Objective Accidental public health emergencies occurred frequently all over the world in the last decade. The problem of how to set up an effective system for prevention and control of infectious diseases has aroused the attention of all the nations worldwide. The present paper discussed the contributions of the clinical laboratory in hospital during public health emergencies by collecting samples, establishing and applying a rapid diagnosis platform for infectious pathogens, ensuring laboratory biosafety, and developing a strategy in case of emergency. These countermeasures may be helpful for the army to establish an effective system and mechanism in handling public health emergencies.

Objective To reproduce the human endometriosis (EMS) in nude mouse, and to asssess the effects of endostatin in this model. Methods Endometrium tissue was collected from four women undergoing hysterectomy for EMS, and it was transplanted into 30 female BALB/c nude mice by subcutaneous injection (n=20) and intraperitoneal injection (n=10) respectively. The development of endometriotic lesions in nude mice was observed three times every week. Two weeks later, the successful rate in the two groups was estimated. The model mice in subcutaneous injection group were then randomized into treatment group (n=8) and control group (n=7). The mice in treatment group were injected with human endostatin (2mg?kg -1 ?d -1 ), while the mice in control group received an equivalent volume of PBS. All mice were sacrificed 14 days after treatment. Immunohistochemistry was used to determine the expression of vascular endothelial growth factor (VEGF). Results Transplantation was successful in 7 nude mice in abdominal implantation group and 15 nude mice in subcutaneous injection group. The success rate was 75% in subcutaneous injection group and 70% in abdominal implantation group, no significant difference was found between two groups. The level of VEGF in the nude mice treated with endostatin was significantly lower than that in the control group (P

ObjectiveTo compare the efficacy between needling peri-ocular points plus abducens oculi and needling peri-ocular points alone in treating abducens paralysis, for evaluating the effectiveness and advantage of needling peri-ocular points plus abducens oculi.MethodFollowing the random number table, 86 patients with postnatal unilateral abducens oculi were divided into two groups: 43 cases in the control group were intervened by conventional acupuncture at peri-ocular points including bilateral Taiyang (EX-HN5), Cuanzhu (BL2), Fengchi (GB20), Hegu (LI4) and Waiguan (TE5), plus Baihui (GV20), Sizhukong (TE23) and Tongziliao (GB1) on the affected side; 43 cases in the treatment group were intervened by acupuncture at peri-ocular points and abducens oculi, i.e. to puncture the abducens oculi (1~3 mm behind the attached point of the extrarectus to eyeball) in addition to the treatment given to the control group. After 3 treatment courses, the total effective rate, average recovery time and improvement of strabismus angle were observed.ResultThe total effective rate was 93.0% in the treatment group, significantly higher than 81.4%in the control group (P<0.05); of the 28 cured patients in the treatment group, the average recovery time was (34.51±7.91)d, versus (41.88±7.87)d in the 22cured patients in the control group, and the difference was statistically significant (P<0.01). There was a significant difference in comparing the improvement of strabismus angle between the two groups (P<0.01); after treatment, the strabismus angle was (11.23±6.32)° in the treatment group versus (14.14±6.85)° in the control group, and the difference was statistically significant (P<0.05).ConclusionNeedling peri-ocular points and abducens oculi can improve the strabismus angle, shorten treatment duration and reduce patient’s sufferings in treating postnatal abducens paralysis, significantly superior to conventional acupuncture at peri-ocular points.

