ABSTRACT
Objective To evaluate the efficacy of surgery,chemotherapy and surgery combined chemotherapy for retinoblastoma(RB),and analyze the prognostic factors of RB patients.Methods Clinical data of 1188 RB patients registered in the Surveillance,Epidemiology and End Results(SEER)database from January 2000 to December 2019 were retrospectively analyzed.The baseline characteristics of patients treated with surgery,chemotherapy or surgery combined with chemotherapy were balanced by inverse probability of treatment weighting(IPTW).Log-rank test analysis was used to compare the survival probability of patients in the 3 groups,and Cox regression models were used to analyse the factors influencing the prognosis of RB patients.Results A total of 1188 RB cases were included in this study,including 426 cases in surgery group,200 cases in chemotherapy group and 562 cases in surgery combined with chemotherapy group.After IPTW weighting,baseline data such as age,sex and race were balanced(P＞0.05).Log-rank test results showed that the survival curves of the three groups were significantly different before and after weighting(P＜0.05).After weighted,the survival of patients in surgery group was significantly better than that in chemotherapy group and surgery combined chemotherapy group(P＜0.05),and there was no statistical significance between chemotherapy group and surgery combined chemotherapy group(P＞0.05).The weighted patient survival probability at 1st,3rd and 5th years were 99.7%,98.9%and 98.6%in surgery group;97.4%,95.8%and 95.8%in chemotherapy group;and 97.9%,95.8%and 95.0%in surgery combined chemotherapy group.Cox regression analysis showed that compared with surgery group,the specific risk ratio of death was 1.367(95%CI 1.100-1.700)in chemotherapy group and 1.132(95%CI 0.963-1.330)in combined chemotherapy group.Compared with patients with 1 RB lesion,the patient-specific mortality risk ratio for patients with 2 or more RB lesions was 0.399(95%CI 0.268-0.594).Conclusions Patients with RB have higher survival rates probability after treatment.After controlling the influence of age,sex and other factors,the effect of surgery was better among the three treatment methods.Multifocality may be an independent prognostic factor in RB patients.
ABSTRACT
Objective To explore the manufacturing process and performance of laser-cut 316L medical catheters based on catheter designs with different cutting methods.Methods Two design schemes of straight and oblique spiral cut were proposed under interrupted spiral cut pattern.Straight and oblique spiral cut medical catheters were obtained with desired laser parameters,cutting speed and focus position of the laser cutting machine,oxygen as the auxiliary gas and nitric acid and hydrofluoric acid as the acid cleaning solution for the post-treatment process,which were compared with Direxion torqueable microcatheter and tested for traceability,torsion control and tensile strength.Results Laser-cut 316L medical catheters were less likely to hurt blood vessels for its advantages over Direxion torqueable microcatheter in surface brightness and roundness of grooved edges,while Direxion torqueable microcatheter behaved better in intensity and width uniformity of grooves and regularity of semi circles at ends of grooves.Straight spiral cut medical catheters had the traceability,torsion control and tensile strength increased by 50％,22％and 33％respectively when compared with oblique spiral cut catheters.Conclusion Laser cutting parameters and post-treatment process are the main factors affecting the appearance and size of laser cut medical catheters,and also of importance for improving the qualified rate of product processing and assembly.The catheter cutting design scheme is also a key element influencing the physical properties of medical catheters.[Chinese Medical Equipment Journal,2024,45(1):31-36]
ABSTRACT
Objective To investigate the effects of long noncoding RNA(lncRNA)-NRON on apoptosis following myocardial infarc-tion(MI)in mice.Methods The C57BL/6 mice were randomly divided into four groups:sham operation(Sham)group,MI group,MI combined with lncRNA-NRON interference lentivirus(MI+shNRON)group,and MI combined with the negative control(NC)lentivirus(MI+NC)group.The expression of lncRNA-NRON was detected using real-time PCR.In addition,the pathology of the myocardial tissue injury was analyzed using HE staining,the myocardial infarction size was examined using TTC staining,and the extent of apoptosis was assessed using the TUNEL assay,respectively.The RPISeq database was used to predict the probability of interaction between lncR-NA-NRON and the voltage-dependent anionic channel protein(VDAC).The effect of lncRNA-NRON on the expression of VDAC protein was detected using Western blotting.Results The lncRNA-NRON expression was significantly increased in the MI group,and the tar-geted knockdown of lncRNA-NRON resulted in alleviation of the pathological myocardial tissue injury,reduction in the myocardial infarc-tion area,and inhibition of apoptosis.The probability of interaction between lncRNA-NRON and VDAC reached 0.9,indicating a high probability of their association.Additionally,lncRNA-NRON could regulate the protein expression of VDAC.Conclusion Knockdown of lncRNA-NRON could reduce the occurrence of myocardial injury following myocardial infarction.This effect may be attributable to a spe-cific mechanism wherein lncRNA-NRON affects the process of apoptosis by binding to VDAC,consequently suppressing its expression.
