Objective To investigate the medium-and long-term clinical efficacies of superficial needling therapy for lumbodorsal myofacial pain syndrome.Method Three thousand two hundred and fifty-one patients with lumbodorsal myofacial pain syndrome were randomly allocated to a superficial needling group of 1753 cases and an acupuncturegroupof 1498 cases.Seventy-threepatients in the superficial needling group and 105 patients in the acupuncture group did not complete the required courses of treatment and were lost to follow-up.The others in the two groups completed therequiredcourses of treatment and were followed up.After three courses of treatment, the clinical therapeutic effects were compared using the pain score at the end of treatment and at three and six months and one year after.Thereturn visit rates were also compared.Result There was a significant difference in the pain score (NRS score) between the two groupsat the end of treatment (P<0.01), which was significantly lower in the superficial needling group than in the acupuncturegroup, and a difference between the twogroupsat three months after.There was no significant difference in the pain score between the two groupsat six months after and no difference between the two groupsat one year after.There were no differences in clinical the rapeutic effect and the return visit rate between the two groupsat six months and one year after.Conclusion A clinical observation with a large sample shows that superficial needling has a good short-term therapeutic effect on lumbodorsal myofacial pain syndrome and is a safe and effective method, but its medium-and long-term the rapeutic effects are notgood enough.

ObjectiveTo explore the correlation between butylphthalide and plasma brain-type creatine kinase isoenzyme (CK-BB),endothelin (ET),calcitonin gene related peptide (CGRP) in patients with acute cerebral infarction (ACI).MethodsSixty patients with ACI were divided into treatment group and control group with 30 cases each by random digits table method.Both groups received normal treatment continuously for 7 days,and butylphthalide of 200 mg was added to treatment group for 3 times per day.The levels of plasma CK-BB,ET and CGRP of two groups before and after treatment were measured and compared.ResultsThe levels of plasma CK-BB,ET of two groups both decreased significantly after treatment,but CGRP rose obviously.It showed significant differences before and after treatment of both groups (P ＜0.01 or ＜ 0.05).The levels of plasma CK-BB,ET of treatment group after treatment were lower than those of control group in the same period [(216.48±36.95) U/L vs.(333.07±54.03) U/L,(83.33±26.48)ng/L vs.(98.46±31.46) ng/L,P ＜ 0.05 ].The level of plasma CGRP of treatment group after treatment was significantly higher than that of control group in the same period [ (44.16±13.28 ) ng/L vs.(36.42±12.31 )ng/L,P ＜ 0.05 ].ConclusionButylphthalide can reduce the plasma enzyme activity,balance ET and CGRP,extend the cerebral arteries to antagonize ET,improve cerebral ischemia and cerebral hypoxia,which can protect brain cells and endothelial cells.

Objective To explore associations between SG13S114A/T and SG13S32A/C polymorphisms of ALOX5AP gene and the genetic susceptibility of ischemic cerebrovascular diseases (ICVD) in Henan Han population.Methods Two hundred and forty-six ICVD patients and 245 healthy controls were recruited from Han population in Henan province. Polymorphisms of SG13S114A/T and SG13S32A/C in ALOX5AP gene were genotyped in these samples by SnaPshot minisequencing method.Each genotype frequency and allele frequency were statistically analyzed and compared between ICVD group and control group using SPSS16.0 software.Haplotype and linkage disequilibrium were analyzed by SHEsis software.Results The SG13S114 AA genotype frequency ( 18.7％ ) and A allele frequency (41.3％) in ICVD group were significantly higher than those in control group (9.0％ and 32.7％,respectively; P =0.002 and P =0.005 ).It was also found that in male ICVD group and in younger ICVD group ( ＜50 years old),the SG13S114 AA genotype frequencies (22.1％ and 22.0％,respectively) and A allele frequencies (42.1％ and 42.7％,respectively) were significantly higher than those in male control group and younger control group (SG13S114 AA genotype:9.0％ and 8.9％ ; P =0.010 and P =0.006,respectively) ;A allele frequencies,34.0％ and 32.0％ ; P =0.048 and P =0.020,respectively.Finally,the prevalence of A-A haplotype in ICVD group was significantly higher than that in control group(30.4％ vs 23.5％,OR =1.419,95％ CI 1.068-1.885,P =0.015).T-C haplotype frequency of ICVD group was significantly lower than that in control group (22.0％ vs 28.8％,OR =0.698,95％ CI 0.523-0.932,P =0.014 ).Conclusions The A allele in SG13S114 loci of ALOX5AP may be a genetic risk factor for ICVD in Han population in Henan province.The association is predominant in ICVD patients of male and younger than 50 years old.Maybe A-A haplotype increases the risk of ICVD and T-C haplotype and has a protective effect against ICVD in Henan Han population.

