BACKGROUND:Exercise has a regulatory effect on intestinal flora dysbiosis,which can effectively protect the beneficial flora and improve the intestinal environment.However,the effect of treadmill exercise on the structure and diversity of intestinal microbial community in Parkinson's disease and the specific mechanism are not clear. OBJECTIVE:Using 16S rDNA technique to analyze the effect of treadmill exercise on the structure and diversity of the intestinal flora of rats with Parkinson's disease,and to investigate the mechanism of non-pharmacological treadmill exercise to improve Parkinson's disease. METHODS:Twelve of the 18 Sprague-Dawley rats were randomly selected to make animal models of Parkinson's disease using unilateral 2-point nigrostriatal injection of 6-hydroxydopamine.The remaining six rats were used as sham-operation group,which were injected with the same dose of saline containing 0.2%ascorbic acid using the same positioning and injection method.After successful modeling,12 rats with Parkinson's disease were randomly divided into model group and treadmill exercise group(n=6 per group).The treadmill exercise group was subjected to a middle and low intensity tread mill exercise,10 m/min,30 minutes per day,5 days per week for 4 weeks.Fresh feces were collected and stored in liquid nitrogen 24 hour after the last exercise session,and the changes in fecal flora were analyzed by 16S rDNA sequencing technique. RESULTS AND CONCLUSION:Treadmill exercise significantly improved behavior and nigrostriatal tyrosine hydroxylase-positive cell expression in rats with Parkinson's disease model and alleviated changes in the structure and diversity of the gut microbial community caused by Parkinson's disease,increased the number of operational taxonomic units and modulated Alpha and Beta diversity in rats.At the phylum and genus levels,the abundance ratio of Firmicutes/Bacteroidetes in the model group decreased compared with the sham-operated group,while beneficial bacteria such as Prevotella,Bacteroides,and Clostridium_XlV increased significantly after treadmill exercise.To conclude,treadmill exercise has a significant modulating effect on behavioral abnormalities,toxic damage to dopaminergic neurons and gut microbial imbalance caused by Parkinson's disease,alleviates the symptoms of flora-related diseases,and has a positive effect on the improvement of Parkinson's disease.

Objective To investigate the effects of the eucalyptol,limonene and pinene enteric soft capsules (mucoregulatory agents) in preventing from tympanum fluid in children.Methods A total of 341 children (497 ears) with acute otitis media were randomly divided into two groups:the experimental group and the control group.The experimental group was given symptomatic treatment and oral in-take of the eucalyptol,limonene and pinene enteric soft capsules,while the control group with acute otitis media received conventional symptomatic treatment.All the patients were followed-up 7 and 14 days after treatment.Clinical data were collected,including symptoms,and tympanogram changes.Results Seven days after the initial treatment,tympanum fluid occurred in 110 cases of 170 ears(65.09％,110/170) in the control group,and in 51 cases of 70 ears (29.65％,51/172) in the experimental group.The difference was statistically significant (P＜0.01).After 14 days,41 cases (66 ears)of tympanum fluid occurred in the control group (24.26％,41/169),32 cases(36 ears) of otitis media (18.60％,32/172) occurred in the experimental group.The difference was statistically significant (P＜0.01).In the control group,the tympanum fluid disappeared in 54 cases(60 ears) after regular treatment 72.0％,54/75),and reliefed in 15 cases(22 ears) with irregular treatment (42.86％,15/35).The difference was statistically significant (P＜0.01).Conclusion Eucalyptol,limonene and pinene enteric soft capsules can effectively reduce the incidence of tympanum fluid in children with acute otitis media.Mucoregulatory agents may promote the eduction of effusion.

Aim To observe the effect of total flavonoid from Mori folium(TFMF) on renal interstitial fibrosis in type 1 diabetic mice and its possible mechanism.Methods Diabetic mice were induced by intraperitoneal injection of streptozotocin(STZ) dissolved in 0.01 mol·L-1 citrate buffer(pH 4.5) at 150 mg·kg-1 body weight after 12 h of food deprivation.Forty model mice were divided randomly into four groups: model group, and low-(0.25 g·kg-1), moderate-(0.5 g·kg-1), high-dose groups(1 g·kg-1) fed with TFMF once daily.In addition, eight normal mice were used as normal group.After 12 weeks, the fasting blood glucose(FBG), serum creatinine(Cr), blood urea nitrogen(BUN) and microalbuminuria(mAlb) were measured.Masson staining, Sirius red staining and collagen type Ⅳ immunohistochemical staining were used to detect the expression of collagen protein in the cortex, while laminin staining to assess the degree of glomerular and renal tubular basement membrane thickening.The protein expressions related to epithelial-mesenchymal transition and PI3K/Akt/mTOR in the renal cortex of mice were detected by Western blot.Results The moderate and high dose of TFMF could significantly decrease the levels of FBG, Cr, BUN and mAlb in diabetic mice, meanwhile decreasing the expression of α-SMA protein by inhibiting the activation of PI3K/Akt/mTOR signaling pathway, which led to the amelioration of the pathological alterations of renal tissue.Conclusions The moderate and high dose of TFMF can reduce the level of renal interstitial fibrosis in type 1 diabetic mice, and its mechanism may be related to the inhibition of activation of PI3K/Akt/mTOR signaling pathway.

