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.

Jinqi Jiangtang Capsule (JQJTC) is clinically used for the prevention and treatment of type 2 diabetes, but the contents of its main chemical components are not yet clear. In this study, an ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) method was established for the determination of 15 components in JQJTC, including new chlorogenic acid, chlorogenic acid, cryptochlorogenic acid, formononetin, ononin, calycosin, calycosin-7-glucoside, astragaloside IV, berberine, epiberberine, berberrubine, coptisine, jatrorrhizine, palmatine and magnoflorine. The method was used to determine the contents of 15 components in the capsule and then to investigate the influence of excipients on the contents of the components in JQJTC. The separation was performed on a ACQUITY UPLC BEH C₁₈ column (100 mm × 2.1 mm, 1.7 μm) with a mobile phase consisting of 0.1% acetic acid and 5 mmol·L^-1 ammonium acetate (A) and acetonitrile (B) with gradient elution at a flow rate of 0.3 mL·min^-1 and a column temperature at 40 ℃. Electron spray ionization was used for mass spectrometry in positive ion mode. The established method meets the requirements of methodology of content determination in Chinese pharmacopoeia. The contents of 15 components in JQJTC varied from high to low. The top 5 contents were berberine, chlorogenic acid, magnoflorine, coptisine, and cryptochlorogenic acid, accounting for 87.31% of the total content. The contents of 10 components, including the alkaloids of coptidis rhizoma (berberine, epiberberine, berberrubine, coptisine, jatrorrhizine, palmatine and magnoflorine) and the organic acids of honeysuckle (new chlorogenic acid, chlorogenic acid, and cryptochlorogenic acid) in the whole formula extract without excipients was significantly lower than that in the capsule. These components accounted for 99.20% of the determined component contents. In this experiment, an accurate, sensitive and efficient UHPLC-MS/MS method for the determination of multi-components in JQJTC was established, which stably and reliably detected the contents of 15 components in the capsule and could provide the basis for more comprehensive quality analysis. It was also found that excipients had an increasing effect on the contents of detected alkaloid and organic acid components, which may be beneficial to the effectiveness of the capsules.

Objective To investigate the effect of Xiao Chaihu Decoction and Xiangsha Liujunzi Decoction on the changes of gastric mucosal pathological score and gastrointestinal hormones in patients with chronic atrophic gastritis(CAG)of liver stagnation and spleen deficiency type.Methods A total of 156 cases of CAG patients with liver stagnation and spleen deficiency syndrome were randomly divided into a control group and an observation group,78 cases in each group.The control group was treated with conventional western medicine,and the observation group was treated with Xiao Chaihu Decoction and Xiangsha Liujunzi Decoction on the basis of treatment for the control group.The course of treatment covered four weeks.The changes in the scores of traditional Chinese medicine(TCM)symptoms such as epigastric distention and pain,poor appetite,loose stools,limb weakness,belching and acid regurgitation,gastric mucosal pathological scores and serum levels of gastrointestinal hormones of motilin(MTL)and gastrin(GAS)in the two groups were observed before and after treatment.The negative conversion rate of Helicobacter pylori(Hp)in the two groups was compared,and the clinical efficacy and safety of the two groups were evaluated.Results(1)After four weeks of treatment,the total effective rate of the observation group was 93.59％(73/78),which was significantly higher than 82.05％(64/78)of the control group,and the difference between the two groups was statistically significant(P＜0.05).(2)After treatment,the scores of TCM symptoms such as epigastric distention and pain,poor appetite,loose stool,limb weakness,belching and acid regurgitation in the two groups were significantly decreased compared with those before treatment(P＜0.05),and the decrease in the observation group was significantly superior to that in the control group(P＜0.05).(3)After treatment,the pathological scores of gastric mucosa in the two groups were significantly decreased when compared with those before treatment(P＜0.05),and the decrease in the observation group was more significant than that in the control group(P＜0.01).(4)After four weeks of treatment,the negative conversion rate of Hp in the observation group was 91.03％(71/78),which was significantly higher than that in the control group(75.64％,59/78),and the difference between the two groups was statistically significant(P＜0.05).(5)After treatment,the level of serum GAS in the two groups was significantly decreased(P＜0.05)and the serum MTL level was significantly increased compared with that before treatment(P＜0.05);the decrease of serum GAS level and the increase of serum MTL level in the observation group were significantly superior to those in the control group(P＜0.05).(6)There were no obvious abnormalities in the routine test of blood,urine,stool,kidney function,and liver function,electrocardiograph and other safety indicators during the treatment of the two groups of patients,no adverse reactions such as dizziness,rash and chest distress occurred either,with high safety.Conclusion Xiao Chaihu Decoction combined with Xiangsha Liujunzi Decoction exerts a significant therapeutic effect on GAS of liver stagnation and spleen deficiency type,which can effectively relieve the clinical symptoms,improve the pathological changes of gastric mucosa and promote Hp negative conversion.The therapeutic mechanism may be related to the regulation of gastrointestinal hormone levels.

