Objective: To observe the efficacy of warm needling moxibustion plus intra-articular injection of sodium hyaluronate for hip involvement in ankylosing spondylitis (AS). Methods: A total of 60 patients with hip involvement in AS were randomly divided into a control group and an observation group, with 30 cases in each group. The patients in the control group were given an intra-articular injection of sodium hyaluronate, once a week. The patients in the observation group were given additional warm needling moxibustion, once a day, with a 2-day interval after five consecutive days of treatment. After 5 weeks, changes in such indicators as visual analog scale (VAS) score, Harris score, Bath ankylosing spondylitis disease activity index (BASDAI), Bath ankylosing spondylitis functional index (BASFI), serum cartilage oligomeric matrix protein (COMP), interleukin (IL)-17 were observed, and the efficacy was evaluated. Six months after treatment, Bath ankylosing spondylitis radiology index-hip (BASRI-hip) was evaluated. Results: After treatment, the total effective rate in the observation group was higher than that in the control group (P<0.05). After treatment, the VAS scores in both groups were lower than those before treatment (P<0.05), and the score of the observation group was lower than that of the control group (P<0.05). After treatment, the Harris scores of both groups were higher than those before treatment (P<0.05), and the score of the observation group was higher than that of the control group (P<0.05). Six months after treatment, the BASRI-hip score of the control group was higher than that before treatment (P<0.05), while the score of the observation group was not significantly different from that before treatment (P>0.05) and was lower than that of the control group (P<0.05). After treatment, the scores of BASDAI and BASFI of both groups were lower than those before treatment (P<0.05), and the scores of the observation group were lower than those of the control group (P<0.05). After treatment, the levels of serum COMP and IL-17 of both groups were lower than those before treatment (P<0.05), and the levels of the observation group were lower than those of the control group (P<0.05). Conclusion: The efficacy of warm needling moxibustion plus intra-articular injection of sodium hyaluronate for hip involvement in AS is better than the intra-articular injection of sodium hyaluronate alone. This combined approach can alleviate hip pain, improve hip functions, delay the destruction of the hip, prevent AS development, and reduce the levels of serum COMP and IL-17.

Objective To explore the expression of ininor histocompatibility antigen 13 (HM1 3) in gastric carcinoma and the relationship with clinicopathological parameters and prognosis.Methods The expression of HM 13 was detected by immunohistochemistry in a total of 90 pairs of paraffin-embedded gastric cancer tissue specimens and corresponding paraneoplastic tissues.The correlation between clinicopathological parameters and the expression of HM13 in gastric carcinoma were also analyzed.Downstream gene heme oxygenase-1 (HO-1) expression was detected by qRT-PCR after HM13 gene was interfered.Results High expression of HM13 protein was observed in 47％ gastric carcinoma compared with that in 61％ corresponding paraneoplastic tissues (x2 =3.78,P =0.052).HM13 expression has positive correlation with pathological TNM stage (x2 =5.022,P =0.025) and distant metastasis (P =0.033),but not with age (x2 =0.832,P =0.362),gender (x2 =0.779,P =0.378),tumor size (x2 =0.804,P =0.370),tumor differentiation (x2 =0.430,P =0.512),gross types (x2 =2.069,P =0.150),tumor stromal invasion (x2 =0.167,P =0.683) and lymph node status (x2 =0.396,P =0.529).The patients with low HM13 expression had worse overall survival [(OS):(30 ± 5) months vs.(47 ± 5) months,x2 =6.456,P =0.011] and progress free survival [(PFS):(29 ± 5) months vs.(46 ± 5) months,x2 =6.742,P =0.009].Expression of HO-1 was up-regulated after HM13 gene was interfered (0.532±0.013 vs.0.395±0.011,t=13.93,P＜0.05).Conclusion The low expression of HM13 is associated closely with advanced stage and distant metastases of gastric carcinoma.

Objective To explore the effect of chemotherapy on serum IL-6 expression in cancer patients with T2DM. Methods Eighty patients were divided into the malignant tumor group with T 2DM (n=40) and the malignant tumor group without T2DM (n=40).All the patients were given two cycles of chemotherapy .2 ml of fasting venous blood in the morn-ing before and after the day of chemotherapy was collected .Then the serum was separated .Enzyme-linked immunosorbent assay (ELISA)was used to measure the level changes of serum IL-6.20 cases of healthy people were selected for compari-son.Results The expression of serum IL-6 in groups with or without T2DM was significantly higher than in the normal control group before the first cycle of chemotherapy (P<0.05).The expression of serum IL-6 was decreased in the different-cancer group with T2DM after the first cycle of chemotherapy .But the level was increased after the second cycle of chemo-therapy (P<0.05).The expression of serum IL-6 showed a continuous decrease after the first and the second cycle of chemotherapy in the group without T2DM(P<0.05),but there was no significant difference between the two groups (P>0.05).Conclusion The expression level of serum IL-6 declines after the first cycle chemotherapy in the malignant tumor groups with T2DM or without T2DM but rises in the malignant tumor group with T2DM after the second cycle chemotherapy .

