A medical studies have indicated that there would be a defense response from human body after TBI,which mainly comes with inflammatory reaction. Human body's resistance seems likely to be enhanced,during this process, by inflammatory cytokines leading to rehabilitation of the cellular organization.However,a strong Inflammation from the whole human body may be caused due to the excessive activation,which, instead, worsens secondary brain injury. This article discusses the relationship between cytokines and traumatic brain injury.

Objective To evaluate the prognostic value of lateral lymphadenectomy for advanced lower rectal cancer. Methods A total of 96 consecutive patients who underwent total mesorectal excision and lateral lymphadenectomy for advanced lower rectal cancer were retrospectively evaluated by using therapeutic index. A product of the frequency of lymph node metastasis and the cancer-related 5-year survival rate. Results The incidences of lymph node metastasis in mesorectal area, superior rectal artery area, inferior mesenteric artery area and lateral area was 21%,13%.10%and 15%respectively.The 5-year survival rate of patients with metastasis to the mesorectal area, superior rectal artery area, inferior mesenteric artery area and lateral area was 35%,25%,20%and 36%respectively.The therapeutic indexes for total mesorectal excision and lateral lymphadenectomy were 7.4 and 5.4,which were much higher than that of lymphadenectomy of the superior rectal artery area(3.3)and inferior mesenteric artery area(2.0).Local recurrence occurred in 19%(18 out of 96 cases)patients with advanced lower rectal cancer. Local recurrence rate of patients with positive lateral lymph node metastasis was 64%(9 of 14 cases),whereas it was 11%(9 of 82 cases)in those without lateral lymph node metastasis. The difference between these two groups was statistically significant(x2=22.308,P=0.000).Kaplan-Meier survival analysis showed significant improvements in median survival(80.9±2.1)m,95%CI:76.7～85.1 m vs(38±6.7)m,(95%CI:24.8～51.2 m)for patients with negative lateral lymph node metastasis over patients with lateral lymph node metastasis(log-rank,P=0.000). Conclusion The current results indicate that lateral pelvic lymphadenectomy could significantly reduce loeal recurrence and effectively improve the survival of patients with advanced lower rectal cancer. Except for total mesorectal excision, lateral pelvic lymphadenectomy should be followed in the surgery of pailents with advanced low rectal cancer.

Objective To analyze the main clinical features and impact factors of simple renal cyst (SRC), and to provide evidence for the future prevation and cure of simple renal cysts.Methods In this crosssectional study,a total number of 91 433 participants(aged 18-98 years old) were included who underwent health examinations during 2012-2014.The main life styles and clinical features of each participants were recored,and blood biochemistry test, urinanalysis and renal ultrasonography were performed.Results The prevalence of SRC was 2.70％ (2 465 subjects were diagnosed by ultrasonography).It was higher in men than women(2.95％ vs.1.68％, P =0.00), which was increased with the increasing of age (respectively 0.37％, 0.57％, 1.30％ ,2.69％ ,4.46％ and 6.91％ in the group of ≤29year,30-39 year,40-49 year,50-59 year,60 -69 year and ≥70 year,P＜0.01).The maximum diameter of simple renal cysts were (2.6±1.7) cm.Age,rate of men, body mass index, glucose, total cholesterol, creatinine, urea nitrogen, and urinary protein positive rate, kidney stone prevalence were higher in SRC group(respectively (61.11±11.24)year vs.(51.37±13.72) year, 87.59％ vs.79.88％, (25.27 ± 3.19) kg/m2 vs.(24.97 ± 3.35) kg/m2, (6.09 ± 2.08) mmol/L vs.(5.70 ± 1.85) mmol/L, (5.11 ± 1.54) mmol/L vs.(5.02 ± 1.37) mmol/L, (90.71 ± 34.84) μmol/L vs.(80.72 ±28.04) μmol/L, (6.03±3.60) mmol/L vs.(5.55±5.15) mmol/L,7.46％ vs.4.25％ ,7.06％ vs.1.28％ ,P ＜0.01) ,but glomerular filtration rate, triglycerides, rate of like salty, drink, smoke was lower than the group withoutSRC((79.01±19.89) ml/(min· 1.73 m2) vs.91.74±21.8 ml/(min · 1.73 m2),(1.57±1.48) mmol/L vs.(1.69± 1.82) mmol/L, 4.38％ vs.7.94％, 22.68％ vs.30.75％, 24.91％ vs.30.97％;P＜ 0.01).But,there was no difference between these two groups in serum uric acid ((309.16± 85.79) μmol/L vs.(312.38±91.22) μmol/L,P＞0.05).SRC as a dependent variable of multivariate log regression analysis.The result showed the OR of age, gender, fasting blood glucose, urea nitrogen, glomerular filtration rate, positive urine protein,kidney stone were respectively 1.040, 1.862, 1.035, 1.005,0.982, 1.254, 4.526, 95％ CI =1.037 -1.045,1.643-2.110,1.017-1.053,1.000-1.010, 0.980-0.984, 1.068-1.473,3.812-5.374;P ＜0.01).While the OR of multiple SRC was 0.43,95％ CI: 0.210-0.867 (P＜0.05) , when kidney stone as a dependent variable.Conclusion Old-age males are high risk population of catching SRC.Kidney stone and positive urine protein are important risk factors of SRC.Meanwhile kidney stone more easily induce single and small SRC.SRC is a key risk factor to induce renal function decrease.Therefore, GFR is a sensitive index of renal disfunction that induced by SRC.

