Xinmailong injection solution was invented at 1988 by prof. Li Shunan in Dali medical college. It was made from the material which has high biological activeness to the cardiac and vascular system. During the experimental shock caused by excessive loss of blood in monkey and dog, it was found by ECG that the T-wave of anterion lead on left chest elevated and became high and sharp after acute blood loss. Arterial blood pressure dropped to 8-5.3 kPa for dog and 8-5.3-2.7 kPa for monkey, changes of T-wave all recovered to near normal level after xinmailong solution was injected intravenously (0.05-0.2 mL/kg). These Results implied that xinmailong might improve the ischemia of myocardium induced by hemorrhagic shock.

The patient,a 11-year-old boy,presented with a 4-year history of erythema and vesicles on the face and arms as well as a 4-month history of tumor and ulcer on the extremities,accompanied by progressive fatigue and intermittent fever.The patient had a body temperature of 37.7℃.No lymph node involvement was observed.Cutaneous examination revealed minimally indurated pink-red patches on the face and nose and dusky red firm nodules and tumors of varying sizes on the extremities.The nodules ranged from 2.0 cm to 18 cm in diameter,some had necrosis and black crusts on the surface.Ulcers were observed in some of the larger nodules;many of the ulcers extended into the muscle layer.White purulent discharge was seen on the surface of many of the nodules.The lesions were sharply demarcated,firm,tender, and surrounded by small satelite nodules.Histologically,there were large quantities of irregularly shaped, middle-sized tumor cells with clear cytoplasm,large twisted nuclei and prominent chromatin,infiltrating from the epidermis to subcutaneous tissue.The tumor cells infiltrating the follicles and eccrine sweat glands were either distributed perivascularly in a nest shape,or dispersed.There were broken nuclei and reactive histio- cytic infiltration in the dermis and subcutaneous tissue.Immunohistologically,the tumor cells were positive for cytoplasmic CD3 around the nuclei,for CD56,CD45RO and T cell intracellular antigen-l,and partly for CD30,CD8 and Ki67.Epstein-Barr virus-encoded nuclear RNA was positive with in situ hybridization. TCR?-2 gene rearrangement was positive in these tumor cells.A diagnosis of hydroa vacciniforme-like primary cutaneous NK/T-cell lymphoma was made.Therefore,this is a case report of hydroa vaccini- forme-like primary cutaneous NK/T-cell lymphoma with primary involvement in the skin;the condition was slowly progressive over 51 months.

A reasonable and practicable quality standard was developed for mori liquid extract from different sources by TLC, HPLC and fingerprint technology. In TLC method, the compounds were separated on polyamide film using glacial acetic acid-water (1: 3) as mobile phase at a UV wavelength of 365 nm. All qualified samples had the spots of the same color as the control herb and substance. The RP-HPLC method was used to determine the content of mulberroside A with mobile phase of methanol-water (25: 75) at a wave-length of 326 nm. The mulberroside A was in good linear with a regression equation of Y = 46.965X (r = 0.999 6) in the range of 4.6 - 228 mg x L(-1). In 14 batches of samples, the mulberroside A in 4 batches of them was less than 0.5 g x L(-1), and was more than 2.0 g x L(-1) in the other batches. It was suggested that the content limit of mulberroside A should be no less than 1.5 g x L(-1). The HPLC fingerprints were evaluated by the similarities. It has found that the similarities of different mori liquid extracts were very low and the chemical diversity of mori cortex was the major factor of similarity. Moreover, the process impact was minimal. Thus the fingerprint was not included in this quality standard.

Objective With awareness, attitudes, and rice-intake behavior of Kaschin-Beck disease (KBD) and the analysis of the factors that influence KBD related rice-intake behaviors among resident's in Aba,this research could provide evidences for KBD-Control, and benefit the policy development related to KBD-Control.Methods Villages were chosen by proportional stratified random sampling from KBD monitoring villages among agriculture areas, pastoral areas, and farming & pastoral areas in Aba, Sichuan, in July 2009. Interview questionnaire of household survey, designed by research associates of this project, was used in this research for residents in endemic area of KBD in Aba. The questionnaire covered demographic and socio-economic characteristics, KBD knowledge and diet habits. Multi-level Variance Component Analysis was used to explore factors which would influence the KBD related rice-intake behaviors. Results A total of 1029 permanent residents were recruited in this research, among which the detection rate of KBD was 48.01％ (482/1004). Most of the patients lived in farming & pastoral areas(84.44％, 407/482). Pastoral residents had the least knowledge of KashinBeck disease, and the composition ratios ofGeneral andGood were 15.87％ (33/208)and 3.36％ (7/208),respectively. Still, people who were willing to have rice as staple food were 93.13％(935/1004). It indicated that only (50.40 ± 23.68)％ on average, of research subjects had the life style of rice intake. Ethnic, work status,language situation and attitudes to rice intake were influencing factors for rice-intake behavior. Conclusions The percentage of rice intake in Aba KBD epidemic areas is low. And to prevent KBD, the advocacy actions should be targeted at ethnic, work status, language situation, and attitudes to rice intake.