ABSTRACT
Objective:To investigate the clinical effect of high diffusion sensitivity coefficient(high b value)diffusion-weighted imaging(DWI),dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI)combined with tumor carbohydrate antigen 125(CA125)in judging the nature of ovarian lesions.Methods:A total of 100 patients with ovarian lesions who were treated in Nantong Haimen People's Hospital from April 2020 to April 2022 were selected for retrospective study.All of them underwent CA125,DWI,DCE-MRI and pathologically qualitative examination.According to the pathological results,58 patients with malignant lesions of ovarian were divided into malignant group and patients with benign lesions of ovarian were divided into benign group.The CA125 levels of the two groups were analyzed and compared,and the results of the receiver operating characteristics(ROC)of different detection methods(DWI with high b value+CA125,DCE-MRI+CA125,DWI with high b value+DCE-MRI+CA125)also were analyzed and compared.Results:The CA125 index of the malignant group was significantly higher than that of the benign group,with a statistically significant difference(t=29.357,P＜0.05),and the CA125 positive rate of the malignant group was significantly better than that of the benign group,with a statistically significant difference(x2=34.456,P＜0.05).The apparent diffusion coefficient(ADC)value[(0.91±0.18)×103mm2/s]of the malignant group was significantly less than that[(33±0.21)×103mm2/s]of the benign group,while the contrast agent volume conversion constant(Ktrans),rate constant(Kep)and the extracellular space volume ratio outside of blood vessels(Ve)of the malignant group were significantly higher than those of the benign group,with significant differences(t=16.863,9.686,10.205,P＜0.05),respectively.The diagnostic accuracy,sensitivity,negative predictive value and positive predictive value of DWI with high b-value+DCE-MRI+CA125 examination method were higher than those of DWI with high b-value + CA125 or DCE-MRI+CA125 examination method in diagnosing malignant ovarian tumors.There were not significant differences in various indicators between DCE-MRI+CA125 examination method and DWI with high b-value +CA125 examination method(P＞0.05).ROC curve analysis showed that the area under curve(AUC)of the DWI with high b-value +DCE-MRI+CA125 examination method was the best(AUC=0.920).Conclusion:The combined examination method of DWI with high b-value + DCE-MRI + CA125 has better overall diagnostic efficiency,which can improve the screening ability of clinical diagnosis for malignant ovarian tumors.It has a certain clinical application value.
ABSTRACT
Objective:To construct the impact factor model of primary traditional Chinese medicine (TCM) health management service quality, and put forward corresponding policy suggestions.Methods:In this cross-sectional study, the typical sampling and random sampling method were used to select 39 insiders of primary TCM health management service from 15 communities in Zhejiang Province from August to October in 2022. Interviews on service projects, implementation effects and impact factors were conducted, the three-level coding of interview record was carried out using the grounded theory research method, a model of impact factor for health management service quality of basic TCM was constructed, and the corresponding policy recommendations were put forward.Results:Based on the open coding of 39 original interview data, a total of 516 reference points were obtained, and 53 initial concepts related to the topic were formed and summarized into 17 first-level categories. Through the summary of main axis coding, 6 main categories of “policy environment”，“health literacy”，“community orientation”，“capacity building”，“health preference” and “conflict of interest” were extracted. The logical correlation between the six main categories were analyzed with selective coding, an impact factor model was constructed in accordance with the story line of factors affecting service quality. The story line of this model was as follows: first, the policy environment was the external guarantee of community TCM service quality; second, as the demand-side of the services, the health literacy and requirement of residents was the regulatory factor for service quality; in addition, the community played the role of the supply-side of the services, the service ability construction was the key factor, and the community functions and target orientation was the internal driving factor, meanwhile, the internal/external conflicts of interest had a negative constraint on the service quality.Conclusions:The guarantee intensity of external policy environment is limited, the service demand side pays insufficient attention, and the service supply side functions are absent at the present stage. It is necessary to improve the external policy environment, deepen the connection between supply and demand sides in the field of TCM health service, promote the capacity building of TCM service at the grass-roots level, balance the interests of relevant departments of TCM service, in order to improve the quality of TCM health management service at the grass-roots level.
