OBJECTIVE To investigate the relationship between the course of antibiotics during perioperative period and postoperative infection in pregnant women with human immunodeficiency virus/acquired immune deficiency syndrome(HIV/AIDS) undergoing cesarean section, and to guide the rational use of antibiotics in clinical practice. METHODS A total of 53 cesarean section women in the hospital from January 2014 to September 2022 were chosen as research objects. According to the course of antibiotics, the puerperae were divided into two groups. The treatment course of antibiotics in the study group(n=31) was >24 h and ≤48 h, and the control group(n=22) was ≤24 h. The postoperative wound healing, inflammatory indexes, postoperative infection rate, and postoperative hospital stay were observed. RESULTS There was no significant difference in postoperative body temperature, white blood cell count, neutrophil ratio, C-reactive protein, postoperative hospital stay, wound healing grade and postoperative infection rate between the study group and the control group. CONCLUSION Antibiotics for HIV/AIDS patients during perioperative period of cesarean section for <24 h may play a better role in preventing postoperative infection.

Objective To observe the effects of acupuncture at acupoints along the meridians on the expression of frontal lobe associated protein kinase in pchlorophenylalanine(PCPA)induced insomnia rats;To explore the mechanism of acupuncture in improving insomnia.Methods Totally 60 rats were randomly divided into blank group,model group,sham acupuncture group,acupuncture group and Western medicine group,with 12 rats in each group.An insomnia model rat was induced by intraperitoneal injection of PCPA.The acupuncture group received acupuncture at"Baihui","Shenmen"(bilateral),and"Sanyinjiao"(bilateral),while the sham acupuncture group only fixed the needle at the corresponding acupoints but did not penetrate the skin,while the model group was only fixed for 30 minutes,the Western medicine group was given a solution of estazolam by gavage for 7 consecutive days,the blank group was not treated.The pentobarbital sodium reversal experiment was used to detect the sleep latency and sleep time of rats,ELISA was used to detect the content of melatonin(MT)in plasma,RT-PCR was used to detect the mRNA expressions of calmodulin dependent protein kinase(CaMK)Ⅱ,protein kinase C(PKC)and p38 mitogen activated protein kinase(MAPK)in frontal lobe tissue,and Western blot was used to detect the protein expressions of CaMKⅡ,PKC and p38MAPK in frontal lobe tissue.Results Compared with the blank group,the sleep latency of the model group rats were significantly prolonged and the sleep time were significantly shortened(P<0.01),the content of MT in plasma was significantly reduced(P<0.01),and the mRNA and protein expressions of CaMKⅡ and PKC in frontal lobe tissue were significantly decreased(P<0.01),the mRNA and protein expressions of p38MAPK were significantly increased(P<0.01).Compared with the model group,the sleep latency were significantly shortened and the sleep time were significantly prolonged in the acupuncture group and the Western medicine group(P<0.01),the plasma MT content significantly increased(P<0.01),the mRNA and protein expressions of CaMKⅡ and PKC in frontal lobe tissue significantly increased(P<0.05),and the mRNA and protein expression of p38MAPK significantly decreased(P<0.01).Compared with the sham acupuncture group,the sleep latency shortened and sleep time were significantly prolonged in the acupuncture group and the Western medicine group(P<0.01),plasma MT content significantly increased(P<0.01),PKC mRNA expression in frontal lobe tissue significantly increased(P<0.01),and p38MAPK mRNA expression significantly decreased(P<0.01).There was no statistically difference in various indicators between the acupuncture group and the Western medicine group(P>0.05).Conclusion Acupuncture at acupoints along the meridians can shorten the sleep latency and prolong sleep time,improve sleep status by regulating the expression of associated protein kinase in frontal lobe of insomnia rats.