Objective To observe the expression of neuropilin-1 (NRP-1) in glioma cells of different grades,and evaluate the application value of a novel molecular probe(USPIO-PEG-tLyP-1)in the grading diagnosis of heterotopic glioma in nude mice by magnetic resonance imaging (MRI).Methods Expression levels of NRP-1 in glioma cell lines of different grades were detected by Western-Blot.USPIO-PEG-tLyP-1 was synthesized by carbon diimine method.The U87-MG tumor-bearing mice model (U87-MG group) and CHG-5 tumor-bearing mice model(CHG-5 group) were established with 10 mice in each group.Six tumorbearing mice with a tumor volume about 0.6 cm3 were selected from each group,and they were given with 2mg/kg molecular probes via tail vein respectively and was detected by MRI at 0 h,6 h,12 h and 24 h,then R2 values were calculated.After the imaging,tumor-bearing mice were sacrificed,and tumor tissue sections were made.The iron particles in the sections was detected by Prussian blue staining.The binding ability of molecular probes and tumor tissues in the two groups was compared.Results The expression of NRP-1 in U87-MG and CHG-5 cell lines was significantly higher than that in HA.In addition,the expression of NRP-1 in U87-MG was higher than that in CHG-5 cell(P＜0.01).MRI results showed that R2 values of tumor tissues in the two groups were compared,and the difference was not statistically significant before the injection of molecular probe(U87-MG group(10.35±0.52)vs CHG-5 group(9.86±0.43),t=1.779,P=0.106).The R2 value of tumor tissue in the U87-MG group was higher than that in the CHG-5 group after the injection of molecular probe (6 h:U87-MG group (11.63±0.85)vs CHG-5 group (10.51 ±0.49),t=2.796,P=0.019;12h:U87-MG group(14.23±0.68)vs CHG-5 group(12.29±0.28),t=6.462,P=0.000;24 h:U87-MG group (13.36±0.92) vs CHG-5 group(11.32±0.64),t=4.459,P=0.001).The results of Prussian blue staining showed that there were significantly more blue staining particles in tumor tissues of the U87-MG group than that of the CHG-5 group,and the difference was statistically significant(P＜0.01).Conclusion The NRP-1 targeted molecular probe can be used for grading diagnosis of high and low grade heterotopic brain glioma in nude mice.

Objective To investigate the efficacy and value of intra-operative neuromonitoring (IONM) in preventing,identifying and repairing recurrent laryngeal nerve injury (RLNI) during thyroidectomy and parathyroidectomy.Methods Data were collected from a series (n =351) of patients operated in our department between Jan 2015 and Dec 2017.Results With IONM navigation a total of 460 recurrent laryngeal nerves were identified during surgery.Anatomic variations were found in 6 cases,3 were non-recurrent laryngeal nerve.Others were morphological branching variation.There were 4 cases of temporary RLNI,all were unilateral.Total temporary RLNI rate was 1.1％.All 4 cases recovered completely in 3 months after surgery.Complete transection injury of RLN were found in 2 cases,one underwent immediate nerve anastomosis,with the voice significantly improved in 6 months.The total permanent RLNI rate was 0.5％.There was no hoarseness after operation in patients with normal IONM signal.The incidence of vocal cord paralysis was 57.14％ in patients with loss of IONM signal but normal appearance of RLN.Use of IONM did not increase operation time.Conclusions IONM had significant advantages in recognition of RLN,repair of intraoperative RLNI and prediction of postoperative voice condition,which could improve the safety of surgery.

Objective Energy based surgical devices such as high frequency electrotome,Harmonic scalpel and LigaSure are widely used in thyroid operations.This study is to demonstrate the difference of tissue thermal damage among different surgical instruments.Methods 12 beagle dogs were randomly divided into 3 groups,electrotome 15 W groups (group A),three-speed Harmonic scalpel (group B) and LigaSure middle gear group (group C).Patients of each group received energy instruments operating on their thyroid tissue which mimics traditional thyroidectomy.The temperatures of gland tissue during procedures were monitored by infrared thermal imager,and the operated thyroid tissues were histologically analyzed.Results The highest temperature was (83.9±8.2)℃ in the electrotome group,(70.7±7.5)℃ in three-speed Harmonic scalpel group,and (56.6±5.7)℃ in LigaSure group.The highest temperature among the three groups was statistically significant.The electrotome (15 W) caused more serious thermal damage to thyroid tissues than that caused by either the Harmonic scalpel or LigaSure (thermal damaged depth:(0.96±0.07) mm vs (0.74±0.07) mm,P＜0.01;(0.96±0.07) mm vs (0.72± 0.11) mm,P＜0.01).Nevertheless,the thermal damage had no significant differences between the Harmonic scalpel and LigaSure group (P=0.845).The thermal damage caused by the 15 W electrotome was significantly larger than that in the other two groups,and the difference had statistical significance (P＜0.01).Conclusion Compared to the high frequency electrotome,Harmonic scalpel and LigaSure lead less tissue thermal damage during thyroid surgeries,owing to less heat production.In that way,Harmonic scalpel and LigaSure are superior to electrotome in terms of safety.

