Objective:To observe the correlation between blood cell-related inflammatory markers and diabetic retinopathy (DR).Methods:A cross-sectional study. From June 2020 to February 2022, the phase Ⅰ data of Beichen Eye Study in Tianjin Medical University Eye Hospital were included in the study. The research contents included questionnaires, routine systemic and ocular examinations, and laboratory blood cell-related indicators including mean platelet volume (MPV), platelet distribution width (PDW), neutrophils, and lymphocytes were performed. Neutrophil/lymphocyte ratio (NLR) and platelet/lymphocyte ratio (PLR) were calculated. The diagnosis and classification of DR referred to the international clinical classification standard of DR. Monocular or binocular DR was defined as DR patients. Participants were categorized into different groups based on whether they had diabetes and whether they had DR. The groups included the no-diabetes group, the diabetes without DR group, and the DR group. The Kruskal-Wallis H test was used for the comparison of quantitative data among multiple groups. Wilcoxon test was used for comparison between the two groups. The χ2 test was used to compare the categorical variables between groups. The variables was adjusted step by step, an unadjusted univariate model was built and the different parameters of the model Ⅰ, Ⅱ, Ⅲ were adjusted. The correlation between MPV, PDW, NLR, PLR, and DR in different models was analyzed by logistic regression. The receiver operating characteristic (ROC) curve was used to analyze the diagnostic efficacy of different NLR models for DR. Results:A total of 3 328 subjects were recruited. Among them, 1 121 (33.68 %, 1 121/3 328) were males and 2 207 (66.32 %, 2 207/3 328) were females. The median age of the included participants was 61.84 (6.05) years. The no-diabetes group, the diabetes without DR group, and the DR group were 2 679, 476, and 173, respectively. There was no significant difference in MPV and PLR among the three groups ( H=5.98, 1.94; P=0.051, 0.379). However, compared with no-diabetes group and the diabetes without DR group, PDW and NLR in the DR group showed an upward trend. In model Ⅲ with completely adjusted related factors, NLR was an independent risk factor for DR in no-diabetes group and DR group [odds ratio ( OR)=1.440, 95% confidence interval ( CI) 1.087-1.920, P=0.041], diabetes without DR group and DR group [ OR=1.990, 95% CI 1.440-2.749, P<0.001]. The results of ROC curve analysis showed that the diagnostic efficiency of NLR model Ⅲ was the highest, the area under the curve was 0.751 (95% CI 0.706-0.796, P<0.001), the optimal cutoff value was 0.390, and the sensitivity and specificity were 74.3% and 64.8%, respectively. Conclusions:The NLR of the DR group is significantly higher than that of the no-diabetes group and diabetes without DR group. NLR is an independent risk factor for DR.

Objective To investigate the efficacy of red and blue lights combined with Yufa Shengfa solution and 5% minoxidil solution in treating Ludwig type Ⅰ female androgenetic alopecia. Methods A total of 160 patients with Ludwig type Ⅰ female androgenetic alopecia were randomly divided into group A (Yufa Shengfa solution combined with 5% minoxidil solution), group B (red and blue lights therapy combined with Yufa Shengfa solution), group C (red and blue lights therapy combined with 5% minoxidil solution) and group D (red and blue lights therapy combined with Yufa Shengfa solution and 5% minoxidil solution), with 40 cases in each group. All the patients orally took compound glycyrrhizin tablets and Centrum multivitamins, and the therapeutic period was 3 months. Differences in hair diameter, hair density, and the number of hair follicles with multiple hairs were compared before and after treatment. Results The hair density, hair diameter, and the number of hair follicles with multiple hairs improved significantly in 4 groups compared with those before treatment, and group D showed the best improvement in these parameters, with significant between-group differences (P < 0.001). There were no serious adverse events or side effects during treatment in all the patients. Conclusion Red and blue lights therapy combined with Yufa Shengfa solution and 5% minoxidil solution is an effective non-surgical treatment for Ludwig type Ⅰ female androgenetic alopecia.

