Objective To study the clinical effect of levosimendan combined with recombinant human brain natriuretic peptide(rhBNP)on patients with acute heart failure.Methods A total of 100 patients with acute heart failure in the hospital from December 2019 to December 2021 were selected as the research sub-jects.According to different treatment options,the subjects were divided into the control group,levosimendan group,rhBNP group and combined treatment group,with 25 cases in each group.The control group received traditional conventional diuretic,tube expansion and other treatment;the levosimendan group was treated with levosimendan on the basis of the control group;the rhBNP group was treated with rhBNP on the basis of the control group;the combined treatment group was treated with levosimendan and rhBNP on the basis of the control group.The improvement of New York Heart Association(NYHA)classification,death,rehospitaliza-tion rate,6-minute walking distance,improvement of serological indicators and adverse reactions were recor-ded in each group.Results Before treatment,there was no significant difference in baseline data between the groups(P>0.05).On the 1 st and 3 rd day after treatment,the improvement of NYHA classification in the combined treatment group was better than that in the other groups(P<0.05),and the improvement of NY-HA classification in the levosimendan group and rhBNP group was better than that in the control group(P<0.05).The readmission rate within 6 months after treatment in the combined treatment group was lower than that in the other groups(P<0.05).At 5 and 9 days after treatment,the 6-minute walking distance in the combined treatment group was longer than that in the other groups(P<0.05).At 9 days after treatment,the left ventricular ejection fraction(LVEF)in the combined treatment group was higher than that in the other groups(P<0.05),and the level of N-terminal B-type natriuretic peptide(NT-proBNP)in the combined treatment group was lower than that in the other groups(P<0.05).No significant difference was found in the comparison of the occurrence of adverse reactions among the four groups(P>0.05).Conclusion The combina-tion of levosimendan and rhBNP in the treatment of patients with acute heart failure is superior to traditional treatment and monotherapy in early clinical improvement,and dose not increase the incidence of adverse reactions.

Objective:To describe and analyze suicide risk of patients with schizophrenia,major depressive disorder,and bipolar disorder.Methods:A total of 2 016 patients with schizophrenia,903 patients with major de-pressive disorder,and 381 patients with bipolar disorder from inpatients,clinics,or communities who met the diag-nostic criteria of the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition were recruited.All patients were interviewed by psychiatrists using the Mini International Neuropsychiatric Interview to diagnose mental disor-ders and assess suicide risk,as well as Clinical-Rated Dimensions of Psychosis Symptom Severity(CRDPSS)to as-sess symptoms.Differences and risk factors of suicide risk among three types of mental disorders were explored u-sing multivariate logistic regression analysis.Results:In the past one month,37 patients with schizophrenia(1.8％),516 patients with major depressive disorder(57.1％),and 102 patients with bipolar disorder(26.8％)had suicide risk.Compared with patients with schizophrenia,suicide risk in patients with major depressive disorder(OR=36.50)and bipolar disorder(OR=20.10)increased.Female(OR=1.87),smoking(OR=1.76),family history of suicide(OR=5.09),higher score of CRDPSS hallucination(OR=1.80),and higher score of CRDPSS depression(OR=1.54)were risk factors of suicide risk of patients.Conclusions:Suicide risk of patients with ma-jor depressive disorder and bipolar disorder is higher than that of patients with schizophrenia.In clinical practice,it is important to regularly assess suicide risk of patients.Patients who experience symptoms of hallucination and de-pression should be paid more attention to.

