Objective:To explore the effects of acupuncture combined with Buyang Huanwu Decoction on intestinal flora in cerebral blood flow hypo perfusion model rats with carotid artery stenosis.Methods:Totally 40 rats were randomly divided into sham-operation group, model group, TCM treatment group and acupuncture and drug combination treatment group, with 10 rats in each group. Except the sham-operation group, the other groups were prepared cerebral ischemia model by needle control and thread embolism method. TCM treatment group received Buyang Huanwu Decoction 100 mg/kg for gavage, once a day, and the intervention lasted for 2 weeks. In the acupuncture and drug combination group, based on the TCM treatment group, Baihui and its left and right sides of 2 mm were selected for acupuncture, once a day, and continuous intervention was performed for 2 weeks. Neurological function evaluation and behavioral function score were performed 7 and 14 days after administration, respectively. 16S rRNA sequencing was used to comprehensively characterize the structure and composition of fecal microflora of rats in each group. Linear discriminant analysis Effect Size (LEfSe) was used to analyze the difference of intestinal bacteria among groups.Result:On the 7th and 14th day after administration, compared with the model group, the neurological function score in the TCM treatment group and the acupuncture and drug combination group decreased ( P<0.05), and the behavioral function score increased ( P<0.05). Compared with model group, the Shannon index of TCM treatment group and acupuncture and drug combination group increased ( P<0.05). The abundance of Firmicutes increased ( P<0.05), and the abundance of Bacteroidetes and Proteobacteria decreased ( P<0.05); the abundance of Clostridia increased ( P<0.05), and the abundance of Gammaproteobacteria decreased ( P<0.05). The abundance of Escherichia-Shigella and Bacteroides decreased ( P<0.05); the abundance of lactobacillus significantly increased ( P<0.05). Conclusion:Acupuncture combined with Buyang Huanwu Decoction can improve the symptoms of cerebral hypoperfusion model rats with carotid artery stenosis, and the mechanism may be to increase the abundance of probiotics.

Objective To analyze the characteristics of work-related musculoskeletal disorders (WMSDs) among sonographers in Guangdong Province, and to explore the disease pattern of the cases. Methods A total of 512 sonographers from 31 hospitals in Guangdong Province were selected as the research subjects using stratified cluster sampling method. The prevalence of WMSDs in the past year was investigated using the Musculoskeletal Disorders Questionnaire, and the characteristics of WMSDs were analyzed. Latent class analysis was used to identify the disease pattern of WMSDs. Results The overall prevalence of WMSDs was 94.3%. The top five affected body parts were right shoulder, neck, right hand/wrist, lower back and right forearm/elbow, with the prevalence of 80.3%, 75.4%, 61.1%, 55.5% and 45.3%, respectively. The prevalence of WMSDs was higher on the right side for the shoulder, hand/wrist, forearm/elbow, hip/leg and knee compared with the left side (80.3% vs 31.3%, 61.1% vs 13.9%, 45.3% vs 10.0%, 17.4% vs 8.6%, 13.1% vs 8.4%, all P<0.05). The prevalence of WMSDs increased with work years, as well the prevalence of WMSDs in the top five affected body parts among the sonographers (all P<0.05). However, there were no statistical differences in prevalence of WMSDs between general hospitals and maternal and child health hospitals, tertiary hospitals and non-tertiary hospitals, Pearl River Delta hospitals and non-Pearl River Delta hospitals; there was also no statistical difference between different genders and age groups of the sonographers (all P>0.05). The best-fit latent disease pattern for sonographers WMSDs comprised three categories： symptom of neck-right shoulder, symptom of neck-lower back-right shoulder-right elbow-right hand/wrist, and symptom of multi-parts above the knees, with the latent probabilities of 0.438, 0.427 and 0.135, respectively. Conclusion The prevalence of WMSDs in sonographers is extremely high, with a dose-effect relationship with work years. The most common affected parts are neck, lower back and right shoulder, right hand/wrist, and right forearm/elbow. The prevalence of WMSDs in the right side of limb was higher than that in the left. WMSDs primarily occur in multiple parts simultaneously. The most common symptoms occur in the neck-right shoulder and neck-lower back-right shoulder-right elbow-right hand/wrist.