ABSTRACT
The theory of "linkage between spleen and small intestine" has been put forward by doctors as early as the Ming dynasty. In traditional Chinese medicine， the spleen and small intestine cooperate and work together physiologically， and they are also closely related and interact with each other pathologically. The spleen governs transportation and transformation， which involves the function of the small intestine in transforming water and grain. The small intestine， governing the receiving and transformation of substances， depends on the normal transportation of the spleen. At the same time， it provides guarantee for the spleen to transform Qi and generate blood as well as ascend lucidity and descend turbidity. The dysfunction of spleen in transportation is closely related to the dysfunction of small intestine. The stability of intestinal microecology necessitates the normal functioning of the spleen. When the original balance of intestinal flora is disturbed， the spleen functioning will be affected. This study explored the pathogenesis and treatment of diabetes based on the physiological functions of the spleen and small intestine and the Western medicine targets of "nutrients-intestinal flora". According to modern medicine， nutrients are essential to maintain the normal physiological activities of the human body. Proper intake of nutrients can affect the absorption and metabolism of the human body for nutrients by regulating the composition and function of intestinal flora， so as to prevent the occurrence of diabetes. The imbalance of intestinal flora which harbors rich microorganisms may lead to the disturbance of energy metabolism and the dysfunction of the immune system， eventually leading to diabetes. As a metabolic disease， diabetes is closely related to the imbalance of intestinal flora and nutrient intake. Based on the theory of "linkage between spleen and small intestine"， this paper discusses the relationship between spleen and small intestine. Furthermore， this paper discusses the correlation between "spleen-small intestine" and "nutrients-intestinal flora" by reviewing the latest progress in modern medicine and clinical research， aiming to provide a theoretical basis and new ideas for the clinical prevention and treatment of type 2 diabetes mellitus.
ABSTRACT
ObjectiveTo explore the underlying mechanism by which the Chinese medicine compound Yitangkang granule（YTK） treats diabetic kidney disease （DKD） by observing its effects on podocyte autophagy through the regulation of phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）/forkhead transcription factor O1 （FoxO1） signaling pathway mediated by silent information regulator 1 （SIRT1） via advanced glycation end products （AGE）/receptor for AGE （RAGE） axis. MethodNinety-six 8-week-old healthy male SPF-grade Wistar rats were selected and randomly divided into blank control group （B）， model control group， high-dose YTK （40 g·kg-1）， medium-dose YTK （20 g·kg-1）， low-dose YTK （10 g·kg-1）， and Western medicine control （20 mg·kg-1 losartan） groups. The DKD rat model was established by high-fat diet feeding combined with intraperitoneal injection of streptozotocin. After successful modeling， the rats in each group received the corresponding treatments for eight weeks. The levels of superoxide dismutase （SOD）， malondialdehyde （MDA）， glutathione peroxidase （GSH-Px）， and catalase （CAT） were measured according to the instructions of the respective assay kits. Hematoxylin and eosin （HE） staining was used to observe pathological changes in kidney tissues. Immunohistochemistry was employed to detect the average optical density values of α-smooth muscle actin （α-SMA）， fibronectin （FN）， desmin， and nephrin. Western blot analysis was used to measure the expression levels of PI3K， phosphorylated PI3K （p-PI3K）， Akt， phosphorylated Akt （p-Akt）， RAGE， SIRT1， Caspase-3， and FoxO1 proteins in kidney tissues of DKD rats. ResultCompared with the blank control group， the model group showed significantly lower levels of SOD， GSH-Px， and CAT， and significantly higher levels of MDA （P<0.01）. The rats exhibited severe kidney damage. The positive expression of podocyte marker proteins α-SMA， FN， and desmin increased significantly， while nephrin and podocin significantly decreased （P<0.01）. The expression levels of PI3K， p-PI3K， Akt， p-Akt， RAGE， and Caspase-3 proteins were significantly elevated， while SIRT1 and FoxO1 protein levels were significantly reduced （P<0.01）. Compared with the model control group， rats in the YTK treatment groups showed significantly higher levels of SOD， GSH-Px， and CAT， and significantly lower levels of MDA in serum （P<0.01）. The degree of kidney damage was reduced to varying extents. The average optical density values of podocyte marker proteins α-SMA， FN， and desmin were significantly decreased， while nephrin and podocin significantly increased （P<0.01）. The expression levels of PI3K， p-PI3K， Akt， p-Akt， RAGE， and Caspase-3 in kidney tissues were significantly reduced， while SIRT1 and FoxO1 expression levels significantly increased （P<0.01）. The Chinese medicine groups demonstrated a clear dose-response trend. ConclusionYTK may alleviate kidney pathological damage， reduce proteinuria， and protect kidney function in DKD rats， thereby delaying the progression of DKD by improving podocyte autophagy through the AGE-RAGE axis-mediated SIRT1 regulation of the PI3K/Akt/FoxO1 signaling pathway. Additionally， a dose-response relationship was observed in the Chinese medicine groups.
