Objective To observe the therapeutic efficacy of acupuncture plus hyperbaric oxygen in treating post-stroke depression. Method Sixty patients with post-stroke depression were randomized into a treatment group of 30 cases and a control group of 30 cases. The treatment group was intervened by acupuncture plus hyperbaric oxygen, while the control group was by Fluoxetine. Before and after intervention, the Hamilton Depression scale (HAMD) was adopted for evaluation, and the efficacies were compared. Result The total effective rate of the treatment group was significantly higher than that of the control (P<0.01);after intervention, the HAMD score of the treatment group was markedly lower than that of the control (P<0.01). Conclusion Acupuncture plus hyperbaric oxygen can obviously improve the depression symptom and promote the recovery of neurologic function in patients with post-stroke depression.

Objective To investigate the curative effect on non-invasive CPAP and SIMV and BiPAP mechanical ventilation in treatment of NRDS. Methods A retrospective study was initiated on clinical data of 162 neonates, who were hospitalized from March 2010 to March 2014 in Jiangmen Central Hospital and underwent the above three modes of non-invasive mechanical ventilation treatment. All cases met the setting standard, and their curative effects were contrasted. Results 53 cases were treated by non-invasive CPAP, 60 cases were operated by non-invasive SIMV, 49 cases were done by non-invasive BiPAP. Among the three groups, the comparison on sex ratio,gestational age of birth and birth weight showed no difference (P > 0.05). The number of effective cases in three groups was 38, 53 and 44 respectively, and the number of invalid cases was 15, 7 and 5 respectively. Among three groups, the curative effect was significant (P > 0.05), curative effect of non-invasive SIMV group showed no difference (P > 0.05) compared with that of non-invasive BiPAP group, curative effect of non-invasive SIMV group and non-invasive BiPAP group was better than that of non-invasive CPAP group (P > 0.05). Conclusion Curative effects of non-invasive SIMV and non-invasive BiPAP for NRDS showed no difference. However, their curative effect is better than that of non-invasive CPAP, which indicates that they can be better choices.

Objective To observe the clinical efficacy of yang-supplementing thread-embedding (acupoint embedded with catgut soaked in Shenfu injection) in treating shoulder-hand syndrome after cerebral stroke. Method Totally 120 patients were randomized into a treatment group and a control group, 60 cases in each group. The treatment group was intervened by acupoint thread-embedding, while the control group was by conventional acupuncture. The changes of symptoms, joint range of motion (ROM), pain, and Fugl-Meyer Assessment (FMA), and general therapeutic efficacy were observed after 30 d treatment. Result The total effective rate was 95.0% in the treatment group versus 85.0% in the control group, and the difference was statistically significant (P<0.05). Conclusion Yang-supplementing thread-embedding and conventional acupuncture both can mitigate pain induced by shoulder-hand syndrome, increase the range of motion, and significantly improve the upper-limb motor function, while the effect of yang-supplementing thread-embedding is superior to that of conventional acupuncture.

Objective To investigate the efficacy of volume target pressure control(VTPC)and synchronized intermittent mandatory ventilation(SIMV)in treating severe neonatal respiratory distress syndrome(NRDS). Methods Fifty - six admitted cases with severe NRDS hospitalized in Jiangmen Central Hospital from October 2012 to March 2015 were randomly divided into 2 groups:28 cases in VTPC group were treated by VTPC and SIMV,and 28 cases in pressure control ventilation(PCV)group were treated by PCV and SIMV. There was no significant difference between 2 groups in terms of gender,gestational age,and birth weight(all P ﹥ 0. 05). Artery blood gas analysis was performed at 6 hours,12 hours,24 hours,and 48 hours respectively after ventilation. The following parameters were observed:the time of invasive mechanical ventilation,duration of oxygen therapy,mortality and the incidence rates of hypocapnia,pneumo-thorax,ventilator associated pneumonia( VAP),grade Ⅲ - Ⅳ periventricular intraventricular hemorrhage( PVH -IVH),periventricular leukomalacia(PVL)and bronchopulmonary dysplasia(BPD). Results No case in 2 groups withdrew from the test. There was no significant difference between 2 groups in terms of the first treatment time and total doses of poractant alfa injection(all P ﹥ 0. 05). The time of invasive mechanical ventilation in VTPC group[(71. 75 ± 9. 82)h]was shorter than that in PVC group[(97. 89 ± 16. 88)h](t = 7. 083,P = 0. 000). Hypocapnia incidence of four blood gas analysis in VTPC group[(19. 64 ± 14. 20)% ]was lower than that in PCV group[(47. 32 ± 18. 43)% ] (t = 6. 294,P = 0. 000). Incidence rates of VAP and PVL in VTPC group were lower than those in PCV group(χ2 =5. 197,P = 0. 023;χ2 = 4. 766,P = 0. 029). However,duration of oxygen therapy,mortality and the incidence rates of pneumothorax,Ⅲ - Ⅳ PVH - IVH and BPD were not significantly different between 2 groups( all P ﹥ 0. 05). Conclusion VTPC + SIMV has a better efficacy than PCV + SIMV in the treatment of NRDS.

