Objective The existing evidence of exercise rehabilitation in patients undergoing surgery for valvular heart disease was analyzed,described and evaluated by using evidence mapping methods.Methods Systematic reviews and randomized controlled trials on exercise rehabilitation of patients undergoing valvular heart disease surgery were searched from CNKI,Wanfang Data,VIP,CBM,Embase,PubMed,Cochrane Library,Web of Science,Ovid,CINAHL and other databases,and the search period was established until April 23,2024.The quality of the included literature was evaluated,and the feature information of the included literature was visualized in the form of bubble map and table.Results Fifty-one literatures(including 44 randomized controlled trials and 7 systematic evaluations)were finally included.Among the 44 randomized controlled trials,the types of exercise were mainly related to anaerobic exercise(3 literatures),aerobic exercise(11 literatures),flexibility training(8 literatures),and multisport exercise(22 literatures);postoperative inpatient rehabilitation accounted for a relatively high proportion(16 literatures),followed by overall postoperative rehabilitation(13 literatures)and pre-operative prehabilitation(7 literatures).Twenty-seven conclusions were categorized as"beneficial",15 as"possibly beneficial,"and one ach as"unclear"and"no effect".Seven systematic evaluations were subjected to Meta-analysis,and in terms of the design of the included studies,there were only 3 systematic reviews that included randomized controlled trials.Of the study conclusions,three were"beneficial",three were"possibly beneficial"and one was"unclear".Conclusion The evidence mapping shows that exercise rehabilitation is generally beneficial or potentially beneficial in the rehabilitation of valvular heart disease surgery,mainly in the postoperative inpatient rehabilitation phase.High-quality studies are needed to further investigate the effectiveness of exercise programs with different intensities,frequencies,and durations,as well as different valve types,adverse effects of exercise,and other outcome indicators.

Objective To systematically review the efficacy of enhanced recovery after surgery(ERAS)nursing on patients with dissection of aorta.Methods Nine databases,including PubMed,CNKI,etc were searched to identify randomized controlled trials involving dissection of aorta patients undergoing ERAS nursing.The retrieval time was from setting up of the databases until March 2024.Literature quality assessment followed by"Cochrane handbook for systematic reviews of interventions.Version 5.1.0",and Meta-analysis was conducted utilizing software of RevMan 5.4.Results Nine literatures with a total of 723 patients were included.The results of Meta-analysis showed that compared with the conventional nursing model,the application of ERAS nursing model could effectively promote the process of patients'postoperative recovery,and there were significant differences in indicators such as the time of postoperative mechanical ventilation,the time of the first postoperative out-of-bed activity,the time of tubing removal,the incidence of complications,the length of hospital stay,and the degree of perceived pain(P＜0.05).Conclusion Implementing nursing model based on ERAS on dissection of aorta patients can effectively enhance patients'postoperative recovery outcomes,thus worth clinical promotion and application.

Objective To evaluate the effect of mindfulness-based intervention in patients after percutaneous coronary intervention(PCI)through Meta-analysis.Methods Nine databases,including CNKI and PubMed,were searched for randomized controlled trials on the effect of mindfulness intervention in patients after PCI,and the search period was from the establishment of the database to May 31,2024.Two researchers independently screened the literature,extracted data and evaluated the quality,and used Revman 5.4 software for Meta-analysis.Results A total of 11 randomized controlled trials involving 998 patients were included.The results of Meta-analysis showed that compared with conventional care,the use of mindfulness-based intervention therapy could positively improve patients'postoperative anxiety,perceived stress level,mindfulness awareness and other indicators.In terms of safety measures,the incidence of cardiac adverse events was not statistically significant compared with usual care(P＞0.05).Conclusion Mindfulness intervention has a significant effect in patients after PCI.