ABSTRACT
Objective:To develop a grading system for necrosis of pedicled flaps in reconstruction of foot and ankle, and to verify its effectiveness and repeatability.Methods:A retrospective observational study was conducted. A total of 40 necroses of foot and ankle pedicled flaps were selected by 2 senior surgeons based on the flap surgery performed by the same surgical group in Department of Orthopaedic Surgery, the 920 Hospital of Joint Logistic Support Force of PLA from January 2010 to January 2022. A grading system for pedicled flap necrosis was proposed by a working group and the 40 necrotic flaps were graded. The coincidence rate was calculated to evaluate the effectiveness of the grading system through correlation studies between grading and clinical treatment. One photo of a typical postoperative necrotic flap was collected from each of the 40 flaps. Then 5 extramural surgeons were asked to grade the necroses shown on the photos according to the proposed grading system. Moreover, weighted Kappa analysis was performed on the results of proposed grading system and also on the standard grading currently in use, to evaluate the repeatability of the proposed grading system. Evaluated data were expressed by Mean±SD, and the coincidence rate was expressed by percentage. The reproducibility was studied by weighted Kappa analysis.Results:Of the 40 necrotic flaps, 7 flaps were classified in Grade I, 16 in Grade Ⅱ, 12 in Grade Ⅲ and 5 in Grade IV. In comparison with the actual treatment methods, the overall coincidence rate of the grading system was 92.5%. It indicated that the proposed grading system could effectively guide the selection of a treatment procedure. The average weighted Kappa coefficient of surgeons was at 0.628 with a 95% confidence interval (95%CI) between 0.460-0.796, which was strongly consistent with the standard of the grading system currently in use.Conclusion:The grading system for necrosis of pedicled flap in reconstruction of foot and ankle proposed in this study is simple and clear. It is able to effectively guide the treatment of flap necrosis. The preliminary validation shows that the classification system has good repeatability.

Old age， overweight and obesity， central obesity， smoking， drinking， farmers， unmarried， and low family income were the risk factors of CVD， while high education level was the protective factor. In the participants， 16 323 people （81.34%） were classified as CVD high-risk groups； The number of aggregation of 1， 2 and ≥3 high risk types of CVD were 16 323（81.34%）， 3 236（16.13%）， 509（2.54%）， respectively. Old age， low education level， low annual family income， farmers， unmarried， smoking， drinking， overweight， obesity and central obesity were associated with the risk of aggregation of high risk types of CVD， and the correlation strength increased with the increase of aggregation types. ConclusionThe prevention and control of CVD in Shanghai should focus on the hypertension， elderly， overweight， obesity， central obesity， smoking， drinking， low educated， low family income， farmers and unmarried people， and targeted intervention measures should be taken to reduce the risk of CVD among residents.
ABSTRACT
Objective: To analyze the clinical characteristics and prognosis of patients with infant acute lymphoblastic leukemia (IALL). Methods: A retrospective cohort study.Clinical data, treatment and prognosis of 28 cases of IALL who have been treated at Beijing Children's Hospital, Capital Medical University and Baoding Children's Hospital from October 2013 to May 2023 were analyzed retrospectively. Based on the results of fluorescence in situ hybridization (FISH), all patients were divided into KMT2A gene rearrangement (KMT2A-R) positive group and KMT2A-R negative group. The prognosis of two groups were compared. Kaplan-Meier method and Log-Rank test were used to analyze the survival of the patients. Results: Among 28 cases of IALL, there were 10 males and 18 females, with the onset age of 10.9 (9.4,11.8) months. In terms of immune classification, 25 cases were B-ALL (89%), while the remaining 3 cases were T-ALL (11%). Most infant B-ALL showed pro-B lymphocyte phenotype (16/25,64%). A total of 22 cases (79%) obtained chromosome karyotype results, of which 7 were normal karyotypes, no complex karyotypes and 15 were abnormal karyotypes were found. Among abnormal karyotypes, there were 4 cases of t (9; 11), 2 cases of t (4; 11), 2 cases of t (11; 19), 1 case of t (1; 11) and 6 cases of other abnormal karyotypes. A total of 19 cases (68%) were positive for KMT2A-R detected by FISH. The KMT2A fusion gene was detected by real-time PCR in 16 cases (57%). A total of 24 patients completed standardized induction chemotherapy and were able to undergo efficacy evaluation, 23 cases (96%) achieved complete remission through induction chemotherapy, 4 cases (17%) died of relapse. The 5-year event free survival rate (EFS) was (46±13)%, and the 5-year overall survival rate (OS) was (73±10)%.The survival time was 31.3 (3.3, 62.5) months. There was no significant statistical difference in 5-year EFS ((46±14)% vs. (61±18)%) and 5-year OS ((64±13)% vs. (86±13)%) between the KMT2A-R positive group (15 cases) and the KMT2A-R negative group (9 cases) (χ2=1.88, 1.47, P=0.170, 0.224). Conclusions: Most IALL patients were accompanied by KMT2A-R. They had poor tolerance to traditional chemotherapy, the relapse rate during treatment was high and the prognosis was poor.

