Objective To study the combined toxic effects of fluoride and aluminum on the liver of mouse and the probable mechanism. Methods Kunming mice were randomly divided into nine groups and treated with fluoride and aluminum through drinking water:control(tap water)group, 50 mg/L fluoride group, 150 mg/L fluoride group, 200 mg/L aluminum group, 600 mg/L aluminum group, 50 mg/L fluoride+200 mg/L aluminum group, 50 mg/L fluoride+600 mg/L aluminum group, 150 mg/L fluoride+200 mg/L aluminum group, 150 mg/L fluoride+600 mg/L aluminum group. After 24 weeks of treatment, the activity of ALT, AST, the content of TBIL, DBIL, IBIL, ALB, Ca, P and Mg in the serum was determined. Results Different doses of single fluoride or fluoride+aluminum led to significant different changes in the liver function(single fluoride:F=2.61, P0.05). Compared with the control group, the Ca level in the serum decreased in the exposed groups except 150 mg/L fluoride+600 mg/L aluminum group(P0.05). Conclusion The combination of fluoride and aluminum at certain levels has a toxic effect on the liver, but the combination of fluoride and aluminum at high doses shows an antagonistic effect.

ObjectiveTo observe the influence of Danshen injection on the serum levels of TNF-α,IL-6 in patients with acute pancreatitis(AP).Methods70 patients with AP were randomly divided into the experimental and control group.The two groups were given conventional anti-inflammatory,antisecretory,antispasmodic,inhibition of pancreatic secretion treatment,and the experimental group were treated with Danshen injection.Before trealment and 1,2,4,6 days after treatment,the serum TNF-α,IL-6 levels were measured in both groups.The time of blood and urine amylase(AMS) returned to normal was observed in both groups.Results2,4,6d after treatment,the serum TNF-α,IL-6 of the observation group were lower than that of the control group( all P ＜ 0.05 ) ;The blood AMS recovery time of the observation group was ( 2.55 ± 0.71 ) d,which had no significant difference with that of the control group(2.46 +0.82)d(t =0.32,P ＞0.05 ),while urinary AMS recovery time of the observation group was (4.30 ±0.72 ) d,which was shorter than that of the control group ( 6.84 ± 0.88 ) d ( t =0.02,P ＜ 0.05 ).ConclusionDanshen injection could reduce the serum TNF-α,IL-6 levels in patients with AP,and had no effect on the serum amylase,with the trend of faster lower urinary amylase.

BACKGROUND: Therapeutic methods for of peripheral facial nerve injury include surgery, physical therapy and drug treatment, but the treatment effect is not ideal in some certain cases. OBJECTIVE: To study the effect of autologous platelet rich plasma on repair of facial nerve injury. METHODS: The bilateral destroyed buccal nerve branches of the 10 white rabbits were put in silica gel nerve regeneration chamber, one side injected with platelet rich plasma as experimental group, the other side injected with normal saline as control group. The general observation, neuroelectrophysiology detection, histological observation, image analysis and evaluation of facial nerve regeneration recovery were performed at 8 weeks after surgery. RESULTS AND CONCLUSION: The action potential latency of the orbicularis oris at the experimental side was significantly lower than that at the control side, and the action potential amplitude (M wave) of compound nerve muscle of the experimental side was significantly higher than that of the control side (P < 0.01). Compared with the control side, the regenerative nerves of the experimental side were more mature with more regenerative axons, and the differentiation of myelin sheath was more mature and the thickness of myelin sheath was wel -distributed. Meanwhile, the diameters of axons were closed to the normal diameter, and the nerve axons were more intensive and arranged more regularly, the outer membrane of nerve fiber was thicker and the col agen fiber and elastic fiber layer were increased when compared with the control group. The number of regenerative axons of the control side was less, and the axons were distributed irregularly and poorly developed, and a large number of fibrous connective tissues were observed. The vacuolar degeneration at the control side was more than the experimental side. The regenerated nerve in the experimental side was better than the control side in the diameter of myelinated axon, area, myelin sheath thickness and axon count, and there were significant differences between two groups (P < 0.01). It indicates that platelet rich plasma has a promoting effect in the repair and regeneration of facial nerve.

Background: PTSD (Post-traumatic stress disorder, PTSD) had a great impact on health care workers during the COVID-19 (Corona Virus Disease 2019, COVID-19). Better knowledge of the prevalence of PTSD and its risk factors is a major public health problem. This study was conducted to assess the prevalence and important risk factors of PTSD among medical staff during the COVID-19. Methods: The databases were searched for studies published during the COVID-19, and a PRISMA (preferred reporting items for systematic review and meta-analysis) compliant systematic review (PROSPERO-CRD 42021278970) was carried out to identify articles from multiple databases reporting the prevalence of PTSD outcomes among medical staff. Proportion random effect analysis, I2 statistic, quality assessment, subgroup analysis, and sensitivity analysis were carried out. Results: A total of 28 cross-sectional studies and the PTSD results of doctors and nurses were summarized from 14 and 27 studies: the prevalences were 31% (95% CI [confidence interval, CI]: 21%–40%) and 38% (95% CI: 30%–45%) in doctors and nurses, respectively. The results also showed seven risks (p < 0.05): long working hours, isolation wards, COVID-19 symptoms, nurses, women, fear of infection, and pre-existing mental illness. Two factors were of borderline significance: higher professional titles and married. Conclusion Health care workers have a higher prevalence of PTSD during COVID-19. Health departments should provide targeted preventive measures for medical staff away from PTSD.Previous arti

Gallbladder abdominal wall fistula is usually due to the acute cholecystitis with-out timely treatment, which leads the formation of abscess around the gallbladder, the gallbladder adhering to the abdominal wall and the abscess infiltrating into the skin to form a spontaneous abdominal wall fistula. Patient with gallbladder abdominal wall fistula may have the symptoms of cholecystolithiasis and acute cholecystitis. Ultrasound examination can detect the situation of gallbladder conveniently, including the internal echo after formation of abscess, the connection between the gallbladder and abdominal cavity, and the blood flow signal, to clarify the diagnosis for the subsequent treatment. The authors share the diagnosis and treatment experiences of an elderly patient with gallbladder abdominal wall fistula.

Objective: To explore the characteristics and influencing factors of unintentional burns among left-behind children in rural areas of northern Guizhou, from the perspective of parents and children, to formulate strategies to prevent children from burns. Methods: A total of 508 left-behind children were recruited by using a multistage cluster sampling method, and 196 left-behind children’s families were also investigated with a self-designed questionnaire.The relative factors of burns were analyzed by unconditional logistic regression and multiple regression analysis. Results: The report rate of burns among left-behind children was 12.20%(62/508). Left-behind girls were a risk factor for burns(OR=1.81). The time of employment >5 years and the higher of the score of burn-related knowledge were the protective factors(OR=0.23, 0.38)(P<0.05). Only 64.80% of left-behind children’s main guardians had a burns-related knowledge score of 60 or more. The age of their main guardian, the number of minor children, and whether understand of unintentional injury were the influencing factors of burns score. Conclusion The report rate of burns among left-behind children in rural areas in northern Guizhou is still high; parents/guardians have a low cognition level of burns. The knowledge of burns should be strengthened and left-behind children should be cared to reduce the incidence of burns.
