Objective To investigate the predictive value of serum vasoactive intestinal peptide(VIP)and 5-hydroxytryptamine(5-HT)levels on the outcome of spinal cord electrical stimulation(SCS)in patients with postherpetic neuralgia(PHN).Methods A total of 96 PHN patients who received SCS treatment in Ziy-ang Central Hospital from January 2022 to December 2023 were selected.According to the disease outcomes of all PHN patients after 6 months of treatment,a good group(n=71)and a poor group(n=25)were set up.The clinical data of the two groups were collected and the serum VIP and 5-HT levels were detected in all pa-tients before treatment.The predictive value of serum VIP and 5-HT on disease outcome after SCS treatment in PHN patients was evaluated by receiver operating characteristic(ROC)curve,and the influencing factors of disease outcome after SCS treatment in PHN patients was explored by multivariate Logistic steppe gression a-nalysis.Results The levels of serum VIP and 5-HT in poor group were higher than those in good group(P＜0.05).The area under the curve(AUC)of serum VIP and 5-HT for predicting the disease outcome of PHN patients after SCS treatment were 0.829(95％CI:0.779-0.874)and 0.743(95％CI:0.693-0.793),respec-tively,and the AUC of combined prediction was 0.941(0.891-0.986).There were no significant differences in age,gender,body moss index,education,location of onset,hypertension and drinking history between the two groups(P＞0.05).The time of initial hospital admission in the poor group was longer than that in the good group,skin rash area in the poor group was larger than that in the good group,and diabetes mellitus and smoking history in the poor group were higher than those in the good group(P＜0.05).The time of admis-sion for initial treatment＞3 d(OR=2.188,95％CI:1.383-3.461),skin rash area＞10 cm2(OR=2.018,95％CI:1.283-3.173),diabetes mellitus(OR=2.264,95％CI:1.379-3.717),serum VIP level ≥41.78 ng/L(OR=3.022,95％CI:1.685-5.420),serum 5-HT level ≥99.27 ng/mL(OR=3.579,95％CI:1.885-6.793)were the influencing factors of disease outcome after SCS treatment in PHN patients(P＜0.05).Con-clusion The elevated levels of serum VIP and 5-HT before treatment are associated with poor outcomes after SCS in patients with PHN,and could be used as potential markers to predict the outcomes of SCS in patients with PHN.

Objective: To construct nomogram to predict the risk of bone metastasis in patients with non-small cell lung cancer(NSCLC). Methods: The clinical data of NSCLC patients diagnosed in the hospital were retrospectively analyzed, including the occurrence of bone metastasis, age, gender, pathological type, smoking status, PS score, TN stage, metastasis of other sites before bone metastasis, carcinoembryonic antigen(CEA) level, alpha fetoprotein(AFP) level, serum calcium(Ca2+), serum phosphorus(P), alkaline phosphatase(ALP) level, which were determined by univariate and multivariate logistic regression analysis. Receiver operating characteristic curve(ROC) and decision curve analysis were used, DCA was used to verify the accuracy and clinical benefit of the model, and nomogram was used to visualize the model. Results: Area under the ROC curve(AUC) showed that in the modeling group(n=138) and the validation group(n=92), the AUC value predicted by combined indicators(age, gender, pathological type, CEA, ALP)(modeling group=0.792, validation group=0.629) was higher than that predicted by single indicator. Conclusion The prediction model constructed in this study has good effect and can provide reference for clinical screening of high-risk patients with bone metastasis of NSCLC.

Objective:This study aims to examine the incidence and risk factors of violent behaviors in community-dwelling unmedicated patients with severe mental disorders in Shenzhen.Methods:The baseline and follow-up data of unmedicated patients with severe mental disorders were collected from the Information Management System of Mental Health Prevention and Control in Shenzhen. The incidence of violent behaviors in unmedicated patients was described. The influencing factors of violent behaviors were analyzed using logistic regression model.Results:A total of 3 163 patients were included. The incidence of violent behaviors was 9.1% (288/3 163) in 2019. Multivariate logistic regression analysis showed that having an acute illness onset ( OR=1.589, 95 %CI 1.181-2.139) was the risk factor of violent behaviors, while having cohabitants ( OR=0.596, 95 %CI 0.410-0.867), being diagnosed as mental retardation comorbid with psychotic disorders ( OR=0.432, 95 %CI 0.199-0.938), having application for carers allowances ( OR=0.440, 95 %CI 0.319-0.606), and participating in family doctor services ( OR=0.642, 95 %CI 0.492-0.838) and community face-to-face interviews during 2019 ( OR (1-2 times vs. 0 times)=0.633, 95 %CI 0.466-0.861; OR (3-4 times vs. 0 times)=0.546, 95 %CI 0.368-0.811) were the protective factors. Conclusions:The incidence of violent behaviors is high in unmedicated patients with severe mental disorders with acute illness onset. The improvement of comprehensive level of community mental health services and the development of targeted intervention measures would help to reduce the occurrence of violent behaviors among unmedicated patients with severe mental disorders in the community.