Pheochromocytoma/paraganglioma is an adrenal tumor that secrets catecholamines and is extremely rare in pregnant women. Its clinical presentation is lack of specificity, and the combination of low prevalence and nonspecific clinical presentation makes diagnosis and treatment difficult. In this study, the clinical data and prognosis of 5 pregnant patients with pheochromocytoma/paraganglioma were analyzed. It was found that hypertension first occurred in 4 patients during pregnancy, and the clinical manifestations of each case were different. Surgical treatment is the first choice in the treatment, patients who cannot operate can choose radionuclide therapy, chemotherapy and targeted therapy. Through follow-up, they all showed recurrence and metastasis at different times. Among them, the patients who continued to be pregnant to the middle and late stages of surgical treatment progressed rapidly, and there were multiple bone metastases throughout the body in a short period of time, and two cases died in a short period of time. Therefore, effective diagnosis, individualized treatment and lifelong follow-up are particularly important.

Objective:To observe and compare the efficacy and safety of glucosamine sulfate (GS) and chondroitin sulfate (CS) in the treatment of adult Kashin-Beck disease (KBD), so as to provide effective medical evidence for the standardized treatment of adult KBD.Methods:A clinical randomized controlled trial was conducted in Fuyu County and Shangzhi City, KBD historical seriously ill areas in Heilongjiang Province. A total of 247 patients were selected according to the standard of "Diagnosis of Kashin-Beck Disease" (WS/T 207-2010). According to gender, age and KBD condition, they were randomly divided into GS and CS groups, 124 and 123 respectively. Follow up once a month to investigate the medication and clinical symptoms of patients, and distribute drugs for the next stage. Fasting blood and urine samples were collected before, during and at the end of treatment (0, 90 and 180 d). Serum interleukin (IL)-1β content and urine pyridine (PYD) level were measured by enzyme-linked immunosorbent assay (ELISA). The visual analogue scale (VAS) score, affected joints, self-evaluation of curative effect and side effects were evaluated through the questionnaire, joint dysfunction and drug efficacy were evaluated according to the criteria of "Evaluation of Therapeutic Effect of Kashin-Beck Disease" (WS/T 79-2011).Results:Expression of cytokines related to cartilage metabolism: at 180 d of treatment, serum IL-1β contents and urinary PYD levels in GS and CS groups were lower than those at 0 d of treatment ( Z = - 2.461, - 2.160, - 5.075, - 5.471, P < 0.05). VAS score: at 90 and 180 d of treatment, the scores of knee pain, stiffness and function in GS and CS groups were lower than those at 0 d of treatment ( P < 0.05); and at 180 d of treatment, the scores of knee stiffness and function in GS group were lower than those in CS group ( P < 0.05). Evaluation of affected joints: at 90 and 180 d of treatment, the scores of joint pain, swelling and stiffness in GS and CS groups were lower than those at 0 d of treatment ( P < 0.05). Self-evaluation of curative effect: at 180 d of treatment, the self-evaluation of curative of CS group were better than that at 90 d of treatment (χ 2 = 9.376, P < 0.05). Evaluation of side effects: at 90 and 180 d of treatment, the side effects in GS and CS groups were mainly gastrointestinal symptoms. Joint dysfunction score: at 90 d of treatment, the sum of effective rate and markedly effective rate in GS group was higher than that in CS group (χ 2 = 4.042, P < 0.05), but there was no significant difference between the two groups at 180 d of treatment (χ 2 = 0.869, P > 0.05). Conclusion:GS and CS have certain therapeutic effects on adult KBD, which can improve symptoms and reduce serum IL-1β content and urinary PYD level, but GS takes effects quickly, and its effect on improving joint stiffness and function are better than CS.

