Background Transscleral diode laser cyclophotocoagulation (TDCP) was used to later stage of glaucoma in the past.However,the indications of TDCP are expanding gradually over time and there are more and more reports about its application in different stages and different types of glaucoma.Objective This study was to compare the clinical efficacy of TDCP and trabeculectomy for primary acute angle-closure glaucoma (PAACG) with persistent ocular hypertension.Methods Ninety-five PAACG patients with persistent ocular hypertension were retrospectively analyzed.The patients were divided into TDGP group (62 eyes of 56 cases) and trabeculectomy group (44 eyes of 39 cases) based on the difference of treating fashions.The clinical outcomes were compared between the two groups with the evaluating indexes of visual acuity,intraocular pressure (IOP) before and 1 week,3 months and the end of following-up as well as the number of drug used and the re-treatment.Results The demography was matched between the two groups (all at P＞0.05).The number of eyes with visual improvement was significantly different among the groups (x2 =30.927,P =0.002) in the TDCP group.Compared with before treatment,the number of visual improvement in 1 week after treatment was significantly raised (x2 =16.778,P =0.002).No significant differences were seen in the eye number of visual improvement in various timepoints after treatment (all at P＞0.008).Also,the eye number of visual improvement was significantly different among the different timepoints (x2 =44.345,P＜0.001),and statistically significant change was found between the preoperation and postoperative 1 week (x2 =23.725,P＜0.001).However,there were no significant differences in the eye number of visual improvement in various timepoints after operation each other (all at P＞0.008).The IOP was insignificantly altered among the groups at various timepoints (Fgroup =3.836,P =0.053),but the change was significantly different over time (Ftime =757.078,P＜0.001).The postoperative IOP was significantly higher than that of preoperation in both groups (all at P＜0.001).The proportion of eyes using lowering-IOP drugs was 48.4％ in the TDCP group,and that in the trabeculectomy group was 27.3％,showing a significant difference between them (x2 =4.796,P =0.029).The retherapy was performed in 20 eyes (32.3％) and 2 eyes (4.5％) in the TDCP group and the trabeculectomy group,respectively.Conclusions The short-term lowing-IOP effecacy of TDCP is similar to trabeculectomy,but the longterm lowing-IOP efficacy of TDCP is not good.Compared with the trabeculectomy,TDCP shows more simple operation,less time-consuming during the surgery and milder tissue damage,but the eyes continuing to use anti-glaucomatous drugs or re-therapy are increased.

PurposeTo explore the value of ultrasound radio frequency technique in the quantitative evaluation of common carotid artery intima-media thickness (IMT) and elasticity change in patients with dyslipidemia, and to discuss the influence of high density lipoprotein cholesterol (HDL-C) upon carotid artery structure and elasticity function. Materials and Methods A hundred and fifty patients with abnormal serum lipid were selected as case group and further divided into three groups: group A--50 patients with hyperlipidemia and high HDL-C, group B--50 patients with hyperlipidemia and normal HDL-C, group C--50 patients with hyperlipidemia and low HDL-C. Meanwhile, 50 healthy people were enrolled in the study as control group (group D). The ultrasound radio frequency-data technique was employed to analyze the influence of hyperlipidemia and HDL-C upon IMT, CC,β, PWV and AIx.Results The IMT,β, PWV and AIx in group B were higher than those in group D, but group B had lower CC (the differences with statistic significance,t=5.141, 4.219, 4.898, 4.142 and-3.758,P<0.01). Compared with group A, group B had higher IMT,β, PWV and AIx and lower CC (the differences with statistic significance,t=3.425, 2.807, 2.913, 2.209 and-2.091,P<0.05 orP<0.01). Compared with group B, group C had higher IMT,β, PWV and AIx and lower CC (the differences with statistic significance,t=4.937, 2.195, 3.337, 2.067 and-3.049, P<0.05 orP<0.01). Group A had higher IMT and PWV than group D (the differences with statistic significance,t=2.236 and 2.407,P<0.05), but CC,β, and AIx showed no difference between group A and group D (t=-1.693, 1.845 and 1.967,P>0.05). In patients with hyperlipidemia, the increase of HDL-C led to the reduction of the common carotid artery IMT and wall stiffness and the increase of elasticity and vice versa.Conclusion The ultrasound radio frequency technique could measure the real-time common carotid artery IMT and elasticity automatically and accurately, thus provides reliable quantitative index for the evaluation of early artery structure and change of function in lipid lowering therapy.

