The occurrence of diabetes mellitus （DM） is closely related to insulin resistance and islet β cell dysfunction. Modern studies have found that macrophages are widely present in the liver，fat，skeletal muscle，islets， and other tissues and organs. Macrophage M1/M2 polarization plays an important role in the occurrence and development of diabetes mellitus and its related complications by intervening in inflammatory response，improving insulin resistance，and promoting tissue repair. Most of the traditional Chinese medicines that regulate the activation and polarization of macrophages are Qi-replenishing and Yin-nourishing，heat-clearing， and detoxicating medicinal，which are consistent with the etiology and pathogenesis of diabetes and its related complications. Therefore，by summarizing the mechanisms between macrophage activation，polarization， and insulin resistance in various tissues，this paper reviewed traditional Chinese medicine and its effective components and compounds in improving diabetes mellitus and its related complications through multi-channel regulation of macrophage polarization and regulation of M1/M2 ratio，providing references for the future treatment of DM and its related complications with traditional Chinese medicine.

Objective: To explore the clinical features, treatment and prognosis of emphysematous pyelonephritis (EPN), so as to enhance the clinical awareness of this disease. Methods: A retrospective analysis was conducted on the clinical data of one EPN patient at The Second Affiliated Hospital, Guangzhou University of Chinese Medicine, and a literature review was performed on articles published in the China National Knowledge Infrastructure and PubMed databases from Jan.1, 2015 to Dec.31, 2024. Results: The patient, a 62-year-old male with a 5 years' history of type 2 diabetes, was admitted due to left flank pain for 4 days, with a temperature of 39.4 ℃.Laboratory tests indicated significantly elevated inflammatory markers, decreased platelet count, and abnormal coagulation function.Preoperative blood and urine cultures showed positivity for Escherichia coli.Computed tomography (CT) revealed complete erosion of the left kidney, with gas in the left ureter and surrounding effusion, as well as multiple free gas in the abdominal cavity, bilateral ureteral stones, right renal lower calyx stones.After a multidisciplinary consultation, he underwent emergency phase Ⅰ left pyeloplasty and perirenal drainage with ureteral stenting.After discharge, the patient received maintenance hemodialysis once every two days in the outpatient clinic.One week after-discharge, the patient was readmitted due to polypnea.Following symptomatic management, vital signs stabilized.Approximately 2 months after the first-stage surgery, ureteroscopic stone extraction was successfully performed.One month after the stone extraction procedure, a follow-up CT showed normalization of the left kidney, renal pelvis and calyces, leading to phase Ⅱ laparoscopic left nephrectomy via the abdominal approach, with postoperative pathology indicating renal necrosis.Among 89 EPN patients reported in 35 articles, the median age was 58(24-92) years old；there were 59（66.3%） females and 30（33.7%） males；fever was the most common clinical symptom (60.7%)；73(82.0%) had diabetes, 12 (13.5%) had urinary tract obstruction；55 (61.8%) were infected with Escherichia coli, and 7 (7.9%) were infected with Klebsiella pneumoniae; 13 died due to ineffective treatmen. Conclusion: EPN presents acutely and progresses rapidly, often leading to misdiagnosis due to the lack of specific early symptoms.Abdominal CT is the preferred imaging modality for rapid diagnosis, and proactive interdisciplinary intervention can improve survival rates, reduce the need for nephrectomy, and enhance prognosis.

OBJECTIVE To evaluate the efficacy and safety of high-dose ilaprazole combined with amoxicillin for newly diagnosed elderly patients with Helicobacter pylori （Hp） infection， and analyze independent risk factors for failure of Hp infection eradication treatment. METHODS Totally 200 cases of newly diagnosed elderly patients with Hp infection in Xinxiang Central Hospital from August 1， 2021 to December 1， 2024 were selected and randomly divided into control group and study group， with 100 cases in each group. The control group was treated with classic quadruple therapy regimen （Amoxicillin capsules+ Clarithromycin tablets+Bismuth potassium citrate tablets+Ilaprazole enteric-coated tablets）. The study group was treated with high- dose Ilaprazole enteric-coated tablets+Amoxicillin capsules. All patients were administered medication for 2 weeks. Hp eradication rates in the two groups were compared using intention-to-treat （ITT） and per-protocol （PP） analyses. The incidence of adverse reactions in both groups was also recorded. The multiple-factor Logistic regression analysis was used to identify independent risk factors for failure of Hp infection eradication treatment. RESULTS In ITT and PP analyses， there was no significant difference of Hp eradication rates between the two groups （P＞0.05）. There was no significant difference in incidence of mild to moderate adverse reactions between the two groups （P＞0.05）. BMI ≤18.5 kg/m2， BMI ＞23.9 kg/m2， rural residence， concomitant diabetes and concomitant heart disease were identified as independent risk factors influencing the failure of Hp infection eradication treatment （P＜0.05）. CONCLUSIONS The efficacy and safety of high-dose ilaprazole combined with amoxicillin are comparable to classic quadruple therapy regimen in treating newly diagnosed elderly patients with Hp infection. Independent risk factors influencing the failure of Hp infection eradication treatment include BMI ≤18.5 kg/m2， BMI ＞23.9 kg/m2， rural residence， concomitant diabetes and concomitant heart disease.

