This paper systematically reviews the current status of integrated traditional Chinese and western medicine in the treatment of Helicobacter pylori （Hp） infection， as well as recent progress in clinical and basic research both in China and internationally. It summarizes the advantages of traditional Chinese medicine （TCM） in Hp infection management， including improving Hp eradication rates， enhancing antibiotic sensitivity， reducing antimicrobial resistance， decreasing drug-related adverse effects， and ameliorating gastric mucosal lesions. These advantages are particularly evident in patients who are intolerant to bismuth-containing regimens， those with refractory Hp infection， and individuals with precancerous gastric lesions. An integrated， whole-process management approach and individualized， staged comprehensive treatment strategies combining TCM and western medicine are proposed for Hp infection. Future prevention and control of Hp infection should adopt an integrative Chinese-western medical strategy， emphasizing prevention， strengthening primary care， implementing proactive long-term monitoring， optimizing screening strategies， and advancing the development of novel technologies and mechanistic studies of Chinese herbal interventions. These efforts aim to provide a theoretical basis and practical pathways for the establishment and improvement of Hp infection prevention and control systems.

OBJECTIVES: This study aimed to evaluate the therapeutic effect of 1% povidone-iodine mouthwash combined with scaling and root planing in patients with stage Ⅰ/Ⅱ class A/B periodontitis, and to provide a basis for the clinical application of povidone-iodine mouthwash. METHODS: Seventy-five subjects were included in this trial and randomly divided into three groups. After full-mouth ultrasonic supragingival cleansing, scaling and root planing, the placebo group was treated with sodium chloride injection (NaCl group), the control group was treated with compound chlorhexidine mouthwash (CHX group), and the experimental group was treated with 1% povidone-iodine mouthwash (PVP-I group), and rinsed their mouths for 1 week, respectively. Subjects were tested at 1, 4, and 12 weeks after dosing for clinical indicators, microbial composition of supragingival plaque, gingival crevicular fluid inflammatory marker levels, and patient-reported outcomes. RESULTS: Sixty-three subjects completed the follow-up. After treatment, the clinical indicators, microbial indicators, and inflammatory indicators were all significantly improved (P<0.05). Comparisons among the groups showed that one week after treatment, the bleeding index and plaque index of the CHX group and the PVP-I group were lower than those of the NaCl group, and the plaque index of the CHX group was lower than that of the PVP-I group (P<0.05). There were no statistically significant differences in the other clinical indicators among the groups (P>0.05). Twelve weeks after treatment, the Shannon index of the CHX group was lower than that of the NaCl group (P<0.05), and there were no statistically significant differences in the other microbial indicators among the groups (P>0.05). Twelve weeks after treatment, the interleukin-10 concentration of the CHX group was higher than that of the NaCl group (P<0.05), and there were no statistically significant differences in the other inflammatory indicators among the groups (P>0.05). The PVP-I group had the highest scores in terms of taste and oral odor. There was no obvious staining on the tooth surfaces and mucosa in all three groups. CONCLUSIONS 1% PVP-I mouthwash combined with scaling and root planing can effectively reduce gingival inflammation and dental plaque, improve clinical symptoms in the short term. While its efficacy is not significantly inferior to that of chlorhexidine, PVP-I mouthwash is more acceptable to patients than chlorhexidine.

