Application of ultrasound-guided selective nerve branch blockage in lumbar spinal nerve posterior branch syndrome / 中国骨伤

OBJECTIVE@#To investigate the efficacy and safety of ultrasound-guided selective nerve branch blockage in the treatment of lumbar spinal nerve posterior branch syndrome.@*METHODS@#A total of 40 patients with lumbar spinal nerve posterior branch syndrome treated by Pain Clinic from May 2017 to December 2018 were selected. According to the method used in locating site for nerve blockage, the patients were divided into ultrasound-guided group and anatomical positioning group, with 20 cases in each group. In anatomical positioning group, there were 7 males and 13 females, aged (63.42±7.71) years old, weighted (63.65±10.72) kg, numerical rating scale (NRS) was (6.61±1.52) scores, course of disease was (16.55±4.68) months. Pain sites:4 cases at L@*RESULTS@#There were no statistically significant differences in gender, age, weight, NRS, course of disease and pain segment distribution between two groups (@*CONCLUSION@#Comparedwith anatomicalpositioning, ultrasound-guided selective nerve branch block for the treatment of posterior branch of the lumbar spinal cord syndrome can reduce the number of treatments and maintain a longer therapeutic effect, but it is also necessary to pay attention to the time of each treatment to avoid dizziness and other adverse reactions.

Effect of cadmium chloride on the expression of KIM-1 in in vitro HK-2 cell culture / 中国职业医学

OBJECTIVE: To investigate the effect of cadmium chloride on the expression of kidney injury molecule-1( KIM-1)in human renal tubular epithelial cells( HK-2 cells). METHODS: HK-2 cells at logarithmic phase were divided into a control group and 5 treatment groups that were treated with 5. 0,10. 0,20. 0,50. 0 and 100. 0 μmol / L of cadmium chloride dissolved in phosphate buffer solution. Cell pathology observation was carried out after 24 hours of cultivation. The methyl thiazolyl tetrazolium assay was used to calculate the survival rate of HK-2 cells. The expression of KIM-1 mRNA and protein were detected by the reverse transcription-polymerase chain reaction and Western blotting analysis respectively.RESULTS: There were no cellular morphologic change in HK-2 cells in the control group,the 5. 0 and 10. 0 μmol / L groups;the HK-2 cells showed different degree of swellings or vacuoles in the 20. 0 and 50. 0 μmol / L groups; a large number of cells were found dead in the 100. 0 μmol / L group. The cell survival rates of HK-2 cells in the 20. 0,50. 0 and 100. 0μmol /L groups were lower than those of control group,the 5. 0 and 10. 0 μmol /L groups( P < 0. 05). The pairwise comparison among survival rates of the 20. 0,50. 0 and 100. 0 μmol / L groups showed significant difference( P < 0. 05).The expression levels of KIM-1 mRNA and protein in the 20. 0 and 50. 0 μmol / L groups were higher than those of control group,the 5. 0 and 10. 0 μmol / L groups( P < 0. 05). The levels of KIM-1 mRNA and protein in the 50. 0 μmol / L group were higher than those of the 20. 0 μmol / L group( P < 0. 05). CONCLUSION: Cadmium chloride at certain concentration can increase the expression of KIM-1 mRNA and protein in HK-2 cells. Therefore,the expression of KIM-1 could be used as one of the effect biomarkers for cadmium induced kidney tubule injury.

