Clinical Study on the Treatment of Non-isotropic Cervical Spondylosis by Neck Pain Granules Combined with Tuina.

BACKGROUND: Cervical spondylotic radiculopathy is a common form of cervical spondylosis caused by degeneration of the cervical spine. Currently, non-surgical treatment is the preferred treatment method, and Chinese medicine is widely used. OBJECTIVE: To investigate the effect of radiculopathy spondylosis by tuina spinning and lifting technique. EXPERIMENTAL DESIGN: We conducted a 12-week, open-label, analyst-blinded, randomized clinical trial ( 2 weeks of intervention plus 10 weeks of observational follow-up ). A total of 25 patients with radiculopathy were collected, and data was analyzed during the treatment and recovery period. INTERVENTIONS: Neck pain granules group: a package of oral neck pain granules after meals, three times a day, treatment for 2 weeks; neck pain granules combined with massage lifting technique, treatment group: use, massage lifting technique treatment, once every two days, normal take neck pain granules, treatment for 2 weeks. All cases were followed up for 2.5 months. Main monitoring indicators: Visual Analog Scale, Neck Dysfunction Index score, and Tanaka jiu ( Tanaka Yasuhisa Cervical Spondylosis Symptom Scale ) were recorded on time, and statistical statistics were made. RESULT: The scores of VAS and NDI were significantly more effective in the neck pain granules combined with the tuina group than in the neck pain granules group, while the Tanaka Yasuhisa Cervical Spondylosis Symptom Scale was not significantly different between the two groups. CONCLUSION: The treatment effect of neck pain granules combined with tuina was significantly better than that of traditional Chinese medicine alone.

Analysis of laboratory and serological test results in patients with acute brucellosis during follow-up.

BACKGROUND: The laboratory test results and serum-specific antibodies of patients with acute brucellosis initial infection were followed up and analyzed. METHODS: 70 patients in Hohhot City, Inner Mongolia Autonomous Region, with acute brucellosis were followed up for 360 days. Serum samples were collected at 0, 15, 30, 60, 90, 180, and 360 days after diagnosis and analyzed by Rose Bengal plate test (RBPT), colloidal gold test paper (GICA), and test tube agglutination test (SAT). The serum-specific antibodies IgG and IgM were detected. RESULTS: RBPT results: False negative (-) gradually increased with the extension of the course of disease, with the largest change in 30-60 days after diagnosis, and the constituent ratio increased by 12.9%. GICA results: The false negative increased with the course of disease, and the constituent ratio of false negative was 20.0% after 180 days of diagnosis. SAT results: 1:100 positive showed a ladder like decrease with the increase in the course of disease, and the largest decrease was 90-180 days, with a decrease of 34.3% in the constituent ratio. 360 days after diagnosis, the constituent ratio of positive was only 14.3%. During the follow-up period, the IgG average value fluctuated and the average IgM value decreased. CONCLUSION: The false-negative results of RBPT, GICA, and SAT increased with the course of disease, and the false-negative rates were higher than 20% after half a year. IgM level is beneficial to the early diagnosis of brucellosis, while IgG level is helpful to the judgment of brucellosis stage.

Anti-apoptosis mechanism of triptolide based on network pharmacology in focal segmental glomerulosclerosis rats.

Triptolide (TPL), the active component of Tripterygium wilfordii, exhibits anti-cancer and antioxidant functions. We aimed to explore the anti-apoptosis mechanism of TPL based on network pharmacology and in vivo and in vitro research validation using a rat model of focal segmental glomerulosclerosis (FSGS). The chemical structures and pharmacological activities of the compounds reported in T. wilfordii were determined and used to perform the network pharmacology analysis. The Traditional Chinese Medicine Systems Pharmacology Database (TCMSP) was then used to identify the network targets for 16 compounds from Tripterygium wilfordii. Our results showed that 47 overlapping genes obtained from the GeneCards and OMIM databases were involved in the occurrence and development of FSGS and used to construct the protein-protein interaction (PPI) network using the STRING database. Hub genes were identified via the MCODE plug-in of the Cytoscape software. IL4 was the target gene of TPL in FSGS and was mainly enriched in the cell apoptosis term and p53 signaling pathway, according to Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses. TPL inhibited FSGS-induced cell apoptosis in rats and regulated IL4, nephrin, podocin, and p53 protein levels via using CCK8, TUNEL, and Western blot assays. The effects of IL4 overexpression, including inhibition of cell viability and promotion of apoptosis, were reversed by TPL. TPL treatment increased the expression of nephrin and podocin and decreased p53 expression in rat podocytes. In conclusion, TPL inhibited podocyte apoptosis by targeting IL4 to alleviate kidney injury in FSGS rats.

Role of Diffusional Kurtosis Imaging in Evaluating the Efficacy of Transcatheter Arterial Chemoembolization in Patients with Liver Cancer.

