OBJECTIVE: To reveal the gap between the evidence of systematic reviews (SRs) and clinical concerns by systematically summarizing the evidence on acupuncture and moxibustion for frozen shoulder and investigating the concerns and needs of clinicians in treatment with acupuncture and moxibustion for this disease. METHODS: The articles of SR and Meta-analysis on acupuncture and moxibustion for frozen shoulder were searched from CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase and Cochrane Library, starting from the inception of each database up to December 31st, 2022. Two researchers screened the articles and extracted data independently. Using AMSTAR-2, the methodological quality of the included studies was evaluated. Based on systematic reviews and expert discussion, a questionnaire on clinical concerns of acupuncture and moxibustion for frozen shoulder was developed and distributed to clinicians. The discrepancies between the evidence and clinical concerns were compared from 5 dimensions, including population, interventions, control measures, outcome indicators and review time points. RESULTS: The evidence gaps existed between SRs and clinical concerns. In the existing studies, the needs of personalized treatment were not fully considered in terms of different syndromes/patterns of frozen shoulder and stages of illness, the outcome indicators were not employed properly, the time for outcome measurement was vague, the control groups were set up outside of standardization, and the methodological quality was lower. CONCLUSION It is suggested that future studies should improve the quality of methodology, lay more consideration to different patient groups, optimize outcome indicators and standardize the setting of control groups, so as to better meet the needs of patients and achieve the best match between evidence and clinicians' needs.

The paper reports one case of primary cutaneous amyloidosis (PCA) treated by tapping with plum-blossom needle combined with sulfur ointment and local irradiation. PCA in this case was manifested as generalized erythema, papules, plaques, lichenification, and severe pruritus. In treatment, tapping with plum-blossom needle was delivered at typical lesions to induce local congestion, redness, and minimal bleeding. After cleaned with sterile gauze for 10 s, 25% sulfur ointment was evenly applied, followed by local irradiation with a TDP lamp for 15 min. This session was repeated twice a week. In 1 month of treatment, the lesions turned flat and the skin was soft as the normal, with pigmentation and mild pruritus left. In 3 months of follow-up, no papules recurred, and mild pruritus presented occasionally.

Objective To investigate the diagnostic value of our regression model based on quantitative parameters of dual-energy CT and clinical features for stages T2 and T3 colorectal cancer.Methods A cross-section study was performed on 91 patients with colorectal cancer confirmed by postoperative pathology in our hospital from January 2022 to November 2023.All of them underwent dual-energy CT examination.According to the pathological T staging criteria of Chinese Colorectal Cancer Diagnosis and Treatment Standard(2020 Edition),they were divided into T2 group(n=43)and T3 group(n=48).Univariate analysis was used to compare the differences in quantitative CT parameters and clinical features between the 2 groups,and the obtained significant variables were employed to construct diagnosis models by univariate or multivariate logistic regression analysis.The area under receiver operating characteristic curve(AUC)of the CT parametric model and the model combined with clinical features was compared to evaluate the efficacy of diagnosing T2 and T3 stages.Results Univariate analysis showed that carcinoembryonic antigen(CEA),N stage,tumor location,tumor longest diameter(LD),CT value of virtual noncontrast(CT-VNC),fat fraction,electron density(Rho)and dual energy index(DEI)were significantly different between the T2 and T3 groups(P＜0.05).Multivariate logistic regression analysis found that N stage,tumor location,LD,fat fraction and DEI were independent risk factors for the diagnosis of stage T3.The AUC value of the model of above CT parameters in diagnosing stage T3 colorectal cancer was 0.671(95％CI:0.558～0.783),and the AUC value of the combined model of above CT parameters and clinical features was 0.886(95％CI:0.815～0.957),and statistical difference was observed in the AUC value between the combined model and the CT parametric model(P＜0.01).Conclusion The regression model constructed with dual-energy CT quantitative parameters combined with clinical features has high value in the preoperative diagnosis of stages T2 and T3 colorectal cancer before surgery.

