ObjectiveTo observe the effect of tendon clearing combined with Zizhu ointment on the serum levels of nucleotide-binding oligomerization domain-like receptor protein 3 （NLRP3） inflammasomes， interleukin （IL）-1β， and IL-18 in the treatment of non-ischemic diabetic foot ulcers. MethodA total of 106 patients with non-defective diabetic foot ulcers who attended the outpatient clinic and wards of the Vascular Surgery Department of Shuguang Hospital affiliated to Shanghai University of Traditional Chinese Medicine from March 2023 to March 2024 were selected. The patients with non-ischemic diabetic foot ulcers who met the inclusion criteria were assigned with the random number table method into an observation group and a control group， with 53 patients in each group. Patients in both groups received basic treatment. The local ulcers in the observation group received tendon clearing combined with Zizhu ointment， while those in the control group received conventional debridement combined with topical solution of bovine basic fibroblast growth factor. The serum NLRP3， IL-1β， and IL-18 levels， ulcer area， traditional Chinese medicine （TCM） symptom scores， visual analogue scale （VAS） score， and DMIST score were measured and recorded in the two groups before and after treatment. The ulcer healing rate and incidence of adverse reactions were compared between the two groups. ResultThe observation group had higher ulcer healing rate than the control group （P<0.01）. After treatment， both groups showed lowered serum NLRP3， IL-1β， and IL-18 levels， reduced ulcer area， and declined TCM symptom score， VAS score， and DMIST score （P<0.01）. Moreover， these indicators were lower in the observation group than in the control group （P<0.05， P<0.01）. Neither group showed significant changes in the liver and kidney function indicators after treatment. Significant adverse reactions occurred in neither group during the treatment course. ConclusionTendon clearance combined with Zizhu ointment was effective and safe in treating non-ischemic diabetic foot ulcers. It may exert the therapeutic effect by reducing the inflammation of the local ulcers.

BACKGROUND: Corneal confocal microscopy (CCM) is a noninvasive technique to detect early nerve damage of diabetic sensorimotor polyneuropathy (DSPN). Time in range (TIR) is an emerging metric of glycemic control which was reported to be associated with diabetic complications. We sought to explore the relationship between TIR and corneal nerve parameters in asymptomatic patients with type 2 diabetes (T2DM). METHODS: In this cross-sectional study, 206 asymptomatic inpatients with T2DM were recruited. After 7 days of continuous glucose monitoring, the TIR was calculated as the percentage of time in the glucose range of 3.9 to 10.0 mmol/L. CCM was performed to determine corneal nerve fiber density, corneal nerve branch density, and corneal nerve fiber length (CNFL). Abnormal CNFL was defined as ≤15.30 mm/mm 2 . RESULTS: Abnormal CNFL was found in 30.6% (63/206) of asymptomatic subjects. Linear regression analyses revealed that TIR was positively correlated with CCM parameters both in the crude and adjusted models (all P   <  0.05). Each 10% increase in TIR was associated with a 28.2% (95% CI: 0.595-0.866, P  = 0.001) decreased risk of abnormal CNFL after adjusting for covariates. With the increase of TIR quartiles, corneal nerve fiber parameters increased significantly (all P for trend <0.01). The receiver operating characteristic curve indicated that the optimal cutoff point of TIR was 77.5% for predicting abnormal CNFL in asymptomatic patients. CONCLUSIONS There is a significant independent correlation between TIR and corneal nerve fiber loss in asymptomatic T2DM patients. TIR may be a useful surrogate marker for early diagnosis of DSPN.

Objective To observe the clinical efficacy ofXing Nao Kai Qiao(brain-awakening orifice-opening) needling method plus Frenkel's balance rehabilitation exercise in treating lower-limb dysfunction due to different types of ataxia after stroke.MethodA total of 115 eligible patients were randomized into two groups. Fifty-seven cases in the treatment group were intervened by Xing Nao Kai Qiaoneedling plus rehabilitation training; 58 cases in the control group were intervened byXing Nao Kai Qiaoneedling method alone. Berg Balance Scale (BBS) was adopted to evaluate the symptoms, balance function, and therapeutic efficacy before and after the treatment.Result In the treatment group, the markedly effective rate was respectively 72.2%, 83.3% and 61.1% in the cerebella subtype, brainstem subtype and basal ganglia subtype, and the total effectiverate was respectively 100.0%, 94.4% and 94.4%; in the control group, the markedly effective rate was respectively 21.1%, 35.0% and 58.8%, and the total effective rate was respectively 94.7%, 85.0% and 82.4%, and the between-group differences were statistically significant (P<0.05). After the treatment, the BBS score showed significant intra-group differences in both groups (P<0.01); the between-group comparisons showed that there were significant differences in comparing the scores of cerebella and brainstem subtypes after the treatment (P<0.05).ConclusionXing Nao Kai Qiaoneedling method plus Frenkel's rehabilitation exercise can effectively improve the symptoms of poststroke lower-limb ataxia, especially for cerebella and brainstem subtypes.