Objective:To observe and compare the therapeutic effects of glucosamine sulfate (GS) and diacerein (DCN) on adult Kashin-Beck disease (KBD).Methods:A clinical randomized controlled trial was conducted in the historical severe KBD areas Fanrong Township, Fulu Town, Long'anqiao Town, Lianghe Town, Shaowen Township of Heilongjiang Province, and 240 patients were selected according to the criteria of "Diagnosis of Kashin-Beck Disease" (WS/T 207-2010), then divided into GS and DCN groups (gender, age, and KBD condition balanced) via the random number table method, with 120 patients in each group. Followed up once a month to investigate the patient's medication and clinical symptoms, and distributed drugs for the next stage. Fasting blood samples and urine samples were collected before, during, and at the end of treatment (0, 90, and 180 days). Enzyme-linked immunosorbent assay (ELISA) was used to detect the serum interleukin (IL)-1β level and urine pyridinol (PYD) level. Visual analog scale (VAS) scores, evaluation of affected joints, self-evaluated efficacy, and evaluation of adverse reactions were carried out through questionnaires. Joint dysfunction scores and medications efficacy determination were performed according to the "Judgment of Kaschin-Beck Disease Treatment Effect" (WS/T 79-2011).Results:Expression of cytokines related to cartilage metabolism: after 180 days of treatment, serum IL-1β levels, urine PYD levels in GS group and urine PYD levels in DCN group were lower than those in the same group at 0 day of treatment ( Z = - 2.332, - 5.420, - 5.204, P < 0.05). VAS scores: after 90 days of treatment, the pain, stiffness scores of patients in GS group and the pain, stiffness, and function scores in DCN group were lower than those in the same group at 0 day of treatment ( Z = - 2.612, - 2.359, - 3.637, - 2.881, - 2.238, P < 0.05); after 180 days of treatment, the pain, stiffness and function scores of patients in GS and DCN groups were significantly lower than those of the same group at 0 day of treatment ( Z = - 6.738, - 9.530, - 7.781, - 5.428, - 3.761, - 3.587, P < 0.01). Evaluation of affected joints: after 90 and 180 days of treatment, except for pain of weather changes in DCN group, the scores of symptomatic joints in the two groups were lower than those at 0 day of treatment ( P < 0.05). Efficacy self-evaluation: after 180 days of treatment, the self-evaluated efficacy ratio of DCN group was higher than that of GS group and the same group after 90 days of treatment (χ 2 = 4.165, 4.022, P < 0.05). Evaluation of adverse reactions: after 90 and 180 days of treatment, the main adverse reactions of patients in GS and DCN groups were gastrointestinal symptoms. Joint dysfunction scores: after 90 days of treatment, the sum of the effective rate and the markedly effective rate of GS group was higher than that of DCN group (χ 2 = 4.993 , P < 0.05); while after the 180 days of treatment, there was no significant difference between the two groups (χ 2 = 0.417 , P > 0.05). Conclusions:Both GS and DCN have a certain therapeutic effect on adult KBD and can improve clinical symptoms. The GS takes effect quickly, and long-term use can protect cartilage from inflammatory factors to a certain extent.

Objective:To investigate the effects of glucosamine sulfate, chondroitin sulfate and diacetarine on urinary renal function indexes UREA, creatinine (CREA), urinary microprotein(mALB) and N-acetyl-β-D-glucosidase (NAG) in adult patients with Kashin-Beck disease.Methods:According to the criteria of "Diagnosis of Kashin-Beck Disease" (WS/T 207-2010), adult patients with degrees Ⅰ and Ⅱ Kashin-Beck disease in Heilongjiang Province were selected in 2019. They were randomly divided into three treatment groups according to age, gender, disease classification and other condition by clinical randomized controlled trial, group A (glucosamine sulfate group), group B (chondroitin sulfate group) and group C (diacetarine group). Fasting mid-morning urine was collected at 0, 90 and 180 days of treatment. The levels of UREA, CREA, mALB and NAG were measured using an automatic biochemical analyzer. And the abnormal rates of the above indexes were analyzed.Results:At 0 day of treatment, there were 118, 99 and 116 people in the 3 groups, respectively; after 90 days of treatment, 115, 93 and 106 people remained in the 3 groups; after 180 days of treatment, 95, 80 and 93 people remained in the 3 groups. The results showed that there was no significant difference in the levels of UREA, CREA, NAG and mALB among the 3 groups at 0 and 180 days of treatment ( H = 0.055, 0.923, 0.276, 1.125, 1.635, 3.873, 1.045, 4.135, P > 0.05). After 90 days of treatment, there was no significant difference in CREA level among the 3 groups ( H = 1.719, P > 0.05), the levels of UREA and NAG in group C were higher than those in group B ( P < 0.05), and the level of mALB in group B was higher than that in group C ( P < 0.05). The comparison results of all indexes before and after treatment showed that after 90 days of treatment, the levels of mALB in the 3 groups were lower than those of 0 day ( Z = - 2.858, - 3.217, - 2.124, P < 0.05), the levels of NAG were higher than those of 0 day ( Z = - 3.700, - 2.222, - 4.672, P < 0.05); and the level of UREA in group C was higher than that of 0 day ( Z = - 2.393, P < 0.05). After 180 days of treatment, the levels of CREA in the 3 groups were higher than those of 0 day ( Z = - 5.853, - 6.984, - 6.255, P < 0.05), and the levels of mALB in the 3 groups were lower than those of 0 day ( Z = - 3.785, - 2.624, - 3.427, P < 0.05). The abnormal rates of CREA in the 3 groups after 180 days of treatment were higher than those of 0 and 90 days (χ 2 = 39.499, 37.707, 71.534, 57.959, 58.160, 55.129, P < 0.05). There was no significant difference in the abnormal rate of CREA between 0 day and 90 days of treatment (χ 2 = 0.004, 2.068, 0.053, P > 0.05). The abnormal rates of NAG in groups A and C after 90 days of treatment were higher than those of 0 day (χ 2 = 8.999, 11.227, P < 0.05). The abnormal rates of NAG in group C after 180 days of treatment was higher than that of 0 day (χ 2 = 5.006, P < 0.05). There was no significant difference in the abnormal rate of NAG between group A and group C after 90 days and 180 days of treatment (χ 2 = 1.976, 1.413, P > 0.05). The abnormal rates of mALB in groups A and B after 90 days and 180 days of treatment were lower than those of 0 day (χ 2 = 6.461, 8.881, 7.563, 4.999, P < 0.05), and there was no significant difference between 90 days of treatment and 180 days of treatment (χ 2 = 0.638, 0.013, P > 0.05). Conclusions:The effects of glucosamine sulfate, compound chondroitin sulfate and diacetarine on renal function of the patients are not significantly different after 180 days of medication, but the three drugs all have certain effects on CREA and NAG. Follow-up work should be done during drug treatment to closely monitor the changes of the two indicators.

