This study was aimed to observe the effect ofZi-Bu Pi-Yin Recipe (ZBPYR) on the mRNA expressions of NMDA receptor subunits NR1, NR2A, NR2B in different brain regions of spleen-yin deficiency Alzheimer's Disease (AD) model rats. The levels of NR1, NR2A, NR2B mRNA expressions were detected by using RT-PCR method. The results showed that the levels of NR1, NR2A, NR2B mRNA expressions of AD group and spleen-yin deficiency AD group decreased significantly (P < 0.05). The levels of NR1, NR2A, NR2B mRNA expressions of ZBPYR treatment group increased significantly (P < 0.05). It was concluded that the expression levels of NMDAR mRNA in different brain regions of the ZBPYR treatment group increased significantly, which indicated that ZBPYR may up-regulate the protein expressions of NMDAR by increasing the expression levels of NMDAR mRNA, thereby to play the anti-dementia effect.

This study was aimed to observe the changes of dendritic spine density in different regions of brain among spleen-yindeficiency dementia (SYDD) model rats, in order to investigate the effects ofZi-Bu Pi-Yin Recipe (ZBPYR) on dendritic spines. Spleen-yindeficiency (SYD) rats were modeled by classical method. And incubatedβ-Amyloid 1-40 (Aβ1-40) was injected into the hippocampus of each rat to make SYDD model, which received the administration of ZBPYR. Golgi staining was used to stain dendritic spine in different regions of brain in rat model for the observation of the amount and shape. The results showed that dendritic spine density in different regions of hippocampus and cortex in SYDD group was reduced than that of the SYD group. Compared with the dementia group and the SYDD group, the dendritic spine density in different regions of hippocampus and cortex of the SYDD + ZBPYR group was increased. Compared with the blank control group, the dendritic spine density in different regions of hippocampus and cortex in rats from the dementia group was reduced. It was concluded that there were different degrees of reducing in the dendritic spine density of different brain regions in SYDD group. ZBPYR improved the learning and memory impairment, which might be related to the maintenance of dendritic spine density in different brain regions.

OBJECTIVETo study the expression of HBsAg and HBcAg in hepatocytes in CHB patients, and analyze the correlation among the expression of HBsAg and HBcAg, the quantity of HBV DNA in serum, the pathology of liver tissue and the clinical manifestation.
METHODSQuantitative polymerase chain reaction was used to assay the quantity of HBV DNA in serum in 351 CHB patients. Furthermore pathological diagnosis was performed using liver biopsy to assay the expression of HBsAg and HBcAg in hepatocytes by an immunohistochemical staining technique.
RESULTSThe positive expression rate of HBsAg and HBcAg in hepatocytes was 92.3% and 76.9% respectively. Cytoplasm-membrane HBcAg expression type (75.6%) was observed in the CHB with more active inflammation, while Nucleus HBcAg expression type (24.4%) was observed in the CHB with more sedative one (P < 0.0001). The expression of HBsAg was correlated with the quantity of HBV DNA in serum (rp = 0.24, P = 0.0129), while inversely correlated with the inflammation and the fibrillation of liver tissue (rp = -0.22, P = 0.0279; rp = -0.23, P = 0.0186). The expression of HBcAg was correlated with the quantity of HBV DNA in serum (rp = 0.52, P < 0.0001), while was inversely correlated with the inflammation and the fibrosis of liver (rp = -0.33, P < 0.0001; rp = -0.34, P < 0.0001).
CONCLUSIONCytoplasm-membrane HBcAg expression type was observed in the CHB with more active inflammation, while Nucleus HBcAg expression type was observed in the CHB with mild change. In the immunopathogenesis of the liver damage in CHB, HBcAg might be a main target antigen. HBsAg might be a sensitive index to screen HBV infection; HBcAg might probably be a reliable index to evaluate the replication of HBV

Objective:In order to analyze the current research status of handover shift in nursing management, summarize, analyze and judge the existing literature, in order to provide reference for clinical nursing practice.Methods:Through literature review, it is planned to review the current situation, shortcomings and future development of nursing handover classes.Results:The handover process was generally divided into four stages, of which SBAR was the best practice tool for handing over key information. For the performance of handover shifts, NASR, PVNC-BR, HES and Handoff CEX were often used to evaluate the performance of shifts, and for the results of shifts, evaluations were mostly conducted at the levels of patient safety, process elements, and organizational management. At present, the use of electronic information systems, benign organizational culture and patient and family-centered clinical practice could effectively improve the efficiency and effectiveness of handover.Conclusions:The process and elements of the current shift mode are relatively complete, and the communication strategy is reasonable, but there are still many shortcomings and defects. This suggests that nursing managers should adopt scientific intervention methods and evaluation tools when paying attention to and reforming nursing handover in the future to continuously improve the quality of handover.

Objective:To evaluate the effects of remimazolam on gastrointestinal motor function in the patients undergoing gastrointestinal endoscopy.Methods:A total of 262 American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ patients, aged 18-64 yr, with body mass index of 18-28 kg/m 2, scheduled for elective gastrointestinal endoscopy from May 2022 to August 2022, were divided into 2 groups ( n=131 each) using a random number table method: remimazolam group (group R) and propofol group (group P). The patients in group R received intravenous remimazolam 0.20-0.25 mg/kg, and patients in group P received intravenous propofol 1.5-2.0 mg/kg. The gastrointestinal endoscopy was performed when the patients′ Modified Observer′s Assessment of Alertness/Sedation scores ≤3. During fasting before gastrointestinal preparation, before gastrointestinal endoscopy and while leaving the post-anesthesia care unit (PACU), the concentrations of serum motilin and gastrin were measured by enzyme-linked immunosorbent assay, the intestinal peristalsis rating assessed by the endoscopist during the examination was recorded, the occurrence of hypotension and hypoxemia during the examination and occurrence of abdominal distension, abdominal pain, and nausea and vomiting during stay in PACU were recorded. Results:Compared with group P, the intestinal peristalsis rating was significantly increased, the serum motilin and gastrin concentrations were increased while leaving PACU, the incidence of hypotension and hypoxemia was decreased during the examination, and the incidence of abdominal distention was decreased during stay in PACU in group R ( P<0.05). Conclusions:Remimazolam has a milder inhibitory effect on secretion of gastrointestinal hormones than propofol in the patients undergoing gastrointestinal endoscopy and is helpful for the recovery of gastrointestinal motility.

Objective We aimed to elucidate the prevalence and the antibiotic resistance spectrum of nasal coagulase-negative staphylococci (CoNS) colonization among HIV infectors in Guangzhou. Method After isolation and identification, all CoNS isolates were tested for the antibiotic susceptibility, and the antibiotic resistance genes. Result Among the 1 001 HIV infectors, the prevalence of CoNS and MRCoNS were 57.44% and 48.15%, respectively. The three predominant resistant antibiotics of MRCoNS isolates were penicillin, erythromycin and trimethoprim-sulfame thoxazole, while predominant detection rates of genes were Aac(6’)-aph(2’)、ermC and linA genes. The multidrug resistance rate of MRCoNS isolates were significantly higher than methicillin-susceptible coagulase-negative staphylococci (MSCoNS) isolates (80.69% versus 39.66%, P<0.001, OR=6.36). Conclusions The prevalence and multidrug resistant rates of nasal colonization CoNS and MRCoNS are high among HIV infectors in Guangzhou. MRCoNS isolates were 6.36 times more likely to be of multidrug resistance than MSCoNS isolates.