To construct soluble TNF related apoptosis inducing ligand (TRAIL) expression system and investigate the effect of the expression product on tumor cell. It may provide valuable information for research into the immune system of the finless porpoise. The full-length cDNA of TRAIL (designated fTRAIL) was cloned from the total RNA of the finless porpoises blood using RT-PCR techniques and then the extracellular soluble fragments of fTRAIL (designated fsTRAIL) was ligated into pET43.1a. Recombinant soluble fTRAIL (pET43.1a-fsTRAIL) fused with Nus-his tag was efficiently expressed in Escherichia coli BL21 (DE3) and the Nus-His-fsTRAIL protein was purified. The expression of Nus-His-fsTRAIL was verified by Western blotting. In vitro, the effects of the purified Nus-His-fsTRAIL protein on Jurkat and HeLa cells were etected by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrasodium bromide (MTT) assay, TrypanBlue and Flow Cytometry analysis. The expression system pET43.1a-fsTRAIL was constructed and Nus-His-fsTRAIL protein was expressed successfully. In vitro, the Nus-His-fsTRAIL protein was able to inhibit the proliferation and induce apoptosis of Jurkat and HeLa cells in a dose-dependent manner. The Nus-His-fsTRAIL protein has anti-tumor activity against Jurkat and HeLa cells in vitro.

Objective To analyze the clinical characteristics and recent curative effect of mantle cell lymphoma (MCL) after conventional treatment.Methods Clinical data of 15 MCL patients admitted in the Affiliated Hospital of Academy of Military Medical Sciences between August 2004 and October 2013 were retrospectively analyzed.Results The median age of those patients was 59 and the male to female ratio was 1.5∶1.Fourteen(93%)cases were in Ann-Arbor stages Ⅲ -Ⅳ, 15 cases (100%)primarily with lymph node involvement,7 cases (47%)with bone marrow involvement,4 cases (27%)with gastrointestinal involvement,and 3 cases (20%)with orbit involvement.Less than 40% expression of Ki-67 was observed in 9 cases (60%),while 6 cases were with more than 40% (40%).One case was blastic variant.First-line therapy was CHOP-like regimens,which were combined with rituximab in 8 of the 15 cases.In this study,the median survival time was 12 months (3 -64),and the overal response rate was 80%after induction chemotherapy.The current survival of 7 /9 cases with less than 40% expression of Ki-67 was 8 -64 months,2 /6 cases with more than 40% expression of Ki-67 was 8 and 9 months,respectively.Conclusion MCL mostly occurs in older males.Extranodal invasion is common in MCL as an aggressive tumor.The efficacy of traditional chemotherapy is currently limited.Blastic variant or high expression of Ki-67 is an adverse prognostic indicator.

Objective:The effect and side effect of the dose-adjusted EPOCH regimen were evaluated perspectively for the pre-liminarily diagnosed angioimmunoblastic T-cell lymphoma. Methods: Nine cases of untreated angioimmunoblastic T-cell lymphoma were diagnosed and enrolled in our department from September 2008 to September 2012. All patients received dose-adjusted EPOCH regimen as first-line chemotherapy. Results: The median age of 9 patients was 54 years. The male-to-female ratio was 2∶1. About 88.9%of all patients were at Ann Arbor stageⅢ/Ⅳ, and 77.8%presented with B symptoms. Anemia was found in 66.7%of 9 patients, and lactate dehydrogenase elevated in 55.6%of patients. After an average of 4.7 cycles of chemotherapy of dose-adjusted EPOCH regi-men, the complete remission rate was 22.2%, and the total response rate was 66.7%. With a median follow-up of 20 months, the 4-year progression-free survival rate was 11.1%, and the overall survival rate was 33.3%. The median survival time was 19 months. The most common adverse events of EPOCH chemotherapy were hematologic toxicity. Grades 3-4 neutropenia and thrombocytopenia were re-ported in 77.8%and 33.3%of patients. Febrile neutropenia was observed in 44.4%of patients. Non-treatment-related mortality was al-so noted. Conclusion: The results of our research showed no clear benefit of treating preliminarily diagnosed angioimmunoblastic T-cell lymphoma with dose-adjusted EPOCH regimen. The main adverse events were hematologic toxicity and could be tolerated.

