Objective To investigate the effect of behavior change mission mode in traditional Chinese medicine treatment of patients with bone marrow suppression after chemotherapy.Methods Totals of 60 patients after gynecological malignancies who undergone chemotherapy were randomly divided into control and observation groups,both groups used the same kinds of Chinese medicine.Patients in the observation group received health education by behavior change mode,while patients in control group received the general health education.The routine blood test in the two groups were observed and patients were followed up regularly.Results The decrease incidence of WBC in observation group was significantly lower than that in control group (30％ vs 60％),the different were statistical significant (x2 =5.46,P ＜ 0.05).The observation group's bone marrow suppression showed lower incidence than control group with no Ⅳ bone marrow suppression happened.Significant differences were found in the extent of WBC damaged and time required to recover WBC between two groups (P ＜ 0.05).The utilization of leucocyte-stimulating agents,and the use rate of rising WBC medicine in observation group were lower than that in control group [232.5 μg vs 450.0 μg,3.33％ vs 26.67％ ; P ＜0.05)].The time in leukocyte to recovery normal level was more quicker in observation group than control group,the difference was statistical significant (t =5.547,6.364 ; P ＜ 0.05).Conclusions The health education model of behavior change shows the clinical significance in improving the efficacy of traditional Chinese medicine treatment of bone marrow suppression after chemotherapy.

Objective To evaluate the clinical features and the strategy for the diagnosis and treat- ment of bilateral testicular tumor.Methods The clinical data (including the signs and symptoms,imaging studies,tumor markers,treatment modalities and histopatbologic diagnoses) of 10 cases of bilateral testicular tumor from January 1980 to December 2004 were reviewed.Their age ranged from 19 to 58 years(mean,34 years).Of the 10 cases,8 with metachronous and 2 with synchronous testicular tumors were identified.The clinical stages at the primary and secondary tumor diagnosis were:5 cases of stageⅠ,3 of stageⅡ;and 6 cases of stageⅠ,1 of stageⅡ,and 1 of stageⅢ,respectively,in 8 metachronous tumor patients.Two syn- chronous tumor patients were both identified as stageⅠdisease.Histological examination showed the primary tumor (seminoma) in 4 cases and the secondary contralateral tumor (seminoma) in 3.Results Two syn- chronous tumor patients underwent bilateral radical orchiectomy simultaneously,and 8 underwent orchiectomy successively.Retroperitoneal lymph node dissection was performed in 3 cases.Postoperatively,hypogonadism occurred in 10 patients,and 7 of them received androgen replacement therapy.Follow-up ranged from 9 month to 23 years with a mean of 10.5 years.Two patients died of the disease;2 had metastasis (1 of them was alive with metastasis);2 had recurrences and underwent local resection.Conclusions Metachronous bilateral testicular cancers are more common than synchronous bilateral testicular cancers.Seminoma was the most common histopathologic type.Testis-sparing surgery can be performed in selected cases.

OBJECTIVETo investigate the experience on diagnosis and treatment of multiple adrenal aldosterone-producing adenomas (APA).

METHODSEighteen cases of multiple adrenal APA were analyzed retrospectively, which were admitted from October 1992 to April 2006.

RESULTSAdrenalectomy was performed for 4 cases of unilateral synchronous multiple APA, which were discovered with three adenomas by 3D-CT; bilateral tumor resection was performed for 6 cases of bilateral synchronous multiple APA. There were 8 cases of bilateral metachronous multiple APA, including 2 cases of ipsilateral recurrent adrenal APA after adrenal tumor removal, which underwent tumor resection. Another 6 cases were contralateral APA following adrenalectomy due to adrenal APA, and underwent tumor resection. After operation, the adrenal function seemed to be normal, and no recurrence had been found on follow-up.

CONCLUSIONSUnilateral multiple synchronous APA require adrenalectomy. Tumor resection should be performed for bilateral or asynchronous APA, and it is very important to preserve healthy adrenal tissue as much as possible. 3D-CT has much value on diagnosis of small APA, unilateral multiple synchronous APA and ipsilateral recurrent adrenal APA.

