OBJECTIVE:To provide reference for the instructions of domestic Clindamycin phosphate injection. METHODS:The contents in the instructions of domestic Clindamycin phosphate injection approved the listing from Jan. 2006 to Dec. 2015 were statistically investigated according to Regulation for Drug Package Inserts and Label Management and Regulatory Guidelines for Chemicals and Biologicals,and the items with great differences in different approval number were analyzed comparatively. RE-SULTS:The labeling rate of clinical experiment in the collected 25 instructions of domestic Clindamycin phosphate injection was 0,the labeling rate of validity was 44%,the labeling rate of use for elderly patients was 68%,the labeling rate of overdosage was 76%,and the labeling rate of others was 100%. The items with great differences were mainly special populations,usage and dos-age,adverse reactions,validity,storage conditions and precautions. CONCLUSIONS:There are great differences in instructions of domestic Clindamycin phosphate injection,some items are inaccurate,incomplete and lack of scientificity,which may result in ir-rational drug use in patients and increase the risk of medication. It is suggested that the domestic enterprises should modify and per-fect the contents of the instructions of domestic Clindamycin phosphate injections referring to the instructions of foreign brand name drug;and the drug regulatory department should strengthen the monitoring of drug instructions.

OBJECTIVE: To analyze the general and forensic pathological characteristics of death due to fat embolism syndrome (FES) and to provide reference data for forensic identification. METHODS: Twenty autopsy cases due to FES were selected from the forensic center of a medical college from 1999 to 2012. The general and forensic pathological characteristics such as the ways and types of injuries, clinical manifestation and the pathological changes were summarized. RESULTS: Fat embolism mainly occurred after long bone fracture or a large area of soft tissue injury with the majority of cases being fat embolism of lung and occasional cases being combined embolisms of lung and brain as well. The onset of symptoms appeared shortly after the injury or surgery. Lipid droplets could be observed within small pulmonary vessels and verified by special staining. CONCLUSION There are particular characteristics in death due to FES in concern with types of injuries, onset of symptoms and pathological findings. In order to find out the direct evidence of FES, special staining (oil red O staining) can be used in the forensic identification.

Objective To compare the effect of diversification rehabilitation team mode on function in patients with cerebral infarction. Methods Sixty-six patients with cerebral infarction were divided into diversification rehabilitation team mode group (diversification group) and routine rehabilitation mode (routine group) according to the rehabililation method with 33 cases each. All patients of 2 groups were treated for 2 weeks. Evaluations were made before and after treatment. The simplified Fugl-Meyer motor function rating scale was used to evaluate motor function, modified Barthel index was used to evaluate activities of daily living, and MOS 36-item short form health survey was used to evaluate quality of life;and 0-100 digital simulation assessment was used to evaluate patient satisfaction after treatment. Results The simplified Fugl-Meyer motor function rating scale score, modified Barthel index score, MOS 36-item short form health survey score and patient satisfaction rate after treatment in diversification group were significantly better than those in routine group: (76 ± 4) scores vs. (63 ± 3) scores, (65 ± 3) scores vs. (52 ± 4 ) scores, (57 ± 7) scores vs. (44 ± 6) scores, (92 ± 5) scores vs. (77 ± 3) scores, and there were statistical differences (P<0.05). Conclusions Both kinds of rehabilitation model can promote functional recovery in patients with cerebral infarction, but diversification rehabilitation team model is better than conventional model.

Objective To investigate the efficacy and safety of citrate anticoagulation for continuous renal placement therapy (CRRT) in patients at high risk of bleeding. Methods Forty-seven patients who needed to CRRT and were admitted into the department of critical care medicine from January 2015 to October 2016 were enrolled in this study. According to the patient′s actual condition, they were divided into citrate groups (24 cases) and saline group (23 cases). Patients in saline group were given saline wash. The efficacy and safety were compared between the two groups. The filter lifetime, after treatment the activated partial thromboplastin time (APTT), hemoglobin (Hb), blood gas indexes were compared between the two groups. Results The citrate group used 76 filters while the 0.9% sodium chloride group used 87 filters. The average filter lifetime in citrate group was (22.4 ± 12.7) h which was longer than (8.6±3.3) h in 0.9%sodium chloride group (t=9.79, P<0.01). The incidence of coagulation in extracorporeal circulation was 3.9%(3/76) which was lower than 16.1%(14/87) in 0.9%sodium chloride group(χ2=5.20, P<0.05). Conclusions Regional citrate anticoagulation is a safe and effective option for CRRT in patients at high risk of bleeding.

OBJECTIVETo investigate occupational health status of female workers in pharmaceutical industries and to propose the protective measures for the occupational health.

METHODA total of 2816 female workers from 19 pharmaceutical industries in Shandong and Gansu provinces were investigated by a questionnaire.

