This study was aimed to observe the promotion effect of wound healing retention enema for postoperative anal fistula by modifiedWu-Wei Xiao-Du(WWXD) decoction, in order to explore its mechanism. A total of 60 patients who met the inclusion criteria were randomly divided into the treatment group and control group, with 30 cases in each group. Patients in both groups were diagnosed as simple low anal fistula and treated with low anal fistula incision. The retention enema of 30 mL modified WWXD decoction or complexHuang-Bai fluid were given once a day for postoperative dressing changes. Detailed observations and scores were made on wound exudate, color, and itching around the anus. The comparisons were made on carrion off time, new epithelium time, rate of wound-reducing, wound healing time, and the total clinical efficacy 21 days after operation. The results showed that the wound exudate on the 7th and 14th postoperative day was better than that of the control group. There was no significant difference on the 21st day between two groups. The wound color of the treatment group was better than that of the control group on the 7th and 14th postoperative day. The itching around anus of the treatment group was better than that of the control group on the 7th, 14th and 21st postoperative day. The carrion wound off time and new epithelium time of the treatment group were earlier than that of the control group. There was no significant difference on the rate of wound-reducing. There were no significant differences on the total clinical efficacy 21 days after operation as well as the total average healing time of both groups. It was concluded that modified WWXD decoction can shorten the inflammation phase, reduce the wound exudate and itching, promote early carrion fall and as well as the wound healing.

OBJECTIVETo investigate the neurodevelopmental outcome of preterm infants who were discharged from neonatal intensive care unit (NICU) at 1 year of age and the impact factors contributing to the neurodevelopmental outcome and to study whether early intervention can improve the neurodevelopmental outcome in preterm infants.

METHODSEarly intervention guidance and follow-up visits were performed after the preterm infants discharged from NICU. The infants received the infant development test of Child Development Centre of China (CDCC) for neurological development at 1 year of age. The neurodevelopmental outcome was evaluated based on mental development index (MDI) and physical development index (PDI). MDI and PDI > 85 was defined as normal, MDI or PDI between 70 and 85 as critical and MDI or PDI < 70 as abnormal. Social-domestic and clinical factors related to neurological development were analyzed by ANOVA or chi-square test. Potential high risk factors were analyzed with logistic regression. To investigate the effects of intervention compliance on neurological development, the infants were classified into two groups according to different intervention compliances. The good compliance group included infants who received a through familial intervention for more than 4 days weekly (30 minutes daily) and consulted with physicians more than 5 times in 1 year. The infants who did not receive the interventions as the good compliance group served as the bad compliance group.

RESULTSThis study consisted of 210 infants, with a mean gestational age of 33.2 +/- 2.6 weeks and a mean birth weight of 1923.3 +/- 558.8 g. Normal, critical and abnormal neurological development occurred in 123 cases (58.6%), 61 cases (29.0%) and 26 cases (12.4%) respectively. Eighteen infants (8.6%) had mental lag and 9 (4.3%) had cerebral palsy (CP). The MDI and PDI scores of the good compliance group (111 cases) were 97.15 +/- 17.38 and 94.23 +/- 18.55 respectively, which were markedly higher than those of the bad compliance group (89.87 +/-18.92 and 87.20 +/-19.12; P < 0.05). The incidence of CP (3/111, 2.7%) in the good compliance group was lower than that of the bad compliance group (5/99, 6.1%) although there were no statistical differences. Parents' education level, multiple birth, serious intracranial hemorrhage and apnea were risk factors for adverse neurodevelopmental outcome.

CONCLUSIONSPreterm infants discharged from NICU are a high risk group of neurodevelopmental disablement. Early intervention can improve the neurodevelopmental outcome of perterm infants at high risk.

OBJECTIVETo evaluate the short-term and long-term effects of dense endoscopic variceal ligation (DEVL) for bleeding esophageal varices.

METHODSPatients with acute or with a history of esophageal variceal bleeding underwent regular DEVLs with a 2-3 week interval between 2 sessions until their varices disappeared at the lower 5-6 cm part of the esophagus. Follow-up study and gastroscopy were performed at 3, 6 and 12 months after the final DEVL in all patients. The results at 3 months were classified as short-term effects and those after 6 months as long-term ones.