Background Multiple studies have shown a close relationship between changes in gut microbiota composition and obesity, and research results are influenced by factors such as race and geographical location, but there are few studies on children. Objective To analyze the diversity of gut microbiota related to obesity in a population of 2-6 years old, observe the distribution characteristics and species differences of gut microbiota between obese/overweight and normal weight groups, and explore the association betweenobese/overweight and gut microbiota diversity. Methods Fecal samples were collected from 74 children aged 2-6 years in Shanghai, including 18 obese/overweight individuals, 6 males and 12 females (male to female ratio of 1∶2), and 56 normal weight individuals, 18 males and 38 females (male to female ratio is nearly 1∶2). The 16S rDNA was extracted from bacteria in fecal samples, followed by PCR amplification, cDNA construction, and high-throughput sequencing. Naive Bayes algorithm was used to perform taxonomic analysis (phylum, class, order, family, genus, species) and community diversity analysis (Sobs index, Shannon index, Shannoneven index, Coverage index, PD index, and principal co-ordinates analysis) on representative sequences and abundance of amplicon sequence variants (ASV). Wilcoxon rank sum test, P-value multiple test correction, and analysis of similarities were used to test differences between the two groups to obtain information on the distribution characteristics and species differences of intestinal microbiota in children. Results Seventy-four fecal samples were sequenced, and the sequencing results were subjected to quality control and filtering. A total of 4905306 optimized sequences were obtained, resulting in 1860 ASVs. The diversity data analysis of ASVs generated 889 species annotation results at 8 taxonomic levels. The alpha diversity analysis showed that the richness (Sobs index), diversity (Shannon index), evenness (Shannoneven index), and phylogenetic diversity (PD index) of fecal community of the obese/overweight children were increased compared to those of the normal weight children, but there were no statistical differences between the two groups (P>0.05). The beta diversity analysis showed that there was little difference in the composition of microbial species between the two groups, and no significant clustering separation was observed. The results of species composition analysis at phylum, order, family, and genus levels of 74 samples showed a consistent core microbiota structure in the two groups of gut microbiota, but there were differences in microbiota composition. The differences in microbial community composition between the two groups were manifested at the taxonomic levels of order, family, and genus, among which phylum Firmicutes, order Erysipelotrichales, family Erysipelatocyclostridiaceae, genus Erysipelotrichaceae_ UCG-003 and genus Catenibacterium were significantly enriched in the obese/overweight group and contributed significantly to the phenotypic difference of obese/overweight [linear discriminant analysis (LDA)=3.72, P<0.01; LDA=3.29, P<0.05). Phylum Proteobacteria, order Enterobacterales, family Enterobacteriaceae, genus unclassified was significantly enriched in the normal weight group and contributed significantly to the phenotypic difference of normal body weight (LDA=3.93, P<0.05). Conclusion The richness and diversity of gut microbiota in obese/overweight children aged 2-6 years in Shanghai are increased, but there is no difference compared to normal weight children. There is a difference in the composition of gut microbiota between the obese/overweight group and the normal weight group.

