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 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

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.

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.

One patient died of liver and kidney failure, one gave up the treatment because of deterioration and the rest three got better. The hospital stay was 42~120 d with an average of 88.0 d. 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.

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.

BACKGROUND:Tumor necrosis factor α, as a pathogenic factor, induces the inflammatory reaction mainlyvia the activation of the nuclear factor kappa B signaling pathway. Low density lipoprotein receptor-related protein 1 (LRP1) is involved in the regulation of the inflammatory reaction induced by cytokines.
OBJECTIVE:To study the effect of knockdown of LRP1 on tumor necrosis factor α-induced inflammatory reaction.
METHODS: Primary cultured rat chondrocytes were transfected with lentivirus-mediated RNA interference to knockdown LRP1 gene. Three days after lentivirus transfection, chondrocytes were pretreated with Bay 11-7082 (10 μmol/L) for 30 minutes prior to the addition of tumor necrosis factor α (30 μg/L) for 30 minutes. Signaling protein and mRNA expressions in chondrocytes were detected by western blot assay and real-time PCR analysis, respectively. Chondrocytes were pretreated with or not Bay 11-7082 (10 μmol/L) 30 minutes prior to the addition of tumor necrosis factor α (30 μg/L) for 12 hours after starvation in DMEM for overnight, and the culture medium was colected for ELISA determination of matrix metaloproteinase 13 level.
RESULTS AND CONCLUSION:Tumor necrosis factor α receptor 1 expression was upregulated in chondrocytes after lentivirus-induced knockdown of LRP1. Increased expression of inducible nitric oxide synthase and activation of the nuclear factor kappa B signaling pathway were found after the addition of tumor necrosis factor α in shLRP1 group. Moreover, increased level of matrix metaloproteinase 13 was determined by ELISA. Taken together, knockdown of LRP1 up-regulates the expression of tumor necrosis factor α-induced inducible nitric oxide synthase and matrix metaloproteinase 13 through the activation of the nuclear factor kappa B signaling pathway.

Objective To compare the clinical effects of mini phalangeal external fixation and mini plate in the treatment of intraarticular fractures of the metacarpal bone head,and to provide a theoretical basis for clinical selection of surgical plan. Methods Seventy?four cases of metacarpal bone head intraarticular fractures treated in Huizhou People′s Central Hospital from March 2014 to March 2016 were selected as the research object. All cases were closed fractures and were randomly divided into the external fixation group and the mini plate group,37 cases in each group and treated respectively with the mini phalangeal external fixator and mini AO plate. The patients were followed up for 6 months to 1 year,the function of the metacarpophalangeal joint,the union of the fracture and the incidence of side effects were compared between the two groups. Results The excellent rates of the external fixation group at 6 months and I year after operation were 91. 9% ( 34/37) and 97. 3%( 36/37) respectively,which were significantly higher than those of the mini plate group ( 73. 0%( 27/37) ,81. 2%( 30/37 ) ) , the difference was statistically significant (χ2 = 7. 120, 7. 062, P<0. 05 ) . The complication rate of the external fixation group was 2. 7%( 1/37) ,which was significantly lower than that of the mini plate group ( 24. 3% ( 9/37 ) ) , the difference was statistically significant ( P=0. 014 ) . The average fracture healing time in the external fixator group was (2. 6±0. 4) months,which was significantly lower than that in the mini plate group (3. 1±0. 7) months,the difference was statistically significant (t=2. 40,P<0. 001) . Conclusion In the treatment of metacarpal bone head fracture,the external fixation has small trauma,can do cross joint fixation,and maintain a good fixation strength,and promote the healing of fracture and the recovery of metacarpophalangeal joint function. It is worthy of clinical application.