Outbreaks of pseudorabies (PR) have occurred in southern China since late 2011, resulting in significant economic impacts on the swine industry. To identify the cause of PR outbreaks, especially among vaccinated pigs, 11 pseudorabies virus (PRV) field strains were isolated from Guangdong province during 2013–2014. Their major viral genes (gE, TK, gI, PK, gD, 11K, and 28K) were analyzed in this study. Insertions or deletions were observed in gD, gE, gI and PK genes compared with other PRV isolates from all over the world. Furthermore, sequence alignment showed that insertions in gD and gE were unique molecular characteristics of the new prevalent PRV strains in China. Phylogenetic analysis showed that our isolates were clustered in an independent branch together with other strains isolated from China in recent years, and that they showed a closer genetic relationship with earlier isolates from Asia. Our results suggest that these isolates are novel PRV variants with unique molecular signatures.

Objective To explore the effect of surface electromyography biofeedback combined with the routine comprehensive rehabilitation treatment on walking ability of stroke patients with hemiplegia. Methods 80 stroke patients with hemiplegia were randomly divided into control group (n=40) and treatment group (n=40). All the patients received routine comprehensive rehabilitation treatment. The treatment group received electromyography biofeedback electrostimulation in addition. Fugl-Meyer Assessment was used to assess motor and balance function; active range of movement of ankle joint, the integrated electromyogram (iEMG) of isometric contraction of anterior tibialis muscle under maximum ankle dorsiflexion and Holden walking function were determined before and 8 weeks after treatment. Results 8 weeks after treatment, the scores of motor and balance function, the active range of movement of ankle, the iEMG, and Holden walking function significantly improved in both groups (P<0.001), and improved more in the treatment group than in the control group (P<0.05).Conclusion The electromyography biofeedback combined with routine comprehensive rehabilitation treatment can improve ankle motion control ability and walking ability of stroke patients with hemiplegia.

Purpose To explore CT manifestations of thyroid carcinoma and its correlation with neck lymph node metastasis. Materials and Methods CT findings of 165 patients with thyroid carcinoma confirmed by surgical pathology were studied, including number, shape, size, calcium, necrosis, surrounding invasion and enhancement of substantial part, and its correlation with neck lymph node metastasis was also analyzed. Results 107 out of 165 patients (64.85%) suffered from neck lymph node metastasis. Different tumor number, calcium and necrosis were not associated with the rate of neck lymph node metastasis (χ2=0.009, 2.606, 1.522;P>0.05);tumor shape, size, surrounding invasion and enhancement were significantly different from the rate (χ2=26.510, 75.995, 68.922, 20.819;P<0.05). Patients age, tumor shape, size, enhancement and surrounding invasion were positively correlated with lymph node metastasis (r=0.124, 0.243, 0.276, 0.287, 0.395;P<0.05);the sequence of correlation was as follows:surrounding invasion>enh ancement>shape>size>age. However, patients gender, tumor number, calcium and necrosis showed on correlation (r=0.074, 0.126, 0.005, 0.121;P>0.05). Conclusion Lymph node metastasis is mainly associated with factors like age, tumor shape, size, enhancement and surrounding invasion. It is advisable that patients with high risk rate may consider selective cervical lymph node dissection.

ObjectiveTo analyze the short-term efficacy of mastoscopic axillary lymph node dissection for the patients with early breast cancer who undergo breast-conserving surgery.MethodsThirty patients who met the standard of breast-conserving surgery were divided into two groups by random digits table with 15 cases each.All of these patients underwent breast-conserving surgery,then study group underwent mastoscopic axillary lymph node dissection while control group underwent open technique.The short-term efficacy was observed and compared between two groups.ResultsThe operation time in study group [(88.0 ± 18.0) min] was longer than those in control group [(68.0 ± 12.5) min] with significant difference (P =0.001 ).The incidence of upper extremity edema [ 6.7％ ( 1/15 ) ] and intercostobrachial nerve injury (0) in study group was lower than those in control group[60.0％(9/15),40.0％(6/15) ] with significant difference(P =0.002,0.022).There was no significant difference in blood loss,nodes harvest,total drainage volume and residual cancer cells between two groups [ ( 18.0 ± 12.2) ml vs.(21.3 ± 9.0) ml; 14.6 ±5.0 vs.16.4 ±3.6; (87.9 ±25.1) ml vs.(86.3 ±13.8) ml;6.7％(1/15) vs.13.3％(2/15)] (P ＞0.05).ConclusionsMastoscopic axillary lymph node dissection has the similar nodes harvest with open technique.The incidence of adverse reaction is lower,and the short-term effect is better.
