The side effects of cesarean with the increasing rate section began to attract the attention of pediatricians in recent years. Previous studies reported that the incidence of neonatal pnermothorax by full-term cesarean section, especially selective cesarean section, was significantly higher than vaginal birth or non-selective cesarean section. In addition, with an extensive establishment of NICUs in China and widely use of mechanical ventilation, the rate of successful neonatal rescue was improved obviously, but the incidence of pneumothorax was increasing. Studies suggested that the incidence of neonatal iatrogenic pneumothorax was highly relevant with selective cesarean section and mechanical ventilation. The indications for cesarean section and mechanical ventilation should be carefully considered.

OBJECTIVE: To evaluate the value as well as correlation between blood drug level and blood routine results in patients using cyclospone A (CsA) following renal transplantation via analyzing varies of immunosuppressive agents used in renal transplantation. METHODS: Retrieval-related contents were collected by computer from Chinese Journal Full-Text Database with of "renal transplantation, CsA, and therapeutic drug monitoring". Simultaneously, data of patients who received CsA treatment after renal transplantation in the Department of Laboratory, Liaoning Provincial Electrical Hospital were selected. All the literature was retried and analyzed. RESULTS: A total of 717 patients were included in the final analysis. It demonstrated that 6 sorts of immunosuppressive agents, such as mizoribine, sirolimus, zenapax, mycophenolate, and basiliximab play an important role in immune suppression after organ transplantation. However, there still exist problems need to be further explored. CsA was more suitable for clinical application with lower price and good curative effect, which worked better combined with other immunosuppressive agents. CONCLUSION: A best curative effect of CsA can be achieved by timely adjusting therapeutic regimen under the patient's condition. Meantime, a high efficiency and low toxicity drug with specific tolerance is the ultimate goal of immunosuppressive agents.

Objective: To prepare voriconazole long-circulation liposomes and evaluate the characteristics of pharmacokinetics in rats.Methods: Voriconazole long-circulation liposomes were prepared by a thin film dispersion extrusion method.The drug release of voriconazole from the long-circulation liposomes was investigated in phosphate buffer solution (PBS) and in rat plasma.The physicochemical properties of the long-circulation liposomes before and after the freeze-drying were studied, such as the particle diameter and the particle shape.The concentration of voriconazole in plasma was determined after tail-vein injection of the long-circulation liposomes in rats.Results: The mean particle size of voriconazole long-circulation liposomes was (192.1±49.3)nm with homogeneous small spherical morphology as seen under a transmission electron microscope.Voriconazole was released in a sustained manner in PBS while much faster in plasma from the long-circulation liposomes.The t1/2 and AUC0-t of the long-circulation liposomes was respectively 2.17 and 2.31 times higher than that of voriconazole injection.Conclusion: Long-circulation liposomes prolong the circulation time and increase the bioavailability of voriconazole.

Trauma has been one of the public haza rds in the modern society.About 1/2t o 2/3of modern traumas involve the musculoskeletal system.The priority in an em ergency care of a severely injuried p a-tient is to save his life and preserve major functions of his body as much as possible.To minimize the rate of mortality or disability,it is of prime importance to start timely emergency resuscitation process,control of life -threatening conditions(such as hypovolemic shock),hemostasis,adequate ventilation,restoring normal perfu-sion,and prompt diagnosis and skill ful evaluation of the general and local significant risks so as to adopt fu rther interventions,especially for multiply injured patients.After satisfactory recovery of vital signs and stable main-tenance of adequate perfusion press ure,surgical procedures,such as debridement,fracture fixation,repair of soft tissue and management of associated lesions are advisable at an early sta ge.[

OBJECTIVE: To explore the materials and selection of esophageal stents, and to discuss the application of covered stants in treating esophageal malignant stenosis.METHODS: CNKI and Medline databases were retrieved by computer for papers published from 1980 to 2009 with search terms of "esophageal carcinoma, esophageal stenosis, esophageal stent, and fabric-covered metallic stent". The language was limited for Chinese and English. A total of 61 iteratures were initial searched by computer, according to inclusive and exclusive criteria, 29 literatures were selected by the first author. Problems including esophageal stent category, material selection, as well as application of covered stents in treating esophageal malignant stenosis were reviewed and summarized.RESULTS: Totally 29 literatures were included in this paper. No concealed allocation or blinding method was described in the literatures. According to preparing materials, the stents could be divided into stainless metal stent, memory metallic stent and polyester plastic stent. As tissue-engineered materials, stents could be assigned into biodegradable polymer matrix stent and non-degradable biodegradable polymers stent. Each material stent possesses distinct advantage and disadvantage. The covered stents could relief esophageal stenosis effectively, interrupt tumor growth, and prevent restenosis. CONCLUSION: As a palliative therapy for treating esophageal malignant stenosis, covered stents can elevate patients' life quality and prolong survival times.
