Objective To observe the efficacy and safety of Morinda officinalis oligosaccharides in the continuation treatment of mild and moderate depression.Methods An open,single-arm,multi-center design was adopted in our study.Adult patients with mild and moderate depression who had received acute treatment of Morinda officinalis oligosaccharides were enrolled and continue to receive Morinda officinalis oligosaccharides capsules for 24 weeks,the dose remained unchanged during continuation treatment.The remission rate,recurrence rate,recurrence time,and the change from baseline to endpoint of Hamilton Depression Scale(HAMD),Hamilton Anxiety Scale(HAMA),Clinical Global Impression-Severity(CGI-S)and Arizona Sexual Experience Scale(ASEX)were evaluated.The incidence of treatment-related adverse events was reported.Results The scores of HAMD-17 at baseline and after treatment were 6.60±1.87 and 5.85±4.18,scores of HAMA were 6.36±3.02 and 4.93±3.09,scores of CGI-S were 1.49±0.56 and 1.29±0.81,scores of ASEX were 15.92±4.72 and 15.57±5.26,with significant difference(P＜0.05).After continuation treatment,the remission rate was 54.59％(202 cases/370 cases),and the recurrence rate was 6.49％(24 cases/370 cases),the recurrence time was(64.67±42.47)days.The incidence of treatment-related adverse events was 15.35％(64 cases/417 cases).Conclusion Morinda officinalis oligosaccharides capsules can be effectively used for the continuation treatment of mild and moderate depression,and are well tolerated and safe.

Objective To explore the efficacy of retropubic midurethral synthetic sling(RMUS)in relieving urgency and urge urinary incontinence(UUI)symptoms in patients with mixed urinary incontinence(MUI).Methods Clinical data of 44 female MUI patients treated with RMUS during Jan.2018 and Dec.2020 in Shanghai Renji Hospital were retrospectively analyzed.All patients had positive results in stress test and Marshall-Marchetti test before operation,and 27 of them completed ICIQ-FLUTS-LF questionnaire.Urodynamic(UDS)tests suggested that 9 patients(20.5％)presented detrusor overactivity(DO).During RMUS procedure,the tension of the sling was adjusted based on the anatomical landmarks.The postoperative efficacy and improvement of urinary incontinence were analyzed.Results The patients aged(58.59±9.08)years,with a body mass index of 24.71±2.77.Among the 40 patients who completed telephone interview 2 years after surgery,the subjective cure rate was 85.0％(34/40).Among the 27 patients with records of questionnaires before and after surgery,there were significant differences in the incidence of urine leakage[100％(27/27)vs.18.5％(5/27)],stress urinary incontinence(SUI)[100％(27/27)vs.18.5％(5/27)]and UUI[70.4％(19/27)vs.29.6％(8/27)](P＜0.05).However,no statistical differences were found regarding nocturia voiding episode(≥1 times),urgency,dysuria,hesitancy,strain to void,intermittent stream and enuresis(P＞0.05).Based on preoperative UDS test,there were significant differences regarding the subjective cure rate in patients with or without preoperative DO[55.6％(5/9)vs.93.5％(29/31)],incidence of SUI[66.7％(4/6)vs.4.8％(1/21)],and UUI[66.7％(4/6)vs.19.0％(4/21)](P＜0.05),while there was no statistical difference regarding urgency[66.7％(4/6)vs.33.3％(7/21)](P＞0.05).Conclusion RMUS is effective in treating MUI patients with positive stress test and Marshall-Marchetti test results,which can relieve SUI and UUI symptoms,but has no effects on urgency symptoms.DO on preoperative urodynamics results in poorer subjective outcomes.

Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.

