Objective To study the effect of controlled ovarian Hyperstimulation(COH)on expression of AQP3 mRNA in mouse oocytes at metaphase Ⅱ. Methods Twenty female mice(6-7 weeks) were randomly allocated into 2 groups, mice in COH group were superovulated by intraperitoneal injection of 7.5 IU pregnant mare's serum gonadotropin(PMSG) followed by 5 IU human chorionic gonadotropin(HCG) after 46-48?h. Nothing was given to mice in control group and the estrus cycle was observed at 9?am everyday. 12-16?h following hCG injection (COH group) or at 8?am next day after the estrus (control group), mice were killed by cervical dislocation. The oviducts were excised.Cumulus masses were recovered from the dilated ampullae under a dissecting microscope,digested granulosa cells using hyaluronidase. Semi-quantitative real-time PCR of AQP3 mRNA in mouse MⅡoocytes was investigated with ?-actin as the internal control. Results Oocytes swelling assay showed that AQP3 mRNA expressed in mouse MⅡ oocytes. Using semi-quantitative real-time PCR, the expression of AQP3 mRNA was significantly decreased(P

Objective To analyze the clinical feature, diagnosis and treatment of Alstrom syndrome. Method The clinical data of a case of Alstrom syndrome and the result of her ALMS1 sequencing by the two generation sequencing were retrospectively reviewed. Results The 12 year and 10 month old female suffered from dilated cardiomyopathy, obesity, optic nerve diseases, sensorineural hearing loss, high blood glucose and irregular menstruation since one month of birth. Laboratory examination showed she had high testosterone level, hyperglycemia, hyperlipidemia and fatty liver. High-throughput sequencing confirmed there was ALMS1 gene mutation which includes hybrid frameshift mutations of c.5418delC and p.Y1807Tfs*23, and heterozygous nonsense mutation of c.10549C>T and p.Q3517*, and c.5418delC was a new variation reported for the first time. Conclusion Alstrom syndrome is an autosomal recessive genetic disease, which is characterized by multiple organ dysfunction and metabolic syndrome, and can be diagnosed by gene detection.

Objective:To investigate the effect of peer support education on family function of breast cancer patients with breast reconstruction.Methods:Totally 146 patients who received surgical treatment in the department of plastic surgery for breast cancer from June 2017 to June 2019 were randomly divided into the experimental group and the control group by the method of random number table, 73 cases each. The control group received routine education. Patients in the observation group received regular education and peer support education. The intervention time was from admission to 6 months after discharge, and the control group received routine nursing care. Quality of life questionnaire was used to evaluate the quality of life of the patients at six months after operation, family care index questionnaire was used to evaluate the family function of the patients, and comprehend social support scale was used to evaluate the level of social support, then various indicators of the two groups of patients were compared.Results:6 months after operation, the scores of quality of life function and symptom dimension of the intervention group were 6.43±1.54. 5.83±1.47, while control group were 6.02±1.59; 6.39±1.63. There were statistically significant differences between the two groups ( t values were 4.30, 5.01, P < 0.05); family care scores of the two groups were compared, the intervention group was 8.78±2.04. The control group was 8.43±2.05. There were statistically significant differences between the two groups ( t value was 2.02, P < 0.05); the comprehension support score of the two groups was compared, and that of the intervention group was 62.24±14.81. The control group was 55.74±13.58. There were statistically significant differences between the two groups ( t value was 4.26, P < 0.05). Conclusion:Peer support education can improve the quality of life and family care of breast cancer patients with breast reconstruction.