Objective To analyze the related factors of influencing deep vein indwelling catheter dysfunction in hemodialysis patients.Methods A total of 37 cases with deep vein indwelling catheter in hemodialysis patients were selected.They were divided into patent group and blocked group according to the appearance of catheter dysfunction (hemodialysis blood flow less than three times 180 ml/min,adjustment of body position,inversion of tube connection during hemodialysis,requirement of thrombolytic therapy and so on) in 5 months.The common data and biochemical indicator were compared between two groups.Results Patent group had 28 cases,and blocked group had 9 cases.There was no significant difference in age,diabetes mellitus ratio,platelet,low density lipoprotein cholesterol and albumin between two groups (P ＞0.05).Hemoglobin in patent group was lower than that in blocked group [(90.1 ± 13.8) g/L vs.(108.3 ± 11.6) g/L],and there was significant difference(P＜ 0.05).Conclusion Hemoglobin is the correlated factor that effects deep vein indwelling catheter dysfunction after hemodialysis.

Objective To discuss the clinical characteristics,treatment and prognostic factors of brain metastasis from gynecological cancers.Methods Clinical records of 25 brain metastasis patients from gynecological cancers admitted from January 1999 to January 2009 were reviewed retrospectively.The curative effects of different treatments were compared.The prognostic factors were determined using the Cox regression model.Results There were 14 cases ovarian malignant tumor,6 cases cervical carcinoma and 5 cases uterine malignant tumor.Seven cases (28％,7/25 ) had solitary metastatic lesion in the brain.Extracranial metastases were detected in 18 cases (72％,18/25 ).Five patients only received one kind of treatment,and the mean survival time was 4.0 months (0.5 to 9.5 months).Sixteen patients received combined treatment,3 of them received combined treatment including surgery,and the mean survival time was 8.4 months (4.1 to 13.4 months) ; 13 of them received chemotherapy and radiotherapy,and the mean survival time was 14.2 months (4.3 to 58.1 months).Four patients received only palliative supportive care,and the survival time was only 0.1 to 1.0 month.The Cox regression model showed that Karnofsky performance status scale,with or without extracranial metastases and the treatment method were the independent prognostic factors of brain metastasis from gynecological cancers ( P ＜ 0.05 ).Conclusion The incidence of brain metastasis from gynecological cancers is low and the prognosis is very poor.Combined treatments may get better effects.

