Neuropathic pain is one of the common complications of diabetes. Tetrahydropalmatine(THP) is a main active component of Corydalis Rhizoma with excellent anti-inflammatory and pain-alleviating properties. This study aims to investigate the therapeutic effect of THP on diabetic neuropathic pain(DNP) and the underlying mechanism. High-fat and high-sugar diet(4 weeks) and streptozotocin(STZ, 35 mg·kg~(-1), single intraperitoneal injection) were employed to induce type-2 DNP in rats. Moreover, lipopolysaccharide(LPS) was used to induce the activation of BV2 microglia in vitro to establish an inflammatory cellular model. Fasting blood glucose(FBG) was measured by a blood glucose meter. Mechanical withdrawal threshold(MWT) was assessed with von Frey filaments, and thermal withdrawal latency(TWL) with hot plate apparatus. The protein expression levels of OX42, inducible nitric oxide synthase(iNOS), CD206, p38, and p-p38 were determined by Western blot, the fluorescence expression levels of OX42 and p-p38 in the dorsal horn of the rat spinal cord by immunofluorescence, the mRNA content of p38 and OX42 in rat spinal cord tissue by qRT-PCR, and levels of nitric oxide(NO), interleukin-1β(IL-1β), interleukin-6(IL-6), tumor necrosis factor-α(TNF-α), interleukin-10(IL-10), and serum fasting insulin(FINS) by enzyme-linked immunosorbent assay(ELISA). RESULTS:: showed that the mo-del group demonstrated significant decrease in MWT and TWL, with pain symptoms. THP significantly improved the MWT and TWL of DNP rats, inhibited the activation of microglia and p38 MAPK signaling pathway in rat spinal cord, and ameliorated its inflammatory response. Meanwhile, THP promoted the change of LPS-induced BV2 microglia from the pro-inflammatory M1 phenotype to the anti-inflammatory M2 phenotype, suppressed the activation of the p38 MAPK signaling pathway, decreased the expression levels of inflammatory factors NO, IL-1β, IL-6, and TNF-α, and increased the expression level of anti-inflammatory factor IL-10. The findings suggested that THP can significantly ameliorate the pain symptoms of DNP rats possibly by inhibiting the inflammatory response caused by M1 polarization of microglia via the p38 MAPK pathway.

Laparoscopic Roux-en-Y gastric bypass (RYGB) is an important obesity surgery. The risk of remnant gastric cancer after RYGB for obesity is gaining growing attention from bariatric surgeons and patients with obesity. This systematic review included articles from major databases internationally and domestically that specifically described the remnant gastric cancer after RYGB intervention, a total of 21 cases was subsequently analyzed. The average median time from post-operative RYGB to diagnosis of gastric cancer was 11 years (1-28 years), the duration of gastric cancer symptoms lasted 7 days to 6 years, abdominal pain is the most common (71.4%), especially in the upper abdomen (33.3%), followed by nausea and vomiting (33.3%), over-weight loss (33.3%), and abdominal bloating (28.6%), etc. Neoplasm location was reported to occur in the antrum or the pre-pyloric region (71.4%), with adenocarcinoma being the most common tumor histology observed (71.4%), tumor stage III-IV as the most diagnosed, 38.1% of tumor were deemed to be unresectable, 52.4% of the patients performed subtotal gastrectomy and lymphadenectomy. In addition, a global article investigating the occurrence of esophageal gastric cancer after RYGB in 64 cases revealed the common preoperative medical history include smoking habits (37.5%), alcohol issues (14.0%), GERD (86.0%), presence with Barret esophagus (10.9%), patients that has other malignant tumor medical history (6.3%), first-degree relatives (6.3%), or other family members with gastric esophagus cancer family history. Although the incidence of gastric cancer after RYGB is rare, the increasing prevalence of gastric cancer development is one of great concern. A rise in clinical cases of patients treated with RYGB presents a target for future studies. Risk of gastric cancer after RYGB should be evaluated and considered in high-risk cases.

