OBJECTIVE To analyze the quantity transfer rule in the processing of Astragalus membranaceus before and after moistening-soaking and steaming-soaking followed by cutting. METHODS Three batches of A. membranaceus decoction pieces processed through moistening-soaking and steaming-soaking followed by cutting were prepared. The HPLC overlapping fingerprints of A. membranaceus and its decoction pieces were established through the Similarity Evaluation System of Chromatographic Fingerprints of TCM （2012 edition）. Combined with the previous qualitative analysis results， the common peaks were identified， the changes of common peak area were analyzed， and the principal component analysis was carried out. The contents of calycosin-7-glucoside， astragaloside Ⅰ and astragaloside Ⅳ in A. membranaceus and its decoction pieces were determined by HPLC， and the content differences of each component in different samples were compared. RESULTS The results of fingerprint analysis showed that 17 common peaks were identified. After steaming-soaking and moistening-soaking of A. membranaceus， the proportion of common peak area in the decoction pieces changed compared with the original medicine （for example， in A. membranaceus steaming-soaking decoction pieces， the proportion of peak area of malonyl calycosin-7-glucoside and malonyl astragaloside Ⅰ decreased， while the proportion of peak area of calycosin-7-glucoside increased）. The results of principal component analysis showed that A. membranaceus， and its decoction pieces after moistening-soaking and steaming-soaking followed by cutting were all clustered into one category respectively. The results of content determination showed that， compared with A. membranaceus， the average content of calycosin-7-glucoside in A. membranaceus moistening-soaking decoction pieces was significantly reduced （P＜0.05）； the average contents of calycosin-7-glucoside and astragaloside Ⅳ in A. membranaceus steaming- soaking decoction pieces were significantly increased （P＜0.05）； there was no significant difference in the average content of astragaloside Ⅳ in A. membranaceus moistening-soaking decoction pieces and astragaloside Ⅰ in the two decoction pieces （P＞ 0.05）. CONCLUSIONS There are differences in the quantity transfer rules of A. membranaceus before and after moistening-soaking and steaming-soaking followed by cutting. Steaming-soaking followed by cutting may make the transformation of unstable components （such as malonyl calycosin-7-glucoside and malonyl astragaloside Ⅰ） more complete.

Objective:To evaluate direct and indirect costs for schizophrenia,major depressive disorder(MDD)and bipolar disorder,and to compare their differences of cost composition,and to explore the drivers of the total costs.Methods:A total of 3 175 inpatients with schizophrenia,MDD,and bipolar disorder were recruited.In-patient's self-report total direct of medical costs outpatient and inpatient,out-of-pocket costs,and direct non-medical costs were regarded as direct costs.Productivity loss and other loss caused by damaging properties were defined as indirect costs.The perspectives of this study included individual and societal levels.Multivariate regression analysis was applied for detecting the factors influencing disease costs.Results:The total cost of schizophrenia was higher than those of MDD and bipolar disorder at individual and societal levels.The indirect costs of three mental disorders were higher than the direct costs,and the indirect cost ratio of bipolar disorder was higher than those of schizophre-nia and MDD.Age,gender,working condition and marital status(P＜0.05)were the important drivers of total costs.Conclusion:The economic burden of the three mental disorders is relatively heavy.Schizophrenia has heaviest disease burden,and the productivity loss due to mental disorders is the driving force of the soaring disease cost