Objective:To investigate impacts of paeoniflorin-6′-O-benzene sulfonate(CP-25)on proliferation and apoptosis of ovarian cancer cells through Toll-like receptor 4(TLR-4)/nuclear factor-κB(NF-κB)signaling pathway.Methods:CCK-8 assay was performed to measure the cell activity of human ovarian cancer cells A2780,SK-OV-3,HO8910 and normal ovarian cells HOSEpiC.A2780 cells were separated into control group(0.01%DMSO),CP-25 low(0.5 mg/ml CP-25),medium(1 mg/ml CP-25)and high(2 mg/ml CP-25)concentration groups and CP-25 high concentration+LPS group(2 mg/ml CP-25 and 0.1 μg/ml TLR-4 activator LPS).Cell proliferation was evaluated by CCK-8 and clone formation assays;cell apoptosis was analyzed by flow cytometry and TUNEL staining;proliferating protein Ki67,apoptosis-related proteins(Cleaved caspase-3,Caspase-3,Bax,Bcl-2),TLR-4,p-NF-κB p65,NF-κB p65 protein expression levels were analyzed by Western blot;protein expressions of TLR-4 and NF-κB p65 were observed by immunofluorescence staining.Results:Compared with HOSEpiC cells,viabilities of A2780,SK-OV-3 and HO8910 cells were reduced gradually with the increased of CP-25 concentration(P<0.05),and CP-25 had about 50%inhibitory effect on the growth of A2780 cells at low,medium and high concentrations,so A2780 cells were used for the experiments.Compared with control group,the clone formation rate of A2780 cells in low,medium and high concentration groups of CP-25 reduced obviously,while apoptosis rate and apoptosis index rose obviously,expression levels of Ki67,Bcl-2,TLR-4,p-NF-κB p65 and nuclear NF-κB p65 were reduced obviously,while expression of Cleaved caspase-3/Caspase-3 and Bax were increased obviously in a concentration-dependent manner(P<0.05).Compared with CP-25 high concentration group,cell viability and clone formation rate were significantly increased in CP-25 high concentration+LPS group,while apoptosis rate and apoptosis index were decreased significantly,expression levels of Ki67,Bcl-2,TLR-4,p-NF-κB p65 and nuclear NF-κB p65 were increased significantly,while expressions of Cleaved caspase-3/Cas-pase-3 and Bax were significantly decreased(P<0.05).Conclusion:CP-25 inhibits ovarian cancer cell proliferation and promotes apoptosis by inhibiting TLR-4/NF-κB signaling pathway.

Objective To explore the predictive value of 3D quantitative shape features based on enhanced CT for disease-free survival(DFS)of primary gastric gastrointestinal stromal tumors(GIST)patients receiving curative resection.Methods From January 2010 to December 2016,a total of 154 patients with primary gastric GIST who received curative resection in Zhongshan Hospital,Fudan University were retrospectively collected.The conventional CT imaging features and 3D quantitative shape features of tumors were evaluated,and the influencing factors of DFS were analyzed by univariate and multivariate Cox regression.Cut-off values were extracted,and Kaplan-Meier curves were used for survival analysis.Results Maximum 3D diameter(HR=1.829,95% CI 1.389-2.408,P＜0.001)and spherical disproportion(HR=2.153,95% CI 1.474-3.146,P＜0.001)were independent risk factors for DFS in primary gastric GIST.Kaplan-Meier curves showed that patients with maximum 3D diameter＞90.5 mm and spherical disproportion＞1.5 showed shorter DFS after curative resection(P＜0.001).Conclusion Maximum 3D diameter and spherical disproportion based on preoperative enhanced CT are valuable in the diagnosis of postoperative DFS in primary gastric GIST.

