Objective To explore the short-term and long-term efficacy of laparoscopic versus open liver resection(LLR)in the treatment of hepatocellular carcinoma(HCC). Methods The perioperative and follow-up data ofLLR(n = 43)and OLR(n = 73)for the treatment of HCC at the same period were analyzed respectively. Results There were no significant differences in the age,gender,Child-Pugh classification,liver cirrhosis, AFP,and hepatic virus affection between the 2 groups. 1 case in the LLR group was converted for the open surgery and another one case in the OLR group died in the perioperative time. However ,compared with OLR group ,the intraoperative blood loss of LLR group(P < 0.05)was larger and the mean operative time(P < 0.05)was longer. The liver function indicators of the regular hepatectomy subgroup were recovered more quickly(P<0.05),but the indicators of remaining subgroups were not significantly different. The postoperative ambulation time (P < 0.05), the postoperative eating time(P < 0.05),the postoperative hospital stay(P < 0.05)were all shorter. The VAS score was lower(P<0.05). There was no difference in the incidence and distribution of complications and the inci-dence of severe complications between the two groups(all P>0.05). The first and third year disease-free survival rates were 82.2%,53.8%for LLR and 91.5%,75.9%for OLR,respectively(χ2=0.55,P=0.46). The first and third 5 year overall survival rates were 94.2%,79.3%for LLR and 94.9%,47.3%for OLR,respectively(χ2=1.06, P=0.30). Conclusion LLR for HCC treatment is a safe and effective way with the advantages of minimal opera-tive trauma,quick recovery and significant short-term efficacy.

Objective To study inflammatory cytokines changes in brain tissue of neonatal rats with periventricular leukomalacia (PVL).Method A total of 80 neonatal SD rats (P3) were randomly assigned into 2 equal groups,sham-operated group and PVL group.Rats in each group were further assigned into four subgroups (12,24,48,72 h),with 10 rats in each subgroup.The hypoxic-ischemic PVL modal were established following the procedure:first,isolation and ligation of left common carotid artery,and then exposed to 8％ O2 and 92％ N2 for 2.5 h.The sham-operated rats were processed with isolation of left common carotid artery only.Rats of the four subgroups were sacrificed at 12,24,48 h and 72 h respectively,then the brains were rapidly removed in corresponding time.Pathological changes of brain tissues were observed using HE stain.The mRNA expression levels of tumor necrosis factor α(TNF-α)and inter leukin-1β (IL-1β) were assessed using real-time quantitative PCR assays,the protein levels of TNF-α and IL-1β were detected using enzyme linked immunosorbent assay method.Result The brains tissues of rats in PVL group showed remarkably hyperemia and edema,with left ventricle enlargement.Periventricular white matter structure was disintegrated comparing with sham-operated group.The expression of TNF-α and IL-1 β mRNA in PVL group increased significantly,reaching peak by 24 h and then gradually decreased 72 h after the procedure.The mRNA levels of TNF-c and IL-1 β were significantly different between each two time points of 12,24 h and 48 h in PVL group (P ＜0.05).However,there was no differences between 72 h and 48 h within PVL and sham-operated group group(P ＞0.05).In PVL group,the protein expression trends of TNF-α and IL-1 β were similar to mRNA expression trends.Moreover,the protein levels were significantly different between each two time points of TNF-α and IL-1 β,respectively (P ＜ 0.01).The protein expression levels of TNF-α were different at each time point between PVL group and sham-operated group[(189.2 ± 20.4) pg/ml vs.(131.4 ±5.2) pg/ml at 12 h,(213.8 ± 16.7) pg/ml vs.(127.7 ±7.4) pg/ml at 24 h,(181.7 ± 15.0) pg/ml vs.(126.3 ± 6.0) pg/ml at 48 h,(159.6 ± 25.3) pg/ml vs.(131.4 ± 6.0) pg/ml at 72 h;P ＜0.01].The protein levels of IL-1β were different between the two groups only at 24 h and 48 h.[(121.8 ±30.0) pg/ml vs.(67.4 ± 13.7) pg/ml,(83.3 ± 15.7) pg/ml vs.(65.3 ± 14.9) pg/ml;P ＜0.05].In sham-operated group,no differences of TNF-α and IL-1 β protein levels were found between any different time points (P ＞ 0.05).Conclusion Inflammatory cytokines such as TNF-α and IL-1β are involved in ischemic-hypoxia induced PVL.Dynamic detection of inflammatory factors is expected to be an important method of early diagnosis,assessment of treatment efficacy and prognosis of PVL.

The indexes of respiration, circulation and rheoencephalography were measured before and after exercise.ResultsAfter exercise, blood-pumping function of heart improved obviously, stroke volume increased from (65.22±11.41)ml to (72.10± 10.78)ml, ejection fraction increased from (60.10±5.03)% to (68.78±6.25)%, while heart rate declined from (77.45±8.69) times/min to (7.89±8.21)times/min, capacity increased from (2.86±0.36)L to (3.34±0.53)L, and maximal voluntary ventilation for every minute increased from (96.14± 15.21)L to (114.02±16.01)L, significantly different compared with that before treatment ( P<0.01). The fluid time of rheoencephalography reduced from (0.171±0.058)s to (0.128±0.049)s ( P<0.01).ConclusionSport walking under proper intensity can improve the function of respiration and circulation system in old women, so it is a good way to keep health for the elders.

Objective To evaluate different post-processing imaging techniques of multi-slice helical CT cholangiography (MSCTC). Methods Fourty-seven patients were suspected of bile duct disease by ultrasound, with no abnormality by ordinary CT. These patients then received MSCTC examination. The original images were post-processed at workstation. The result of post-processed images was compared with that of the laparotomy and surgical bile duct endoscopy. Results Procedures were successful in 45 cases. Thirty-one cases were found with choledocholithiasis. The specificity and the sensitivity of CT virtual endoscopy (CTVE) for choledocholithiasis group were high. Cholangitis and cholangiocarcinoma were detected in 3 each cases.Three cases were finally found to have gallbladder polypus, in which only CTVE provided the diagnosis. The diagnosis of bile duct disease made by ultrasound were finally excluded by CTVE. Conclusions KG1 The available post-processing methods are CTVE and X-proj, MPR is applicable for observing bile duct wall, it is valuable in the diagnosis of all kinds of bile duct disease. CTVE is better than other methods at displaying intraluminal structure.
