Objective To determine the effects of nitroglycerine on cooling and rewarming during cardiopulmonary bypass with deep hypothermic circulatory arrest (DHCAC).Methods Forty-six patients undergoing total aortic arch replacement with DHCAC, 38 males and 8 females, aged 26-74 years, falling into ASA physical status Ⅳ or Ⅴ, were randomly assigned to study group (n=24) and control group (n=22).The same cooling and rewarming methods were implemented in both groups.During cooling and rewarming, the study group received nitroglycerine infusion and the control group normal saline of same volume.The rectum rewarming time, the nasopharyngeal cooling and rewarming time were measured and compared.Results The time of rewarming rectum was significantly shorter in the study group compared to the control group [(104±30) min vs (127±31) min, P<0.05].There was no difference in cooling time , time of rewarming nasopharynx.Conclusion Nitroglycerine shortens the time of rewarming rectum during cardiopulmonary bypass with deep hypothermic circulatory arrest.

Objective To research effects of water extraction of Salvia miltiorrhiza in sperm quality of mice. Methods Forty adult male Kunming mice were randomly divided into 5 groups, including low concentration group, medium concentration group, high concentration group, control group and positive control group in eight mice in each group. The low, medium and high concentration groups were given by gavage with 1 500, 3 000 and 6 000 mg/kg water extraction of salvia miltiorrhiza once a day respectively, while the control group was given gavage with 10 mL/kg normal saline daily, as well as the positive control group was injected with 100 mg/kg cyclophosphamide once; All mice were sacrificed after 30 days. We measured the weight gain, viscera coefficient and sperm quality in each mouse. Results There were no statistical difference in the weight of every week, increase of the weight, testis and epididymis coefficients among the control group, the low, medium and high concentration groups (P > 0.05), while the weight and weight increase were significantly higher than that in the positive control group (P < 0.05). Sperm concentration, viability, morphology, motility, PR, VSL, VAP of low, medium and high concentrations group were significantly improved than the control group (P < 0.05), and the sperm quality in the four groups were higher than that in the positive control group (P < 0.05). Conclusion Water extraction of salvia miltiorrhiza can obviously improve the sperm viability, morphology, and motility of mice.

Familial glucocorticoid deficiency (FGD) is a rare autosomal recessive disease characterized by a single cortisol deficiency and normal aldosterone and renin levels, reported by Shepard et al. in 1959 for the first time. The age of FGD onset may be early or later, from neonatal to adult. The clinical manifestations vary due to the different age at onset. The clinical identification was difficult and would be prone to misdiagnosis because the disease may have many similarities with primary adrenal insufficiency (PAI) caused by other reasons.

OBJECTIVEto observe the effect differences and safety between acupuncture and sham acupuncture for female depression on the basis of conventional western medicine therapy.

METHODSForty-two patients with depression who met the criteria were randomly assigned into an observation group and a control group, 21 patients in each group. The basic treatment in the two groups was fluoxetine. The patients in the observation group were treated with acupuncture at Zhongwan (CV 12), Xiawan (CV 10), Qihai (CV 6), Guanyuan (CV 4) and bilateral Shangqu (KI 17). Sham acupuncture was used at the above points in the control group. The treatment was given once a day on the first 3 days and once every 3 days after that, totally for 8 weeks. The scores of self-rating depression scale (SDS) and Montgomery Asberg depression rating scale (MADRS) were compared before and after 4-week and 8-week treatment in the two groups. The effects and adverse reactions were evaluated.

RESULTSAfter 4-week and 8-week treatment, the SDS and MADRS scores were significantly lower than those before treatment in the two groups (all <0.05), and the scores in the observation group were lower than those in the control group (both <0.05). The improvements of SDS and MADRS scores in the observation group before and after treatment were better than those in the control group (both <0.05). The total effective rates of SDS, MADRS scores were 85.7% (18/21), 90.5% (19/21) in the observation group, which were better than 38.1% (8/21), 57.1% (12/21) in the control group (both <0.05). The adverse reactions in the observation group were significantly lower than those in the control group (<0.05).

CONCLUSIONAcupuncture combined with fluoxetine are effective and safe for female depression.

PSD for evaluating primary synchronous changes in left ventricular myocardial contraction in patients with hypertension has certain advantages .

Objective: To evaluate the clinical performance of HPV genotyping with cytology for detecting cervical precancer among women attending co-testing. Methods: A total of 2 883 females who participated in cervical cancer screening program were recruited from Erdos in 2016. All the participants were tested by cytology and HPV genotyping. In 2017, women with abnormal cytology results or HPV positive were followed up. Pathological cervical intraepithelial neoplasia (CIN) 2+ was the study end-point. Clinical performance indexes were calculated, including sensitivity, specificity, positive predictive value, negative predictive value, referral rate and missed cases. Results: INNO-LiPA resulted in a detection rate of 18.87%(544/2 883) for the 14-type high risk HPV. HPV16 was the most common infectious genotype (4.06%), followed by HPV52 (3.61%), HPV51 (2.50%), HPV58 (1.98%), and HPV18 (1.56%). With more HPV genotypes added into the group, sensitivity increased and the specificity decreased. Addition of HPV16, 58, 33, 39, 52, 18, 31 for detection lead to the maximun value of area under the curve (AUC)=0.913 (95%CI: 0.882-0.944). Compared with traditional screening method by cytology, cotesting decreased the number of missed diagnosis. Meanwhile, the fifth method (co-testing: triage of women with HPV16/18+ , cytological minor abnormalities and HPV58, 33, 39, 52, 31+ or cytological high grade abnormalities) did not increase referral rate (8.99% vs. 8.71%, P=0.525), with five cases of missed diagnosis (sensitivity of 92.1% and specificity of 93.2%). Conclusions Co-testing with triage of women with HPV16/18+ , cytological minor abnormalities and HPV58, 33, 39, 52, 31+ or cytological high grade abnormalities would provide better clinical performance. In co-testing, triage of HPV16/18 was used in women with normal cytology; triage of HPV58, 33, 39, 52 and 31 was used in women with low-grade abnormal cytology; referral colposcopy was used in women with high-grade abnormal cytology, which would provide better clinical performance.