Objective: To explore the surgical methods and clinical outcomes of severe angular kyphosis with the length of the spinal cord constant in the osteotomy area. Methods: Clinical data from 20 patients with severe angular kyphosis who underwent surgical treatment from January 2017 to December 2020 in the Department of Spinal Surgery,Hangzhou Xiaoshan District Hospital of Traditional Chinese Medicine were retrospectively analyzed. There were 11 males and 9 females, aged (28.5±8.9) years (range:17 to 46 years).There were 15 cases with congenital angular kyphosis,5 cases with tuberculous angular kyphosis.The angle of kyphosis was (107.1±12.9)° (range:93.2° to 131.4°).Frankel classification:2 cases with grade B,4 cases with grade C,3 cases with grade D.The kyphotic vertex is located at the T₉ to T₁₂ segments.Pedicle screws were placed in 3 or 4 adjacent segments at the proximal and distal kyphosis apex of the patients using a surgical navigation system.Piezosurgery combined with a grinding drill was used to complete the osteotomy in the apical vertebral region.Titanium mesh or artificial vertebral body was implanted,and the osteotomy surface was closed using this as the fulcrum to complete osteotomy.Spinal X-ray examination was performed before surgery,immediately after surgery and at the last follow-up,and sagittal and coronal Cobb angle,sagittal and coronary balance parameters,anterior vertebral height,posterior vertebral height,and spinal cord length were measured.Pulmonary function,visual analogue scale (VAS),and Oswestry's disability index (ODI) were collected and estimated before and after treatment.The analysis of variance of repeated measurement data was used for each evaluation index before and after treatment,and the t test was used for pairwise comparison. Results: All patients successfully completed surgery,with artificial vertebral body in 11 cases and double titanium mesh in 9 cases.The follow-up time was (28.2±2.3) months (range:26 to 31 months).Sagittal vertical axis improved from (46.9±13.7)mm(range:21.7 to 75.7 mm) before surgery to (10.7±5.5)mm (range:3.6 to 28.1 mm) after surgery,and (11.0±5.7)mm(range:3.6 to 29.3 mm) at the last follow-up,the differences were statistically significant compared to before surgery (all P<0.01).The mean kyphotic Cobb angle was corrected from (107.1±12.9) ° (range:93.2 ° to 131.4°) before surgery to (30.6±8.5) ° (range:20.0 ° to 47.8 °) after surgery (all P<0.01),and (32.1±8.7) ° (range:18.2 ° to 50.8°) at the last follow-up,the differences were statistically significant compared to before surgery(all P<0.01).The anterior vertebral height improved from (14.2±2.9)mm(range:11.04 to 23.6 mm) before surgery to (45.3±7.5)mm(range:29.4 to 56.5 mm) after surgery,and (44.3±6.8)mm(range:29.6 to 56.0 mm) at the last follow-up,the differences were statistically significant compared to before surgery (all P<0.01).The posterior vertebral height was improved from (51.8±5.3)mm (range:43.1 to 61.4 mm)before surgery to (57.6±4.7)mm (range:45.7 to 64.1 mm)after surgery,and (56.3±5.0) mm (range:49.7 to 68.5 mm) at the last follow-up,the differences were statistically significant compared to before surgery (all P<0.01).The spinal cord length of the osteotomy segment was (73.1±12.0)mm (range:56.8 to 98.4 mm) before surgery and (74.8±12.8)mm (range:53.5 to 100.2 mm) after surgery and (75.2±13.7)mm (range:53.9 to 102.4 mm) at the last follow-up,the difference was not statistically significant among them(F=0.144,P=0.866).The ODI and VAS scores improved significantly after surgery and at the last follow-up,and the differences were statistically significant (all P<0.01). Conclusion: The posterior vertebral column resection technique combined with titanium mesh or an artificial vertebral body implant for the treatment of severe angular kyphosis can significantly improve the kyphosis,neurological function,and life quality of patients without affecting the length of the spinal cord.