Objective To investigate the clinical characteristics and prognosis of pneumococcal meningitis(PM),and drug sensitivity of Streptococcus pneumoniae(SP)isolates in Chinese children.Methods A retrospective analysis was conducted on clinical information,laboratory data,and microbiological data of 160 hospitalized children under 15 years old with PM from January 2019 to December 2020 in 33 tertiary hospitals across the country.Results Among the 160 children with PM,there were 103 males and 57 females.The age ranged from 15 days to 15 years,with 109 cases(68.1% )aged 3 months to under 3 years.SP strains were isolated from 95 cases(59.4% )in cerebrospinal fluid cultures and from 57 cases(35.6% )in blood cultures.The positive rates of SP detection by cerebrospinal fluid metagenomic next-generation sequencing and cerebrospinal fluid SP antigen testing were 40% (35/87)and 27% (21/78),respectively.Fifty-five cases(34.4% )had one or more risk factors for purulent meningitis,113 cases(70.6% )had one or more extra-cranial infectious foci,and 18 cases(11.3% )had underlying diseases.The most common clinical symptoms were fever(147 cases,91.9% ),followed by lethargy(98 cases,61.3% )and vomiting(61 cases,38.1% ).Sixty-nine cases(43.1% )experienced intracranial complications during hospitalization,with subdural effusion and/or empyema being the most common complication[43 cases(26.9% )],followed by hydrocephalus in 24 cases(15.0% ),brain abscess in 23 cases(14.4% ),and cerebral hemorrhage in 8 cases(5.0% ).Subdural effusion and/or empyema and hydrocephalus mainly occurred in children under 1 year old,with rates of 91% (39/43)and 83% (20/24),respectively.SP strains exhibited complete sensitivity to vancomycin(100% ,75/75),linezolid(100% ,56/56),and meropenem(100% ,6/6).High sensitivity rates were also observed for levofloxacin(81% ,22/27),moxifloxacin(82% ,14/17),rifampicin(96% ,25/26),and chloramphenicol(91% ,21/23).However,low sensitivity rates were found for penicillin(16% ,11/68)and clindamycin(6% ,1/17),and SP strains were completely resistant to erythromycin(100% ,31/31).The rates of discharge with cure and improvement were 22.5% (36/160)and 66.2% (106/160),respectively,while 18 cases(11.3% )had adverse outcomes.Conclusions Pediatric PM is more common in children aged 3 months to under 3 years.Intracranial complications are more frequently observed in children under 1 year old.Fever is the most common clinical manifestation of PM,and subdural effusion/emphysema and hydrocephalus are the most frequent complications.Non-culture detection methods for cerebrospinal fluid can improve pathogen detection rates.Adverse outcomes can be noted in more than 10% of PM cases.SP strains are high sensitivity to vancomycin,linezolid,meropenem,levofloxacin,moxifloxacin,rifampicin,and chloramphenicol.[Chinese Journal of Contemporary Pediatrics,2024,26(2):131-138]

For the past 30 years,percutaneous balloon mitral valve dilatation has been performed under the guidance of X-rays and bedside ultrasound.However,there are still some cases of mitral valve stenosis in the large atrium where balloon dilation failed.Intraperitoneal ultrasound-guided percutaneous balloon mitral valve plasty is accurate and feasible,which can reduce the occurrence of complications and improve the success rate of such elderly complex cases.Two patients with severe mitral stenosis underwent percutaneous balloon mitral valve plasty guided by intracardiac ultrasound.The operations were successful without any complications,which can provide reference for clinical treatment of mitral stenosis.

[Objective] To explore the application of pelvic floor ultrasonography in the treatment of mixed urinary incontinence (MUI) by transvaginal retropubic midurethral synthetic sling (RMUS), in order to understand the relationship between the morphological changes of pelvic floor structures and the efficacy of RMUS. [Methods] Clinical data of 44 female MUI patients undergoing RMUS during Jan.2018 and Dec.2020 were retrospectively analyzed.Urodynamics detected detrusor overactivity (DO) in 9 cases (20.5%). During RMUS procedure, the tension of the sling was adjusted based on the anatomical landmarks. The changes of ultrasonic parameters before and after operation, the relationship between the ultrasonic results, surgical efficacy and urodynamic results were analyzed. [Results] The patients averaged (58.59±9.08) years, with the body mass index being 24.71±2.77.The subjective cure rate was 91.3% (21/23) 3 months after surgery, and 85.0% (34/40) 2 years after surgery.Pelvic floor ultrasonography showed significant differences in posterior urethravesical angel at rest and during Valsalva, bladder neck descent distance and the rate of urethral funneling during Valsalva (P<0.05). According to the group analysis of the preoperative ultrasonic results, there was no statistical significance in the subjective cure rate between the funneling group and the non-funneling group during Valsalva, and the bladder neck non downward group/mild downward group/moderate downward group/severe downward group during Valsalva 3 months and 2 years after surgery (P>0.05). At 3-month follow-up, all pre-RMUS urethral funneling during Valsalva disappeared in patients without preoperative DO.Comparatively, 50.0% (3/6) urethral funneling still presented in DO patients, who had a lower cure rate (55.6%, 5/9) at the 2-year follow-up. [Conclusion] RMUS can reduce the posterior urethravesical angel at rest and during Valsalva, reduce bladder neck descent distance and the rate of urethral funneling during Valsalva in MUI patients, which can enhance urinary continence.There seems to be a correlation between DO and urethral funneling during Valsalva, while RMUS may potentially reverse the two markers.