Objective:To explore the clinical characteristics and related socio-demographic factors of schizo-phrenia patients with different ages of onset.Methods:Totally 2 016 patients with schizophrenia aged 15 to 70 were selected according to the diagnostic criteria for schizophrenia in the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition.All of the patients were interviewed by psychiatrists using the Mini International Neuropsy-chiatric Interview to diagnose schizophrenia,Clinical-Rated Dimensions of Psychosis Symptom Severity(CRDPSS)and the Positive and Negative Syndrome Scale(PANSS)to assess symptoms.The cut-off points were 18 and 25 years old for three age groups,i.e.early onset(EOS),youth onset(YOS)and adult onset(AOS).Statistical analy-ses were performed by analysis of variance Pearson correlation analysis,and multivariate linear regression.Results:The early-onset patients had the highest total PANSS score(73.8±28.0)and CRDPSS score(11.7±5.4).Fe-male gender,high education level,Han ethnicity,early onset age,and slower onset of illness were negatively corre-lated with the total and dimension score of PANSS scale and CRDPSS scale(standardized regression coefficient:0.04-0.47),and income level and smoking were negatively correlated with those score(standardized regression coefficient:-0.04--0.14).Conclusion:Early-onset schizophrenia patients have more severe symptoms,and fe-male,high education level,early-onset disease,and chronic onset are the risk factors of symptom severity in patients with schizophrenia.

Objective To explore the relationship between serum Visfatin,pentraxin 3(PTX3),and carbo-hydrate antigen 19-9(CA19-9)levels and prognosis in patients with acute cholecystitis.Methods A total of 228 patients with acute cholecystitis admitted to a hospital from September 2020 to September 2023 were se-lected as the study objects.According to the severity of the patients,228 patients were divided into mild group(n=81),moderate group(n=102)and severe group(n=45).The patients were divided into good prognosis group(n=186)and bad prognosis group(n=42).General data of patients were collected,serum Visfatin and PTX3 levels were detected by enzyme linked immunosorbent assay,and serum CA19-9 levels were determined by chemiluminescence immunoassay.Univariate and multivariate analysis of prognostic factors in patients with acute cholecystitis was performed,and the diagnostic value of serum Visfatin,PTX3 and CA19-9 levels in patients with acute cholecystitis was analyzed by drawing receiver operating characteristic curve.Results Ser-um Visfatin,PTX3 and CA19-9 in moderate and severe groups were significantly different from those in mild group(P＜0.05).There were significant differences in serum Visfatin,PTX3 and CA19-9 between severe group and moderate group(P＜0.05).Gallbladder thickness,long diameter and short diameter of gallbladder,serum Visfatin,PTX3 and CA19-9 levels in the poor prognosis group were significantly different from those in the good prognosis group(P＜0.05).Multivariate Logistic regression analysis showed that serum Visfatin,PTX3 and CA19-9 levels were the influential factors for poor prognosis of patients(P＜0.05).The area under the curve of serum Visfatin,PTX3 and CA19-9 combined diagnosis was significantly larger than that of Visfa-tin alone diagnosis(Z=4.577,P＜0.001)and PTX3 alone diagnosis(Z=3.132,P=0.002)and the area un-der the curve of CA19-9 diagnosis alone(Z=2.766,P=0.006).Conclusion Serum Visfatin,PTX3 and CA19-9 are elevated in patients with acute cholecystitis,which is related to the patient's condition.The combi-nation of the three is of better value in the diagnosis of poor prognosis.

Objective:To explore the application of biomechanics principle in the repair of double eyelid disappearance after blepharoplasty.Methods:A retrospective analysis was performed on 47 patients (46 females and 1 male) with double eyelid disappearance after blepharoplasty in the Department of Plastic and Cosmetic Surgery, Friendship Plastic Surgical Hospital from July 2018 to December 2022. The patients aged from 19-42 (28±8) years. The repair surgery was performed by increasing the mechanical factors that promoted the double eyelid formation or weakening the mechanical factors that inhibited the double eyelid formation. The overall satisfaction with ocular appearance, and psychological well-being and social function were evaluated with the Face-Q qustionnaires before or after operation.Results:By following-up for 3-24 months, the morphology of upper eyelids in all 47 patients were remarkably improved. 2 patients complained about asymmetry and 1 patient had multiple creases, for whom satisfactory results achieved after re-operation. The remaining patients presented smooth natural double eyelid line, and concave groove deformity when eyes closed were not noticed. The operative effects were satisfactory. After surgery, the scores for ocular satisfaction with facial appearance, psychological well-being and social function were (69.5±10.3), (75.5±13.6) and (68.3±11.3) scores, which were significantly increased than those before operation [(38.7±9.3), (54.8±10.5) and (52.3±8.7) scores], respectively (all P<0.05). Conclusion:More effective and reliable operation results can be obtained in the repair strategies of double eyelid disappearance after blepharoplasty by utilizing the biomechanical mechanism.

