The incidence of chronic venous disease(CVD)is significantly higher in the elderly population compared to non-elderly individuals,with more severe disease manifestations.Additionally,elderly CVD patients often have comorbid conditions such as cardiovascular diseases,making the evaluation process more complex and increasing treatment difficulty.Currently,there are no established recommendations in China for the diagnosis and treatment of CVD in individuals aged 60 and above.Against this backdrop,the Peripheral Vascular Disease Management Branch of the Chinese Geriatric Society has developed the Chinese Expert Consensus on the Diagnosis and Treatment of Chronic Venous Disease in the Elderly based on domestic and international guidelines,relevant evidence-based medical research,and the physiological and clinical characteristics of the elderly population in China.This consensus aims to provide an important reference for improving the diagnosis and treatment of CVD in elderly patients in China.

Objective:To investigate the feasibility of employing high-resolution colon manometry (HRCM) in conjunction with natural orifice specimen extraction surgery (NOSES) during laparoscopic Jinling surgery for the treatment of colonic slow transit constipation (STC).Methods:This study retrospectively analyzed data from nine patients with STC who underwent HRCM preoperative evaluation and subsequently received NOSES Jinling surgery at Tianjin Union Medical Center between October 2016 and March 2023. The general intraoperative conditions and postoperative evaluation indicators were recorded.Results:All 9 patients underwent HRCM examination before surgery. High amplitude propagation contraction (HAPC) was observed in the ascending colon segment of all patients. The occurrence frequency of HAPC was 4.22±1.86 (times/day). The operation time of 9 patients was 200.0 (167.5, 250.0) minutes, the intraoperative blood loss was 100 (50, 150) ml, the postoperative hospitalization time was 13.0 (12.5, 24.0) days, and the first postoperative exhaust time was 3.0 (2.0, 3.5) days, the first postoperative defecation time was 5.0 (4.5, 5.5) days, the first postoperative eating time was 5.0 (5.0, 5.5) days, and the first postoperative time out of bed was 5.0 (5.0, 8.0) days. Notably, none of the 9 patients experienced postoperative complications. The Wexner scores at 6 months [5 (4, 7)], and 12 months [4 (3, 5)] post-surgery were significantly lower than the preoperative score [20 (16, 21)] ( P<0.05). Additionally, the patient assessment of constipation quality of life (PAC-QOL) scores at 6 months [22 (20, 25)], and 12 months [18 (12, 45)] after surgery showed a significant decrease compared to preoperative scores [79 (72, 82)] ( P<0.05). Conclusions:The combination of HRCM preoperative assessment and NOSES Jinling surgery is both safe and feasible for the treatment of slow transit constipation, warranting further development and promotion.

Objective:To summarize clinical characteristics and prognosis of immune checkpoint inhibitor (ICI) -related Stevens-Johnson syndrome (SJS) /toxic epidermal necrolysis (TEN) .Methods:A retrospective analysis was conducted on patients diagnosed with ICI-related SJS/TEN in Zhongda Hospital, Southeast University from January 2018 to October 2023. Data on clinical manifestations, laboratory examinations, treatment and prognosis of the patients were analyzed.Results:A total of 9 patients were diagnosed with ICI-related SJS/TEN, including 8 males and 1 female, with the onset age ranging from 58 to 77 (67.56 ± 7.33) years. ICI were applied to all the 9 patients before onset of SJS/TEN. The latent period was 6 - 261 d, and the median duration was 76 d. All the patients presented with erythema as initial lesions, 3 cases with target lesions, 6 with blisters, and 5 cases with a positive Nikolsky's sign. Oral mucosal damage occurred in 7 cases, eye damage occurred in 6 cases, and urogenital damage occurred in 6 cases. All the 9 cases were treated with systematic glucocorticoids, 7 cases with intravenous immunoglobulin and 7 cases with antibiotics. Eight cases recovered and 1 case died. Among 6 patients followed for an average of 6.92 months, none achieved complete or partial remission, 3 died and 3 experienced disease progression.Conclusions:ICI-related SJS/TEN occurred with a relatively long latent period, and all the cases presented with erythema initially, with mucosal damage present in most of the cases. Management required discontinuation of ICI, and most patients recovered with corticosteroids and intravenous immunoglobulin, however, the prognosis for the primary malignancy remained poor.

