OBJECTIVE: To observe the clinical effect of lever positioning manipulation for the treatment of lumbar disc herniation and its effect on Cobb angle. METHODS: From December 2017 to November 2018, 67 patients with lumbar disc herniation were included in the study. The patients were randomly divided into treatment group and control group by digital table method. There were 34 cases in the treatment group, including 20 males and 14 females, with an average age of (36.09±8.26) years old and a course of (13.79±15.50) months. Treatment group was treated with lever positioning manipulation. There were 33 cases in the control group, including 18 males and 15 females, with an average age of(36.48±7.81) years old and a course of (12.82±15.68) months. Control group was treated with lumbar slanting manipulation. Two groups were treated 3 times a week, once every other day, 6 times for a course of treatment, after 2 courses of treatment, the changes of Cobb angle before and after treatment were compared between two groups by imaging. The symptoms and signs were scored with reference to clinical evaluation standard;overall efficacy was evaluated with reference to "Diagnostic Efficacy Criteria of Traditional Chinese Medicine Syndrome" issued by the State Administration of Traditional Chinese Medicine for lumbar disc herniation. RESULTS: One patient in each group dropped out. The symptom and sign scores of treatment group and control group before treatment were 18.56± 4.81, 18.61±3.72, while after treatment were 9.41±5.19, 13.55±3.68;treatment group was significantly lower than control group after treatment ( CONCLUSION Both the lever positioning manipulation and the lumbar slanting manipulation methods are effective for the treatment of lumbar disc herniation, but clinical effect of lever positioning method on lumbar disc herniation is more significant, and the effect on Cobb angle is more obvious. It is worthy of promotion.

OBJECTIVE: To observe the analgesic effect of lever positioning manipulation combined with pulsed electric field on patients with lumbar disc herniation and the influence on serum IL-1β and TNF-α. METHODS: From January 2018 to March 2019, 58 patients with lumbar disc herniation were included in the study, which were randomly divided into observation group and control group by digital table method. Observation group of 29 cases, including 16 males and 13 females, aged (38.03±11.29) years old, were treated with lever positioning manipulation combined with pulsed electric field. The 29 cases in control group, including 17 males and 12 females, aged (38.21±9.16) years old, were treated with pulsed electric field. Both groups of patients were treated 3 times a week, once every other day, 3 times as a course of treatment. After 2 courses of treatment, the two groups of patients were scored before and after treatment by the numeric rating scales (NRS);at the same time, the serum levels of IL-1β and TNF-α were measured before and after treatment. RESULTS: The NRS scores of observation group and control group were 4.21±1.76, 4.66±1.61 before treatment, and 1.28±0.84, 2.10±1.35 after treatment, respectively. The NRS scores of the observation group after treatment was significantly lower than that of the control group ( CONCLUSION The lever positioning manipulation combined with pulsed electric field has a good analgesic effect on patients with lumbar disc herniation, and it has a significant impact on the patient's serum IL-1β and TNF-α concentration, which can be used as a clinical guide. However, the synergistic effect of lever positioning technique combined with pulsed electric field and guidelines for clinical treatment need further research.

Objective To investigate the risk of Anisakis infections among high-risk populations along the coastal areas of Jiangsu Province, so as to develop the strategy for the prevention and control of anisakiasis in the province. Methods Three counties along the coastal areas of Jiangsu Province were selected as the study sites in 2018, including Rudong County in Nantong City, Haizhou District in Lianyungang City and Dongtai City in Yancheng City. The knowledge, attitude and practice (KAP) of anisakiasis prevention and control, and the prevalence of serum specific IgG antibody against Anisakis were investigated among high-risk populations among these three study sites, including fishermen, fish seller and people who liked eating fresh and live marine fish. Factors affecting the prevalence of the specific IgG antibody against Anisakis were identified using a multiple logistic regression model. In addition, Anisakis larvae infections were detected in fresh and live marine fish samples collected from local markets, and the prevalence and intensity of Anisakis infections were estimated. Results A total of 625 high-risk populations were investigated, including 349 men (55.8%). Only 13.0% of the subjects heard about anisakiasis, and a low awareness rate of anisakiasis prevention and control knowledge was seen among these three types of high-risk populations. There were 21.6% of the subjects eating raw or half-cooked marine fish, 5.8% eating undercooked marine fish, 3.2% presenting vomiting, nausea and diarrhea after eating marine fish, 5.1% developing systemic allergic symptoms, and 65.6% using the same chopping board for raw and cooked food. The sero-prevalence of the anti-Anisakis IgG antibody was 7.0% among the study subjects. Multiple logistic regression analysis identified education level [OR = 0.687, 95% CI (0.478, 0.987)] and development of systemic allergic symptoms [OR = 4.641, 95% CI(1.411, 15.268)]as factors affecting the positive anti-Anisakis IgG antibody among the study subjects. Among 494 fresh and live marine fish detected, the prevalence and intensity of Anisakis larvae infection was 64.0% and 8.1 larvae per fish, with high prevalence seen in Trichiurus haumela and Pneumatophorus japonicas. Conclusions The awareness of anisakiasis prevention and control knowledge is low among the high-risk populations living along the coastal areas of Jiangsu Province, and there are high-risk behaviors, such as eating raw or half-cooked food, using the same chopping board for raw and cooked food. In addition, the prevalence of Anisakis infections is high in the marine fish in these areas. Therefore, the health education and health promotion for anisakiasis prevention and control should be intensified.

