OBJECTIVETo explore clinical effects of drilling decompression for femoral head necrosis at collapse stage.

METHODSTotally 22 patients with femoral head necrosis on both side were analyzed from March 2006 to February 2009. Among them, there were 20 males and 2 females aged from 24 to 52 years old with an average of 38.4 years old. All patients were Ficat I on one side and Ficat I or II on another side. Drilling decompression were performed on all patients. The average followed-up period was 5.4 years (ranged, 1 to 8 years). The endpoint of severe pain(VAS ≥7), severe dysfunction (Harris ≤ 70), radiographic progression on Ficat IV and total hip arhtroplasty (THA) was used for survivorship analysis.

RESULTSSevere pain as an endpoint,13 cases were survived on Ficat III and 18 cases on Ficat I or II (P>0.05). Severe dysfunction as an endpoint, 6 cases were survived on Ficat III and 18 on Ficat I or II (P<0.05). Radiographic progression on Ficat IV as an endpoint, 2 cases were survived on Ficat III and 18 on Ficat I or II (P<0.05). THA as an endpoint, 13 cases were survived on Ficat I and 18 cases on Ficat I or II (P>0.05).

CONCLUSIONFemoral head necrosis with Ficat III treated with drilling decompression could prolong progression of disease , decrease percentage of THA.

To study the effects of alkaloids from Coptidis Rhizoma on low-density lipoprotein receptor (LDLR) mRNA expression and antihyperlipedemic levels. The LDLR mRNA expression were detected by real time fluorescence quantitative PCR, and the levels of total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL-c) and high-density lipoprotein cholesterol (HDL-c) in serum were measured at the first and last examination. The results show that, after the drug treatment, compared with the model group, each drug group showed a lipid-lowering effect. Especially, coptisine, palmatine, jatrorrhinze were significantly reduced TC, TG, LDL-c (P < 0.05, P < 0.01), and increased HDL-c (P < 0.01). In addition, they also increased mRNA expression of the LDLR in liver and HepG2 cells. The results showed that alkaloids from Coptidis Rhizoma can regulate lipid metabolism disorder, and coptisine have the best lipid-lowering effect.

OBJECTIVETo explore the effect of Yixintai Granule (YG) on mRNA and protein expression levels of AQP2 in renal medulla of chronic heart failure (CHF) rabbits.

METHODSCHF rat model was established by ear marginal vein injection of adriamycin. Successfully modeled rabbits were divided into the model group, the high (8.4 g/kg), middle (4.2 g/kg), and low dose (2.1 g/kg) YG group, and the Furosemide group (2 mg/kg). Besides, a normal control group was set up. Equal volume of physiological saline was administered to rabbits of the model group and the normal control group by gastrogavage. YG at different doses was administered to rabbits of the 3 YG groups by gastrogavage. The intervention lasted for 4 weeks, once per day. After treatment the urine volume and pathomorphological changes of renal medulla tissue were observed. mRNA and its protein expression levels of AQP2 were detected.

RESULTSCompared with the normal control group, the urine volume decreased significantly, mRNA and protein expression levels of renal medulla AQP2 increased significantly in the model group (all P < 0.01). Compared with the model group, the urine volume increased significantly, and mRNA and protein expression levels of renal medulla AQP2 decreased significantly in all medicated groups (all P < 0.01). Compared with the low dose YG group, the urine volume significantly increased and the mRNA expression level of renal medulla AQP2 significantly decreased in the middle and high dose YG groups (all P < 0.01). The expression level of AQP2 protein significantly decreased in the high dose YG group (P < 0.01). Pathological changes of the renal medulla was the most obviously seen in the model group. But they were alleviated to various degrees in all medicated groups. They were more obviously attenuated in the middle and high dose YG groups.

CONCLUSIONYG could improve CHF possibly through down-regulating mRNA and protein expression levels of AQP2 in renal medulla, and elevating the urine volume.

Objective To investigate the angiographic manifestation of the proper esophageal artery (PEA),the hish risk factom for the presence of the anomalous PEA in hemoptysis and to evaluate the safety of transcatheter aaefial embolization(TAE) of the PEA using gelatin sponge(GS).Methods Selective esophageal arteriography WSS performed in forty-three patients with hemoptysis,including 15 cases of pulmonary tuberculosis,18 cases of bmnchiectasis,7 cases of posttuberculous bronchiectasis and three cases of lung cancer. One case experienced failure of bronchial arterial embolization. The angiographic manifestation of the PEAs Was studied.The complications of the procedure and clinical results were observed in the patients who underwent TAE using GS.Results Thirty-nine PEAs were catheterized selectively in 37 patients(86.0%).Eighteen anomalous PEAs(46.2%)were catheterized selectively in 17 patients (45.9%).The anomalous PEAs showed tortuosity,dilatation,hyperplasia,shunting with pulmonary artery and anastomosis with the bronchial artery.All lesions involved basal segment of inferior pulmonary lobar. Bronchiectasis Was the most frequent disease for PEA abnormality. No complications occurred and satisfactory curative effect Was achieved with TAE of the anomalous PEAs.Conclusions It is necessary to perform selective proper esophageal arteriography when the lesion involves basal segment of inferior pulmonary lobar in hemoptysis.Supplemental TAE of the anomalous PEA using GS is safe and valuable in the management of hemoptysis.

OBJECTIVETo investigate therapeutic strategy on septic arthritis after arthroscopic anterior cruciate ligament reconstruction.

METHODSThe clinical data of 6 cases of septic arthritis after arthroscopic anterior cruciate ligament reconstruction in our department from March 2005 to February 2014 were analyzed. All the patients were male,ranging in age from 18 to 36 years old. After operation, the knee joint became painful and swollen, and ESR and CRP were both increased. Culture of joint fluid allowed the recovery of staphylococcus epidermidis. The patients were dealt with arthroscopic debridement and infusion-drainage. The clinical results were evaluated by Lysholm rating system and range of motion.

RESULTSThe infection of all the patients was controlled. The ESR and CRP both recovered to normal level. The score of Lysholm rating system ranged from 85 to 95,and the range of motion was 120 to 135 degree.

CONCLUSIONArthroscopic debridement combined with infusion-drainage is effective in septic arthritis after arthroscopic anterior cruciate ligament reconstruction.

OBJECTIVETo study the characteristics of autopsies in medical dispute cases, with respect to class of hospitals, clinical units concerned, age of deceased and cause of death.

METHODSTwo hundred and seventy-five autopsies performed on medical dispute cases during the period from January 1, 2002 to September 30, 2008 at the Department of Pathology, Health Science Center, Peking University, China were retrospectively reviewed.

RESULTSDuring the period of study, the number of autopsies performed on medical dispute cases gradually increased. Medical dispute cases happened more often in surgical, obstetric and gynecology departments of grade II and III hospitals, as well as emergency departments of grade I hospitals. Perinatal death in infants of less than 1 year old more frequently caused medical dispute than death occurring in other age groups. According to the International Classification of Diseases (ICD10), disorders of the circulatory system, perinatal illnesses, external injury or iatrogenic conditions represented the major categories of cause of death. In general, the vast majority was due to natural causes and only 13.5% were related to iatrogenic reasons or medical negligence. Pathologic diagnosis of sudden coronary death, myocardial infarction and viral myocarditis should only be made with strict diagnostic criteria.

CONCLUSIONSAutopsies for medical dispute cases can help to delineate the cause of death and provide evidence for further clarification. Meticulous autopsy techniques, application of strict diagnostic criteria and detailed analysis of cause of death are key steps in achieving a high quality service in this area.