Objective To compare H_p(3) calibration with a homemade (A) thermoluminescent dosimeter (TLD) and an imported (B) TLD in a standard X-ray RQR radiation field, to explore the different responses of A and B, and to provide foundation for the calibration of H_p(3). Methods A column mode was selected. H_p(3) calibration was performed using A and B in a standard X-ray RQR radiation field in the Secondary Standard Dosimetry Laboratory, National Institute for Radiological Protection, China Center for Disease Control and Prevention. Angle response, energy response, and linear response were calibrated with RQR4 (60 kV), RQR7 (90 kV), and RQR9 (120 kV), respectively. Results In terms of angle response, the calibration results of A were relatively high, while the calibration results of B were relatively low. In terms of energy response, the calibration results showed a similar pattern to angle response. In terms of linear response, the calibration results of both A and B were satisfactory. Conclusion Both A and B can be used for normal calibration of H_p(3) in a standard X-ray RQR radiation field. However, in actual monitoring, attention should be paid to the energy and angle response values of TLDs.

【Objective】 To analyze the correlation of HBV serological characteristics between non-reproducible reactivity (NRR) samples and occult hepatitis B virus infection (OBI) samples for blood screening. 【Methods】 A total of 144 samples with negative ELISA (HBV, HCV and HIV test) results and reactive nucleic acid tests(NAT) were collected from January 2021 to January 2023 in Anhui Blood Center, including 92 reactive samples by TMA method (combined ID-NAT) and 52 HBV DNA reactive samples by PCR method (ID-NAT). Supplementary differential testing and ID-NAT by PCR were performed on the reactive samples of the combined ID-NAT, samples that were non-reactive by both differential testing and ID-NAT by PCR were included in the NRR group, and samples that were reactive for HBV DNA detected by either method were included in the OBI group. Supplemented with HBsAg, anti-HBs, HBeAg, anti-HBe and anti-HBc tests, the differences in serological pattern and positive rate between NRR samples and OBI samples were analyzed. 【Results】 A total of 53 samples were negative for differential testing and ID-NAT and were included in the NRR group, 91 samples were detected as HBV DNA reactive in either method and were included in the OBI group. HBsAg and HBeAg were not detected by serological testing in either group. The detection rates of anti-HBs, anti-HBc and anti-HBe in the NRR group and the OBI group were 64.15% vs 47.25%, 86.79% vs 94.51%, 35.85% vs 52.75%, respectively. Comparison of serological patterns between the two groups: the most frequent pattern in the NRR group was anti-HBs (+ ) and anti-HBc (+ ) (32.08%), and the most frequent pattern in the OBI group was anti-HBe (+ ) and anti-HBc (+ ) (37.36%). 【Conclusion】 There were differences in some of the test results between the NRR samples and the OBI samples in HBV serological testing, and higher anti-HBc positive rate in the NRR samples suggests a higher possibility of HBV infection.