Purpose: There is no optimal prognostic model for T-cell lymphoblastic lymphoma (T-LBL). Here, we discussed the predictive value of total metabolic tumor volume (TMTV) and total lesion glycolysis (TLG) measured on 18F-fluorodeoxyglucose positron emission tomography–computed tomography (PET-CT) in T-LBL. Materials and Methods: Thirty-seven treatment naïve T-LBL patients with PET-CT scans were enrolled. TMTV was obtained using the 41% maximum standardized uptake value (SUVmax) threshold method, and TLG was measured as metabolic tumor volume multiplied by the mean SUV. Progression-free survival (PFS) and overall survival (OS) were analyzed by Kaplan-Meier curves and compared by the log-rank test. Results: The optimal cutoff values for SUVmax, TMTV, and TLG were 12.7, 302 cm3, and 890, respectively. A high SUVmax, TMTV, and TLG indicated a shorten PFS and OS. On multivariable analysis, TMTV ≥ 302 cm3, and central nervous system (CNS) involvement predicted inferior PFS, while high SUVmax, TLG and CNS involvement were associated with worse OS. Subsequently, we generated a risk model comprising high SUVmax, TMTV or TLG and CNS involvement, which stratified the population into three risk groups, which had significantly different median PFS of not reached, 14 months, and 7 months for low-risk group, mediate-risk group, and high-risk group, respectively (p < 0.001). Median OS were not reached, 27 months, and 13 months, respectively (p < 0.001). Conclusion Baseline SUVmax, TMTV, and TLG measured on PET-CT are strong predictors of worse outcome in T-LBL. A risk model integrating these three parameters with CNS involvement identifies patients at high risk of disease progression.

Objective To analyze and compare the incidence of postoperative complications of acute gangrene appendicitis after laparotomy and laparoscopic surgery.Methods This study retrospectively analyzed of 162 cases of acute gangrenous appendicitis treated in Xilin Guole Meng Hospital from January 2015 to January 2018.There were 96 male patients and 66 female patients;age (43.40 ± 16.21) years.According to different surgical methods,162 patients were divided into two groups:laparoscopic group (n =80) and open group (n =82).Laparoscopic appendectomy was performed in the laparoscopic group,and open appendectomy was performed in the open group.To compare the postoperative complications intraoperative and postoperative data between the two groups.It consists of tump fistula or bead inflammation,postoperative pneumonia,abdominal hemorrhage,deep venous thrombosis,incisional hernia,subcutaneous emphysema,incision infection,intestinal obstruction,celiac sepsis,complained of pain intensity classification method for pain score and antibiotic use time,postoperative extubation time,postoperative exhaust time,postoperative bed for the first time for the first time time,length of hospital stay.The measurement data were expressed by (Mean ± SD) and the t test was used with the groups.The counting data were expressed by the percentage or rate and the x2 test was used among the groups.When the number of single group cases was less than 10 cases,the Fisher exact probability method was used for the calibration test.Results The top three complications were incision infection,intestinal obstruction and empyema.The incidence of postoperative complications in open group and laparoscopy group was 65.9％ (54/82) and 8.8％ (7/80) respectively,and there was significant difference between the two groups (F =56.247,P=0.000).The VRS of the lapamscopic group and the open group were 53 points and 12 points for grade Ⅰ,18 points and 36 points for grade Ⅱ,and 9 points and 34 points for grade Ⅲ,The results showed that the difference between the two groups was statistically significant (x2 =2.45,P =0.01).The time of antibiotic use,postoperative tube extraction,postoperative first exhaust,postoperative first time out of bed and hospitalization in the laparoscopic group were respectively (61.2 ±24.2) d,(4.2 ± 1.2) h,(24.6 ±6.9) h,(4.6 ±2.2) h,(5.5 ±3.6) d and the open group were (72±72.6) d,(7.4 ±2.7) h,(52.2 ±4.8) h,(8.4 ±2.6) h,(13.5 ±8.2) d respectively,the differences were statistically significant (P ＜ 0.05).Conclusion The postoperative complications in laparoscopic group were lower than those in open group,so the laparoscopic group was the first choice for the treatment of acute appendicitis,while the open group was another choice for some patients.

