Objective To compare the clinical safety and efficacy of CT-guided hook-wire localization of≤10mm pulmonary ground-glass nodule(GGN)via different path ways before video-assisted thoracoscopic surgery(VATS).Methods The clinical data of a total of 128 patients with 10 mm pulmonary GGN,who received CT-guided hook wire localization before VATS at The Third Hospital of Mianyang of China between July 2018 and March 2023,were retrospectively analyzed.According to the puncturing localization path way mode,the patients were divided into vertical puncturing group(n=88)and non-vertical puncturing group(n=40).The number of puncturing times,the time spent for puncturing localization,the success rate of puncture,the operation time of VATS,and puncture-related complications of the two groups were recorded.Results No statistically significant differences in the gender,age,smoking history,GGN location,puncture position,nodule size,density characteristics of GGN,emphysema,and nodules-pleura distance existed between the two groups(all P＞0.05).Compared with non-vertical puncturing group,in vertical puncturing group the number of puncturing times was smaller,the time spent for localization was shorter,the incidence of pneumothorax was lower,and the operation time of VATS was shorter,the differences in all the above indexes between the two groups were statistically significant(all P＜0.05);and the subgroup analysis of patients whose GGN was overlapped with rib shadow obtained the same results.Binary logistic regression analysis revealed that non-vertical puncturing and the number of puncturing times were the independent risk factors for the occurrence of pneumothorax.Conclusion CT-guided hook-wire localization of≤10mm pulmonary GGN before VATS is clinically safe and effective.Under the condition when the lesion can be localized within the range of 2.0cm and the shadow overlapping of GGN with the rib and blood vessel can be effectively avoided,vertical puncturing path way mode should be preferred,which can effectively reduce the incidence of pneumothorax and shorten the operation time of VATS.

Objective:To systematically evaluate the effect of cognitive behavioral therapy (CBT) in elderly patients with depression.Methods:The randomized controlled trials on the effect of CBT in elderly patients with depression, published until December 15, 2022, were searched in PubMed, CINHAL, Cochrane Library, China Biology Medicine, China National Knowledge Infrastructure, WanFang Data, and VIP. Two researchers independently screened the literature, extracted data, and used the revised Cochrane risk of bias tool for randomized trials (ROB 2.0) to evaluate the quality of the included studies. Statistical analysis was conducted using Stata 16.0, and the quality of evidence was rated using Appraisal of Guidelines for Research and Evaluation (GRADE) predictor software.Results:A total of 11 randomized controlled trials were included, with a total of 833 elderly patients with depression. Randomized effect models were used to analyze outcome indicators such as depression, anxiety, and quality of life by combining effect quantities. Meta-analysis and GRADE evidence quality showed that compared to the control group, medium quality evidence showed that CBT could relieve depression in elderly depression patients with a statistical difference [ SMD=-1.58, 95% CI (-2.16, -0.99), P<0.05]. Low quality evidence suggested that CBT could alleviate anxiety in elderly depression patients also with a statistical difference [ SMD=-2.25, 95% CI (-4.04, -0.47), P<0.05]. Very low quality evidence indicated that CBT did not significantly improve the quality of life in elderly depression patients compared to conventional or pharmacological treatment [ SMD=-0.09, 95% CI (-2.07, 1.88), P>0.05] . Conclusions:Existing evidence suggests that CBT can alleviate depression and anxiety in elderly depression patients, but its improvement in quality of life is not yet significant. Treatment feedback and forms of CBT may become a research focus in recent years on intervention for elderly depression patients.

Objective To analyze the causal relationship between gastroesophageal reflux disease (GERD) and chronic obstructive pulmonary disease (COPD) based on the bidirectional two-sample Mendelian randomization (MR). Methods Genetic variation information of GERD and COPD was obtained from Genome-Wide Association Studies (GWAS) and used as instrumental variables. Inverse variance-weighted (IVW), weighted median and MR-Egger methods were used for MR analysis, and sensitivity analysis was performed to validate the robustness of the results. Results A significant positive correlation was observed between genetically predicted GERD and the incidence risk of COPD, but there was no statistical association between COPD and the incidence risk of GERD. Positive IVW result showed that the odds ratio (OR) was 1.305 7, the 95% confidence interval (95%CI) was 1.114 4 to 1.529 8, and the P value was 0.000 9; the reverse IVW result showed that the OR was 0.982 3, the 95%CI was 0.917 4 to 1.051 9, and the P value was 0.610 4. Sensitivity analysis did not find any potential bias. Conclusion MR analysis shows that GERD is a risk factor for COPD, and treating GERD may help prevent or delay the progression of COPD.