Effect of Norvasc and Tanatril on circadian rhythm of blood pressure in hypertensive patients / 中国地方病学杂志

Objective To observe the circadian rhythm of blood pressure and investigate the impact of Norvasc and Tanatril administrated at different time points based on the theory of time therapeutics in hypertensive patients. Methods The 24-hour ambulatory blood pressure was monitored in 130 inpatients and outpatients with grade 3 or 2 hypertension from May 2008 to November 2009. A total of 34 dipper hypertensive patients were grouped into dipper blood pressure group and 5 mg/d of Norvasc and Tanatril were taken by them at 6:00 AM. A total of 96 nondipper hypertensive patients were further divided into three subgroups after adjustment for age and gender: 5 mg/d of Norvasc and Tanatril were taken by group I (n = 30) at 6:00 AM; 5 mg/d of Tanatril at 6:00 AM and 5 mg/d of Norvasc at 18:00 PM by group Ⅱ (n = 32); 5 mg/d of Norvasc at 6:00 AM and 5 mg/d of Tanatrilat 18:00 PM by group Ⅲ(n=34).The 24-hour ambulatory blood pressure monitoring was performed again after four weeks treatment and 24-hour mean systolic blood pressure(24 hSBP),24-hour mean diastolic blood pressure(24 hDBP),daytime and nighttime mean systolic blood pressure(dSBP,nSBP)and daytime and nighttime mean diastolic blood pressure(dDBP,nDBP),were analyzed.Results The 24 hSBP,24 hDBP and dSBP,and dDBP were reduced from(154.3±5.6),(95.4±3.1),(158.7±6.5),(99.6±3.7)mmHg to(137.2±3.9),(82.5±2.7),(139.7±3.8),(85.2±3.5)mmHg,respectively,in dipper blood pressure group(t=2.124,2.356,2.278,2.449,all P<0.05).The 24 hSBP and 24 hDBP of the three groups in nondipper blood pressure were decreased from(154.4±6.1),(156.7±6.7),(156.6±5.2),(95.8±2.8),(94.9±3.8),(95.7±3.2)mmHg to (139.6±4.1),(134.5±4.6),(133.4±3.5),(83.5±4.2),(80.8±5.6),(81.6±4.7)mmHg,respectively(t=2.038,2.040,2.135,2.142,2.213,2.216,all P<0.05).dSBP and dDBP were decreased from(158.6±3.50),(158.4±5.6),(159.5±4.),(98.4±3.7),(99.6±3.7),(83.9±5.2)mmHg to(138.9±5.4),(136.7±4.1),(137.4±6.4),(85.8±5.3),(83.6±5.1),(83.9±5.2)mmHg,respectively(t=2.021,2.252,2.261,2.217,2.167,2.076,all P<0.05).nSBP and nDBP were decreased from(146.7±6.9),(149.8±3.9),(150.2±4.1),(93.7±4.2),(95.7±4.3),(93.4±3.3)mmHg to(133.7±4.6),(129.8±5.7),(127.6±2.8),(87.8±2.9),(78.5±6.4),(77.8±4.8)mmHg,respectively(t=1.798,2.032,2.014,1.864,2.157,2.166,all P<0.05).There were significant differences in nSBP and nDBP among all groups after treatment(F=2.32,2.17,all P<0.05),and the effect of the drugs was better in groug Ⅱ and Ⅲ than in group Ⅰ(q=3.17,4.03,3.32,4.19,all P<0.05),but there were no significant differences between group Ⅱ and Ⅲ(P>0.05).Conclusions Blood pressure can be controlled effectively by taking two antihypertensive medictions in the morning in hypertensive dipper patient but the blood pressure of nondipper hypertensive patients were able to be controlled more efficiently by taking the two antihypertensive medictions separately in the morning and at the evening compared with that taking the two drugs together in the morning.

Clinical study on needle-pricking therapy for treatment of polycystic ovarial syndrome / 中国针灸

<p><b>OBJECTIVE</b>To probe into the clinical effect of needle-pricking therapy for treatment of polycystic ovarial syndrome.</p><p><b>METHODS</b>One hondred and twenty-one cases of polycystic ovarial syndrome were divided into a needle-pricking therapy group of 61 cases and a medication group of 60 cases with randomized and controlled method. The needle-pricking therapy group were treated by needle-pricking therapy at sacral plexus stimulating points on both sides of the spine and lateral points of Dazhui (CV 14), and the medication group by oral administration of domiphen and intramuscular injection of chorionic gonadotropin (HCG).