Objective:We aimed to develop a novel visualized model based on nomogram to predict postoperative overall survival.Methods:This was a multicenter, retrospective, observational cohort study, including participants with histologically confirmed gastric and colorectal cancer who underwent radical surgery from 11 medical centers in China from August 1, 2015 to June 30, 2018. Baseline characteristics, histopathological data and nutritional status, as assessed using Nutrition Risk Screening 2002 (NRS 2002) score and the scored Patient-Generated Subjective Global Assessment, were collected. The least absolute shrinkage and selection operator regression and Cox regression were used to identify variables to be included in the predictive model. Internal and external validations were performed.Results:There were 681 and 127 patients in the training and validation cohorts, respectively. A total of 188 deaths were observed over a median follow-up period of 59 (range: 58 to 60) months. Two independent predictors of NRS 2002 and Tumor-Node-Metastasis (TNM) stage were identified and incorporated into the prediction nomogram model together with the factor of age. The model's concordance index for 1-, 3- and 5-year overall survival was 0.696, 0.724, and 0.738 in the training cohort and 0.801, 0.812, and 0.793 in the validation cohort, respectively.Conclusions:In this study, a new nomogram prediction model based on NRS 2002 score was developed and validated for predicting the overall postoperative survival of patients with gastric colorectal cancer. This model has good differentiation, calibration and clinical practicability in predicting the long-term survival rate of patients with gastrointestinal cancer after radical surgery.

Objective:To explore the effects of body mass index (BMI) on the incidence of nocturnal hypertension in patients with hypertension.Methods:Totally 341 hospitalized hypertensive patients treated at the Affiliated Hospital of Jining Medical University from February to May 2023 were selected by convenience sampling. Patients' general information, clinical data, and 24-hour ambulatory blood pressure results were collected. A binomial Logistic regression analysis was conducted to investigate the factors affecting the occurrence of nocturnal hypertension in these patients. The relationship between BMI and the incidence of nocturnal hypertension was examined using threshold effect tests and smooth curve fitting.Results:The binomial Logistic regression analysis indicated that blood phosphate level was a factor influencing the occurrence of nocturnal hypertension in hypertensive patients ( P<0.05). Smooth curve fitting and threshold effect test results showed that the relationship between BMI and the incidence of nocturnal hypertension was curve-correlated, with a turning point at 24.61 kg/m 2. To the left of the turning point, there was no correlation ( P=0.130) ; to the right, there was a correlation ( P=0.016) . Conclusions:When the BMI of hypertensive patients exceeds 24.61 kg/m 2, the likelihood of nocturnal hypertension increases with rising BMI, providing a precise intervention target for weight management-based patient care in hypertension.