BACKGROUND:In recent years,the treatment of anterior cruciate ligament injury has become more and more mature.However,there are still disputes about the timing of surgery,the choice of surgical methods,the choice of grafts,and the methods to promote graft healing after anterior cruciate ligament injury. OBJECTIVE:To summarize the latest research progress of surgical timing,surgical methods,graft selection and methods to promote graft healing after anterior cruciate ligament injury,and to find new treatment directions for anterior cruciate ligament injury. METHODS:Relevant articles concerning anterior cruciate ligament injury were retrieved from PubMed,CNKI,WanFang Date,VIP,SinoMed,ScienceDirect,Springer and Cochrane Library.After the screening,72 related articles were finally included. RESULTS AND CONCLUSION:(1)Surgical timing:Compared with delayed anterior cruciate ligament reconstruction,early reconstruction can reduce meniscus injury,elevate quality of life,and improve functional recovery.However,it is still uncertain whether the different operation timing will accelerate cartilage injury.(2)Surgical methods:Arthroscopic anterior cruciate ligament reconstruction is a common surgical method for anterior cruciate ligament injury.Dynamic internal stabilization repair of anterior cruciate ligament can bring similar results to traditional anterior cruciate ligament reconstruction in short-term and long-term effects.(3)Graft selection:Autogenous hamstring tendon is the first choice of anterior cruciate ligament graft,while bone-patellar tendon-bone grafts and allografts are the secondary choices.(4)Among the methods to promote graft healing,suture band strengthening can increase knee joint stability and ensure graft healing.Stem cells promote the tendon-bone healing of grafts through anti-inflammatory action,angiogenesis,inhibition of osteolysis and promotion of chondrocyte differentiation.Preserving the residual end of the anterior cruciate ligament can maintain the stability of the knee joint,promote the recovery of proprioception,and provide a prerequisite for the healing of the graft.The effectiveness of platelet-rich plasma in promoting graft healing remains to be discussed.However,biomaterials,gene therapy,stem cell application and other methods to promote tendon healing remain in the stage of molecular and animal researches.Clinical transformation is also needed in the future.

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.

OBJECTIVE To study the correlation between penetration enhancement effect and transepidermal water loss(TEWL)values of essential oils(EOs)from traditional Chinese medicine(TCM).METHODS The amount of 3 kinds of glycosides(geniposide,gentiopicroside,paeoniflorin)and their oil-water partition coefficient were determined by HPLC.The penetration enhancement effect of the five EOs from Gaoliangjiang(Alpiniae Officinarum Rhizoma,AOR),Ganjiang(Zingiberis Rhizoma,ZR),Bohe(Menthae Haploca-lycis Herba,MHH),Hujiao(Piperis Fructus,PF)and Wuzhuyu(Euodiae Fructus,EF)on geniposide,gentiopicroside,and paeoniflor-in were performed by the modified Franz diffusion cell method with the abdominal skin of rats.The TEWL values were measured to evalu-ate the effect of the five EOs on the skin barrier function of rats.The correlation between penetration enhancement effect of EOs and their effect on skin barrier function was investigated by correlation analysis.RESULTS AOR oil,ZR oil,MHH oil,and PF oil could im-prove the absorption of the three glycosides and reduce skin barrier function of rats.The results of correlation analysis showed that the penetration enhancement effect of EOs was significantly related to TEWL values following dermal administration of EOs.CONCLUSION TEWL measurement technology provides a more convenient method for the selection of penetration enhancers.

Objective:This study aimed to assess the effects of Peer Balint-style group on the empathy ability of third-year long-term medical students and to provide a theoretical and practical reference for effectively improving their humanistic quality.Methods:Ninety third-year Chinese long-term medicine students participated. Volunteers received either ten sessions of 1.5-h Peer Balint-style group which were led by specially trained peers from June 2019 to August 2019. The College Students' Empathy Ability Questionnaire was used before the experiment and the second day after the experiment. The total score of the scale from the pre-test and post-test and the scores of each dimension conformed to a normal distribution, with equal variance, describing in the form of ( x± s). Paired t-tests were performed to compare the total score and each dimension score before and after the intervention, using SPSS 22.0. Semi-structured interviews were conducted with 7 peer-group leaders and group members after the clinical practice period. The interview materials were analyzed by traditional content analysis. The content of the qualitative research was open-coded to obtain 10 categories, suggesting the role and inadequacy of Peer Balint-style groups. Results:A total of 63 valid samples were obtained. There was no significant difference of ( t=-0.44, P=0.661, P>0.05) between the total score of the post-test (118.00±11.98) and the total score of the pre-test (117.38±12.36). In each dimension, the reverse comprehension score of post-test (9.06±1.97) was significantly different ( t=-2.08, P=0.041, P>0.05) from the pre-test's (8.57±2.15), which increased compared to the pre-test score. Conclusions:Peer Balint-style group had a positive effect on improving empathy among medical students. Compared with the traditional Balint group, it has wider coverage, higher affinity and greater mobility. However, the design of the Peer Balint-style group still needs to be further improved.
