Comparative analysis of characteristic of species and esterase-isoenzyme of isolates of Polyporus umbel-latus from different regions were processed. The results indicated that isolates of Jizhaoling ( Z) and Zhushiling (ZJ) have significant differences in characteristic, and enzymatic band types of the two species also have significant differences. The homology at genetics between the two isolates is 0% , and consanguinity between the two i-solates is the farthest.

Viral hepatitis was the most common infectious disease in china. But the diagnosis and treatment were varied because the viral hepatitis patients were hospitalized in different kinds of hospital such as infectious disease hospital, general hospital and Chinese medical hospital. It was necessary to know clinical characters and information of viral hepatitis patients in different hospitals. The general information, subtype distribution, prognosis, complication, medication and relations of onset with solar term from 41 180 viral hepatitis patients based on HIS data were analyzed. It was found that the age of patients between 18 to 59 years old was most; most patients were males. The national basic medical insurance was the most type of payment. The outcome of viral hepatitis in the youth and female were better than that in the old and male. Acute hepatitis was easer to restore than chronic hepatitis. Liver cirrhosis and hepatocellular carcinoma were the two most complications. The peak of onset was during summer solstice, slight heat and great heat. The most common Chinese medicine was Diammonium glycyrrhizinate and the most common western medicine was reduced glutathione. The combination of D. glycyrrhizinate with reduced glutathione, polyene phosphatidylcholine and thymosin was the main pattern. But It was not knew if the combination of western and Chinese medicine was the most effective therapy to protect liver function. It was necessary to take deeply research of the relationship between the combination therapy and their effectiveness.

OBJECTIVETo observe the development of arrhythmia induced by ischemia/reperfusion (I/R) of the right coronary artery in rabbits and the intervening effect of Chinese medicine Qiangxin Fumai Granule (QFG), a Chinese preparation for activating yang and promoting blood circulation, on it.

METHODSRabbit right coronary artery I/R model was adopted. Forty healthy adult rabbits were randomly divided into 5 groups, the sham-operation group, the model group, the atropine group, the high-dose QFG group, and the low-dose QFG group, eight in each group. The drugs were administered via duodenal perfusion 10 min after ischemia. The changes of AA interval before and after medication were observed and the scores of arrhythmia were calculated.

RESULTSDuring ischemia period, AA interval prolonged for more than 40 ms in the model group, and the scores of arrhythmia showed a rising trend along with the prolonging of ischemia, with the presence of atrial-ventricular block (AVB) and aggravating of sinus and atrial arrhythmia; during reperfusion period, the incidence of AVB decreased, and AA interval somewhat decreased. The AA intervals and scores of arrhythmia in the high and low-dose QFG groups were significantly lower than those in the model group respectively (P < 0.01 or P < 0.05).

CONCLUSIONQFG is beneficial for shortening AA interval and preventing arrhythmia induced by I/R.

AIMTo evaluate in vitro release of lycopene microcapsules. Pharmacokinetic parameters of lycopene microcapsule and lycopene powder as reference were estimated after a single dose of oral administration to dogs. The relationship between in vitro dissolution and in vivo absorption was investigated.

METHODSThe content of lycopene in the release medium was determined by UV spectroscopy method. Health hybrid male dogs were used as experiment subjects and lycopene powder used as standard to estimate the pharmacokinetics of lycopene microcapsules. HPLC method was used to assay the concentration of lycopene in dog plasma. Pharmacokinetics parameters were estimated by 3P87 program. The drug release percentage in stimulated intestinal fluid was compared with the absorption at a given time point.

RESULTSThe release profiles of lycopene from microcapsule showed that the lycopene gelatin microcapsule exhibited enteric property. The pharmacokinetics parameters estimated after oral administration of lycopene powder and lycopene microcapsule in a single dose of 2.5 mg x kg(-1) body weight to dogs were 7.30 h, 15.06 h for T1/2alpha; 28.10 h, 46.76 h for T1/2beta; 22.32 h, 41.03 h for T(max); 1.67 microg x h x L(-1), 2.08 microg x h x L(-1) for AUC(0-infinity), respectively. The concentration-time curves could be fitted to a two-compartment model for both the lycopene powder and the lycopene microcapsule analyzed by 3P87 program. The relationship between in vitro dissolution and in vivo absorption was found to have good correlation (r = 0. 981 9) was found.

