Objective:To investigate the prevalence of cataracts, the surgical coverage, and postoperative visual acuity of adults in Ningxia.Methods:A cross-sectional study using multistage cluster random sampling was conducted.Ten survey sites in Ningxia were selected and the population aged 18 years and over was surveyed with questionnaire, height and weight measurements, visual acuity, intraocular pressure, fundus photography and slit-lamp examinations.Cataract prevalence and its influencing factors were analyzed.Cataract prevalence, surgical coverage and presenting visual acuity (PVA) and best corrected visual acuity (BCVA) after surgery were investigated in different age groups of the examined population.The study adhered to the Declaration of Helsinki and was approved by the Ethics Committee of the People's Hospital of Ningxia Hui Autonomous Region (No.[2023]-LL-010).Participants signed informed consent prior to the examination.Results:A total of 6 145 people should be examined, and 5 721 people were actually examined, with an examination rate of 93.10%.The study population consisted of 2 558 males, accounting for 44.71%, and 3 163 females, accounting for 55.28%, with ages ranging from 18 to 93 years old and an average age of (64.27±13.48) years.Among them, 1 180 patients diagnosed with cataract, with a cataract prevalence of 20.62%.The prevalence of cataract increased with age and decreased with education level, showing statistically significant differences ( χ2=1 091.32, 581.92; both at P<0.01).The prevalence of cataract was significantly higher among people with hypertension, diabetes mellitus, hyperlipidemia, and coronary heart disease than those without these diseases ( χ2=274.65, 118.15, 78.05, 182.71; all at P<0.01).Cataract surgery was performed in 245 cases in the cataract patient population, with a surgical coverage rate of 20.76%.Of the 245 cases, 229 cases were implanted with IOLs, with an implantation rate of 93.40%.The social burden rate of cataract blindness was 2.29%, and increased with age.Of the 339 eyes that underwent cataract surgery, 241 had a PVA≥0.3, accounting for 71.09%, and 272 had a BCVA≥0.3, accounting for 80.24%. Conclusions:In Ningxia, cataracts are still the main cause of vision impairment and blindness in the elderly, and the social burden rate of cataract blindness is high.Moreover, the coverage rate of cataract surgery is low, so both the coverage and quality of surgery need improvement.

Objective To explore the effects of long non-coding RNA(lncRNA)small nucleolar molecule RNA host gene 12(SNHG12)targeting inhibition of miR-495-3p/phospholipinositol-3-kinase(PI3K)/protein kinase B(Akt)signaling pathway on the proliferation,migration and invasion of prostate cancer cells.Methods The expressions of SNHG12 and miR-495-3p in prostate cancer tissues and cells(LNCaP,C4-2,DU145)were detected with real-time fluorescence quantitative PCR(qRT-PCR).After DU145 cells were divided into si-NC,si-SNHG12,si-SNHG12+anti-miR-NC and si-SNHG12+anti-miR-495-3p groups,the expressions of SNHG12 and miR-495-3p were detected with qRT-PCR;the targeting relationship between SNHG12 and miR-495-3p was determined with dual luciferase assay;cell proliferation was assessed with MTT assay;cell migration and invasion were evaluated with Transwell assay;the protein expressions of proliferating cell nuclear antigen(PCNA),N-cadherin,and E-cadherin were detected with Western blot.Results The expressions of SNHG12 were significantly increased,while the expression of miR-495-3P was significantly decreased in prostate cancer tissues and cells(LNCaP,C4-2,DU145)(P＜0.05).Knockdown of SNHG12 decreased DU145 cell activity,lowered the protein expressions of PCNA and N-cadherin,reduced the number of migrating and invading cells,but increased the protein expression of E-cadherin(P＜0.05).SNHG12 targeted and negatively regulated miR-495-3p,and down-regulation of miR-495-3p reversed the effects of SNHG12 knockdown on the proliferation,migration and invasion of prostate cancer cells.Compared with the si-NC group,the si-SNHG12 group had significantly decreased expressions of p-PI3K and p-Akt(P＜0.05).Compared with the si-SNHG12+anti-miR-NC group,the si-SNHG12+anti-miR-495-3p group had significantly increased protein expressions of p-PI3K and p-Akt(P＜0.05).Conclusion lncRNA SNHG12 can promote the proliferation,migration and invasion of prostate cancer cells through targeted inhibition of miR-495-3p/PI3K/Akt signaling pathway.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Objective:To explore the relationship between serum levels of transforming growth factor- β1 (TGF- β1), vascular endothelial growth factor (VEGF) and tumor markers and local recurrence after breast-conserving surgery in patients with breast cancer. Methods:104 patients with breast cancer who underwent breast-conserving surgery in Xi’ an Central Hospital from Jan. 2020 to Dec. 2022 were selected and followed up for 1 year after surgery. According to the occurrence of local recurrence, they were divided into recurrence group ( n=16) and non-recurrence group ( n=88). The levels of serum TGF- β1, VEGF and tumor markers [carbohydrate antigen 125 (CA125), carcinoembryonic antigen (CEA) ] were compared between the two groups of patients. Univariate and multivariate Logistic regression analyses were used to analyze the influencing factors of local recurrence after breast-conserving surgery. Receiver operating characteristic (ROC) curve was applied to analyze the predictive value of TGF- β1, VEGF, CA125 and CEA on local recurrence after breast-conserving surgery. Results:The levels of VEGF, TGF- β1, CAl25 and CEA in recurrence group [ (358.83±38.00) ng/L, (849.90±74.19) U/mL, (18.34±1.61) ng/L and (40.20±5.64) ng/mL] were higher than those of (296.05±39.57) ng/L (742.85±79.96) ng/L, (14.97±1.66) U/mL and (32.79±4.72) ng/mL in non-recurrence group (all P<0.05). Lymph node metastasis, postoperative adjuvant therapy, tumor diameter and TNM staging were independent risk factors of local recurrence after breast-conserving surgery (all P<0.05). The areas under the ROC curves (AUCs) of serum VEGF, TGF- β1, CAl25 and CEA in predicting local recurrence after breast-conserving surgery were 0.847, 0.834, 0.925 and 0.935 respectively. The AUC of CEA was the largest, with sensitivity of 85.23% and specificity of 100% (all P<0.05) . Conclusions:The levels of TGF- β1, VEGF, CAl25 and CEA in patients with local recurrence after breast-conserving surgery are increased, and their levels are more effective in predicting local recurrence after breast-conserving surgery. Local recurrence after breast-conserving surgery is also affected by lymph node metastasis, postoperative adjuvant therapy, tumor diameter and TNM staging.

