The changes of calcium and magnesium content in brain tissue (BCa;BMg) and in the mitochondria (MCa,MMg) and calmodulin content in the cortex and hippocampus (CCaM,HCaM) were determined in the rats with 4-vessel-ligation cerebral ischemia.And then the therapeutic effects of nimodipine were observed during ischemic and.reperfusion stages of the brain.It was found that BMg and BMg were decreased and CCaM HCaM increased during both the ischemic and reperfusion stages and BCa and MCo were increased during the reperfusion stage.The fact that calcium content was only increased during the reperfusion stage indicates that the influx of calcium plays an important role to precipitate injury during the reperfusion stage.Adminstration of nimodipine could prevent the increase of calcium and calmodulin and the decrease of magnesium after cerebral ischemia.

Objective To evaluate the clinical efficacy of four different operative patterns of laparoscopic hysterectomy: laparoscopically assisted vaginal hysterectomy (LAVH), laparoscopically introfasial subtotal hysterectomy (LISH), laparoscopically subtotal hysterectomy (LSH) and laparoscopically total hysterectomy (LTH). Methods A retrospective analysis on 2272 cases of laparoscopic hysterectomy was carried out, including operating time, blood loss, complication and postoperative recovery. Results For the two groups which preserved cervix, LISH was performed in 1323 cases. The operating time was (91?21) min, blood loss (93?23) ml, complication rate 4.1%. LSH was conducted in 229 cases, with an operating time (70?18) min, blood loss (69?17) ml, complication rate 0. The difference between the two groups was significant (all P0.05). All patients recovered well postoperatively. Conclusions The four operative patterns are ideal for hysterectomy. Young patients should be operated with laparoscopic hysterectomy with preservation of cervix, old patients or patients with CIN should be operated with excision of cervix.

Objective To explore the value of laparoscopic operations for early-stage cervix cancer. Methods Eighteen patients with Ⅰ b～Ⅱ a astage cervix cancer underwent extensive total uterectomy combined with pelvic lymphadenectomy under laparoscope (17Ⅰ b cases, 1Ⅱ a case). Concurrently, another 19 patients with the same diagnosis and approximately the same clinical features as the abovementioned 18 cases, as the control group, were treated by open extensive total uterectomy combined with pelvic lymphadenectomy. The operation time, intraoperative blood loss, postoperative recovery and complications of two groups were compared. Results No statistically significant differences were found on mean operation time between the laparoscopy group (272.8 min?80.3min) and open group (226.5 min?66.8min) (t=1.921,P=0.063). The number of removed lymph nodes was 15.6?5.1 in laparoscopy group and 16.8?5.7 in open group, without statistically significant differences (t=0.674,P=0.505). The recovery time of intestine functions in laparoscopy group (34.2 hours) was obviously shorter than that of open group (60.7 hours) (P

Objective To detect CD_(36) expressions in polycystic ovary (PCO), and to explore its correlation with local androgen and insulin at transcription level. Methods From August 2002 to February 2003, 12 patients with asymmetric PCO, 15 primary or secondary infertile patients without endocrine disorders and 8 polycystic ovary syndrome (PCOS) with bilateral PCO were recruited. Extraction of follicular fluid and detection of testosterone(T), dehydroepiandrosterone sulfate (DHEAS), insulin (INS) and androstenedione (A_2) were performed. Relative CD_(36) mRNA expression level of human ovarian inner thecal cells was analyzed by auto image analysis system (IAS) after RT-PCR. Results The level of CD_(36) mRNA expression in thecal cells was 0.24?0.07 in polycystic ovary of PCO group and 0.21?0.05 in bilateral ovaries of PCOS group, respectively, which were significantly lower than 0.83?0.13 in normal ovaries (P

Objective To explore the differences of emotion identification and emotion quotient (EQ) scores between the teenage criminal group and the vocational school student group,and conduct research on the correlation between the emotion identification and EQ of teenage criminals.Methods A self-designed questionnaire,experiments about emotion identification and EQ tests were applied to 48 teenage criminals and 46 vocational school students who had the matching age,IQ and sex with the teenage criminals.Results The number of correct responses to neutral mood among the teenage criminals (60.00± 17.07) was lower than that of vocational school students (66.12±5.45).There was no difference about EQ between these two groups(90.48± 13.31,90.76± 19.85,P ＞0.05),but in pressure management dimensions,teenage criminals had some differences compared with the vocational school students (53.97± 8.95,57.84 ± 7.26,P＜ 0.05),especially in impulse control (24.97 ± 4.98,28.95 ± 5.22,P＜0.01).The general state of mind,pressure management,individual components and interpersonal components was related to the emotion identification(r 1 =0.43,r 2 =0.36-0.38,r 3 =0.37,P＜0.05).Conclusion Emotion identification of teenage criminals have some flaws,especially the judgment on neutral mood,and it is easily to be wrong.Teenage criminals lack of controlling in EQ.The emotion identification and EQ of the teenage criminal interact with each other.

