Huoxue Tongmai Lishui method, a traditional Chinese medicine treatment for eliminating water, activating and promoting blood circulation, could inhibit fundus hemorrhage on experimental retinal vein occlusion (RVO) with high obvious effective rate, and improve symptoms in traditional Chinese medicine. The action mechanism may be related to reducing plasma viscosity and non-perfusion area, and the formation of collateral circulation.

Objective To compare the efficacy and safety of mirtazapine and buspirone on panic disorder.Methods 86 cases with panic disorder were divided into two groups: the mirtazapine(30～60 mg/d) group and the buspirone(15～30 mg/d) group.Hamilton Anxiety Scale(HAMA) was adopted to evaluate the efficacy.Safety was evaluated with Treatment Emergent Symptom Scale(TESS),laboratorial and physical examination.Results The effective rate of mirtazapine group and buspirone group was 90.7% and 83.7% respectively 8 weeks after treatment(χ2=1.17,P>0.05).The scores of HAMA of the mirtazapine group decreased more than that of the buspirone group 1 or 2 weeks after treatment(tt=2.94,P<0.01 and t=2.49,P<0.05 respectively).At the end of wk,But there was not significant difference between two groups 4 or 8 weeks after treatment(P>0.05).Some mild side-effects were observed in both groups.Conclusion Mirtazapine shows a similar effect to buspirone and takes effect earlier on panic disorder.

AIM: To investigate the association of osteoprotegerin ( OPG) gene single nucleotide polymor-phisms (SNPs), 163A/G (rs3102735) and 245T/G (rs3134069), with susceptibility to rheumatoid arthritis (RA) in Chinese Han population .METHODS:A total of 205 patients with RA and 171 healthy control subjects were enrolled into this study.Genotyping was performed by polymerase chain reaction-based restriction fragment length polymorphism and subsequently confirmed by DNA sequencing .Odds ratio ( OR) and 95%confidence intervals ( CI) were calculated for the risk genotypes and alleles .RESULTS: OPG gene polymorphisms 163A/G and 245T/G were conformed to the Hardy-Weinberg equilibrium .The statistical differences in the genotypes of AA , AG and GG at 163A/G locus were found in RA and controls.The G allele was associated with an increased risk of RA , with OR of 1.219 (95%CI:1.066~2.339).No significant difference was observed between RA group and control group with respect to genotypic and allelic frequencies of OPG gene 245T/G (P>0.05).CONCLUSION:The OPG gene 163A/G SNP may be associated with RA susceptibility , and G allele may be the risk factor for developing RA .

OBJECTIVE: To analyze social-psychological causes of acute exacerbation or re-decompensation of chronic tinnitus and provide theoretical basis for controlling and preventing tinnitus exacerbation and re-decompensation. METHOD: Systemic audiological tests and tinnitus handicap inventory were performed on 136 chronic tinnitus patients with acuteexacerbation or re-decompensation. For the patients with new hearing loss, a further investigation of living conditions and assessment of social support rating scale were utilized. The patients with relatively definite causes were treated accordingly. RESULT: (1) There were 89 patients complained of new changes of hearing, all of whom could tell the definite time point of tinnitus exacerbation, and 5 of them felt the exacerbation of hearing loss meanwhile. (2) Forty-two patients encountered adverse events on life or working, and tinnitus exacerbation occurred within several weeks to 3 months afterwards. Most of these patients could not tell the definite time point of tinnitus exacerbation or re-decompensation. Five cases of tinnitus exacerbation didn't tell any adverse events on life or working, but showed mood disorders, and the anti-anxiety treatment was effective to them. (3) Forty-seven cases without new hearing loss scored significantly lower in SSRS than healthy adults. CONCLUSION Emerging hearing loss is the main cause of acute exacerbation of chronic tinnitus. To find it in time and give effective treatment can save newly presented hearing loss, cure or relieve tinnitus. Adverse events in life(or working) and short of social support is another important cause of acute exacerbation of chronic tinnitus or decompensation recurrence, which suggests that social-psychological factors besides of hearing loss should be concerned in diagnosis and treatment of tinnitus.

Objective To study the natural developing characteristics of language skill of the autistic children. Methods 300 untreated autism children were included. Their developmental characteristics of individuals were evaluated by the Psycho-Educational Profile-Revised (PEP-R). Results The developmental quotient of most children (89.33%) was less than 70. And the developmental quotient gradually decreased with age (P<0.01). The scores of language performance and language verbal were deviation (P<0.01). Conclusion Language characteristics of autistic children without treatment is abnormal in development progress and order, and the situation would be worse with age.