AIM:To investigate the effect of vaccarin(VAC)on endothelial dysfunction in type 2 diabetes mellitus(T2DM),and to uncover the underlying mechanisms.METHODS:(1)C57BL/6 mice received intraperitoneal injection of streptozotocin and were fed with a high-fat diet(21.8 kJ/kg,60%of the energy source was fat)to construct a T2DM mouse model.Thirty mice were randomly divided into control,T2DM and T2DM+VAC groups,with 10 mice in each group.The mice in T2DM+VAC group were given 1 mg/kg VAC via oral gavage for 6 weeks,while those in control and T2DM groups were given the same volume of PBS.The mRNA and protein expression levels of BCL2-interacting pro-tein 3(BNIP3),PTEN-induced kinase 1(PINK1)and parkin in the thoracic aorta were detected by RT-qPCR and West-ern blot.(2)Human umbilical vein endothelial cells(HUVECs)were stimulated by high glucose(HG;35 mmol/L glu-cose).Mitochondrial membrane potential,autophagy and mitochondrial superoxide levels were detected using JC-1,acri-dine orange(AO)and MitoSOX staining,respectively.RESULTS:Compared with control group,the mRNA and protein levels of BNIP3,PINK1 and parkin were significantly increased in the thoracic aorta of T2DM mice(P<0.05).Compared with T2DM group,the mRNA and protein levels of BNIP3,PINK1 and parkin in the thoracic aorta were significantly re-duced in T2DM+VAC group(P<0.05).The results of JC-1,AO and MitoSOX staining showed that VAC attenuated the decrease in mitochondrial membrane potential and the increase in autophagy and mitochondrial superoxide levels in HG-in-duced HUVECs.Treatment with VAC also inhibited HG-mediated mitochondrial damage in HUVECs after BNIP3 overex-pression.The effect of miR-570-3p mimic on mitochondrial damage was similar to VAC.RT-qPCR and Western blot showed that both miR-570-3p mimic and VAC significantly reduced the mRNA and protein levels of BNIP3,PINK1 and parkin.In contrast,inhibition of miR-570-3p exhibited the opposite effects.CONCLUSION:Treatment with VAC alle-viated endothelial dysfunction in T2DM by inhibiting HG-induced mitochondrial dysfunction through miR-570-3p/BNIP3.

Objective:Quantified MRCP imaging data was used as a reference for design and preparation of a modified percutaneous transhepatic cholangio drainage (PTCD) tube.Methods:3.0 T upper abdominal MR and MRCP imaging data of 2 300 patients treated from July 2015 to July 2020 at the Department of Radiology of the Affiliated Cancer Hospital of Zhengzhou University were screened and a total of 381 patients diagnosed with biliary duct structures were identified. Causative etiologies among these patients included pancreatic adenocarcinoma (pancreatic head), cholangiocarcinoma, ampullary carcinoma, as well as intrahepatic and/or extrahepatic bile duct dilation. An improved PTCD tube was designed based on MRCP quantification of left and right hepatic and common hepatic duct length.Results:In the setting of biliary obstruction caused by malignancy, the distance of the left hepatic duct from its origin to the point of left and right hepatic duct confluence was 15.9±3.8 mm, while the distance of the right hepatic duct from its origin to the point of left and right hepatic duct confluence was 12.4±3.2 mm; the length of the bile duct from its origin to the point of left and right hepatic duct confluence was 34.0±8.1 mm. The improved PTCD tube design incorporated an altered length of the drainage orifice.Conclusion:MRCP imaging of the biliary tract is effective for measuring biliary tract length in the setting of pathological dilation. Based on our biliary tract measurements, a modified PTCD tube was designed to more effectively meet drainage requirements and manage biliary obstruction caused by Bismuth-Corlette type Ⅱ and Ⅲ malignancies.

Objective:To investigate the precautions and clinical effects of minimally invasive lateral bone transfer of tibia in the treatment of diabetic foot.Methods:A retrospective analysis was performed on 82 patients with diabetic foot admitted to the Trauma Department of Changzhou First People's Hospital from January 2019 to December 2022. According to the Wagner grade of diabetic foot, there were 12 cases of grade 2, 50 cases of grade 3, and 20 cases of grade 4. According to the surgical method, 45 patients were divided into bone transfer group. There were 29 males and 16 females, with an average age of 65.27±10.74 years (ranging from 44-87 years), who underwent minimally invasive bone transfer of tibia combined with local debridement treatment. In the non-bone transfer group, there were 37 cases (26 males and 11 females) with an average age of 66.05±11.08 years (ranging from 44 to 86 years), who were treated with local debridement. Gender, age, Wagner grade, surface temperature difference of the affected limb, visual analogue scale (VAS) score of the affected limb before and 1 month after surgery, wound healing rate 1 month after surgery, and recurrence rate of the affected foot 1 year after surgery were compared between the two groups. Outcomes of the cases of different Wagner grades were compared.Result:All 82 patients were followed up for 14.23±1.20 months. There was no significant difference in gender, age, Wagner grade and preoperative VAS between the two groups ( P>0.05). The skin temperature of the affected limb before and after surgery in the bone transfer group was significantly higher than that in the non-bone transfer group 1.93±0.31 ℃ ( P<0.05), and the VAS of the bone transfer group was 2.18±0.58 points 1 month after surgery, which was lower than that in the non-bone transfer group of 5.41±0.93. The VAS difference before and after surgery in the bone transfer group was 4.80±1.24 points, which was greater than that in the non-bone transfer group of 1.62±1.48 points with significant difference ( P<0.05). The wound healing rate was over 98.78%±2.17% in the bone transfer group and 52.57%±6.41% in the non-bone transfer group one month after surgery. No recurrence or recurrence was found in the bone transfer group one year after surgery, and the recurrence rate was 86% (32/37) in the non-bone transfer group with significant difference ( P<0.05). There was no difference in preoperative VAS for different grades of diabetic foot (grades 2, 3, and 4). There were significant differences in VAS, VAS decrease, postoperative limb surface temperature increase, local wound healing rate at 1 month, and lower limb ulcer recurrence or recurrence rate at 12 months in the bone transfer groups of Wagner grade 2, 3, and 4 ( P<0.05). Conclusion:Minimally invasive lateral bone transfer of tibia combined with local precision debridement could significantly increase the healing rate of diabetic foot ulcer, improve the peripheral microcirculation of the affected limb, reduce the pain of the affected limb, and decrease the recurrence rate of diabetic foot ulcer.