Objective:To evaluate the efficacy of holographic image technology in robot-assisted laparoscopic radical prostatectomy (RARP).Methods:The clinical data of 34 patients with prostate cancer who underwent RARP in our hospital during October 2020 and December 2020 was analyzed retrospectively. The average age of the patients was 67.8 (52-78) years. The mean BMI was 25.8 (18.0-32.3) kg/m 2. The median level of PSA before surgery was 13.4 (2-149) ng/ml. Median prostate volume was 31.7 (9.5-159.1) ml. EAU risk groups for biochemical recurrence of localised and locally advanced prostate cancer were list as below: 5 cases of low-risk, 7 cases of medium-risk, 22 cases of high-risk. There were 9, 16, 9 cases with the ASA score of 1, 2, 3 point, respectively. Preoperative Gleason score of 34 patients were list as below: 9 cases in score ≤6 group, 15 cases in score=7 group, 10 cases in score ≥8 group. For clinical stage before the surgery, 13 cases ≤T 2a stage, 1 case in T 2b stage, 20 cases ≥T 2c stage. The engineers established holographic images of 34 patients based on multiparametric magnetic resonance imaging (mpMRI) and the reports before the operation. Surgeons can obtain the size and location of tumors, surrounding neurovascular bundles visually by revolving, assembling, disassembling and concealing images, which was helpful for pre-surgery planning. By manipulating the holographic images extracorporeally, surgeons can discriminate Internal sphincter of urinary bladder and vesicoprostatic muscle, neurovascular bundles, membranous part, seminal vesicle easily, which improves the operation accuracy. Results:All 34 cases underwent operation successfully without transferring to open surgery. The median operative time was 157.5 (95-276) min with an estimated blood loss of 50 (20-300) ml. The median drainage removal time was 2 d and median hospitalization time was 3.5 d, respectively. The catheters were removed within an average time of 20.5 d. For postoperative Gleason score, there were 2 cases in score ≤6 group, 16 cases in score =7 group, 8 cases in score ≥8 group and 8 cases can’t make a score. For clinical stage after the surgery, 10 cases were ≤T 2a stage, 1 case was T 2b stage, 23 cases were ≥cT 2c stage. 22 cases underwent pelvic lymph node dissection, including a patient with right iliac fossa lymph node metastasis. There were 2 cases with positive surgical margin and 3 cases with Clavien-DindoⅠcomplications. The rate of 1-month and 3-month urinary continence were 47.1% and79.4%, respectively, 8 cases recovered erectile function after 3 month. Conclusions:Holographic image technology can promote cancer dissection completely, achieve urinary continence early and reduce perioperative complications tremendously. The technology is the "intraoperative security" for the accurate surgical treatment of prostate cancer.

【Objective】 To investigate the clinical efficacy of preoperative therapeutic plasma exchange(TPE) in preventing acute rejection after ABO incompatible kidney transplantation(ABOi-KT). 【Methods】 Nine patients with ABOi-KT who were admitted to the renal transplant department of our hospital from April 2022 to April 2024 were retrospectively analyzed. They received a total of 28 TPEs before kidney transplantation, and the treatment plan was summarized as follows: The proportion of the substitute fluid, as well as the frequency and volume of TPE were determined based on the patient′s ABO blood group system antibody titer, gender, height, weight, hematocrit and other indicators upon admission. The patient′s relevant laboratory indicators, including hemoglobin, platelets, leukocytes, coagulation function, total protein, albumin, globulin, A/G, creatinine and urea nitrogen upon admission and after TPE were monitored and statistically analyzed. After transplantation, changes in renal function indicators such as ABO blood group system antibody titers, creatinine and urinary excretion were observed, and clinical symptoms of acute rejection, such as swelling, pain and edema in the transplanted kidney area were observed. 【Results】 Nine ABOi-KT patients had an average of about 3 TPEs before transplantation surgery, with an average total volume of approximately 2 500 mL to 3 500 mL per TPE, or approximately about 1.01 to 1.16 plasma volume (PV). After multiple TPEs, pre-transplantation antibody titers decreased by an average of 3 times compared to before TPE. There were no statistically significant differences in Hb, PLT, PT, PTA, INR, TBil, ALB, Cr and BUN (P>0.05), while statistically significant differences were found in WBC, APTT, Fbg, TP, GLB and A/G (P<0.05). After surgery, the creatinine level of 9 patients dropped to approximately 100 to 140 μmol/L, the urine output was normal, and the urine protein dropped to weakly positive or negative values. None of the nine patients experienced acute rejection. 【Conclusion】 TPE can effectively reduce the level of ABO blood group antibody and prevent the occurrence of acute rejection in ABOi-KT patients.