Background: Malignant pleural effusion (MPE) is a complicated condition of patients with advanced tumors. Further dissecting the microenvironment of infiltrated immune cells and malignant cells are warranted to understand the immune-evasion mechanisms of tumor development and progression. Methods: The possible involvement of microRNAs (miRNAs) in malignant pleural fluid was investigated using small RNA sequencing. Regulatory T cell (Treg) markers (CD4, CD25, forkhead box P3), and Helios (also known as IKAROS Family Zinc Finger 2 [IKZF2]) were detected using flow cytometry. The expression levels of IKZF2 and miR-4772-3p were measured using quantitative real-time reverse transcription polymerase chain reaction. The interaction between miR-4772-3p and Helios was determined using dual-luciferase reporter assays. The effects of miR-4772-3p on Helios expression were evaluated using an in vitro system. Correlation assays between miR-4772-3p and functional molecules of Tregs were performed. Results: Compared with non-malignant controls, patients with non-small cell lung cancer had an increased Tregs frequency with Helios expression in the MPE and peripheral blood mononuclear cells. The verified downregulation of miR-4772-3p was inversely related to the Helios⁺ Tregs frequency and Helios expression in the MPE. Overexpression of miR-4772-3p could inhibit Helios expression in in vitro experiments. However, ectopic expression of Helios in induced Tregs reversed the effects induced by miR-4772-3p overexpression. Additionally, miR-4772-3p could regulate Helios expression by directly targeting IKZF2 mRNA. Conclusion Downregulation of miR-4772-3p, by targeting Helios, contributes to enhanced Tregs activities in the MPE microenvironment.

Objective To verify the change of the anxiety and depression of patients anteriorposterior treatment at paraurethral duct dilitation after gonococcal infection of paraurethral duct.Methods Twenty-eight patients of paraurethral duct dilatation after male gonococcal infection of paraurethral duct were enrolled,and the patients were treated in the Department of Dermatology and Venerology,the First People's Hospital of Changshu City.The anxiety and depression of patients anteriorposterior treatment were assessed and compared with Hamilton depression scale and Hamilton anxiety scale.Results The total scores of Hamilton depression scale and Hamilton anxiety scale before treatment were positively correlated with course of disease (r =0.481,P =0.0095;r =0.549,P =0.0025).The total scores of Hamilton depression and anxiety before treatment were from 1 to 31 (18.9±7.5) and from 4 to 30 (14.9±6.8).The symptoms of depression and anxiety appeared in 11 patients and 15 patients respectively.The total scores of Hamilton depression andanxiety after treatment were from 0 to 8 (4.3±1.7) and from 0 to 8 (3.3±1.7).There was no symptom of depression and anxiety.The difference of the total score of Hamilton depression and anxiety before and after treatment had statistical significance (t =12.270,P＜0.001,t =10.626,P＜0.001).The difference of positive rate of depressive and anxious symptom before and after treatment had statistical significance too (x2 =9.05,P=0.003;x2 =13.06,P=0.000).Conclusions The sequelae of gonococcal paraurethral duct infection in male paraurethral duct dilatation can result in the anxiety and depression of patients,which should be treated.Effective therapy can relieve or cure the anxiety and depression of patients without the assistance of psychotropic drugs.

Objective The role and action mechanisms of NADH dehydrogenase 1 alpha subcomplex 4 (NDUFA4) in the development of human colorectal cancer (CRC) are not yet clarified. This article aims to study the effect of overexpressed NDUFA4 on the epithelial-mesenchymal transition (EMT) of human CRC cells. Methods The recombinant plasmid NDUFA4 (p-NDUFA4) and control plasmid (p-Cont) were transiently transfected into human CRC HCT116 cells. The expression of NDUFA4 in the cells was determined by real-time PCR and Western blot respectively, and the migration ability of the cells detected by Transwell migration and wound healing assays. The expression levels of MMP2, MMP9 and CXCR4 in the cells were measured by qRT-PCR, and those of Twist, Snail, E-cadherin and Vimentin by Western blot and by immunofluorescence assay, respectively. Results Compared with the p-Cont group, the human CRC HCT116 cells of the p-NDUFA4 group showed significantly up-regulated expressions of NDUFA4 mRNA ([0.96±0.15]% vs [1.94±0.08]%, P<0.05) and NDUFA4 protein ([0.06±0.05]% vs [1.07±0.12]%, P<0.05), increased in vitro migration ability ([29.51±3.17]% vs [54.36±4.08]%, P<0.01) and migrated cell rate ([0.99±0.12]% vs [1.85±0.10]%, P<0.01), elevated expression levels of MMP2, MMP9, CXCR4, N-cadherin,Vimentin, Snail and Twist, but down-regulated level of E-cadherin (P<0.05). Conclusion Overexpressed NDUFA4 promotes the epithelial-mesenchymal transition of human colorectal cancer cells.

