When partial nephrectomy is performed by posterior abdominal approach, the surgical field is poorly exposed, resulting in increased surgical difficulty and risk of injury.In this study, 28 patients with T 1a stage kidney tumors underwent retroperitoneal laparoscopic partial nephrectomy. Intraoperatively, exposure of the surgical field was achieved using the percutaneous puncture of the renal fascia suspension technique. There were no dissatisfactory exposures due to peritoneal damage during the surgery, no additional tubes were inserted, and no conversions to open surgery were needed. The operation time was (76.5±20.3) minutes, blood loss was (92.1±18.7) ml, renal artery clamping time was (19.5±4.3) minutes. Postoperatively, there were no complications such as bleeding, infection, or hematuria.

ObjectiveTo observe the effects of the South African herb Hoodia gordonii (HG) on glucolipid metabolism in diabetic db/db mice and explore the possible mechanisms of HG on the liver of db/db mice based on the phosphoinositide-3 kinase (PI3K)/protein kinase B (Akt)/factor forkhead protein O1 (FoxO1) signaling pathway. MethodA total of 30 db/db mice were randomly divided into five groups according to fasting blood glucose: model group, metformin group (0.195 g·kg-1), and low dose (0.39 g·kg-1), medium dose (0.78 g·kg-1), and high dose (1.56 g·kg-1) HG groups, with six m/m mice in each group, and another six m/m mice were set as normal group. The mice in the normal and model groups were given saline of 9 mL·kg-1 by gavage. Body weight, water intake, and fasting blood glucose of the mice in each group were measured weekly. After six weeks of continuous administration, serum insulin (FINS), low-density lipoprotein cholesterol (LDL), total cholesterol (TC), triglyceride (TG), alanine aminotransferase (ALT), aspartate aminotransferase (AST), urea, and creatinine (CREA) were measured, and liver sections were embedded and stained with hematoxylin-eosin (HE), periodic acid-Schiff (PAS), and oil red O. Protein expression of PI3K p85, p-Akt, and p-FoxO1 in liver was detected by immunohistochemistry. The mRNA expression of PI3K, Akt, and FoxO1 in liver tissue was detected by real-time polymerase chain reaction (Real-time PCR). ResultAfter six weeks of administration intervention, it was found that fasting blood glucose was significantly downregulated in mice in the three HG groups (P<0.05). The level of islet resistance index was significantly reduced in both the low and medium dose HG groups (P<0.05). The expression levels of TC, TG, and LDL were reduced in all HG groups (P<0.05, P<0.01). Pathologically, HG could alleviate hepatocyte steatosis, reduce the volume and content of lipid droplets in liver, and increase the distribution of glycogen granules in liver to some extent in mice. Immunohistochemical assays revealed that PI3K p85 protein expression was significantly increased in the low, medium, and high dose HG groups compared with the model group (P<0.01). p-Akt protein expression was significantly increased in the medium and high dose HG groups (P<0.05, P<0.01). p-FoxO1 protein expression was significantly increased in the low, medium, and high dose HG groups (P<0.05, P<0.01). Compared with the model group, PI3K mRNA was increased in low dose, medium dose, and high dose HG groups (P<0.05), and Akt mRNA was increased in high dose HG group (P<0.05). FoxO1 mRNA was decreased in low dose, medium dose, and high dose HG groups (P<0.05). ConclusionHG can ameliorate the disorder of glucolipid metabolism in db/db mice, which may be related to its activation of the hepatic PI3K/Akt/FoxO1 signaling pathway.