Objective:To investigate the surgical treatment methods of femoral artery pseudoaneurysm combined with infectious wounds and to evaluate the clinical effects.Methods:The retrospective observational research method was used. Twelve patients with femoral artery pseudoaneurysm combined with infectious wounds who met the inclusion criteria were admitted to Nanjing University of Chinese Medicine Wuxi Integrated Traditional Chinese and Western Medicine Hospital (Affiliated Hospital of Jiangnan University) from October 2014 to September 2022, including 6 males and 6 females, aged from 46 to 78 years. In the primary operation, debridement, tumor resection, and artery suture/venous grafting to repair the artery/artery ligation were performed, and the wound area after tumor resection ranged from 4.0 cm×1.5 cm to 12.0 cm×6.5 cm. Wounds that could be sutured were treated with tension reduction suture and extracutaneous continuous vacuum sealing drainage (VSD), while large wounds that could not be sutured were treated with VSD to control infection. In the secondary operation, tension reduction suture was performed to repair the wounds that could be sutured; large wounds were repaired with adjacent translocated flaps with area of 9.0 cm×5.0 cm to 15.0 cm×7.0 cm. Additionally, when the length of the exposed femoral artery was equal to or over 3.0 cm, the wounds were repaired with additional rectus femoris muscle flap with length of 15.0 to 18.0 cm. The donor areas of the flaps were directly sutured. The wound with artery ligation was treated with stamp skin grafting and continuous VSD. The bacterial culture results of the wound exudate samples on admission were recorded. The intraoperative blood loss, the location of femoral artery rupture, the artery treatment method, and the wound repair method in the primary operation were recorded, and the durations of catheter lavage, catheter drainage, and VSD treatment, and the drainage volume after the operation were recorded. The repair method of wounds in the secondary operation, the durations of catheter drainage and VSD treatment, and the total drainage volume after the operation were recorded. The survivals of flap/muscle flap/stamp skin grafts were observed, and the wound healing time was recorded. Follow-up after discharge was performed to evaluate the quality of wound healing and the walking function and to check whether the pulsatile mass disappeared. B-ultrasound or computed tomography angiography (CTA) was performed again to observe potential pseudoaneurysm recurrence and evaluate the patency of blood flow of the femoral artery.Results:The bacterial culture results of wound exudate samples of all the patients were positive on admission. The blood loss was 150 to 750 mL in the primary operation. The arterial ruptures were located in the femoral artery in 8 cases, in the external iliac artery in 2 cases, and in the femoral arteriovenous fistula in 2 cases. Six cases received direct artery suture, 4 cases received autologous great saphenous vein grafting to repair the artery, 1 case received autologous great saphenous vein bypass surgery, and 1 case received artery ligation. The primary wound suture was performed in 4 cases, along with catheter lavage for 3 to 5 days, catheter drainage for 4 to 6 days, VSD treatment for 5 to 7 days, and a total drainage volume of 80 to 450 mL after the surgery. In the secondary operation, the wounds were sutured directly in 3 cases along with catheter drainage for 2 to 3 days, the wound was repaired with scalp stamp skin graft and VSD treatment for 5 days in 1 case, the wounds were repaired with adjacent translocated flaps in 2 cases with catheter drainage for 2 to 3 days, and the wounds were repaired with rectus femoris muscle flaps+adjacent translocated flaps in 2 cases with catheter drainage for 3 to 5 days . The total drainage volume after the secondary operation ranged from 150 to 400 mL. All the skin flaps/muscle flaps/skin grafts survived after operation. The wound healing time ranged from 15 to 36 days after the primary operation. Follow-up of 2 to 8 months after discharge showed that the wounds of all patients healed well. One patient who underwent femoral artery ligation had calf amputation due to foot ischemic necrosis, and the rest of the patients regained normal walking ability. The pulsatile mass disappeared in inguinal region of all patients. B-ultrasound or CTA re-examination in 6 patients showed that the blood flow of femoral artery had good patency, and there was no pseudoaneurysm recurrence.Conclusions:Early debridement, tumor resection, and individualized artery treatment should be performed in patients with femoral artery pseudoaneurysm combined with infected wounds. Besides, proper drainage and personalized repair strategy should be conducted according to the wound condition to achieve a good outcome.

