ObjectiveTo study the effect of Wulingsan on cerebral edema after intracerebral hemorrhage （ICH） in mice and explore the treatment mechanism. MethodsThe mouse model of ICH was established by injection of collagenase into the caudate nucleus. Mice were randomly assigned into the following groups： sham， ICH， intervention before modeling with low-dose and high-dose （3.69， 11.07 g·kg^-1， respectively） Wulingsan， and intervention after modeling with high-dose Wulingsan. The modified neurological severity score （mNSS） was recorded， and the small animal MRI T2 sequential scanning was performed to measure the volume of cerebral hemorrhage after the modeling of ICH in each group. The Y-maze test， open field test， and Morris water maze test were conducted to evaluate the neurological behaviors of mice in each group. Hematoxylin-eosin staining was employed to observe the pathological changes in the brain tissue. Immunohistochemistry was employed to observe the expression of aquaporin 4 （AQP4）， neuronal nuclei （NeuN）， and glial fibrillary acidic protein （GFAP） in the brain tissue. Western blot was employed to determine the protein levels of AQP4， Claudin-5， and zonula occludens-1 （ZO-1） in the hematoma area. ResultsCompared with the sham group， the ICH group showed increases in the mNSS， the cerebral hemorrhage volume， and the escape latency in the Morris water maze test （P<0.01）， decreases in the times of touching the platform and times of entering the quadrant where the platform was located in the Morris water maze test， and reductions in the spontaneous alternation rate in the Y-maze test and the ratio of distance of center travel to total travel distance in the open field test （P<0.01）. Moreover， pathological changes such as cell disarrangement， cell space enlargement， and cell swelling were observed in the ICH group. Immunohistochemistry results showed that the ICH group had higher proportions of AQP4- and GFAP-positive cells and lower proportion of NeuN-positive cells than the sham group （P<0.01）. Compared with the sham group， the ICH group showed an up-regulated protein level of AQP4 and down-regulated protein levels of Claudin-5 and ZO-1 （P<0.01）. Compared with the ICH group， the intervention with Wulingsan decreased the mNSS， the volume of cerebral hemorrhage， and the escape latency in the Morris water maze test （P<0.05， P<0.01）， while increasing the times of touching the platform and times of entering the quadrant where the platform was located in the Morris water maze test， the spontaneous alternation rate in the Y-maze test， and the ratio of distance of center travel to total travel distance in the open field test （P<0.05， P<0.01）. Furthermore， the intervention with Wulingsan alleviated the pathological changes in the brain tissue after ICH， decreased the proportion of AQP4- and GFAP-positive cells （P<0.01）， increased the proportion of NeuN-positive cells （P<0.01）， down-regulated the protein level of AQP4 （P<0.01）， and up-regulated the protein levels of Claudin-5 and ZO-1 （P<0.01）. ConclusionThe intervention with Wulingsan could reduce the neural function score and the cerebral hemorrhage volume， up-regulate the expression of Claudin-5 and ZO-1， and down-regulate the expression of AQP4 to ameliorate the neurological function defect and cerebral edema after ICH， thereby protecting the brain.

Abstract To analyzes the characteristics, problems and enlightenment of physical activity observation tools, so as to provide reference for researchers to quickly and accurately choose appropriate observation tools to evaluate children s and adolescents physical activity. Literature search is conducted in eight databases of Chinese and English, including CNKI, Wanfang, VIP, Web of Science, PubMed, Medline, ERIC, and SPORTDiscus. Ultimately, eight observation tools for assessing physical activity in children and adolescents are included. Through summarization and comparison, it is found that the applications of those tools cover multiple age groups, the observation indicators cover multiple dimensions for each with varying emphases, and the applicable contexts vary in their specific background information, and recording methods tend to be quantitative. However, several issues remain to be addressed in practical applications. First, the observation indicators need to be supplemented and improved; second, physical activity in community environments and academic classrooms requires further attention; third, physical activity intensity needs to be scientifically evaluated; fourth, observation and recording methods need to be integrated and innovated; fifth, the number of observation subjects needs to be expanded. Future research could focus on developing observation tools tailored to the characteristics of Chinese children and adolescents, while drawing on foreign observation tools to comprehensively assess physical activity among children and adolescents.