Objective To observe the brain tissue recovery in patients with bilateral chronic subdural hematomas after drilling and drainage treatments. Methods The clinical data of 143 patients with bilateral chronic subdural hematoma performed drilling and drainage in our hospital from January 2011 to December 2016 were collected, including gender, age, the longest and widest diameters of the skull and the longest diameter of the initial hematoma, the widest diameter of the initial hematoma, the widest diameter of the postoperative hematoma, and other clinical information. The postoperative absorption of hematoma and recovery of brain tissues were analyzed. Results In these 143 BCSDH patients, 119 were male and 24 were male; the mean age of these patients was (67.7 ±1.1) years (21-92 years old), and the mean age of male patients was (67.2 ±1.2) years and the mean age of female patients was (70.2±2.5) years. The longest diameters of the skull was 134.8 mm-177.8 mm (averaged 155.5 mm± 0.7 mm) and the widest diameters of the skull was 113.5 mm-147.0 mm (averaged 131.7 mm±0.5 mm). The longest diameters of the left and right initial hematomas were (113.4±2.5) mm and (117.6±2.1) mm,and the widest diameters of the left and right initial hematomas were (15.8±0.5) mm and (17.2±0.8) mm. There was no significant difference in the recovery rate of brain tissues between patients with different gender, age or lesion sides (P<0.05). The recovery rate of brain tissues was positively correlated with the longest and widest diameters of initial hematomas (r=0.143, P=0.018; r=0.181, P=0.002). A total of 58 patients (40.6％) presented a single-side distance<10 mm from the brain tissue to the inner edge of the skull within one week after surgery, and a total of 48 patients (33.6％) showed both sides brain recovery to<10 mm. Conclusions Drilling and drainage are the first line treatment for patients with bilateral chronic subdural hematoma and contribute to the re-location of brain tissues. The rate of brain tissue recovery is positively correlated with the size of primary hematoma.

Objective To investigate the clinical efficacy and prognosis of transcatheter arterial chemoembo-lization(TACE)combined with radiofrequency ablation(RFA)in treatment of liver cancer.Methods 64 patients of liver cancer were selected as the research subjects,and they were divided into two groups by randomized single blind method.32 cases in the control group adopted the TACE treatment,while 32 cases in the observation group were given TACE combined with RFA.The tumor shrinkage,complete necrosis rate,local recurrence rate,AFP levels and adverse reactions of the two groups were compared.The patients were followed up for 3 years to record survival.Results After treatment,the tumor shrinkage rate and complete necrosis rate of the observation group were 90.63% and 75.00%, which were significantly higher than 68.75% and 50.00% of the control group,the differences were statistically significant (χ2 =8.453,8.203,all P <0.05).The local recurrence rate of the observation group was 21.88%,which was significantly lower than 43.75% of the control group,the difference was statistically significant(χ2 =7.887,P <0.05).After treatment,the AFP level of the observation group was (70.11 ±6.45 )ng/L,which was significantly lower than (157.76 ±10.42)ng/L in the control group,the difference was statistically significant (t =7.433,P <0.05).The survival rates of 1 year,2 years and 3 years in the observation group were 84.38%,71.88%,56.25%, which were significantly higher than 65.63%,53.13%,31.25% in the control group (χ2 =8.677,8.203,8.985,all P <0.05).The incidence rate of postoperative adverse reaction had no significant difference between the two groups (χ2 =1.337,P >0.05 ).Conclusion TACE combined with RFA in treatment of liver cancer can significantly improve the effect of tumor necrosis rate,reduce the local recurrence rate and prolong the survival time of the patients, and it had less adverse reaction,higher safety,and which should be applied in clinical.