Objective:To understand the whole genome and genetic evolution characteristics of the first epidemic influenza A (H3N2) viruses in Wuxi from 2022-2023.Methods:Real time fluorescence quantitative RT-PCR method was used to perform typing on respiratory samples of influenza cases. Virus isolation was performed on samples with positive nucleic acid of subtype A H3N2 influenza virus detected. After cell culture, nucleic acid was extracted from strains with red blood cell agglutination test (HA) ≥ 1∶8, whole genome sequence was amplified, library was constructed, and computer sequencing was performed using MiSeq sequencer. Using NC_007366.1 as reference strain, the data were analyzed using CLC Genomics Workbench (Version 23) software. The phylogenetic tree was constructed using MEGA 7.0 software, and the N-glycosylation sites were predicted by NetNGlyc 1.0 Server software.Results:The nucleotide homology and amino acid homology among 35 strains of influenza A H3N2 virus from 2022 to 2023 were 96.4%-100% and 95.2%-100%, respectively. The 16 epidemic strains in 2022 belong to the 3C.2a1b.2a.1a evolutionary branch, while the 19 epidemic strains in 2023 belong to the 3C.2a1b.2a.2a.3a.1 evolutionary branch. There are 7 differences in the nucleotide sequence of the HA gene between the 2022 epidemic strain and the corresponding vaccine strain, sharing 15 mutation sites; There are 28 differences in the nucleotide sequence of the HA gene between the 2023 epidemic strain and the corresponding vaccine strain, sharing 17 mutation sites. The HA genes of 35 epidemic strains all lack N-glycosylation site 61: NSS, while in 2023, the HA genes of 19 epidemic strains added N-glycosylation site 110: NSS.Conclusions:The HA and NA genes of influenza A H3N2 virus in 2022 and 2023 belong to two evolutionary branches, respectively, and both show specific amino acid site changes compared to the corresponding vaccine strains. The antigen matching between the 2022 epidemic strain and the vaccine strain is relatively good, while there is a risk of low antigen matching between the 2023 epidemic strain and the vaccine strain.

ObjectiveTo observe the glucose-lowering, insulin resistance-improving, and anti-inflammatory effects of flavonoids from mulberry leaves (FML) and explore their underlying mechanism. MethodMale db/db mice aged 6-7 weeks were randomly divided into a model group, a high-dose FML group (1.00 g·kg·d-1), and a low-dose FML group (0.50 g·kg-1·d-1). C57BL mice of the same age were assigned to the normal group. After six weeks of intervention, fasting blood glucose (FBG), serum fasting insulin levels (Fins), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), free fatty acid (FFA), blood creatinine (SCr), blood urea nitrogen (BUN), and aspartate aminotransferase (AST) levels were measured, and the homeostasis model assessment of insulin resistance (HOMA-IR) was calculated. Superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and catalase activities in the liver were measured. Morphological changes in the liver were assessed by hematoxylin-eosin (HE) staining. The protein expression of cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS), and nuclear factor-κB (NF-κB) in the liver was detected by Western blot. ResultCompared with the model group, the high-dose and low-dose FML groups showed significant reductions in FBG, Fins, HOMA-IR, IL-6, TNF-α, and FFA levels (P<0.05, P<0.01), and increased levels of SOD, GSH-Px, and catalase in the liver (P<0.05, P<0.01). HE staining of the liver in the FML groups showed improved arrangement of hepatocytes, reduced inflammatory cell infiltration, and alleviated cellular steatosis compared with the model group. The protein expression of COX-2, iNOS, and NF-κB in the liver significantly decreased in the FML groups as compared with that in the model group (P<0.05, P<0.01). ConclusionFML have glucose-lowering and insulin resistance-improving effect, which may be attributed to their regulation of the NF-κB pathway in the liver of diabetic mice, leading to the suppression of the release of COX-2, iNOS, and inflammatory cytokines, thereby improving the inflammatory state.

ObjectiveTo observe the effect of Momordica charantia extract (MCE) on the gluconeogenesis signaling pathway in diabetes rats. MethodMale Zucker Diabetic Fatty (ZDF) rats aged 5-6 weeks were randomly divided into a model group and an MCE group (administered MCE at a dose of 0.40 g·kg-1 by gavage). Additionally, seven healthy male ZDF (fa/+) rats were assigned to the normal group and received administration once daily for six consecutive weeks. During the experiment, the general condition of the rats was observed, and body weight was recorded. Fasting blood glucose and random blood glucose levels were measured in the 1st, 3rd, and 5th weeks. In the 6th week, an oral glucose tolerance test (OGTT) was conducted, and serum levels of triglycerides (TG), free fatty acid (FFA), total cholesterol (TC), aspartate aminotransferase (AST), and alanine aminotransferase (ALT) were measured. Hematoxylin-eosin (HE) staining was performed to examine liver morphology, periodic acid-Schiff (PAS) staining was used to assess hepatic glycogen storage, and Real-time polymerase chain reaction (PCR) was employed to measure the mRNA expression of phosphoenolpyruvate carboxykinase (PEPCK) and glucose-6-phosphatase (G6Pase) in the liver. Western blot analysis was conducted to measure the phosphorylation level of forkhead box protein O1 (FoxO1) and the protein expression of PEPCK and G6Pase in the liver. ResultCompared with the model group, the MCE group showed significant improvements in body weight, fasting blood glucose, random blood glucose, and glucose tolerance (P<0.05, P<0.01) and reduced serum levels of FFA, TC, and TG (P<0.05, P<0.01). There were no significant differences in ALT and AST between the two groups. In the MCE group, the HE staining revealed more orderly liver cell arrangement and reduced hepatic steatosis and the PAS staining showed increased hepatic glycogen storage. The protein expression of p-FoxO1 in the liver was significantly elevated (P<0.01), while there was no significant difference in FoxO1 protein expression. The mRNA and protein expression of PEPCK and G6Pase significantly decreased (P<0.05). ConclusionMCE exhibits glucose-lowering and lipid-lowering effects, improves glucose tolerance, and enhances hepatic glycogen storage. These effects may be attributed to the upregulation of p-FoxO1, leading to the inhibition of PEPCK and G6Pase expression and the regulation of gluconeogenesis-related processes.

