Objective To study the preventive effect of volatile oil extracted from Foeniculum vulgare Mill. Seeds on the formation of postoperative intra-abdominal adhesion. Methods Thirty-eihgt SD rats were randomly divided into sham operation group (10), operation group (14) and volatile oil treated group (14):sham operation group was only operated by abdominal incision, the rest two groups were established animal model of abdominal adhesion by rubbing the procussus vermiformis of cecum with dry sterile gauze, clamping and scuffing abdominal wall. Half of rats were separately killed on day 7 and day 14 after surgery, respectively.The degree of adhesion was evaluated according to Phillips 5-scale grade and the feature of this model. Results The scores of intra-abdominal adhesion were significantly lower in the carbachol group than those in operation group both on 7 d and 14 d(P<0.01 ). Conclusion Volatile oil extracted from Foeniculum vulgare Mill. Seeds may take a significant role in the prevention of postoperative abdominal adhesion in rats.

Objective To perform anatomic study on percutaneous cannulated-screw fixation of symphysis pubis diastasis in human cadaveric pelvic specimens so as to provide a basis for clinical practice of the technique.Methods Fifteen adult pelvic cadaveric specimens were dissected to expose pubic symphysis,peripheral major vascular nerve,spermatic cord and round ligament of the uterus.Thickness of pubic symphysis and distance between the outer edge of pubic tubercle and spermatic funicle or round ligament of uterus were measured respectively.Distances were measured respectively from entry and exit points to the above-mentioned structures in the direction of guide pin.Entry depth and angles of guide pin with the coronal plane and cross section of the human body were measured.Surgery was simulated to prove the surgery effect through post-surgery filming and CT.Results Thickness of symphysis pubis was gradually reduced from up to down.Pubic tubercle part was the most thick and it could accommodate a 7.3 mm cannulated-screw.Entry and exit points of cannulated-screw were in certain distances with the important nervusvascularis and spematicfunicle (or round ligament of uterus) in the periphery,which were invulnerable to damages in the process of surgery.Proper lengths of cannulated screws were (73.6 ± 1.3) mm for males and (72.4 ± 1.7)mm for females (t =3.146,P < 0.05).Screw thread was completely embedded in pubic tubercle.Angles of guide pin with coronal plane and cross section of human body were (7.3 ± 1.1) °and (6.4 ± 1.0) ° for males (6.9 ± 1.5) ° and (6.1 ± 0.6) ° for females.Radiography and CT findings confirmed that all pin tracks were in the bone substances with angle and length of screws staying within the scope of experiment.Conclusion Percutaneous cannulated screw fixation is reliable and safe for symphysis pubis diastasis.

Objective To increase externally-assigned response, improve energy response of CR39 and develop positive fast/thermal neutron personal dosimeter applicable for occupational exposure in oil and gas field logging by using pre-recoil layer.Methods The externally-assigned response of CR39 detector was improved through increasing the track density by using the α particle induced by the reaction of 10B(n,α) 7Li with the BN as pre-recoil layer, and the increase was vilified by using both Monte-Carlo simulation and experiment exposed by standard neutron source.Results Fast/thermal neutron personal dosimeter's neutron flux sensitivity and neutron dose equivalent sensitivity were 3.46 × 10-4 track per 0.013 and 52.8 mSv.According to theoretical derivation and experiment of standard 241 Am-Be neutron source, detecting efficiency and energy response of CR39 were effectively improved, and quantitative measurement of dose contributed by thermal neutron was realized.Conclusions CR39 fast/thermal neutron personal dosimeter of high sensitivity is applicable to oil and gas field logging environment and of potential development.

Objective To investigate the association between nutrition and peripheral artery disease (PAD) in continuous ambulatory peritoneal dialysis (CAPD) patients.Methods One hundred and two stable CAPD patients from a single center were enrolled in this cross-sectional study.Automatic ankle-brachial index (ABI) measuring system was applied to examine ABI.Patients were divided into PAD group (ABI < 0.9) and non-PAD group (ABI≥0.9).Clinical data were collected.Biochemical parameters were detected.Nutritional status was evaluated by serum albumin,handgrip strength (HGS) and subjective global assessment (SGA).Logistic regression analysis was performed to estimate the association of PAD with each nutritional marker as well as other potential risk factors.Results The incidence of PAD was 23.53% (24/102).ABI was significantly lower in patients with malnutrition as compared to those without malnutrition [(0.72 ± 0.21) vs (1.04 ± 0.14),P<0.01].Compared with non-PAD patients,serum albumin (P < 0.01),HGS (P < 0.01),diastolic blood pressure (P < 0.05),serum creatine (P < 0.05)、blood urine nitrogen (P < 0.01) were significantly decreased,but age (P < 0.01),the incidence of malnutrition [SGA,P < 0.01],diabetic status (P < 0.01),cardiovascular disease history (P < 0.01) were significantly increased in PAD patients.Logistic regression analysis showed that serum albumin (OR=0.762,95% CI:0.611-0.948,P=0.015),HGS (OR=0.988,95% CI:0.979-0.997,P=0.013) were independent protective factors for PAD,malnutrition [(SGA),OR=21.101,95% CI:5.008-88.901,P<0.01] was independent risk factor for PAD in CAPD patients.Conclusions The PAD incidence of CAPD patients in our center is 23.53%.Nutrition is independent factor associated with PAD in CAPD patients.

Objective:
To provide the evidence for tuberculosis pvevalence for high school freshmen by analyzing data of entrance physical exarnination of Chongqing in 2018.
Methods:
The TB information management system of schools in Chongqing was used to collect the data of TB physical examination for high school freshmen in 2018. Excel 2007 was used to establish database, SPSS 25.0 software was used for statistical analysis, including descriptive analysis, chi square test.
Results:
In 2018, a total of 118 370 freshmen from 146 general education high schools and a total of 30 842 freshmen from 30 secondary vocational schools had TB screening during physical examination for freshmen. The proportion of school and freshmen participating in the TB examination was 40.09% and 44.28% respectively. The rates of school (57.03%) and freshmen (58.81%) participating in the examination of tuberculosis in senior high school students of general education were higher than those in secondary vocational education schools(16.39%, 22.73%), the difference was statistically significant(χ2=73.38, 42 744.64, P<0.01). 84 cases of active pulmonary tuberculosis (APTB) were detected in the physical examination of high school freshmen, mainly smear negative patients (92.86%),and there was no significant difference in the prevalence of tuberculosis among the freshmen with different education, school and screening methods(P>0.05). The detection rates of TB among freshmen in general education and vocational education were 49.00/100 000 and 54.62/100 000 respectively. The detection rates of tuberculosis among freshmen in public schools and private schools were 50.29/100 000 and 124.88/100 000 respectively(χ2=5.42, 10.92, P<0.05). The detection rate of direct chest X-ray examination was 62.90/100 000. The first screening method was PPD test and the detection rate of chest X-ray examination was 84.30/100 000 for those with strong positive PPD test, the differences was no significant(χ2=0.29, P>0.05).
Conclusion
The tuberculosis screening program for high school freshmen is of great significance to the prevention and control of tuberculosis. Effective screening methods should be adopted and strengthened in secondary vocational schools.