Electromagnetic stimulation is an important neuromodulation technique that modulates the electrical activity of neurons and affects cortical excitability for the purpose of modulating the nervous system. The phenomenon of inverse stochastic resonance is a response mechanism of the biological nervous system to external signals and plays an important role in the signal processing of the nervous system. In this paper, a small-world neural network with electrical synaptic connections was constructed, and the inverse stochastic resonance of the small-world neural network under electromagnetic stimulation was investigated by analyzing the dynamics of the neural network. The results showed that: the Levy channel noise under electromagnetic stimulation could cause the occurrence of inverse stochastic resonance in small-world neural networks; the characteristic index and location parameter of the noise had significant effects on the intensity and duration of the inverse stochastic resonance in neural networks; the larger the probability of randomly adding edges and the number of nearest neighbor nodes in small-world networks, the more favorable the anti-stochastic resonance was; by adjusting the electromagnetic stimulation parameters, a dual regulation of the inverse stochastic resonance of the neural network can be achieved. The results of this study provide some theoretical support for exploring the regulation mechanism of electromagnetic nerve stimulation technology and the signal processing mechanism of nervous system.

Primary ciliary dyskinesia (PCD) is a highly heterogeneous recessive inherited disorder. FAP54, the homolog of CFAP54 in Chlamydomonas reinhardtii, was previously demonstrated as the C1d projection of the central microtubule apparatus of flagella. A Cfap54 knockout mouse model was then reported to have PCD-relevant phenotypes. Through whole-exome sequencing, compound heterozygous variants c.2649_2657delinC (p. E883Dfs*47) and c.7312_7313insCGCAGGCTGAATTCTTGG (p. T2438delinsTQAEFLA) in a new suspected PCD-relevant gene, CFAP54, were identified in an individual with PCD. Two missense variants, c.4112A>C (p. E1371A) and c.6559C>T (p. P2187S), in CFAP54 were detected in another unrelated patient. In this study, a minigene assay was conducted on the frameshift mutation showing a reduction in mRNA expression. In addition, a CFAP54 in-frame variant knock-in mouse model was established, which recapitulated the typical symptoms of PCD, including hydrocephalus, infertility, and mucus accumulation in nasal sinuses. Correspondingly, two missense variants were deleterious, with a dramatic reduction in mRNA abundance from bronchial tissue and sperm. The identification of PCD-causing variants of CFAP54 in two unrelated patients with PCD for the first time provides strong supportive evidence that CFAP54 is a new PCD-causing gene. This study further helps expand the disease-associated gene spectrum and improve genetic testing for PCD diagnosis in the future.