ObjectiveTo summarize the research progress of mammalian target of rapamycin （mTOR） pathway regulated by traditional Chinese medicine（TCM） and provide reference for visualization and quantitative analysis of related research based on multiple software linkage. MethodLiterature related to TCM regulation of mTOR pathway in Web of Science was taken as the research object. Citespace，VOSviewer，and carrort² were used for biliometric analysis and visualization of the literature. ResultA total of 245 papers that met the requirements were retrieved，and the visual analysis showed that the papers presented a fluctuating increase year by year after 2010，and numerous research results emerged in 2018. China had the most publications. Institutions with a large number of publications were mainly in Beijing and Shanghai，and most of the regional cooperation was centered in Beijing and Nanjing. According to the research direction and focus，it was found that the intervention of TCM in mTOR pathway in recent years mainly concentrated on the anti-tumor，anti-apoptotic and anti-inflammatory aspects， and TCM interfered with mTOR pathway to regulate cell apoptosis，autophagy，proliferation，and death. AMP-activated protein kinase （AMPK） and phosphatidylinositol 3-kinases（PI3K）/protein kinase B（Akt）/mTOR pathway were the current and future research hotspots. ConclusionResearch on the regulation of mTOR pathway by TCM had a good prospect，and the in-depth study might provide new ideas and guidance for the treatment of cardiovascular diseases，tumor and other major diseases.

The paper summarizes the clinical and follow-up data of percutaneous endoscopic gastrostomy (PEG) in three infants with chronic kidney disease to explore the safety and reliability of using PEG to improve the growth and development, and nutritional status. During follow-up, the weight and height of case 1 and 3 were obviously improved. Case 2 was followed up for 3 months, due to dying of cardiac arrest, and the infant's height and weight were not significantly improved. Serum albumin and prealbumin improved in 3 cases after PEG. No PEG-related infection occurred in 3 infants.

AIM: To investigate the anesthetic effect of remimazolam tosilate combined with remifentanil in elderly patients undergoing spinal surgery, and its impacts on hemodynamics, serum interleukin-1β (IL-1β) and C-X-C motif chemokine ligand 8 (CXCL8) level. METHODS: A total of 88 elderly patients who underwent spinal surgery in our hospital from May 2022 to May 2023 were randomly separated into an experimental group and a control group. The control group was given remifentanil, and the experimental group was anesthetized with remimazolam tosilate on the basis of the control group. The anesthesia effect, hemodynamic indicators, serum IL-1β and CXCL8 levels, and complication rate were compared between two groups. RESULTS: After different anesthesia regimens, the recovery time of spontaneous respiration, extubation time, and recovery time of the two groups were compared, and the experimental group were obviously shorter than the control group (P<0.05); compared with pre administration (T0), the fluctuation ranges of hemodynamic indexes, including heart rate (HR) and mean arterial pressure (MAP), in the experimental group after 1 min (T1), 5 min (T2), 10 min (T3) and after extubation (T4) of administration were obviously lower than those in the control group (P<0.05). After surgery, the levels of IL-1β and CXCL8 in the serum of the two groups obviously increased (P<0.05), but the experimental group showed a obvious decrease compared to the control group (P<0.05); there was no significant difference in the incidence of complications between the two groups (P>0.05). CONCLUSION: The combined anesthesia of remimazolam tosilate and remifentanil has an ideal effect and high clinical application value for elderly patients undergoing spinal surgery.

OBJECTIVE To investigate the role of clinical pharmacists in the treatment of a patient with Epstein-Barr （EB） virus encephalitis. METHODS Clinical pharmacist participated in drug diagnosis and therapy for a patient with EB virus encephalitis. According to the physiological characteristics of the disease and the pharmacokinetic-pharmacodynamic characteristics of antibiotics， clinical pharmacists suggested that the dose should be adjusted as ceftriaxone 2 g， q12 h+meropenem 2 g， q8 h. Based on the uncontrolled infection of the patient， pharmacists suggested that ceftriaxone should be stopped and vancomycin 1 million U and q12 h should be used as alternative therapy. According to the results of etiology， pharmacists suggested that acyclovir should be discontinued and replaced with ganciclovir 5 mg/kg， q12 h. The electrolyte disturbance of the patient may be adverse drug reactions caused by Mannitol injection， it was recommended to stop the drug. RESULTS The clinician followed the advice of the clinical pharmacists. After treatment， the patient improved and was discharged. CONCLUSIONS Clinical pharmacists can carry out pharmaceutical care for patients with EB virus encephalitis， assist physicians in optimizing the treatment plan of patients， and ensure the effectiveness and safety of drug treatment.
