OBJECTIVETo observe the clinical efficacy on migraine treated with acupoint implantation.

METHODSSixty cases of migraine were randomized into a implantation group and an electroacupuncture (EA) group, 30 cases in each one. In the implantation group, implantation was used at Fengchi (GB 20), Taiyang (EX-HN 5), Waiguan (TE 5), Yanglingquan (GB 34), etc., once every 2 weeks, for 4 weeks totally. In the EA group, the acupoints were the same as the implantation group, and EA was applied to Fengchi (GB 20) and Taiyang (EX-HN 5), Yanglingquan (GB 34) and Zusanli (ST 36), once every two days, for 4 weeks totally. The visual analogue scale (VAS) was adopted before and after treatment and the clinical efficacy was compared between the two groups.

RESULTSAfter treatment, VAS score was reduced in the implantation group and the EA group as compared with that before treatment (both P < 0.01). After treatment, VAS score in the implantation group was lower than that in the EA group (P < 0.01). The difference in VAS score before and after treatment in the implantation group was improved apparently as compared with that in the EA group (P < 0.01). The total effective rate in the implantation group was higher than that in the EA group (P < 0.05).

CONCLUSIONThe acupoint implantation reduces VAS score in the patients of migraine and its clinical efficacy is better than that in the EA group. The therapy presents the long-term clinical effect and deserves to be promoted in clinical practice.

OBJECTIVETo explore the relationship between the needling sensation of catgut embedding therapy and the depth of embedded catgut so as to improve the safety of the needle insertion and catgut implantation of the therapy.

METHODSTwenty healthy adults were selected. Under the ultrasound, the structure of the cervical Jiaji (EX-B 2) was observed. In the ultrasound guidance, the catgut was embedded. The two-dimensional imaging method was adopted to observe the anatomic structure and the procedure of needle insertion at the cervical Jiaji (EX-B 2). The high-frequency ultrasound was used to collect the images at Jiaji (EX-B 2) of C5 and determine the depths from the skin surface to the different layers of the point. Additionally, the visual analogue scale (VAS) was adopted to score the needling sensations when the needle inserted at different layers. The persistent sensation duration in the local area was followed continuously.

RESULTSUnder the ultrasound, the anatomic structure and tissue layers of cervical Jiaji (EX-B 2) were displayed clearly. The difference was significant in the average depth from the skin surface to the subcutaneous tissue, trapezius, splenius capitis, semispinalis capitis, semipinalis cervicis, multifidus and vertebral arch between the males and females (all P<0. 01). During the needle insertion, the sensations were apparently different when the implantation went to different layers. The qi arrival presented when the catgut was embedded to the trapezius, splenius capitis, semispinalis capitis, semipinalis cervicis and multifidus. But the distending pain was the most significant when in the myofascial. Commonly, the embedded catgut 2. 5 cm in length may be implanted deeply to the multifidus and the local needling sensation lasted averagely for (72. 0 ± 10. 2) h. Conclusion Under the ultrasound guidance, the depth of embedded catgut is clearly displayed at cervical Jiaji (EX-B 2). The needle insertion and the implanted material are visible, and the relationship between qi arrival and the layer of needle insertion is determined. The accuracy and safety of minimally invasive catgut embedding therapy is improved in the treatment of cervical spondylosis.