Objective:To systematically review the efficacy of preoperative corticosteroids use as an adjunctive treatment for rhegmatogenous retinal detachment associated with choroidal detachment (RRDCD).Methods:A evidence-based medicine study. The National Library of Medicine's PubMed, Web of Science, CNKI, and WanFang database were searched. Clinical controlled studies were selected the study object was RRDCD patients and the interventions were preoperative corticosteroids used as an adjunctive treatment. The search was conducted from January 2000 to January 2022. Duplicated, incomplete, or irrelevant articles were excluded. The conventional meta-analysis was used to evaluate the efficacy of corticosteroids used before surgery. The network meta-analysis was used to directly or indirectly compare the efficacy of oral corticosteroids or intravenous dexamethasone, peribulbar injection of glucocorticoids, prednisolone acetate eye-drops, intravitreal injection of triamcinolone acetonide (TA) and posterior sub-tenon injection of triamcinolone acetonide. Publication bias was evaluated by funnel plot.Results:According to the search strategy, 43 articles were initially retrieved, and 929 eyes of 13 articles were finally included for analysis; 6 and 10 articles were included in the traditional meta-analysis and the network meta-analysis. Among the 6 studies included in the conventional meta-analysis, 5 studies were retrospective and 1 study was a randomized controlled trial, involving a total of 575 eyes. The analysis results showed that there was no significant difference in the primary retinal reattachment rate between the corticosteroids group and the control group [odds ratio ( OR)= 1.53, 95% confidence interval ( CI) 0.67-3.53, P=0.314]. Among the 10 studies included in the network meta-analysis, 7 studies were retrospective trials, 2 studies were randomized controlled trials, and 1 study was prospective trial, involving a total of 575 eyes. The analysis results showed that there were significant differences in the primary retinal reattachment rate between the triamcinolone acetonide intravitreal injection group and the no corticosteroid treatment group ( OR=4.09, 95% CI 1.06-15.79). Sub-tenon injection triamcinolone acetonide had a higher incidence rate of ocular hypertension than oral glucocorticoid or intravenous dexamethasone ( OR= 4.47, 95% CI 1.42-14.13). Conclusions:Triamcinolone acetonide intravitreal injection before surgery can improve the primary retinal reattachment rate in RRDCD patients. Patients with the posterior sub-tenon injection of triamcinolone acetonide should be alert to elevated intraocular pressure.

Objective:To quantify any correlation between the severity of spinal curvature of an adolescent with idiopathic scoliosis and their cardiopulmonary exercise endurance.Methods:The cardiopulmonary exercise test (CPET) results and the full-length spinal X-rays in a standing position of 64 adolescents with idiopathic scoliosis were reviewed retrospectively. Independent t-tests were used to compare the two datasets obtained from those with left or right thoracic scoliosis. The correlation between the Cobb angle and cardiopulmonary exercise endurance was analyzed using Pearson correlation coefficients, multiple factor linear regression and two-stage linear regression.Results:After adjusting for gender, age, height and weight, the multiple linear regression analysis showed that the Cobb angle was significantly negatively correlated with maximum tidal volume (β=-0.013) and significantly positively correlated with the rate of respiration (β=0.421). The relationship between the Cobb angle and cardiopulmonary exercise endurance was non-linear. With a Cobb angle > 34°, a 1° increase reduces cardiopulmonary exercise endurance by a factor of 1.4 on average. At smaller Cobb angles the corresponding increase is about 0.87 times.Conclusions:The Cobb angle is a negative predictor of ventilation during exercise among adolescents with idiopathic scoliosis. The more severe a patient′s spinal curvature, the lower the cardiopulmonary exercise endurance is likely to be.

