To study the effect of Siwu decoction on the function and expression of P-glycoprotein (P-gp) in Caco-2 cells. The Real-time quantitative poly-merase chain reaction (Q-PCR) was used to analyze the mRNA expression of MDR1 gene in Caco-2 cells. Flow cytometer was used to study the effect of Siwu decoction on the uptake of Rhodamine 123 in Caco-2 cells, in order to evaluate the efflux function of P-gp. Western blotting method was used to detect the effect of Siwu decoction on the P-gp protein expression of Caco-2 cells. Compared with the blank control group, after Caco-2 incubation with Siwu decoction at concentrations of 3.3, 5.0, 10.0 g x L(-1) for 24, 48, 72 h, the mRNA expression of MDR1 was up-regulated, suggesting the effect of Siwu decoction in inducing the expression of MDR1. After the administration with Siwu decoction in Caco-2 cells for 48 h, the uptake of Rhodamine 123 in Caco-2 cells decreased by respectively 16.6%, 22.1% (P < 0.05) and 45.4% (P < 0.01), indicating that the long-term administration of Siwu decoction can enhance the P-gp efflux function of Caco-2 cells. After the incubation of Caco-2 cells with Siwu decoction for 48 h, the P-gp protein expression on Caco-2 cell emebranes, demonstrating the effect of Siwu decoction in inducing the protein expression of P-gp.

Objective To observe the clinical efficacy of acupuncture plus hyperbaric oxygen in treating depression after cerebral stroke.Method A total of 120 patients with depression after cerebral stroke were randomized into a treatment group of 60 cases and a control group of 60 cases. The treatment group was intervened by acupuncture plus hyperbaric oxygen, while the control group was intervened by Fluoxetine. Before the treatment, and respectively after 14-d and 28-d treatments, the patients were evaluated by Hamilton Depression Scale (HAMD) and National Institute of Health Stroke Scale (NIHSS), and the therapeutic efficacies were compared between the two groups. Result The treatment group was significantly superior to the control group in comparing therapeutic efficacy (P<0.01). After 1 course of treatment, the HAMD and NIHSS scores dropped significantly in the treatment group (P<0.01); the scores in the control group showed a declining tendency but without statistical significances (P>0.05). After 2 treatment courses, the HAMD and NIHSS scores were significantly different from those before the treatment in both groups (P<0.01), and the differences were more significant in the treatment group (P<0.01).Conclusion Acupuncture plus hyperbaric oxygen is effective in treating depression after cerebral stroke, and it can obviously improve the neural function.

Objective ] To study the molecular characteristics and antibiotic resistance of Salmonella diarrhea cases in sentinel hospitals through active surveillance system conducted by public health laboratory. [ Methods] Two sentinel hospitals were chosen for collection of stool specimens from food-borne infectious diarrhea cases and for Salmonella separation and detection immediately following serotyping and antimicrobial susceptible test ( AST ) on those isolates .Moreover , pulsed field gel electrophoresis ( PFGE) was used for the genetic homology analysis . [ Results] A total of 2 579 diarrhea specimens were collected and analyzed from 2010 to 2012, with 185 Salmonella isolates, covering 23 different serotypes (annual positive rates were 9.1%, 6.8%, 5.1%, with an average 7.2%).Salmonella enterica serovar Enteritidis(S.Enteritidis) and Typhimurium(S.Typhimurium) were the most common serotypes, of which 68.9% cases were seen in those aged 21 to 60 and 21.4% cases in those over 60 years old. 27.7%-96.9%S.Enteritidis and 2.6%-63.2% S.Typhimurium(P all <0.05) proved resistant to Nalidixic acid, Sultisoxazole, Streptomycin, Sulfamethoxydiazine, Gentamicinand Tetracycline. PFGE analysis on 22 S.Enteritidis strains showed 11 different clusters , while 20 S.Typhimurium strians showed 6. [Conclusion] S.Enteritidis and S.Typhimurium are the most common Salmonella serotypes, and molecular typing indicates the existence of clustering and sporadic outbreaks caused by dominance clones . We should be alert to early warnings on potential outbreaks of multiple-drug-resistant ( MDR ) S.Enteritidis.Active surveillance system based on public health laboratory should play an important role in the control of food-borne infectious diseases .

OBJECTIVESTo detect the loss of heterozygosity (LOH) of circulating DNA in the plasma of patients with hepatocellular carcinoma (HCC), and to assess its potential as a clinical predictive marker.

METHODSThree high-polymorphic microsatellite markers D8S277, D8S298 and D8S1771 located at chromosome 8p were selected to detect LOH in plasma DNA of 62 HCC patients. The associations between LOH and its clinicopathological features, including HBsAg, liver cirrhosis, serum AFP level, tumor size, tumor cell differentiation, and intrahepatic metastasis were also examined.