ObjectiveTo investigate the social support status and influencing factors of schizophrenics in remission in Northeast Sichuan, and to provide ideas for improving their social support. MethodsFrom May to September 2020, a total of 533 patients who met the diagnosis criteria of the International Classification of Diseases, tenth edition (ICD-10) for schizophrenics in remission at the mental health institutions in Guangyuan, Bazhong and Dazhou cities were selected for the survey, and patients were assessed by self-made demographic and clinical data inventory and Social Support Rating Scale (SSRS). Then the social support status of schizophrenic in remission and influencing factors were analyzed, meantime, the impact of the second round reimbursement policy of medical insurance benefits on their social support was addressed particularly. Results①The SSRS total score, objective support, subjective support, and utilization of support scores of schizophrenics in remission were lower than those of the national norm (t=5.065~30.382, P<0.01). ②Univariate analysis showed that SSRS score was relatively high among patients with female gender (t=-3.632), retired status (F=5.951), married status (F=5.951), spouse as primary caregiver (F=23.841), annual household income >5 000 yuan (F=15.892), patient's economic income (t=4.083), and outpatient or online follow-up (F=3.954), with statistically significant differences (P<0.05 or 0.01). ③The total and dimensional scores of SSRS in patients with access to the second round medical insurance reimbursement were significantly higher than those without (t=10.195~25.103, P<0.01). ④Multiple linear regression analysis denoted that gender, work status, marital status, primary caregivers, annual family income, economic income, follow-up visits and the second round medical insurance reimbursement were the factors influencing social support status of schizophrenics in remission (β=0.201~2.115, P<0.05 or 0.01). ConclusionThe social support of schizophrenics in remission in Northeast Sichuan is below the national average, furthermore, their social support levels are affected by the gender, work status, marital status, primary caregivers, annual family income, economic income, follow-up visits and the second round medical insurance reimbursement, and the second round medical insurance reimbursement may ameliorate the social support status of patients.

The human health is seriously affected by central nervous system(CNS) diseases, but the pathogenesis of CNS diseases is still not completely clear. Currently, the drugs used to treat CNS diseases are mainly receptor modulators and neurotransmitter inhibitors, which have serious side effects; and there are short of drugs for treating CNS diseases clinically. Studies suggest that animal medicines mainly include protein, polypeptide and small-molecule compounds, and have such pharmacological effects in calming, resisting convulsions and improving brain tissues. Plenty of studies suggest that animal medicines usually have a strong activity and good curative effect on these diseases, with a promising prospect in research and development of drugs treating CNS diseases. Based on systematic reviews of literatures, this paper summarizes active ingredients and main pharmacological effects of animal medicines in "extinguishing wind to arrest convulsions" for the CNS diseases, epilepsy and cerebral ischemia, and discusses their study value and application prospects. The results showed that the studies of protein and peptides were relatively simple, and some animal medicines were still blank. The authors believed that amino acids and small molecular compounds should be transferred to oligopeptide, advanced protein extraction and separation techniques shall be adopted for identifying the protein polypeptide composition structure and studying the efficacy, and the methods of biological technology were used to develop peptide biological products for the treatment of CNS diseases. This paper could provide ideas and reference for developing animal medicine products for the treatment of CNS diseases.
