Objective To study effect of parecoxib on sufentanil dosage and its analgesic effect in patients with laparoscopic radical resection of rectal carcinoma under combined anesthesia.Methods 120 cases patients diagnosed with rectal cancer and prepared to laparoscopic radical resection of rectal cancer were selected in Kailuan General Hospital, and randomly divided into experimental group and control group, 60 cases in each group, experimental group induced anesthesia with 40mg parecoxib sodium intravenous injection, while the control group were treated with normal saline, the postoperative dosage of sufentanil, analgesia pump using frequency and other indicators were detected at 6,12,24 and 48 h, and analgesic effect were observed.Results Compared with control group, in experimental group, postoperative dosage of sufentanil was less ( P <0.05 ) , analgesia pump pressing times and effective pressing numbers were fewer (P<0.05), VAS pain score was lower (P<0.05) and Ramsay score was lower (P<0.05) at each time point.Conclusion Parecoxib could reduce the dosage of sufentanil after laparoscopic radical resection of rectal cancer, and enhance the analgesic effect.

Objective: We observed the influence of recombinant human growth hormone(rhGH) on protein metabolism in hepatocirrhotic rats and investigated mechanisms. Methods: Ninety rats were randomized into three groups(n=30 for each group): group A(normal rats), B(cirrhotic rats) and C(cirrhotic rats receiving rhGH). Rats in group C were subcutaneously given rhGH with a dosage of 1 U/(kg?d) for up to 1 week. The plasma concentrations of albumin(ALB), prealbumin(PA), transferrin(TF) and insulin-like growth factor-1(IGF-1) were detected on experimental day 14. And liver biopsy was taken to examine the expression level of albumin mRNA with TR-PCR. Results: The albumin, prealbumin, transferrin and IGF-1 levels in groups A and C were significantly higher than those in group B. The expression level of albumin mRNA in grup C was significantly higher than that in group B. Conclusions: The rhGH can improve the level of IGF-1 in plasma and improve the expression of albumin mRNA. Moreover, it may significantly improve the synthesis of protein and attenuate hypoproteinemia in cirrhotic rats.

OBJECTIVETo explore the effect of a self-made guiding needle of steel wire in guiding the wire through the tibial tunnel for the treatment of avulsion fractures of tibial posterior cruciate ligament with open reduction and wire fixation.

METHODSFrom February 2011 to June 2014, a total of 22 patients with avulsion fractures of tibial posterior cruciate ligament underwent surgical treatments were analyzed, including 14 males and 8 females with an average age of 35.6 years old (ranged, 17 to 63 years old). According to Meyers classification, 9 patients were classified as type II, 13 patients were classified as type III. All the patients underwent open reduction and wire fixation with medial knee "L" shape approach. A wire guiding needle was used to guide the wire through the tibial tunnel during operation.

RESULTSWith the assistance of wire guidance needles, wires passed through the tibial tunnel rapidly during the operation in all the 22 patients. All the patients were followed up, X-ray imagings 6 months after operation showed the fractures healed well. The average follow-up time in all patients was 6 months (ranged, 6 to 12 months). The averaged Lysholm knee score in 22 knee was 92.7 +/- 3.4. All patients' posterior drawer test were negative.

CONCLUSIONSelf-made wire guiding needle can simplify the operation procedures in which the wires pass through the tibial tunnel, shorten the operation time, reduce the surgical trauma and complications, and be worthy of clinical application.

The cardiovascular circulation feedback control treatment instrument (CFCTI) is an automatic feedback control treatment system, which has the function of monitoring, alarming, trouble self-diagnosis and testing on the line in the closed loop. The instrument is designed based on the successful clinical experiences and the data are inputted into the computer in real-time through a pressure sensor and A/D card. User interface window is set up for the doctor's choosing different medicine. The orders are outputted to control the dose of medicine through the transfusion system. The response to medicine is updated continually. CFCTI can avoid the man-made errors and the long interval of sampling. Its reliability and accuracy in rescuing the critical patients are much higher than the traditional methods.

Objective To assess the occupational health risk of noise in a plastic products enterprise and determine the key risk Methods - points. The workplace of a plastic products enterprise and its 388 noise exposed workers were selected as the ， research subjects using a convenient sampling method. The noise intensity in the workplace of the enterprise was measured and - GBZ/T 229.4-2012 the individual noise exposure level and pure tone hearing test were carried out in the noise exposed workers. Classification of Occupational Hazards at Workplaces--Part 4： Occupational Exposure to Noise（ GBZ/T hereinafter referred to as 229.4-2012） - was used to evaluate the hazardous degree of noise in different posts. The risk of high frequency hearing loss （ ） - （ ） - ， ， HFHL and occupational noise induced deafness ONID in noise exposed workers in different posts at 45.0 50.0 55.0 and WS/T 754-2016 Guideline for Risk Management of Occupational Noise Hazard（ 60.0 years of age were predicted using hereinafter WS/T 754-2016）Results referred to as . The noise in the workplace of this plastic product enterprise was found to exceed the - occupational exposure limits with the rate of 46.6%. The maximum level of normalization of equivalent continuous A weighted - （ ） sound pressure level to a nominal 40 h working week of exposure to noise in workers of six posts was 84.0 93.0 dB A . - ， ， ， According to GBZ/T 229.4 2012 the noise hazards of the posts including extrusion premixing unloading and utility - ， maintenance were mild or moderate except for the film and packaging posts. According to WS/T 754 2016 the risks of HFHL in ， ， the film and packaging operators at age ≥50.0 years old were at acceptable risk and the risks of HFHL in operators of extrusion ， ， premixing unloading and utility maintenance at age ≥45.0 years old were at moderate risk or high risk.

OBJECTIVE To study the effects of Qishen capsule against focal cerebral ischemia reperfusion injury in rats.METHODS The rat model of focal cerebral ischemia-reperfusion was established with the middle cerebral artery occlusion (MCAO)by reversible inserting a nylon thread method. Rats were killed after ischemia 1 hour and reperfusion 2 hours. Brain were fetched out and measured the contents of H2 O, [ Ca2 + ] i, NO, neurological function evaluation and infarct volume and the activities of NOS,Ca2+ -ATPase, Na+ , K+- ATPase. The sections were stained with hemotoxylin-eosin(HE) or TTC, histological changes of brain were observed. RESULTS Compared with sham operation group, H2 0 and [ Ca2 + ] i, NO contents were lower significantly and the activity Qishen capsule has protective effects on cerebral ischemia-reperfusion lesion.

Objective: To analyze associations of MRI-lesions and clinical features with disability in patients with multiple sclerosis (MS) in Shanghai, China. Methods: We studied patients with MS, identified from a survey in Shanghai, whose sites of lesions in the CNS was based on the MRI examinations. Associations between MRI-lesions, various clinical variables and the severity of disability were analyzed with univariate and multivariate logistic regression analysis. Results: There were 210 patients in this study. The disability of the patients with lesions confined to the spinal cord was significantly more severe than those with lesions in the brain (p < 0.008). Current age (OR: 1.041, 95% CI: 1.007~1.077), MS duration (OR: 1.082, 95% CI: 1.011~1.159) and MRI-lesions in the spinal cord (OR: 2.441, 95% CI: 1.039~5.737) were significantly associated with severity of disability on multivariate logistic regression analysis. Conclusion: MRI-lesions in the spinal cord, older age, a longer MS duration were significantly associated with a more severe disability in this MS study in Shanghai China.