AIM:To explore the effect of sinomenine hydrochloride(SH)on microcirculation and renal func-tion in type 2 diabetic db/db mice with a focus on the diacylglycerol(DAG)/protein kinase C(PKC)signaling pathway.METHODS:Eighteen 6-week-old male db/db mice were randomly divided into three groups:model group(saline),LY group(administered with 1 mg·kg-1·d-1 LY333531),and SH group(administered with 124.8 mg·kg-1·d-1 SH).Addi-tionally,6 age-matched db/m mice comprised the control group(saline).Daily intragastric administration lasted 6 weeks.Body mass,fasting blood glucose(FBG),urinary microalbumin(mALB),urinary creatinine(UCr)and urinary β2-micro-globulin(β2-MG)were measured in each group.The serum levels of endothelin-1(ET-1),endothelial nitric oxide syn-thase(eNOS),collagen type Ⅳ(Col Ⅳ)and laminin(LN),and the levels of DAG and PKC in renal tissues were ana-lyzed by enzyme-linked immunosorbent assay(ELISA).The morphological changes of renal tissues were assessed using HE and PAS staining,and kidney ultrastructure was examined via transmission electron microscopy.Immunohistochemis-try and Western blot were used to detect PKC and p-PKC levels in renal tissues.RESULTS:Compared with model group,the mice in both LY and SH groups showed decreased body mass(P＜0.05),with significantly reduced FBG level in LY group(P＜0.01).In addition,the urinary mALB and β2-MG levels were markedly decreased(P＜0.01),while UCr level was significantly increased(P＜0.01).Serum ET-1,Col Ⅳ and LN levels were significantly lower(P＜0.01),whereas eNOS level was notably higher(P＜0.01).Renal tissue DAG and PKC levels,as well as p-PKC expression were significantly reduced(P＜0.01).Improvements in renal tissue pathology and ultrastructure were observed.CONCLU-SION:Sinomenine hydrochloride improves microcirculation in diabetic db/db mice by modulating DAG/PKC signaling pathway,thus exerting protective effect on the kidney.

AIM:To investigate the mechanism by which exosomes(EXOs)derived from neural stem cells(NSCs)pretreated with astragaloside IV(ASIV)alleviate brain damage in rats after ischemic stroke.METHODS:Rat NSCs were isolated from fetal rats within 24 h of birth,cultured for 3 d,and subsequently treated with ASIV for additional 5 d.The EXOs from untreated NSCs and ASIV-pretreated NSCs(ASIV-EXOs)were isolated via ultracentrifugation of the cell supernatant.These EXOs were characterized using Western blot to detect specific markers such as CD63,tumor sus-ceptibility gene 101(TSG101)and calnexin.Nanoparticle analysis was employed to determine the size,and the morpholo-gy of the EXOs was observed under electron microscope.Six to eight-week-old SD male rats were randomly assigned to 6 groups:sham group,middle cerebral artery occlusion/reperfusion(MCAO/R)model group,edaravone(EDA)treatment(MCAO/R+EDA)group,EXOs treatement(MCAO/R+EXOs)group and ASIV-EXOs treatment(MCAO/R+ASIV-EXOs)group.Tail vein injections were administered within 2 h following the successful establishment of the MCAO/R model.The Zea Longa method was utilized to evaluate neurological deficits,while the TTC method was employed to assess brain infarc-tion.Pathological changes were examined through HE staining,and TUNEL and caspase-1 immunofluorescence double staining were conducted to detect cellular pyroptosis.Serum levels of interleukin-1β(IL-1β)and IL-18 were measured us-ing ELISA,and Western blot was performed to evaluate the expression of caspase-1,nucleotide-binding oligomerization domain-like receptor protein 3(NLRP3),apoptosis-associated speck-like protein containing a caspase recruitment domain(ASC),gasdermin D(GSDMD),and IL-18 proteins in the ischemic area of the rat cerebral cortex across all groups.RE-SULTS:The MCAO/R group exhibited significantly higher neurological deficit scores compared to the sham group(P＜0.01)and lower scores in the administered groups relative to the MCAO/R group(P＜0.05).Cerebral infarction was mark-edly increased in the MCAO/R group compared to the sham group(P＜0.01),whereas the infarction area was reduced in the administered groups compared to the MCAO/R group(P＜0.05).Serum levels of IL-1β and IL-18 were significantly el-evated in the MCAO/R group versus the sham group(P＜0.01)and were lower in the administered groups compared to the MCAO/R group(P＜0.01).Moreover,IL-1β and IL-18 levels in the MCAO/R+ASIV-EXOs group were lower than those in the MCAO/R+EXOs group(P＜0.05).HE staining revealed pronounced sieve-like infarction foci in the ischemic area of the rat cerebral cortex in MCAO/R group,characterized by disorganized neuronal arrangements,reduced or absent Nys-trom's vesicles,shrunken or fragmented nuclei,and numerous red neurons.In contrast,drug-treated groups exhibited milder pathological changes with clearer neuronal structures and a significant reduction in red neuron counts.Immunofluo-rescence double staining indicated a significant increase in double-positive cells in the MCAO/R group compared to the sham group(P＜0.01),with a decrease in double-positive cells in the administered groups relative to the MCAO/R group(P＜0.05)and a further reduction in the MCAO/R+ASIV-EXOs group compared to the MCAO/R+EXOs group(P＜0.05).The expression levels of caspase-1,NLRP3,ASC,IL-18 and GSDMD proteins in the ischemic region of the rat cerebral cortex were significantly reduced in the administered groups compared to the MCAO/R group(P＜0.01),with further re-duction observed in the MCAO/R+ASIV-EXOs group compared to the MCAO/R+EXOs group(P＜0.05).CONCLU-SION:Exosomes derived from ASIV-pretreated NSCs attenuate brain damage in ischemic stroke rats,potentially through a mechanism involving the inhibition of pyroptosis mediated by the NLRP3/caspase-1 pathway.

