Objective To study the value of transcatheter arterial chemoembolization (TACE)in combination with portal vein chemotherapy (PVC) after resection of hepatocellular carcinoma to prolong survival. Methods From January 2000 to July 2007, 168 patients with hepatocellular carcinoma (HCC) underwent tumor resection in our hospital. After operation, TACE in combination with PVC was performed in 48 patients (combined group), TACE alone in 26 (TACE group), PVC alone in 50 (PVC group) and none of the above in 44 (control group). All the patients were followed up for 17-96 months. The 1-, 3-and 5-year survival rates were compared among the 4 groups. Results Accumulative 1-, 3-and 5-year survival rates were higher in the combined and TACE groups than in PVC and control groups. Conclusion After resection of HCC, combined use of TACE and PVC is the same as TACE in prolonging patient survival. However, it is better than PVC alone and non-surgical procedure.

OBJECTIVETo observe the therapeutic effect of Qilin Pills combined with clomiphene on idiopathic oligoasthenospermia.

METHODSWe randomly assigned 300 patients with idiopathic oligoasthenospermia to a trial (n = 156) and a control group (n = 144) to be treated with Qilin Pills (6 g, tid) combined with clomiphene (50 mg, qd) and clomiphene alone (50 mg, qd), respectively, both for a course of 12 weeks. Before and after 4, 8, and 12 weeks of medication, we determined sperm concentration, the percentages of grade a and grade a + b sperm, sperm motility, and the levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone (T), followed by evaluation of the clinical efficacy of Qilin Pills with the pregnancy rate in the patients' spouses as the secondaty therapeutic indexes.

RESULTSCompared with the baseline, both groups of patients showed remarkably improved semen parameters and hormone levels after treatment (all P < 0.01). After 4, 8, and 12 weeks of medication, statistically significant differences were observed between the trial and control groups in sperm concentration ([17.06 ± 2.24] vs [15.07 ± 2.48], [22.10 ± 2.65] vs [18.11 ± 2.97], and [28.13 ± 3.59] vs [21.21 ± 3.60] x 10(6)/mL, P < 0.01), the percentage of grade a sperm ([15.03 ± 2.39] vs [13.08 ± 2.51], [21.08 ± 3.16] vs [16.04 ± 3.05], and [28.08 ± 4.70] vs [20.14 ± 4.74]%, P < 0.01), the percentage of grade a + b sperm ([30.10 ± 5.07] vs [26.21 ± 3.96], [38.08 ± 5.64] vs [30.07 ± 4.80], and [48.04 ± 6.49] vs [35.28 ± 4.77]%, P < 0.01), sperm motility ([42.04 ± 4.86] vs [40.29 ± 4.19], [52.05 ± 5.58] vs [48.03 ± 4.40], and [65.03 ± 5.13] vs [56.67 ± 4.99]%), the FSH level ([7.75 ± 1.38] vs [7.20 ± 1.17], [10.83 ± 1.23] vs [9.10 ± 1.32], and [14.22 ± 0.84] vs [12.06 ± 1.45] IU/L, P < 0.01), the LH level ([10.05 ± 1.68] vs [9.18 ± 1.54], [13.96 ± 1.68] vs [11.99 ± 1.71], and [19.01 ± 2.42] vs [15.86 ± 2.08] IU/L, P < 0.01) and the T level ([19.19 ± 192] vs [18.34 ± 1.79] [21.06 ± 1.63] vs [20.06 ± 1.56], and [24.63 ± 1.06] vs [22.03 ± 1.49] nmol/L, P < 0.01). The pregnancy rate in the patients' spouses was significantly higher in the trial than in the control group at 4, 8, and 12 weeks (1.92 vs 0.69, 4.81 vs 3.47, and 11.54 vs 8.33%, P < 0.01). There were no statistically significant differences in drug tolerance between the two groups (P > 0.05). No obvious adverse reactions were observed.

CONCLUSIONQilin Pills combined with clomiphene can evidently improve the seminal quality and hormone level of oligoasthenospermia patients with no obvious adverse events. However, its long-term efficacy and tolerance deserve further clinical investigation.

OBJECTIVETo evaluate the efficacy and safety of adjuvant interferon (IFN) therapy for viral hepatitis related hepatocellular carcinoma(HCC) after the treatment of resection, ablation or TACE.

METHODSPUBMED, EMBASE, Cochrane Library, CNKI, CBM, Wan fang Data were searched, plus some manual search and searching on the internet for grey literature. The studies that according to the standards were included, then Meta-analysis were done.

RESULTSEight studies (n=857, 442 treated with IFN) were eligible for this study, pooled data showed benefit of IFN for the prevention of HCC recurrence, 1-year [RR=0.71, 95% CI (0.51, 0.99)], 3-year [RR=0.86, 95% CI (0.76-0.98)], 4-year [RR=0.79, 95% CI (0.68-0.91)]. IFN showed benefit for improving 1-year and 2-year survival, 1-year [RR=1.09, 95% CI (1.01-1.18)], 2-year [RR=1.25, 95% CI (1.04-1.50)]. The difference on 2-year, 5-year recurrence rate are without statistical significance, the same to 3-year, 4-year, 5-year survival rate.

CONCLUSIONIFN therapy after the treatment of resection, ablation or TACE can probably reduce HCC recurrence rate and improve survival with acceptable toxicities.

OBJECTIVETo investigate the clinical and histological features of the complications after hydrophilic polyacrylamide gel injection.

