OBJECTIVE To prevent and control hospital cross-infection and hematogenous disease dissemination during oral cavity procedures.METHODS The problems that existed universally in instrument treating processes during oral cavity procedures were taken seriously.The perfect management rules and regulations were established.The instructions of technical operation were carried out strictly.We strengthened own-self occupation protection and implemented the standard prevention isolation principle.We guaranteed oral cavity synthesis method to implement,such as the instrument cleaning,disinfection,and antiseptic quality.RESULTS The hospital infection occurred in the oral cavity procedures could be reduced and avoided fundamentally through implementing infection control measure.The medical safety could be ensured.CONCLUSIONS The personnel standard diagnosing and treating operation of medical care should be established in hospital.The idea of disinfection and isolation asepsis should be enhanced.Own-self occupation protection must be required strictly.It is extremely important to control the infection during the oral cavity procedures.

OBJECTIVE: To extract effective constituent of Magnolia offcinalis and to identify its structure.METHODS: Ultrasound extraction was used to extract magnolol and honokiol from M.officinalis and the extracts were isolated using polyamide column chromatography.The content of magnolol and honokiol were determined using RP-HPLC.RESULTS: The optimal extractive condition was moderate ultrasonic,95% alcohol,8-fold solvent,extracting for three times,each time for 30 min.The extraction rates of phenols,magnolol and honokiol were 1.92%,1.26% and 0.66%,respectively.Honokiol was obtained by polyamide column chromatography.CONCLUSION: The method is simple,stable and supply reference for the extraction and identification of M.officinalis.

The contents of the components in waste eel bone from roast eel were determined. Optimal conditions for extracting eel bone oil from waste eel bone as raw material, purifing the polyunsaturated fatty acids (PUFA) concentrates from eel bone oil via salt-forming with urea complexation, and preparation of microcapsules containig PUFA concentrates from eel bone oil by spray drying were investigated systematically. The results showed that the technique was easy to carry out, the complete yield for extracting eel bone oil was above 76%, the contents of EPA and DHA in PUFA purified from eel bone oil increased from 7. 4% to about 45%, the recovery of EPA plus DHA was 64% , the content of PUFA from eel bone oil in the microcapsuls was about 26. 2%, and its antioxidative stability was higher than that of mixture of PUFA concentrates without capsulizing.

Objective To assess the effect of relaxation training combined with listening to music on postoperative rehabilitation of patients with liver cancer. Methods Patients who met the inclusion and exclusion criteria (52 cases) were divided into the experimental group and the control group with 26 cases in each group.The control group received routine postoperative nursing.The experimental group was given relaxation training combined with listening to music based upon routine nursing.The pain degree,time of ambulation,recovery of gastrointestinal function and bladder function and related postoperative complica-tions were compared between the two groups. Results The experimental group had less pain,earlier time of ambulation,shorter time for recovery of gastrointestinal function, indwelling gastric tube and urinary catheter(P < 0.01 ).Incidence rate of incision,bile leakage and intra-abdominal hemorrhage were not statis-tically different between the two groups (P > 0.05). Conclusion Relaxation training combined with lis-tening to music can facilitate the postoperative rehabilitation process of patients with liver cancer.

The inhibitory effect of the crude phycoerythrin(PE) on the frequency of PCE micronucleus induced by CP and its antitumor effect on mice bearing S 180 sarcoma were studied. The result showed that the PE could decrease significantly the frequency of PCE micronucleus with a fair dose-effect relationship, and showed obvious antitumor effect on S 180 bearing mice with an inhibitory rate 44%.

OBJECTIVE To discuss the possibility of HBV contaminating environment and transmission through the polluted surroundings. METHODS On the basis of that ascertain the contaminated environment by HBV marker(HBVM) and the relationship between HBVM and HBV infectivity in the blood,to discuss the probability of HBV contaminating and be spreading through the circumstance. RESULTS The positive rate of HBsAg and HBeAg was 26.39% and 11.11%,respectively in these specimens.While all of samples in control group were negative.The HBV DNA positive rate was 73.72% and 100.00%,respectively in the positive blood specimens of HBsAg and HBeAg.The infectivity was 0-10~9 and 10~2-10~9 ID/ml,respectively. CONCLUSIONS The blood worktable surface is contaminated by HBVM.The pollution is from patients′ blood.So the probability exists that HBV is transmitted through environment pollution.

Objective To study the antitumor effect and the mechanism of the polysaccharide from Gloipeltis furcata on H_(22),tumor bearing mice.Methods The polysaccharides from Gloipeltis furcata were administered by oral route in mice bearing H_(22) tumor.The treatments lasted for 7 days.The inhibition rate against H_(22) tumor and the indices of thymus, spleen and liver were measured.In addition,the levels of antibodies against H_(22) tumor and GPT in serum,and GPT,GOT,MDA and SOD in liver were measured using commercially available kits.Results The administration of the polysaccharides from Gloipeltis furcata(200 mg?kg~(-1)?d~(-1) and 400 mg?kg~(-1)?d~(-1) ) for 7 days,the inhibition rates of H_(22) tumor were 35.64%(P

Objective To investigate the changing trend of incidence and the relevant factors in fetal macrosomia. Methods 84 883 newborns during Jan. 1,1970 to Dec. 31,1999 were used to analyze the incidence of fetal macrosomia,the average birth weight,the percentage of superior fetal macrosomia, the distribution of gestational age, the rate of cesarean section and the vaginal delivery, the relevant factors of fetal macrosomia. Results All the cases were divided into 3 groups, one group from 1970 to 1979, the second one from 1980 to 1989, the third one from 1990 to 1999. The incidence of fetal macrosomia for three groups were 2. 6%, 6. 9% and 13 2% ( P
