ABSTRACT
Objective@#To investigate the effect of NACHT-LRR-PYD- containing proteins 3 (NLRP3) mediated pyroptosis in myocardial cells undergoing hypoxia/deoxygenation (H/R) injury.@*Methods@#In order to observe whether H/R-treatment could cause pyroptosis, H9c2 cells were divided into 2 groups randomly using the lottery method: control group(without H/R-treatment) and H/R group (in which the H9c2 cells were underwent H/R-treatment). In order to clarify the role of pyroptosis in H/R-injury, H9c2 cells were divided into 4 groups randomly using the lottery method: control group(in which the H9c2 cells were cultivated with normal medium); YVAD group(in which the H9c2 cells were pretreated with z-Val-Ala-Asp(Ome)-fluoromethylketone (Z-YVAD-FMK) 20 μm for 4 hours, then replaced with normal medium); H/R group(H9c2 cells underwent H/R-treatment); YVAD+H/R group (in which the H9c2 cells were pretreated with 20 μm Z-YVAD-FMK for 4 hours before H/R-treatment). To determine whether H/R-induced cell pyroptosis is associated with NLRP3, H9c2 cells were divided into 4 groups randomly using the lottery method: control group (in which cells were transfected with a control nonspecific siRNA); si-NLRP3 group (in which cells were transfected with NLRP3-targeting siRNA); H/R group(in which cells were transfected with a control nonspecific siRNA before H/R-treatment); si-NLRP3+H/R group(in which the H9c2 cells were transfected with NLRP3-targeting siRNA before H/R-treatment). Pore formation on cell membrane was detected by propidium iodide (PI) staining. Cell viability was detected by CCK8 reagent. The protein expression of Caspase-1, interleukin-1β (IL-1β) and NLRP3 was detected by Western blot.@*Results@#(1) The positive rate of PI staining ((26.46±5.15)% vs. (1.69±0.73)%,P<0.01), expression of NLRP3 (0.57±0.16 vs. 0.23±0.06,P<0.01), expression of Caspase-1 (1.07±0.13 vs. 0.37±0.08,P<0.01), and expression of IL-1β (0.38±0.08 vs. 0.16±0.05,P<0.01) were significantly higher in H/R group than in control group. (2)The cell vitality was significantly higher in YVAD+H/R group than in H/R group ((87.31±9.05)% vs. (73.30±7.19)%, P<0.05).The positive rate of PI staining was significantly decreased in YVAD+H/R group than in H/R group ((18.12±4.36)% vs. (26.45±4.60)%, P<0.05). The expression of Caspase-1 (0.72±0.12 vs. 1.07±0.15, P<0.05) and IL-1β(0.29±0.07 vs. 0.39±0.06, P<0.05) were significantly lower in YVAD+H/R group than in H/R group. (3) The cell vitality was significantly increased in si-NLRP3+H/R group than in H/R group ((85.46±7.71)% vs. (72.41±5.53)%, P<0.05). The positive rate of PI staining was significantly lower in si-NLRP3+H/R group than in H/R group ((18.22±4.20)% vs. (26.73±3.26)%, P<0.05). The expression of Caspase-1(0.87±0.07 vs. 1.15±0.15, P<0.05) and IL-1β(0.41±0.07 vs. 0.58±0.10, P<0.05) were significantly decreased in si-NLRP3+H/R group than in H/R group.@*Conclusion@#NLRP3 mediated pyroptosis is involved in H/R injury of myocardial cells.
ABSTRACT
@#【Objective】 To investigate the relationship between the expression of PRDX3 （thioredoxin-dependent peroxide reductase）and the occurrence and development of ccRCC （clear cell renal cell carcinoma）. 【Methods】 The expression of PRDX3 was first verified in 16 cases of ccRCC tissues and adjacent normal tissues. In the present study ， according to the PRDX3 over-expression level，we established the stable PRDX3 overexpression cell lines and knockdown cell lines in 786-O cell lines. We detected the growth rate of tumor cells after overexpression and knockdown of PRDX3. Interaction proteins with PRDX3 were searched by anti-flag pull-down test combined with LC- MS/MS technique. The interaction between PRDX3 and PRDX1（peroxiredoxin 1）was preliminarily explored.【Results】The western blot results showed that PRDX3 were down- regulated in 14 out of 16 ccRCC tissue samples about 1.78 times. Stable PRDX3 overexpression and knockdown cell lines and those control group were successfully established［786O- PRDX3（+）and 786O- PRDX3（-），786O- PRDX3 KN and 786O- PRDX3 NCi］. PRDX3 expression in 786O- PRDX3（+）was 2.1 times higher than 786O- PRDX3（-）at mRNA level and 1.8 times at protein level. PRDX3 expression in 786O- PRDX3 KN was 0.48 times lower than 786O-PRDX3 NCi at mRNA level and 0.51 times at protein level. The cell growth rate of 786O-PRDX3 （+）cell lines was significantly lower than that of 786O-PRDX3（-）. Meanwhile ，there was no significant difference in 786O-PRDX3 KN and NCi cell lines. Pull-down results shows that PRDX3 may interact with PRDX1 through disulfide bond and the binding sites of those two proteins were identified respectively.【Conclusion】PRDX3 was down- regulated expression in renal clear cell carcinoma and the interaction with PRDX1 may be involved in the occurrence and development of tumor. Increasing the expression level of PRDX3 can significantly reduce the growth rate of tumor cells. Based on PRDX3 ，it is possible to develop targeted drugs for treating renal clear cell carcinoma.
