Liver fibrosis can be caused by chronic liver injury arising from various etiological factors and it is a reversible process. The activation of the hepatic stellate cell( HSC) is the central event in liver fibrosis,since we know that cytokines secreted from Kupffer cell participate in HSC proliferation,apoptosis and ECM metabolism. In this paper we focus on the relation-ship between HSCs,Kupffer cell,cytokines and the course of hepatic fibrosis. Elucidating this relationship will benefit research on the role of Kupffer and HSCs in hepatic fibrosis.

Objective To investigate the effects of laparoscopic and open resection with pelvic autonomic nerve preservation (PANP) on sexual function of male patients with lower rectal cancer. Methods Total 177 male patients with lower rectal cancer received surgery from September 2008 to December 2013 were enrolled into two groups: the laparoscopic PANP group (n = 105) and the open PANP group (n = 72). The classifications of erectile and ejaculatory functions were used to evaluate the sexual functions of patients at 6 months and 12 months post-operation, respectively. The effect of different operation on the sexual function of the male patients was compared between the two groups. Results The incidence rates of erectile dysfunction at 6 months and 12 months post-operation in the laparoscopic group were lower than those in the laparotomy group (P < 0.05). The incidence rates of ejaculatory dysfunction at 6 months and 12 months post-operation in the laparoscopic group were also lower than those in the laparotomy group (P < 0.05). Conclusion The laparoscopic resection with PANP in patients with lower rectal cancer can not only clearly reveal pelvic autonomic nerve and effectively protect them, but also reduce the incidence of postoperative sexual dysfunction.

Objective To promote the understanding and diagnostic acuity of Hirayama disease by studying the features of electromyogram (EMG) and nerve conduction. Methods EMG was performed in 33 patients with Hirayama disease. Surface electrode was applied to examine the median nerve, cubital nerve, musculospiral nerve and part of the popliteal nerve, and the motor nerve conduction velocity (MCV), distal motor latency (DML) and the amplitude of compound muscle action potential (CMAP) were recorded. The sensory nerve conduction velocity (SCV) was also examined in the median nerve, cubital nerve and part of the sural nerve. Results The neurogenic abnormalities were detected in extremity muscles, with exception of brachioradial muscle, of upper limbs. In all the 33 patients damage was found on the illness-side and 97.0% on the contralateral side. One patient was found to have neurogenic abnormality of brachioradial muscle and 4 of proximal muscles, including 1 in whom muscle of lower limbs was involved. EMG abnormality rate of distal muscles (89.9%) was significantly higher than that of the proximal muscles of upper limbs (6.7%) and also muscles of lower limbs (1.7%). EMG also showed that there was delayed distal motor latency (DML) and decreased wave amplitude of compound muscle action potential (CMAP) in the nerves of upper limbs. statistically significant difference was found between the CMAP amplitude of affected limb (2.52?1.83mV) and the contralateral upper limb (9.82?3.57mV) by the detection of ulnar nerve conduction, while no difference and no nerve block were found between the DML of affected limb (4.25?1.33ms) and the contralateral upper limb (3.28?0.36ms). Conclusions Electrophysiological changes may be detected in some patients with subclinical Hirayama disease, of which the electrophysiological test is valuable in establishing early diagnosis.

Objective To study the application of doses of remifentail intravenous anesthesia in vocal nodule extirpation.Methods Sixty ASAⅠ～Ⅱpatients with vocal nodule were selected and randomly divided into three groups. Group F were given anesthetic induction with fentanil and maintenance with isoflurane; Group L were given anesthetic induction and maintenance with remifentail at the dose of 0.5?g/(kg?min); Group H were given anesthetic induction and maintenance with remifentail at the dose of 1?g/(kg?min).The anesthetic induction time,blood flow dynamics during maintenance phase,recovery time and quality were recorded. Results (1)Anesthesia produce less circulatory fluctuation in group H than in group F and L.(2) Group L and H were faster than group F on recovery profile including the time of response to verbal commands,autonomous breathing,tracheal extubation and discharging from operating room. The OAA/S score was higher in group L and H than in group F 5 min after intubation. There were no significant differences between group L and H. Conclusions Remifentanil intravenous anesthesia can achieve better recovery profile from anesthesia than fentanyl in vocal nodule extirpation. 1?g/(kg?min) remifentanil can inhibit the stress responses to tracheal intubation and laryngoscope inserted effectively with a stable circulatory function.

Objective To investigate the influences of large-scale military exercise on immune and endocrine secretory function of soldiers.Methods The psychological stress self-evaluation test(PSET)was applied on 126 officers and soldiers before and after the military exercise.Radioimmunoassay(RIA)technique was employed to determine the contents of serum interlukine-2(IL-2),interlukine-6(IL-6),interlukine-8(IL-8),tumor necrosis factor(TNF),cortisol(Cor)and aldosterone(Ald)in 126 subjects.All data were processed by correlation analysis.Results Compared with that of before exercise,the contents of serum IL-2 declined significantly(P

Objective To investigate the correlation between psychological stress status and the personality of the soldiers who took part in a large-scale military exercise. Methods The psychological stress self-evaluation test (PSET), SCL-90 game and Eysenck personality questionnaire (EPQ) were conducted in 126 servicemen before and after a field military exercise. Correlation between psychological stress status and their personality profile was studied versus the SCL-90 after military exercise. Results 126 servicemen who had taken part in the military exercise were tested with PSET. The number of persons whose PSET data T≥70 increased from 9 before the exercise to 35 after the exercise (P