RESULTS126 patients underwent DEVLs with 403 sessions and 3641 ligations; each patient was ligated with a mean of 3.2 sessions and at 28.9 points. The cure rate of acute variceal bleeding was 100.0%; short-term rate of variceal eradication was 94.4% and variceal rebleeding occurred in 3.9% patients. After a mean of 22.3 months follow-up period, the recurrence of esophageal varices was observed in 11.9% patients, but the variceal rebleeding rate was only 3.2% and no patients died from it.

CONCLUSIONDEVL was very useful and effective in both short-term and long-term variceal eradication and prevention of variceal rebleeding.

OBJECTIVETo investigate the therapeutic effects of acupuncture combined with nerve block for treatment of lumbar disc herniation.

METHODSNinety cases of lumbar disc herniation were randomly divided into three groups: acupuncture combined with nerve block group, acupuncture group and nerve block group, 30 cases in each group. The acupuncture combined with nerve block group was treated with acupuncture combined with nerve block therapy, L2-L5 Jiaji (EX-B 2), Zhibian (BL 54), Huantiao (GB 30), Yanglingquan (GB 34) etc. were selected for acupuncture, affected nerve root, sciatic nerve or common peroneal nerve were selected for nerve block with anti-inflammation-analgesic injection; the acupuncture group was treated with acupuncture only; the nerve block group was treated with nerve block only. After 4 weeks of treatment, the visual analogue scale (VAS), Oswestry lumbar dysfunction index (ODI) and modified MacNab standard were compared to evaluate the therapeutic effects of three groups.

RESULTSThe VAS and ODI in all groups were significantly decreased after one week, two weeks and four weeks of treatment (all P<0.01); after one week of treatment, the scores of VAS and ODI in nerve block group and acupuncture combined with nerve block group were significantly lower than those of acupuncture group (P<0.05); after two weeks and four weeks of treatment, the scores of VAS and ODI in acupuncture combined with nerve block group were significantly lower than those of acupuncture group and nerve block group (P<0.05). The effective rate and excellent and good rate of the acupuncture combined with nerve block group were significantly higher than those of acupuncture group and nerve block group (both P<0.01).

CONCLUSIONThe nerve block therapy and acupuncture are effective methods for treatment of lumbar disc herniation, while it has a better effect when these two treatments are combined used.

OBJECTIVETo investigate the mechanisms of enhanced antileukemia activity of conditionally replicating adenovirus (CRAd) by interleukin-24 (IL-24).

METHODSThe ability of CRAd ZD55 to infect leukemia cells was detected by flow cytometry. The expressions of vascular endothelial growth factor (VEGF) in leukemia cells treated with PBS, ZD55, ZD55-IL-24, and an adenovirus carrying IL-24 (Ad-IL-24) were determined by Western blot analysis. Animal xenograft tumor model was established by Mutz-1 cell line.Deparaffinized tumor sections were incubated with anti-CD31, and VEGF antibody, followed by immunohistochemistry analysis.

RESULTThe GFP-positive cells were 5.1% and 42.3% in Mutz-1 cells treated with ZD55-EGFP vector at MOI of 10 and 100 for 48h, respectively. ZD55-IL-24 treatment resulted in the marked down-regulation of VEGF protein expression and ZD55 inhibited VEGF slightly; however, there was no change observed in the cells treated with Ad-IL-24. Immunohistochemistry analysis showed that Ad-IL-24 inhibited slightly angiogenesis and ZD55 treatment resulted in significant inhibition of angiogenesis. ZD55-IL-24 treatment almost completely inhibited angiogenesis in tumor tissues.

CONCLUSIONIL-24 enhances the antileukemia activity of ZD55 by inhibiting VEGF protein expression and angiogenesis in vitro and in vivo.

OBJECTIVETo investigate the effects of procyanidins on proliferation and apoptosis of a hormone-dependent prostate cancer cell line LNCaP in vitro.

METHODSLNCaP cells were cultured in the presence of procyanidin (at 100, 200 and 300 microg/ml, respectively). After 24, 48 and 72 h of culture, the morphological changes of LNCaP cells were examined, and the inhibition of cell proliferation was measured by MTT assay and cell apoptosis evaluated by flow cytometry.

RESULTSAfter procyanidins treatment, some LNCaP cells presented characteristic morphological changes. Procyanidins inhibited the growth of LNCaP cells in a concentration- and time-dependent manner. Flow cytometry analysis showed that procyanidins induced apoptosis of LNCaP cells and the percentage of apoptotic cells increased with the concentration of procyanidins administered and also the elongation of treatment time.

CONCLUSIONProcyanidins inhibit the proliferation and promote the apoptosis of prostate cancer cells.