Objective:To investigate the role of SUMO E3 ligase ZNF451 in DNA damage repair and explore the underlying mechanism in non-small cell lung cancer A549 cells and cervical cancer HeLa cells.Methods:A549 cells and HeLa cells were irradiated with γ-ray irradiation or treated with etoposide. Cell proliferation viability was detected by the cell counting kit-8 assay. Protein expression was detected by Western blot assay. DNA damage repair level was detected by DR-GFP plasmid system, and the spatial positioning was detected by immunofluorescence.Results:Etoposide decreased the expression level of ZNF451 in a dose- and time- dependent manner. After treatment with 30, 50, 80 μmol/L etoposide, the cell viability were reduced after the knockdown of ZNF451 in A549 and HeLa cells(A549: t = 27.62, 25.61, 5.32, P<0.01; HeLa: t = 30.77, 21.28, 4.18, P<0.01). Furthermore, ZNF451 was recruited at DNA damage sites. A co-localization and endogenous interaction were found between ZNF451 and γ-H2AX after the treatment of irradiation or etoposide. Moreover, the expression level of γ-H2AX was significantly increased after treatment with 30, 50, 80 μmol/L etoposide(A549: t = 6.12, 10.67, 4.68, P<0.01; HeLa: t = 7.94, 9.81, 15.12, P<0.01)and the repair efficiency of NHEJ was reduced in ZNF451 knockdown cells( t = 18.60, P<0.05). Finally, the immunofluorescence assay showed that ZNF451 was co-localizated with 53BP1 and MDC1 after irradiation or etoposide treatment. Conclusions:Knockdown of ZNF451 inhibits cell proliferation and increases the level of DNA damage in A549 and HeLa cells. ZNF451 was recruited to DNA damage sites after DSBs and participated in NHEJ repair by co-localizing with DNA damage repair factor 53BP1/MDC1.

Objective:To investigate the effect of eyebrow arch augmentation with personalized polyether ether ketone (PEEK) implant assisted by endoscope.Methods:From January 2019 to August 2021, 9 patients with low and flat eyebrow arch requiring eyebrow arch augmentation were treated in the plastic surgery department of the Friendship Plastic Surgery Hospital Affiliated to Nanjing Medical University. The cranial and maxillofacial CT scanning data were obtained before operation, the eyebrow arch elevation range and height were designed according to the patient's requirements, and personalized peek implants were manufactured. During the operation, a small temporal hairline incision was used to accurately separate the implantation cavity of individualized peek implants under the periosteum of the eyebrow arch implantation area with the aid of endoscope. Personalized PEEK implants were implanted under endoscope to make them fully fit with the eyebrow arch bone and fixed with titanium nails. Photos were taken and analyzed before and after operation.Results:All patients were followed up for 3 months to 2 years. Their facial expressions were normal, and there were no motor nerve injury, rejection and iatrogenic infection. The patients were satisfied with the postoperative effect. Compared with before operation, the low level of orbital bone in eyebrow area was improved, and the facial contour was three-dimensional and harmonious.Conclusions:The eyebrow arch augmentation with individualized peek implant assisted by endoscope is safe and effective. It can greatly reshape the upper contour of the face, deepen the upper eyelid fossa and improve the convex eye phenomenon, so as to achieve the cosmetic effect of enhancing the three-dimensional sense of the eyebrow orbital area, which is worthy of clinical application.