Objective To investigate the effects of TLR7 on imiquimod induced apoptosis of THP-1 derived macrophages.Methods Three cell lines ( THP-1 derived macrophages, MDCK cell line and HUVEC cell line) with different capabilities of expressing TLR7 were selected.The survival rates of cells af-ter the treatment with different concentrations of imiquimod were detected by MTT assay.The levels of IL-6 in the supernatants of TLR7 inhibitor chloroquine or TLR7-siRNA treated cells were detected by enzyme-linked immunosorbent assay.The apoptosis of cells was detected by flow cytometry after inhibiting the ex-pression of TLR7.Results Imiquimod induced the apoptosis of THP-1 derived macrophages, MDCK cell lines and HUVEC cell lines.The levels of IL-6 were significantly decreased as the expression of TLR7 was inhibited by treating THP-1 derived macrophages with chloroquine or TLR7-siRNA.Treating THP-1 derived macrophages with chloroquine or TLR7-siRNA did not affect the cell apoptosis induced by imiquimod.Con-clusion Imiquimod could induce the apoptosis of THP-1 derived macrophages through TLR7 independent pathway.

Objective To explore the preventive effect of Fluconazole on invasive fungous infections in premature infants.Methods Two hundred and thirty-four cases of preterm infants hospitalized in Jiangmen Central Hospital from Feb.2008 to Oct.2013 were analyzed by retrospective study.The subjects were divided into 3 groups based on whether Fluconazole was used and it was used orally or intravenously for the prevention of invasive fungous infections in premature infants.The Fluconazole prophylaxis was not given to group A,whereas oral Fluconazole prophylaxis [6 mg/(kg · times),every other day] and intravenous Fluconazole prophylaxis [3 mg/ (kg · times),once every 3 days] were applied in group B and group C.The incidence of invasive fungous infections and the clinical effects of Fluconazole on the 3 groups were evaluated and compared.Results The number of cases analyzed in the study were 53,115 and 66 cases in group A,group B and group C,respectively.There were no significant differences between the 3 groups in terms of gender,gestational age,birth weights,length of hospitalization,intravenous nutrition,and number of peripherally inserted central catheter,antibiotics and invasive mechanical ventilation use days (all P ＞ 0.05).The incidences of invasive fungal infections were 11.32％ (6/53 cases),6.96％ (8/115 cases) and 0 in group A,group B and group C,respectively.The prophylaxis effects between the 3 groups were significantly different (x2 =7.078,P =0.029).Group A and group B were not significantly different (x2 =0.905,P =0.342),but group C was better than group A and group B,and the differences were significant (P =0.007,0.028).Conclusions Prevention of invasive fungous infections by intravenous Fluconazole has good curative effects,and which can be used as the first choice.

Objective:To observe the activation of cerebral regions during swallowing by magnetoencephalography (MEG), and discuss the temporal and spatial characteristics of neural circuit.Methods:Ten healthy subjects were selected, and the magnetic signals of their brains were recorded using 148 channel full head type MEG system in the magnetic shielding room.Data were analyzed using CURRY8 analysis software and the localization algorithm was based on minimum modulus low resolution electromagnetic imaging method (LORETA). Every 300 ms data were set as an independent analysis stage and made the highest position of the cerebral cortex F-distribution values (F-distributed) as the activation area.The activation areas were analyzed during swallowing through time and space location.Results:Paracentral lobule, anterior central gyrus, medulla oblata, posterior central gyrus, inferior frontal gyrus, parietal lobules, angular gyrus, corpus callosum, middle frontal gyrus, cingulate gyrus, orbital gyrus, thalamus, bottom of third ventricle, corona radiata, precuneus, frontal insula, cerebellopontine angle, superior frontal gyrus and basal ganglia area were activated during swallowing, in which the top eight brain regions were paracentral lobule, anterior central gyrus, corpus callosum, posterior central gyrus, superior parietal lobule, middle frontal gyrus, cingulate gyrus, and basal ganglia.When the 10 subjects performed the deglutition, MEG signals of 8 subjects were mainly activated by the left cerebral hemisphere at 0-300 ms, the bilateral cerebral hemisphere or intermediate region at 301-600 ms, and the right cerebral hemisphere at 601-900 ms.MEG signal of 1 subject was activated by the right cerebral hemisphere at 0-300 ms, and the left cerebral hemisphere at 301-600 ms and 601-900 ms.MEG signal of 1 subject was mainly activated by the right cerebral hemisphere at 0-300 ms and 601-900 ms, and in the intermediate region at 301-600 ms.Conclusion:During swallowing the MEG signals appeared left laterality in the early stage and right laterality in the later stage, and showed a close correlation with time.There may be a swallowing neural circuit composed by the central region, corpus callosum, superior parietal lobule, middle frontal gyrus, cingulate gyrus and basal ganglia, in which the central region is the core.