ObjectiveTo compare the therapeutic effects of oral Chinese medicines （including Chinese patent medicines） on coronary artery disease （CAD） by the Bayesian network Meta-analysis. MethodThe randomized controlled trials of treating CAD with oral Chinese medicines were retrieved from the China National Knowledge Infrastructure （CNKI）， Wanfang Data， VIP， PubMed， Web of Science， Embase， and Cochrane Library from the inception to December 1， 2022. The Cochrane risk of bias assessment tool was used to evaluate the quality of the included articles. The direct meta-analysis was performed to compare the performance of oral Chinese medicines alone and in combination with Western medicine in the treatment of CAD in terms of intima-media thickness （IMT）， vascular endothelial function， plaque score， hypersensitive C-reactive protein （hs-CRP）， total cholesterol （TC）， triglyceride （TG）， high-density lipoprotein cholesterol （HDL-C）， low-density lipoprotein cholesterol （LDL-C）， and total response rate. Furthermore， the Bayesian network Meta-analysis was performed to compare the therapeutic effects of different Chinese medicines. ResultA total of 41 articles were included. The direct meta-analysis results showed that Chinese medicines combined with Western medicine outperformed Western medicine alone in recovering all the indicators of CAD. The Bayesian network meta-analysis yielded the following results. In terms of the total response rate， modified Huangqi Guizhi Wuwutang and Sanqi Huayu pills had obvious advantages over other Chinese medicines. In terms of IMT and plaque score， Xiaoban Huazhuo decoction， Yiqi Tongluo formula， Ruangan Jiangzhi capsules， and Guanxin Shutong capsules had obvious advantages over other Chinese medicines. In terms of blood lipid indicators， Shenqi Roumai mixture， Ruangan Jiangzhi capsules， Xiaoban Huazhuo decoction， Qiwei Sanxiong decoction， and Sanqi Huayu pills were superior to other Chinese medicines. The Chinese medicines above mainly had the functions of activating blood， resolving stasis， resolving phlegm， and dredging vessels. ConclusionThe combination of oral Chinese medicines and Western medicine is effective in treating CAD. Clinicians can use the drugs targeting abnormal indicators according to the results of this Bayesian network meta-analysis combined with the actual situation of patients to achieve better therapeutic effects.

Objective:To explore the clinical effect of antibiotic bone cement combined with delayed lateral supramolleolar perforator fascial flap in the treatment of diabetic foot(DF).Methods:From April 2020 to July 2021, a total of 6 patients with DF were treated with antibiotic bone cement combined with delayed lateral supramolleolar perforator fascial flap. The patients were 5 males and 1 female, aged from 45 to 67 years old with an average of 56.2 years old. The wounds were all located in dorsal foot, 4 in right foot and 2 in the left. The wound area was 2.4 cm×5.0 cm-6.5 cm×10.0 cm. The depth of wound were: 3 cases up to tendon layer, and 3 cases up to metatarsal bone. Two of the wound were complicated with metatarsal osteomyelitis. The wounds at Wagner grade 3 in 4 patients and grade 4 in 2 patients. The flap size was 3.0 cm×6.0 cm-8.0 cm×11.0 cm. All of the wounds were repaired with delayed supramolleolar perforator fascia flap after debridement, application of antibiotic bone cement and fumigation with Sanhuang decoction(a traditional Chinese medicine). The affected limbs were externally fixed with plaster and raised after surgery, and the colour, temperature, tension and capillary reaction of the flaps were closely observed. Stitches were removed 2 weeks after surgery and rehabilitation of the affected limb was performed. Regular follow-up was made postoperatively. The appearance of flaps and the scar of donor and recipient sites were observed. The foot and ankle function were evaluated by the American Orthopaedic Association foot and Ankle Surgery(AOFAS) score scale.Results:Six cases of DF had no recurrence of wound infection. All flaps survived well. The average follow-up time was 6(3-14) months. The postoperative follow-up revealed satisfactory appearance of the flap, only linear scars remained in the donor and recipient sites. The function of foot and ankle recovered well with full weight-bearing and normal walk. AOFAS scores ranged from 81 to 95.Conclusion:It is an effective method to treat DF by applying antibiotic bone cement combined with delayed superior lateral malleolus perforator fascial flap. The operation is simple, safe and can cut down the time of treatment, quickly control the wound infection. It deserves further trials.