Objective:To systematically evaluate the efficacy and safety of obinutuzumab-based regimen versus rituximab-based regimen in treatment of B-cell non-Hodgkin lymphoma (B-NHL).Methods:The Cochrane clinical controlled trials database, PubMed, Embase, American Society of Hematology meeting proceedings, American Society of Clinical Oncology annual meeting proceedings and ClinicalTrails database were searched for studies on the use of regimens containing obinutuzumab or rituximab for the treatment of B-NHL. Patients were divided into obinutuzumab group and rituximab group according to their medication status. Review Manager 5.3 software was used to compare the efficacy and safety of the two groups.Results:A total of 7 randomized controlled trials were selected, including 4 235 patients (1 430 cases of follicular lymphoma, 2 102 cases of diffuse large B-cell lymphoma, and 703 cases of other B-NHL); 2 121 cases were in the obinutuzumab group and 2 114 cases were in the rituximab group. Among 4 162 patients who could be evaluated, the objective response rate (ORR) in the obinutuzumab group was higher than that in the rituximab group [75.1% (1 565/2 083) vs. 72.7% (1 512/2 079); OR = 1.19, 95% CI 1.01-1.41, P = 0.03]. Progression-free survival (PFS) in the obinutuzumab group was better than that in the rituximab group ( HR = 0.86, 95% CI 0.75-0.99, P = 0.03). Among 3 542 patients who could be evaluated for adverse reactions, the incidence of grade 3-4 adverse reactions in the otuzumab group was higher than that in the rituximab group [61.8% (1 098/ 1 776) vs. 54.2% (958/1 766); OR = 1.50, 95% CI 1.29-1.74, P < 0.001], the incidence of grade 3-4 infusive-related adverse reactions [7.5% (158/1 776) vs. 3.1% (65/1 766); OR = 2.56, 95% CI 1.91-3.45, P < 0.001] and neutropenia [34.1% (597/1 749) vs. 29.4% (511/1 738); OR = 1.27, 95% CI 1.09-1.47, P = 0.002] in the obinutuzumab group were higher than those in the rituximab group. Conclusions:The ORR and PFS of B-NHL patients treated with obinutuzumab-based regimen are better than those treated with rituximab-based regimen, but the influence of adverse reactions should be considered when selecting the regimen.

Objective : To investigate the effect of Brigatinib on radiation sensitivity of colorectal cancer LOVO cells by treating colorectal cancer LOVO cells with a combination of radiation and brigatinib. Methods : Western blot and immunofluorescence detection were used to detect the amount of epidermal growth factor receptor(EGFR) , p ⁃ EGFR expression in colorectal cancer cells after treatment with different irradiation doses. The expression levels of EGFR , p ⁃EGFR , γ⁃H2AX , cleaved caspase⁃3 , cleaved caspase⁃7 and cleaved caspase⁃9 in LOVO cells were determined by Western blot , the levels of Non⁃homologous End Joining⁃NHEJ were detected by DR⁃GFP plasmid system , cell viability was detected by CCK⁃8 and apoptosis was detected by annexinv FITC / PI double labeling. Results : Radiation treatment significantly increased EGFR phosphorylation in LOVO cells , which was inhibited in a dose⁃dependent manner after treatment with Brigatinib. Non⁃homologous End Joining repair was inhibited following Brigatinib treatment , and a significant increase in apoptosis was observed in LOVO cells treated with combined Brigatinib and radiation. Conclusion Brigatinib inhibited non homologous end joining repair and promoted apoptosis in LOVO cells by inhibiting EGFR phosphorylation , which eventually increased the radiation sensitivity of LOVO cells.