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 investigate the incidence of postoperative complications in Chinese patients with gastric or colorectal cancer, and to evaluate the risk factors for postoperative complications.Methods:This was a national, multicenter, prospective, registry-based, cohort study of data obtained from the database of the Prevalence of Abdominal Complications After Gastro- enterological Surgery (PACAGE) study sponsored by the China Gastrointestinal Cancer Surgical Union. The PACAGE database prospectively collected general demographic characteristics, protocols for perioperative treatment, and variables associated with postoperative complications in patients treated for gastric or colorectal cancer in 20 medical centers from December 2018 to December 2020. The patients were grouped according to the presence or absence of postoperative complications. Postoperative complications were categorized and graded in accordance with the expert consensus on postoperative complications in gastrointestinal oncology surgery and Clavien-Dindo grading criteria. The incidence of postoperative complications of different grades are presented as bar charts. Independent risk factors for occurrence of postoperative complications were identified by multifactorial unconditional logistic regression.Results:The study cohort comprised 3926 patients with gastric or colorectal cancer, 657 (16.7%) of whom had a total of 876 postoperative complications. Serious complications (Grade III and above) occurred in 4.0% of patients (156/3926). The rate of Grade V complications was 0.2% (7/3926). The cohort included 2271 patients with gastric cancer with a postoperative complication rate of 18.1% (412/2271) and serious complication rate of 4.7% (106/2271); and 1655 with colorectal cancer, with a postoperative complication rate of 14.8% (245/1655) and serious complication rate of 3.0% (50/1655). The incidences of anastomotic leakage in patients with gastric and colorectal cancer were 3.3% (74/2271) and 3.4% (56/1655), respectively. Abdominal infection was the most frequently occurring complication, accounting for 28.7% (164/572) and 39.5% (120/304) of postoperative complications in patients with gastric and colorectal cancer, respectively. The most frequently occurring grade of postoperative complication was Grade II, accounting for 65.4% (374/572) and 56.6% (172/304) of complications in patients with gastric and colorectal cancers, respectively. Multifactorial analysis identified (1) the following independent risk factors for postoperative complications in patients in the gastric cancer group: preoperative comorbidities (OR=2.54, 95%CI: 1.51-4.28, P<0.001), neoadjuvant therapy (OR=1.42, 95%CI:1.06-1.89, P=0.020), high American Society of Anesthesiologists (ASA) scores (ASA score 2 points:OR=1.60, 95% CI: 1.23-2.07, P<0.001, ASA score ≥3 points:OR=0.43, 95% CI: 0.25-0.73, P=0.002), operative time >180 minutes (OR=1.81, 95% CI: 1.42-2.31, P<0.001), intraoperative bleeding >50 mL (OR=1.29,95%CI: 1.01-1.63, P=0.038), and distal gastrectomy compared with total gastrectomy (OR=0.65,95%CI: 0.51-0.83, P<0.001); and (2) the following independent risk factors for postoperative complications in patients in the colorectal cancer group: female (OR=0.60, 95%CI: 0.44-0.80, P<0.001), preoperative comorbidities (OR=2.73, 95%CI: 1.25-5.99, P=0.030), neoadjuvant therapy (OR=1.83, 95%CI:1.23-2.72, P=0.008), laparoscopic surgery (OR=0.47, 95%CI: 0.30-0.72, P=0.022), and abdominoperineal resection compared with low anterior resection (OR=2.74, 95%CI: 1.71-4.41, P<0.001). Conclusion:Postoperative complications associated with various types of infection were the most frequent complications in patients with gastric or colorectal cancer. Although the risk factors for postoperative complications differed between patients with gastric cancer and those with colorectal cancer, the presence of preoperative comorbidities, administration of neoadjuvant therapy, and extent of surgical resection, were the commonest factors associated with postoperative complications in patients of both categories.

All patients were female. The mean age was 35.7 years (range, 25-51 years) and the mean body mass index was 20.3 (range, 16.8-24.3 kg/cm 2). The mean time after autologous fat transplantation was 53.4 months (range, 19-96 months). Postoperative patient satisfaction surveys were conducted, and 2 independent doctors evaluated clinical effect preoperative and postoperative photographs at 3-6 months postoperatively. Results:There were 29 cases (100%) underwent liposuction in the pre-zygomatic region, and the amount of fat was 4.1-12.6 (7.95±1.85) ml. There were 4 cases (13.8%) underwent liposuction in the forehead, and the amount of fat was 1.8-5.2 (2.75±0.50) ml. There were 7 cases (24.1%) underwent liposuction in the temporal region, and the amount of fat was 2.8-6.5 (3.86±1.07) ml. There were 8 cases (27.6%) underwent liposuction in the cheek, and the amount of fat was 5.2-10.5 (7.25±2.12) ml. There were 18 cases (62.1%) underwent liposuction in the perioral region, and the amount of fat was 3.7-9.5 (6.33±1.28) ml. The energy delivered by bipolar radiofrequency was 3.3-10.2 (5.71±2.27) KJ. 82.8% of patients were satisfied with their postoperative effect (24/29 patients). 86.2% of doctors were satisfied with the postoperative effect (25/29 patients). Two out of 29 patients (6.9%) developed irregularity by liposuction.Conclusions:Low negative pressure liposuction combined with bipolar radiofrequency can effectively reduce the fat, narrow the tissue gap and improve facial sagging, which is an effective method for repairing facial fat overfilling.