Objective To explore the influential factors and predictive value of early femoral head collapse progression following allogeneic fibula grafting(AFG)surgery.Methods Clinical and radiological data of 68 patients(75 hips)with osteonecrosis of the femoral head(ONFH)who underwent AFG between January 2008 and December 2022 at the Orthopedics and Traumatology Department,Affiliated Hospital of Nanjing University of Chinese Medicine were retrospectively analyzed.Seventy-five hips were divided into stable(n=40)and progressive(n=35)groups based on the presence or absence of postoperative collapse progression.Age,gender,etiology,location of the lesion,Association Research Circulation Osseous(ARCO)stage,Japanese Committee of Osteonecrosis Investigation(JIC)classification,China-Japan Friendship Hospital(CJFH)classification,and Hounsfield units(HU)value of anterolateral sclerosis rim(ⅠSHU)were collected.Univariate and multivariate logistic regression analyses were used to identify the factors influencing early collapse progression after AFG.Receiver operating characteristic(ROC)curve was used to analyze the predictive value of the identified factors influencing postoperative early collapse progression.Results Of the 75 hips,35(46.7%)had postoperative collapse progression.Univariate logistic regression analysis showed that age,ARCO stage,JIC classification,and ⅠSHU were in fluencing factors for early femoral head collapse progression after AFG(P<0.05).Multivariate logistic regression analysis showed that ARCO stage ⅢA and JIC classification C2 were independent risk factors for early femoral head collapse progression after AFG,while ⅠSHU was identified as an independent protective factor(P<0.05).The ROC curve analysis showed that the sensitivities of ARCO stage,JIC classification,ⅠSHU,and the combined predictive model were 0.850,0.725,0.800,and 0.775,the specificities were 0.486,0.657,0.743,and 0.914,and the area under the ROC curve(AUC)were 0.668,0.725,0.811,and 0.896,respectively.Conclusions ⅠSHU is associated with early collapse progression after AFG in patients with ONFH.ARCO stage ⅢA,JIC classification C2,and ⅠSHU are independent factors influencing postoperative early collapse progression and have a certain predictive value.