To provide proof of the evidence-based medicine and decision-making information for the clinical decision of functional gastrointestinal disorders(FGIDs), this study evaluated and compared the efficacy, safety, and economy of four oral Chinese patent medicines(CPMs) in the treatment of FGIDs using the method of rapid health technology assessment. The literature was systematically retrieved from CNKI, Wanfang, VIP, SinoMed, EMbase, PubMed, Cochrane Library and ClinicalTrials.gov from the establishment of the databases to May 1, 2022. Two evaluators screened out the literature, extracted data, evaluated the quality of the literature, and descriptively analyzed the results according to the prepared standard. Eventually, 16 studies were included, all of which was rando-mized controlled trial(RCT). The results showed that Renshen Jianpi Tablets, Renshen Jianpi Pills, Shenling Baizhu Granules, and Buzhong Yiqi Granules all had certain effects on the treatment of FGIDs. Renshen Jianpi Tablets treated FGIDs and persistent diarrhea. Shenling Baizhu Granules treated diarrhea with irritable bowel syndrome and FGIDs. Buzhong Yiqi Granules treated diarrhea with irritable bowel syndrome, FGIDs, and chronic diarrhea in children. Renshen Jianpi Pills treated chronic diarrhea. The four oral CPMs all have certain effects on the treatment of FGIDs and have specific advantages for specific patients. Compared with other CPMs, Renshen Jianpi Tablets have higher clinical universality. However, there are problems such as insufficient clinical research evidence, generally low quality of evidence, lack of comparative analysis among medicines, and lack of academic evaluation. More high-quality clinical research and the economic research should be carried out in the future, so as to provide more evidence for the evaluation of the four CPMs.

Objective To make a system evaluation regarding the effect and safety of the"Nourishing Kidney and Activating Blood"method in the treatment of diabetic cognitive impairment.Methods According to the requirements of evidence-based medicine,the domestic and foreign databases were searched comprehensively,and the time limit was from the establishment of databases to June 2022,so as to find out the clinical randomized controlled trials of"Nourishing Kidney and Activating Blood"method in treating diabetic cognitive impairment.Revman5.3 was used for meta-analysis and risk bias evaluation,TSA0.9 for sequential analysis,Stata15.0 for publication bias evaluation,and GRADE3.6 for evidence quality evaluation.Results Eventually,14 RCTs were included with a sample size of 1126 cases.Meta-analysis showed that compared with conventional western medicine treatment,the"Nourishing Kidney and Activating Blood"method could significantly improve the effective rate of treating cognitive dysfunction in diabetes[OR=5.06,95%CI(3.38,7.57),P<0.00001],and significantly improve the total MoCA score of patients[MD=2.11,95%CI(1.76,2.47),P<0.00001],MMSE score[MD=1.86,95%CI(1.13,2.59),P<0.00001],MQ score[MD=13.40,95%CI(11.23,15.57),P<0.00001]and HDS score[MD=-3.36,95%CI(2.61,4.11),P<0.00001].Meanwhile,the"Nourishing Kidney and Activating Blood"method could reduce the level of glycosylated hemoglobin in DCI patients[MD=-0.84,95%CI(-1.37,-0.32),P=0.002].However,since the drugs used in the control group have no hypoglycemic effect,this conclusion needs to be further verified.In addition,the ability of the"Nourishing Kidney and Activating Blood"method to improve CDR score[MD=-0.01,95%CI(-0.08,0.07),P=0.84],ADL score[MD=2.10,95%CI(-1.62,5.82),P=0.27],TCM syndrome score[MD=-4.46,95%CI(-10.94,2.02),P=0.18]and reduce adverse reactions[OR=0.36,95%CI(0.08,1.60),P=0.18]was equivalent to that of conventional western medicine.Begg's test and Egger's test suggested that there might be some publication bias in the research.Metaninf command chart and sequential analysis of experiments indicated that the stability of research results was relatively good.The quality evaluation of evidence showed that the evidence of effective rate,glycosylated hemoglobin,MoCA scale score,MMSE score and MQ score was medium quality,the evidence of fasting blood glucose,CDR score and HDS score was low quality,and the evidence of ADL score,TCM syndrome score and adverse reactions was extremely low quality.Conclusion The existing literature evidence showed that the"Nourishing Kidney and Activating Blood"method had a good clinical effect in treating diabetic cognitive impairment,and it could reduce the blood glucose level and improve the cognitive function of patients,with certain safety.However,the above conclusions still needed more large samples and multi-center RCT to be further verified due to the limitation of the quality and quantity of the included literature.
