Tardive dyskinesia (TD) is a medication-induced hyperkinetic movement disorder, generally manifested as involuntary spasms or choreiform movements of the tongue, lower face and jaw, and limbs (lasting at least several weeks). It occurs after using neuroleptic medication for at least several months, causing irreversible injuries to the nerve system and significantly impacting patients′ daily function. This review summarizes recent research progress regarding TD risk factors, possible pathogenesis, clinical characteristics, assessment and identification, and treatment and management approaches. The goal is to raise awareness of TD to archive early prevention and identification, standardize treatment, and improve patients′ prognosis and quality of life.

Objective:To assess the efficacy and safety of common medication treatments on Kaposiform hemangioendothelioma (KHE) and tufted angioma (TA).Methods:PubMed, Embase, Web of Science, CNKI and Wanfang database were searched to find out the observational studies on medication treatment of KHE and TA. R-3.6.2 was used for calculate the pooled response rate and pooled adverse events rate. Meta analyses were performed according to KHE and TA with and without Kasabach-Merritt phenomenon (KMP) respectively. SPSS 22.0 was used to compare the pooled rates among each therapy.Results:A total of 30 studies regarding the medication treatment of KHE and TA were identified in this meta-analysis. Analyzed medicines included glucocorticoid, vincristine, sirolimus, propranolol, combination therapy of vincristine and glucocorticoid. The pooled results indicated that when referring therapy on KHE and TA with KMP, the pooled response rate of combination therapy (98.34%) and sirolimus (96.43%) was higher than that of other therapies, and the difference was statistically significant. The pooled adverse events rate of sirolimus (5.53%) was relatively higher than other modalities, with no statistically significance. As for therapy on KHE and TA without KMP, sirolimus (94.23%) had higher pooled response rate than glucocorticoid (31.25%), vincristine (46.15%) and propranolol (22.86%), with statistically significant differences. The pooled adverse events rate of sirolimus was 23.81%.Conclusions:Our findings indicate that for KHE and TA with KMP, combination therapy (sirolimus + glucocorticoid) and vincristine have the best efficacy, while the adverse events rate of sirolimus is relatively high. For KHE and TA without KMP, sirolimus has the highest response rate, but there is also a risk of serious adverse events. Glucocorticoid and vincristine have comparable response rate, which both inferior to sirolimus.

To examine the efficacy and safety for metformin in treating antipsychotic-induced dyslipidemia.
 Methods: Two randomized placebo-controlled trials were included in the analysis. A total of 201 schizophrenia patients with dyslipidemia after treatment with an antipsychotic were collected, and the patients were divided into two groups: a 1 000 mg/d metformin group (n=103) and a placebo group (n=98). The clinical symptoms and metabolic indicators such as body weight, blood glucose, and blood lipids were assessed at baseline, the 12th week and the 24th week after treatment respectively.
 Results: After metformin treatment, the mean difference in the low-density lipoprotein cholesterol (LDL-C) value between the metformin group and the placebo group was from 0.16 mmol/L at baseline to -0.86 mmol/L at the end of the 24th week, which was decreased by 1.02 mmol/L 
(P<0.01). At the 24th week, the LDL-C was more than 3.37 mmol/L in 25.3% patients in the metformin group, which was significantly lower than that in the placebo group (64.8%) (P<0.01). Compared with the placebo group, there were significant changes in the weight, body mass index (BMI), insulin, insulin resistance index, total cholesterol and triglyceride, and high-density lipoprotein cholesterol (HDL-C) in the metformin group (all P<0.05). The treatment effects on weight and insulin resistance appeared at the 12th week and further improved at the 24th week, but the effects on improving dyslipidemia only significantly occurred at the end of the 24th week.
 Conclusion: The metformin treatment is effective in improving antipsychotic-induced dyslipidemia and insulin resistance, and the effect to reduce the antipsychotic-induced insulin resistance appears earlier than the effect to improve dyslipidemia.