Objective:To explore the effect and safety of mesenchymal stem cell exosome microneedle introduction in the treatment of melasma.Methods:Thirty cases of female patients with stable melasma in the Department of Dermatology, Changsha Meilai Medical Beauty Hospital, aged (36±5) years and with a disease duration of (42.4±20.7) months, from July 2021 to July 2022, were retrospectively included. According to Fitzpatrick skin typing, 23 cases of type Ⅲ and 7 cases of type Ⅳ were included. All patients were locally anesthetized with lidocaine cream for 30 min, and rolled with a 0.5 mm needle in a zigzag pattern with even force, in the order of the right cheek, the left cheek, the forehead, the nose, the mandible, and the upper lip. During the rolling process, 3 ml of MSC exosome medical liquid wound dressing was applied to the facial skin, and after it was fully absorbed, exosome was locally readministered in the area of melasma. Treatment ended with a slight redness at the site of application. 1 MSC exosome wound dressing was appllied as a cold compress for 15 min after treatment. Treatment was given once every 2 weeks for 6 consecutive sessions. All the patients were followed up at 4 and 12 weeks after the last session, and the area and severity index of melasma (MASI) were scored before and after the treatment, the clinical efficiency and patient satisfaction rate and the incidence of adverse reactions were also counted.Results:At 4 and 12 weeks after the end of treatment, the skin color of all 30 patients was brighter than that before treatment, and no recurrence of melasma symptoms seen. At 12 weeks after the end of treatment, the decrease rate of MASI score was 66.1%, among which the decrease rate of MASI score in patients with type Ⅲ melasma was 63.9%, and the decrease rate of MASI score in patients with type Ⅳ melasma was 63.9%. Among the 30 patients, 1 case was cured, 25 cases showed obvious improved, 4 cases were improved, and no cases were ineffective, with an effective rate of 86.7% (26/30). Five patients were very satisfied, 18 patients were satisfied, 6 patients were generally satisfied, and 1 patient was dissatisfied; the patient satisfaction rate was 76.7% (23/30). No serious adverse reactions occurred in all patients.Conclusions:MSC exosome microneedle introduction is safe and effective in the treatment of melasma without serious adverse reactions.

Femoral neck fracture (FNF) in the elderly patients is currently a major health challenge worldwide, with excessive consumption of medical resources, high incidence of complications as well as suboptimal outcome and prognosis. Hip joint arthroplasty (HJA) has been the mainstream treatment for FNF in the elderly, but the conventional surgical approaches and techniques are still confronted with a series of bottlenecks such as dislocation, limp and limb length discrepancy. In recent years, direct anterior approach (DAA) for HJA (DAA-HJA) has been a major new choice in the field of joint replacement, which achieves improved clinical effectiveness of HJA in the treatment of elderly FNF, due to the fact that DAA approach involves the neuromuscular interface and accords with the idea of soft tissue retention and enhanced recovery after surgery. However, there is still a lack of unified understanding of standard technique and procedure of DAA-HJA in the treatment of elderly FNF. Therefore, relevant experts from the Hip Joint Group of Chinese Orthopedics Association of Chinese Medical Association, Youth Arthrology Group of Orthopedic Committee of PLA, Orthopedic Committee of Chongqing Medical Association, Branch of Orthopedic Surgeons of Chongqing Medical Doctor Association and Sport Medicine Committee of Chongqing Medical Association were organized to formulate the " Chinese expert consensus on the technical standard of direct anterior hip arthroplasty for elderly femoral neck fracture ( version 2023)" based on evidence-based medicine. This consensus mainly proposed 13 recommendations covering indications, surgical plans, prosthesis selections, surgical techniques and processes, and postoperative management of DAA-HJA in elderly patients with FNF, aiming to promote standardized, systematic and patient-specific diagnosis and treatment to improve the functional prognosis of the patients.

