Objective To explore the anti-epileptic effect and mechanism of Shenpu Decoction.MethodsThe pilocarpine-induced epilepsy model was adopted. 50 rats were randomly divided into the Shenpu Decoction control group (n=8), blank control group (n=8), Shenpu Decoction plus pilocarpine group (n=8) and pilocarpine-induced epilepsy model group (n=26), the last group was re-divided into the Shenpu Decoction treatment group and model control group. The incidence of convulsion and the content of free amino acids in brain tissues were observed.ResultsThe incidence of convulsion was 0 in the Shenpu Decoction plus pilocarpine group and 88.5% in the pilocarpine-induced epilepsy model group, there was a significant difference between two groups ( P<0.05). The content of glutamic acid in brain tissue of the Shenpu Decoction plus pilocarpine group and pilocarpine-induced epilepsy model group higher than that of the blank control group ( P<0.05～0.01). The content of gamma-aminobutyric acid in brain tissue of the Shenpu Decoction plus pilocarpine group and Shenpu Decoction treatment group was higher than that of the model control group ( P<0.05).ConclusionShenpu Decoction can effectively prevent and terminate the episodes of convulsion.

Objective To determine the central venous pressure (CVP) noninvasively based on hemodynamics principles using ultrasound location of the collapse point of the internal jugular vein.Methods Forty patients were enrolled in this study.The collapse point of the internal jugular vein was located and marked by a linear transducer,the body mark of right atrium was marked on the right lateral wall of the chest.The noninvasive CVP was calculated according to the vertical distance between those two points.The invasive CVP determination by central venous catheter was also carried out on all the patients.Correlation analysis was used to compare the invasive and noninvasive methods.With invasive determination of CVP as the gold standard,the ROC curve of the noninvasive ultrasound method was sketched to explore the optimal cut-off points.Results The correlation analysis reveal high positive correlation between CVPs determined by ultrasound imaging and central venous catheter (r =0.906,P ＜0.01).By the ROC curve test,fluid column height of 10.75 cm by ultrasound method was determined as the cut-off point,with the sensitivity and specificity of diagnosing elevation of CVP being 88.9％ and 93.5 ％ respectively.The corresponding area under the curve was 0.971.Conclusions Ultrasound imaging could be used to determine CVP noninvasively,which would be helpful in diagnosis of the circulating load of patients.

Objective:To explore the related factors of postoperative adjuvant therapy for cervical cancer stagedⅠB1-ⅡA2 [according to 2018 International Federation of Gynecology and Obstetrics (FIGO) staging standard], and to establish a nomogram model to predict the risk of postoperative adjuvant therapy for locally advanced cervical cancer.Methods:A total of 714 patients with cervical squamous cell cancer staged FIGO ⅠB1-ⅡA2 treated by surgery in Anhui Provincial Hospital were selected as the research objects from January 2009 to December 2019, and their clinicopathological data were analyzed. Multiple logistic regression analysis was used to determine the influencing factors, and a nomogram model was established to predict the risk of postoperative adjuvant treatment of cervical cancer. The predictive performance of the model was evaluated with the consistency index (C-index), and the compliance of the model was evaluated with the calibration curve.Results:Univariate analysis suggested that postoperative adjuvant therapy for cervical cancer was associated with gravidity ( χ2=11.506, P=0.001), underlying disease (hypertension or diabetes) ( χ2=7.668, P=0.006), squamous cell cancer antigen (SCC-AG) level ( χ2=19.392, P<0.001), imaging risk factors ( χ2=16.392, P<0.001), FIGO stage ( χ2=25.686, P<0.001), tumor size ( χ2=9.392, P=0.025) and surgical path ( χ2=16.590, P<0.001). Multivariate logistic regression analysis suggested that the number of pregnancy >2 times ( OR=1.951, 95% CI: 1.355-2.808, P<0.001), SCC-Ag ≥1.5 μg/L ( OR=2.021, 95% CI: 1.444-2.829, P<0.001), FIGO stage ⅠB3-ⅡA2 [ⅠB3 ( OR=1.933, 95% CI: 1.139-3.282, P=0.015); ⅡA1 ( OR=2.723, 95% CI: 1.556-4.765, P<0.001); ⅡA2 ( OR=3.159, 95% CI: 1.502-6.646, P=0.002)], with underlying disease (hypertension or diabetes) ( OR=1.867, 95% CI: 1.051-3.318, P=0.033), imaging risk factors ( OR=1.997, 95% CI: 1.127-3.537, P=0.018), without neoadjuvant therapy [preoperative neoadjuvant therapy for 1 cycle ( OR=0.402, 95% CI: 0.207-0.783, P=0.007)] and laparoscopic surgery ( OR=2.177, 95% CI: 1.524-3.112, P<0.001) were independent influencing factors for postoperative adjuvant treatment of cervical cancer. Based on the screened variables, the nomogram model to predict the risk of postoperative adjuvant treatment for cervical cancer has good predictive performance (C-index was 0.702) and compliance. Conclusion:The number of pregnancy >2 times, SCC-Ag ≥1.5 μg/L, FIGO stage ⅠB3-ⅡA2, with underlying disease (hypertension or diabetes), imaging risk factors, without neoadjuvant therapy, and laparoscopic surgery are independent influencing factors for postoperative adjuvant treatment of cervical cancer. A nomogram model has been constructed to predict the risk of postoperative adjuvant therapy for locally advanced cerrical cancer, and it can provide evidence for clinical treatment selection.