Objective:To investigate the therapeutic effect of open suture and selective suture in patients with high complexity anal fistula and its effect on anal function and complications.Methods:Prospectively selected 174 patients with high complex anal fistula who were hospitalized in the Anorectal Surgery Department of the Second People′s Hospital of Yibin City from December 2018 to December 2021 as the study subjects, including 138 males and 36 females, aged from 26 to 45 years, with an average of (35.20 ± 8.86) years. According to the admission order of patients, grouped them into single and double numbers, with single numbers being the control group ( n=87) and double numbers being the observation group ( n=87). The control group was treated with traditional incision and thread hanging therapy, while the observation group was treated with selective suture through incision and thread hanging therapy. Compared the surgical time, blood loss, surgical cost, wound healing time, and anal function at 6 months after surgery between the two groups of patients. Compared the treatment effects of two groups of patients at 6 months after surgery. Compared the postoperative complications within 6 months and recurrence within 1 year between the two groups. The measurement data subject to normal distribution were expressed by mean ± standard deviation( ± s). The two groups were compared by independent sample t test, and the count data were compared by Chi-square test. Rank sum test was used for comparison of hierarchical data. Results:The surgical time in the observation group was higher than that in the control group [(44.30 ± 8.11) min vs (42.18 ± 7.25) min, ( t=-2.44, P<0.05], and the surgical cost was higher than that in the control group [(1184.81 ± 372.68) yuan vs (835.28 ± 320.03) yuan, t=-8.75, P<0.001]. There was no statistically significant difference in blood loss data between the two groups [(19.57 ± 6.07) mL vs (18.35 ± 5.25) mL, t=-1.88, P>0.05]. The length of wound healing time in the observation group was lower than that in the control group [(24.18 ± 4.35) d vs (29.35 ± 5.08) d, t=11.09, P<0.001]. The anal function score of the observation group at 6 months after surgery was lower than that of the control group [(4.80 ± 1.21) score vs (6.71 ± 1.35) score, t=14.72, P<0.001]. All patients did not experience any loss of follow-up. In the comparison of treatment effects 6 months after surgery, the observation group had a better efficacy rating than control group ( Z=3.86, P<0.001). At 6 months after surgery, the incidence of complications in the observation group was lower than that in the control group [2.30% (2/87) vs 10.34% (9/87), χ2=4.76, P<0.05]. One year after surgery, the recurrence rate in the observation group was lower than that in the control group [2.30% (2/87) vs 10.34% (9/87), χ2=4.76, P<0.05]. Conclusion:The application of incision and thread-drawing selective suture in the treatment of patients with high complex anal fistula is beneficial to the treatment effect of patients, reduces postoperative complications, and protects the anal function of patients, with good use value.

OBJECTIVES: Gastrointestinal endoscopy plays an important role in the diagnosis and treatment of gastrointestinal diseases. The satisfaction degree of gastrointestinal endoscopy can directly affect the patient's compliance and further impact the treating effect. At present, there is no scale to evaluate the satisfaction degree of gastrointestinal endoscopy in China. This study aims to develop a satisfaction scale of gastrointestinal endoscopy suitable for national conditions and to evaluate its reliability and validity, which provides a tool for clinic to evaluate patients' satisfaction with gastrointestinal endoscopy. METHODS: The original gastrointestinal endoscopy satisfaction scale was compiled by literature review, consulting senior endoscopists and experts. Through the first round of survey about 120 patients, the original scale was analyzed and modified according to the results to get the gastrointestinal endoscopy satisfaction scale (formal scale). The formal scale was used to conduct the second round of survey about 200 patients. The reliability and validity of the scale were analyzed and evaluated according to the survey results. RESULTS: The reliability of the original scale was good but the validity was poor. The formal scale had 2 dimensions and 10 items, the Cronbach's alpha and split-half reliability were 0.889 and 0.823. The structure validity index χ²/df was 2.513, root mean square error of approximation (RMSEA) was 0.094, goodness of fit index (GFI) was 0.914, adjusted goodness of fit index (AGFI) was 0.861, comparative fit index (CFI) was 0.946, normed fit index (NFI) was 0.915. The aggregate validity was general, the discriminative validity was good, and the direct score of patients was strongly correlated with the total score of the scale. CONCLUSIONS The gastrointestinal endoscopy satisfaction scale has good reliability and validity, which can be used as a tool to evaluate patients' satisfaction with gastrointestinal endoscopy in China.