OBJECTIVE To investigate the monitoring of tacrolimus blood concentration in patients with nephrotic syndrome （NS），and to establish a prediction model for tacrolimus blood concentration. METHODS Data from 509 concentration monitoring sessions of 166 NS patients using tacrolimus were collected from January 1， 2020 to August 31， 2023 in Zhongshan Hospital Affiliated to Xiamen University. The relationship of efficacy and adverse drug reaction（ADR） with blood concentration was analyzed. A multilayer perceptron （MLP） prediction model was established by using the blood concentration monitoring data of 302 times from 109 NS patients with genetic information， and then verified. RESULTS In terms of efficacy， the median blood concentration of tacrolimus in the non-remission group was 2.20 ng/mL， which was significantly lower than that in the partial remission group （4.00 ng/mL， P＜0.001） and the complete remission group （3.60 ng/mL， P＝0.002）. In terms of ADR， the median blood concentration of tacrolimus in the ADR group was 5.01 ng/mL， which was significantly higher than that in the non-ADR group （3.37 ng/mL） （P＝0.001）. According to the subgroup analysis of the receiver operating characteristic curve， when the blood concentration of tacrolimus was ≥6.65 ng/mL， patients were more likely to develop elevated blood creatinine [area under the curve （AUC） was 0.764， P＜0.001）； when the blood concentration of tacrolimus was ≥6.55 ng/mL， patients were more likely to develop blood glucose （AUC＝0.615， P＝ 0.005）. The established MLP prediction model has a loss function of 0.9， with an average absolute error of 0.279 5 ng/mL between the predicted and measured values. The determination coefficient of the validation scatter plot was 0.984， indicating an excellent predictive performance of the model. CONCLUSION Tacrolimus blood concentration has an impact on both efficacy and ADR in NS patients. The use of the MLP model for predicting blood concentration exhibits high accuracy with minimal error between predicted and measured values. The model can be used as an important tool in clinical individualized medication regimens.

Objective To investigate the clinical features of hospitalized children with pertussis.Methods The clinical data of 87 hospitalized children with pertussis admitted to Women and Children's Hospital Affiliated to Xiamen University from January 2019 to December 2022 were retrospectively analyzed.According to the age of the children,they were divided into group A(≤3 months of age,35 cases),group B(4-12 months of age,36 cases)and group C(>12 months of age,16 cases).The clinical features of children at different ages were compared.Results The majority of children with pertussis were<1 year old(81.61%),and August was the month of high incidence.Spastic cough(72.41%)was the main clinical manifestation.Other manifestations included redness or cyanosis,vomiting after coughing,crow echo,etc.There were statistically significant differences in the incidence of spastic cough,redness or cyanosis and the contact history of patients with chronic cough among three groups(P<0.05).There were significant differences in the incidence of pneumonia and the average length of hospital stay among three groups(P<0.05).There was significant difference in C-reactive protein level among three groups(P<0.05).Among 87 children with pertussis,37 cases(42.53%)were infected with other pathogens,among which virus infection was the most common.The treatment is effective with macrolides and compound sulfamethoxazole.Conclusion Pertussis is more common in infants under 1 year of age,and the incidence is high in August.Chronic cough patients with close contact may be the source of infection.Spastic cough is the main clinical symptom of children;the younger,the more common symptoms such as spastic cough,redness and cyanosis,the higher incidence of pneumonia and the longer hospital stay.