ObjectiveThe functional model of six major components of Astragali Radix-Angelicae Sinensis Radix combination against the proliferation of vascular smooth muscle cells （VSMCs） was constructed by uniform design， the relationship between the compatibility of these six main components and the inhibition of VSMCs proliferation was analyzed， and the effect of the compatibility of these main components of Astragali Radix-Angelicae Sinensis Radix on the proliferation of VSMCs as well as the feasibility of uniform design test in the study of multi-component compatibility of Chinese medicines were discussed. MethodCell proliferation and toxicity assay kit （CCK-8） method was used to determine the inhibitory effect of the six components of Astragali Radix-Angelicae Sinensis Radix on platelet derived growth factor-BB （PDGF-BB）-induced VSMCs proliferation in rats and the half inhibitory concentration （IC₅₀） of each component were obtained. Six chemical components of Astragali Radix-Angelicae Sinensis Radix （formononetin， astragaloside Ⅰ， astragaloside Ⅳ， calycosin， ferulic acid and calycosin-7-O-β-D-glucoside） were taken as the independent variables X₁， X₂， X₃， X₄， X₅， X₆， respectively， and the cell proliferation inhibition rate as the dependent variable Y. U24*（24⁹） uniform design table and mathematical models （including linear and quadratic polynomial） were selected， the stepwise regression method was used to screen the variables， and the better equations were obtained in theory. The actually better relationship equations were screened by setting the different dose compatibility of these six components for verification tests. According to the purpose of the experiment， the selected regression equation was processed by data centralization， so as to compare the regression coefficients of the data centralization equation and analyze the correlation between components and efficacy. ResultThe six components of Astragali Radix-Angelicae Sinensis Radix could inhibit abnormal proliferation of VSMCs in a dose-dependent manner. IC₅₀ values of formononetin， astragaloside Ⅰ， astragaloside Ⅳ， calycosin， ferulic acid and calycosin-7-O-β-D-glucoside were 123.453， 113.184， 81.655， 141.159， 101.187， 151.016 mg·L^-1， respectively. Two superior models were selected by experimental verification， including equation 1 of Y₁=73.137 897-0.207 888X₁+0.000 508X₂²+0.000 347X₁X₆ and equation 2 of Y₂=70.038 433-0.236 665X₁+0.000 577X₂²+0.000 260X₁X₄+0.000 415X₁X₆+0.000 370X₃X₅. After data centralization， equation 2 was adjusted to Y=-1.480 260-0.146 281X₁+0.000 673X₂²+0.000 314X₁X₄+0.000 456X₁X₆+0.000 737X₃X₅， the regression coefficients showed that the astragaloside Ⅰ had a positive effect on the inhibition rate of cell proliferation， formononetin-calycosin， formononetin-calycosin-7-O-β-D-glucoside and astragaloside Ⅳ-ferulic acid had an interaction effect on the inhibition rate of cell proliferation， and the synergistic effect of astragaloside Ⅳ and ferulic acid was higher than other interaction items. ConclusionThe combination of six main components of Astragali Radix-Angelicae Sinensis Radix can inhibit the abnormal proliferation of VSMCs， and it is demonstrated that the uniform test design can be used to predict the correlation between the chemical composition of Chinese medicines with their pharmacological effects， which can provide an experimental basis for the rational use of uniform design and regression analysis to construct mathematical models to study the compatibility relationship of Chinese medicines.

Objective:To investigate the safety and short-term efficacy of laparoscopic pro-ximal gastrectomy (LPG) for proximal gastric cancer and adenocarcinoma of esophagogastric junction.Methods:The retrospective cohort study was conducted. The clinicopathological data of 385 patients with proximal gastric cancer and adenocarcinoma of esophagogastric junction who underwent LPG in the 15 medical centers, including the First Affiliated Hospital of Xiamen University et al, from January 2014 to March 2022 were collected. There were 304 males and 81 females, aged (63±9)years.
