OBJECTIVETo investigate the antitumor effects of koumine in mice bearing H22 solid tumor and its effect on the immune system of the mice.

METHODSThe changes in spleen and tumor weights and blood cell count were observed after koumine treatment in BALB/c athymic mice bearing H22 solid tumor, using normal saline solution and 5-Fu as the controls.

RESULTSKoumine significantly inhibited the tumor growth in a dose-dependent manner. The spleen index and blood cell counts in koumine group showed no significant differences from those in the saline control group, but higher than those in 5-Fu group.

CONCLUSIONKoumine can significantly inhibit the growth of H22 solid tumor without obvious inhibitory effect on the immune system in mice.

BACKGROUND:The high level of matrix metalloproteinase 9 (MMP9) is thought to slow down the healing of diabetic foot ulcers. Whether it can influence the biological behaviors of skin fibroblasts and affect wound healing is stillunclear. The present study aimed to observe changes in the biological behaviors of rat dermal fibroblasts induced by high expression of MMP9 and to clarify the possible mechanisms of wound healing for diabetic foot. METHODS:A cellmodel of skin fibroblast with high expression of MMP9 was established by co-culture of high glucose (22.0 mmol/L) and homocysteine (100 μmol/L). A control group was incubated with normal glucose (5.5 mmol/L). Realtime PCR, ELISA and gelatin zymography were used to detect the MMP9 mRNA, protein expression and activity of MMP9. Flow cytometry, CCK-8, ELISA assay, scratch test and transwellwere used to detect cellproliferation, viability, collagen (hydroxyproline) secretion, horizontal migration and vertical migration of cells. The data were expressed as mean±SD. P value less than 0.05 was considered statistically significant. RESULTS:The expression of MMP9 mRNA, protein levels and the activity of MMP9 were much higher in the high MMP9 group than in the control group (7.05±1.02 vs. 1.00±0.00, 206.9±33.6 pg/mL vs. 40.4±5.9 pg/mL, and 1.47±0.13 vs. 0.57±0.12, respectively,P<0.01). The proportion of S-phase cells, proliferation index, cellviability, collagen (hydroxyproline) secretion, horizontal migration rate and the number of vertical migration cells were lower in the high MMP9 group than in the control group (P<0.01). CONCLUSION:Fibroblasts with a high expression of MMP9 decreased proliferation, activity, secretion and migration of collagens, suggesting that MMP9 may inhibit the biological behaviors of fibroblasts.

Objective To investigate the diagnosis and treatment of anticoagulation complication,heparin-induced thrombocytopenia (HIT),induced by low-molecular-weight heparin (LMWH) after joint replacement.Methods Retrospectively analyzed the clinical manifestations,treatment and prognosis of 4 patients after total knee arthroplasty (TKA) suffered from HIT induced by LMWH.Results The morbidity rate of HIT induced by LMWH was 0.3％(4/1376).Platelets were found less than 70 × 109/L after 4-9 d,minimum to 16 × 109/L.Different level of cardiorespiratory distress and lower extremity deep venous thrombosis all appeared.Once diagnosed,patients were immediately stopped using LMWH and replaced with argatroban,fondaparinux or rivaroxaban and warfarin.Deep vein thrombosis gradually disappeared and cured in 3 patients after treatment.One patient suffered cerebral hemorrhage and multiple pulmonary embolism,received craniotomy hematoma removal and decompressive craniectomy.But the patient didn't wake up after 1-month treatment,became a vegetative one.Conclusions HIT is rare but dangerous,which can result in deep vein thrombosis,pulmonary embolism,cerebral hemorrhage and other serious consequences.Early diagnosis and timely treatment can reduce the rate of disability and mortality.