Objective To study the effect of comprehensive Chinese medicine therapy,including Chinese herbal medicine fumigation,massage,and quadriceps exercise,on adipokines of visfatin and chemerin content in joint fluid of patients with knee osteoarthritis (KOA),and to explore its possible therapeutic mechanism for KOA.Methods A total of 60 cases of KOA patients were randomly divided into treatment group and control group,30 cases in each group.The treatment group was treated with comprehensive Chinese medicine therapy,and the control group was treated with Chinese medicine fumigation alone.After treatment for 2 weeks,the clinical efficacy of both groups was evaluated,and the changes in the scores of the Western Ontario and McMaster Universities Arthritis Index (WOMAC)were observed.Moreover,the contents of visfatin and chemerin in jointfluid were examined.Results (1) The total effective rate of the treatment group was 96.7％ and that of the control group was 83.3％,the difference being significant (P ＜ 0.01).(2) After treatment,WOMAC scores of both groups were obviously decreased(P ＜ 0.01 compared with those before treatment),and the decrease in the treatment group was superior to that in the control group (P ＜ 0.01).(3) The contents of visfatin and chemerint in joint synovial fluid of both groups were decreased (P ＜ 0.01 compared with those before treatment),and the decrease in the treatment group was superior to that in the control group(P ＜ 0.05).Conclusion The comprehensive Chinese medicine therapy of Chinese herbal medicine fumigation,massage and quadriceps exercise is effective for the treatment of KOA,and can decrease the contents of visfatin and chemerin in joint fluid of KOA patients,which may be one of its therapeutic mechanisms.

Objective: To determine imaging features that may help predict the presence of placenta accreta, placenta increta or placenta percreta on prenatal MRI scanning in order to identify the most diagnostic findings. Methods: The prenatal MRI scan data of placenta accreta, placenta increta or placenta percreta (placenta implantation group, n=15) and normal placenta(placenta normal group, n=15) diagnosed and treated by surgical pathology from January 2010 to December 2017 in the People's Hospital of Huadu District were retrospectively analyzed.Two expert MRI doctors were blinded to the patients' true diagnosis and were asked to score a total of 10 MRI features of the placenta and adjacent structures.The interrater reliability was assessed using kappa statistics.The features with a moderate kappa statistic or better(kappa>0.40 ) were then compared with the true diagnosis for each observer. Results: Eight of the scored features had an interobserver reliability of kappa>0.40: placenta previa(κ=0.89); abnormal uterine bulging(κ=0.57); intraplacental hemorrhage(κ=0.45); the presence of dark intraplacental bands on T₂W imaging(κ=0.76); flow-empty blood vessels in placenta(κ=0.67); border on placenta and uterus blurring(κ=0.63); heterogeneity of signal intensity on T₂-weighted(T₂W) imaging(κ=0.53); and continuity of myometrium was interrupted(κ=0.64). Using Fisher's two-sided exact test, there were statistically significant differences between the proportion of patients with placental invasion and those without placental invasion for three of the features: abnormal uterine bulging(P=0.015, P=0.011); heterogeneity of T₂W imaging signal intensity(P=0.006, P=0.013); and presence of dark intraplacental bands on T₂W imaging(P=0.032, P=0.010). Conclusion MRI can be a useful adjunct to ultrasound in diagnosing placenta accreta prenatally.Three features that are seen on MRI in patients with placental invasion appear to be useful for diagnosis: uterine bulging; heterogeneous signal intensity within the placenta; and the presence of dark intraplacental bands on T₂W imaging.