OBJECTIVETo observe clinical effects of posterior short-segment fixation with undermining decompress by posterior ligament complex for the treatment of upper lumbar burst fractures.

METHODSFrom October 2010 to March 2013,23 patients with upper lumbar burst fractures (Denis B type) were treated by posterior short-segment fixation with undermining decompress by posterior ligament complex. There were 18 males and 5 females aged from 26 to 64 years old with an average of 45.7 years old. Twelve patients were caused by falling down, 5 cases were caused by traffic accident, 4 cases were the bruise injury caused by heavy object and 2 cases were caused by other injury. Fourteen patients were L1 fracture and 9 patients were L2 fracture. Thirteen patients were combined with nerve injuries (degree D according to ASIA classification). Internal fixation were removed from 12 to 20 months with an average of 14.3 months. JOA scores and imaging changes were recorded and compared at different time points.

RESULTSAll patients were followed up from 18 to 24 months with an average of 20.4 months. Thirteen patients with nerve injuries were completely recovered at 3 to 6 months after operation. JOA score at 1 year after operation was 20.63 ± 0.92, and 20.38 ± 1.06 at 3 months after removal of internal fixation,which were improved obviously than 9.90 ± 2.73 at 3 months after operation. (P > 0.05) Anterior height of injured vertebrae, vertebral body angle and local Cobb angle was (95.0 ± 0.53)%, (2.78 ± 1.36) and (2.43 ± 1.52) °respectively, and improved obviously than that of before operation (P < 0.05). There was no statistical significance in JOA scores at 3 months after removal of internal fixation and 1 year after operation (P > 0.05).

CONCLUSIONposterior short-segment fixation with undermining decompress by posterior ligament complex for the treatment of upper lumbar burst fractures has advantages of minimally invasive, could effective recover vertebrae height, maintain stability of spine, decrease low back pain. It is a safe and effective operative method.

OBJECTIVETo test whether the tumor vessel density (TVD) from the enhanced spiral CT can preoperatively predict nodal status and distant metastasis of colorectal cancer.

METHODSForty cases of colorectal cancer patients who received surgical treatment were included in this study. The three dimensional tumor vessels were reconstructed by an enhanced CT 64-slice spiral CT and its AW4.4 image processing platform. The TVD was measured by the 1000 high-resolution color graphics pathological analysis system. The TVD level was compared between different tumor size, classification, and TNM stage. The postoperative pathological staging was taken as golden standard.

RESULTSThe sensitivity, specificity and accuracy for direct prediction of lymph node metastasis by the enhanced CT 64-slice spiral CT was 74.1%(20/27), 53.8%(7/13) and 67.5%(27/40) respectively. The TVD from the reconstructed three dimensional tumor vessels in the group with lymph node metastasis was significantly higher than that without metastasis(0.070±0.046 vs. 0.037±0.013, P<0.05). The TVD in the distant metastasis group was significantly higher than that without distant metastasis (0.130±0.032 vs. 0.049±0.030, P<0.01). No difference of TVD was found between different tumor size, invasion depth, and differentiation type.

CONCLUSIONTVD level from the reconstructed three dimensional tumor vessels can indicate lymph node and distant metastasis of colorectal cancer.

OBJECTIVETo study the expression of A-kinase anchor protein 95 (AKAP95), cyclin E(2), and connexin 43 (Cx43) in lung cancer tissue, the clinical significance of their expression, and the expression correlation among the three proteins.

METHODSFifty-one samples of lung cancer tissue were examined by immunohistochemistry to measure the expression of AKAP95, cyclin E2, and Cx43.

RESULTSThe positive rate of AKAP95 expression in lung cancer tissue was significantly higher than that in paracancerous tissue (82.35% vs 33.33%, P < 0.05); AKAP95 expression was associated with the cell differentiation and histopathological type of lung cancer (P < 0.05). The positive rate of cyclin E(2) expression in lung cancer tissue was significantly higher than that in paracancerous tissue (43.14% vs 13.33%, P < 0.05); cyclin E(2) expression was associated with the lymph node metastasis and histopathological type of lung cancer (P < 0.05). The positive rate of Cx43 expression in lung cancer tissue was lower than that in paracancerous tissue (60.78% vs 80.00%); Cx43 expression was associated with the cell differentiation, lymph node metastasis, and histopathological type of lung cancer (P < 0.05). There was correlation between each two of AKAP95 expression, cyclin E(2) expression, and Cx43 expression in lung cancer tissue.

CONCLUSIONHigh expression of AKAP95 and cyclin E(2) plays an important role in the occurrence and development of lung cancer. AKAP95 expression is associated with the cell differentiation and histopathological type of lung cancer, and cyclin E2 expression is associated with lymph node metastasis and histopathological type. There is correlation between each two of AKAP95 expression, cyclin E(2) expression, and Cx43 expression in lung cancer tissue.