Objective To observe the expression level of macrophage stimulating protein (MSP) in acute on-chronic liver.failure (ACLF) patients,and to explore the clinical significance and correlation with different immune regulatory factors.Methods The double antigen sandwich enzyme-linked immunosorbent assay method was used to detect MSP in the peripheral blood of 45 patients who were diagnosed with ACLF and 32 cases of chronic hepatitis B (CHB).The MSP levels were compared among ACLF patients with different outcomes,and the MSP level of healthy person was used as control.Meanwhile,liver function and hepatitis B virus (HBV) load were detected,and the expressions of peripheral blood CD4+ interferon (IFN)γ+ (helper T cell 1 Th1),CD4+ interleukin (IL)-4+ (helper T cell 2,Th2),CD4+IL-17+ (helper T cell 17,Th17) and CD4+ CD25+ Foxp3+ (regular T cell,Treg) were measured by flow cytometry.The comparison of means between two samples was done by t test,and oneway ANOVA and linear correlation analysis were also used.Results The serum MSP levels in ACLF patients,CHB group and healthy control were (1.65±0.46) ng/mL,(1.43±0.32) ng/mL and (1.23±0.21) ng/mL,respectively.The serum MSP level in ACLF patients was significantly higher than both CHB patients (t=2.163,P=0.035) and healthy control (t=4.032,P=0.01).The MSP level in ACLF survival group was statistically higher compared with ACLF death group ([2.29 ± 0.42] ng/mL vs [1.42±0.17] ng/mL,t=1.973,P=0.042).Th2,Th17 cells in ACLF group,CHB group and healthy control group were (1.51±0.27) ％ and (1.94±1.02)％,(0.42±0.08)％ and (0.55±0.36)％,(0.23±0.19) ％ and (0.26±0.19) ％,respectively,which were all significantly different (F=7.759 and 37.229,respectively;both P＜0.01).The MSP level was positively associated with the number of Th2 (r=0.386,P=0.032) and Th17 (r=0.644,P=0.000),and the ratio of Th17/Treg (r =0.605,P=0.000);while it was negatively associated with the number of Th1 (r=-0.212),Treg (r=-0.262) and the ratio of Th1/Th2 (r=-0.394) (all P＞0.05).Conclusion MSP is involved in the progress of ACLF,and it may be associated with clinical outcomes and cellular immune imbalance of ACLF patients.

Background:CT portography(CTP)permits comprehensive evaluation of portal vein and its collateral pathways. It is widely used for assessment of portal hypertension in clinical practice. Aims:To assess the value of CTP in esophagogastric varices in cirrhotic patients. Methods:A retrospective cohort study was performed in 143 cirrhotic patients admitted from Jan. 2013 to Sep. 2015 at the Affiliated Hospital of Qingdao University. All patients fulfilled the inclusion criteria and underwent CTP and gastroscopy within 7 days after admission. According to the occurrence of gastrointestinal bleeding at admission,patients were allocated into two groups:bleeding group( n = 70 ) and non-bleeding group( n = 73 ). Consistency of the results of CTP and gastroscopy was analyzed by kappa coefficient;the accuracy of CTP parameters, including diameters of main portal vein(MPV),splenic vein(SPV)and left gastric vein(LGV)for prediction of variceal bleeding was evaluated by ROC curve. Results:CTP and gastroscopy had a good consistency in typing and grading of esophagogastric varices,with the kappa value of 0. 793 and 0. 775,respectively. The diameters of MPV,SPV and LGV were significantly higher in bleeding group than in non-bleeding group(P < 0. 01),and their area under the ROC curve (AUC)in predicting variceal bleeding was 0. 741,0. 627 and 0. 816,respectively. The accuracy of diameter of LGV was superior to that of MPV and SPV. With the cutoff value of 6. 1 mm,the sensitivity and specificity of diameter of LGV were 65. 71% and 84. 93% ,respectively. With the cutoff value of 16. 3 mm,the sensitivity of diameter of MPV was 75. 71% , which was higher than that of LGV and SPV. Conclusions:CTP can be used in clinical diagnosis of esophagogastric varices in cirrhotic patients,and two CTP parameters,the diameters of LGV and MPV,might be helpful for prediction of variceal bleeding.