METHODSFifty-two patients were included in this study, who had undergone hydrophilic polyacrylamide gel injection in other units from 1998 to 2003 and later came to our department for removal of the injected gel. The tissue samples taken from each cyst were sectioned and stained with hematoxylin and eosin. The sections were investigated and analyzed under light microcopy. The tissue sections of 12 patients who had ever received liquid silicone injection from 1988 to 1994 were used as the control group. The difference in histological features was assessed.

RESULTSThe inflammatory reaction of the hydrophilic polyacrylamide gel was characterized by an increased number of foreign-body giant cells. The mild lymphocyte infiltration was shown in the slides of hydrophilic polyacrylamide gel. On the contrary, there were much more clusters or lymphocyte infiltration in the slides of liquid silicone. The differences between the hydrophilic polyacrylamide gel and liquid silicone were significant in terms of thickness of the fibrous capsule.

CONCLUSIONSThe security of hydrophilic polyacrylamide gel injection for soft tissue augmentation is in doubt.

OBJECTIVETo evaluate the clinical efficacy of Ganxian recipe (GXR) and lamivudine (LVD) in a two-year treatment of chronic hepatitis B (CHB).

METHODSOne hundred and twenty patients with CHB were randomly divided into the combinedly treated group (combined group) of 40 CHB patients who were treated with GXR combined with LVD. Another 40 CHB patients were treated with LVD alone (WM group), and still another 40 CHB patients were treated with GXR alone (TCM group). All these cases were randomly controlled and observed for two years.

RESULTSComprehensive efficacy: Total effective rate of the combined group (complete response and partial response) was 92.5%, while that of the WM group was 67.5% and TCM group 57.5%, respectively, with the difference between them was significant (P < 0.01); after treatment, the hepatic functions (AST, ALT, SB) of the three groups were all reduced, and the reduction in the combined group was particularly significant in comparison with the WM group or TCM group, P < 0.05 or P < 0.01 respectively, suggesting that the effect in the combined group was better than that in the other two groups; the rate of tyrosine-methionine-aspartate-aspartate (YMDD) virus mutation: it was 7.5% in the combined group, 40.0% in the WM group, and 5.0% in the TCM group; liver fibrosis improvement parameter: after treatment, the results in the combined group got better than those in the other two groups.

CONCLUSIONGXR could inhibit the appearance of YMDD after long-term application of LVD, and combined use has marked synergism.

Objective To investigate the effects of functional electrical stimulation (FES) on endogenous proliferation of the neural stem cells within the brain and the behaviors in rats with acute cerebral infarction and explore the FES therapeutic mechanism on improving the neural function after the cerebral infarction. Methods Fifty-four SD adult male rats were randomly allocated into FES treatment group, placebo stimulation group and sham-operated group (n=18). Focal cerebral infarction models were induced by the performent of middle cerebral artery occlusion (MCAO) in rats; the FES treatment group began receiving the FES (10 min/d, once dairy) and the placebo stimulation group did not give any special treatment since the 3rd day of the successful model inducement. The expression of nestin positive cells in the hippocampus subgranular zone and subventricular zone was examined by immunohistochemistry staining and the expression of nestin protein at ischemia side was detected by Western blot analysis on the 3rd, 7th and 14th d after MCAO; meanwhile, the behavior functions of rats at various time points were evaluated. Results The number of nestin positive cells in the hippocampus subgranular zone and subventricular zone and the expression of nestin protein from ischemia side brain in the FES treatment group significantly increased than those in the placebo stimulation group on the 7th and 14th d after MCAO (P<0.05). And statistical difference was noted on the 14th d on the behavior functional evaluation between the FES treatment group and the placebo stimulation group (P<0.05). Conclusion FES may enhance the endogenous proliferation of the neural stem cells within the brain in rats with acute cerebral infarction and improve the behavior function in rats, which may be one of the mechanisms of FES on improving the neural function after cerebral infarction.

OBJECTIVETo analyze the differences of risk factors on congenital heart defect (CHD)between floating population and permanent residents in Guangdong.

METHODSA multicenter case-control study was carried out to investigate the risk factors of CHD in floating population and in permanent residents. Data was from 34 Guangdong CHD Monitoring Network centers during the year of 2004 to 2011. Exposed information related to the parents at pre-pregnancy and early pregnancy periods, was collected, using the same questionnaire survey methodology in the two populations. Possible risk factors were analyzed by univariate analysis and multivariate non-conditional logistic regression(ENTER method)methods. Risk factors were compared between the two populations.

RESULTSTotally, 855 CHD cases and their controls from the floating population, as well as 1673 cases and their controls from the permanent residents were included in this study. Age of the children under study was defined from 28th week of gestation to 1 year old postnatal. In the floating population, specific risk factor for CHD appeared as:maternal passive smoking in early pregnancy, while the specific protective factor as high family income. However, the specific risk factors would include: having diseases as maternal diabetes mellitus or syphilis, living in a newly (within half a year) decorated house or with fetal macrosomia in the permanent residents. High education level showed as a risk factor in floating population, however contrarily, as protective factor to the permanent residents. Except for the factors related to having fever of the mother and infant with low birth weight, factors as having history of deliveries more than two, with maternal virus infection, exposure to chemical agent and negative bearing history etc., have higher OR values in floating population than in the permanent residents.

CONCLUSIONSignificant differences of risk factors for CHD were noticed between floating population and the permanent residents, which have their individual specific risk factors. Most of the ORs appeared higher in floating population than in the permanent residents.
