Objective To study the appropriate antibiotic for prophylactic use in cesarean section. Methods The effects and side effects of prophylatic antibiotics in 1 266 cesarean section were studied retrospectively. Six regiems were engaged: (1) Penicillin and Ampicillin; (2) Mezlocillin sodium; (3) Sulbactam and Ampicillin; (4) Ciprofloxacin; (5) Clindamycin; (6) Cefacidal. Results The duration of postoperative body temperature return to normal of 1-6 group is (54.0?28.4) hours, (48.9?27.8) hours, (49.9?23.9) hours, (58.6?33.7) hours, (52.5?25.2) hours, (63.1?51.1) hours respectively. It was longer in cefazolin group than the others. There were less puerperal morbidity and side effects of Mezlocillin. Conclusions Penicillin and Ampicillin are still the most common choices as prophylatic antibiotic in cesarean section. Mezlocillin is appropriate as well.

Objective To prepare ?-CD(?-cyclodextrin) inclusion compounds and PEG- 4000[poly-(ethylene glycol) 4000] solid dispersions of mefenamic acid (MFA)in order to improve its dissolution. Methods The inclusion compounds of MFA were prepared using saturated ?-CD solution method by orthogonal test. The solid dispersions were prepared using melt-cool process with PEG- 4000 as a carrier. The inclusion compounds and solid dispersions were identified by differential scanning calorimetry (DSC) gram and their dissolution rates were tested in pH8.0 buffer solution. Results The suitable condition for preparing ?-CD inclusion compounds of MFA industrially was the weight ratio of 1∶4 between MFA and ?-CD, agitating for 4 h at 70 ℃. The suitable proportion for preparing solid dispersions of MFA was the weight ratio of 1∶4 between MFA and PEG- 4000. Conclusion Dissolution rates of MFA are apparently improved in inclusion compounds and PEG- 4000 solid dispersions, and the solubility of MFA is apparently increased by 2～3 times in inclusion compounds and PEG- 4000 solid dispersions.

The related literatures were reviewed.Results Among 7 cases of hydatial cysts, multiple cyst in one, singular cyst in 6, one of them was rupture caused by trauma. Mammography showed a circluar or elliptical dense shadow, the density was homogeneous with well defined margen, measured 4～8 cm in maximum diameter, 3 cases appeared typical shell-like calcification.Conclusion In combination with clinical and endemical data, molybdenum target mammography can be used in diagnosing hydatid cyst of the breast.

Objective To compare the effectiveness of propafenone,(intravenous and oral) and lanatoside C in reversing atrial fibrillation (AF) and their safety in non-rheumatic patients.Methods Ninety-seven recent onset(≥0 5h～41days) AF patients were included. Subjects with valvular heart disease, heart failure (NYHA heart function≥Ⅲ degree),myocardial infarction, sick sinus syndrome, atrioventricular block(≥Ⅱ degree), preexcitation syndrome and hyperthyroidism were excluded. Three groups were subdivided according to the results:⑴ The group of intravenous propafenone(groupⅠ):thirty-three patients were given intravenous injection propafenone 70 mg within 7 minutes, the non-converted patients were given another 140 mg (0 5～1mg/min) intravenous infusion. ⑵The group of oral loading dose propafenone: Thirty-two patients were given propafenone 450 mg orally(groupⅡ).⑶The group of intravenous lanatoside C(groupⅢ):Thirty-two patients were given intravenous lanatoside C 0 4 mg within five minutes and another 0 2 mg must be added to if AF was not reversed in 4 hours. EKG, blood pressure, symptoms, AF reversing and ventricular rate were closely observed under heart monitoring all patients. The time from intravenous injection or receiving the drug to reversing the AF to sinus rhythm was recorded. Observing the reversal rate and time of the three groups of patients for 30 minutes,1h, 2h, 4h, 8h respectively, we could get the results as follows.Results Average reversal time is: group Ⅰ (0 8?0 4)h, group Ⅱ(4 1?1 8)h. group Ⅲ(3 7?2 0)h, There was a prominent difference (P0 05).Conclusion Of the above three methods in reversing AF, the average reversal time of intravenous propafenone is the shortest, and the have the most efficient reversal rate.

To study the current situation of Chinese medicine services from both perspective of supply and demand, looking to promote the healthy development of Chinese medicine community health service strategy. Questionnaire survey was conducted to practitioners of 14 community health service centers in Longhua district (80) and service objects (800). Ratios and SWOT methods were used for analysis. 75 qualified practitioners and 736 qualified service objects questionnaire recoveries showed that there are different degrees of commands from both sides, different options on therapeutic methods and lack of practitioners. It is suggested that community health service center should supply TCM service according to different time, different place and different patient on different type and levels.

Objective To investigate the clinical efficacy of new-type patent endotracheal tube in difficult endotrachea intubation patients.Methods Seventy-three patients with the abnormal airways were selected as our subjects.Patients were given the traditional endotracheal tube by mouth after anesthesia.The successes patients in terms of endotracheal intubation were as group Ⅰ (n =73).The failed patients were asgroup Ⅱ (n =63),who performed the secondary endotracheal intubation with new type patent endotracheal tube.Analyze the success rate of intubation of the two groups when on use the tube core.Results The first time intubation success rate and intubation success rate was (2.7％ (2/73),13.7％ (10/73) respectively) in Ⅰ group,and 73.02％ (46/63) and 98.41％ (62/63) respectively in the group Ⅱ,and there was the significant difference between two groups (x2 =36.01,31.08 respectively,P ＜ 0.01).Conclusion The new type endotracheal tube was proved with three advamage of good plasticity,without need of auxiliary core intubation with trachealtube and give full play to lead the soft cannula guide tubes leading role.Therefore,the new type patent endotracheal tube has more efficacy over traditional tube.
