Objective: To observe the clinical efficacy of Xingnao-Kaiqiao acupuncture("醒脑开窍"针法) on patients with cerebral infarction.Methods: Sixty-three patients with the disease were randomly divided into treatment group(n=32) treated with Xingnao-Kaiqiao acupuncture and control group(n=31) with(traditional) acupuncture.In addition,routine medicine therapies were given to the two groups(including(dehydration),(decrease) of intracranial pressure,enhancement of nerve nutrition and supportive treatment).(Xingnao-)(Kaiqiao acupuncture) was used and adjusted the number of points with different syndromes in the treatment group,main points were as follows: Neiguan(内关PC6),(Rengzhong)(人中GV26),Sanyinjiao((三阴交)SP6) and vice points were Jiquan(极泉HT1),Chize ((尺泽LU5)),Weizhong(委中BL40),Fengchi(风池GB20),Yintang (印堂EX-HN3),Shangxing((上星DU23)-through-Baihui)(百会GV20).Traditional acupuncture was used in the control group.Points at the upper limbs were Jianjing(肩井GB 21),Quchi(曲池LI 11),Waiguan(外关(S)51),Hegu(合谷LI 4) and at the lower limbs were Zusanli(足三里ST36),Yanglingquan(阳陵泉GB34),Huantiao(环跳GB30),Fenglong(丰隆ST40),Kunlun(昆仑BL60) etc..Acupuncture was given twice a day for 15 days in both groups.Before and after therapy,the hemorrheology,blood lipid,blood,urine,stool and biochemical routine examinations,white blood cell (WBC) count in(peripheral) blood and neurological deficit score(NDS) were(determined).Curative effects of two groups after treatment were observed.Results: After treatment,the total effective power was 93.75% in the treatment group,while it was 67.74% in the control group,the difference being significant (?~2=4.85,P

The effects of testosterone on norepinephrine release were investigated in the isolated rat hearts.Sprague-Dawley male rats (n=120) were randomized to testosterone and control groups.The rats in testosterone group were perfused with modified Krebs-Henseleit buffer containing different concentrations of testosterone (0.1,1.0,10.0,and 100.0 nmol/L,respectively).Myocardial ischemia was induced by globally stopping the perfusion flow.Exocytotic norepinephrine release was induced by electrical field stimulation at 5 V (effective voltage) and 6 Hz (pulse width of 2 ms) for 1 min.The overflow of norepinephrine was determined by high pressure liquid chromatography and electrochemical detection (HPLC-EC).Following acute ischemia,testosterone (1.0,10.0 and 100.0 nmol/L) significantly reduced norepinephrine release (P＜0.01),and the norepinepherine overflow was similar between the control and 0.1 nmol/L testosterone group (P＞0.05).Electrical stimulation of the ventricle evoked norepinepherine release,and this was diminished by the perfusion with testosterone at the concentrations of 1.0,10.0 and 100.0 nmol/L (P＜0.01).It is suggested that testosterone suppresses ischemia- and electrical stimulation-induced norepinepherine release in the isolated rat hearts.

OBJECTIVETo compare villus cell culture and karyotype analysis with single nucleotide polymorphism (SNP) microarray technology for the detection of chorionic villus chromosome in patients with retention of abortion.

METHODSForty cases were analyzed with the two methods.

RESULTSChorionic villus culturing was successful in 29 cases, among which 10 were found to have an abnormal karyotypes. For the SNP microarray analysis, all 40 cases were successful, among which 16 were shown to have an abnormal molecular karyotype.

CONCLUSIONSNP microarray technology is highly accurate and specific, which is particularly suitable for the detection of chromosomal deletions or duplications, uniparental disomy, low-percentage mosaicism and other chromosomal abnormalities. It has provided an effective supplement to the conventional chorionic villus culture and karyotype analysis.

Objective:To verify the clinical value of the good outcome following attempted resuscitation (GO-FAR) score in predicting the neurological status of patients with in-hospital cardiac arrest (IHCA) in the Chinese population.Methods:The clinical data of patients with IHCA who were admitted to the Zigong Fourth People's Hospital from January 1 to December 31, 2020 were retrospectively analyzed. Used Glasgow-Pittsburgh cerebral performance category (CPC) score 1 point as the end point, the subjects were divided into 4 groups according to the score: ≤ 0 group, 1-8 group, 9-20 group and ≥ 21 group. Taken the group which GO-FAR score ≤ 0 as the reference group, the odds ratio ( OR) of the other three groups compared with this group was calculated. The receiver operator characteristic curve (ROC curve) was performed to evaluate the predictive value of the GO-FAR score in favorable neurological outcome. A calibration curve was drawn for the Hosmer-Lemeshow test to analyze the degree of calibration of the GO-FAR score for predicting good neurological outcome. Results:A total of 230 IHCA patients were enrolled in the study, including 130 males, aged 74 (65, 81) years old, and 23 case (10.0%) had good neurological prognosis. There were statistically significant differences in GO-FAR-related variables, including age, a normal neurological function on admitted, acute stroke, metastatic cancer, septicemia, medical noncardiac admission, hepatic insufficiency, hypotension, renal insufficiency or dialysis, respiratory insufficiency, pneumonia, etc (all P < 0.05). Taken the GO-FAR score ≤ 0 group as the reference group, the OR values of good neurological prognosis in the GO-FAR score 1-8 group were 0.54 [95% confidence interval (95% CI) was 0.17-1.53, P = 0.250], 9-20 group were 0.17 (95% CI was 0.02-0.67, P = 0.009) and ≥ 21 group were 0.25 (95% CI was 0.05-0.85, P = 0.025). The area under the ROC curve (AUC) of the GO-FAR score for predicting favorable neurological outcome in IHCA patients was 0.653 (95% CI was 0.529-0.777, P = 0.015) and there was no significant difference in Hosmer-Lemeshow test ( P = 0.311). All these suggested that there was no significant difference between the predicted value and the actual value. Conclusions:GO-FAR score can be applied to predict neurological prognosis of IHCA patients in Chinese population. It can help clinicians to predict the prognosis of cardio-pulmonary resuscitation (CPR) and propose critical recommendations in treatment for these patients or their families.
