Objective To study the immune state and correlated strategy of patients with hepatic cirrhosis and primary hepatic carcinoma.Methods 17 patients with hepatic cirrhosis and 8 patients with primary hepatic carcinoma(PHC) in our hospital were collected since 2002.The indexcs of immune function were detected in all patients and some were re-examined.Results It was found that although the immune index varied in patients suffering from severe liver diseases,some regularities were shown as follows:(1)CD4 and CD4/CD8 in T lymphocyte subset declined markedly(P

Though prokaryotic cells could hardly express recombinant human beta nerve growth factor (rhNGF-?) with a proper three-dimensional conformation, using of E. coli as a host for industrial production of rhNGF-? is controversial. Recombinant human beta NGF was expressed in E. coli and was refolded in vitro. The isolated products was shown to be consistent with those expressed and secreted by CHO cells in biochemical characters by SDS-PAGE, RP-HPLC, mass spectrometry, N terminal analysis and bioassay determined using DRG and PC12 cells. The products can be acquired with 95% purity, 1.8 ng/U biological activity from both expression system,which remain invariable biological activity when lyophilized in excipient and store at 37℃?2℃, RH 75%?5% for 3 months. Moreover, the product refolded from inclusion bodies of E. coli shows the predominance in homogeneity and the lower cost.

Objective: To summarize our experience on perioperative anesthesia management of patients with crush syndrome caused by earthquake under field condition. Methods: The clinical anesthesia data of 10 patients with crush syndrome caused by China Wenchuan earthquake, who were treated under field condition, were retrospectively analyzed, and our experience on perioperative anesthesia management was summarized. Results: After volume therapy, urine alkalization, and stabilization of internal environment, the 10 patients underwent debridement, decompression by fasciotomy or amputation under epidural anesthesia or brachial plexus block plus psychological therapy and moderate tranquillizer. During the operation, the patients showed smooth respiratory and cardiovascular characteristics without pain. Conclusion: Under field condition, regional anesthesia can provide adequate analgesic effect during and after the surgery. Early fluid resuscitation and life support are vital to the safety and life of patients.

Objective:To observe the efficacy of Chuankezhi injection combined with budesonide and formoterol fumarate powder for inhalation in the treatment of chronic obstructive pulmonary disease ( COPD) . Methods:Totally 120 patients with COPD were ran-domly divided into two groups:the observation group inhaled budesonide and formoterol fumarate powder for inhalation combined with intramuscular injection of Chuankezhi injection, and the control group inhaled budesonide and formoterol fumarate powder for inhala-tion. The treatment course was 28 days. The pulmonary function indices [ FEV1% expected value, FEV1 /FVC, 6 min walking dis-tance (6MWD)], the times of acute exacerbation and the adverse drug reactions during the treatment were observed and compared be-tween the two groups. Results:After the treatment, the lung function and 6MWD were improved in the two groups, and the improve-ment of FEV1% expected value in the treatment group was more obvious than that in the control group [(59. 7+12. 1)% vs (49. 8+11. 3)%, P<0. 05]. The number of patients with at least once of acute exacerbation was significantly reduced in the treatment group when compared with that in the control group (35% vs 62%, P<0. 01). The incidence of adverse drug reactions in the two groups showed no significant difference. Conclusion:Chuankezhi injection combined with budesonide and formoterol fumarate powder for in-halation can notably improve the lung function in the patients with COPD and reduce the times of acute exacerbation without effect on the incidence of adverse drug reactions.

Objective To analyze the genetic diversity of snail populations from five provinces in China mainland. Methods Genomic DNA was amplified by random primer and the products were electrophoresed by 8% polyacrylamide and stained by 0.6% silver nitrogen. The results were recorded and analyzed. Results The average similarity and match percentage among the nine snail populations were 0. 721 4 and 0. 680 9 respectively. The cluster trees showed that the nine snail populations could be divided into three groups ; snails from Dali of Yunnan Province and Puge of Sichuan Province were the first isolated group; snails from Fuqing of Fujian Province and Dongtai of Jiangsu Province were clustered into the second group; the other four populations from Anhui Province and snails from Yixing of Jiangsu Province belong to the last group. Conclusion There is a large diversity among smooth-shelled snails in China although close relationship exists. The cluster trees gained by different snail populations are basically the same and consistent with the distribution of these populations. However, further study should be carried out on the cluster of smooth-shelled snails from Dongtai of Jiangsu Province.

