Objective To study the relationship between the dynamic change of free DNA in cerebrospinal fluid (CSF)and the tissue injury in the patients with hypertensive intracerebral hemorrhage.Methods 54 cases of hypertensive intracerebral hemor-rhage were divided into 3 groups according to the glasgow coma scale(including 17 mild cases,21 moderate cases and 16 severe ca-ses).2 mL of CSF was collected for extracting free DNA on 1,3,7,15 d after stroke onset.The free DNA level was measured by the fluorescent real-time PCR.Results The free DNA level in the severe group was significantly higher than that in the mild and mod-erate groups.The free DNA level in the abnormal intracranial pressure group was higher than that in the normal intracranial pres-sure group;the intracranial infection group was higher than the non-infection group.Conclusion The free DNA level has certain value for diagnosing the craniocerebral injury in hypertensive intracerebral hemorrhage and is conducive to monitor the occurrence of postoperative complications.

Objective To evaluate the drill method to prepare for healthcare-associated infection (HAI)outbreak, and strengthen the control of HAI outbreak.Methods According to two cases of surgical site infection (SSI)re-ported by a neurosurgical department on January 16,2014,HAI outbreak emergency drill was started,SSI occurred from January 2012 to January 2014 were analyzed,specimens of air,object surface and hands of health care workers (HCWs)in the SSI-related operating room and neurosurgical intensive care unit(NSICU)were taken and analyzed. Results In July 2013,3 cases of SSI occurred in neurosurgical department (1 case was suspected of SSI,and didn’t per-form cerebrospinal fluid culture),SSI didn’t exceed 2 cases in the other months,and SSI outbreak couldn’t be confirmed. 16 specimens of air,object surface and hands of HCWs in operating room were taken,microbial detection results were all qualified.13 specimens of air,object surface and hands of HCWs in NSICU were taken,qualified rate was 61.54%;and mould was detected from 2 air specimens.24 disposable objects of neurosurgical department were performed bacterial cul-ture,3 were positive,and all were qualified after repeated detection.Conclusion HAI outbreak drill is helpful for HAI management professional personnel to grasp the method of HAI outbreak investigation method,improve the correct hand washing of surgeons and nurses,strengthen the standard operating procedure,and ensure the safety of pa-tients.

This article reviewed and summarized the experimental researches on the treatment of gouty arthritis (GA) with traditional Chinese medicine in recent years, which showed that the traditional or modified animal models of disease were widely used, and also concerned about the the model of integrating the disease and symptoms. However, few are about the application of combined disease and syndromes model. The mechanism research result shows that, single Chinese herb, component extract of Chinese herbs and Chinese herbal compound all play an important role in inhibiting inflammation, regulating signal pathway, anti-oxidation, reducing uric acid, increasing feeling of pain and regulating body metabolism.

One patient with chronic refractory wound in right lower leg was admitted to our department in June 2017, which experienced repeated ulceration for 4 years. On 4 days post admission, two bamboo sticks were taken out from the deep muscle of the right lower leg. The wound was repaired by perforator flap of posterior tibial artery in the right lower leg. The donor site was covered with split-thickness skin in the upper leg of the same side. On 7 days post operation, the flap and skin graft survived. During follow-up of 12 months, the flap had good appearance. This case suggests that the first thing for the treatment of chronic refractory wound is to find out the cause of wound.

Objective: To investigate the association between the preterm birth and low birth weight and parental thalassemia. Methods: Pregnant women and their husbands receiving prenatal examination in local hospitals or maternal and child health centers in Jingxi and Debao in Guangxi from January to December 2017 were selected as study subjects. A total of 758 pregnant women with pregnancy outcomes and their husbands, who were both or alone diagnosed with thalassemia through thalassemia gene detection, were selected as case group and 758 pregnant women with pregnancy outcomes and their husbands, who were negative in thalassemia gene detection and hemoglobin electrophoresis test were selected as control groups. The case group were further divided into mother group, father group and both mother and farther group. Clinical and pregnancy outcome data of the study subjects were collected for the analysis on the association between parental thalassaemia and preterm birth or low birth weight by the independent sample t test, χ² test and Cox regression analysis. Results: The incidence of preterm birth in case group and control group was about 6.5% and 1.6% and the incidence of low birth weight in case group and control group was about 7.3% and 0.8%. After adjusting for possible confounding factors, Cox regression analysis results showed that mother suffering from thalassemia (aRR=3.45, 95%CI: 1.35-8.81, P=0.010), fathers suffering from thalassemia (aRR=4.93, 95%CI: 2.16-11.21, P<0.001) and both mother and farther suffering from thalassemia (aRR=5.13, 95%CI: 2.62-10.04, P<0.001) were associated with preterm birth. Mother suffering from thalassemia (aRR=12.98, 95%CI: 4.91-34.30, P<0.001), fathers suffering from thalassemia (aRR=9.40, 95%CI: 3.40-25.95, P<0.001) and both mother and farther suffering from thalassemia (aRR=10.74, 95%CI: 4.44-26.00, P<0.001) were associated with low birth weight. The newborn whose parent all suffered from thalassemia had higher risks for preterm birth (χ²=22.72, P<0.001)and low birth weight (χ²=34.03, P<0.001) compared with those only with mother or father suffering from thalassemia. Conclusion Parental thalassaemia, including both sides and single side, might increase the risks of preterm birth and low birth weight for newborn, and the risks might be higher in newborn with both mother and father suffering from thalassaemia.

Objective To investigate the effects of non-Newtonian properties on hemodynamic characteristics of Fontan procedure in computational simulation. Methods A Fontan vascular model was reconstructed based on patient-specific medical images. The boundary conditions were set according to velocity profiles measured by real-time echocardiography. The Newtonian model and two non-Newtonian (Casson and Carreau) models were applied to analyze the hemodynamic parameters, including flow ratio (FR), energy loss (EL), wall shear stress (WSS) as well as non-Newtonian importance factor, so as to compare flow differences between the Newtonian model and non-Newtonian models. Results The rheological models had small effects on the FR. The EL of non-Newtonian models was higher than that of the Newtonian model, and the EL of Casson model was the highest. Flow recirculation and flow disturbance accompanied with low WSS were observed in inferior vena cava (IVC). At low inflow velocity, flow disturbance in IVC of Newtonian model was more obvious. The calculations of non-Newtonian importance factor suggested significant non-Newtonian viscosity in IVC. Conclusions Non-Newtonian viscosity is significant in IVC where low velocity and flow recirculation are observed. Non-Newtonian properties of the blood should be considered in patient-specific hemodynamic simulation of Fontan procedure.