ObjectiveTo investigate the mechanism of Zexie Decoction （泽泻汤） in inhibiting neuroinflammation and improving cognitive impairment mediated by high-calorie diet. MethodsTwenty seven C57BL/J mice were randomly divided into control group （n = 9）， model group （n = 9） and Zexie Decoction group （n = 9）. The mice in the model group and the Zexie Decoction group were fed with high-calorie diet to establish the model of cognitive impairment. Meanwhile， the mice in Zexie Decoction group were also fed with 0.36 g/（kg·d）Zexie Decoction， and the mice in the control group and model group were fed with the same volume of normal saline for 8 weeks. The body weight of mice was recorded at the same time every week； after intervention， oral glucose tolerance test （OGTT） and insulin tolerance test（ITT） commenced； the cognitive level of mice was detected by Morris water maze， open field test， new object recognition test and Y maze； magnetic resonance spectroscopy （MRS） was used to detect the expression of N-acetylaspartate （NAA）， choline （CHO）， lactic acid （Lac）， creatine （Cr）， lipid （Lip）， and myoInositol （mI） in left hippocampus， hypothalamus and cortex. Western blotting was used to detect the expression of synaptophysin （SYN）， synaptosome associated protein-25 （SNAP-25）， postsynaptic dense protein-95 （PSD-95）， tumor necrosis factor-α （TNF-α）， nuclear factor kappa B （NF-κB p65） and its phosphorylated form （P-NF-B p65） in mouse brain； Nissl's staining was used to detect the morphological changes of hippocampal neurons. ResultsCompared with the control group， body mass， blood glucose in oral glucose tolerance test， and blood glucose in insulin tolerance test increased in the model group； in the Morris water maze experiment， the total distance travelled and escape latency of the model group mice increased， the time spent in the platform area and the number of times traversing the platform decreased on days 3 and 4； in the open-field experiment， the number of times the model group mice entered the central area， the ratio of the time in the central area to the total time， and the ratio of the distance travelled in the central area to the total distance significantly decreased； in the new object recognition test， the frequency of new object recognition and recognition index were significantly lower in the model group mice； in the Y-maze test， the spontaneous alternation rate of mice in the model group was significantly lower （P＜0.05 or P＜0.01）； in the left hippocampus， hypothalamus， and cortex of mice in the model group， the CHO/Cr， NAA/Cr significantly decreased， and the mI/Cr， Lac/Cr and Lip/Cr significantly increased； SYN/β-actin， SNAP-25/β-actin and PSD-95/β-actin values significantly decreased， and p-NF-κB p65/NF-κB p65 and TNF-α/β-actin values significantly increased in brain tissue （P＜0.05 or P＜0.01）. Compared with the model group， the above indexes of mice in the Zexie Decoction group significantly improved （P＜0.05 or P＜0.01）. The results of Nissl staining showed that compared with the control group， the neurons in the dentate gyrus of the hippocampus in the model group were scattered and sparsely arranged， the density was significantly reduced， the nuclei of the cells had consolidation and shrinkage， the number of Nissl vesicles was reduced， and the staining became lighter； compared with the model group， the density of neurons in the hippocampal dentate gyrus region of the Zexie Decoction group increased， the wrinkling of nuclei improved， the cell gap narrowed， and the arrangement was slightly tight. Concusion The ameliorative effect of Zexie Decoction on cognitive function in mice with high-calorie diet-induced cognitive impairment may relate to the restructuring of glucose metabolism homeostasis， inhibition of neuroinflammation， reduction of neuronal damage， and enhancement of synaptic plasticity.

Objective To observe the safety and effectiveness of ultrasound-guided femoral nerve combined with femoral artery block to reduce tourniquet reaction in patients undergoing knee arthroplasty.Methods 100 patients(18～75 years old,body mass index 18～30 kg/m2)who were classified as grade Ⅰ-Ⅲ according to ASA standard and received unilateral total knee arthroplasty.The patients were randomly divided into two groups,the ultrasound-guided femoral nerve combined with femoral artery block with general anesthesia was utilized in group NA with 50 cases,and femoral nerve block alone with general anesthesia was used in group N with 50 cases.The target nerve block was guided by ultrasound before induction of anesthesia in both two groups,and anesthesia induction was performed after the block effect was etermined.Patients in two groups underwent surgery under general anesthesia of the laryngeal mask,and all patients under went self-controlled intravenous analgesia(PCIA).If a patient had a visual analogue score(VAS)score>5 after surgery,flurbiprofenate 50 mg will be given intravenously as a remedy for anal-gesia.The patients'SBP,DBP and HR were recorded before anesthesia(T1),1 min before tourniquet inflation(T2),15 min after tourniquet inflation(T3),30 min(T4),45 min(T5),and 60 min(T6),the number of cases of tourniquet hypertension occurring in patients intraoperatively and the amount of nicardipine and esmolol were recorded,and the movement and static VAS scores at 2,6,12,and 24 h after surgery were recorded.the postoperative rescue analgesic requirements and the time of getting out of bed were recorded.The incidence of adverse reactions such as nausea,vomiting,deliriumand infection were also recorded.Results Compared with group N,SBP,DBP and HR were significantly lower in group NA at 45 and 60 min after tourniquet inflation,and the incidence of tourniquet hypertension and the amount of nicardipine and esmolol were also significantly lower(P<0.05),and the time of getting out of bed was advanced(P<0.05);the movement and static VAS scores,the time of the first remedial analgesia,and number of times of remedial analgesia,as well as the occurrence of nausea,vomiting,delirium and infection were not statistically significant.Conclusion Ultrasound-guided femoral nerve combined with femoral artery block can be safely and effectively used to reduce the reaction of tourniquet in patients with knee arthroplasty,and can shorten the time of getting out of bed after surgery,contributing to promoting postoperative rehabilitation.