Objective To investigate the value of standardized ultrasound screening in diagnosis of fetal congenital heart disease (CHD) during the first trimester. Methods This study retrospectively analyzed the clinical data of 8 383 fetuses who received ultrasound screening during the first trimester in the Dongguan Maternal and Child Health Hospital from September 2015 to December 2016. Standardized ultrasound was performed to observe fetal heart position, apical direction, apical four-chamber view, three vessels and trachea view and the thickness of nuchal translucency (NT). Fetuses with thickened NT or fetal CHD observed during the first and second trimester were followed up. Pregnancy outcomes and the growth of newborns within one year after birth were recorded and analyzed. Pathological results after the termination of pregnancy were compared with the results of routine karyotyping and chromosome microarray analysis (CMA). Results (1) A total of 27 cases of fetal CHD were identified during the first trimester giving a detection rate of 0.32% (27/8 383). These included ten (37.0%) of single atrium and/or single ventricle, seven (25.9%) of endocardial cushion defect (including two complicated by persistent arterial trunk), three (11.1%) of hypoplastic right heart syndrome, three (11.1%) of interventricular septal defect, two (7.4%) of hypoplastic left heart syndrome, one (3.7%) of mirror-image dextrocardia and one (3.7%) of right atrial enlargement and severe tricuspid regurgitation. Nineteen out of the 27 cases had NT thickening (NT≥3.0 mm) and 17 of them had a cystic hygroma (NT≥6.0 mm). Among the 27 cases, 22 were terminated in the first trimester which autopsy results were consistent with ultrasound and the other five were rescreened during the second trimester. Thirteen out of the 27 cases received chorionic villus sampling, and seven of them were found to have chromosomal abnormalities by karyotyping and CMA, among whom one was microdeletion of 22q11. (2) Twenty-one cases of CHD were detected in the second-trimester ultrasound screening, including five initially identified in the first trimester. These cases included four (19.0%) of complex cardiac malformations (with three or more malformations), four (19.0%) of interventricular septal defect, three (14.3%) of dextroaortic arch, left subclavian artery vagus and 'U' shaped vascular ring, three (14.3%) of hypoplastic right heart syndrome (including one complicated by coronary artery-right ventricular fistula and one by interventricular septal defect), two (9.5%) of transposition of the great arteries, two (9.5%) of tetralogy of Fallot, one (4.8%) of hypoplastic left heart syndrome, one (4.8%) of Taussig-Bing anomaly and one (4.8%) of coarctation of the aorta. Among the 16 cases first identified in the second trimester, eight had NT thickening, including one with cystic hygroma. Among the 21 cases, two were lost to follow-up after being transferred to another hospital; four with negative results in karyotype analysis and CMA were delivered vaginally at term (37-40 gestational weeks) with 1-min Apgar scores of ten points and postpartum ultrasound of the baby was consistent with the second-trimester ultrasound screening; 15 were terminated and the autopsy confirmed those findings in the second-trimester ultrasound screening. Eleven out of the 21 cases received amniocentesis and five of them were found to be abnormal according to karyotype analysis and CMA, including one of microdeletion of 22q11. Conclusions Standardized first-trimester ultrasound screening is important and of great clinical value in the diagnosis of fetal CHD. Increased NT thickness could be a key indicator of fetal CHD and chromosomal abnormalities in early pregnancy. CMA may facilitate detecting the abnormality of genetic material in fetuses with normal chromosome karyotype.

OBJECTIVE: To investigate whether there is gender difference in the incidence and severity of tinnitus in medical staff (including doctors, nurses, and technicians). METHOD: A total of 354 people (all are medial stuff from hospitals in Guangzhou) were invited to be involved in the investigation and granted a self-reported questionnaire of tinnitus (designed by the authors; based on the scoring method of severity of tinnitus (Liu et al.). Statistical analysis on the data was performed using SPSS Statistics 17.0. RESULT: (1) The incidence of tinnitus of the sample was 43.22%, with that in female higher than in male (P < 0.05), and that in nurses higher than in doctors or technicians (P < 0.01). (2) The effect of working position factor on the incidence of prolonged tinnitus was significant (P < 0.01). However, no statistically significant gender difference was detected in the incidence of prolonged tinnitus. (3) There was no statistically significant difference of tinnitus severity scores between different genders or among different positions (P > 0.05). (4) There was statistically significant difference among the four sub-items of the questionnaire (P < 0.01), with the mean score of "occurred environment" higher than "the impact on sleeping", "the impact on everyday life", and "the impact on emotion". CONCLUSION (1) The effort-reward imbalance might be the key factor of the gender difference in the incidence of tinnitus. (2) For patients of tinnitus, improving the knowledge about their symptoms as well as levels of psychological resilience would be helpful to relieve the mental impairment of tinnitus.

OBJECTIVE: To probe the factors that affect the pure-tone threshold glycerol test and the distribution of frequencies in positive glycerol test. METHOD: We tested the pure-tone threshold before and after glycerol intake in patients with Meniere's disease, and then analyzed the positive rates,distribution of positive frequencies and the time when the maximum threshold changes appeared. RESULT: The positive rate of pure-tone glycerol test was 72.09%, of which the threshold descending rate was 47.67%, and the threshold rebounding rate was 24.42%; the pure-tone threshold changes of descending group and rebounding group were (17.41 +/- 9.92) dB, (13.53 +/- 4.64) dB respectively, and the differences were significant. The distribution of positive frequencies were 250 Hz, 125 Hz, 500 Hz, 1 kHz, 4 kHz, 2 kHz, 8 kHz in descending order. The maximum pure-tone threshold changes mostly appeared within 2 or 3 hours after glycerol intake. CONCLUSIONS Patient selection, test occasion and the judgement criteria may affect the positive rate of glycerol test; the positive frequencies distribute in the low-frequency region mainly; the maximum pure-tone threshold changes mostly appeared within 2 or 3 hours after glycerol intake.