ABSTRACT
Objective@#Practice of setting up campus clinics in school,to explore adolescent outpatient service mode to better meet the diversified demands of teenagers,and to promote more effective implementation of adolescent health care.@*Methods@#Campus-based adolescent outpatient clinics were established in 2 universities in Chongqing,a questionnaire survey was conducted among 136 students who participated in the consultation, campus-based outpatient services and adolescents’ satisfaction towards the services were analyzed. Hospital adolescent outpatient services were compared before and after the establishment of campus adolescent clinic.@*Results@#Most of adolescent outpatient clinic in hospitals offered disease-based treatment instead of consultation. The overall satisfaction rate was 94.85%, and the satisfaction towards service ability, communication skills, outpatient time arrangement, and privacy protection was 96.32%, 96.32%, 88.97% and 94.12%, respectively. After the establishment of campus adolescent outpatient clinics, adolescent outpatient services in hospital increased dramatically including consultation.@*Conclusion@#It is necessary to offer adolescent outpatient services in schools, which are more helpful for the diversified demands of teenagers.
ABSTRACT
OBJECTIVE@#To investigate the caries status of the first permanent molars in urban and rural children aged 10- 12 in Chongqing and analyze the related factors in order to provide a theoretical basis for the prevention and treatment of children's caries and targeted suggestions for oral health education.@*METHODS@#A multi-stage, stratified, cluster, and random sampling method was used to extract 5 057 children from 18 schools in three districts and three counties in Chongqing for oral health examination and questionnaire survey from March to May 2018.@*RESULTS@#The total caries rate of the first permanent molar was 39.2%. The decayed-missing-filled tooth was 0.84±1.20. The rate of filling teeth was 3.4%. The rate of pit and fissure sealing was 6.1%. The prevalence of the first permanent molars was significantly different between men and women, between urban and rural areas, between only children and non-only children, and between ethnic minorities and Han nationality (P<0.001). The gap between the pit and fissure sealing was significantly different between urban and rural areas (P< 0.001). Multiple logistic regression analysis showed that many independent factors influence the occurrence of caries, including the frequency of brushing teeth every day, the frequency of eating desserts, the habit of eating dessert/drinking milk before going to bed, whether only-children or not, and parents' education background, among others.@*CONCLUSIONS@#The first permanent molars of children aged 10-12 in Chongqing have a high rate of caries but low rates of pit and fissure sealing and dental caries filling. The difference between urban and rural areas is large, children's oral health knowledge is scarce, and children have bad oral hygiene behaviors and eating habits. Children's oral health education must be strengthened, oral health preaching must be implemented in schools, the oral health knowledge of children in school must be improved, and urban-rural differences must be minimized.

ABSTRACT
There are some problems in the teaching of medical physics course,such as low learning initiative,deficient grasp of concept,and obstacles to realize the internalization and practical application of knowledge.The PAD (presentation-assimilation-discussion) class is applied in the course,in order to improve the students' learning state.PAD class is a teaching mode proposed from a psychological point,which advocates that teaching is the first before students start to learn and has an equal treatment on students' discussions and teachers' instruction,supporting independent learning.The teaching measures include:selecting course content to reach the balance between simplification and detailed interpretation;assigning open homework based on the course;dividing the class discussion into four steps;assessing students based on the performances of homework and final examinations.The research has shown that the PAD class facilitates improving the students' initiative of study and promoting the absorption and application of knowledge.