Objective:To observe the clinical efficacy of filiform needle combined with fire needles for cervical radiculopathy(CR)due to wind-cold obstructing the meridians. Methods:A total of 60 patients with CR due to wind-cold obstructing the meridians were randomized into an observation group and a control group,with 30 cases in each group.The control group was treated with filiform needle treatment,and the observation group was treated with additional fire needle point-pricking treatment.The visual analog scale(VAS)and 20-point scale of CR developed by Yasuhisa TANAKA(YT-20)were scored before treatment and after 1,2,3,and 4 weeks of treatments.The tenderness threshold was measured.The local skin temperature was measured by an infrared thermal imager.A safety evaluation was performed after treatment. Results:After treatment,the VAS score in the observation group at each time point was lower than that in the control group(P<0.05).The YT-20 score,tenderness threshold,and local skin temperature in the observation group were all higher than those in the control group(P<0.05).The VAS score in the observation group at each time point after treatment was lower than that before treatment(P<0.05),and the YT-20 score,tenderness threshold,and local skin temperature at each time point were higher than those before treatment(P<0.05).After 3 and 4 weeks of treatments,the VAS score in the control group was lower than that before treatment(P<0.05),and the YT-20 score,tenderness threshold,and local skin temperature were higher than those before treatment(P<0.05).The group factor effects of VAS and YT-20 scores,tenderness threshold,and local skin temperature between the two groups were statistically significant(P<0.05).There was no significant difference in the time effect and the interaction effect between time and group(P>0.05). Conclusion:Filiform needle combined with fire needle or applied alone both can relieve neck pain in patients with CR due to wind-cold obstructing the meridians,and improve the temperature of the neck.The combination of filiform needle and fire needle works more quickly and has better efficacy.

Objective:To compare and explore the diagnostic performance of adding value of transabdominal and transvaginal contrast-enhanced ultrasound (CEUS) to Ovarian-Adnexal Reporting and Data System (O-RADS US) risk stratification and management system in differential diagnosis of adnexal masses.Methods:A total of 180 adnexal masses with solid components in 175 women were enrolled retrospectively between September 2021 and November 2022. All patients underwent routine Doppler ultrasound examinations and CEUS examinations. Among these masses, 107 masses underwent with transabdominal CEUS, 58 masses underwent with transvaginal CEUS, and 15 masses underwent both transvaginal and transabdominal CEUS. All patients were scheduled for surgery and pathological results served as the reference standard. Routine Doppler ultrasound and CEUS images and video were reviewed by a subspecialty radiologist using Vuebox software. The O-RADS US was downgraded or upgraded according to the CEUS characteristics of the masses. The diagnostic accuracy was assessed using ROC curve analysis. The area under the ROC curve (AUC) was calculated to compare the diagnostic performance of adding value of transabdominal and transvaginal CEUS to O-RADS US.Results:The diagnostic performance of adding transabdominal and transvaginal CEUS to O-RADS US were both significantly higher than of O-RADS US alone (transabdominal CEUS: AUC 0.83 vs 0.76, P=0.018; transvaginal CEUS: AUC 0.92 vs 0.81, P=0.013). Combination of transvaginal CEUS and O-RADS US was superior to that of combination of transabdominal and O-RADS US in the differential diagnosis of adnexal masses ( P=0.047). When the maximal diameter of adnexal masses ≤40 mm, transabdominal combined with O-RADS US presented the lowest diagnostic performance, with an AUC of 0.73. Conclusions:Combination of transvaginal CEUS and O-RADS US was superior to that of combination of transabdominal and O-RADS US in assessing adnexal masses with solid components. When the maximal diameter of adnexal masses ≤40 mm, transvaginal CEUS examination was recommended.

OBJECTIVETo investigate the distribution patterns of mosquito and mosquito-borne viruses in Dehong prefecture, Yunnan province, China.

METHODSMosquito samples were collected using the mosquito traps from five counties of Dehong prefecture on July, 2007 and 2010. Mosquito were cell cultured for viral isolation, and positive isolates were identified using RT-PCR and sequence analysis.

RESULTSA total of 43 634 mosquito comprised of 29 species representing six genera were collected. Culex tritaeniorhynchus and Anopheles sinensis comprised 78.69% and 14.77% of the total. Six strains of viruses were isolated from the mosquito pools. RT-PCR and phylogenetic analysis revealed three strains from Cx. tritaeniorhynchus, identified as genotype I Japanese encephalitis virus (JEV). One strain was identified from Cx. tritaeniorhynchus, as Getah virus (GETV). Two strains isolated from Cx. tritaeniorhynchus and Anopheles vagus were identified as Culex pipiens pallens Densovirus (CppDNV).

CONCLUSIONCx. tritaeniorhynchus had been the major species of mosquito and mainly transmitting vector of mosquito-borne viruses in Dehong prefecture. Genotype I JEV, GETV and CppDNV were the vectors causing transmission of mosquito-borne diseases in this area. Data from phylogenetic analysis showed that these newly discovered isolates seemed to have had close relationship with those viruses previously circulating in Yunnan and other provinces of China.