Objective:To analyze the repeatability of keratometry and astigmatism values measured by the OPD-Scan Ⅲ and the agreement of the parameters measured by OPD-Scan Ⅲ and Pentacam.Methods:A diagnostic test study design was adopted.Fifty patients (100 eyes) with refractive errors, aged from 21 to 35 years old, were selected from Second Affiliated Hospital of Nantong University and Lixiang Eye Hospital of Soochow University during August 2018.Spherical equivalent, astigmatim degree and axis were measured by Autorefraction.Corneal biometric measurements were measured three times continuously with the above two instruments.Keratometry values at the flat axis (K1), keratometry values at the steep axis (K2), astigmatim degree, axis, vector parameters J0 (Jackson cross cylinder at 0°or 180°) and J45 (Jackson cross cylinder at 45°) were recorded.Intraclass correlation coefficient (ICC) was used for repeatability analysis.Wilcoxon signed rank test, Spearman correlation analysis and Bland-Altman graphs were employed to analyze the comparability.This study adhered to the Declaration of Helsinki and was approved by an Ethics Committee of Lixiang Eye Hospital of Soochow University (No.SLER2018112). Written informed consent was obtained from each patient prior to any examination.Results:The ICC of K1, K2, astigmatism, astigmatic axis, J0 and J45 measured by OPD-Scan Ⅲ were all greater than 0.900; the ICC of the astigmatism measured by Pentacam was 0.896, and the ICC of the other parameters measured by Pentacam were greater than 0.900; The values of K2, astigmatism, J0 and J45 measured by OPD-Scan Ⅲ were greater than those measured by Pentacam, and the differences were statistically significant (all at P<0.05). The values of K1, K2, astigmatism degree, axis, J0 and J45 measured by OPD-Scan Ⅲ were positively correlated with those measured by Pentacam (r s=0.981, 0.982, 0.900, 0.737, 0.921, 0.703, all at P<0.01). The 95% agreement of limits (LOA) of K1, K2, astigmatism, axis, J0 and J45 measurement difference between OPD-Scan Ⅲ and Pentacam were -0.52-0.50 D, -0.39-0.59 D, -0.37-0.48 D, -17.29°-20.38°, -0.12-0.24 D and -0.22-0.28 D, respectively. Conclusions:OPD-Scan Ⅲ has high credibility in measuring corneal refractive power and astigmatism degree, but its 95% LOA of astigmatism axis is too large to be accepted clinically.

OBJECTIVE: To investigate the role of Cyr61 in angiotensin Ⅱ (AngⅡ)-induced functional changes in HEK293 cells and explore the mechanism. METHODS: Cyr61 knockdown in cultured HEK293T cells was achieved by transfection of the cells with CRISPR/Cas9 KO plasmid. The changes in apoptosis and expression levels of Cyr61 and Bcl-2 in the cells with or without Cyr61 knockdown in response to treatment with 10 mol/L AngⅡ for 48 h were analyzed using flow cytometry, qRT-PCR and Western blotting. RESULTS: The cells with Cyr61 knockdown showed significantly decreased expression of Cyr61 protein as compared with the control cells ( < 0.05). AngⅡ treatment for 48 h significantly increased the expression of Cyr61 and lowers the expression of Bcl-2 at both the protein and mRNA levels in HEK293T cells. In HEK293T cells with Cyr61 knockdown, AngⅡ treatment resulted in significantly increased expression of Bcl-2 in HEK293T cells as compared with that of the control group ( < 0.05). AngⅡ treatment caused significantly increased apoptotic rate in HEK293T cells as compared with the cells with Cyr61 knockdown [(26.94 ± 3.73)% (3.87 ± 0.83)%, < 0.05), and the apoptosis rate was significantly lowered to (15.76 ± 1.31)% in HEK293T cells with Cyr61 knockdown following AngⅡ treatment ( < 0.05). CONCLUSIONS The up-regulation of Cyr61 expression is related with AngⅡ-induced injury in HEK293T cells, and down-regulating Cyr61 expression can effectively protect HEK293T cells against AngⅡ-induced injury.