AIM:To investigate the impact of honokiol(HKL),an activator of silent information regulator 3(SIRT3),on postoperative cognitive dysfunction(POCD)in mice,and to explore the potential mechanisms.METHODS:Ten-month-old male C57/BL6 mice were randomly divided into control(Con)group,surgical(Sur)group and Sur+HKL group(n=10).The mice in Sur+HKL group were intraperitoneally injected with HKL for 7 d before modeling.The mice in Sur and Sur+HKL groups underwent tibial fracture open reduction and internal fixation to establish the POCD model.The assessment of cognitive function was conducted using the open-field test(OFT),novel object recognition test(NORT),Morris water maze test(MWMT),and Y-maze test(YMT).Nissl staining was employed to assess the morphology,struc-ture and vitality of hippocampal and cortical neurons in mice.The protein expression of glutathione peroxidase 4(GPX4),solute carrier family 7 member 11(SLC7A11),acyl coenzyme A synthetase long-chain family member 4(ACSL4),SIRT3 and nuclear factor E2-related factor 2(NRF2)in the mouse hippocampus was detected by Western blot,while im-munofluorescence staining was utilized to determine GPX4 level in mouse neurons.RESULTS:No statistically signifi-cant differences were observed among the groups in terms of total distance moved and central zone exploration during the OFT(P>0.05).However,the results from the NORT and YMT indicated that the mice in Sur group exhibited significant-ly lower recognition indexes,reduced alternation rates(P<0.01),and decreased percentages of entries and crossing time into the new arm after side arm blockade(P<0.01),when compared with Con group.Furthermore,the mice in Sur group demonstrated a slower decrease in latency during the learning period of MWMT,while significantly lower latency,fewer crossing number and lower percentage of time in the target quadrant were observed during the testing period of MWMT(P<0.01).The above indicators were obviously enhanced in Sur+HKL group compared with Sur group(P<0.01).The results of Nissl staining indicated lighter neuronal staining in the hippocampal CA1 region and medial prefrontal cortex in Sur group,accompanied by a significant reduction in the number of Nissl-stained positive neurons(P<0.01).Notably,HKL pretreatment demonstrated a significant improvement in neuronal vitality.Analysis of Western blot revealed that compared with Con group,the expression of SIRT3,GPX4,SLC7A11 and NRF2 in Sur group was significantly reduced,while the expression of ACSL4 was significantly increased(P<0.05).However,these alterations were reversed after treatment with HKL(P<0.05).Immunofluorescence staining of hippocampal neurons corroborated the findings from Western blot analy-sis,demonstrating a notable decrease in GPX4 expression in hippocampal neurons of Sur group,which was significantly restored after HKL pretreatment(P<0.01).CONCLUSION:Treatment with HKL attenuates POCD in mice,potentially through its inhibitory effect on hippocampal neuronal ferroptosis.

Objective To observe the effects of probiotics and lactulose synergistic action on gastroin-testinal motility,mucosal function and disease progression in elderly patients with type 2 diabetes mellitus(T2DM)nephropathy constipation.Methods A total of 108 elderly patients with T2DM nephropathy consti-pation admitted and treated in this hospital from May 2021 to March 2023 were selected as the study subjects and divided into the observation group,control group 1 and control group 2 by the random number table meth-od,36 cases in each group.The control group 1 was treated with bifidobacterium tetrad tablet,the control group 2 adopted the lactulose treatment,and the observation group was treated with bifidobacterium tetrad tablet combined with lactulose.The clinical efficacy,constipation symptoms before treatment and in 1,4 weeks after treatment,gastrointestinal motility,serum cerebrointestinal peptide[substance P(SP),nitric oxide(NO),vasoactive intestinal peptide(VIP)],intestinal mucosal barrier function[D-lactic acid(DLC),diamine oxidase(DAO),lipopolysaccharide(LPS)],renal function[creatinine(Cr),urea nitrogen(BUN),estimated glomerular filtration rate(eGFR)]and Toll-like receptor 4(TLR4)/nuclear factor κB(NF-κB)mRNA ex-pression were compared between the groups.Results After 1-,4-week treatment,the total effective rate,bari-um discharge rate at different time points in the observation group were higher than those in the control group 1 and control group 2,and the scores of rectal,abdominal and fecal traits in the observation group were lower than those in the control group 1 and control group 2(P＜0.05),but there was no statistically significant difference between the control group 1 and control group 2(P＞0.05).The serum NO and VIP levels in the observation group were lower than those in the control group 1 and control group 2(P＜0.05),the SP level was higher than that in the control group 1 and control group 2(P＜0.05).After 4-week treatment,the levels of serum DLC,DAO and LPS in the observation group were lower than those in the control group 1 and con-trol group 2(P＜0.05);the Cr and BUN levels,TLR mRNA expression and NF-κB mRNA expression in the observation group and control group 1 were decreased compared with before treatment(P＜0.05),the eGFR level was increased compared with before treatment(P＜0.05),but the above indexes had no statistically sig-nificant difference between these two groups(P＞0.05).Conclusion Probiotics and lactulose in the treat-ment of elderly patients with T2DM nephropathy constipation could play a synergistic role,alleviate the con-stipation symptom,promote the gastrointestinal motility and restore the intestinal mucosal barrier function,which may be reach the anti-inflammation and anti-apoptosis goal by inhibiting TLR4/NF-κB,so as to inhibit the further development of diabetic nephropathy.