Objective:To evaluate the association between preoperative serum β 2-microglobulin (β 2MG) concentrations and postoperative delirium (POD) in elderly patients. Methods:The study selected patients who underwent knee or hip arthroplasty under spinal-epidural anesthesia on an elective basis at Qingdao Municipal Hospital from May 2021 to November 2022. The patients were divided into a POD group and a non-POD group based on the occurrence of POD. The study was conducted as part of the Perioperative Neurocognitive Impairment and Biomarkers Lifestyle Cohort, which was a nested case-control study. The study collected baseline data from two groups of patients and analyzed the differences between them. Logistic regression was used to identify the risk factors for POD. The stability of the regression model was tested using sensitivity analysis. The mediation model was used to examine whether cerebrospinal fluid (CSF) biomarkers mediated the relationship between β 2MG and POD. The receiver operating characteristic curve was drawn and the area under the curve was calculated to evaluate the accuracy of preoperative β 2MG concentrations and CSF biomarker concentration in predicting POD. Results:There were 57 cases in POD group and 449 cases in non-POD group. The results of logistic regression analysis showed that the increased β 2MG and CSF total tau protein (t-tau) concentrations were risk factors for POD, and the increased CSF β-amyloid 42 concentration was a protective factor for POD after adjustment for multiple confounders such as age, gender, education, Mini-Mental State Examination, history of hypertension and infusion volume ( P<0.05). The results of mediation analysis showed that the serum β 2MG′s effect on POD was partly mediated by t-tau (18.1%). The results of the receiver operating characteristic curve showed that the area under the curve of the β 2MG concentration combined with the CSF biomarker concentration was 0.742. Conclusions:Elevated preoperative serum β 2MG concentration is a risk factor for POD in elderly patients, and the relationship may be partly mediated by CSF t-tau.

Objective:To evaluate the relationship between physical activity (PA) and postoperative delirium (POD) in elderly patients undergoing knee or hip arthroplasty.Methods:The study was conducted as part of the Perioperative Neurocognitive Impairment and Biomarkers Lifestyle Cohort, which was a nested case-control study. Medical records from elderly patients undergoing elective knee or hip arthroplasty under spinal-epidural anesthesia at Qingdao Municipal Hospital from August 2022 to August 2023 were collected. The patients were divided into a POD group ( n=89) and a non-POD group ( n=221) based on the occurrence of POD. Peripheral blood samples were collected before surgery, and the cerebrospinal fluid (CSF) 2 ml was extracted after successful puncture under spinal-epidural anesthesia for determination of the concentrations of amyloid-β 42 (Aβ 42), total tau protein (t-tau), and phosphorylated tau protein (p-tau) by enzyme-linked immunosorbent assay. Logistic regression was used to analyze the influencing factors of POD, and the mediation analysis was conducted to examine the mediating role of CSF biomarker in the relationship between PA and POD. Results:Logistic regression analysis showed that the increased concentration of CSF biomarkers Aβ 42 ( OR=0.997, P=0.006), elevated ratio of Aβ 42/t-tau ( OR=0.642, P=0.003), elevated ratio of Aβ 42/p-tau ratio ( OR=0.872, P=0.001) and PA ( OR=0.374, P=0.001) were protective factors for POD, while the elevated concentrations of t-tau ( OR=1.006, P=0.001) and p-tau ( OR=1.030, P=0.011) were risk factors for POD after adjusting for multi-confounders such as hypertension, diabetes, history of drinking, years of education and Mini-Mental State Examination score. The results of the mediation analysis showed that Aβ 42 (20%), t-tau (16%), Aβ 42/t-tau (23%) and Aβ 42/p-tau (28%) played mediating roles in the relationship between PA and POD. Conclusions:PA is a protective factor for POD in elderly patients undergoing knee or hip arthroplasty and CSF biomarkers may play a mediating role in the relationship between PA and POD.

Objective:To evaluate the relationship between the preoperative sleep quality and postoperative delirium (POD) in elderly patients.Methods:Three hundred and eighty-nine patients of either sex, aged 65-90 yr, with American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, who underwent elective knee/hip arthroplasty under combined spinal-epidural anesthesia in Qingdao Municipal Hospital from May 2022 to October 2023, were selected. The Pittsburgh Sleep Quality Index scale was applied at 1 day before surgery to assess the sleep quality within 1 month before surgery. The cerebrospinal fluid (CSF) specimens 2 ml were withdrawn from the subarachnoid space before anesthesia for determination of the concentrations of biomarkers (β-amyloid), total tau protein [t-tau], and phosphorylated tau protein [p-tau]) by enzyme-linked immunosorbent assay. Patients were divided into POD group and non-POD group based on whether delirium occurred within 7 days after surgery. Logistic regression was used to identify the risk factors for POD, and the sensitivity analysis was used to test the stability of the regression models. The mediation model was used to examine whether CSF biomarkers mediated the link between sleep quality and POD. The accuracy of preoperative sleep quality and CSF biomarker concentrations in predicting the occurrence of POD was evaluated by plotting the receiver operating characteristic curve and calculating the area under the curve.Results:Two hundred and seventy-nine patients were finally included, with 33 patients in POD group and 246 patients in non-POD group. The results of logistic regression analysis showed that shorter sleep duration, use of hypnotics, daytime dysfunction within 1 month before surgery, elevated t-tau concentrations in CSF, and elevated p-tau concentrations in CSF were risk factors for POD after adjusting for multiple confounding factors such as age, sex, body mass index, years of education, Mini-Mental State Examination score, and VAS score. The results of mediating effect showed that the effect of use of hypnotics and daytime dysfunction within 1 month before surgery on POD was partially mediated by p-tau concentrations in CSF (>10%). The area under the curve of combination of daytime dysfunction, sleep duration, use of hypnotics within 1 month before surgery, and CSF biomarker concentrations in predicting POD was 0.979.Conclusions:Shortened sleep duration, use of hypnotic, and daytime dysfunction with 1 month before surgery are risk factors for POD in elderly patients, and the association between use of hypnotics and daytime dysfunction and POD is partially mediated by p-tau in CSF.

