Diabetic peripheral neuropathy (DPN) is the common chronic complication of diabetes, which can lead to foot ulcers, gangrene, and amputation in severe cases, seriously affecting their quality of life. DPN belongs to the category of "arthralgia", "hemorrhoids" and other categories of TCM, and the main pathogenesis is the deficiency of qi and blood, yin and yang, and the obstruction of the meridians by phlegm and stasis. Clinically, DPN is more common with qi deficiency and blood stasis syndrome. Based on the theory of "qi meridian constant communication" in the Huang Di Nei Jing, this article proposed that for patients with DPN with qi deficiency and blood stasis syndrome, the treatment should be based on the principle of "invigorating qi and activating blood circulation, dissolving stasis and arthralgia", so that the patients' qi meridian can be accessible, delay the disease progression, and provide reference for the TCM treatment of DPN.

Objective To study the efficacy of speech training combined with Montessori education on speech problems in children after velopharyngeal insufficiency surgery.Methods A retrospective analysis of 63 cases of children who underwent velopharyngeal repair at Children's Hospital of Soochow University between January 2019 and December 2021 was conducted.Subjects were divided into three groups.A total of 21 patients who received family rehabilitation training after the operation were divided into control group A,42 patients who received regular hospital rehabilitation training after the operation were divided into group B and group C,of which 21 patients in group B received routine speech training,and 21 patients in group C received Montessori education and routine speech training.Nasal resonance status,assessment of dysarthric intelligibility,and cranially positioned lateral radi-ographs when pronouncing/i/sounds were evaluated individually before treatment and 6 months after treatment.The improvement of velopharyngeal function,nasal resonance status,and dysarthric articulation were evaluated.Results After the six-month intervention,the dysarthric speech intelligibility were significantly improved in three groups with improvement of 35.45％in group A,43.66％in group B,and 49.33％in group C,respectively(P＜0.05).The improvement rate of nasality reached 100％in the B and C group with nasality elimination rate of 70％in group B and 95.24％nasality elimination in group C,and the efficacy of the two groups was statistically signifi-cant(P＜0.05).During phonation of the/i/tone,velopharyngeal insufficiency was observed in seven patients in group B and in only one patient in group C,and the efficacy was statistically significant in both groups(P＜0.05).Conclusion Postoperative targeted speech training is necessary in patients with velopharyngeal insufficiency,and speech training combined with Montessori education can significantly improve the function of velopharyngeal clo-sure,thus achieving a good state of nasal resonance and correct articulation as early as possible.

Objective To investigate the effect of dexmedetomidine on renal function in patients with septic-associated acute kidney injury(SAKI).Methods A prospective cohort study was conducted in 180 patients with sepsis admitted to ICU in the Second Affiliated Hospital of Guangdong Medical University from October 2021 to April 2023.According to the principle of randomized controlled trials,60 non-acute kidney injury(AKI)patients were divided into S-D group(n = 30,dexmedetomidine + conventional treatment)and S group(n = 30,conventional treatment),and the occurrence and disease score of AKI after treatment were compared between the two groups.A total of 120 AKI patients were divided into SA-D-RT group(n = 30,dexmedetomidine + blood purification + conven-tional treatment),SA-D group(n = 30,dexmedetomidine + conventional treatment),SA-RT group(n = 30,blood purification + conventional treatment)and SA group(n = 30,conventional treatment).Renal function,inflammatory factor level and disease change of the four groups were compared after treatment.Results After treatment,the inci-dence of AKI in S-D group was lower than that in S group,and the APACHEII score and SOFA score in S-D group were lower than those in S group on the 7th day after treatment(P<0.05).After 7 days of treatment,the level of Scr,BUN and CysC in the 4 groups was significantly lower than that on the 1st and 3rd day,and those in the SA-D-RT group were lower than those in the SA-D group,SA-RT group and SA group(P<0.05).After 7 days of treatment,the level of CRP,PCT,TNF-α,IL-6 and IL-1β in four groups was significantly decreased compared with on the 1st and 3rd day,and the level of CRP,PCT,TNF-α,IL-6 and IL-1β in SA-D-RT group was lower than that in SA-D group,SA-RT group and SA group(P<0.05).After 7 days of treatment,the APACHEII score and SOFA score of the four groups were significantly lower than on the 1st and 3rd day,and the scores of the SA-D group were lower than those of the SA-D group,the SA-RT group and the SA group(P<0.05).Conclusion Dexmedetomidine can effectively reduce the incidence of AKI,affect the expression level of renal function markers and inflammatory factors in serum of SAKI patients,and improve the condition of patients.