Objective To investigate the effects of dihydropteridine reductase (QDPR) on regulating apoptosis induced by plamitic acid(PA). Methods The transfection of HEK293T cells experiment was divided into 3 groups. A group was the control vector group. B group was the control vector group induced by PA. C group was the recombinant plasmid QDPR group induced by PA. First, control vector and recombinant plasmid QDPR was respectively transfected into HEK293T cells. After 24 h, PA with concentration of 0. 5 mmol/L was added into the medium of above cells. The cells of control vector group, the cells of control vector group induced by PA and the cells of recombinant plasmid QDPR group induced by PA were cultured for another 24 hours. At last, cells were harvested to detect tetrahydrobiopterin (BH4) and reactive oxygen species(ROS) generation, Beclin 1, Caspase 3 and Beclin 2 expression. Results ① After transfection, the recombinant plasmid QDPR was successfully constructed and expressed in cells.② There was no significant difference between A group and B group in BH4 generation. Compared with B group, BH4 generation increased in C group (P < 0. 05).③ ROS generation was increased in B group compared with A group, and decreased ROS generation in C group compared with B group (P < 0. 05).④ Western blot analysis revealed that Beclin 1 and Caspase 3 increased (P < 0. 05 ) while Beclin 2 decreased in B group compared with A group (P < 0. 05). Compared to B group, Beclin 1 and Caspase 3 decreased while Beclin 2 increased in C group (P < 0. 05 ). Conclusion QDPR may regulate apoptosis induced by fatty acids by decreasing the generation of ROS and increasing the level of BH4 and the expression of Beclin 2 associated with anti-apoptosis.

Objective:To observe the effect of herbal-partitioned moxibustion (HPM) on pain-related behavior and emotion in a rat model of chronic inflammatory visceral pain, and to investigate the mechanism.
Methods:Twenty-four male Sprague-Dawley (SD) rats were randomly divided into three groups:a normal group, a model group and an HPM group. Except for the normal group, rats in the other two groups were clystered with mixed liquor of Trinitrobenzene Sulfonic Acid (TNBS) and 50%ethanol to induce the chronic inflammatory visceral pain model. After the models were established successfully, rats in the HPM group were treated with HPM at bilateral Tianshu (ST 25) and Qihai (CV 6). Rats in the normal group and the model group were only fixed as those in the HPM group without treatment. Abdominal withdrawal reflex (AWR) score, mechanical withdrawal threshold (MWT) and thermal withdrawal latency (TWL) were adopted to detect the visceral and somatic pain;meanwhile, open field test (OFT) and elevated plus maze test (EPMT) were employed to evaluate pain emotions such as depression and anxiety.
Results:Compared with the normal group, AWR scores of the model group were significantly increased under different stimulus expansion pressure level (P<0.01), MWT and TWL were significantly decreased (P<0.05);in OFT, the values of horizontal activities and vertical activities were significantly decreased (P<0.01);in EPMT, the proportion of the number of entry into the open arms (OE%) and that of residence time in the open arms (OT%) significantly decreased (P<0.01), indicating that the model was successful. Compared with the model group, the AWR score of the HPM group was decreased significantly (P<0.05), MWT and TWL were significantly increased (P<0.05), the values of horizontal activities and vertical activities in the model group were significantly increased (P<0.01);in OFT and EPMT, OE%and OT%were significantly increased (P<0.01).
Conclusion:HPM has analgesic effect on chronic inflammatory visceral pain. It can reduce the visceral and somatic pain in rats and markedly improve the emotions such as anxiety and depression induced by chronic visceral pain.

Objective To investigate the value of tissue motion mitral annular displacement (TMAD) in assessment of left ventricular systolic synchrony in patients with dilated cardiomyopathy (DCM).Methods Thirty-eight DCM patients and 30 healthy subjects were enrolled in this study.The left ventricular end diastolic volume (LVEDV),left ventricular end systolic volume (LVESV),and left ventricular ejection fraction (LVEF) in two groups were investigated using conventional echocardiographyexamination.The time of systolic mitral annular peak displacement (TP) in two groups were measured by the technique of TMAD at six sites (anteroseptal,posteroseptal,anterior,lateral,posterior and inferior).The standard deviation of TP (TP-SD) and the maximal difference of TP (TP-DIF) were calculated.And the correlation between TP-SD and LVEF as well as TP-DIF and LVEF in the DCM group were analyzed.The standard deviation and maximal difference of the time to point with minimal systolic volume of 16 segments (Tmsv16-SD,Tmsv16-DIF) of the DCM group were measured by the technique of real-time three-dimensional echocardiography (RT-3D).And the correlation between Tmsv-16SD and TP-SD as well as Tmsv16-DIF and TP-DIF were analyzed.Results Compared with the healthy subjects,LVESV and LVEDV increased (t=14.023,16.643,P ＜ 0.01) and the LVEF decreased significantly (t=26.112,P ＜ 0.01) in the DCM group.TP,TP-SD and TP-DIF in the DCM group obviously increased (t=7.628,6.869,7.507,6.616,5.631,4.738,7.368,5.777,6.781,P ＜ 0.01).TP-SD and TP-DIF were negatively correlated with LVEF (r=-0.645,-0.513,P ＜ 0.05),while TP-SD and Tmsv1 6-SD,TP-Dif and Tmsv1 6-Dif were positively correlated(r=0.643,P ＜ 0.01;r=0.563,P ＜ 0.05).Conclusions In this study,the TMAD technique was used to measure the time of peak displacement of mitral annulus to evaluate the synchrony of left ventricle movement.It is expected to be a new method in evaluation of the synchrony of left ventricle,which is simple,feasible approach without angle dependence.