ABSTRACT
Objective:To investigate the efficacy of endoscopic retrograde cholangiopancreatography in the treatment of Child-Pugh C cirrhosis complicated by obstructive jaundice and its effects on liver function and infection indexes.Methods:The clinical data of 86 patients with Child-Pugh C cirrhosis complicated by obstructive jaundice who received treatment in the Affiliated Hangzhou Xixi Hospital, Zhejiang University School of Medicine, from June 2017 to June 2022 were retrospectively analyzed. These patients were divided into an observation group ( n = 56) and a control group ( n = 30) according to different treatment methods. Patients in the observation group underwent endoscopic retrograde cholangiopancreatography and those in the control group received conservative drug treatment. After 14 days of treatment, clinical efficacy was compared between the two groups. The changes in liver function [alanine aminotransferase (ALT), aspartate aminotransferase (AST), glutamyl transpeptide (GGT)] and infection indicators [white blood cell count (WBC), procalcitonin (PCT), and C-reactive protein (CRP)] were compared between the two groups before and after treatment. The incidence of postoperative complications was compared between the two groups. At 6 months after treatment, the prognosis was compared between the two groups. Results:The total response rate in the observation group was 98.21% (55/56), which was significantly higher than 60.00% (18/30) in the control group ( Z = 23.43, P < 0.001). Before treatment, serum ALT, AST, GGT levels in the control group were (294.53 ± 45.19) U/L, (286.62 ± 17.15) U/L, and (304.53 ± 12.34) U/L, respectively, and they were (96.25 ± 16.7) U/L, (113.25 ± 8.56) U/L, (122.25 ± 9.24) U/L after 14 days of treatment. Before treatment, serum ALT, AST, and GGT levels in the observation group were (352.36 ± 70.23) U/L, (303.31 ± 12.12) U/L, and (368.36 ± 10.23) U/L, respectively, and they were (108.65 ± 12.38) U/L, (95.65 ± 6.54) U/L, and (85.66 ± 7.28) U/L, respectively, after 14 days of treatment. After treatment, serum ALT, AST, and GGT levels in each group were significantly decreased compared with those before treatment (observation group t = 22.54, 49.54, 64.76; control group t = 25.57, 112.83, 168.48, all P < 0.05). After treatment, the amplitude of decrease in serum ALT, AST, and GGT levels in the observation group were significantly greater than those in the control group ( t = 2.27, 3.18, 4.61, all P < 0.05). After treatment, PCT, CRP, and WBC in each group were significantly decreased compared with those before treatment (observation group: t = 11.68, 11.46, 5.42, control group: t = 20.39, 18.69, 19.02, all P < 0.05). After treatment, the amplitude of decrease in serum PCT, CRP, and WBC in the observation group were significantly greater than those in the control group ( t = 5.14, 1.67, and 2.11, all P < 0.05). Within 14 days after treatment, there were two cases of acute pancreatitis, one case of hyperamylasemia, and one case of transient biliary bleeding in the observation group. There was one case of acute pancreatitis in the control group. The incidence of complications in the observation group was slightly, but not significantly, higher than that in the control group ( P > 0.05). After treatment, 12 patients (40.00%) in the control group experienced worsening jaundice, and additional endoscopic retrograde cholangiopancreatography salvage treatment was given. After treatment, total bilirubin level decreased by > 50%, reaching the standard of significant efficacy. At 6 months after treatment, stent obstruction occurred in two patients, which was effectively treated by replacement. There were no deaths in each group during the follow-up period. Conclusion:Implantation of a nasobiliary duct or a biliary duct stent during endoscopic retrograde cholangiopancreatography is more effective at treating yelloxemia in patients with Child-Pugh C cirrhosis complicated by obstructive jaundice than medication. The former method can effectively relieve obstructive jaundice, smooth drainage, improve liver function, reduce infection, and be relatively safe.
