrual volume, uterine volume, endometrial thickness, ovarian function, CA125, CA153 and CEA levels relative to before treatment were compared. Results:Visual analog scale score and pictorial blood assessment chart score in the treatment group were (1.36 ± 0.28) points and (38.98 ± 5.42) points, which were significantly lower than those in the control group [(1.78 ± 0.31) points, (63.42 ± 6.75) points, t = 6.27, 17.63, both P < 0.05). Uterine volume and endometrial thickness in the treatment group were (209.74 ± 15.65) cm 3 and (7.37 ± 0.57) mm, respectively, which were significantly lower than those in the control group [(278.39 ± 20.90) cm 3, (8.63 ± 0.86) mm, t = 16.45, 7.62, P < 0.05]. There were no significant differences in serum levels of luteinizing hormone, follicle stimulating hormone and estradiol between the two groups (all P > 0.05). Serum CA125, CA153 and CEA levels in the treatment group were (26.87 ± 7.21) U/L, (23.12 ± 7.38) U/mL and (5.45 ± 0.96) μg/L, respectively, which were significantly lower than those in the control group [(49.93 ± 8.97) U/L, (38.94 ± 6.21) U/mL, (8.23 ± 1.35) μg/L, t = 12.51,10.24,10.48, P < 0.05]. Conclusion:GnRH-a combined with a levonorgestrel-releasing intrauterine system (Mirena) can markedly relieve dysmenorrhea, reduce menstrual volume, uterine volume, and endometrial thickness, has no obvious effects on ovarian function, and greatly reduce the levels of CA125, CA153 and CEA. Therefore, the combined method is a safe and effective non-surgical treatment method of adenomyosis.
RESUMO
Objective:To explore the clinical significance of biopsy pathological examination of cervical cytology negative, high-risk human papillomavirus (HPV) positive.Methods:The pathological data of cervical biopsy in 220 patients with cytological negative, HPV16/18 positive or interval of 1 year other 12 high-risk HPV (12HR-HPV) lasting positive for more than 1 year from January 2014 to May 2019 were retrospectively analyzed.Results:Of 220 patients, there were 3 cases with adenocarcinoma, 18 cases with CINⅢ, 18 cases with CINⅡ, 69 cases with CINⅠ, 47 cases with condyloma-like lesions, 65 cases of chronic inflammation.Among 36 cases of high-grade squamous intraepithelial lesions, there were 35 cases with HPV16/18 positive, accounting for about 15.91%(35/220), and only 1 case of other 12 high-risk HPV was continuously positive for more than one year, accounting for 0.45%(1/220).Conclusion:Cervical cytological screening may appear false negative, high-risk HPV typing examination may be more able to detect cervical intraepithelial lesions, for cytological negative, high-risk HPV positive, especially HPV16/18 positive, immediate referral colposcopy can reduce the missed diagnosis of cervical high-grade squamous intraepithelial lesions and even cancerous.

RESUMO
Objective To explore the influence of Neuman theory on postoperative mental status of the patients with hypertensive cerebral hemorrhage. Methods According to their admission order, 120 patients with hypertensive intrac-erebral hemorrhage who accepted operation in our hospital from June 2011 to January 2014 were divided into the ex-perimental group and the control group, each group with 60 patients. The patients in the control group were treated with routine care while the patients in the experimental group were given psychological care interventions designed in ac-cordance with Neuman theory on the basis of the routine care. The nursing effects of the two groups were compared, detected and evaluated by Hamilton Depression Rationg Scale (HAMD) and Self-reporting inventory (SCL-90). Results The differences of HAMD total score of the two groups before interventions were not statistically significant. After 12 weeks intervention, HAMD total score of the experimental group significantly improved, especially in hopelessness, anxiety/somatization and cognitive impairment. The depression, anxiety, obsessive-compulsive symptoms, horror, hostility and psychosis of the experimental group were significantly lower than those of the control group after 12 weeks inter-vention. Conclusion Neuman theory has very high value of application to improve postoperative psychological status of the patients with hypertensive cerebral hemorrhage and is worthy of being promoted and applied in clinical work.
RESUMO
We used a meq-deleted attenuated MDV-I strain GX0101Δmeq as a vector to construct a recombinant virus expressing the exogenous gene NDV-F. The ORF of exogenous gene NDV-F was inserted into the eukaryotic expression vector pcDNA3.1(-). Then, the expression cassette of NDV-F which contains the CMV promoter was amplified. Simultaneously, we amplified the selected gene Kan+ expression cassette and inserted them into the PMD18-T vector. Tandem expression cassettes were amplified using primers containing the 50-bp homologous arm of MDV-US2. The PCR product was electroporated into EL250 host bacteria containing GX0101Δmeq. Then, the Kan+ expression cassette was deleted from the recombinant virus genome using 1% arabinose. The plasmid of the positive clone which the Kan+ expression cassette was deleted was extracted and transfected into CEFs to rescue the recombinant virus. The recombinant virus was injected into chickens to observe its growth and replication. The recombinant virus rMDV-F containing the exogenous gene NDV-F was rescued successfully. The recombinant virus could duplicate and express well in CEFs, and grow and replicate well in chickens. Using GX0101Δmeq as a vector, combined with a recombinant system of Red E/T and FLP/FRT, we constructed a recombinant virus that expressed the exogenous gene NDV-F. This study could lay the foundation for further study of recombinant viruses.