ObjectiveTo observe the effect of aerobic exercise on core symptoms and executive function in children with attention deficit hyperactivity disorder (ADHD). MethodsFrom June, 2020 to December, 2021, 64 children with ADHD at outpatient in Dushu Lake Hospital were randomly divided into control group (n = 32) and observation group (n = 32). The control group sat down and watched the cartoon for 20 minutes, and the observation group performed cycling exercise while watching the cartoon, for twelve weeks. The core symptoms were assessed with Conners Parent Symptom Questionnaire (PSQ), while the inhibition, conversion and refresh functions were assessed with the psychological test software E-Prime 2.0 system. ResultsAfter twelve weeks of treatment, the PSQ factor scores decreased in the observation group (t > 4.775, P < 0.001), and were lower than that of the the control group (t > 3.184, P < 0.001). The response time and accuracy of inhibition, conversion, and refresh functions decreased in the observation group (t > 2.259, P < 0.05), and were lower than that of the control group (t > 2.007, P < 0.05). ConclusionAerobic exercise could reduce the core symptoms of poor attention and hyperactivity impulsivity, and improve the executive functioning in children with ADHD.

Changes in structure of oral solid dosage forms (OSDF) elementally determine the drug release and its therapeutic effects. In this research, synchrotron radiation X-ray micro-computed tomography was utilized to visualize the 3D structure of enteric coated pellets recovered from the gastrointestinal tract of rats. The structures of pellets in solid state and in vitro compendium media were measured. Pellets in vivo underwent morphological and structural changes which differed significantly from those in vitro compendium media. Thus, optimizations of the dissolution media were performed to mimic the appropriate in vivo conditions by introducing pepsin and glass microspheres in media. The sphericity, pellet volume, pore volume and porosity of the in vivo esomeprazole magnesium pellets in stomach for 2 h were recorded 0.47, 1.55 × 10⁸ μm³, 0.44 × 10⁸ μm³ and 27.6%, respectively. After adding pepsin and glass microspheres, the above parameters in vitro reached to 0.44, 1.64 × 10⁸ μm³, 0.38 × 10⁸ μm³ and 23.0%, respectively. Omeprazole magnesium pellets behaved similarly. The structural features of pellets between in vitro media and in vivo condition were bridged successfully in terms of 3D structures to ensure better design, characterization and quality control of advanced OSDF.

Objective:To observe the effect of Tangtong formula on the expression of autophagy pathway proteins PI3K, Akt and mTOR in sciatic nerve of DPN rats, and to explore its mechanism. Methods:There were 60 male SD rats, 15 of which were randomly selected as the normal group, and the other rats were used to establish DPN model with STZ + ischemia-reperfusion method. Then they were divided into model group, Tangtong formula low-dose group and Tangtong formula high-dose group, with 15 rats in each group with random number table method. 36.67 g/kg Tangtong formula was administered by gavage in the high-dose group and 18.33 g/kg Tangtong formula was administered by gavage in the low-dose group, once a day. After 8 weeks of continuous gavage, the conduction velocity of sciatic nerve was detected. The mRNA and protein expression levels of PI3K, Akt and mTOR were detected by PCR and Western blot. The structure of sciatic nerve fibers was observed by HE staining. Results:Compared with the model group, the motor nerve conduction velocity, sensory nerve conduction velocity, muscle compound action potential and sensory nerve action potential in the low-dose Tangtong formula group and high-dose Tangtong formula group were increased ( P<0.05). The expression of PI3K mRNA(6.05±0.18, 3.36±0.29 vs. 11.57±1.93), Akt mRNA(1.26±0.13, 0.64±0.04 vs. 1.86±0.06), mTOR mRNA(1.82±0.11, 0.92±0.06 vs. 2.68±0.18) of sciatic nerve in rats of the low-dose and high-dose group were increased ( P<0.05). The expression of PI3K(0.40±0.00, 0.19±0.02 vs. 0.61±0.03), Akt(0.64±0.02, 0.45±0.01 vs. 0.83±0.02), mTOR(0.17±0.01, 0.09±0.00 vs. 0.34±0.01)of sciatic nerve in rats of the low-dose and high-dose group were increased ( P<0.05). The model group's nerve fibers were loose and swollen, myelin sheath became thin, and the axis Atresia, the neuromorphology of the low-dose and high-dose group tended to be normal, and the morphology of myelin sheath and axon were better. Conclusions:Tangtong formula could improve the conduction velocity and potential amplitude of sciatic nerve in DPN rats, reduce nerve injury and demyelinating changes, improve axon morphology and protect nerve fiber structure. Its mechanism might be related to activating PI3K/Akt/mTOR signal pathway and inhibiting excessive autophagy.