ObjectiveTo investigate the immunological characteristics of the patients with aplastic anemia （AA） and elevated hemogram parameters treated with Yiqi Yangxue prescription combined with Western medicine and the predictive effects of immunological indexes on elevated hemogram parameters， thus providing a reference for the prediction of the treatment efficacy and the adjustment of the treatment regimen. MethodA retrospective study was conducted， involving 77 AA patients treated with Yiqi Yangxue prescription combined with Western medicine for 6 months in 19 medical institutions including Xiyuan Hospital， China Academy of Chinese Medical Sciences from September 2018 to March 2021. The patients were assigned into two groups according to the elevations in hemogram parameters ［including hemoglobin （HGB）， white blood cell count （WBC）， platelet （PLT）， and absolute neutrophil count （ANC）］ after 6 months of treatment. One group had the elevation <50%， and the other group had the elevation ≥50% compared with the baseline. The clinical and immunological characteristics were compared between the two groups. Result① Compared with the group with HGB elevation<50%， the group with HGB elevation≥50% showed elevated level of CD3⁺ human leukocyte antigen-DR （HLA-DR）⁺ and increased proportion of patients with T-helper cell type 2 （Th2）<5%， CD8⁺≥50%， and CD3⁺HLA-DR⁺≥9% before treatment （P<0.05， P<0.01）. The multivariate Logistic regression analysis showed that CD8⁺≥50% before treatment was the independent influencing factor for HGB elevation ≥50% ［odds ratio （OR）=12.000， 95% confidence interval （CI） 2.218， 64.928， P<0.01］. ② Compared with the group with WBC elevation<50%， the group with WBC elevation≥50% showed increased proportion of patients with CD3⁺HLA-DR⁺<6% and T-box transcription factor （T-bet）≥200% before treatment （P<0.05）. The multivariate Logistic regression analysis showed that CD3⁺HLA-DR⁺<6% （OR=2.998， 95%CI 1.036， 8.680， P<0.05） and T-bet≥200% （OR=3.634， 95%CI 1.076， 12.273， P<0.05） before treatment were independent influencing factors for WBC elevation≥50%. ③ Compared with the group with PLT elevation<50%， the group with PLT elevation≥50% presented lowered Th1 and CD3⁺HLA-DR⁺ levels and increased proportion of patients with Th1<12%， CD4⁺≥6%， and CD3⁺HLA-DR⁺<5% before treatment （P<0.05， P<0.01）. The multivariate Logistic regression analysis showed that CD3⁺HLA-DR⁺<5% before treatment was the independent influencing factor for PLT elevation≥50% （OR=16.190， 95%CI of 3.430 to 76.434， P<0.01）. ④ Compared with the group with ANC elevation<50%， the group with ANC elevation≥50% showed no significant changes in the hemogram parameters before treatment. ConclusionAs for the AA patients with rapid elevation in HGB， Yiqi Yangxue prescription combined with Western medicine demonstrate significant effects in the patients with Th2<5% and CD3⁺HLA-DR⁺≥9%， especially those with CD8⁺≥50%. As for the AA patients with rapid elevation in WBC， the therapy was particularly effective in the patients with CD3⁺HLA-DR⁺<6% and T-bet≥200%. As for the AA patients with rapid growth in PLT， the therapy was particularly effective in the patients with Th1<12% and CD4⁺≥6%， especially those with CD3⁺HLA-DR⁺<5%.