CONCLUSIONIt could be concluded that lycopene microcapsule was a sustained release dosage form. The result of release in vitro could be used to predict the absorption in vivo.

OBJECTIVETo summarize the clinical experience from treatment of patients with severe acute respiratory syndrome (SARS).

METHODSRetrospective analysis of seven patients with SARS in Ditan hospital treated since April 22 in 2004 was performed.

RESULTSIn the 7 patients, 2 were male, 5 were female, and the average age was (35.3 plus/minus 11.3) years. The main clinical manifestations were fever, cough, minor or serious dyspnea, nausea, signs of injury to other organs, and so on. The treatment regiments included oxygen, small dosage and short period of methylprednisolone (1 to 2 mg/kg), use of ventilator, psychological intervention, and treatment of underlying diseases, after which, all the 7 patients recovered.

CONCLUSIONRational use of methylprednisolone and timely use of ventilator were the key steps of treatment.

OBJECTIVETo analyze several methods of wound repair for deep partial thickness burn wounds retrospectively, so as to evaluate the significance of improvement of wound microcirculation on wound healing.

METHODS(1) 2,976 burn patients admitted to our department were enrolled in the study, among them 614 undertook tangential excision, 32, eschar abrasion, 86 allo-skin coverage after debridement, 1836 tropical application of silver sulfadiazine and 408 with traditional Chinese medicine (Jing Wan Hong ointment) with gauze bandage. The results of the management with different methods were compared. (2) Rat model with deep partial thickness burn was reproduced and topical application of silver sulfadiazine was given. The rats were randomly divided into control (n = 10, with normal saline injected via caudal vein within 5 minutes postburn), and treatment (n = 10, with batroxobin injected via caudal vein within 5 minutes postburn) groups. The blood flow perfusion unit in the wound skin was measured before burn and at 0.5 to 72 postburn hours by Laser Doppler. The wound healing rate, contraction rate and wound healing time in each group were calculated on 14 and 18 postburn days (PBDs). The number of hair follicles after wound healing was observed by histological method.

RESULTS(1) The burn wound treated by tangential excision healed within 2 to 3 post operation weeks (POWs), with the healing rate of 94.8% in patients with burn covering 50% - 70% TBSA and 93.4% in those with burn of 80% approximately 98% TBSA. The healing time of patients with allo-grafts coverage after eschar abrasion was 13.8 +/- 2.1 days without scar formation. The wound healing time was 18.0 +/- 2.3 day in 82 patients with allo-graft coverage after debridement, and it was 26.0 +/- 3.2 days with subeschar healing in 1658 patients with topical application of silver sulfadiazine. Infection in burn wound was encountered in most patients undergoing traditional Chinese medicine bandage treatment with wound healing time of 26.0 +/- 2.8 days in the lower extremities. (2) The blood flow perfusion unit of the rats in the treatment group was significantly higher than that in the control group (P < 0.01). The wound healing rate in treatment group on 14 and 18 PBD was obviously higher than that in the control group (P < 0.01). But the wound contraction rate in the two groups was similar (P > 0.05). The wound healing time in treatment group was much shorter than that in control group (P < 0.01). A few hair follicles remained in the dermis of the rats in the control group on 30 PBD, and the number was evidently smaller than that in the treatment group (P < 0.01).

CONCLUSIONEarly tangential excision and eschar abrasion remained better methods in the management of deep partial thickness burn wounds, as they could ameliorate burn wound infection, shorten treatment period, raise wound healing rate and quality. Application of batroxobin could accelerate wound healing rate by improving wound microcirculation in deep partial thickness burn wound.