Objective:To investigate the dynamic changes of mitochondrial fission and fusion in the heart of cardiac arrest (CA) rats after return of spontaneous circulation (ROSC), and to explore the role of mitochondrial fission and fusion in the myocardial injury after ROSC.Methods:Healthy male SD rats were randomly random number assigned into the post-resuscitation (PR) 4 h ( n=12), PR 24 h ( n=12), PR 72 h ( n=12), and sham groups ( n=6). The rat CA model was induced by asphyxia, and cardiopulmonary resuscitation (CPR) was performed 6 min after CA. The protein expressions of mitochondrial Drp1, Fis1, Mfn1, and Opa1 were determined by Western blot in each group at 4, 24 and 72 h after ROSC. The mRNA expressions of Drp1, Fis1, Mfn1, and Opa1 were determined by RT-PCR. Myocardial ATP content and mitochondrial respiratory function were measured. The histopathologic changes of myocardial tissue were observed under light microscope. One-way analysis of variance (ANOVA) was use to compare quantitative data, and LSD- t test was used for comparison between groups. Results:Compared with the sham group, the protein and mRNA expressions of Drp1 and Fis1 were increased (all P<0.05) and the protein and mRNA expressions of Mfn1 and Opa1 were decreased (all P<0.05) in the PR 4 h and PR 24 h groups. However, there were no statistical differences in the protein and mRNA expressions of Drp1, Fis1, Mfn1, and Opa1 in the PR 72 h group compared with the sham group (all P>0.05). Compared with the sham group, the levels of ATP content [(4.53±0.76) nmol/g protein vs. (8.57±0.44) nmol/g protein and (5.58±0.58) nmol/g protein vs. (8.57±0.44) nmol/g protein] and mitochondrial respiratory control rate [(2.47±0.38) vs. (3.45±0.32) and (2.97±0.24) vs. (3.45±0.32)] were obviously decreased in the PR 4 h and PR 24 h groups (all P<0.05). There were no statistically significant differences in the ATP content [(7.73±0.95) nmol/g protein vs. (8.57±0.44) nmol/g protein] and mitochondrial respiratory control ratio [(3.39±0.34) vs. (3.45±0.32)] between the PR 72 h group and the sham group (all P>0.05). The pathological damage of myocardial tissue was obvious in the PR 4 h group, and was improved significantly in the PR 72 h group. Conclusions:The imbalance of mitochondrial fission and fusion is probably involved in the pathological process of myocardial injury after ROSC, which may be related to mitochondrial dysfunction.

Objective:To explore the risk factors of thyroid nodules in diabetic patients and its correlation with Traditional Chinese Medicine (TCM) constitution.Methods:A Total of 213 cases of diabetic patients in Guang’anmen Hospital and Tangshan Hospital from January 2019 to August 2020 were choosen to do the questionnaire, with containly symptom and constitution. The patients were divided into diabetes with thyroid nodules group and diabetes without thyroid nodules group according to whether thyroid nodules were combined. We compared the clinical data characteristics of 2 groups, and used multi-factor logistic regression model to analyze the risk factors of diabetic patients with thyroid nodules and their correlation with TCM constitutions. Results:Diabetes patients aged from 50-80 years old [ OR=2.949, 95% CI (1.266-6.714)], females [ OR=3.736, 95% CI (1.823-1.541)], diabetes duration≥15 years [ OR=1.558, 95% CI (1.623-1.585)], elevated HbA1c [ OR=5.862, 95% CI (1.418-23.629)], elevated VLDL [ OR=2.851, 95% CI (1.597-6.824)], frequent insomnia [ OR=1.970, 95% CI (1.315-3.395)], Qi stagnation [ OR=4.357, 95% CI (2.634-8.377)], blood stasis [ OR=4.420, 95% CI (1.874-15.258)] are more likely to suffer from thyroid nodules ( P<0.05). Conclusion:Diabetic patients aged from 50-80 years old, females, diabetes duration≥15 years, elevated HbA1c, family history of thyroid nodules, frequent insomnia, and mood swings are more likely to develop thyroid nodules; qi stagnation and blood stasis are dangerous constitutions for diabetic patients with thyroid nodules.