Objective: To explore the role of diffusional kurtosis imaging (DKI) in evaluating the efficacy of transcatheter arterial chemoembolization (TACE) in patients with liver cancer. Materials and Methods: A total of 54 patients with primary liver cancer underwent TACE were selected as the study subjects. Magnetic resonance imaging and DKI scans were carried out before and after TACE, and the relevant parameters were analyzed. Results: Compared with those before TACE, the values of radial diffusivity (Dr), axial diffusivity (Da), and mean diffusivity (MD) of tumor tissues in the patients after TACE were significantly increased, whereas the values of axial kurtosis (Ka), fractional anisotropy of kurtosis (FAk), hepatic blood volume (HBV), hepatic blood flow (HBF), and hepatic artery perfusion (HAP) were notably decreased (p < 0.05). There were no significant changes regarding FA, radial kurtosis (Kr), mean kurtosis (MK), hepatic arterial fracture (HAF), permeability-surface area product (PS), mean transit time (MTT), and portal vein perfusion (PVP) (p > 0.05). The differences in apparent diffusion coefficients (ADCs) of different liver cancer tissues in patients under different b values after operation were statistically significant, and the ADC values of liver cancer tissues were evidently higher than those of other tumor tissues (p < 0.05). Conclusion: DKI is characterized with advantages such as fastness, simpleness, high resolution, and impregnability of the density of lipiodol. It can not only directly reflect the changes in blood perfusion at the lesion but also accurately and efficiently evaluate the remnants, necrosis, and recurrence of tumor tissues based on changes in ADC under different b values. It provides certain clinical assistance for the evaluation of the efficacy before and after TACE.

Segmentation of pulmonary vascular tree by incorporating vessel enhancement filter and variational region-growing.

BACKGROUND: Automatic segmentation of pulmonary vascular tree in the thoracic computed tomography (CT) image is a promising but challenging task with great clinical potential values. It is difficult to segment the whole vascular tree in reasonable time and acceptable accuracy. OBJECTIVE: To develop a novel pulmonary vessel segmentation approach by incorporating vessel enhancement filters and the anisotropic diffusion filter with the variational region growing. METHODS: First, the airway wall from the lung lobes is eliminated from CT images by using multi-scale morphological operations. Second, a Hessian-based multi-scale vesselness filter and medialness filter are applied to detect and enhance the potential vessel. Third, an anisotropic diffusion filter is used to remove noise and enhance the tube-like structures in CT images. Last, the vascular tree is segmented by applying variational region growing algorithm. RESULTS: Applying to the CT images collected from the entire dataset of VESSEL12 challenge, we achieved an average sensitivity of 92.9%, specificity of 91.6% and the area under the ROC curve of AUC = 0.972. CONCLUSIONS: This study demonstrated feasibility of segmenting the pulmonary vessel effectively by incorporating vessel enhancement filters and the anisotropic diffusion filter with the variational region growing algorithm. Our method cannot only segment both large and peripheral vessels, but also distinguish the vessels from the adjacent tissues, especially the airway walls.

Preptin is a new predictor of coronary artery calcification.

BACKGROUND: We aimed to assess whether an elevated preptin level is associated with coronary artery calcification (CAC). METHODS: Two hundred and twenty participants with suspected cardiovascular disease were recruited. CAC was measured using 320-row-detector dynamic volume CT, and the patients were divided into 2 groups: the non-CAC group (with an Agatston score = 0) and the CAC group (with an Agatston score > 0). RESULTS: The serum preptin level was significantly elevated in the CAC group compared with the non-CAC group. In logistic regression analysis, preptin, as well as age, gender, hypertension history and history of ß-blocker use, were independent predictors of a positive CAC score. The highest preptin quintile of patients had a higher CAC level compared with other quintiles. Binary logistic regression analyses showed that the highest preptin quintile had a 2.9-time increased odds ratio of an elevated CAC level than the other 4 quintile patients. CONCLUSIONS: This study demonstrated that serum preptin was associated with coronary artery calcification.

Diagnostic utility of CT in differentiating between ruptured ovarian corpus luteal cyst and ruptured ectopic pregnancy with hemorrhage.