Objective:To investigate the expression of CD157 and its significance in colorectal cancer.Methods:The expression of CD157 was detected in 50 cases of colorectal cancer tissues and corresponding adjacent normal colorectal tissues by immunohistochemistry. The correlation between the expression of CD157 and clinicopathological parameters and prognosis was analyzed statistically.Results:Higher expression of CD157 protein was observed in colorectal cancer than that in normal colorectal tissues (72% vs. 20%, χ 2=25.09, P<0.01). Moreover, High expression of CD157 was correlated with the tumor size (χ 2=7.368, P=0.007), TNM stage (χ 2=9.223, P=0.002), the depth of tumor infiltration (χ 2=4.158, P=0.041), distant metastasis (χ 2=5.521, P=0.019), vascular invasion (χ 2=6.307, P=0.012) and microsatellite instability (χ 2=4.778, P=0.029), but not with gender, age, histology type, location, differentiation grade, lymph node metastasis, nerve infiltration or Kras mutation (all P>0.05 respectively). Patients with low expression of CD157 had longer survival (45±4 )months than those with high expression (30±3)months (χ 2=5.234, P=0.022). Conclusions:High expression of CD157 in colorectal cancer tissue is related to poor survival of postoperative patients.

Objective:To explore the expression of vasohibin-1 (VASH1) and vascular endothelial growth factor A (VEGF-A) and clinical significance of VASH1 in gastric carcinoma.Methods:The expression of VASH1 and VEGF-A were detected by immunohistochemistry in formalin-fixed and paraffin-embedded sections in 56 pairs of gastric cancer and corresponding paraneoplastic tissue specimens. The correlation between the expression of VASH1, VEGF-A, clinicopathological parameters and prognosis were analyzed.Results:VASH1 and VEGF-A expression was significantly higher in gastric cancer tissues than normal paraneoplastic tissues. VASH1 and VEGF-A protein were expressed in 79% and 82% of gastric cancer tissues, respectively. A positive correlation was found between Vasohibin-1 and VEGF-A expression in gastric cancer tissues. VASH1 expression has significant positive correlation with TNM stage, tumor stromal invasion, tumor gross types and distant metastasis. Patients with high VASH1 expression had significantly worse overall survival (OS) and progression-free survival (PFS) than those with low VASH1 expression.Conclusion:VASH1 might be a clinically relevant predictor of patients in gastric cancer.

Posttraumatic stress disorder (PTSD), the most common mental illness after patients suffer physically or emotionally from traumatic events, can cause persistently strong, painful and terrible avoidance symptoms, emotional and cognitive changes, causing psychologically strong stimulation and heavy burden to patients and even leading to some extreme behavioral reactions. Traumatic brain injury (TBI) is an important factor in the occurrence of PTSD, both of which shares many similar pathological overlaps, and may coexist and interact with each other. The hippocampus and amygdala play a central role in the pathogenesis of PTSD, but the specific cellular and molecular and neural circuit mechanisms are still unclear. About two-thirds of the patients still meet the diagnostic criteria for PTSD after psychotherapy. However, the current treatment methods are complicated and not unified, and patients treated with medications may have adverse drug reactions, poor treatment outcomes and recurrence. Therefore, it is of great significance to further clarify the occurrence and development of PTSD in TBI patients. The authors reviewed the research progress of the pathogenesis and treatment of PTSD in TBI patients, so as to provide reference for the related research and treatment of PTSD in TBI patients.

Craniocerebral injury with seawater immersion is a special kind of compound injury, with low temperature, high permeability, high alkali, high salt content, and bacterial infection being the main causes. The injury is also characterized with complex damage mechanisms, difficulty to treat, and poor prognosis. At present, the damage mechanisms of craniocerebral injury with seawater immersion are mainly studied by establishing the experimental animal models at the levels of tissue, cell, organelle, molecule, etc. However, the craniocerebral injury with seawater immersion is more complex than the simple onshore craniocerebral injury, therefore, a stable disease model is not easy to construct. Most researches on the specific injury mechanisms are relatively single and one-sided, with many different views in existence, and the damage mechanisms of craniocerebral injury with seawater immersion have hitherto not been clear. The authors reviewed the research progress in the damage mechanisms of craniocerebral injury with seawater immersion, in order to promote the in-depth study of the mechanism of craniocerebral injury with seawater immersion and provide reference for its clinical treatment.