Objective: To investigate the relationship between the ubiquitin ligase E3 cirRNA(circHERC4/hsa＿circ＿0007113) and the senescence in Human embryonic lung fibroblasts(IMR-90)cells. Methods: The whole gene sequence of circHERC4 was obtained from circBase database and cloned into cirRNA expression vector pLC5-ciR. The recombinant pLC5-ciR(+) hsa＿circ＿0007113 was constructed in vitro. The recombinant plasmid was identified by PCR, enzyme digestion and sequencing. The recombinant plasmid was transfected into HEK293 T and IMR90 cells with liposome 2000 transfection reagent. The expression of circHERC4 in normal cells, empty vector group and recombinant vector group was detected by RT-PCR, and the senescence of cells was detected by SA-β-Gal staining. Cell proliferation was detected by CCK-8 method. Results: The overexpression vector of circHERC4 was successfully constructed by correct sequencing, and circHERC4 could be efficiently transfected in HEK293 T cells. Compared with the control group, the positive rate of SA-β-Gal staining in the recombinant vector group decreased(P<0.05), and the proliferation rate of cells increased(P<0.05). Overexpression of circHERC4 could improve the proliferation and inhibit the senescence in IMR90 cells. Conclusion It suggests that circHERC4 has potential function of anti-senescence, which lays a foundation for further study on the function of circHERC4.

Objective:To visualize the research hot spots and frontiers of non-surgical treatments for idiopathic scoliosis (IS) based on CiteSpace.Methods:The Web of Science Core Database and China National Knowledge Infrastructure from 1990 to 2020 were searched for studies of non-surgical treatments of idiopathic scoliosis. The time, distributions of nations, institutions, academic disciplines and keywords of literature were analyzed. With CiteSpace 5.7.R4 and Excel 2017, the visualized knowledge graphs and the data tables were generated.Results:A total of 822 studies including 548 articles in English and 274 articles in Chinese were retrieved, including 378 articles published during 2015—2020. The top three nations with higher number of published articles were USA (114 studies), Canada (77 studies) and China (68 studies). Studies covered 33 disciplines, including rehabilitation, engineering and orthopedics, and the betweenness centrality of rehabilitation medicine was the highest (0.59). The non-surgical treatment research was focused on adolescents (187 studies) and brace treatment (116 studies). From 1990 to 2014, the non-surgical treatment of IS mainly focused on the brace treatment (70.4%,69/98) in domestic studies. After 2014, comprehensive treatments such as exercise therapy and manual therapy gradually became the research trend in this field (61.3%,92/150). Research hotspots included different forms of brace treatment (betweenness centrality: 0.31), exercise (6 studies), manual therapy (3 studies), guide of medicine (2 studies), acupuncture therapy (2 studies) of non-surgical treatments. Among top 30 research institutions for domestic publication of Chinese literature, there were 22 tertiary hospitals, 1 secondary hospital, 5 schools, 1 comprehensive rehabilitation service organization, and 1 community health service center.Conclusion:The research content of non-surgical treatment for idiopathic scoliosis tends to be diversified, comprehensive treatment of exercise therapy, brace therapy, and manual therapy are currently the main research hotspots.

Objective To evaluate the efficacy of dexmedetomidine (DEX) mixed with ropivacaine for transversus abdominis plane block (TAPB) combined with general anesthesia in the patients undergoing laparoscopic colorectal surgery.Methods 58 patients scheduled for laparoscopic colorectal surgery under general anesthesia were randomly divided into 3 groups using a random number table:general anesthesia group (group A n =19),ropivacaine for TAPB group (group B n =20),and Dex mixed ropivacaine for TAPB group(group C n =19).After the end of anesthesia induction,ultrasound-guided bilateral TAPB was performed in B and C groups.20 ml of 0.25％ ropivacaine and 0.5 μg/kg DEX mixed with 0.25％ ropivacaine were injected into each side in groups B and C respectively.Patient controlled intravenous analgesia (PCIA) with sufentanil 100 μg and tropisetron 5 mg in 100 ml of normal saline was provided to all patients after surgery.When the visual analogue scale (VAS) score ≥ 4,tramadol 50-100 mg was intravenously injected as remedial analgesic.VAS scores were measured respectively after extubation and 6,12,24 h after surgery.The consumption of remifentanil during the operation and sufentanil during PCIA,and the number of successfully delivered doses and patients requiring rescue analgesic were recorded within 24 hrs after surgery.The occurrence of TAPB-related adverse events were also recorded.Results Compared with group A,the consumption of reminfentanil during the operation and sufentanil during PCIA,and the amount of successfully delivered doses and patients requiring rescue analgsia within 24hrs after surgery,were decreased in B and C groups (P ＜ 0.05).Furthermore,those numbers in group C are more less than group B in 12-24 hrs after the surgery.There were no significant difference among the three groups in the incidence of adverse reactions (P ＞0.05).TAPB-related complication were not found in B and C groups.Conclusions 0.5 μg/kg DEX mixed with 0.25％ ropivacaine for TAPB combined with general anesthesia can play a better analgesic effect in the patiens urdergoing laparoscopic colorectal surgery.