Objective To explore the characteristics of emotional identification and emotional intel-ligence of the adolescent methamphetamine addicts,and analyze the correlation between the emotional identi-fication and emotional intelligence.Methods 47 adolescent methamphetamine addicts ( experimental group) and 47 healthy volunteers ( control group) were tested by a self-designed questionnaire,Baron Emo-tional Quotient Inventory ( EQ-i) and experiments of emotional identification.Results The scores of correct responses of positive mood and negative mood of the adolescent methamphetamine addicts ( respectively 28.62±10.60,50.83±18.58) were lower than the healthy volunteers (respectively 32.91±7.30, t=-2.29, P<0.05;62.47±15.75, t=-3.28, P<0.01) .There were significant differences on the sense of responsibility ( re-spectively 33.28±3.79,36.47±4.31;t=-3.81, P<0.01) and impulse control ( respectively 24.81±6.03,30.11 ±5.65;t=-4.40, P<0.01) between the adolescent methamphetamine addicts and the healthy volunteers. While there was no difference on the total score of emotional intelligence between the two groups( t=-0.66, P>0.05) .In the dimension of emotional intelligence,the individual components,the general state of mind,the management of pressure,and the adaptive composition were related to the emotional identification( r 1=0.39, r 2=-0.33, r 3=-0.39, r 4=0.32) .Conclusion The adolescent methamphetamine addicts had some de-fects on the emotional identification and lack of responsibility and impulse control ability.The emotional in-telligence had influence on their emotional identification.

Objective:To explore the characteristics of working memory ability of female methamphetamine dependent youths, and to analyze the effect of spatial and temporal training task (CODING) on working memory ability of female methamphetamine dependent youths.Methods:Sixty methamphetamine dependent youths from a women's drug rehabilitation center in Sichuan province were selected as the methamphetamine dependent group, while 60 female healthy volunteers from vocational high schools and universities participated as the healthy control group. Visual memory test (VISGED) was used to evaluat the working memory ability of the subjects, and SPSS 21.0 software was used for the nonparametric test of the memory difference between the two groups.The methamphetamine dependent group was divided into treatment group and waiting group based on the baseline matching principle of working memory. The treatment group was trained under the spatio-temporal CODING paradigm for working memory, and the training effect was assessed using the independent sample t-test. Results:(1)The individual parameters(0.06(-1.62, 1.67) vs 1.93 (-0.28, 2.71)) and working program(15.00(14.00 vs 16.00), 17.00(15.00, 20.00)) of working memory in methamphetamine dependent group and normal control group were statistically significant ( Z=-3.83, P<0.05, Z=-3.50; P<0.05). (2) Through memory training, the personal parameters before and after training in the treatment group ((0.08±1.79) vs 1.68 (0.68, 2.25)) had a statistically significant difference ( Z=-3.63, P<0.05). The personal parameters before and after the test in the waiting group ((-0.01±1.86) vs 0.72(-1.54, 1.88)) had no statistically significant difference ( Z=-1.35, P>0.05). Conclusion:Methamphetamine dependence impaire the working memory of female youths regardless of age or education level. Memory training can restore and improve memory ability to a certain extent, help to restore learning ability and living ability, and lay a foundation for a better return to society.

Objective:To explore the effect of methamphetamine (MA) dependence on the attention of female youth, and to analyze the intervention effect of computer-based cognitive training on the attention of MA-dependent female youth.Method:From May to August 2021, a total of 64 MA-dependent female youths in abstinence period from a women's compulsory isolated drug rehabilitation center in Sichuan Province were selected as the MA group, and 53 ordinary female youths matched with their age and education level were selected as the normal control group.According to the matching principle of age, education level, and attention pre-test scores, the subjects in MA-dependent group were divided into MA-dependent intervention group( n=30)and MA-dependent waiting group( n=34). CogniPlus cognitive training system was used to train the attention of subjects in MA-dependent intervention group( n=30), while the subjects in MA-dependent waiting group( n=34) and normal control group did not receive training.The Vienna Test System was used to collect the attention scores of all subjects.SPSS 20.0 analysis software was used for data processing.Statistical analysis was performed using independent samples t test and paired samples t test. Results:The MA-dependent group had significantly longer endogenous alertness, temporary alertness, and concentration response time ((275.61±47.79)ms, (268.63±51.41)ms, (444.08±134.40)ms) compared with the normal control group ((247.02±34.09)ms, (237.60±46.04)ms, (355.15±44.37)ms) ( t=3.767, 3.405, 4.976; all P<0.05). After attention training, the post-test reaction time of endogenous alertness, temporary alertness, and concentration ((264.10±38.98)ms, (251.67±38.06)ms, (352.03±65.70)ms) in the MA-dependent intervention group were significantly shorter than those in the MA-dependent waiting group ((323.18±83.28)ms, (302.74±82.75)ms, (402.76±74.34)ms) ( t=-3.702, -3.232, -2.876; all P<0.05). The post-test reaction time of temporary alertness and concentration in the MA-dependent intervention group ((251.67±38.06)ms, (352.03±65.70)ms)were shorter than those of the pre-test ((265.70±37.84)ms, (428.67±120.11)ms) ( t=2.179, 3.588; both P<0.05). The MA-dependent waiting group had a longer post-test reaction time of endogenous alertness and temporary alertness(323.18±83.28)ms, (302.74±82.75)ms) compared with the pre-test ((285.35±51.43)ms, (271.21±61.42)ms) ( t=-2.752, -2.664; both P<0.05) and the post-test reaction time of concentration ((402.76±74.34)ms) was shorter than that of the pre-test ((457.68±146.29)ms)( t=2.431, P<0.05). The MA-dependent intervention group had longer endogenous alertness, temporary alertness, and pre-test reaction time of concentration ((264.57±41.41)ms, (265.70±37.84)ms, (428.67±120.11)ms)compared with the normal control group( t=2.083, 2.841, 3.230; all P<0.05). The post-test of endogenous alertness ((264.10±38.98)ms) was longer than that of the normal control group ( t=2.082, P<0.05). Conclusion:The cognitive training based on the CogniPlus system has a certain effect on the attention maintenance or recovery of MA-dependent female youth.It can be used as an intervention measure for cognitive impairment of drug addicts and help them healthy return to society.
