Efficacy of high-intensity focused ultrasound cycloplasty in glaucoma and its influencing factor / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To evaluate the efficacy of high-intensity focused ultrasound cyclo plasty(UCP)in the treatment of glaucoma and to investigate related influencing factors.METHODS: The study involved a total of 110 patients(134 eyes)who received UCP treatment between January 2019 and January 2022 at three medical centers: Tianjin Eye Aier Eye Hospital, Chongqing Aier Eye Hospital, and Chongqing Nanping Aier Eye Hospital. Patients were classified into three categories: primary angle-closure glaucoma, primary open-angle glaucoma, and secondary glaucoma. Best corrected visual acuity, intraocular pressure, and the usage of anti-glaucoma medications, etc., were recorded at 6 and 12 mo postoperatively.RESULTS: After 6 months of the UCP procedure, statistically significant differences in intraocular pressure were observed across all groups(all P<0.05). At 12 mo postoperatively, intraocular pressure of the primary angle-closure and primary open-angle glaucoma groups showed differences(all P<0.05). Notably, there were no significant changes in visual acuity at either the 6 or 12 mo compared to preoperative values across all patient groups(all P>0.05). Furthermore, the study identified a statistically significant correlation between the changes in intraocular pressure at 6 mo and factors such as age, history of previous glaucoma surgery, baseline white-to-white(corneal diameter), and the extent of UCP treatment(all P<0.05).CONCLUSION: The UCP procedure has been demonstrated to effectively lower intraocular pressure in patients with glaucoma. The efficacy appears to be influenced by variables including patient age, previous glaucoma surgery history, baseline white-to-white(corneal diameter), and the scope of UCP treatment. Importantly, UCP treatment did not adversely affect visual acuity, underscoring its favorable safety profile.

Objective:To investigate the correlation between the level of anti Mullerian hormone (AMH) in serum and ovarian interstitial blood flow in patients with polycystic ovary syndrome (PCOS).Methods:The clinical data of 88 patients with PCOS (PCOS group) admitted to Jiangshan Hospital of Traditional Chinese Medicine from June 2019 to June 2022 and 50 women of the same age who underwent physical examination during the same period (normal control group) were collected retrospectively. The patients in the PCOS group were divided into two subgroups according to the homeostatic model assessment for insulin resistance index (HOMA-IR) evaluated by the steady-state model. Among them, patients with HOMA-IR ≥ 2.69 were divided into the insulin resistance subgroup (PCOS-IR subgroup, 50 cases), and patients with HOMA-IR<2.69 were divided into the non-insulin resistance subgroup (PCOS-NIR subgroup, 38 cases). The level of AMH were measured by electrochemiluminescence, and ovarian interstitial blood flow indicators, including peak blood flow velocity (PSV), pulsation index (PI), and resistance index (RI) were monitored. Pearson correlation test was used to analyze the correlation between serum AMH and insulin resistance and ovarian interstitial blood flow. Meanwhile, Logistic linear regression model was used to analyze the influencing factors of ovarian interstitial blood flow in patients with PCOS.Results:The levels of AMH, HOMA-IR and PSV in the PCOS group were higher than those in the normal control group: (2.13 ± 0.84) μg/L vs. (0.84 ± 0.29) μg/L, 4.6(2.0, 8.4) vs. 1.8(0.5, 3.9), (10.05 ± 1.52) cm/s vs.(6.78 ± 0.89) cm/s; the PI and RI in the PCOS group were lower than those in the control group: (1.14 ± 0.26)% vs. (2.01 ± 0.53)%, (0.37 ± 0.18)% vs. (0.85 ± 0.33)%, there were statistical differences ( P<0.05). The levels of AMH, HOMA-IR and PSV in the PCOS-IR subgroup were higher than those in the PCOS-NIR subgroup: (2.68 ± 0.81) μg/L vs. (1.59 ± 0.43) μg/L, (10.74 ± 2.32) cm/s vs. (7.93 ± 1.90) cm/s, 7.2(3.1, 15.8) vs. 2.1(0.6, 5.3); the PI and RI in the PCOS-IR subgroup were lower than those in the PCOS-NIR subgroup: (0.88 ± 0.35)% vs. (1.52 ± 0.50)%, (0.29 ± 0.04)% vs. (0.51 ± 0.05)%, there were statistical differences ( P<0.05). Pearson correlation analysis showed that the level of AMH were positively correlated with PSV and HOMA-IR ( r = 0.694 and 0.540, P<0.05), but negatively correlated with PI and RI( r = - 0.687 and - 0.692, P<0.05). Logistic linear regression model analysis showed that AMH and HOMA-IR were risk factors for ovarian interstitial blood flow in patients with PCOS( P<0.05). Conclusions:The serum AMH level in patients with PCOS is abnormally high and increases with insulin resistance. At the same time, the imbalance of AMH expression plays an important role in the increase of abnormal ovarian interstitial blood flow.