Objective To study the effect of finasteride on hematuria associated with benign prostate hyperplasia. Methods We evaluated 61 patients with intermittent hematuria who were randomized to a finasteride treated group or control group.Routine urinoscopy was carried out once a week in all the 61 patients. Results In the untreated control group hematuria recurred in 20/31 within a year but in only 7/28 in the finasteride group,which was a statistically significant difference (P

To investigate manifestations and treatment of acute disseminated intravascular coagulation (DIC) in obstetrics, the medical records of 12 cases of acute DIC in obstetric patients admitted into our hospital from January 1993 to July 2001 were analyzed retrospectively. The result showed that the major causes of DIC in obstetric patients were amniotic fluid embolism and pregnancy induced hypertension. The main manifestations were bleeding, embolism or impairment of circulation. In all of the 12 patients accurate diagnosis was made, and treatment including elimination of causes, anti shock measures and prompt complement of coagulation factors. Nine patients received heparin early, 8 received antifibrinolytic agents rationally, and in 5 patients hysterectomy was performed. Nine patients were cured, 3 died. The key to decrease mortality of DIC in obstetric patients is to diagnose DIC early, to eliminate the causes promptly, to treat shock actively, and to use heparin and antifibrinolytic agents more rationally.

Objective Our research aimed to investigate the efficacy and the nursing characteristics of allogenic bone marrow mesenchymal stem cell (BM-MSCs) transplantation in HBV related acute-on-chronic liver failure (ACLF) patients.Methods A total of 91 HBV related ACLF patients were enrolled,among whom 45 patients received allogenic BM-MSCs transplantation via peripheral vein and other 46 patients received medical treatment only.We assessed the 12-week survival rates and the variation of model for end liver disease (MELD) score.Besides,we administrated comprehensive nursing for these patients in different stages of the transplantation.Results The cumulated survival of patients received BM-MSC transplantation was 75.6％,which was higher than the control group (54.5％).The level of total bilirubin and International Normalized Ratio (INR) had greatly improved.41 of 45 patients passed through perioperative period safely,without any severe adverse events.11 patients died due to exacerbation of liver failure,among whom 3 happened in perioperative period.But none was related with the operation.Conclusions Allogenic BM-MSCs transplantation can improve the survival rate of HBV related ACLF patients.The psychological nursing pre-operation,skilled operation,intensive care and observation post operation were beneficial to the patients' recovery after transplantation.

Conclusion Relevant nursing intervention for the hypoglycemia of chronic severe hepatitis can promptly correct low blood sugar , maintain normal level of blood sugar and avoid serious complications.

BACKGROUND:Emerging evidence demonstrates that low density lipoprotein receptor-related protein 1 (LRP1)isinvolved in lipid metabolism and regulation of inflammatory reaction.
OBJECTIVE:To explore the effectof lentivirus-induced knockdown of low density lipoprotein receptor-related protein 1 on cartilage damage and matrix metaloproteinase 13 in a rat model of osteoarthritis, so as to assess the role of low density lipoprotein receptor-related protein 1 in the pathogenesis of osteoarthritis.
METHODS:Sixty-fourSprague-Dawleyratswere included andramdomlydivided into four groups (n=16 for each): negative control group, no surgery; sham-surgery group, onlythearticular cavity of the knee was exposed; osteoarthritisplus shLRP1 group, rat osteoarthritis models were established by cutting anterior cruciate ligament and removing the medial meniscus partly folowed by an intra-articular injection of lentivirus-mediated siRNA at 2 days after surgery, once a week for 2 consecutive weeks; osteoarthritis group,an intra-articular injection of the negative control lentivirus was performed after surgery. Rats inthe four groups started running on theself-made electric treadmil from 5 days after modeling, 30 minutes per day,totaly 500 meters. Cartilage damage and matrix metaloproteinase 13 expression in cartilage tissues were determined at 2, 4, 6 weeks after surgery.
RESULTS AND CONCLUSION:Gross and pathological observations showed that lentivirus-induced knockdown of lowdensity lipoprotein receptor-related protein 1 aggravatedcartilage damage intherat model of osteoarthritis. At 6 weeks after surgery, Mankin’s scoreand matrix metaloproteinase 13 expression inthecartilage tissues in osteoarthritis plus shLRP1 groupweresignificantly increased compared with other three groups (P< 0.05). These findings indicate that a simulation model of osteoarthritis is developed by cutting anterior cruciate ligament and removing the medial meniscus partly combined with running onthe treadmil.