Objective:To explore clinical characteristics of multiple sclerosis(MS)patients in Suzhou,and to analyze main factors affecting their prognosis.Methods:General data,clinical symptoms,cerebrospinal fluid and imaging examinations of 51 MS patients admitted to Department of Neurology of the Second Hospital of Soochow University from July 31,2009 to July 31,2021 were retrospectively analyzed,and main factors affecting their prognosis were discussed.Results:Average age of onset of 51 MS patients was(43.3±15.6)years old,female accounted for 56.9%,male/female=1/1.3.Adult onset MS(AOMS)accounted for 62.8%,male/female=1/1.7;late onset MS(LOMS)accounted for 37.2%,male/female=1/0.9.Relapsing remitting MS(RRMS)accounted for 76.5%,and chronic onset accounted for 60.8%.Average annual recurrence rate was 8.8%.The first symptoms were numbness and weakness of limbs.Dizziness and numbness were more common in patients without recurrence after diagnosis of MS,and limb weak-ness and numbness were more common in patients with recurrence.Among lesions of MRI,62.7%(32/51)of periventricular involve-ment,52.9%(27/51)of spinal cord involvement,51.0%(26/51)of infratentorial involvement.Proportion of subtentorial and spinal cord(cervical,thoracic)involved were significantly higher in patients with recurrent MS than without recurrence.Values of albumin,IgG,IgA and IgM in cerebrospinal fluid increased with increase of recurrence times.EDSS score of male was higher than female,and LOMS score was higher than AOMS.MS patients without relapse had a low EDSS score,and median EDSS score at current follow-up was 0(0,1.00)score.MS score with relapse was relatively high,and median EDSS score at current follow-up was 2.75(0.25,7.25)score.Conclusion:MS patients with chronic onset are more common,with a high proportion of LOMS,and proportion of males increases with increasing age of onset.High EDSS score at first onset,cervical,thoracic and subtentorial lesions,increased values of cerebrospinal fluid albumin,IgG,IgA,IgM,age at first onset(50+years old),male associate with poor MS prognosis.

Objective To explore the feasibility of treating recurrent mandibular neuralgia with radiofrequency thermocoagulation with double needle guide,and to study the clinical value of double needle puncture for foramen ovale.Methods In this study,40 patients with recurrent mandibular neuralgia admitted to our hospital from January 2018 to November 2023 were selected,and randomly divided into the observation group(20 cases using double-needle guide technology)and control group(20 cases using traditional single-needle guide technology).The two groups were compared before and after treatment.Results After the completion of radiofrequency thermo-coagulation therapy,the overall pain-free rate of all cases was 90％according to the adjusted grading criteria,and there was a differ-ence in the pain-free rate between the two groups(P＜0.05).There was no significant difference in the number of puncture adjustment and complications between the two groups(P＞0.05).The operation time of the observation group was longer than that of the control group(P＜0.05),and the number of postoperative acupuncture pain cases was statistically different from that of the control group(P＜0.05).After comparison of facial visual analogue scale(F-VAS),it was found that there were significant differences between the two groups(P＜0.05),and there were statistical differences between the observation group and the control group(P＜0.05).Conclusion Radiofrequency thermocoagulation with double-channel technique treating patients with recurrent mandibular neuralgia is,more thorough and has less complications.Although the operation time is increased,it can effectively eliminate the pain of patients.The tra-ditional bipolar radiofrequency thermocoagulation therapy technology is easily and accurately accomplished,which is worth popularizing.