Objective To investigate the application of exoscope in resection of parasagittal meningioma.Methods A retrospective analysis was conducted on 50 patients with parasagittal meningioma undergoing surgical treatment in a same medical group of our neurosurgical department from March 2021 to March 2023.According to their surgical procedures,they were divided into exoscope group(n=22)and microscope group(n=28).The surgical efficacy,surgical complications and surgical experience were compared between the 2 groups and analyzed.Results There were no significant differences between the 2 groups in terms of sex ratio(male/female:10/12 vs 12/16),mean age(50.7±10.2 vs 52.3±11.1 years)and mean tumor size(20.79±25.04 vs 20.60±21.38 cm3).No statistical differences were observed in the duration of operation(217.73±59.66 vs 220.54±56.82 min),intraoperative blood loss(181.82±105.27 vs 189.29±103.06 mL),or total resection rate(90.9％vs 89.3％)between the 2 groups.Postoperative neurological dysfunction,infection rate and other complications also presented no notable differences between them.In the operation of parasagittal meningioma,exoscope can provide a larger view of the parasagittal sinus,such as the subdural border,which is difficult to be exposed by single microscope.Moreover,exoscope presented a higher level of comfort operating and better intraoperative teaching display compared to the surgical microscope.Conclusion For parasagittal meningiomas,exoscope is a safe and effective option,with similar surgical outcomes and postoperative complications as surgical microscope.What's more,exoscope presents more comfortable intraoperative ergonomic posture,higher surgical team participation,and better teaching effect.

Objective To explore the factors influencing the pregnancy rate after fallopian tube recanalization(FTR),and to construct and validate a nomogram prediction model.Methods The clinical data of a total of 322 female patients with tubal obstructive infertility,who received FTR at the Wuhan Municipal Third Hospital of China between January 2018 and December 2022,were retrospectively analyzed.According to whether the female patient had natural pregnancy or not within 12 months after FTR treatment,the female patients were divided into the pregnant group and the non-pregnant group.Logistic regression analysis was used to determine the independent factors influencing pregnancy.The female patients were randomly divided into training group and validation group at 1∶1 ratio.A nomogram model was constructed in the training group,and the predictive efficacy of the model was verified in the validation group by using receiver operating characteristic(ROC)curves,calibration curves and decision curve analysis(DCA).Results The natural pregnancy rate at one year after FTR was 45.34％(146/322).Age＞35 years,primary infertility,duration of infertility＞3 years,distal fallopian tube obstruction,and moderate to severe tubal lesion were the independent risk factors affecting the pregnancy rate after FTR(all P＜0.05).The constructed nomogram model had a good differentiation and calibration ability and it carried a high degree of clinical utility.Conclusion The nomogram model constructed in this study can effectively predict the risk of infertility within one year after FTR treatment,which is helpful for formulating the individualized therapeutic scheme for infertility female patients.