Objective To evaluate the predictors of biochemical recurrence after laparoscopic radical prostatectomy.Methods The study cohort consisted of 416 consecutive prostatecancer patients who underwent radical prostatectomy in Zhongshan Hospital,Fudan University between Jan 2016 and Jun 2018.No patient received adjuvant therapy until documented biochemical recurrence.Biochemical recurrence-free survival(BCRFS)was estimated using the Kaplan-Meier method.Univariable and multivariable Cox proportional hazards regression models were utilized to determine variables predictive of biochemical recurrence.Results The median follow-up period was 174 weeks(inter quartile range 133-209 weeks).The overall biochemical recurrence rate was 21.39%(88/416).The time to biochemical recurrence was(51.11±47.71)weeks.Until the end of follow-up,the biochemical recurrence rates were 10%(1/10),6.12%(3/49),16.41%(43/262)and 43.16%(41/95)for low-risk,medium-risk,high-risk and locally advanced prostate cancer,respectively.On multivariable analysis,tumor invasion of the seminal vesicles(HR:2.119,95%CI:1.154-3.891,P=0.016);Seminal vesicle invasion(HR:1.824,95%CI:1.034-3.220,P=0.038),Gleason score≥8(HR:2.746,95%CI:1.268-5.943,P=0.010),prostate-specific antigen(PSA)=10-20 ng/mL(HR:4.240,95%CI:2.550-7.050,P<0.001);PSA>20 ng/mL(HR:6.341,95%CI:3.296-12.202,P<0.001)were the main predictors of biochemical recurrence.Conclusion Laparoscopic radical prostatectomy provides effective control of biochemical recurrence during the mid-term follow-up period.Tumor invasion of the seminal vesicles,seminal vesicle invasion,GS≥8,PSA=10-20 ng/mL,PSA>20 ng/mL were important predictors of biochemical recurrence after radical prostatectomy.

Objective To investigate the clinical and genetic features of children with 3-methylcrotonyl-coenzyme A carboxylase deficiency(MCCD).Methods A retrospective analysis was conducted on the clinical manifestations and genetic testing results of six children with MCCD who attended Children's Hospital Affiliated to Zhengzhou University from January 2018 to October 2023.Results Among the six children with MCCD,there were 4 boys and 2 girls,with a mean age of 7 days at the time of attending the hospital and 45 days at the time of confirmed diagnosis.Of all children,one had abnormal urine odor and five had no clinical symptoms.All six children had increases in blood 3-hydroxyisovaleryl carnitine and urinary 3-hydroxyisovaleric acid and 3-methylcrotonoylglycine,and five of them had a reduction in free carnitine.A total of six mutations were identified in the MCCC1 gene,i.e.,c.1630del(p.R544Dfs*2),c.269A>G(p.D90G),c.1609T>A(p.F537I),c.639+2T>A,c.761+1G>T,and c.1331G>A(p.R444H),and three mutations were identified in the MCCC2 gene,i.e.,c.838G>T(p.D280Y),c.592C>T(p.Q198*,366),and c.1342G>A(p.G448A).Among these mutations,c.269A>G(p.D90G)and c.1609T>A(p.F537I)had not been previously reported in the literature.There was one case of maternal MCCD,and the child carried a heterozygous mutation from her mother.Five children with a reduction in free carnitine were given supplementation of L-carnitine,and free carnitine was restored to the normal level at the last follow-up visit.Conclusions This study identifies two new mutations,c.269A>G(p.D90G)and c.1609T>A(p.F537I),thereby expanding the mutation spectrum of the MCCC1 gene.A combination of blood amino acid and acylcarnitine profiles,urine organic acid analysis,and genetic testing can facilitate early diagnosis and treatment of MCCD,and provide essential data for genetic counseling.

