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 detect the expression of MSI2 protein and mRNA in pancreatic ductal adenocarcinoma (PDAC) tissue,and investigate the correlation between the expression of MSI2 protein and the clinicopathological parameters.Methods The expression of MSI2 protein in 61 PDAC specimens and paired adjacent non-cancerous pancreatic tissues were detected by immunohistochemistry.Western blot and quantitative real-time PCR (QRT-PCR) were used to examine the expression of MSI2 protein and mRNA level in 10 PDAC specimens and adjacent non-cancerous pancreatic tissues.Then the relationship between MSI2 expression in cancerous tissues and clinicopathological parameters was analyzed.Results In 61 patients with PDAC,the expression rate of MSI2 protein was higher in cancerous tissues (63.9％) compared with that in paired non-cancerous pancreatic tissues (41.0％),and the difference between the two groups was statistically significant (t =2.809,P =0.007).The expression levels of MSI2 protein in 10 fresh PDAC specimens and adjacent non-cancerous pancreatic tissues were 0.748 ± 0.195 and 0.420 ± 0.171,and the expression level of MSI2 mRNA in PDAC specimens was as 2.507 ± 2.981 times as much of adjacent non-cancerous pancreatic tissues,and the difference between the two groups was statistically significant (t =3.689,P=0.005;t =2.660,P =0.026).The expression of MSI2 in cancerous tissues was only positively associated with the size of the tumor (x2 =5.096,P =0.024),but it was not associated with other parameters.The median survival of patients with high MSI2 expression was 321 d,and it was 730 d for patients with low MSI2 expression,and the median survival of patients with high MSI2 expression was significantly shorter than that of low MSI2 expression (x2 =6.706,P =0.010).Conclusions The expression MSI2 is up-regulated in PDAC and related to the tumor size.The patients with high expression of MSI2 protein have poor prognosis.

The regional blood flow measurement (RBFM)of lenghtened limb with a peripheral circulation mesuremnt system was carried ou t in 20 rabbits after their tibia was lengthened in different lengthening rates.It was found that whenever a limb was lengthened with a rate over 1 mm/day,the RBFM of the lengthened limb decreased rapidly and returned to preoperative level 8 hours later.It is believed that the vascular and muscular tissues of a limb possess good adaptive capcity to the lengthening rate of 1 mm/day,When the lengthening rate exceeds 1 mm/day,it is liable to result in a significant re-duct of regional blood flow,and then atrophy and weakening of the muscles will occur.

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 strengthen the inspection for qualification of new drugs when introduced in order to guarantee the quality of new drugs and the safety of drug use.METHODS:The problems existing in the inspection for qualification of new drugs were exemplified and classified.RESULTS&CONCLUSION:There existed the problems in the respect of validity,authenticity,effectiveness,and integrality.The good maintainance of the database of SFDA plays a important role in in-specting the new drugs when introduced,while on the other hand such issues as establishment and use of credibility file in medical agencies are worth discussing.

OBJECTIVE:To facilitate the in-depth implementation of Prescription Administrative Policy("New Method" in short).METHODS:The change of the Prescription Administrative Policy and its problems were analyzed through comparison between the "New Method" and the trial edition.RESULTS & CONCLUSIONS:Improvements of Prescription Administrative Policy such as the introduction of prescription comment system,clarifying supervising subjects and strengthening requirement on prescription dispensing rights etc play a role in tightening comprehensive management on prescriptions and promoting rational drug use.However,the defects of Prescription Administrative Policy such as the absence of the regulations unsuitable for medical orders in retail pharmacy and endemic areas and the unidentified prescription forms need to be improved step by step in the practice.

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.

Application of virtual experiment in the pathophysiology experimental teaching brings more vividness and interest,increases students'activities to complete experiments just like being in a real laboratory.it also relieves the contradiction between teaching requirements and experimental conditions effectiveIy,and take a new learning style to students and promote the changes of teachers'teaching model and teaching idea.

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.
