Objective To analyze the clinical and CT manifestations of the chest and abdomen lymphangioleiomyomatosis (LAM). Methods The clinical and CT manifestations of 13 patients with LAM proved histopathologically were reviewed retrospectively.Results Twelve patients onset with intrapulmonary manifestations all had progressive dyspnea, other symptoms included pneumothorax of recurrent attacks, chest distress, hemoptysis, cough, chylothorax and so on. During the course of disease, 12 patients had no extrapulmonary symptoms, abdominal great goiter was found unintentionally in the rest one without any intrapulmonary symptoms. Pectoral CT manifestations included sporadic or asystematic cysts in pulmones with size of 2-20 mm, and most had thin and clear capsule wall. The lung parenchyma among cysts was mostly normal. Four patients had pneumatocele, 2 had pleural effusion. Abdominal CT was performed in 10 patients and 7 had abnormal findings: renal angiolipoleiomyoma (ALL) in 3 including one had retroperitoneal multiple lymphangiomyomas and effussion and seroperitoneum, another 2 had multiple liver ALL and spleen accretion. The rest 4 patients included retroperitoneal lymphadenectasis in 2, seroperitoneum in one, as well as retroperitoneal lump and spleen accretion in one patient.Conclusion Pectoral and abdominal symptoms in LAM are not specific, but the CT manifestations somehow specific, which are helpful to the identification and early diagnosis of LAM.

With the economic development and the deepening of reform in China,more attention has been paid on health.Based on literature from Chinese Journal of Health Statistics in 2008,the number and ranks of practicing doctors,occupancy of hospital beds,the disease spectrums,outpatient per year were analyzed.The results hold it is better for the doctors to practice in more medical institutions.

To enhance the quality and efficiency of ozagrel by investigating the differences between the ozagrel polymorphs in bioavailability. Solid ozagrel in different polymorph forms were orally administered to SD rats. An HPLC method was established to determinate plasma level of ozagrel. The bioavailabilities of two polymorph forms were calculated and compared. The pharmacokinetic parameters of ozagrel, were as follows: Cmax was 32.72 ± 17.04 and 34.01 ± 19.13 mg · L(-1), respectively; AUC0-t was 61.14 ± 14.76 and 85.56 ± 18.08 mg · L(-1) · h, respectively; t½ was 1.53 ± 0.51 and 4.73 ± 3.00 h, respectively. There was no significant difference in pharmacokinetic parameters between form I and II polymorphs of ozagrel while the t½ of form II is longer, which indicates that the use of form II polymorph as pharmaceutical product may prolong the effective action time in clinics. This would help the polymorph quality control in drug production.

Traditional medicine (TM) has been practiced in China for several thousand years. To better standardize the behaviors of medical staff of TM, rapidly improve their professional level, effectively and reasonably distribute TM resources, decrease the unnecessary application of medical care and suppress the rapidly increasing medical expenses, it is necessary to urgently set clinical therapeutic guideline in TM under the direction of evidence based medicine (EBM). The article also discusses the main existing problems and their solutions in setting clinical therapeutic guideline in TM.

Salvianolic acid A (Sal A) is one of the most effective compounds isolated from the root of Salvia miltiorrhiza. Up to now, several studies regarding the pharmacokinetic profiles of Sal A have been reported, however there is no such study reported in monkeys, the species which is more similar to human. The aim of this study is to develop a LC-MS method for the determination of Sal A in monkey plasma and apply it to the pharmacokinetic studies of monkeys. After single intravenous administration of Sal A, the plasma concentration-time curves were observed and the main pharmacokinetic parameters were calculated. The plasma concentration at 2 min (C2 (min)) values were (28.343 ± 6.426), (45.679 ± 12.301) and (113.293 ± 24.360) mg x L(-1) for Rhesus monkeys treated with Sal A at 2.5, 5 and 10 mg x kg(-1). The area under the concentration-time curve (AUC(0-∞)) values were (3.316 ± 0.871), (5.754 ± 2.150) and (13.761 ± 2.825) μg x L(-1) x h, respectively. Furthermore, this method was improved and applied to the simultaneous determination of Sal A, Sal B and Sal C, which provided useful information for preclinical studies and clinical trials of Sal A, Sal B and Sal C.

OBJECTIVETo investigate the clinical application of free superficial iliac circumflex artery skin flaps, as well as the management of donor site defects.

METHODS17 free superficial iliac circumflex artery skin flaps were applied for the traumatic defects or deformities on face, neck, foot, hand, ankle and lower leg, respectively. The donor site defects were closed directly or covered by paraumbilical island flaps.

RESULTSThe 17 flap size ranged from 5 cm x 3 cm to 19 cm x 14 cm. 16 flaps survived completely except 1 flap with partial necrosis, which was closed by free skin graft. The donor site defects were closed directly in 10 cases, and covered by paraumbilical island flaps in 7 flaps without no flap necrosis. The abdomen had a good appearance.

CONCLUSIONSGood appearance can be achieved with free superficial iliac circumflex artery skin flaps for the defects on face, neck, foot, hand, ankle and lower leg. Paraumbilical island flap can be used for the donor site defects.
