Objective To discuss left ventricular reconstruction methods and effectivness in patients with left ventricular aneurysm after myocardial infarction. Methods Between June 2003 and August 2008, 23 patients with left ventricular aneurysm after myocardial infarction were treated. Of them, 13 were male and 10 were female with an average age of 61.2 years (range, 47-74 years). According to New York Heart Association (NYHA) criteria for cardiac function, there were 3 cases of grade I, 6 cases of grade II, 10 cases of grade III, and 4 cases of grade IV. The coronary arteriongraphy showed singlevesseldisease in 2 cases, double-vessel disease in 5 cases, triple-vessel disease in 16 cases. The locations of ventricular aneurysm were the apex cordis in 18 cases, antetheca and parieslateral is in 4 cases, and interior wall in 1 case. The left ventricular ejection fraction was 36.52%± 12.15%, and left ventricular diastol ic final diameter was (62.30 ± 6.52 ) mm. Nine patients received standard l inear repair, 6 patients received standard l inear repair after endocardial ring shrinkage, and 8 patients received patch suture after endocardial ring shinkage. Results Two cases died perioperatively, and re-thoracotomy was performed to stop bleeding in 1 case. Incisions healed by first intention in the other patients without early compl ication. Twentyone patients were followed up 7-48 months (median, 19 months). At 6 months after surgery, the left ventricular ejection fraction 46.52% ± 9.41% were significanly improved when compared with that at preoperation (t=2.240, P=0.023); the left ventricular diastol ic final diameter (52.23 ± 5.11) mm were significantly decreased when compared with that at preoperation (t=2.170, P=0.035). The cardiac function according to NYHA criteria was at grade I in 8 cases and at grade II in 13 cases. One patient died of cerebral hemorrhage at 18 months after operation and the activities of daily l iving recoverd in the others. Conclusion Individual theraputic methods are used according to patients’ different conditions for left ventricular aneurysm after myocardial infarction.

Objective To evaluate the effect of day surgery with diagnosis-related groups (DRG) evaluation indicators. Methods The inpatients undergoing surgery in Beijing Tongren Hospital of Capital Medical University between March and September 2022 were enrolled in this study. The medical quality, medical efficiency, hospitalization cost, DRG insurance payment and other DRD-related indicators were retrospectively collected and compared between day surgery patients and non-day surgery patients, and the average length of hospital stay and hospitalization costs were compared between the two surgery modes within DRGs. Chi-square test was used for enumeration data, and t-test and Mann-Whitney U test were used for measurement data. Results A total of 29339 day surgery patients and 19019 non-day surgery patients were enrolled. In the day surgery group, the proportions of local patients (71.71% vs. 68.62%), routine discharge (99.93% vs. 99.78%), and class A incisions (99.92% vs. 99.55%) were better than those in the non-day surgery group (P<0.05), and the average length of hospital stay [(1.00±0.00) vs. (6.98±5.00) d] and the average hospitalization costs [(7306.62±4605.73) vs. (24913.97±24623.54) yuan] were lower than those in the non-day surgery group (P<0.05). The top 2 reduction of average length of hospital stay were in the CB49 group and CB39 group, decreasing by 87.45% and 86.24%, respectively. The top 2 reduction of hospitalization costs were in the DC19 group and CC15 group, decreasing by 84.15% and 73.61%, respectively. DRG payment balance of medical insurance in the day surgery group was higher than that in the non-day surgery group (22.95% vs. 5.98%). Conclusions Day surgery not only ensure the medical quality, but also shorten the length of hospital stay and reduce the burden of medical expenses. Day surgery can effectively improve the utilization efficiency of hospital bed resources, it is an effective measure to promote the high quality development of hospital and comply with DRG payment reform.
Objective To observe the therapeutic effects of photodynamic therapy（PDT）on choroidal neovascularization（CNV）with or without cystoid macular edema（CME）in patients with wet agerelated macular degeneration（AMD）. Methods The clinical data of 54 patients (54 eyes) with wet AMD who had undergone the standard PDT，including 16 patients（21 eyes）with CME and 28 patients（33 eyes）without CME were retrospectively analyzed. The visual acuity and BFT of patients were examined by early treatment diabetic retinopathy study (ETDRS) and optical coherence tomography（OCT）before and per three months after PDT. The follow up was 3-18 months with the mean of 8.3 months.Results At the last time of follow up, in CME group，ETDRS letter score was（29.429plusmn;17.907）and the BFT was （316.429plusmn;77.161）mu;m，compared with that before the treatment, the difference were statistically significant (t=-0.389，2.246；P＝0.701，0.019). In nonCME group, ETDRS letter score was (48.121plusmn;17.911) and the BFT was (244.667plusmn;37.619) mu;m, compared with that before the treatment, the difference were statistically significant (t=-3.424，6.880；P＝0.002，0.000). There were statistical significance for the change of ETDRS letter score and BFT between the two groups (t=-2.194，2.212；P＝0.033，0.031）). Conclusions Therapeutic effect of PDT on CNV with CME was better than without CME in patients with wet AMD.