Objective To investigate the efficacy of biportal endoscopic transforaminal lumbar interbody fusion(BE-LIF)in the treatment of lumbar spondylolisthesis complicated with osteoporosis.Methods From June 2021 to June 2022,36 cases of lumbar spondylolisthesis complicated with osteoporosis were treated with BE-LIF,including 9 males and 27 females,aged(65.94±6.83)years(range:51～76 years).All were single segment,and the responsible segment was L3/4 in 4 cases,L4/5 in 26 cases,and L5/S1 in 6 cases.Imagingexamination showed 1 and 2 degree of spondylolisthesis in 28 and 8 cases,and degenerative and ischemic spondylolisthesis in 24 and 12 cases respectively.Preoperative average bone mineral density T value of the lumbar spine was(-3.19±0.82)SD,and T value of the femur(-2.26±0.86)SD.Oswestry disability index(ODI)was used to evaluate lumbar spine function;visual analogue scale(VAS)to evaluate low back pain and leg pain.ODI,VAS of low back and leg pain were recorded respectively before the operation,at discharge and at the last follow-up.MacNab criteria were used to evaluate the surgical efficacy at the last follow-up.The anterior and posterior disc height,segmental lordotic angle and percentage of slip were measured on the lateral lumbar X-ray films before and after the operation.All patients received standard anti-osteoporosis treatment after surgery.Results All patients completed the opera-tion in one stage.The average operation time was(160.97±35.01)min(range:105～245 min),and the average intraoperative blood loss was(72.50±47.53)ml(range:20～150 mL).The mean follow-up time was(15.17±6.53)months(range:6～26 months).There were statistically significant differences in both VAS score of back and leg and ODI score at discharge and last follow-up when compared with those before the surgery(F=107.48,103.66,55.52,P<0.001).Macnab criteria of the last follow-up showed excellent in 21 cases,good in 12 cases,fair in 3 cases,and the excellent and good rate was 91.7%.Radiographic results showed that the height of the ante-rior and posterior disc height,segmental lordotic angle and percentage of slip were all improved immediately after surgery and at the last follow-up when compared with those before operation,but the anterior and posterior disc height,segmental lordotic angle at the last follow-up were decreased comparing with those immediate after the operation;the difference was statistically significant(P<0.001).The fusion rate at the last follow-up was 91.7%(33/36).The complication rate was 13.8%(5/36),including 1 case of intraoperative endplate injury,1 case of nerve root cuff tear,1 case of delayed postoperative wound infection,and 2 cases of posterior cage migration.Conclusion BE-LIF for the treatment of lumbar spondylolisthesis complicated with osteoporosis can achieve better immediate reduction effect,good clinical outcomes and high fusion rate in short-term follow-up,but the anterior and posterior disc height,segmental lordotic angle are partially lost at the last follow-up.There are still complications,and beginners should be cautious when performing the operation.Postoperative standardized anti-osteoporosis treatment is still an important measure to ensure the curative effect of surgery.

Objective·To systematically integrate relevant influencing factors of advanced cancer patients'engagement behavior in advance care planning(ACP).Methods·The systematic search of Chinese and English literature on factors influencing ACP engagement behavior in advanced cancer patients from inception to December 2022 in China National Knowledge Infrastructure(CNKI),Wanfang,China Biomedical Literature Database(Sinomed),PubMed,Cochrane Library,Embase,CINAHL,and PsycINFO was conducted.After the literature quality evaluation,content extraction and summary were conducted by two researchers,and the data of quantitative research and qualitative research were extracted and integrated respectively.The final influencing factors of ACP engagement behavior of advanced cancer patients were obtained.With the help of the theoretical domain,they were mapped to the capability,opportunity,motivation-behavior(COM-B)model step by step.Results·A total of 21 studies were included and 27 factors were summarized,including 9 theoretical domains.Mapping to the COM-B model included 9 capability factors(knowledge of ACP,education level,accurate knowledge of prognosis,knowledge of the time of disease diagnosis,prior experience,subjective life expectancy,age,cancer site,and disease symptom burden),13 opportunity factors(gender,marital status,race/ethnicity,religious belief,dependent children,family economic condition,place of living,housing type,family support,social support,doctor-patient relationship,acculturation,and whether or not to establish a hospice service center)and 5 motivational factors(ACP attitude,ACP belief,ACP motivation,anxiety and depression,and death attitude).Among them,doctor-patient relationship,religious belief,ACP attitude,educational level,marital status,family support,knowledge of ACP,accurate knowledge of prognosis,age,place of living,attitude toward death,prior experience,and race/ethnicity were more influential factors on ACP engagement behavior.Conclusion·Based on the COM-B model,the influencing factors of ACP engagement behavior in advanced cancer patients can be comprehensively summarized.Future studies can use the above factors as an entry point to design continuous,multifaceted,and comprehensive interventions based on the COM-B model to promote the practice of ACP engagement behavior in advanced cancer patients.