RESULTS73.1% of female workers exposed to occupational hazards, mainly to toxic chemicals. 63.2% of them suffered from dysmenorrhea; 38.5% of them have reproductive system diseases, i.e. mammary gland hyperplasia (44.1%), cervical erosion (26.5%), uterine annex inflammation (24.2%); 17.1% of them suffered from accidental work injuries; 34.7% of them complained about low back pain, and 29.7% of them perceived hearing loss. 94.9% of female workers hoped to get the occupational health and labor protection knowledge and skills.

CONCLUSIONStrengthening the supervision of labor protection for female workers, including technical measures occupational hazards control and health-related knowledge, and improving the occupational health status of female workers should be conducted.

Thrombolysis with intravenous tissue plasminogen activator (t-PA) is currently an approved therapy for patients with acute ischemic stroke. Acute myocardial infarction (AMI) immediately following t-PA treatment for stroke is a rare but serious complication. A case of acute myocardial infarction (MI) following IV t-PA infusion for acute stroke was observed. This is a 52-year-old male with a known history of hypertension and chest pain, who subsequently developed MI four hours after IV t-PA was administered for acute ischemic stroke. The disruption of intra-cardiac thrombus and subsequent embolization to the coronary arteries may be an important mechanism. In addition, spontaneous recanalization of infarct-related arteries may be associated with greater myocardial salvage and better prognosis.

OBJECTIVETo investigate the expression of mammary serine proteinase inhibitor(Maspin) in patients with oral squamous cell carcinoma and its relationship with clinicopathological features.

METHODSThe Maspin protein expression was examined in 45 patients with oral squamous cell carcinoma and in non-malignant oral epithelia by immunohistochemical staining. The relationship between the Maspin protein expression and the clinicopathological parameters was statistically analyzed.

RESULTSThe Maspin protein expression in the cancerous tissues of oral squamous cell carcinoma was lower than that in the non-malignant oral epithelia (P = 0.001). Negative correlation was found between the Maspin protein expression in cancerous tissue and the status of lymph node metastasis (P = 0.038). Positive Maspin protein expression indicated negative lymph node metastasis, and negative correlation was also found between the Maspin protein expression and the postoperative metastasis (P = 0.004). Positive correlation was found between the Maspin expression and the patients' survival rate (P = 0.014), patients with positive Maspin protein expression having higher survival rate than those with negative Maspin expression.

CONCLUSIONSMaspin might be useful as a potential prognostic marker for oral squamous cell carcinoma.

Objective:To explore the effects of myosteatosis and blood glucose (BG) on postoperative complications in non-diabetic gastric cancer patients receiving supplemental parenteral nutrition (SPN) after gastrectomy.Methods:Patients who underwent radical gastrectomy between March 2017 and June 2021 in the Department of Surgical Oncology, the First Hospital of Lanzhou University were included in this study. Various preoperative inflammatory and nutritional indicators, including skeletal muscle metrics at the third lumbar level on CT, were collected retrospectively. Postoperative BG within 3 days and complications within 30 days were monitored. Patients were divided into two groups according to the presence or absence of myosteatosis (assessed via skeletal muscle density [SMD]) and the differences in postoperative BG and complication incidence were compared. Mediation model was used to analyze the mediating effect of BG in the association between SMD and postoperative complications.Results:A total of 357 patients were included in the study. Compared with the 299(83.8%) patients without myosteatosis , the incidence of hyperglycemia, mean BG, maximal BG, and BG fluctuation while on SPN in the 58(16.2%) patients with myosteatosis were higher, and the comprehensive complication index (CCI) and the incidence of complication were higher ( P<0.05). More importantly, BG showed the mediation effect of -0.0892 in the effect of SMD on CCI ( P<0.05), with the effect size of 19.3％. Conclusion:Myosteatosis and postoperative hyperglycemia are associated with higher incidence of complications, and BG plays an intermediary role in the association between myosteatosis and CCI.

OBJECTIVETo prepare the PrP specific monoclonal antibodies (mAbs) that can be used for the detection of mammalian prions and study of pathogenesis of prion diseases.

METHODSSeveral BALB/c mice were immunized with recombinant hamster prion protein (HaPrP). Three hybridoma cell lines designated as B7, B9, and B10, secreting monoclonal antibodies against HaPrP, were established by hybridoma technique. The mAbs reactivities were evaluated with ELISA, Western blot, and immunohistochemistry.

RESULTSThe mAbs produced by these cell lines reacted well with different recombinant hamster PrP proteins. Western blot analyses showed that mAbs B7 and B9 reacted with PrPSc from the scrapie-infected animals after proteinase K digestion with three glycosylated forms. The mAbs exhibited cross-reactivity with various PrPC from several other mammalian species, including humans and cattles. Immunohistochemistry assays confirmed that mAbs B7 and B9 could recognize not only extracellular but also intracellular PrPsSc.

CONCLUSIONThe mAbs of prion protein are successfully generated by hybridoma technique and can be applied for the diagnosis of prion associated diseases.