ABSTRACT
Neural oscillation is rhythmic or repetitive neural activity in the central nervous system that is usually generated by oscillatory activity of neuronal ensembles, reflecting regular and synchronized activities within these cell populations. According to several oscillatory bands covering frequencies from approximately 0.5 Hz to >100 Hz, neural oscillations are usually classified as delta oscillation (0.5-3 Hz), theta oscillation (4-12 Hz), beta oscillation (12-30 Hz), gamma oscillation (30-100 Hz) and sharp-wave ripples (>100 Hz ripples superimposed on 0.01-3 Hz sharp waves). Neural oscillation in different frequencies can be detected in different brain regions of human and animal during perception, motion and sleep, and plays an essential role in cognition, learning and memory process. In this review, we summarize recent findings on neural oscillations in hippocampus, as well as the mechanism and function of hippocampal theta oscillation, gamma oscillation and sharp-wave ripples. This review may yield new insights into the functions of neural oscillation in general.
ABSTRACT
Objective To compare the effectiveness and safety of continuous and intermittent ice compression therapy following total knee arthroplasty surgery. Methods Eighty patients were divided into two groups receiving continuous or intermittent 30 minutes every 2 two hours within 48 hours after the operation. The subjective pain (VAS score), additional pain-killer use, swelling of extremity, drainage, range of motion were observed and compared. Results Patients in the observation group had less pain than those in the control group (Z values in the first 3 postoperative day was-2.722,-3.359,-2.039, respectively, P<0.05). Less pain-killers were required in the experimental group (Z=-2.559, P<0.05). The postoperative swelling by the thigh circumferences in the first day in the observation group was (1.84 ± 1.11) cm, which was milder than the (3.30 ± 1.69) cm of the control group (t=4.565, P<0.01). So was it in the calf circumferences, (0.94 ± 0.89 ) cm vs. (1.46 ± 0.91) cm (t=2.627, P=0.01). Within the first 3 days after the operation, this mildness still existed in aspect of thigh circumferences, which was (3.09±1.39) cm in the observation group vs the (4.09 ± 1.71) cm in the control group, t=2.869, P < 0.01. Conclusions Continuous ice compression therapy has better effects than intermittent 48 hours after total knee replacement, with functional training and exercise not disturbed. It is considered safe and assured, and is therefore recommended.
ABSTRACT
OBJECTIVE:To provide reference for rational drug use in respiratory department. METHODS:ADR/ADE report-ed by respiratory department of a class three grade A hospital during Jan. 2011 to Dec. 2015 from national ADR monitoring system were collected. 2011-2015 ADR/ADE database of respiratory department in a hospital was established and analyzed statistically. RE-SULTS:202 records were gotten,among which 89 cases were male(44.06%)and 113 cases were female(55.94%);the patients’ age approximated normal distribution,the incidence of ADR/ADE was the highest in 61-80 age group (55.94%);the occurrence time of ADR/ADE was mostly lower than 1 h (47.21%);the main route of administration was intravenous drip (71.29%);22 kinds of drugs were involved,and antibiotics took up the lead(43.11%);84 patients(41.58%)used 2 and more kinds of drugs before the occarrence of ADR/ADE;organs/systems involved in ADR/ADE were skin and its appendants (32.86%) and digestive system(26.19%). Most of the ADR/ADE could be cured or recovered after related treatment. CONCLUSIONS:The occurrence of ADR/ADE in respiratory department is related to various factors,of which advanced age,intravenous administration and antibiotics use are important ones. Great importance should be attached to rational clinical drug use as well as ADR/ADE monitoring and re-porting. Clinical also should pay attention to the safety of drug use in elderly patients.

ABSTRACT
ABSTRACT:Objective To a rare case of double primary cancer (hepatocellular carcinoma with gallbladder)to guide clinical application.Methods and Results We reported one case of primary hepatocellular carcinoma and gallbladder.A male patient,54 years old,had main complaints of intermittent right upper quadrant pain for 4 days. The abdominal CT of the local county hospital showed gallstones,gallbladder with liver infiltration.And then he went to the First Affiliated Hospital of Xi’an Jiaotong University for further treatment.Laboratory examination revealed:HBsAg(+),HBcAb(+),alpha-fetoprotein (AFP)> 60 500 ng/mL,carcinoembryonic antigen (CEA) 5.25 ng/mL.Abdominal CT showed hilar slightly stronger light echo groups:liver cancer or gallbladder cancer? Hepatic artery and portal vein CT imaging (CTA+CTV)examination showed the malignant tumor shadow in the inside of the left hepatic lobe huge,uneven thickening of the gallbladder wall,suspected liver disease with gallbladder infringement or gallbladder disease with liver infringement. With the preoperative preliminary consideration of primary liver cancer with infiltration of the gallbladder,we chose the operation as the resection of segment Ⅳ b and Ⅴ of the liver,cholecystectomy and T tube drainage.Pathological examination postoperative showed the bulky liver carcinoma grade Ⅲ and the poorly differentiated adenocarcinoma of gallbladder.A month later,abdominal CT showed the tumor spread intrahepatic,prompting the poor prognosis.Conclusion The two which are not continuous,which is the standard of double primary cancer,are not suitable for all double primary cancers.This case provides useful experience for future similar diagnosis and treatment of disease,and also helps us with timely and accurate identification of “metastatic”or “primary”,which is the key point for clinicians to give patients an effective treatment.