In the present study the nutritional status in 1723 inpatients were evaluated. The over nutrition in male, in the cadre, and in patients with cerebrooardiovascular diseases or with diabetes was significantly higher than that in female, in the staff members, and the patient changing the valve in heart with rheumatism, respectively. The over nutrition in patients with breast and colonrectal cancer was obviously higher than that in stomach carcinoma patients. The sum total of lymphocytes was reduced in middle malnutrition patients. The nutritional status was well compared with the abnormal ratio of hemoglobin and serum protein, and A/G reverse was increased in some middle malnutrition patients. The MAC, MAMC and TSF in all of the malnutrition patients were than that of 80% standarized value, and were all the same in the evaluation of body weight.

BACKGROUNDHydrogen sulfide (H 2 S) plays a protective role in chronic hemodialysis (CHD) patients. In this study, we further investigate the relationship between H 2 S and conventional protein kinase CβII (cPKCβII) in CHD patients with uremic accelerated atherosclerosis (UAAS).

METHODSA total of 30 healthy people, 30 CHD patients without AS and 30 CHD patients with AS (CHD + AS) were studied. Plasma H 2 S was measured with a sulfide sensitive electrode, and cPKCβII membrane translocation was detected by Western blotting.

RESULTSPlasma H 2 S in CHD + AS group was significantly lower than that in CHD patients. cPKCβII membrane translocation in CHD + AS group increased significantly compared with CHD group. Plasma H 2 S concentration was negatively correlated with cPKCβII membrane translocation in CHD + AS patients.

CONCLUSIONSThese findings suggest a possible linkage between H 2 S metabolism and cPKCβII activation, which may contribute to the development of UAAS in CHD patients.

OBJECTIVETo observe the effect of RNA interference on CHK1 and CHK2 expression and change of G2/M phase arrest in esophageal carcinoma cells after irradiation.

METHODSFour sequences short hairhip RNA (shRNA) of each CHK1 and CHK2 genes were constructed and connected with vector of pENTR/U6 plasmid, respectively, and then transfected into Eca109 cells with lipofectamine 2000 reagent. Protein and mRNA expression of CHK1 and CHK2 genes were detected with Western blotting and RT-PCR, respectively. Cell cycling was measured by flow cytometry after 5 Gy irradiation. Cell survival rate after 5 Gy irradiation was evaluated by clonegenetic assay.

RESULTSFour shRNA vector each of CHK1 and CHK2 genes were successfully constructed and transfected into Ecal09 cells, respectively. Protein expression of CHK1 and CHK2 were obviously decreased. Their mRNA expressions were also decreased after transfected with shRNA of CHK1 and CHK2. Arrest of G2/M stage in Eca109 cells were obviously decreased only in cells transfected with CHK1 shRNA but not with CHK2 shRNA at 12 h after 5 Gy irradiation. In first progeny Eca109 cells transfected with CHK1 and CHK2 shRNA, expression of CHK1 and CHK2 protein was also decreased. The level of phosphorylated CHK2-T68 expression was decreased at 1 h after 5 Gy irradiation, and at 72 h only transfected with CHK2 shRNA but not with CHK1 shRNA. Phosphorylation level of CHK1-S345 was not increased after transfected with CHK1 or CHK2 shRNA, but arrest of G2/M stage still remained at 12 h after 5 Gy irradiation and at 72 h accordingly. The cell survival rate was decreased in Eca109 cells transfected with CHK1 or CHK2 shRNA after 5 Gy irradiation.

CONCLUSIONAfter transfected with shRNA of CHK1 or CHK2, their expressions of mRNA and protein in Ecal09 cells are markedly inhibited and this inhibition effect can be observed in their first progeny cells and at least hold for 3 days. Arrest of G2/M phase can be reduced after irradiation when teansfected with shRNA of CHK1 and the radiosensitivity of Ec109 cells can be increased.
