Objective·To investigate the effect of neferine(Nef)on renal tissues of diabetic nephropathy(DN)rats and its related mechanism.Methods·DN model rats were constructed by feeding high-fat diet combined with intraperitoneal injection of streptozotocin,and the successfully constructed rats were randomly divided into DN group,Nef(low,medium and high)dose groups and Nef high-dose+pathway antagonist(AMD3100)group,with 10 rats in each group.At the same time,10 common rats were selected as the normal group.The levels of fasting blood glucose(FBG),24 h urinary protein,serum glycosylated hemoglobin(HbA1c),serum creatinine(Scr),blood urea nitrogen(BUN)and renal index of rats in the six groups were measured.Hematoxylin-eosin(H-E)and Masson staining were used to observe the pathological changes of renal tissues.The content of malondialdehyde(MDA)in renal tissues was determined by thiobarbituric acid(TBA)method,and the activities of superoxide dismutase(SOD)and catalase(CAT)in renal tissues were determined by water soluble tetrazolium(WST-1)method and ammonium molybdate method,respectively.The mRNA and protein expressions of stromal cell-derived factor-1(SDF-1)and CXC chemokine receptor 4(CXCR4)in renal tissues were detected by quantitative real-time PCR(qPCR)and Western blotting,respectively.Rat renal tubular epithelium cells NRK-52E were induced by high glucose(30 mmol/L glucose)to establish DN cell model.The cells were divided into control group,high glucose(HG)group,HG+Nef(low,medium and high)dose(i.e.HG+Nef-L,M and H)group,and HG+Nef-H +AMD3100 group.SOD and CAT activities were detected by WST-1 method and ammonium molybdate method,respectively.MDA content was detected by TBA method.The mRNA and protein expressions of SDF-1 and CXCR4 were detected by qPCR and Western blotting,respectively.CCK-8 method and flow cytometry were used to detect cell viability and apoptosis rate,respecti-vely.Results·Compared with the DN group,the levels of FBG,24 h urinary protein,HbA1c,Scr,BUN,renal index and MDA content in Nef(low,medium and high)dose groups and Nef high-dose+AMD3100 group were decreased,the mRNA and protein expressions of SDF-1 and CXCR4 were increased,and the activities of SOD and CAT were increased(all P<0.05).The degree of pathological damage and fibrosis of renal tissues was reduced;all of the above changes were dose-dependent.AMD3100 could weaken the renal protective effect of high-dose Nef on DN rats.Compared with the HG group,NRK-52E cell viability,SOD and CAT activities,and the mRNA and protein expressions of SDF-1 and CXCR4 were increased in HG+Nef-L,M and H groups,while apoptosis rate and MDA content were decreased(all P<0.05).AMD3100 could reverse the protective effect of Nef-H on NRK-52E cell damage.Conclusion·Nef may control blood glucose levels on DN rats and improve antioxidant capacity by activating the SDF-1/CXCR4 signal pathway,playing a renal protective role.

Objective:To investigate the clinical characteristics and prognosis of cytomegalovirus-sepsis-like syndrome (CMV-SLS) in premature infants, and to provide the evidence for early clinical identification and treatment.Methods:Premature infants with CMV-SLS admitted to Children′s Hospital Affiliated of Zhengzhou University from January 1, 2019 to December 31, 2022 were selected as the research subjects, and their clinical characteristics, treatment, and prognosis were retrospectively analyzed.Results:A total of seven cases of CMV-SLS were included, with a gestational age of (26.8±1.2) weeks and a birth weight of (890±121) g. The age of disease onset was 55(45, 60) days, and the age of diagnosis was 67(56, 71) days. All the seven cases were exclusively breast feeding after birth, and cytomegalovirus (CMV) DNA was detected positive in their breast milk when diagnosed with CMV-SLS. The common clinical features were fever, abdominal distension, liver function damage, decreased neutrophil and platelet counts. Pneumonia, neonatal necrotizing enterocolitis, hearing loss, and chorioretinitis were common. After the diagnosis was confirmed, all the seven cases were given intravenous treatment of ganciclovir and followed by oral formulations, with a course of treatment ranging from five to seven weeks. Two cases were treated with intravitreal injection of ganciclovir for chorioretinitis. All the seven cases survived. During the follow-up with a corrected gestational age of 12 months, one case had delayed intellectual and motor development, two cases had delayed motor development, and the remaining cases had normal development.Conclusions:CMV-SLS in premature infants mainly occurs in extremely low birth weight infants, with atypical clinical manifestations and may be misdiagnosed easily. If extremely low birth weight infants who receive CMV DNA positive breast feeding show sepsis-like symptoms, the possibility of CMV infection should be considered, and early diagnosis and treatment should be carried out to prevent adverse outcomes.

Objective:To investigate the clinical effect of homemade adjustable mirabilite vest in patients with severe acute pancreatitis and supply reference for clinical nursing.Methods:This was a randomized controlled study. One hundred patients with acute severe pancreatitis admitted to Putuo Hospital, Shanghai University of Traditional Chinese Medicine from January 2021 to June 2022 were selected, and were divided into the pocket group and the vest group according to the order of admission with 50 cases in each group. The pocket group used traditional mirabilite bag for external application, the vest group used adjustable mirabilite vest for external application. The other treatment measures were the same for both two group.