Objective:To retrospectively analyze the influencing factors during the hospitalization of premature infants in the neonatal intensive careunit (NICU) based on the breast-feeding choices of the primary family caregivers of premature infants discharged from NICU.Methods:According to the breast-feeding status of 342 premature infants discharged from the NICU from The First hospital of Jilin University from June 1st, 2019 to December 31th, 2019, a self-designed data collection form for premature infants was used to investigate them, and the influencing factors of NICU hospitalization on breast-feeding selection were retrospectively analyzed.Results:The factors influencing breastfeeding included gestational age ( tvalue was-2.177, P=0.029), birth weight ( tvalue was-2.036, P=0.043), feeding mode during hospital stay ( χ2value was 6.582, P=0.010), length of hospital stay ( Zvalue was-2.205, P=0.027), maternal age ( Zvalue was-2.975, P=0.003), maternal education level ( χ2value was 8.350, P=0.04) and twin pregnancy ( χ2value was 7.367, P=0.007). The results of multivariate Logistic regression analysis showed that breast-feeding during hospitalization ( P=0.003) and older age of the mother ( P<0.001) were favorable factors to promote breast-feeding. Twin pregnancy ( P=0.006), low maternal education ( P=0.001) and gestational age ( P=0.006) were the risk factors that were not conducive to the implementation of breastfeeding. Conclusion:During the hospital period, the implementation of breastfeeding and the old age of the mother are conducive to the choice of breastfeeding after discharge, while twin pregnancy, low education of the mother and premature infants of large gestational age are not conducive to the implementation of breastfeeding.

Objective:To explore the effect of the implantation of absorbable stents on the prognosis of patients with inferior knee artery balloon dilatation.Methods:From March 2018 to January 2021, twenty-five patients with drug absorbable stent implantation after inferior knee artery balloon dilatation (stent group) and 25 patients without absorbable stent implantation after inferior knee artery balloon dilatation (control group) were included in Qingdao Haici Medical Group Affiliated to Qingdao University. The improvement of symptoms, ankle brachial index, Rutherford classification and claudication distance before and after operation were compared. The symptoms, ankle brachial index, Rutherford grade, claudication distance and patency rate of the two groups were compared 6 months after operation. The preoperative and postoperative data were analyzed by independent sample t-test, and the patency rate was analyzed by χ 2 test. Results:The ankle brachial index in the stent group and the control group on the first day after operation was significantly higher than that before operation (0.18±0.11 vs. 0.85±0.15, t=18.5, P<0.05, 0.22±0.15 vs. 0.87±0.10, t=20.8, P<0.05), and the Rutherford classification decreased significantly (4.66±0.21 vs. 2.1±0.11, t=9.2, P<0.05, 4.58±0.33 vs. 2.3±0.22, t=12.9, P<0.05), the limp distance increased significantly ((27±8) m vs. (300±43) m, t=20.8, P<0.05, (42±14) m vs. (320±18) m, t=32.6, P<0.05). There was no significant difference in preoperative ankle brachial index, postoperative ankle brachial index, Rutherford grade and claudication distance between the two groups ( P>0.05). Six months after operation, the ankle brachial index (0.72±0.03 and 0.54±0.12; t=10.2, P<0.05), Rutherford classification ((1.72±0.17) and (3.23±0.22); t=12.8, P<0.05) and claudication distance ((580.00±137.00) m and (267.00±54.00) m; t=8.2, P<0.05) in the stent group and the control group were significantly better than those in the control group. The patency rate of stent group at 6 months was 68% (17/25), which was better than that of ordinary balloon dilatation group by 56% (14/25). Conclusion:Implantation of drug absorbable stents can significantly improve the prognosis of patients undergoing arterial balloon dilatation.