Objective:To analyze the genetic evolution and molecular characteristics of H7N9 avian influenza virus (AIV) isolated in a live poultry market.Methods:Samples such as poultry feces, sewage, and hair removal machine and chopping board swabs were collected. Real-time fluorescent quantitative PCR was used to detect influenza A virus and H7N9 AIV in the samples. The whole genome of H7N9 AIV was amplified with influenza A virus universal primers and sequenced. BLAST and MEGA X were used for sequence alignment, phylogenetic analysis and molecular characterization.Results:Seven poultry-related environment samples were collected in the live poultry market in Xuchang city in February 2023, and four were positive for H7N9 AIV. The whole genome sequences of three H7N9 AIV isolates were successfully obtained, and the isolates shared high nucleotide identity in different genes (98.37%-100.00%). BLAST analysis showed they were highly identical to H7N9 strains isolated from domestic poultry in China from 2020 to 2021. Genetic evolution analysis showed that the three isolates clustered in the same branch and were closer to the recent environmental isolates than to the recent strains isolated from human or avian. Through comparison with the sequences of the representative strains in different periods, it was found that the isolated strains in this study showed high avian pathogenicity with four amino acids KRAA inserted at the cleavage site; the hemagglutinin receptor-binding site was QSG, which was an avian binding receptor; there was a G186I mutation in hemagglutinin. Mammalian-adaptive mutation E627K was not detected in polymerase basic protein 2. Mutations (R292K and I38T) associated with drug resistance to neuraminidase inhibitor (oseltamivir) and polymerase acidic protein inhibitor (baloshavir) were not detected, suggesting that these isolates remained susceptible to these drugs. A S31N mutation was found in M2 protein, indicating they were resistant to alkamines.Conclusions:The three H7N9 AIV strains isolated in the live poultry market have high avian pathogenicity, but there are no significant increase in mutations related to the binding ability to human receptors, mammalian pathogenicity, viral transmissibility, or drug resistance as compared with previous representative strains causing human or avian infection.

Objective:To analyze the reinfection rates in people previously infected with SARS-CoV-2 in Zhengzhou and Yuzhou cities (first infected with Delta/B.1.617.2 variant), and Anyang city (first infected with Omicron/BA.1.1 variant) in January 2022 and the population characteristics, and compare the differences in antibody levels among different populations.Methods:Serum samples were collected from 371 previously infected, 134 reinfected and 19 uninfected people for IgG antibody detection. Among them, serum samples from 45 previously infected, 44 reinfected and 19 uninfected people were tested with different novel coronavirus variants (early original strain, BA.5.2 variant, XBB.1.5 variant) for neutralizing antibody detection.Results:The rate of reinfection was 32.82% (85/259) in Zhengzhou and Yuzhou cities, and 19.92% (49/246) in Anyang city. The IgG antibody level in reinfected people was higher than that in previously infected and uninfected people ( P<0.05). The IgG antibody level in uninfected group was higher in people vaccinated within three months than in those vaccinated six months ago ( P<0.05). The IgG antibody level in the group receiving four doses of vaccine was higher than that in the group receiving three doses of vaccine ( P<0.05). The results of true virus neutralization antibody detection showed that in the Zhengzhou and Yuzhou cases, the level of neutralization antibody against the early original strain was higher than those against the BA.5.2 variant and the XBB.1.5 variant ( P<0.05), and the level of neutralizing antibody against BA.5.2 variant was higher than that against XBB.1.5 variant ( P<0.05). In Anyang city cases, the level of neutralizing antibody against the early original strain was higher than those against BA.5.2 variant and XBB.1.5 variant ( P<0.05); in the reinfected population, the level of neutralizing antibody against the early original strain was higher than that against the XBB.1.5 variant ( P<0.05). In addition, the levels of all neutralizing antibodies in both previously infected and reinfected people were higher than those in uninfected people ( P<0.05). The level of neutralizing antibody in the infected population in Zhengzhou and Yuzhou cities was higher than that in the infected population in Anyang city and in uninfected population ( P<0.05). The levels of antibodies against BA.5.2 and anti-XBB.1.5 variants in infected people in Zhengzhou and Yuzhou cities were higher than those in uninfected people ( P<0.05). The level of neutralizing antibody against BA.5.2 variants in the previously infected population in Anyang city was higher than that in the uninfected population ( P<0.05), and the level of neutralizing antibody against XBB.1.5 variants in the infected population in Anyang city was higher than that in the uninfected population ( P<0.05). Conclusions:After infection with SARS-CoV-2, the neutralizing antibodies produced in the human body have a certain cross-protection effect on other variants, but the antibody level will gradually decrease over time. Protection from a previous early SARS-CoV-2 variants infection against the current main circulating Omicron variants (such as XBB variants) is low, and the immunity conferred by pervious infection or booster vaccination may not be able to provide sufficient protection against new variants.