ABSTRACT
Objective:To investigate the clinical outcomes of Ortho-Bridge Combination System (OBCS) to achieve precise ulna-shortening osteotomy (USO) in the treatment of ulnar impaction syndrome.Methods:A retrospective study was conducted to analyze the 25 patients with ulnar impaction syndrome who had been treated at Institute of Orthopedic Trauma Research, The 920th Hospital of Joint Logistic Support Force of Chinese People's Liberation Army between January 2020 to March 2022. The patients all underwent USO using OBCS. They were 14 females and 11 males with an age of (43.2 ± 10.1) years. Their CT scans were retrieved for preoperative planning and design of a personalized USO. Intraoperatively, OBCS was fixated to the ulna before USO. After the bone was resected according to preoperative planning, the gap between the osteotomy sites was closed with compression, and OBCS was finally fixated with locking screws. The time for bone union after resection, complications, range of motion and grip strength were recorded. The clinical outcomes were evaluated by visual analogue scale (VAS) and Mayo wrist score.Results:All patients completed their operations successfully using OBCS. Their follow-up time was (13.5 ± 1.2) months. The ulnar variation was corrected and osteotomy ends got united in all patients, without nonunion, angulation, or rotation. The wrist VAS significantly decreased from 6.0 (5.0, 6.5) points before operation to 2.0 (1.0, 2.0) points at the last follow-up ( P<0.05). At the last follow-up, the Mayo wrist score [(85.4 ± 8.9) points], grip strength [(39.4 ± 1.2) kg], wrist flexion-extension (111.9° ± 12.6°), wrist pronation-supination (133.2° ± 15.7°), and ulnar radial deviation (35.3° ± 2.8°) were significantly increased compared with the preoperative values [(69.2 ± 13.3) points, (31.3 ± 5.2) kg, 102.0° ± 16.0°, 128.0° ± 15.5°, and 32.2° ± 2.8°] ( P<0.05). Conclusion:In the treatment of ulnar impaction syndrome, OBCS can facilitate the process of USO, correct ulnar variance, and avoid complications like rotation and angulation to improve functions of the wrist.
ABSTRACT
Ferroptosis is a novel iron-dependent mode of programmed cell death characterized by iron deposition and accumulation of lipid peroxidation. More and more studies have found that ferroptosis is closely related to the pathogenesis of type 2 diabetes mellitus （T2DM）. The yin-fire theory is an important part of LI Gao's spleen-stomach theory， and it is believed that qi-fire imblance and yin-fire internal generation is the main pathogenesis of T2DM. Abnormal iron metabolism may be an important prerequisite for T2DM yin-fire internal generation， while oxidative stress is the specific manifestation of T2DM qi-fire imbalance. Reactive oxygen species （ROS） is the end product of qi-fire imbalance， and lipid peroxide is the pathological products of T2DM yin-fire internal generation. This study intends to explore the pathological mechanism of qi-fire imbalance and yin-fire internal generation from the perspectives of iron metabolism， oxidative stress and lipid peroxidation， enriching the modern connotation of yin-fire theory， and benefiting traditional Chinese medicine to target against ferroptosis， and prevent and treat T2DM precisely.
ABSTRACT
Objective:To investigate the efficacy of digital reconstruction technology in assisted design of lobulated deep inferior epigastric perforator flap (DIEPF) for surgical reconstruction of large defect in lower extremity.Methods:From January 2017 to January 2022, a study was carried out to retrospectively analyse 8 patients who had massive soft tissue defects in lower extremities were admitted in the Department of Orthopaedic Surgery of the 920 Hospital of Joint Logistic Support Force of Chinese PLA. The size of defects varied from 16.0 cm×12.0 cm-28.0 cm×22.0 cm. CTA scans were performed over abdominal aorta and the arteries of lower extremities. Three-dimensional model of DIEPF and vascular pedicles were reconstructed by Mimics software. According to the shape and size of the wound, targeted perforators were determined on the 3D images, and precisely mapped in a digitised rectangular coordinate system. The lobulated flap was then digitally designed in the 3D coordinate system. Flaps were harvested according to preoperative digital designs for the reconstruction of large defects in the lower extremities. The donor site was sutured directly. The flaps and recovery of lower extremities were observed though postoperative follow-ups and were conducted through visits of outpatient clinics and distance interviews via telephone and WeChat. Recoveries of lower extremities were evaluated using Maryland ankle-foot function scoring system.Results:The 3D reconstructed models of the vessels in donor sites were successfully completed for all patients. The harvests of lobulated DIEPF were successfully guided by the digital designs. Fifteen lobes of lobulated DIEPF survived successfully in all 8 patients. All donor sites were closed in the stage-I. Necrosis occurred at the distal tip of a lobulated flap due to a local venous occlusion, and healed after debridement and re-suture. Four patients received further flap debulking surgery. Time of postoperative follow-ups had ranged 15-27 months, with an average of 20 months. At the last follow-up, all the flaps had satisfactory appearance with linear scars at the donor sites. All fractures were healed. Five patients achieved Maryland's ankle-foot function score in excellent, 2 in good, and 1 was acceptable.Conclusion:Digital reconstruction technology can accurately map the perforators and reasonably assist the design of lobulated flaps. A lobulated DIEPF offers a wider area for flap excision and allows a primary closure of the donor sites. Combination of the 2 advantages of a lobulated DIEPF can be effectively applied in reconstruction of a large-sized defect in lower extremity.