AIM:This study aimed to investigate the effects of sinomenine hydrochloride(SIN)on the ultra-structure of renal tissue and the expression of interferon gene-stimulating factor in db/db mice.METHODS:Sixteen 12-week-old male db/db mice were randomly divided into two groups:a model group and a sinomenine hydrochloride(SIN)group,each consisting of 8 mice.An additional 8 wild-type(WT)mice served as the normal control group.The sinome-nine hydrochloride group was administered the treatment for 8 weeks,followed by a 20-week observation period,while the normal and model groups received an equal volume of saline via gavage.Weekly measurements were taken for body weight and fasting blood glucose.Serum creatinine(SCr)and blood urea nitrogen(BUN)levels were assessed,and 24-hour uri-nary microalbumin(ALB)levels,as well as serum inflammatory cytokines interleukin-1β(IL-1β),IL-6 and tumor necro-sis factor-α(TNF-α),were determined using ELISA.Pathological changes in renal tissue were evaluated through hema-toxylin-eosin(HE)staining,while ultrastructural alterations were examined using transmission electron microscopy.Im-munohistochemistry and Western blotting were employed to assess STING protein expression in renal tissue,and STING mRNA expression was quantified via RT-qPCR.RESULTS:Compared to the normal group,the model group exhibited significant increases in BUN,ALB,and SCr levels(P<0.01),alongside elevated inflammatory markers IL-1β,IL-6,and TNF-α(P<0.01).Notable pathological changes included leukocyte wall thickening in capillaries,inflammatory cell infiltration,increased mesangial matrix,disorganized and linear alignment of podocytes,and thickening of the basement membrane.Moreover,STING protein and mRNA expression levels were significantly elevated(P<0.01).In contrast,the sinomenine hydrochloride group demonstrated significantly reduced levels of renal function markers(BUN,ALB and SCr)compared to the model group(P<0.01),as well as decreased concentrations of inflammatory factors IL-1β,IL-6,and TNF-α(P<0.01).Improvements in renal histopathology included decreased leukocyte wall thickening,reduced inflam-matory cell presence,diminished mesangial matrix,and a significant reduction in foot process fusion,alongside thinner basement membranes.Both STING protein and mRNA expression levels were also significantly lower(P<0.01).CON-CLUSION:Sinomenine hydrochloride effectively mitigates renal tissue injury,improves ultrastructural alterations,and inhibits inflammatory responses in db/db mice.Its mechanism of action appears closely linked to the downregulation of STING protein and mRNA expression.