Objective This study aimed to investigate the temporal and spatial changes in the expression of perios-tin during periodontal inflammation in mice.Methods A periodontitis model was constructed using silk thread ligation.Mice were randomly divided into five groups in-cluding control group,4-day ligation group,7-day liga-tion group,14-day ligation group,and self-healing group(thread removal for 14 days after 14-day ligation).Mi-cro-CT and histological staining were performed to char-acterize the dynamic changes in the mouse periodontal tissue in each group.RNAscope and immunohistochemical staining were used to analyze the pattern of changes in peri-ostin at various stages of periodontitis.The cell experiment was divided into three groups:control group,lipopolysac-charide(LPS)stimulation group(treated with LPS for 12 h),and LPS stimulation removal group(treated with LPS for 3 h followed by incubation with medium for 9 h).Quantitative real-time polymerase chain reaction(qRT-PCR)was used to detect the expression of periostin,transforming growth factor-β1(TGF-β1),and matrix metalloproteinase 2(MMP2).Results Significant alveolar bone resorption was observed 7 days after ligation.With increasing duration of ligation,the damage to the mouse periodontal tissue was aggravated,which manifested as increased osteoclasts,widen-ing of the periodontal membrane space,and decreased alveolar bone height.Some degree of periodontal tissue repair was observed in the self-healing group.Periostin expression decreased at 4 and 7 days compared with the control group and increased at 14 days compared with 4 and 7 days.A significant recovery was found in the self-healing group.The qRT-PCR results showed that the expression of periostin and TGF-β1 in the LPS stimulation group decreased compared with that in the control group but significantly recovered in the LPS removal group.Conclusion Periostin expression in the PDL of mice showed a downward and upward trend with inflammation progression.The significant recovery of periostin expression after removing inflammatory stimuli may be related to TGF-β1,which is crucial to maintain the in-tegrity of the PDL.

Objective:To discuss the feasibility and safety of modified side overlap with fundoplication by Yamashita (mSOFY) in laparoscopic proximal gastrectomy.Methods:Using the method of descriptive case series study, the clinical data of 9 patients with upper gastric cancer who successfully performed mSOFY anastomosis from March 2022 to October 2022 in the Affiliated Huaian No.1 People's Hospital of Nanjing Medical University were retrospectively analyzed.The reconstruction steps of mSOFY anastomosis are as follows: (1) Make a small incision on the right side of the esophageal stump and in front of the anterior wall of the gastric stump; (2) The 45mm linear cutting stapler is placed into the preset anastomosis of the esophagus and the remnant stomach, and the esophagus is rotated 90° counterclockwise along the axis, so that the right wall of the esophagus is anastomosed with the remnant stomach, and the stomach wall is sutured to the left side of the esophagus; (3) The common opening of esophagus and remnant stomach was sutured with inverted suture; (4)Suture the left and lower sides of the esophagus with the remnant stomach to make the esophagus flat against the stomach wall; (5) Open the sutured common opening: due to the pressure of the false dome, the posterior wall of the lower esophageal segment was compressed into a valve-like structure. We mainly observing the postoperative reflux and nutritional improvement of the patients, and recording the intraoperative situation and postoperative complications.Results:Nine patients with upper gastric cancer who completed laparoscopic proximal gastrectomy (mSOFY anastomosis) did not have conversion to laparotomy or intraoperative / postoperative complications. The operation time was (169.4±10.4) minutes, the anastomotic reconstruction time was (51.7±7.1) minutes, the intraoperative bleeding volume was (98.9±43.4) ml, and the number of lymph nodes dissected was (27.2±6.7). The patient recovered well after operation, without any complaints related to reflux esophagitis. Postoperative gastrointestinal radiography showed that the anastomosis was smooth, without stenosis and leakage. The serum albumin [(41.6±3.4) L vs. (39.9±2.6) L], prealbumin [(211.3±38.6) mg/L vs. (205.3±36.0) mg/L], and hemoglobin levels [(126.7±13.2) g/L vs. (121.0±9.7) g/L] of patients before and one month after surgery have no statistically significant differences (all P>0.05). Conclusion:mSOFY anastomosis can be used as one of the safe and feasible reconstruction methods in laparoscopic proximal gastrectomy.

At present, the incidence of Parkinson's disease (PD) is gradually increasing. This seriously affects the quality of life of patients, and the burden of diagnosis and treatment is increasing. However, the disease is difficult to intervene in early stage as early monitoring means are limited. Aiming to find an effective biomarker of PD, this work extracted correlation between each pair of electroencephalogram (EEG) channels for each frequency band using weighted symbolic mutual information and k-means clustering. The results showed that State1 of Beta frequency band ( P = 0.034) and State5 of Gamma frequency band ( P = 0.010) could be used to differentiate health controls and off-medication Parkinson's disease patients. These findings indicated that there were significant differences in the resting channel-wise correlation states between PD patients and healthy subjects. However, no significant differences were found between PD-on and PD-off patients, and between PD-on patients and healthy controls. This may provide a clinical diagnosis reference for Parkinson's disease.