OBJECTIVE:To provide reference for the formulation of correct antifungal treatment strategy,and to promote stan-dard use of antifungal agent. METHODS:A retrospective survey was conducted for 138 haematologic patients from May 2013 to May 2014 in a third grade class A hospital,of whom all had used antifungal drugs during hospitalization. We collected all patients' information and analyzed it statistically. RESULTS:Of 138 haematologic patients,3 were proven IFD (all were Candida infec-tion),6 were probable IFD,12 were possible IFD,and 117 were undefined IFD. The positive rates of fungi pathogenic detection, fungal smear,G-test,and GM-test were 15.3%,9.4%,6.4% and 23.4% respectively. 6 kinds of antifungal were used,and vori-conazole had the highest frequency,followed by fluconazole,itraconazole,amphotericin B,caspofungin and micafungin. 62.3%patients used only one kind of antifungal,but 15.9% patients used 2 or more kinds of antifungal. The average medication course was 20.5 days(1 day to 125 days). Irrational drug use showed improper drug selection,unreasonable dose,and replacing antifun-gal with insufficient basis. CONCLUSIONS:The antifungal use in haematologic patients in the hospital is consistent with the re-quirements of guidelines,but there are still some issues as insufficient antifurgal drug treatment course to be further standardized.

BACKGROUND:Bone marrow mesenchymal stem cel s have a low survival rate after implanted into the ischemic myocardium. However, hypoxia preconditioning (HPC) may enhance bone marrow mesenchymal stem cel proliferation and promote its survival rate. OBJECTIVE:To explore whether Pim-1 is involved in HPC protecting against apoptosis of bone marrow mesenchymal stem cel s and the relevant mechanism. METHODS:Bone marrow mesenchymal stem cel s were respectively subjected to HPC for 0, 6, 12, and 24 hours. The expression of Pim-1 and apoptosis-related genes were detected by RT-qPCR and western blot. Then, the best hypoxic preconditioning time was determined as 12 hours. Then, bone marrow mesenchymal stem cel s were assigned to one of the fol owing groups:control (without HPC), 12-hour HPC, 12-hour HPC+Pim-1 inhibitor groups. Flow cytometry analysis was used to detect the cel apoptosis, Transwel assay to analyze the cel migration ability in each group, and JC-1 kit to detect mitochondrial membrane potential. Animal models of myocardial infarction were established. One week after modeling, bone marrow mesenchymal stem cel s were given via multi-point injection around the infarct zone of rats. Two weeks after modeling, heart tissues of rats were taken and sliced fol owed by DiI staining to calculate the survival rate of bone marrow mesenchymal stem cel s. Additional y, rat cardiac function was assessed by echocardiography prior to and after modeling as wel as at 4 weeks after cel transplantation. RESULTS AND CONCLUSION:At 12 hours after HPC, the expression of Pim-1, p-Akt and Bcl-2 gene in the infarct region was significantly increased, but the expression of caspase-3 and Bax was significantly decreased. Compared with the control group, cel viability in the 12-hour HPC group was increased very significantly at 1 week after cel transplantation (P<0.001), the migration and anti-apoptosis ability were enhanced significantly (P<0.01) and the cardiac function of rats was significantly improved in the 12-hour HPC group (P<0.05). Al of these protective effects were blocked by the Pim-1 inhibitor. These findings indicate that HPC can protect bone marrow mesenchymal stem cel s from apoptosis through activating Akt and up-regulating Pim-1, and thereby improve the therapeutic effect of bone marrow mesenchymal stem cel transplantation on ischemic heart diseases.