Objective: To evaluate the clinical effect of individualized enteral nutritional (EN) support in severe stroke patients.Methods: Totally 120 severe stroke patients with nutritional risk were divided into two groups according to single or double admission number.The 60 patients in the intervention group received an individualized EN with different formula and concentrations according to the clinical status,and supplemented trace elements as occasion required.In the routine group, the patients received EN with standard formula.The energy supply was 83-125 kJ· kg-1·d-1 in both groups.Blood albumin(Alb), pre-albumin(PA), hemoglobin(Hb) and vitamin C(VC) were examined before and after the 21-day nutritional support.The lung infection and gastrointestinal (GI) complications were observed, and the hospital stay and cost were recorded as well.Results: After 21 day''s nutrition support, the serum levels of Alb, PA and VC in the intervention group were not statisticly significant than before (P＞0.05), and the serum levels of Alb, PA and VC were significantly higher than those in the routine group(P＜0.05).The incidence of complications in the in the intervention group was lower than that in the routine group (P＜0.05), and the length of hospital stay and hospitalization was shorter than that in the routine group (P＜0.05).Conclusion: Individualized enteral nutritional support can significantly improve nutritional status, reduce inflammation reactions and GI complications in severe stroke patients, which is worthy of clinical use.

The incidence rate of hepatocellular carcinoma (HCC) is increasing around the world and tends to decrease in East Asia and several regions in China;however, China still has higher incidence rate and mortality rate of HCC than most countries.Studies have shown that long-term antiviral therapy can inhibit HBV replication to a very low level or help patients with HCV infection achieve sustained virologic response, which can further reduce the incidence rate of virus-related HCC.New evidence suggests that compared with nucleos(t)ide analogues, PEG-IFNα has a better effect of secondary prevention.Studies also indicate that interferons play an important role in tertiary prevention of virus-related HCC.This article reviews the epidemiological studies on virus-related HCC in recent years and the role of antiviral therapy in second and tertiary prevention and points out that adequate and effective antiviral therapy is the basis for preventing the development and recurrence of HCC.

Microcirculation is closely related to occurrence and development of disease, so it is of significance in noninvasive imaging of microcirculatory structure and function in vivo.Photoacoustic imaging is one of the main techniques in microcirculation imaging, which has the characteristics of high contrast, high detection depth and high sensitivity to tissue function.A review of the literature showed that photoacoustic technique can noninvasively image and quantitatively measure microcirculatory structure, vasoconstriction and vasodilation, concentration of hemoglobin, oxygen saturation, blood velocity and direction, oxygen metabolism level in a certain depth of living tissue in real time.Research progress in photoacoustic imaging of microcirculation in subcutis, cerebral cortex, tumor, eye and other tissues is reviewed in this paper.

Objective To review the recent studies on the suppressing function of breast cancer metastasis suppressor 1 (BRMS1) in breast cancer metastasis. Methods The recent literatures on the mechanisms of BRMS1 in the breast cancer that were published in and abroad were reviewed and summarized. Results BRMS1, similar to the other anti-metastasis genes, only suppresses the metastasis of breast cancer cells but has nothing to do with the growth of tumor. BRMS1 could suppress metastasis of tumor cells by reestablishing both the homospecific and the heterospecific gap junctional intercellular comminications (GJIC) and by altering the expressions of relevant metastasis genes in the breast cancer. Conclusion Further studies on BRMS1 may be helpful to understand the metastasis of breast cancer, which may provide a new way for the diagnosis and treatment of breast cancer.