Objective To explore the efficacy and influencing factors of polyethylene glycol interferon α-2b(Peg-IFNα-2b)combined nucleoside analogues(NAs)in the treatment of hepatitis B virus e-antigen(HBeAg)-negative chronic hepatitis B(CHB)patients who had received NAs treatment,and evaluate the correlation of mononucleotide polymorphisms of interleukin-28B and programmed death receptor-1(PD-1)with interferon treatment response.Methods HBeAg-negative CHB patients who visited Xiangya Hospital of Central South University from January 2020 to December 2022 were analyzed retrospectively.Patients with Peg-IFNα-2b and NAs treatment were as the study group,while those with NAs therapy alone as the control group.Clinical efficacy of two groups of patients at the 12nd,24th,and 48th weeks of treatment,as well as the persistent response and recurrence at the 72nd week were analyzed.PD-1 and IL-28B single nucleotide polymorphisms were adopted to evaluate the value of HBeAg-nega-tive CHB patients in response to interferon treatment.Results At the 48th week of treatment,the response rate of HBeAg-negative CHB patients in the study group was higher than that in the control group(52.05％[38/73]vs 1.64％[1/61],P＜0.05).Among HBeAg-negative CHB patients in the study group,response rates at 48th week of treatment in patients with baseline HBsAg＜100 IU/mL and HBsAg＜1 000 IU/mL were higher than those with HBsAg≥1 000 IU/mL,respectively(both P＜0.05).Univariate and multivariate analyses showed that in HBeAg-negative CHB patients in the study group,the baseline HBsAg levels(OR=1.004,95％CI:1.001-1.006)and HBsAg decline magnitude at the 24th week of treatment(OR=0.111,95％CI:0.034-0.362)were influencing factors for the response of interferon treatment combined with NAs(both P＜0.05).The results of single nucleo-tide polymorphism analysis showed that in HBeAg-negative CHB patients in the study group,the proportion of PD-1 rs10204525 C/T heterozygous mutation in the response population was higher(66.67％vs 16.67％,P＜0.05),while that of IL-28B mutation was not significantly different(P＞0.05).Conclusion Combined treatment with Peg-IFNa-2b can achieve higher HBsAg clearance rate and serological conversion rate in HBeAg-negative CHB patients who had received NAs treatment.HBsAg decline magnitude at the 24th week of treatment can better pre-dict the response at the 48th week of treatment.Patients with low baseline HBsAg level and those carrying PD-1 rs10204525C/T heterozygous mutation gene present better therapeutic effect after receiving Peg-IFNa-2b.

Objective To investigate the distribution and antimicrobial susceptibility of clinically isolated bacteria from intensive care units(ICUs)in hospitals of Hunan Province Antimicrobial Resistance Surveillance System from 2012 to 2021.Methods According to China Antimicrobial Resistance Surveillance System,data of clinically isolated bacterial strains and antimicrobial susceptibility testing results of bacteria from ICUs reported by all member units of Hunan Province Antimicrobial Resistance Surveillance System were analyzed with WHONET 2022 software.Results From 2012 to 2021,the total number of bacteria isolated from ICUs of member units of the Hunan Province Antimi-crobial Resistance Surveillance System was 5 777-22 369,with Gram-negative bacteria accounting for 76.1％-78.0％annually.Staphylococcus aureus ranked first among isolated Gram-positive bacteria each year.The top 5 bacteria among Gram-negative bacteria were Acinetobacter baumannii,Klebsiella pneumoniae,Escherichia coli,Pseudo-monas aeruginosa,and Stenotrophomonas maltophilia.Detection rate of methicillin-resistant Staphylococcus aureus showed a downward trend year by year.No Staphylococcus spp.were found to be resistant to vancomycin,teico-planin and linezolid.Detection rates of vancomycin-resistant Enterococcus faecalis and vancomycin-resistant Entero-coccus faecium were 0.6-1.1％and 0.6％-2.2％,respectively.Resistance rates of Escherichia coli and Kleb-siella pneumoniae to imipenem were 3.1％-5.7％and 7.7％-20.9％,respectively.Resistance rates of Pseudo-monasaeruginosa and Acinetobacter baumannii to imipenem were 24.6％-40.1％and 76.1％-80.9％,respective-ly.Detection rates of carbapenem-resistant Pseudomonas aeruginosa declined year by year.Acinetobacter baumannii maintained high susceptibility to polymyxin B,with resistance rate＜10％.Conclusion Antimicrobial resistance of bacteria from ICUs is serious.Carbapenem-resistant Enterobacteriales has an upward trend after 2019.It is nece-ssary to strengthen the surveillance of bacterial resistance and carry out multidisciplinary collaboration.