ABSTRACT
Objective To study the effect of electrical stimulation of the fastigial nucleus of the cerebellum (FNS) on learning,memory and the expression of growth-association protein-43 (GAP-43) after cerebral ischemia and reperfusion.Methods Sixty healthy,adult,male Sprague-Dawley rats were randomly divided into a normal group,a sham-operation group (sham group),a model group and an FNS group,with 15 rats in each.Left middle cerebral artery occlusion and reperfusion (MCAO/R) was administered to the rats in the FNS and model groups using the thread embolism method.The rats of the FNS group were given FNS treatment using a pair of needle electrodes inserted into the cerebellar fastigial nucleus 3hrs after the MCAO/R.Needle electrodes were similarly inserted in the model group rats,but no electrical stimulus was applied.Then the rats' learning and memory abilities were tested using a Morris water maze on days 1,3 and 7 after the MCAO/R modeling.The expression of GAP-43 mRNA on the side of the cerebral infarction was detected using a quantitative,real-time polymerase chain reaction.Results The average escape]atencies of the rats in the model and FNS groups were significantly longer than those of the normal and sham groups at all time points,but the FNS group rats demonstrated a significantly shorter average escape latency than the rats of the model group at each time point.The normal and sham groups showed a significantly lower expression of GAP-43 mRNA than the model and FNS group rats at all time points.The FNS group rats had a significantly higher level of GAP-43 mRNA than the rats of the model group.Conclusion FNS improved the rats' learning and memory abilities.This might be associated with the up-regulation of GAP-43 mRNA in neurons on the side of the cerebral infarction which could promote the regeneration and repair of peripheral nerve axons in the area of the infarction.

ABSTRACT
Purpose To explore the diagnostic value of double exponential model for pelvic lesions using 3.0T MRI for the diagnosis of pelvic lesion. Materials and Methods Fifty patients with pelvic lesions (30 benign cases and 20 malignant cases) underwent MR750-diffusion weighted imaging (DWI) scans, with b values of 0, 50, 300, 600, 800 and 1200 s/mm2, Functool-MADC software was used on AW 451 workstations for data processing, Slow ADC value, Fast ADC value, Standard ADC value, Fraction of fast ADC value were recorded and compared between benign and malignant lesions, and Standard ADC images were fused with axial T2 fat-suppressed images. Results Slow ADC values [(1.83±0.86)×10-3 mm2/s] and Standard ADC values [(1.79±0.78)×10-3 mm2/s] of benign lesions were larger than those of the malignant lesions [Slow ADC values:(1.05±0.31)×10-3 mm2/s;Standard ADC values:(1.13±0.39)×10-3 mm2/s] (t=3.90, 3.51;P<0.01), and the difference of Slow ADC value was largest between benign and malignant lesions. Slow ADC values of both benign and malignant lesions were significantly less than the Fast ADC values [benign:Slow ADC value=(1.83±0.86)×10-3 mm2/s, Fast ADC value=(16.95±8.63)×10-3 mm2/s; malignant: Slow ADC value=(1.05±0.31)×10-3 mm2/s, Fast ADC value=(15.12±9.90)×10-3 mm2/s] (t=-10.40,-6.29;P<0.01). Conclusion Double exponential decay model is capable of differentiating benign and malignant pelvic tumors, thus is of great significance for clinical preoperative diagnosis.
ABSTRACT
Objective To investigate the prevalence of unintended pregnancy (UP) and exploring the risk factors of UP for married women of child-bearing age from Qingshan district,Wuhan.Methods A cross-sectional study was adopted in this study.Cluster sampling method was used with 3256 women recruited,in 2010.Information on history and risks related to social-demographic factors of UP were collected,using a self-administered questionnaire.Results Of the 3256 participants,over half of them (53.8％) reorted ever having had the history of UP and 9.1％ reported UP in the past year.Rate of UP in the past year for different age cohorts (18-30,31-40,41-49 years) were 31.8％,10.5％ and 1.8％ respectively.The most frequently reported reason for UP across all the age cohorts was "Did not use any contraceptive methods",with proportions on the reason that reported by women at 18-30,31-40 and 41-49 year-olds,were 69.7％,51.1％ and 42.4％ respectively.The second frequently reported reasons for UP were "Failure of traditional contraception" for younger cohort ( 18-30 years:13.0％ ) and "IUD dropped or pregnancy with IUD" for older-age cohorts (23.4％ at 31-40 year-olds and 37.0％ at the 41-49 year-oplds).The most frequently cited reason for "Did not use any contraceptive methods" was "Believe we were lucky so far,not to get pregnant" (59.6％).The risk factors of UP were being at older age,experiencing sex debut at younger age and got married at younger age.Conclusion The prevalence of lifetime UP history was high among women at child-bearing age from Qingshan district,Wuhan.Reproductive health services and interventions should be taken according to the needs from different age cohorts of women.Younger cohort of women should receive more attention.