Objective Investigate the prognosis of patients undergoing liver transplantation (LT) for end-stage autoirnmune liver disease (ALD).Method The clinical data of 45 patients with endstage ALD undergoing LT from April 2001 to March 2015 in the first affiliated hospital of Zhejiang University were analyzed retrospectively.The postoperative cumulative survival rate of the recipients was calculated,and the causes of death were analyzed.The postoperative rejections,new onset viral hepatitis and ALD recurrence were also analyzed.Result In 45 ALD recipients,33 cases survived and the postoperative 5-year cumulative survival rate was 78.8％.Causes for 12 dead cases were mnultiple organ failure,liver graft failure,respiratory complications,hemorrhage and hepatic artery embolization.In 45 ALD recipients,6 cases suffered rejection after operation with the incidence bing 13.3％.One case suffered new onset hepatitis B infection 8 years after opcration.One recipient suffered primary disease (primary biliary cirrhosis) recurrence 2 years after operation,and 1 recipient with primary disease (primary sclerosing cholangitis) developed into overlap syndrome.They all survived for a long term after active treatments.Conclusion Most LT recipients with endstage ALD can obtain a long term survival.Attentions should be paid to the immunosuppressive regimens in early period after LT,prevention of infection,rejection and postoperative new onset viral hepatitis,and timely diagnosis of primary disease recurrence.

Objective To evaluate the effects of color Doppler ultrasound guided percutaneous aspiration and absolute alcohol sclerotherapy on abdominal viscera cysts.Methods38 abdominal cysts in 33 cases were treated under Color Doppler ultrasound guided percutaneous aspiration and sclerotherapy with injection of absolute alcohol.Results After absolute alcohol treatment for 38 cysts in 33 cases,the cure rate was 89%,the efficacy rate was 100%.Con- clusion Color Doppler ultrasound Guided puncture sclerosing therapy of abdominal viscera cyst is a simple,safe and effective method.

OBJECTIVETo explore the dynamic changes of blood sugar and body's signs in streptozotocin diabetic animal models.

METHODSRat and mouse diabetic models were established by a single intraperitoneal (ip) injection and 5-day successive ip injections of streptozotocin respectively. Blood sugar levels were measured. The food consumption index (consumption of food/body weight) and the water consumption index (consumption of water/body weight) were calculated.

RESULTSSixty five point zero percent male rats received streptozotocin, 60 mg/kg ip, developed diabetes mellitus. The blood sugar remained in high level between the 15th day and the 25th day after injection, and it began to decline afterwards. By 5-day ip injections of streptozotocin, 40 mg/kg daily, 90.0% male mice developed diabetes mellitus. Dynamic changes of blood sugar of diabetic mouse were similar to those of rats, except that the blood sugar of mice did not decline as obvious as that of rats. The changes of water consumption index were in best fit with the changes of blood sugar in both models, with correlation index r>0.970.

CONCLUSIONThe blood sugar of diabetic animal model stayed in high level from the 15th day to the 25th day after the beginning of injection. And the period is suitable for observing effect of anti-diabetic drugs. The water consumption index can reflect the blood sugar levels of diabetes animals.

Biological characteristic of Salvia miltiorrhiza f. alba in field was studied. HPLC method was used to determine the lipophilic constituents (dihydrotanshinone, cryptotanshinone, tanshinone, tanshinone II (A) and miltione) and hydrophilic constituents (salvianolic acid, rosemarinic acid). The results showed that the fresh weight of S. miltiorrhiza f. alba which cropped for 2 years was decreased by 80.47%, while dry weight decreased by 79.42%. The normal diameter of the root was 0.3-0.5 cm, however, the diameter was 0.2-0.4 cm after 2 years, it was said that the decrease of the root diameter was the main reason for the decrease of the yield. The average contents of dihydrotanshinone, cryptotanshinone, tanshinone, tanshinone II (A), miltione, salvianolic acid and rosemarinic acid were decreased by 35.26%, 32.26%, 19.35%, 3.39%, 64.40%, 66.93% in plant which continuously cropped for 2 years, respectively. The yield and active constituents were mostly effected in the plant of S. miltiorrhiza f. alba, which continuously cropped for 2 years.