Objective: To objectively evaluate the short-term and long-term efficacies of arthrolysis under brachial plexus anesthesia in treating adhesive capsulitis of the shoulder (ACS). Methods: One hundred patients diagnosed with ACS were divided into two groups using the random number method. The two groups both received same active rehabilitation exercises. Besides, 55 cases in the treatment group were given one session of arthrolysis under brachial plexus anesthesia, and 45 cases in the control group were given tuina treatment. Changes in the visual analog scale (VAS) score, Melle score and pressure pain index were observed 1 month and 3 months after treatment. The therapeutic efficacies were also compared. Results: The total effective rate was 96.4％ at the 1-month follow-up and 96.4％ at the 3-month follow-up in the treatment group. The total effective rate was 33.3％ at the 1-month follow-up and 28.9％ at the 3-month follow-up in the control group. There were significant differences between the two groups comparing the total effective rate at the two time points (both P<0.05). The scores of VAS, Melle and pressure pain were significantly different at the 1-month and 3-month follow-ups from those before treatment in the treatment group (all P<0.05); the three scores did not show significant differences at the 1-month and 3-month follow-ups compared with those before treatment in the control group (all P>0.05). Conclusion: Based on the active rehabilitation exercises, one session of arthrolysis under brachial plexus anesthesia can release the adhesion and restore the range of motion and function of shoulder joint in ACS patients. It is superior to rehabilitation exercises plus tuina treatment comparing both short-term and long-term efficacies.

Cardiac toxicity is found in frequently used chemotherapeutic agents.There are many factors related to the cardiac toxicity caused by chemotherapeutic agents.The common cardiovascular complications include heart failure,ischemia,hypertension,hypotension,edema,QT prolongation,pleural effusion,pericardial effusion,bradyarrhythmia and thromboembolism.It is necessary to monitor the left ventricular function before and after chemotherapy and take effective measures to protect myocardium.

AlM: To observe the effect of dacryocystorhinostomy for the treatment of chronic dacryocystitis using nasal endoscope and discuss the operation technique. METHODS: A retrospective clinical analysis was performed on the clinical data followed up for 6 ~12mo from 140 patients (169 eyes) with dacryocystorhinostomy for the treatment of chronic dacryocystitis using nasal endoscope. The effect of the treatment was evaluated and the operation technique for the treatment of chronic dacryocystitis using nasal endoscope was discussed.RESULTS: ln all of cases 155 eyes ( 91. 7%) were recovery, 3 eyes ( 1. 8%) were improved, and 11 eyes (6. 5%) were failure. The total efficiency was 93. 5%, there was no significant difference compared with traditional dacryocystorhinostomy group (χ2=3. 743, P>0. 05). CONCLUSlON: Dacryocystorhinostomy using nasal endoscope for treatment of chronic dacryocystitis has a good curative effect. Techniques including lacrimal sac location and size, colostomy position and size, treatment of colostomy mucosal flap and nasal disease, postoperative follow - up and physical condition of patients are likely to affect the operation curative effect.

AIM: To investigate the influence of Ginkgo biloba extract (EGb761) on c-jun expressions and motoneurons survival following root avulsion. METHODS: One hundred and eighty adult Sprague-Dawley female rats were randomly divided into control and EGb761 groups. Immediately after avulsion of C5-T1 nerve roots, the rats were injected ip with either 1 mL of EGb761 25 mg?kg~(-1)?d~(-1) or the same volume of normal saline, and the treatment repeated everyday. At 4 h to 6 weeks following avulsion, the C7 spinal segments of all rats were collected and prepared for c-jun immunocytochemistry and neutral red stain. The numbers of (c-jun) positive and survival motoneurons were counted and compared between two groups at each time point. RESULTS: In control rats following avulsion, c-jun positive motoneurons appeared at 4 h, reached its maximum at 1 d and declined to 2 weeks. Avulsion-induced motoneurons death started at 2 weeks, climbed to its maximum at 4 weeks-6 weeks. In EGb761 treated rats, both numbers of c-jun positive and survival motoneurons were more than that in control group at each time point. CONCLUSION: EGb761 attenuates avulsion-induced motoneurons death, and this effect may be related to up-regulation of c-jun gene in avulsed motoneurons. [