Objective To investigate the effect of Ilizarov technique combined with rotational center dome-shaped osteoto-my in the treatment of juvenile distal femoral valgus deformity.Methods A retrospective study was conducted to analyze the clinical data of 11 patients with valgus deformity of the distal femur who had been admitted and followed up completely from January 2016 to October 2020.There were 7 males and 4 females.The 6 patients were on the right side and 5 patients were on the left side.The age ranged from 10 to 14 years old.The center of roration of angulation(CORA)was identified at the distal femur deformity,and dome-shaped osteotomy was performed with the CORA as the midpoint.The annular external fixator was installed according to the needle threading principle of Ilizarov external fixation,and the distal femur was cut off.The valgus deformity under visual inspection of the distal femur was corrected immediately,and the external fixator was fixed and main-tained.The residual deformity and shortening were corrected according to the force line and length of the lower limbs suggested by the weight-bearing full-length anteroposterior and lateral X-rays of both lower limbs.Results All 11 patients were followed up for 13 to 25 months.The time of wearing external fixator was 12 to 17 weeks.In the last follow-up,both lower limbs were measured by the weight-bearing full-length anteroposterior and lateral X-rays,and the length of both lower limbs of 11 patients were equal,and the deformities were corrected.The score of hospital for special surgery(HSS)was used to evaluate the knee function,all of which were excellent.Conclusion The Ilizarov technique was applied in the treatment of distal femoral valgus deformity in adolescents using a rotating central dome-shaped osteotomy.Visual femoral valgus deformity was corrected imme-diately during the operation.After the operation,residual deformities and shortening were dynamically adjusted and corrected according to the force line and shortening degree of lower extremities indicated by the weight-bearing anteroposterior and lateral radiographs of both lower limbs,with minimal damage and fast recovery.

Objective To investigate the therapeutic effects of proximal femoral nail antirotation(PFNA)assisted by robot navigation and PFNA guided by C-arm X-ray machine for the treatment of intertrochanteric fracture of femur(IFOF).Methods The 100 patients with unilateral IFOF in our hospital were selected as the study subjects.They were divided into the control group(50 cases)and the robot-assisted group(50 cases)according to random number table method.The control group was treated with PFNA internal fixation under C-arm X-ray machine fluoroscopy,and the robot-assisted group was treated with PFNA internal fixation assisted by robot navigation.Surgical indicators,fracture reduction and fracture healing,stress response indexes,hip joint function,quality of life score and incidence of surgery related complications were compared between the two groups.Results The operation time,total fluoroscopy time,nail placement time and fracture healing time of the robot-assisted group were shorter than those of the control group(P＜0.05);and the intraoperative blood loss,guide needle adjustment frequency,and fluoroscopy frequency of the robot-assisted group were less than those of the control group(P＜0.05).The fracture reduction and fracture healing in the robot-assisted group were better than those in the control group(P＜0.05).Two days after operation,the levels of serum norepinephrine(NE),angiotensin Ⅱ(Ang Ⅱ)and superoxide dismutase(SOD)in the two groups were higher than those before operation(P＜0.05),and the levels of serum NE,Ang Ⅱ and SOD in the robot-assisted group were lower than those in the control group(P＜0.05).The Harris score and 36-item short-form(SF-36)score of patients 7 days and 3 months after surgery in the two groups were higher than those before surgery(P＜0.05),and the above scores 3 months after surgery were higher than those 7 days after surgery(P＜0.05).Harris score and SF-36 score 7 days and 3 months after operation in the robot-assisted group were higher than those in the control group(P＜0.05).The incidence of complications in the robot-assisted group was lower than that in the control group(P＜0.05).Conclusion Compared with the C-arm X-ray machine fluoroscopy,the treatment of IFOF with PFNA assisted by robot navigation can further shorten the operation time,reduce the surgical trauma and the incidence of complications,achieve better effect of fracture reduction and healing,reduce stress response of the body,and improve hip joint function and quality of life for patients.