Objective To explore the relationship between peripheral blood T lymphocyte subsets and prognosis of patients with advanced non-small cell lung cancer (NSCLC) who received treatment with camrelizumab. Methods We retrospectively collected data from 88 patients with advanced NSCLC who underwent camrelizumab treatment. Peripheral blood lymphocyte subsets were collected from patients before and two months after treatment. Kaplan-Meier curves and Cox regression analysis were employed to investigate the relationship between peripheral blood T lymphocyte subsets and PFS and OS. Results Compared with non-responder group, the baseline peripheral blood CD4+/CD8+ ratio was higher (P=0.038), while the CD8+T lymphocyte percentage was lower (P=0.036) in the responder group. Kaplan-Meier curves showed that a high baseline CD4+/CD8+ ratio was associated with long PFS and OS (P=0.001, P=0.023). Multivariate Cox analysis revealed that the baseline CD4+/CD8+ ratio was a significant predictor for PFS and OS. Additionally, a high post-treatment CD4+/CD8+ ratio and high CD4+T lymphocyte percentage were associated with long PFS (P=0.005, P=0.015), whereas a low post-treatment CD8+T lymphocyte percentage was associated with long PFS and OS (P=0.001, P=0.016). Conclusion The peripheral blood CD4+/CD8+ ratio can serve as a predictive factor for survival of patients with NSCLC treated with camrelizumab.

Objective To investigate the effect of anti-human immunoglobulin M (IgM) on proliferation,apoptosis,cell cycle and tumor formation in human nasopharyngeal carcinoma HNE-1 cell line in vitro and in vivo.Methods After treatment with anti-human IgM antibody,proliferation of HNE-1 cells was observed by cell proliferation inhibition assay,apoptosis and cell cycle of HNE-1 cells were detected by flow cytometry,and apoptotic cells were detected by TUNEL staining.Nude mouse models were constructed,and were injected intraperitoneally with anti-human IgM antibodies (once every 3 days).The growth of transplanted tumor was observed once every 4 days.After the fifth injection,the expression levels of IgM and gp96 protein in transplanted tumor were observed by immunohistochemical method (streptavidin-peroxidase conjugated method,SP).Results MTS assay showed that anti-human IgM antibody can significantly inhibit the proliferation of HNE-1 cells in concentration-and time-dependent manner (P＜0.05).Flow cytometry showed that the anti-human IgM antibody promoted a significant decrease in percentage of cells in G1 phase,a significant increase in percentage of cells in S phase,and a significant increase in apoptotic rate of HNE-1 cells (P＜0.05).TUNEL staining showed that the anti-human IgM antibody promoted apoptosis of HNE-1 cells (P＜0.01).Transplantation tumor experiment showed that anti-human IgM antibody can significantly inhibit the volume and weight of transplanted tumor (P＜0.05).The immunohistochemistry showed that the expression levels of IgM and gp96 proteins in mouse transplanted tumors after intraperitoneal injection with anti-human IgM antibodies were significantly lower than those of the control group (P＜0.05).Conclusion The anti-human IgM anti-body could effectively inhibit the proliferation of HNE-1 cells,promote apoptosis,and arrest cell cycle.Anti-human IgM antibody could also inhibit the growth of transplanted tumor in nude mouse,which might be related to inhibition of the expressions of IgM and gp96 proteins.