BACKGROUND: To evaluate the performance of computed tomography (CT) as a diagnostic aid to differentiate between ruptured ovarian corpus luteal cyst (ROCLC) and ruptured ectopic pregnancy with hemorrhage (REPWH). METHODS: A total of 36 patients treated at our hospitals for ROCLC and REPWH from June 2014 to August 2017 were included in this study. Based on the diagnosis, the study population was divided into ROCLC group (n = 21) and REPWH group (n = 15). CT scans were performed for all patients prior to treatment. The size of the cystic shadows and the depth of the pelvic effusion were analyzed and compared with independent sample Student's t test and Fisher's exact test. RESULTS: Cystic shadows with maximum diameters ≥3.0 cm presented in 16 patients with ROCLC and 1 patient with REPWH, while 4 patients with ROCLC and 9 patients with REPWH exhibited cystic shadows with maximum diameters <3.0 cm. The mean diameters along the major and minor axes in the two groups were 3.76 ± 1.11 cm and 2.93 ± 0.98 cm, 1.96 ± 0.65 cm and 1.60 ± 0.55 cm, respectively (p < 0.001). The mean depth of the pelvic effusion in patients with ROCLC and REPWH were 5.20 ± 2.47 cm and 6.96 ± 2.07 cm, respectively (p = 0.038). CONCLUSION: The cystic shadow of ROCLC is larger than that of the REPWH. The depth of the pelvic effusion of REPWH is deeper than that of the ROCLC. CT can help differentiate between ROCLC and REPWH based on the size of the cystic shadow and the depth of pelvic effusion in the adnexal area.

Diagnosis of ovarian vein syndrome (OVS) by computed tomography (CT) imaging: a retrospective study of 11 cases.

This article aims to explore the characteristics of computed tomography (CT) images of ovarian vein syndrome (OVS). The approval of the research ethics committee and the written informed consent of the patients were obtained. The CT images of 11 patients who had been diagnosed with OVS were retrospectively analyzed. All patients were examined with CT urogram, both plain CT scans and enhanced CT scans (including arterial phase, venous phase, and secretory phase). The datum was pulled into a computer workstation for post-processing. Ureteral obstruction at the position and ureteral dilation above it, where the ovarian vein crosses over the ureter, were found in all 11 patients. In addition, 4 patients presented with right upper ureteric calculi, 10 with right renal calculi (including 8 patients with multiple renal calculi that also had obvious uronephrosis), and 2 with a urinary calculus or cystolith. The diameter of the ovarian vein in them ranged from 5 mm to 13 mm. Varicose veins around the uterus were found in 2 patients, and the diameter of the left ovarian vein was larger than 7 mm in 1 patient.In conclusion, analysis of CT images is a vital method in diagnosing OVS.

[Correlation study between PSG parameters and CT measurements in upper airway of OSAHS patients before and after UPPP].

OBJECTIVE: To investigate the correlation of polysomnography parameters and CT measurements in upper airway of mild and severe obstructive sleep apnea hypopnea syndrome (OSAHS) patients before and after uvulopalatopharyngoplasty (UPPP). METHOD: Having PSG detection and spiral computed tomograph scan for 30 mild and severe OSAHS patients both before and after UPPP operation, compare the morphology change of upper airway on CT measurements, use pearson correlation analysis to analysis the correlation between the minimum cross-sectional area, left and right diameter, anteroposterior diameter in upper airway and apnea hypopnea index (AHI). RESULT: The difference of the minimum cross-sectional area, left and right diameter, anteroposterior diameter in upper airway before and after UPPP operation was significant. The minimum cross-sectional area, left and right diameter was negatively correlated with AHI; Left and right diameter was not correlated with AHI. CONCLUSION: The minimum cross-sectional area, left and right diameter, anteroposterior diameter after operation is bigger than before operation. The minimum cross-sectional area, left and right diameter is negatively correlated with AHI.

MLVA genotyping of Brucella melitensis and Brucella abortus isolates from different animal species and humans and identification of Brucella suis vaccine strain S2 from cattle in China.

In China, brucellosis is an endemic disease and the main sources of brucellosis in animals and humans are infected sheep, cattle and swine. Brucella melitensis (biovars 1 and 3) is the predominant species, associated with sporadic cases and outbreak in humans. Isolates of B. abortus, primarily biovars 1 and 3, and B. suis biovars 1 and 3 are also associated with sporadic human brucellosis. In this study, the genetic profiles of B. melitensis and B. abortus isolates from humans and animals were analyzed and compared by multi-locus variable-number tandem-repeat analysis (MLVA). Among the B. melitensis isolates, the majority (74/82) belonged to MLVA8 genotype 42, clustering in the 'East Mediterranean' group. Two B. melitensis biovar 1 genotype 47 isolates, belonging to the 'Americas' group, were recovered; both were from the Himalayan blue sheep (Pseudois nayaur, a wild animal). The majority of B. abortus isolates (51/70) were biovar 3, genotype 36. Ten B. suis biovar 1 field isolates, including seven outbreak isolates recovered from a cattle farm in Inner Mongolia, were genetically indistinguishable from the vaccine strain S2, based on MLVA cluster analysis. MLVA analysis provided important information for epidemiological trace-back. To the best of our knowledge, this is the first report to associate Brucella cross-infection with the vaccine strain S2 based on molecular comparison of recovered isolates to the vaccine strain. MLVA typing could be an essential assay to improve brucellosis surveillance and control programs.