Objective To study the nursing status of the patients with mechanical ventilation in China. With the reference literature and guidelines, seeking and providing the best evidence and the basis for best practice nursing about mechanical ventilation. Methods We use the convenience sampling method that under the organization and call of the hospital infection nursing professional committee from China nursing association from July to September 2015. 87 hospitals of 13 provinces were selected, and the self-designed questionnaires were used to survey the status of 948 patients with mechanical ventilation. Results For the position management, 26.9% of patients were supine position;69.6% of patients used semireclining position;26.9% of patients had orders about position management. For the oral nursing, 4.0% of patients were 1 times/day;49.7%of patients were 2 times/day;43. 7% of patients were 3 to 4 times/day; 37. 5% of patients used chlorhexidine solution to cleaning the oral cavity;39.3% of patients used normal saline; 84.8% of patients had orders about oral care. For the airbags secretion clean, 78.6% of patients used methods to attract the airbags secretion. For the replace the outside line, 77.8% of patients were 1time/week;5.4% of patients were 1 time/2 weeks;1.1%of patients were 1time/4weeks;3.8% of patients were no indications and no replacement. For the prevention of peptic ulcer, 56.5% of patients used medicine to prevent peptic ulcer. Conclusions Clinical nurses hadn′t achieve unified norms and standards in nursing for patients with mechanical ventilation. There was also existing great gap between guideline recommendations and clinical practice. Currently, the biggest challenge of clinical workers is how to introduce the best evidence to clinic effectively.

Objective:To investigate the drug resistance of patients with acquired immunodeficiency syndrome (AIDS) who failed antiviral therapy.Methods:A total of 156 AIDS patients with antiviral therapy failure at the Sixth People′s Hospital of Zhengzhou from October 2017 to December 2018 were selected. The human immunodeficiency virus (HIV)-1 ViroSeq? genotyping method was used for the detection of HIV resistance, and Stanford University HIV drug resistance database (http: ∥hivdb.stanford.edu/) was used for testing results comparison.Results:Among the 156 AIDS patients with antiviral therapy failure, 122(78.21%) developed drug resistance. One hundred and six (67.95%) cases were multi-resistant to nucleoside reverse transcriptase inhibitor (NRTI), among which, 104 (66.67%) were resistant to lamivudine, emtricitabine and abacavir. One hundred and eighteen (75.64%) were resistant to non-nucleoside reverse transcriptase inhibitor (NNRTI), and 118 (75.64%) were multi-resistant to efavirenz and nevirapine. And seven (4.49%) were resistant to protease inhibitor (PI). There were 16 resistant sites for NRTI, with 87 (71.31%) most frequent M184V/I mutations. There were 13 resistant sites for NNRTI, with 49 (40.16%) K103N/R mutations. There were 11 resistant sites for PI, with 49 (40.16%) A71V/T mutations. The antiviral drugs lamivudine and emtricitabine were moderately and highly resistant in 102 (83.61%) cases, efavirenz and nevirapine were moderately and highly resistant in 117 (95.90%) cases. Once drug resistance developed, these drugs were likely to be moderate or high resistance. There were 29 (23.77%), 48 (39.34%), and five (4.10%) cases were resistant to zidovudine, tenofovir and lopinavir/ritonavir, respectively. The resistance barrier of these drugs was relatively high.Conclusion:The incidence of drug resistance in patients with AIDS treatment failure is high, and multi-drug resistance is serious with various sites of drug resistance.

Objective To investigate the self-care agency in disabled elders of community and to explore effects of medical care and nursing service integration on self-care agency in disabled elders with different degrees of disability in community. Methods We traced and investigated a total of 42 disabled elders signed medical care and nursing service integration with a community. The self-care agency was compared with the Chinese Version of the Self-care Ability Scale for the Elderly (SASE-CHI) before and six months after service objects accepting services. Results The average of self-care ability of community disabled elders was (48.69±12.11) with a low level. Six months after accepting medical care and nursing service integration, the score of self-care ability of disabled elders increased along with (53.07±8.68) in total score of self-care ability, (21.38±3.76) in objective dimension and (25.62±4.39) in skill dimension. There were significant differences in scores of self-care ability compared before and after accepting service (t=-2.346,-2.592, -2.731;P<0.05). There were small changes in elders with mild disability before and after accepting services (P>0.05). The total score of self-care ability and score of skill dimension increased in elders with moderate and severe ability after accepting services, the differences were statistically significant (P<0.05). Conclusions The self-care ability of community disabled elders is in a low level. The medical care and nursing service integration can improve self-care ability of community disabled elders. However, there is great room to upgrade.