ObjectiveTo review the research progress of adipose-derived stem cells (ADSCs) in skin scar prevention and treatment.MethodsThe related literature was extensively reviewed and analyzed. The recent in vitro and in vivo experiments and clinical studies on the role of ADSCs in skin scar prevention and treatment, and the possible mechanisms and biomaterials to optimize the effect of ADSCs were summarized.ResultsAs demonstrated by in vitro and in vivo experiments and clinical studies, ADSCs participate in the whole process of skin wound healing and may prevent and treat skin scars by reducing inflammation, promoting angiogenesis, or inhibiting (muscle) fibroblasts activity to reduce collagen deposition through the p38/mitogen-activated protein kinase, peroxisome proliferator activated receptor γ, transforming growth factor β1/Smads pathways. Moreover, bioengineered materials such as hydrogel from acellular porcine adipose tissue, porcine small-intestine submucosa, and poly (3-hydroxybutyrate-co-hydroxyvalerate) scaffold may further enhance the efficacy of ADSCs in preventing and treating skin scars.ConclusionRemarkable progress has been made in the application of ADSCs in skin scar prevention and treatment. While, further studies are still needed to explore the application methods of ADSCs in the clinic.
ObjectiveTo study the application of non-real-time ultrasound bronchoscopy combined with Metagenomic Next-Generation Sequencing (mNGS) for diagnosis in focal pulmonary infectious diseases. MethodsProspective inclusion of patients with focal pulmonary infection were randomly divided into two groups, the experimental group used non-real-time ultrasound bronchoscopy positioning to collect bronchial alveolar lavage fluid (BALF), while the control group used chest CT position. BALF was subjected to mNGS and traditional microbial detection including traditional culture, the fungal GM test and Xpert (MTB/RIF). ResultThe positive rate of traditional culture (39.58% vs. 16.67%, P=0.013) and mNGS (89.58% vs. 72.92%, P=0.036) in experimental group was higher. The positive rate of Xpert MTB/RIF (4.17% vs. 2.08%, P=1) and fungal GM test (6.25% vs. 4.17%, P=0.765) was similar. The positive rate of bacteria and fungi detected by mNGS was higher than traditional culture (61.46% vs. 28.13%, P<0.001). Mycobacterium tuberculosis was similar to Xpert MTB/RIF (8.33% vs. 3.13%, P=0.21). Aspergillus was similar to GM test (7.29% vs. 5.21%, P=0.77). The total positive rate of traditional microbial methods was 36.46%, but 81.25% in mNGS (P<0.001). mNGS showed that 35 cases were positive and 13 kinds of pathogens were detected in control group, but 43 patients and 17 kinds of pathogens were detected in experimental group. The average hospitalization time [(12.92±3.54) days vs. (16.35±7.49) days] and the cost [CNY (12209.17±3956.17) vs. CNY (19044.10±17350.85)] of experimental group was less (P<0.001). ConclusionsNon-real-time ultrasound bronchoscopy combined with mNGS can improve the diagnostic rate of focal pulmonary infectious diseases which is worthy of popularization and application in clinical practice.
ObjectiveTo explore the surgical technique and clinical effect of endoscopic assisted transaxillary breast tumor resection in the treatment of benign and malignant breast tumors. MethodsThe clinical data of 18 patients received endoscopic breast tumor resection from September 2020 to December 2021 in the Department of Breast Surgery, West China Hospital, Sichuan University, were retrospectively analyzed to evaluate the feasibility, tumor safety and postoperative cosmetic effect. There were 7 patients with benign breast tumors (a benign breast tumor group) and 11 patients with early breast cancer (a malignant breast tumor group). Breast-Q and Scar-Q questionnaires were used to evaluate postoperative quality of life and satisfaction of patients. ResultsEndoscopic breast tumor resection was performed successfully in 18 female patients, among whom 12 patients received day surgery. The mean age of benign and malignant breast tumor groups was 29.6±11.6 years and 46.7±14.3 years, the mean tumor size in pathological examination was 3.3±2.1 cm and 2.0±0.8 cm, and the operative time was 138.9±57.0 min and 177.3±46.3 min, respectively. One patient had positive resection margin and underwent intraoperative extended resection in the malignant breast tumor group. All the patients were successfully followed up, and the mean follow-up time of benign and malignant breast tumor groups was 6.8±4.0 months and 8.7±4.9 months, respectively. No complications or tumor recurrence occurred. The scores of psychosocial status, sexual well-being, chest wall status and breast satisfaction decreased one month after surgery and basically recovered to the preoperative level in one year, and the score of scar appearance increased to 64.6±5.9 points one year postoperatively. ConclusionEndoscopic assisted transaxillary breast tumor resection can effectively improve postoperative cosmetic effect and patient satisfaction on the premise of safety.