Rhein is an anthraquinone compound extracted from rhubarb, aloe vera, Polygonum multiflorum. In this study, we screened the potential targets of rhein through protein chip technology and investigated the underlying mechanism of its inhibition of colorectal cancer. Colony formation assay and scratch assay were used to examine the effect of rhein on the proliferation and migration abilities of HCT116 cell; KEGG and protein interaction analyses of rhein specific binding proteins by screening rhein binding proteins using protein chip; qRT-PCR and Western blot assays were used to determine the effect of rhein on the expression levels of BCL-2-associated X protein (BAX), B-cell lymphoma-2 (BCL-2) and argininosuccinate synthetase 1 (ASS1) in HCT116 cell. The antitumor effect of rhein was verified by azoxymethane combined with dextran sodium sulfate (AOM/DSS) induced colorectal cancer model. Experimental animal procedures were performed in accordance with animal welfare and the standards of the Laboratory Animal Ethics Committee of South China Agricultural University, with approval from the ethics committee.

Objective: To evaluate the short-and mid-term efficacy of pediatric kidney transplantation and the risk factors for kidney graft and recipient. Methods: The baseline data and postoperative complications of pediatric donors and recipients of 284 kidney transplants were retrospectively analyzed in the Department of Kidney Transplantation in the First Affiliated Hospital of Zhengzhou University from August 2010 to May 2021 and all subjects were followed up until December 31, 2021. According to the survival status of donors and recipients, they were divided into the graft-loss group and the graft-survival group, and the recipient death group and survival group, respectively. Univariate comparison between groups was performed by Log-rank test, and Cox proportional risk model was used to explore the independent risk factors for the graft and recipient survival. Results: Among the 284 children recipients, 184 cases (64.8%) were male and 100 cases(35.2%) were female, and 19 cases (6.7%) were living relative donor renal transplantation, 19 cases (6.7%) were preemptive transplantation, and 8 cases were secondary transplantation. The age of 284 recipients at the time of transplantation was 13.0 (9.0, 15.0) years, among whom 29 cases aged 0-6 years, 96 cases aged 7-11 years old, and 159 cases aged 12-18 years. The 1, 3, and 5 year survival rates were 92.3%, 88.9% and 84.8% for the kidney grafts, and were 97.1%, 95.6% and 94.4% for the recipients, respectively. Multivariate analysis showed postoperative acute rejection (HR=3.14, 95%CI 1.38-7.15, P=0.006) and perioperative vascular complications (HR=4.73, 95%CI 2.03-11.06, P<0.001) were independent risk factors for the survival of kidney graft. Postoperative infection (HR=14.23, 95%CI 3.45-58.72, P<0.001) was an independent risk factor for the postoperative mortality of recipients. Conclusions: Pediatric kidney transplantation shows a good short-and mid-term prognosis. Postoperative acute rejection and perioperative vascular complications are the risk factors for the survival of kidney graft, and postoperative infection is the risk factor affecting the survival of recipient.

Traditional Chinese medicine (TCM) is a great treasure house, exhibiting unique advantages in the treatment of some difficult and critical diseases. The incidence rate of membranous nephropathy has increased year by year in recent years, and has become the first cause of primary glomerular diseases. However, its pathogenesis is not clear. Modern medicine often uses immunosuppressive therapy, but it often faces the problems of high side effects and high recurrence rate. The China Association of Chinese Medicine (CACM) invited clinical experts of TCM and western medicine to fully discuss membranous nephropathy, which was later confirmed to be one of the clinical diseases responding specifically to TCM. Apart from summarizing the pathogenesis and clinical diagnosis and treatment of membranous nephropathy in both TCM and western medicine, this paper also detailed TCM cognition, syndrome differentiation, and therapeutic schemes of membranous nephropathy, aiming to improve the clinical remission rate of membranous nephropathy and provide reference for its clinical treatment.