Objective To observe the effect of different explosion impulse on rabbit lung injury and decide the death curve,so as to provide a reference for the prediction of lung injury.Methods Six healthy male New Zealand white rabbits with weight of 2.0-2.5 kg and age of (6 ± 1)months were selected.The rabbits were put 0.5 m,0.6 m,0.7 m,0.9 m,1.0 m,and 1.2 m away from 90 g TNT to carry out the blast injury experiment.The characteristic parameters of blast shock wave and general lung injury were recorded.Based on the experimental results combined with theoretical analysis,the changes of rabbit lung injury depending on the explosion distance as well as the rabbit death curve were determined.Results After the 90 g TNT explosion,the peak overpressure of shock wave and the corresponding specific impulse decreased quickly with the increase of explosion distance.The peak overpressure was 0.79 MPa and the specific impulse was 82 Pa · s at the explosion distance of 0.5 m.The peak overpressure was 0.1 MPa and the specific impulse was 34 Pa · s at the explosion distance of 1.2 m.The rabbits at 0.5 m and 0.6 m died,the rabbit at 0.7 m was severely injured,and the rabbits at 0.9 m,1.0 m,and 1.2 m were slightly injured.The dependence of lung injury degree on the explosion distance under 90 g TNT explosion was established based on dimensional analysis theory.The lung injury degree was exponentially attenuated with the explosion distance:φ =(R/0.6)-5.64(φ represented lung injury degree,and R represented the explosion distance).Considering the combined injury effects of peak overpressure of shock wave and its specific impulse on rabbit lung,the death curve of rabbit was determined:(p-0.1) (I-59) =2.6 (p represented peak overpressure,and I represented specific impulse).The criterion of "overpressure-specific impulse" was used to estimate the death of rabbit,and the death curve of rabbit was determined as (p-0.1)(I-59) =2.6(p represented peak overpressure and I represented specific impulse).The critical overpressure was 0.1 MPa and the critical specific impulse was 59 Pa · s.Conclusions Under the explosion condition of 90 g TNT,the relationship between degree of lung injury in rabbits and explosion distance is established.Death curve of rabbits is determined based on the damage effect of shock wave peak overpressure and specific impulse on the lungs of rabbits,which is significant for predicting the blast injury.

BACKGROUND:Biological dressing A (porcine Xenoderm) and Physiotule Ag (Coloplast) show good effects on the absorption of exudates, adhesion and anti-bacteria in treatment of degree Ⅱ facial burns. OBJECTIVE:To observe the effectiveness of biological dressing Aversus Physiotule Ag after early debridement of degree Ⅱ facial burns. METHODS:A total of 15 patients with superficial degree Ⅱ facial burn and 10 patients with deep degree Ⅱ facial burns were included. Symmetric facial area of the same patient with the same depth of burn was divided into two parts of same size for treatments. One side was randomly selected as the experimental side, and treated with biological dressing A. The other was selected as the control side and treated with Physiotule Ag. We compared wound healing time, infection, times of changing dressings, skin after healing, drug change comfort and dressing comfort between the two sides. RESULTS AND CONCLUSION:In patients with superficial grade Ⅱ facial burn, times of changing dressings and drug change comfort were better in the experimental side than in the control side (P < 0.05), but the dressing comfort was better in the control side than the experimental side (P< 0.05). No significant difference in wound healing time, infection and skin after healing was detected between the two sides. In patients with deep degree Ⅱ facial burns, wound healing time, times of changing dressings, skin after healing and drug change comfort were better in the experimental side than in the control side (P < 0.05), but the dressing comfort was better in the control side than the experimental side (P< 0.05). No significant difference in infection was detectable between the two sides. Above findings suggested that the therapeutic effects of biological dressing A and Physiotule Ag were similar in treatment of degree Ⅱ facial burns. Biological dressing A in repair of deep degree Ⅱ facial burns promotes the wound healing andelevates the quality of healing.

Objective To examine the advanced oxidation protein products (AOPP) in patients with acute coronary syndrome(ACS) and discuss the relationship between oxidative stress with the development of atherosclero-sis(AS). Methods Plasma were collected in 59 acute myocardial infarction (AMI) patients including 35 patients underwent selective PCI,24 patients underwent emergency PCI,43 unstable angina pectoris(UA) patients and 10 non-coronary artery disease (non-CAD) patients. All cases underwent coronary angiography (CAG). Plasma was collected immediately,post-24 hours and post-48 hours after admission. AOPP was determined by measurements of absorbance (A) at 340 nm under acidic conditions via spectrophotometry. Results AOPP was (236.42±30.41) ( n = 35 ), ( 207.84±29.50 ) mmol/L ( n = 35 ), ( 227.79 ± 35.18 ) mmol/L ( n = 31 ) respectively immediately, post-24 hours and post-48 hours after admission in AMI ( selective PCI ), ( 239.95 ±39.94 ) mmol/L ( n = 43 ), (175.92 ±29.46) mmol/L(n =38) ,and (156.54 ±28.29) mmol/L(n =35) in UA group and (57.41 ± 13.60) mmol/L( n = 9 ), (56.11 + 11.90) mmol/L ( n = 10 ) and ( 61.75 ± 12.28 ) mmol/L ( n = 8 ) in non-CAD group. Compared with normal group ( without CAD ) , significantly higher plasma AOPP was detected in AMI ( selective PCI) and UA patients ( P < 0.05 ). AOPP level was significantly increased in AMI selective PCI patients as compared with that of emergency PCI group immediately and post-24 hours after admission( P <0.01 ) ,and post-48 hours after admission( P < 0.05 ), but there was no statistical significance between emergency PCI and UA group( P > 0.05 ). Conclusions Oxidative stress is an important step in the development of atherosclerosis, and the higher levels of AOPP in ACS patients show that AOPP may be as good markers in these patients.
