OBJECTIVE:To promote rational drug use in the clinic. METHODS: By reviewing the pertinent literature both at home and abroad, the causes of ADRs induced by Chinese medicine injections were analyzed. RESULTS: the reasons accountable for ADRs induced by Chinese medicine injections were as follows: the active ingredients in the Chinese herbal medicine; poor stability of preparation and the unreasonable preparation process; failing to follow indications in the treatment, drug incompatibility, improper dosage, improper administration and individual differences. CONCLUSION: It is necessary to strengthen monitoring in clinical application of Chinese medicine injections. Only through strictly following indications, probing into allergy history before drug use, making sure the quality of the injection is qualified, paying special attention to drug compatibility can the ADRs be greatly reduced or avoided.

Objective To manage calcaneal fractures with an U-shaped external fixator combined with close manipulative reduction. Methods From February 1997 to November 2002, 31 patients with 34 calcaneal fractures were treated with self-designed U-shaped external fixator combined with close manipulative reduction. All patients were males aging from 7 to 50 years with an average of 32 years. The external fixation device consisted of two partial rings, three modular connecting rods and several pins. According to Essex-Lopresti classification, there were 10 extra-articular fractures without involving the subtalar joint, and 24 intra-articular fractures involving the subtalar joint. Two upper pins were inserted in cross through the distal tibia, and one of two lower pins was inserted laterally through the anterior part of calcaneus, the other was posterior into the calcaneous tuberosity or larger fragment connecting with Achilles tendon. After the manipulative reduction, the frames were applied. Results 31 calcaneal fractures were found with satisfactory reductions after manipulation. The widths of the heels were restored in certain extent; the heights of foot arch and calcaneus were resumed to normal; the B hler angle increased from 15? to 40? (mean, 25?). The duration of hospitalization was on an average of 7 days. The duration of external fixation was averagely 8 weeks. All patients were followed up with a mean period of 8 months (range, 6 to 12 months). All of the fractures healed well. No nonunion, delayed healing of bone or other complications was found. All patients resumed to walk on foot after 2 to 4.5 months. According to Fernandez scoring system, results were graded as excellent and good in 31(91%). Conclusion Using U-shaped external fixator combined with close manipulative reduction is a satisfying technique to treat calcaneal fractures. By ankle joint spanned traction and fixation, this technique overcomes displacement of fragments caused by contracture of tendo calcaneus, maintains width of heel and biodynamic anatomy of foot, avoids complications of wound caused by open reduction and internal fixation.

Objective To study the operative methods and surgical technique of arthroscopical meniscal suture in treatment of meniscal tears under local anesthesia. Methods From February 1999 to November 2003, we cure 32 patients (22 males and 10 females) with this method. The patients' average age is 29. Results All of the patients accept the operation through arthroscopy under local anesthesia. The procedure last 50 minutes on an average. 92% of the patients gain good results, no severe complications. Conclusion This method has the advantages of less pain, time saving(save time), quick recovery and less complications.

Objective To analyze the clinical significance and echocardiographic feature of myocardial bridging. Methods and Results Among 3?216 patients who underwent coronary angiography, 47 patients had myocardial bridging were analyzed, of whom 13 patients had complicated coronary atherosclerosis, 1 had with aortic stenosis and 3 had hypertrophic myopathy. The prevalence of myocardial ischemia was about 40% in the 30 patients with isolated myocardial bridging. Compared with patients with no ischemia. The patients with ischemia had more severe systolic stenosis[(67.58?15.35)% vs (49.89?21.83)%], bigger LVM [(215.57?42.21)g vs (178.73?51.04)g] and E/A

Objective In order to explore pathogenesis about inflammation injury of the hematoma peripheral zone after cerebral hemorrhage. Methods 48 adult male wistar rats are randomly divided into intracerebral hemorrhage (ICH) groupand control group. After 3 h, 24 h,72 h and 7 d of ICH, intercellular adhesion molecule-1 (ICAM-1)was detected by immunohistochemical SABC staining in rats brain slice. Positive cells expression of the ICAM-1 were measured by color image analysis system。Brain edema were assayed by dry-wet weight method. Results The expression of ICAM-1 increased at 3 h ( P 0.05) compared to contral group. Conclusions The overexpression of ICAM-1 may play important role in the perihematoma edema formation and ischemic injury.

Objective To evaluate the feasibility and efficacy of optical coherence tomography (OCT) in interventional diagnosis and treatment of borderline coronary artery disease. Methods Sixteen 40%-70% angiographically stenotic lesions from 15 patients were enrolled in the current study. Intravascular OCT was applied to each lesion after informed consent was obtained to evaluate stenosis percentage, size of lipid core, thickness of fibrous cap, existence of plaque rupture, and presence of thrombosis or calcification. Therapeutic strategies were made according to OCT outcomes as well as clinical symptoms and electrocardiographic changes. Stent coverage, apposition, and tissue prolapse between stent struts were determined in the patients undertaken percutaneous coronary intervention(PCI). Results Qualitative OCT images were obtained in 14 lesions. Ten lesions were greater than 50% stenosis, with large lipid core and fibrous cap thinner than 65 ?m, and plaque ruptures were noted in 2 of the lesions. PCI were performed in these 10 lesions. Two lesions underwent predilatation and significant intima tearings and dissections were detected with OCT. Repeated OCT after stent implantation showed complete coverage in all 10 lesions. Focal incomplete apposition were noted in 2 lesions. Significant tissue prolapse occurred in 3 lesions and segmental incomplete deployment of stent in 2 lesions. The remaining 4 lesions had small lipid cores, thick fibrous caps but with no plaque ruptures, thus PCI was not performed. Conclusion Intracoronary OCT is an effective tool to determine features of coronary lesions. It plays an important role in diagnosis of vulnerable lesions, strategy-making in treating borderline coronary artery disease and evaluation of immediate result of PCI.

Objective To determine if thiopental, propofol and ketamine can be safely used for induction of anesthesia in patients with congenital heart disease complicated by pulmonary hypertension. Methods Eighteen patients with congenital heart disease complicated by pulmonary hypertension were studied. Age ranged from 14 to 31 yr and body weight from 35 to 57 kg. The patients were premedicated with intramuscular pethidine 1 mg? kg-1 and scopolamine 0.3 mg. Swan-Ganz catheter was inserted through internal jugular vein. The patients were randomized to receive thiopental 2 mg?kg-1 , propofol 1 mg?kg-1 or ketamine 1 mg?kg-1 administered slowly via Swan-Ganz catheter for induction of anesthesia. MAP, high arterial pressure (RPA), mean pulmonary arterial pressure (MPAP), pulmonary arterial wedge pressure (PAWP), cardiac output (CO) and pulmonary vascular resistance (PVR) were measured before induction of the intravenous anesthetics. Results PVR unchanged significantly after ketamine , thiopental and propofol as compared with the baseline value. MAP was significantly decreased after injection of thiopental and propofol. Conclusion Thiopental, propofol and ketamine can be safely used for induction of anesthesia in patients with congenital heart disease complicated by pulmonary hypertension.

0.05). Significant differences of post-operative VA, time of retinal detachment, and neurepithelial thickness were found (P0.05). Conclusions The time of retinal detachment and post-operative VA in patients with retinal detachment relate to the neurepithelial thickness detected by OCT. When the duration of retinal detachment becomes longer, the macular neurepithelium becomes thicker, the histomorphological changes increase, and the post-operative VA decreases.