This study aimed to investigate the effect of methyl eugenol(ME) on hypoxia/reoxygenation(H/R)-induced injury of human renal tubular epithelial HK-2 cells and its mechanism. The viability of HK-2 cells cultured with different concentrations of ME and exposed to H/R was detected by cell counting kit-8(CCK-8) assay. The effect of ME on the morphology of HK-2 cells was observed under an inverted microscope. The content of intracellular reactive oxygen species in different groups was detected after 2',7'-dichlorodihydrofluorescein diacetate(DCFH-DA) fluorescence staining. Cell apoptosis was determined by flow cytometry. Changes in mitochondrial membrane potential were monitored by JC-1 dye. The concentrations of nuclear factor erythroid 2 related factor 2(Nrf2), heme oxygenase-1(HO-1), and nicotinamide adenine dinucleotide phosphatase oxidase 4(Nox4) were measured by Western blot, followed by the assay of Nrf2 concentration changes in cytoplasm and nucleus by confocal fluorescence staining. The results showed that when the concentration of ME was 0-40 μmol·L~(-1), the activity of HK-2 cells was not affected. Compared with the model group, ME enhanced the activity of HK-2 cells and the cell morphology was normal. As revealed by further experiments, ME inhibited the release of reactive oxygen species and the decline in mitochondrial membrane potential of HK-2 cells after H/R injury, promoted Nrf2/HO-1 expression and Nrf2 translocation to the nucleus, and down-regulated the expression of Nox4, thereby significantly reducing apoptosis. This protective effect of ME could be reversed by the specific Nrf2 inhibitor ML385. These findings have preliminarily proved that ME effectively protected HK-2 cells against H/R injury, which might be related to its promotion of Nrf2/HO-1 signaling pathway and inhibition of Nox4. Such exploration on the possible mechanism of ME in the treatment of renal ischemia-reperfusion injury(IRI) and protection of organ function from the perspective of antioxidant stress has provided reference for related research on the treatment of acute kidney injury with traditional Chinese medicine.

In recent years, with the development of laparoscopic technology and the improvement of surgeons' skill, laparoscopic radical gastrectomy for early gastric cancer has been widely achieved in large centers worldwide. But digestive reconstruction under laparoscopy is still the most important for totally laparoscopic surgery. At present, the oncological safety of totally laparoscopic gastrectomy for early gastric cancer has been preliminarily confirmed. Digestive tract reconstruction after totally laparoscopic distal gastrectomy includes Billroth-Ⅰanastomosis, Billroth-Ⅱ anastomosis and Roux-en-Y anastomosis; after proximal gastrectomy, it includes traditional esophagogastric anastomosis and evolutionary anti-reflux surgery;for total gastrectomy, itincludes esophageal jejunal anastomosis by using circular stapler and linear stapler. These reconstruction methods have their own characteristics, and no consensus has been reached at present. However, in clinical practice, it is necessary to focus on the patient, adjust measures to local conditions, and select the appropriate digestive tract reconstruction method on the premise of ensuring the radical cure of tumors.

To clarify the species and preparation of " Baihe"( Lilii Bulbus),a traditional Chinese medicine,we investigated the relative ancient Chinese literature on this medicine. The study concluded that Lilium brownii var. viridulum is the authentic lily for medical use. In the Ben Cao Yan Yi and some medical books in the Ming and Qing Dynasties,L. lancifolium( Juandan) was also mistakenly used as genuine lily,but most doctors believe that this variety should not be used for medicinal purposes; L. pumilum( Shandan)began to be used as a medicine from Ri Hua Zi Ben Cao,but mainly for surgery,the effect is also different from L. brownii var. viridulum. We suggested Shandan be used as the species for another medicine as " Hong Bai He( red lily) " due to its red flower. All above three species recorded in the Chinese Pharmacopoeia are not corresponded to the condition of ancient doctors' uses. Therefore,as for developing of traditional classical formula,L. brownii var. viridulum should be chosen and used as Baihe. The birth places for Baihe include Gansu,Hubei,Anhui and Shandong province. The drug preparations of Baihe include crude medicine,roasting and steaming,which preparation should be chosen depends on the formula which contains Baihe.