The difference were not statistically significant( P>0.05). After intervention, the comfort degree of the pocket group was (65.90 ± 7.95) points while the comfort degree of the vest group was (77.04 ± 5.96) points. The difference was statistically significant ( t = 7.93, P<0.01). The degree of pruritus was (12.72 ± 3.95) points in the pocket group and (8.00 ± 1.20) points in the vest group.The difference was statistically significant ( t = 8.08, P<0.05). The mean length of hospital stay in the pocket group was (15.86 ± 5.83) days and (11.02 ± 3.38) days in the vest group. The difference was statistically significant ( t = 5.08, P<0.01). Conclusions:When using topical mirabilite for patients with acute severe pancreatitis, the use of adjustable mirabilite vest can significantly improve patients′ comfort, reduce itching, and reduce the number of hospital days, which has the value of promotion and use.

This article reported a case of neonatal-onset autoinflammation with infantile enterocolitis (AIFEC) caused by NLRC4 gene mutation. The boy developed the disease in the neonatal period, presenting with recurrent fever, rash, hepatosplenomegaly and enterocolitis. Laboratory tests showed some indicators including ferritin and C-reactive protein were elevated. His condition was complicated by macrophage activation syndrome and anti-infective treatment was ineffective. High-throughput whole exome sequencing revealed a de novo heterozygous mutation of c.1021G>C (p.Val341Leu) in the NLRC4 gene and AIFEC was confirmed. AIFEC is a rare disease with no effective treatment at present, which can be developed in the neonatal period and diagnosed by whole exome sequencing.

OBJECTIVE: To determine the efficacy of second generation endometrial ablation (NovaSure) combined with levonorgestrel-releasing intrauterine system (Mirena) in the treatment of adenomyosis. METHODS: Clinical data of patients with adenomyosis admitted in Women's Hospital, Zhejiang University School of Medicine from January 2015 to December 2018 were retrospectively analyzed. Among 66 patients, 44 received Mirena placement only (control group) and 22 received Mirena placement and NovaSure treatment (study group). The menstruation blood loss, dysmenorrhea score, uterine size, expulsion rate of Mirena and the patients' satisfaction rate were assessed in two groups. RESULTS: There was a significant reduction in menstruation blood loss (<0.05) and significant improvement in dysmenorrhea (<0.05) after the treatment in both groups. The patients in study group had more marked improvement in menstruation blood loss than those in control group (<0.05). The patients' satisfaction was higher and the expulsion rate of Mirena was lower in study group than that in control group (all <0.05). The score of dysmenorrhea and the size of uterine had no significant difference between two groups (all >0.05). CONCLUSIONS NovaSure can improve the efficacy of Mirena in treatment of adenomyosis.

To study the protective effect of Xingnaojing Injection on early global brain ischemia-induced deep coma in rats.
 Methods: The deep coma model was induced by global brain ischemia by using four-vessel occlusion method in male SD rats. According to the body weight, the rats were randomly divided into 8 groups: a model control group, three different dose of Xingnaojing Injection (1.8, 3.6 and 5.4 mL.kg-1) groups, a Xingnaojing Injection (3.6 mL.kg-1) plus PI3K inhibitor group, a naloxone injection (0.04 mL.kg-1) group and a naloxone injection (0.04 mL.kg-1) plus Xingnaojing Injection (3.6 mL.kg-1) group (n=8 per group). In addition, eight animals served as the sham group were performed same operation with the model group excepting no blockage of the blood vessels. After the operation, three different doses of Xingnaojing Injection and/or naloxone injection were given intravenously once a day for three days. Ten μL PI3K inhibitor (LY294002, 10 mmol/L) was injected via anterior cerebral ventricle at once after global brain ischemia. The awakening time after the first drug treatment, the grasping power and the autonomous activity within 10 min after the last drug treatment were recorded. The levels of both dopamine (DA) and glutamate (Glu) in cerebrospinal fluid were detected by ELISA. The pathological changes were observed in brain tissue slices with HE staining and the protein levels of Akt/p-Akt and cAMP-response element binding protein (CREB)/p-CREB in hippocampus were detected by Western blotting.
 Results: Comparing with the model group, single administration of Xingnaojing Injection could significantly shorten the waking time (P<0.05) and continuous administration of Xingnaojing Injection for 3 d could increase grasping power, distance, frequency and duration of autonomous activities (P<0.05 or P<0.01) in the deep coma rat. Also, Xingnaojing Injection could inhibit these increases in neurotransmitters DA and Glu contents (P<0.05 or P<0.01), and improve pathological changes of hippocampal tissue. Xingnaojing Injection significantly induced protein phosphorylation of both Akt and CREB (P<0.05 or P<0.01); this effect was inhibited by PI3K inhibitor (P<0.05 or P<0.01). Moreover, the protective effects of naloxone on awakening time, grasping power, the autonomous activity and hippocampus damage in global brain ischemia-induced deep coma could be enhanced by joint use of Xingnaojing Injection (P<0.05 or P<0.01).
 Conclusion: Xingnaojing Injection could significantly improve deep coma induced by global brain ischemia in rat, which is related to inducing PI3K/Akt-dependent protein phosphorylation of CREB, and reducing hippocampal damage. The protective effect of Xingnaojing Injection is synergistically enhanced by naloxone.