Objective:To determine the expression of transmembrane protein 45A (TMEM45A) in keloid tissues and fibroblasts, and to evaluate its effect on extracellular matrix (ECM) synthesis by keloid-derived fibroblasts (KFs) .Methods:Samples of surgically excised keloid and normal foreskin tissues were collected from the Department of Dermatology and Department of Urology of Yanbian University Hospital from January 2019 to December 2020, and TMEM45A protein expression was determined in keloid tissues and KFs by Western blot analysis. KFs were divided into TMEM45A-specific small interfering RNA (siRNA) group and control siRNA group to be transfected with the TMEM45A-specific siRNA and control siRNA respectively. Then, Western blot analysis was performed to evaluate the effects of down-regulation of the TMEM45A gene on the expression of myofibroblast marker protein (α-smooth muscle actin) and ECM-related proteins.Results:Compared with normal skin tissues (1.00 ± 0.11) and fibroblasts (1.00 ± 0.20), TMEM45A expression levels significantly decreased in keloid tissues (0.26 ± 0.05) and KFs (0.41 ± 0.09), respectively ( t = 10.76, 4.75, P < 0.001, = 0.009, respectively). The expression levels of α-smooth muscle actin, ECM-related type Ⅰ collagen, type Ⅲ collagen, and fibronectin were significantly higher in the TMEM45A-specific siRNA group than in the control siRNA group ( t = -5.98, -4.57, -4.90, -7.19, P = 0.004, 0.010, 0.008, 0.002, respectively) . Conclusion:Lowly expressed TMEM45A in keloids may play an important role in the pathogenesis of keloids by promoting ECM synthesis.

Objective:To compare the toxicity and prognosis of patients with stage Ⅲ cervical cancer treated using different regimens.Methods:A retrospective analysis was carried out for 194 patients with stage Ⅲ cervical cancer determined according to the revised 2018 International Federation of Gynecology and Obstetrics staging system (16 cases of stage Ⅲ A, 23 cases of stage Ⅲ B, 136 cases of stage Ⅲ C1, and 19 cases of stage Ⅲ C2) admitted to the First Affiliated Hospital of Soochow University from January 2010 to December 2020. They were divided into a radical radiotherapy±chemotherapy group (81 cases) and a radical hysterectomy + radiotherapy±chemotherapy group (113 cases) according to different treatment method. The difference in toxicity between the two groups was determined using the χ2 test. The survival curves and progression-free survival curves were plotted using the Kaplan-Meier method, and the Log rank test was also performed. The differences in toxicity and prognosis were further analyzed in 136 patients with stage Ⅲ C1 cervical cancer result patients in the radical radiotherapy±chemotherapy group were more likely to have hemoglobin decline ( χ2=10.68, P=0.004), rectal mucositis ( χ2=14.41, P=0.001), and vaginal fistula ( χ2=7.16, P=0.012) of grades 3 and 4. Patients in the radical hysterectomy+ radiotherapy±chemotherapy group were more likely to have increased aspartate aminotransferase ( χ2=10.96, P=0.002) and alanine aminotransferase ( χ2=8.49, P=0.010). The differences were statistically significant. The 5-year progression-free survival rate of the radical radiotherapy±chemotherapy group was 58.3%, which was lower than that of the radical hysterectomy + radiotherapy±chemotherapy group (74.5%; χ2=5.33, P=0.021). Among the 136 patients with stage Ⅲ C1 cervical cancer, the ones in the radical radiotherapy±chemotherapy group (34 cases) were more likely to develop rectal mucositis ( χ2=13.25, P=0.003), while the ones in the radical hysterectomy + radiotherapy±chemotherapy group (102 cases) were more likely to have elevated aspartate aminotransferase ( χ2=6.18, P=0.046). The differences were statistically significant. The 5-year survival rates of the radical radiotherapy±chemotherapy group and the radical hysterectomy+ radiotherapy±chemotherapy group were 85.5% and 86.3%, respectively. The difference was not statistically significant ( P=0.893). The 5-year progression-free survival rates of the radical radiotherapy±chemotherapy group and the radical hysterectomy + radiotherapy±chemotherapy group were 65.6% and 77.1%, respectively. The difference was not statistically significant ( P=0.244). Conclusions:For patients with stage Ⅲ cervical cancer, the ones in the radical radiotherapy±chemotherapy group were more likely to progress and have a poorer prognosis compared with the ones in the radical hysterectomy+ radiotherapy±chemotherapy group. For patients with stage Ⅲ C1 cervical cancer, there was no significant difference in the prognosis of patients between the groups. The two treatment method lead to different toxicity, with no obvious advantages and disadvantages. Considering the risks and economic burdens caused by surgery, radical radiotherapy and chemotherapy is recommended for patients with stage Ⅲ C1 cervical cancer.