Objective To discuss the clinical characteristics of adrenal metastases,and summarize the experience of diagnosis and treatment.Methods From January 2008 to June 2018,the clinical data of 55 patients with adrenal metastases treated in our hospital were analyzed retrospectively.This study included 34 male patients and 21 female patients and the median age was 60 years old (ranged 55 to 84 years old).The median value of maximum diameter of adrenal metastases was 3 cm (ranged 1.9 to 10.3 cm);with 35 cases on the left side,13 cases right and 7 cases bilateral.The primary sites of malignant tumors were pancreas (18 cases,32.7％),lung (12 cases,21.8％),liver (6 cases,10.9％) and colorectum (6 cases,10.9％),respectively.Thirty-four cases were confirmed by pathology after adrenalectomy and 21 cases were confirmed by needle biopsy.Thirty cases were diagnosed synchronously with the primary tumor and 25 cases were metachronous.The median time from diagnosis of primary tumors was 13.3 months (ranged 2.0 to 97.4 months).42 cases of these 55 cases were diagnosed within one year.Treatment options for adrenal metastatic lesions included single adrenalectomy in 18 cases,adrenalectomy combined with radiotherapy 16 cases,single intravenous chemotherapy 10 cases,intravenous chemotherapy combined with non-operative treatment 10 cases and single radiotherapy 1 case.Results The main pathological types were adenocarcinoma (19 cases,34.5％),ductal adenocarcinoma (10 cases,18.2％),hepatocellular carcinoma (6 cases,10.9％) and clear cell carcinoma (4 cases,7.3％).Two cases were lost follow-up and the follow-up rate was 96％,the median follow-up time was 8 months (ranged 1 to 135 months).The median overall survival (OS) time of 55 patients was 5.3 months (ranged 1 to 134 months).The one-year survival rate was 23.6％ (13/55),the two-year survival rate was 12.7％ (7/55),the three-year survival rate was 9.1％ (5/55) and the five-year survival rate was 1.8％ (1/55).Conclusions Pancreatic cancer was the most common type of malignant tumor for adrenal metastases in our hospital.Most primary tumors and adrenal metastases were diagnosed synchronously or within one year.Comprehensive treatment with retroperitoneal adrenalectomy may improve the OS,however the overall prognosis is poor.

The fundus appearance of polypoidal choroidal vasculopathy (PCV) often demonstrates orange-red nodular lesions.ICGA reveals terminal dilation of the polyps with or without branching vascular networks.Currently,pachychoroid spectrum disease is a series of conditions included choroidal vasodilatation and increased permeability due to choroidal ischemia,choroidal thickening,retinal pigment epitheliopathy,and secondary pigment epithelial detachment,choroidal neovascularization and polyps included uncomplicated pachychoroid,pachychoroid pigment epitheliopathy,pachychoroid neovascularization,central serous chorioretinopathy,and PCV.These entities have the similar characteristics and prognosis,suggesting that they have the similar pathology.The recognition of PCV based on the pachychoroid spectrum disease can provide new ideas for the prevention and intervention of PCV.