Objective To study the early and mid-term outcome in terms of left ventricular(LV)geometry and function in patients with transposition of great arteries with intact ventricular septum (TGA/IVS) undergoing arterial switch operation.Methods Twenty patients were followed up and divided into 2 groups according to age:the earlier group and the later group.Age and sexual matched controls were also designed as control group 1 and control group 2.LV posterior wall thickness(PWTd),dimension(LVIDd)and length(L) at end diastolic phase,LV end-diastolic volume (EDV),end-systolic volume (ESV),ejection fraction (EF),mitral valve early (E) and late (A) inflow velocities and E/A,isovolumic relaxation time (IVRT) were obtained by two-dimensional echocardiography,normalized isovolumic relaxation time (IVRTn),wall thickness index (PWTd/LVIDd) and LV geometry index(LVIDd/L) were calculated,and these indexes between groups were compared.Results ①Compared with control group 1,PWTd in earlier group was higher [(0.41 + 0.06)cm vs (0.36 + 0.05)cm,P =0.022],but LVIDd had no significant statistical difference [(2.08 + 0.21)cm vs (2.21 + 0.23)cm,P =0.117],indicating PWTd/ LVIDd differed between groups(0.20 + 0.04 vs 0.16 + 0.01 P =0.001).②No abnormalities were observed in later group.③Compared with different age groups in TGA,EDV,ESV,L,LVIDd,PWTd were significantly higher in later group(P =0.000).There were obvious correlations between EDV,ESV,L,LVIDd and examined age (r =0.90,0.83,0.73,0.90,P =0.000,R2 =0.809,0.694,0.528,0.808) while there were no significant correlation between PWTd and examined age(r =0.56,P =0.000,R2 =0.309).Conclusions Early after operation,LV is undergoing hypertrophy or hyperplasia in TGA/IVS,but will recover in the mid-term period,and the function is normal all the time indicating that the LV myocardium may avoided irreversible pathological changes if operated in time.All in all,LV develops well in mid-term period.

This study was designed to observe the negative pressure in the cup during cupping, and to investigate the influence of negative pressure on the depth of filiform-needle inserted and retained. In the beginning, the change of pressure after cupping on acupoint BL23 for a span of 20 minutes was recorded. Acupuncture on acupoint BL23 was performed; the filiform-needle was retained and followed by cupping at different levels of negative pressure, and the changes of the depth of needle insertion was measured. The results showed: the absolute value of the negative pressure in the cup goes down with time and is significantly lower after 20 minutes (P < 0.05); the negative pressure in the cup causes the retreat of the inserted needle; and under the same pressure, there is a greater length measurement in needle retreat for male than for female (P < 0.01). The length of needle retreat is related to the pressure in the cupping-cup and to gender.

To investigate the potential of gene therapy for the treatment of chronic diseases such as hypertension, chronic heart failure, and chronic renal failure, we established the neonatal rat fibroblast line engineered to secrete the mutant human atrial natriuretic peptide (mhANP), and then transplanted the cell line into young spontaneously hypertensive rats (SHR) subcutaneously. We found that a single transplantation of the cell line caused an obvious rise in the concentration of mhANP in serum 7 d after transplantation ((135 +/- 8) vs (106 +/- 7) pg/mL, P < 0.01). The animals' blood pressure in test group was always remarkably lower than that of empty vector group within 42 d after transplantation, even though the blood pressure in all groups was constantly increasing in the process of ontogeny ((175 +/- 10) mm Hg vs (189 +/- 12) mm Hg, P < 0.05). A maximal blood pressure reduction of 33 mm Hg ((157 +/- 9) mm Hg vs (124 +/- 112) mm Hg, P < 0.01) was observed 14 d post cell transplantation. There was a marked increase in urine volume in test group from second week after treatment beginning ((5.9 +/- 0.7) mL/6 h vs (4.3 +/- 0.8) mL/6 h, P < 0.01) and the effect lasted 14 d ((6.1 +/- 1.1) mL/6 h vs (4.0 +/- 0.8) mL/6 h, P < 0.01), however the statistical difference in concentration of K+ and Na+ in serum and urine was not observed. The results suggested that subcutaneous implantation of fibroblasts-expressing mhANP significantly reduced blood pressure in young SHR during the period of ontogeny and efficiently improved their renal function and the somatic gene transfer of mhANP may have potential value in the treatment of human chronic diseases such as hypertension, chronic heart failure, and chronic renal failure.