AIM To explore the clinical effects of Polygonum cuspidatum Sieb.et Zucc.on patients with type 2 diabetes mellitus of Dampness-Heat Pattern.METHODS One hundred and forty patients were randomly assigned into control group(70 cases)for 8-week intervention of conventional treatment,and observation group(70 cases)for 8-week intervention of both P.cuspidatum granules and conventional treatment.The changes in body weight,BMI,blood glucose indices(FBG,2 h PG,HbA1C,GA),blood lipid indices(TC,TG,HDL-C,LDL-C,ApoA-I,ApoB,ApoA,ApoE,sdLDL-C),liver function indices(ALT,AST),fatty liver progression,TyG,HSI,TCM syndrome score and effects were detected.RESULTS The observation group demonstrated higher total effective rates of TCM syndromes than the control group(P＜0.01),along with slighter fatty liver progression(P＜0.01).After the treatment,the observation group displayed decreased body weight,BMI,FBG,GA,TG,ApoE,TyG,HSI,ALT and TCM syndrome score(P＜0.05,P＜0.01),and 2 h PG,TyG,HSI,ALT,TCM syndrome score were lower than those in the control group(P＜0.05,P＜0.01).CONCLUSION For the patients with type 2 diabetes mellitus of Dampness-Heat Pattern,P.cuspidatum can improve glucose and lipid metabolism disorders,which is worthy of clinical popularization and application.

Epilepsy is a brain condition characterized by the recurrence of unprovoked seizures. Recent studies have shown that complement component 3 (C3) aggravate the neuronal injury in epilepsy. And our previous studies revealed that TRPV1 (transient receptor potential vanilloid type 1) is involved in epilepsy. Whether complement C3 regulation of neuronal injury is related to the activation of TRPV1 during epilepsy is not fully understood. We found that in a mouse model of status epilepticus (SE), complement C3 derived from astrocytes was increased and aggravated neuronal injury, and that TRPV1-knockout rescued neurons from the injury induced by complement C3. Circular RNAs are abundant in the brain, and the reduction of circRad52 caused by complement C3 promoted the expression of TRPV1 and exacerbated neuronal injury. Mechanistically, disorders of neuron-glia interaction mediated by the C3-TRPV1 signaling pathway may be important for the induction of neuronal injury. This study provides support for the hypothesis that the C3-TRPV1 pathway is involved in the prevention and treatment of neuronal injury and cognitive disorders.

Objective To explore the predictive value of the model for end-stage liver disease (MELD) score, energy metabolism and serum thyroid hormone levels on the severity and prognosis of patients with liver failure and their correlation. Methods This study collected clinicopathological data from 60 liver failure patients, e.g., end-stage liver disease (MELD) score, energy metabolism, and serum thyroid hormone levels. The χ 2 test was performed to analyze the categorical variables, while the Mann-Whitney U test and independent sample t test were performed to assess the continuous variables between the two groups. Spearman correlation coefficient test was used to evaluate correlation of each index. The receiver operating characteristic (ROC) curve was used to analyze the optimal cut-off points of serum total triiodothyronine (TT3) and free triiodothyronine (FT3) levels in predicting prognosis of the patients. Results The rates of low TT3 and FT3 levels in liver failure patients were 78.2% and 69.1%, respectively, whereas the low TT3 rates were 95.2% and 67.6% and the low FT3 rates were 90.5% and 55.9% in survival and non-survival groups of patients, respectively (both P < 0.05). Moreover, the MELD score was significantly higher in the non-survival patients than in survival patients [26.0(21.0-29.0) vs 21.0 (19.0-24.0), Z =-3.396, P =0.001], while TT3 and FT3 levels were significantly lower in the non-survival patients than in the survival patients [0.69(0.62-0.73) vs 0.83(0.69-0.94) and 2.17(1.99-2.31) vs 2.54(2.12-2.86), respectively; Z =-2.884、-2.876, all P < 0.01]. The MELD score was negatively associated with serum TT3, FT3, and thyroid stimulating hormone (TSH) levels and the respiratory quotient (RQ) ( r =-0.487、-0.329、-0.422、-0.350, all P < 0.01), whereas the RQ was associated with serum TT3 and FT3 levels ( r =0.271、0.265, all P < 0.05). The optimal cutoff values in predicting the severity and survival of patients was 0.75 nmol/L and 2.37pmol/L with the sensitivity values of 67.6% and 64.7% and the specificity of 90.5% and 81.0%, respectively. Conclusion Abnormal thyroid hormone levels and low respiratory quotient could be used to predict the severity and prognosis of patients with liver failure.