Objective To investigate the effect of chemotherapy combined with amino acid on quality of life(QOL)in elderly patients with non-small cell lung cancer(NSCLC). Methods Seventy-four elderly patients with NSCLC were divided randomly into experimental group and control group.The same NP(cisplatin+vinorelbine)chemotherapy was carried out in all the 2 groups for 3 cycles.Except of chemotherapy,experimental group were treated with amino acid 500 ml/d in the same time,while control group recieved chemotherapy only.After 3 monthes,the QOL was analyzed using Chinese Version of European Organization for Researeh and Treatment of Cancer(EORTC)core questionnaire(QLQ-C30)and specific lung cancer module QLQ-LC13,and therapeutic effectiveness was evaluated according to WHO standard as well. Results After chemotherapy,the body function,mood function,social function were better in experimental group than in control group(all P＜0.05),the effective rate was 87.8%,83.8%and 77.0%in experimental group;77.0%,45.9%and 45.9%in control group.Insomnia(8.1%),suppressed appetite(5.4%),weary(47.3%)were less serious in experimental group than in control group(17.6%,17.6%and 59.5%)(all P＜0.05).The primary symptoms were cough,emptysis,thoracalgia and dyspnoea in both 2 groups before chemotherapy.All the symptoms were alleviated after chemotherapy.Some patients have side effects such as tongue pain,alopecie,hand and foot tingle.But the number of patients with tongue pain was less in experimental group(8.3%)than in control group(18.4%).The chemotherapy effect had no difference by the WHO standard. Conclusions The QOL of elderly patients with NSCLC can be improved by chemotherapy combined with amino acid treatment,and the treatment with amino acid 500 ml/d is safety.

Objective To retrospectively analyze the influence of intensity-modulated radiotherapy (IMRT) on tumor regression in primary nasopharyngeal carcinoma (NPC).Methods 272 patients with NPC received radical radiotherapy alone,196 by IMRT with a total treatment time of 6 weeks,and 76 by bilateral field conventional radiotherapy (CRT) with the total treatment timc of 7 weeks.Results By the end of radiotherapy,the primary tumor and neck lymph node residual rates of the IMRT group were 36.7％ and 44.2％,respectively,both significantly higher than those of the GRT group (21.1％ and 26.6％,x2 =6.15,3.99,P ＜ 0.05).Three months after the radiotherapy,residual lesions were observed at the nasopharynx or neck lymph nodes in 12 of the IMRT group,with a residual rate of 6.1％,not significantly different from that of the CRT group (9.2％,7/76).The 12 residual lesions of the IMRT group all vanished completely 4 -9 months after the radiotherapy.Conclusions There is an obvious difference in regressive mode between IMRT and CRT technique in NPC treatment.At the end of IMRT,the tumor residual rate is slightly increased.However,the delivered dose of gross tumor volume (GTV) is sufficient,and the boost dose should not be delivered indiscreetly.