The cases were staged according to the 2009 and 2018 FIGO staging, and the Kendall τb coefficient was calculated to compare the consistency of the distribution of the two stages. Kaplan-Meier was used for survival analysis, and log-rank test was used to test the difference of prognosis in each stage. Cox-regression was used to analyze the prognostic factors of cervical cancer patients.Results:In the 2009 FIGO edition of staging, 1 case of stage ⅠB1 was reduced to stage ⅠA1 due to the microscopic infiltration depth <5 mm, 51 cases of stage ⅠB1 were raised to stage ⅠB2 due to 2 cm4 cm. A total of 119 cases raised to stage ⅢC1 due to pelvic lymph node metastasis, and 11 cases raised to stage ⅢC2 due to para-aortic lymph node metastasis. The distribution of cases in the two stages was consistent (τb=0.61, P<0.001). There were statistically significant differences in overall survival (OS) ( χ2=107.13, P<0.001; χ2=93.02, P<0.001; χ2=92.74, P<0.001) and progression-free survival (PFS) ( χ2=91.95, P<0.001; χ2=77.69, P<0.001; χ2=73.27, P<0.001) among patients with different stages of FIGO in 2018 (ⅠA, ⅠB, Ⅱ, ⅢA, ⅢB, ⅢC1, ⅢC2, Ⅳ) and 2009 (ⅠA, ⅠB, Ⅱ, ⅢA, ⅢB, Ⅳ) and patients with different T stages (T 1, T 2, T 3, T 4).

According to the 2018 FIGO stage, the 5-year OS rates of patients with stage ⅡA and ⅡB were 95.7% and 75.6% respectively, with a statistically significant difference ( χ2=13.96, P<0.001). The 5-year PFS rates of patients with stage ⅡA and ⅡB were 83.1% and 67.1% respectively, with a statistically significant difference ( χ2=7.61, P=0.006). According to the 2009 FIGO stage, the 5-year OS rates of patients with stage ⅡA and ⅡB were 90.9% and 75.0% respectively, with a statistically significant difference ( χ2=8.85, P=0.003). The 5-year PFS rates of patients with stage ⅡA and ⅡB were 75.7% and 66.7% respectively, with a statistically significant difference ( χ2=4.07, P=0.044). For patients with 2018 FIGO stage Ⅱ, pathological type ( HR=20.28, 95% CI: 2.93-140.32, P=0.002) and stage ( HR=4.35, 95% CI: 1.02-18.55, P=0.047) were independent risks factors for OS. For patients with 2009 FIGO stage Ⅱ, pathological type ( HR=5.82, 95% CI: 1.62-20.94, P=0.007) was an independent risk factor for OS, and pathological type ( HR=3.09, 95% CI: 1.22-7.85, P=0.017) and lymph node metastasis ( HR=2.07, 95% CI: 1.22-3.51, P=0.007) were independent risk factors for PFS. For patients with 2018 FIGO stage Ⅲ, maximum tumor diameter ( HR=3.31, 95% CI: 1.45-7.56, P=0.005) and SCCA positive after treatment ( HR=4.67, 95% CI: 1.22-17.86, P=0.024) were independent risk factors for OS, and pathological type ( HR=4.15, 95% CI: 1.47-11.77, P=0.007) and SCCA positive after treatment ( HR=3.96, 95% CI: 1.45-10.86, P=0.007) were independent risk factors for PFS. Conclusion:The 2018 and 2009 FIGO staging have a good distribution consistency in the cervical cancer patients, and the 2018 FIGO stage ⅠB has more advantages in judging the prognosis, but stage ⅢC cannot accurately judge the prognosis. Lymph node metastasis and maximum tumor diameter are more important prognostic factors.

At present, the clinical judgment of cervical cancer prognosis is mainly based on common pathological factors, such as tumor size, lymph node metastasis, and the depth of interstitial invasion. In recent years, with the advancement of technology, many biomarkers have been proved to be closely related to the diagnosis and prognosis of cervical cancer. Hematological parameters and other medical diseases also affect the survival of cervical cancer patients to some extent.