Objective:To study the factors influencing survival after radical resection in patients with intrahepatic cholangiocarcinoma (ICC), and to construct a nomogram on survival prediction.Methods:The clinical data of 139 patients with ICC who underwent radical resection at the People's Hospital of Zhengzhou University from June 2018 to December 2021 were retrospectively analyzed. There are 69 males and 70 females, aged (59.5±10.2) years old. These patients were divided into two groups based on a 3: 1 ratio by using the random number method: the test group ( n=104) and the validation group ( n=35). Data from the test group was used to construct a nomagram and data from the validation group was used to validate the predictive power of the nomagram. Univariate and multivariate Cox regression analyses were used to analyse factors influencing survival on the test group patients and to construct a nomogram. The predictive accuracy of the nomogram was determined by receiver operating characteristic (ROC) curves, concordance index (C-index) and calibration curves. Results:The results of the multivariate regression analysis showed that a combined hemoglobin, albumin, lymphocyte and platelet immunoinflammation (HALP) score <37.1 ( HR=1.784, 95% CI: 1.047-3.040), CA19-9 > 35U/ml ( HR=2.352, 95% CI: 1.139-4.857), poorly differentiated tumor ( HR=2.475, 95% CI: 1.237-4.953) and vascular invasion ( HR=1.897, 95% CI: 1.110-3.244) were independent risk factors that affected prognosis of patients with ICC after radical resection (all P<0.05). The AUCs of the nomogram in the test group in predicting the overall survival at 1, 2 and 3 years of patients with ICC after radical resection were 0.808, 0.853 and 0.859, respectively. There was good consistency between the prediction of the nomogram and actual observation. The predicted C-index of the total survival period of the test group was 0.765 (95% CI: 0.704-0.826), and the C-index of the validation group was 0.759 (95% CI: 0.673-0.845). Conclusion:A HALP score <37.1, CA19-9>35 U/ml, poorly differentiated tumour and vascular invasion were independent risk factors for prognosis of ICC patients after radical resection. The nomogram was established based on the above factors and showed good performance in predicting overall survival after radical resection in patients with ICC.

Objective:To construct a nomogram prediction model for survival after radical surgical resection of intrahepatic cholangiocarcinoma (ICC) based on the albumin-bilirubin index (ALBI), and to evaluate its predictive efficacy.Methods:From January 2016 to January 2020, 170 patients with ICC who underwent radical surgical resection at the People's Hospital of Zhengzhou University were retrospectively analyzed. There were 90 males and 80 females, aged (58.5±10.6) years old. Based on a ratio of 7∶3 by the random number table, the patients were divided into the training set ( n=117) and the internal validation set ( n=53). The training set was used for nomogram model construction, and the validation set was used for model validation and evaluation. Follow up was conducted through outpatient reexamination and telephone contact. The Kaplan-Meier method was used for survival analysis, and a nomogram was drawn based on variables with a P<0.05 in multivariate Cox regression analysis. The predictive strength of the predictive model was evaluated by analyzing the consistency index (C-index), calibration curve, and clinical decision curve of the training and validation sets. Results:Multivariate Cox regression analysis showed that carbohydrate antigen 19-9 (CA19-9) ≥37 U/ml ( HR=1.99, 95% CI: 1.10-3.60, P=0.024), ALBI≥-2.80 ( HR=2.43, 95% CI: 1.40-4.22, P=0.002), vascular tumor thrombus ( HR=2.34, 95% CI: 1.40-3.92, P=0.001), and the 8th edition AJCC N1 staging ( HR=2.18, 95% CI: 1.21-3.95, P=0.010) were independent risk factors affecting postoperative survival of ICC patients after curative resection. The predictive model constructed based on the above variables was then evaluated, and the C-index of the model was 0.76. Calibration curve showed the predicted survival curve of ICC patients at 3 years after surgery based on the model was well-fitted to the 45° diagonal line which represented actual survival. Clinical decision curve analysis showed that the model had a significant positive net benefit in both the training and validation sets. Conclusion:The nomograph model for survival rate after radical resection of ICC was constructed based on four variables: ALBI, CA19-9, vascular tumor thrombus, and AJCC N staging (8th edition) in this study. This model provided a reference for more accurate prognosis evaluation and treatment selection plan for ICC patients.

Objective:To explore the relevant risk factors and prognosis of patients with intrahepatic cholangiocarcinoma (ICC) who experienced recurrence within 6 months after surgeryMethods:This retrospective study included a total of 259 patients with ICC a treated at He'nan Provincial People's Hospital and He'nan Cancer Hospital from Jan 2018 to Jan 2020. The clinical and pathological data ,differences between the group with recurrence within 6 months and the group without recurrence within 6 months were compared using the chi-square test. Logistic regression analysis was used to determine the relevant risk factors for recurrence within 6 months. Kaplan-Meier method was used to construct survival and recurrence curves, and survival rates were calculated.Results:The overall survival and recurrence-free survival of patients in the group with recurrence within 6 months were significantly shorter. CA19-9, tumor longitudinal diameter, microvascular invasion, and neural invasion were identified as independent risk factors for recurrence within 6 months after ICC surgery ( P<0.001). Conclusion:The patient population experiencing recurrence within 6 months after ICC surgery has an extremely poor prognosis and possesses a specific tumor microenvironment. CA19-9, tumor longitudinal diameter, microvascular invasion, and neural invasion were identified as independent risk factors for recurrence within 6 months after ICC surgery.
