To study and compare the protective effects of Cordyceps sinensis from different habitats on acute injury of hepatic tissue induced by carbon tetrachloride ( CCl4 ) . Methods:The rat model of acute injury of hepatic tissue induced by CCl4 was established. The biochemical indicators of alanine aminotranferease ( ALT) and aspartate aminotransferease ( AST) in the serum and superoxide dismutase ( SOD) and L-glutathione( GSH) in the liver tissue were detected, and the liver tissue HE staining was used for the histopathology determination. Results:Compared with those in the model group, the levels of AST and ALT in the serum were sig-nificantly reduced, the levels of SOD and GSH in the liver tissue were notably increased, and the necrosis of liver cells was improved in Cordyceps sinensis groups at low, medium and high dose from different habitats (P<0. 05), however, the differences between the two different habitats were not significant (P>0. 05). Conclusion: Cordyceps sinensis from Qinghai and Tibet shows some positive differences in the protective effect on the acute chemical liver injury induced by CCl4 in rats,however, the differences are not remarka-ble.

Objective:To observe the clinical efficacy of moxibustion with seed-sized moxa cone plus opioid drugs for moderate-to-severe cancer pain, and the effect on immune function in patients with cancer pain. Methods: A total of 80 patients with moderate-to-severe cancer pain were randomized into an observation group and a control group by the random number table method, with 40 cases in each group. Both groups were treated with opioid drugs for analgesia according to the standardized management principles for cancer pain. In addition, the observation group was given moxibustion with seed-sized moxa cone. The treatment was performed once a day, continuous 5-day treatment with a 2-day interval constituted a treatment course, and a total of 2 courses were performed. The score of numerical rating scale (NRS) and 24 h equivalent morphine consumption was compared between the two groups before treatment, after 1 treatment course and after 2 courses of treatment. The immune functions were compared between the two groups before and after 2 courses of treatment. Results: During the treatment, there were 3 dropouts in the control group, and 2 dropouts in the observation group. Before the treatment, there were no significant differences in the NRS score and 24 h equivalent morphine consumption between the two groups (both P>0.05). The NRS scores of both two groups were quite stable during the whole treatment period, and there was no significant difference in the intra-group comparison after treatment (both P>0.05), and there was no significant difference between the two groups at the same time point (both P>0.05). In the control group, the 24 h equivalent morphine consumption showed an increasing trend. The dosage after 1 treatment course and 2 courses of treatment was statistically different from that before treatment in the control group (both P<0.01). There was no significant change in the mean 24 h equivalent morphine consumption in the observation group compared with that before treatment (both P>0.05). After 2 courses of treatment, the 24 h equivalent morphine consumption in the observation group was significantly lower than that in the control group at the same time point (P<0.05). Before treatment, there was no significant difference in the levels of T lymphocyte subsets (CD3+, CD4+ and CD4+/CD8+) between the two groups (all P>0.05). After treatment, the levels of T lymphocyte subsets (CD3+, CD4+ and CD4+/CD8+) in the control group were lower than those before treatment (all P<0.05), while the levels in the observation group were higher than those before treatment, and the levels of CD3+ and CD4+ were significantly different from those before treatment (both P<0.05). After treatment, the levels of T lymphocyte subsets (CD3+, CD4+ and CD4+/CD8+) of the observation group were significantly higher than those of the control group at the same time point (all P<0.05). Conclusion: Moxibustion with seed-sized moxa cone can reduce the dosage of opioid drugs used in patients with moderate-to-severe cancer pain and improve their immune functions.

Objective To investigate the clinical efficacy of hemocoagulase for severe hemorrhagic cystitis (HC) following allogeneic hemotopoietic stem cell transplantation (HSCT). Methods Twenty patients undergoing allogeneic HSCT developed severe HC with an onset time of 14 to 70 days, all patients received the treatment of hemocoagulase (1 U ivgtt q12 h × 5 d). The urine speciments reserved before and after hemocoagulase were examined by naked eye and microscope to evaluate the efficacy. Results Twenty patients received the treatment of hemocoagulase. The HC was cured in 18 patients, improved in 1 patient and uncontrolled in 1 patient. For the patients with response, macroscopic hematuria disappeared at a median of 28 days (4-127 days) after the treatment. All procedures were tolerated well and no severe adverse effect was observed. Conclusion Hemocoagulase seems to be a safe and effective drug for severe HC following HSCT.

Objective To analyze the curative effect of simultaneous liver and kidney transplantation (SLKT) for patients with end-stage liver and kidney diseases and liver cirrhosis patients with hepatorenal syndrome.Methods All SLKTs (n=21) performed at our center from January 1999 to December 2010 were reviewed and SLKT outcomes were compared with those of kidney transplantation (KT) (n=609) and liver transplantation (LT) (n=133) performed during the same period.Results There were 3 deaths due to infection 2 weeks, 6 months and 5 years respectively after operation. One patient died due to multiple organ dysfunction syndrome 2 weeks after operation. One patient was dead 5 years after operation because of rejection. MELD level between SLKT and LT had no significant difference, but serum creatinine in SLKT group was significantly higher than in LT group (516.0±329.9 vs 111.4±138.1 mmol/L, P<0.01). The 1-year acute kidney rejection rate and rate of delayed graft function (DGF) of the kidney had no significant difference between SLKT group (0 vs 9.5 %) and KT group (6 % vs 17.3 %). There was no significant difference in one-, 3- and 5-year patient survival rate between SLKT group (87.7 %, 67.8 % and 67.8 %) and LT group (84.2 %, 73.5 % and 69.4 %).Conclusion SLKT is a safe and effective treatment for end-stage liver and kidney diseases.