RESULTSIn plasma DNA of the 62 HCC patients, LOH was found at one or several loci in 36 (58.1%), and heterozygosity at D8S277, D8S298, and D8S1771 loci was 74.2% (46/62), 75.8% (47/62), and 69.4% (43/62), respectively. LOH frequency at D8S277, D8S298 and D8S1771 was 32.6% (15/46), 44.7% (21/47), and 46.5% (20/43), respectively. LOH in plasma DNA was more frequently detected in the patients with intrahepatic cancer metastasis than those without metastasis (62.5 percent vs. 26.1 percent, P < 0.05); however, no statistically significant correlations were observed between LOH at these loci and other clinicopathological features analyzed in this study.

CONCLUSIONSLOH at D8S298 in plasma DNA may be a potential predictive marker of intrahepatic metastatic recurrence after surgical resection of the HCC.

OBJECTIVETo investigate the effect of transcatheter hepatic arterial chemoembolization (TACE) therapy on the survival and prognosis of recurrent hepatocellular carcinoma (HCC) after surgical resection.

METHODSThe data of 130 surgically resected but recurrent HCC patients treated by TACE were reviewed retrospectively. The survival and influencing factors on the prognosis were analyzed.

RESULTSThe overall 1-, 3-, 5-year survival rates of these 130 patients were 83.0%, 45.5% and 17.6% respectively (median survival time 2.4 years). Ninty-four of the series were treated with TACE alone, which gave the 1-, 3- year survival rates of 76.4% and 37.1%, respectively (median survival time 2.1 years). Thirty-six out of 130 patients treated with TACE plus percutaneous ethanol injection (PEI), the 1-, 3-year survival rates were 100.0% and 66.5% respectively with a median survival time (MST) of 3.5 years. The survival of TACE plus PEI group was significantly better, and the mortality risk was significantly lower than that of TACE alone group (P < 0.05). The mortality risk of those with > 5 cm diameter recurrent tumor or with distant metastasis was significantly higher than those with < or = 5 cm diameter tumor or without metastasis (P < 0.05).

CONCLUSIONTACE combined with PEI may improve the survival of recurrent HCC patients.

OBJECTIVETo explore the synergistic interaction between MMP-3,VDR gene polymorphisms and occupational risk factors on lumbar disc degeneration.

METHODSA case-control study including 178 cases of lumbar disc degeneration and 284 controls was carried out through questionnaire and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technology. Additive model was used to analyze the synergistic interaction between gene polymorphisms and occupational risk factors.

RESULTSThe non-conditional logistic regression analysis showed that bending/twisting, whole-body vibration, heavy physical workload, alleles 5A of MMP-3 (6A5A/5A5A) and A of VDR-Apa (AA/Aa) were significantly associated with lumbar disc degeneration(OR = 4.06, 8.96, 5.46, 1.96 and 1.70, respectively, P < 0.05). There were synergistic interactions between the mutation genotype 5A of MMP-3 and whole-body vibration exposure, between the mutation genotype 5A of MMP-3 and bending/twisting, and between the mutation genotype A of VDR-Apa and whole-body vibration exposure (SI: 13.27, 2.91 and 2.35 respectively, P < 0.05).

CONCLUSIONPeople with the mutation genotypes 5A of MMP-3 and/or A of VDR-Apa may have the increased risk of developing lumbar disc degeneration if they are exposed to whole-body vibration and/or bending/twisting.

OBJECTIVETo observe the effects of traditional Chinese medicine mask combined with skin care in the treatment of facial pigmentation after burns.

METHODSForty-one patients with facial pigmentation after burns hospitalized from January 2009 to June 2010 were enrolled and divided into treatment group (n = 26, odd number) and control group (n = 15, even number) according to the visiting order. After cleaning, massaging, and steam spraying to faces, patients in treatment and control groups were respectively treated with traditional Chinese medicine mask developed by physicians in our hospital and common commercial beauty mask. Masks were removed when they became completely dry. The treatment was repeated every other day. Ten times made up a course of treatment. Three consecutive courses were carried out on each patient. Before treatment and at the end of each course, the skin color differences were measured with Vancouver Pigmented Scar Scale; image gray scale value of pigmented skin was measured with image analysis technique. Satisfaction degree acknowledged by both patients and physicians were recorded at the end of each course; adverse effects were recorded; and the overall efficacy between two groups was compared. Data were processed with chi-square test or t test.

RESULTSSkin color differences, image gray scale value of patients in treatment group were close to those in control group before treatment (with t value respectively 0.800 and 0.694, P values all above 0.05). Skin color differences, image gray scale value, and satisfaction degree acknowledged by both patients and physicians in treatment group were better than those in control group at the end of each course. At the end of the third course of treatment, the skin color differences in treatment and control groups scored 0.5 ± 0.4 and 1.1 ± 0.6, respectively, with image gray scale value of 55 ± 5 and 66 ± 6, respectively, which were statistically different from each other (with t value respectively 3.389 and 5.102, P values all below 0.01). The overall efficacy of the treatment group was 92.3%, which was much better than that of the control group (53.3%, χ(2) = 6.31, P < 0.05). No allergy caused by the traditional Chinese medicine mask was observed during the treatment.

CONCLUSIONSThe traditional Chinese medicine mask combined with skin care is effective for the treatment of facial pigmentation after burns.