Molecular structure and alternative splicing analysis of heat shock factors of Schistosoma japonicum / 中国血吸虫病防治杂志

Objective To clone and identify the heat shock factors(HSFs)of Schistosoma japonicum and analyze its molec?ular structure and alternative splicing pattern. Methods The New Zealand rabbits were infected with the cercariae of Schistoso?ma japonicum and were killed and dissected 42 days post?infection,and the adult worms of S. japonicum and the livers of the rabbits were harvested. Then,the total RNA was extracted by using Trizol reagent. The Sj?hsf open reading frame(ORF)and the alternative splicing fragments were amplified by RT?PCR from the female,male and egg samples,then cloned and verified by enzyme digestion and sequencing. DNAMAN 8.0,InterPro,Mega 6 combined with the Internet databases were utilized to clarify the gene structure,functional domains,alternative splicing pattern,and the homology and phylogenetic tree of HSFs. Re?sults Sj?hsf ORF and the alternative splicing fragments were amplified from the female,male and egg samples of S. japonicum by RT?PCR. After cloning,the positive recombinant plasmids pBSjHSFf?F,pBSjHSFf?M,pBSjHSFf?E containing Sj?hsf ORF, pBSjHSFs?F,pBSjHSFs?M,pBSjHSFs?E with Sj?hsf alternative splicing fragments were identified by enzyme digestion and se?quencing. Three alternative splicing Sj?hsf isoforms were observed through sequence analysis:Sj?hsf?isoform1(2 050 bp),Sj?hsf ?isoform2(2 086 bp)and Sj?hsf?isoform3(2 111 bp);the GenBank accession numbers were KU954546,KX119143 and KX119144,respectively. All the three isoforms located in the same Contig SJC_S000780 of S. japonicum genome and all ex?pressed at female,male and egg stages,but Sj?hsf?isoform1 with a high?level expression. Sj?HSF?isoform1(671 aa)and Sj?HSF?isoform2(683 aa)had DBD(DNA binding domain),HR?A/B and HR?C domains,while Sj?HSF?isoform3(282 aa)stopped in advance without HR?C domain. Phylogenetic tree analysis of HSFs illustrated that Sj?HSFs belonged to HSF1 family,with a close phylogenetic relationship to Sm?HSFs. Conclusions There are three alternative splicing isoforms of Sj?HSF existing in the female,male and egg stages of S. japonicum,but Sj?HSF?isoform1 expresses in a high?level. This study lays the foundation for further study on molecular mechanisms of Sj?HSFs in regulating the heat shock response system.

<p><b>OBJECTIVE</b>To examine the expression profile and immunofluorescence localization of the major egg antigen p40 of Schistosoma japonicum (Sjp40) during granuloma formation in the liver of infected New Zealand white rabbits.</p><p><b>METHODS</b>New Zealand white rabbits were infected with S. japonicum cercariae, and the livers were harvested at 29 and 45 days post-infection (dpi). The total RNA of the liver tissues was extracted for expression profiling of Sjp40 by quantitative reverse transcription-PCR (qRT-PCR) with GAPDH of S. japonicum as the endogenous reference gene. The expression of Sjp40 in the liver were detected by Western blotting using anti-Sjp40 monoclonal antibody (mAb) 9G7 or anti-Toxoplasma gondii tSAG1 mAb Y3A8 (control) as the primary antibody. Paraffin sections of the liver were prepared for observing egg granuloma formation using HE staining and for indirect immunofluorescence assay of Sjp40 location in the trapped eggs and egg granulomas.</p><p><b>RESULTS</b>The level of Sjp40 mRNA in the eggs trapped in rabbit livers was significantly higher at 45 dpi than that at 29 dpi (P<0.05), and Western blotting confirmed the presence of Sjp40 protein in the rabbit livers at both 29 and 45 dpi. Immunofluorescence assay demonstrated localized expression of Sjp40 in the immature eggs in the rabbit liver at 29 dpi, but at 45 dpi fluorescence was detected in clusters of mature eggs containing miracidium and in the surrounding egg granulomas.</p><p><b>CONCLUSIONS</b>The transcriptional levels of Sjp40 significantly increased with the maturation of eggs trapped in the rabbit livers. Sjp40 protein spread from the eggs to the surrounding egg granuloma at 45 dpi when acute liver granulomatous lesions occur, suggesting that Sjp40 plays a key role in egg granulomas formation in the livers of infected New Zealand white rabbits.</p>

Analysis on 21 cases of chylous fistula after neck lymph nodes dissection / 重庆医学

Objective To discuss the prevention and management method for chylous fistula after neck lymph node dissec‐tion .Methods Totally 1 793 cases of neck lymph node dissection in this department from January 2005 to September 2014 were retrospectively analyzed .The clinical data in the cases of chylous fistula occurred after operation were summarized .Results Twenty one cases of chylous fistula occurred ,accounting for 1 .17% ,in which 13 cases were cured by the local compressed bandaging and continuous negative pressure drainage;5 cases adopted the conventional method for 2-3 d ,but under the ineffective condition ,then they were treated by combining with somatostatin pumping (somatostatin 6 mg+0 .9% normal saline 48 mL ,2 mL/h ,lasting for 24 h ,for successive 2-3 d) and finally cured;3 cases were cured after reoperation .Conclusion Prevention is the best treatment for chylous fistulas ,local compression bandage plus continuous negative pressure drainage is the main method for treatment of chylous fistulas after neck dissection .The combined therapy with somatostatin can increase the close rate of chylous fistulas;for the patients with long persistent time ,large drainage volume and invalid conservative therapy should adopt the remedial measure of operation .