Objective To investigate the differences in cortical activation and functional connectivity during speech under different cognitive loads in young individuals.Methods Twenty-one participants(mean age 21.9±1.33 years)were instructed to read short sentences embedded with color words under both congruent(where the color words matched the font color)and incongruent(where the color words did not match the font color)condi-tions.The color words required reading the font color instead of the word itself.Functional near-infrared spectros-copy(fNIRS)was utilized to analyze differences in cortical activation(changes in HbO concentration)and functional connectivity(Pearson correlation of HbO between brain regions)in the dorsolateral prefrontal cortex(DLPFC)and supplementary motor area(SMA)bilaterally.Results The fNIRS results revealed significant increase in HbO con-centration changes in the RDLPFC(t=3.4,P=0.003),LDLPFC(t=2.58,P=0.019),RSMA(t=3.59,P=0.002),and LSMA(t=4.06,P=0.001)under the incongruent condition compared to the congruent condition.Additionally,there was a significant enhancement in the correlation between RDLPFC and LDLPFC(t=2.44,P=0.025).However,the differences in correlation between left and right SMA,as well as between SMA and DLPFC,were not statistically significant(P＞0.05).Conclusion These findings suggest that during speech under incongru-ent conditions,increased cognitive load leads to elevated cortical activation in the DLPFC and SMA,along with in-creased functional connectivity between the left and right DLPFC.

OBJECTIVE To explore the potential mechanism of Yiqi Wenyang Recipe in the intervention of allergic rhinitis(AR)mice.METHODS C57/BL6 mice were randomly divided into blank,model,Yiqi Wenyang Recipe and Yiqi Wenyang Recipe+EX-527[Sirtuin 1(SIRT1)inhibitor]groups.The AR model of mice was established by ovalbumin based challenge sensitization method,each group received corresponding intervention measures.Assessment of behavioral changes in mice;nasal mucosal lesions were observed by HE and toluidine blue staining;the serum levels of interleukin-4(IL-4),interferon-γ(IFN-γ),and immunoglobulin E(IgE)were measured by ELISA;the expression levels of phospho-Janus kinase 2(p-JAK2),phospho-signal transducer and activator of transcription 6(p-STAT6),phospho-dynamin-related protein 1(p-Drp1),SIRT1,peroxisome proliferator-activated receptor gamma coactivator 1-alpha(PGC-1α)in nasal mucosa were determined by Western blot combined with immunofluorescence;reactive oxygen species(ROS)levels were detected by fluorescent probe method;the morphological changes of mitochondria in the microstructure of na-sal mucosa were observed by transmission electron microscopy.RESULTS Compared with the blank group,the frequency of scratch-ing and sneezing in the model group was significantly increased,and a large number of eosinophils and mast cells were found in the na-sal mucosa(P<0.05);compared with the model group,the nasal allergic symptoms and the level of nasal mucosal inflammatory reaction in the Yiqi Wenyang Recipe group were significantly improved(P<0.05);compared with the Yiqi Wenyang Recipe group,the scratch-ing and sneezing of mice in the Yiqi Wenyang Recipe+EX-527 group increased again,and the counts of eosinophils and mast cells in nasal mucosa increased significantly(P<0.05).Compared with the model group,the levels of serum IL-4 and IgE in the Yiqi Wenyang Recipe group decreased,while the level of serum IFN-γ increased(P<0.05);the serum IL-4 and IgE of mice in the Yiqi Wenyang Recipe+ex-527 group were significantly higher than those in the Yiqi Wenyang Recipe group(P<0.05).Western blot and immunofluo-rescence showed that Yiqi Wenyang Recipe could effectively inhibit the increase of p-JAK2,p-STAT6,p-Drp1(ser616)levels induced by ovalbumin sensitization,as well as the decrease of SIRT1 and PGC-1 α expression(P<0.01);however,the intervention of EX-527 significantly blunted the regulatory effect of Yiqi Wenyang Recipe on the above signaling molecules(P<0.05,P<0.01).The results of transmission electron microscopy and fluorescent probe showed that in the model group,a large number of spherical mitochondria were found in the mitochondria of nasal mucosa,and the level of ROS was significantly increased(P<0.01);;the intervention of Yiqi We-nyang recipe effectively restored the long tubular morphology of mitochondria and reduced ROS level(P<0.01);,while the intervention of EX-527 weakened the above improvement effect(P<0.01).CONCLUSION Yiqi Wenyang Recipe can regulate SIRT1 to activate PGC-1α,and then inhibit Drp1 mediated excessive mitochondrial fission to intervene AR;SIRT1 may be one of the important targets of Yiqi Wenyang Recipe in the intervention of AR.