ABSTRACT
<p><b>OBJECTIVE</b>To study the effect of Shenfu Injection (SI) on the post-operative cognitive dysfunction in senile patients receiving the orthopedic surgeries after general anesthesia.</p><p><b>METHODS</b>100 patients, 60-89 years old, waiting for selective surgery at the orthopedics department, were randomly assigned to two groups, the SI group (50 cases) and the control group (50 cases), who met the standard of the American Society of Anesthesiologists (ASA) II-III. After surgical incision, patients in the SI group were transfused with SI 200 mL (50 mL SI was added in 200 mL normal saline), while those in the control group were transfused with 200 mL normal saline at the same time. The mean arterial pressure (MAP), heart rate (HR), and oxygen saturation (SpO2) were compared between the two groups before anesthesia, after intubation, 30 min and 60 min after anesthesia, 5 min and 30 min after extubation. The time for surgery, the time of intra-operative hypotension, the volume of hemorrhage, the time for post-operative consciousness recovery, the liver function, the kidney function, and the fasting blood glucose of patients before surgery, 3 days and 7 days after operation were compared. The cognitive functions of patients were tested before surgery, 3 days and 7 days after operation. The incidence of post-operative cognitive dysfunction of patients was compared between the two groups.</p><p><b>RESULTS</b>There was insignificant difference in MAP, HR, and SpO2 between the two groups at each time point (P > 0.05). There was insignificant difference in the pre-operative cognitive function score, the time for surgery, the time of intra-operative hypotension, the volume of hemorrhage, the liver function, the kidney function, and the fasting blood glucose between the two groups ( P > 0.05). The time for post-operative consciousness recovery was obviously shorter in the SI group than in the control group, showing significant difference (P < 0.05). The post-operative 3-day and 7-day cognitive function scores were obviously better in the SI group than in the control group, showing significant difference (P < 0.05). The incidence of post-operative cognitive dysfunction of the SI group [3 days: 12% (6 cases); 7 days: 8% (4 cases) ] was significantly lower than that of the control group [3 days: 20% (10 cases); 7 days: 14% (7 cases) ] ( P < 0.05).</p><p><b>CONCLUSION</b>SI could improve the post-operative cognitive function of senile patients receiving the orthopedic surgeries after general anesthesia, lower the incidence of post-operative cognitive dysfunction rate, and shorten the time for post-operative consciousness recovery.</p>

<p><b>AIM</b>To examine whether reproductive hormones play a role in the association between body mass index (BMI) and semen quality.</p><p><b>METHODS</b>Semen quality and testosterone (T), luteinizing hormone (LH), follicle-stimulating hormone (FSH) and estradiol (E(2)) were evaluated in 990 fertile males with age 38.9 +/- 9.7 (mean +/- SD) years recruited from the Chinese general population in 2001 and 2002.</p><p><b>RESULTS</b>Semen quality was reduced among underweight (BMI < 18.5) compared with normal (BMI 18.5-24.9) and overweight (BMI 25.0-29.9), but the associations were independent of reproductive hormones. After adjustment for the potential confounders, underweight men had reductions in sperm concentration (22.4 X 10(6)/mL), total sperm count (52.9 X 10(6)) and percentage of normal sperm forms (6.9%) compared with men with normal BMI. Being underweight may be a risk factor for low sperm concentration (OR: 4.68, 95% confidence intervals [CI]: 2.01-10.91). Otherwise, being overweight may be a protected factor for low sperm concentration (OR: 0.25; 95% CI: 0.08-0.83) and low total sperm count (OR: 0.37, 95% CI: 0.15-0.87).</p><p><b>CONCLUSION</b>Low BMI was associated with reduced semen quality. The associations between BMI and semen quality were found statistically significant even after adjustment for reproductive hormones. Reproductive hormones cannot explain the association between BMI and semen quality.</p>