Objective To investigate the effect of exercise prescription on foot perfusion and ulcer healing in patients with diabetic foot ulcer (DFU) accompanied with peripheral arterial disease (PAD).Methods Sixty patients with DFU and PAD were divided into exercise group and control group.The patients in the exercise group took exercise therapy training,ensuring that they could follow the exercise prescription.The patients in the control group had no exercise requirements.After the treatment for 12 weeks,ankle brachial index (ABI),transcutaneous oxygen tension (TcPO2),skin temperature,body mass index (BMI),HbA1C,and the ulcer healing rate in the two groups were compared,the satisfaction and compliance in the exercise group were evaluated,and the adverse events of the treatment were recorded.Results After the treatment for 12 weeks,the ABI,TcPO2,and foot skin temperature in the two groups increased and HbA1C decreased(P＜0.05 or P＜0.01).TcPO2 increased 5.25 mm Hg(1 mm Hg=0.133kPa),skin temperature increased 0.45℃,and BMI decreased 0.69 kg/m2 in the exercise group,while TcPO2 increased 2.59 mm Hg,skin temperature increased 0.28℃,and BMI increased 0.02 kg/m2 in the control group,showing significant differences in the three index changes between two groups (P＜0.01).The healing rate in the exercise group was higher than that in the control group (53.6％ vs 25.9％,P ＜0.05).The patients'compliance and satisfaction to the exercise therapy were 90％ and 94％,respectively.The incidence of adverse events in the exercise group had no causal relationship with the exercise prescription.Conclusion The exercise prescription in the study can improve the foot perfusion,and promote ulcer healing.It has the advantage of high safety,patients'compliance and satisfaction.

Objective To investigate the role of TNSALP gene detection in prenatal diagnosis of HPP. Method The clinical data and the results of complete exon sequencing of TNSALP gene in one neonate with low alkaline phosphatase (HPP) were analyzed retrospectively. Peripheral bloods from his family members were collected. The amniotic fluid cell in fetuses at 17 weeks was tested for candidate gene mutations by Sanger sequencing. Results Mainly manifestations in 6-day-old baby were multiple fractures, limb shortening and bending and dyspnea. He died of respiratory failure 9 days after birth. The serum alkaline phosphatase was decreased and serum calcium was decreased slightly; serum phosphorus, serum 25 hydroxyvitamin-D and parathyroid hormone were normal. X-ray showed that the whole body bone was very poorly mineralized, and the long diaphysis was enlarged with shape of a cup at the end and multiple fractures existed. Gene sequencing revealed a complex heterozygous missense mutation in the TNSALP gene, including the heterozygous missense mutation c.542C>T in exon sixth causing 181st amino acids changed from serine to leucine (p.S181L), and tenth exon heterozygous missense mutation in c.1016G>A causing 339th amino acid changed from glycine to glutamic acid (p.G339E). The parental phenotypes were normal. The c.542C>T mutation is inherited from his father and the c.1016G>A mutation is inherited from his mother. These two mutations were not detected in the fetus. Conclusion TNSALP gene analysis can be applied to the diagnosis and prenatal diagnosis of HPP.

Objective Using single direction dispersion breathless DWI, to analyze the value of DWI for vertebral bone marrow infiltration in patients with acute leukemia (AL). MethodsForty-two patients with AL and 15 healthy volunteers received vertebral sagittal DWI with single shot spin-echo echoplan imaging (SS-SE-EPI) sequence( b value ＝ 0,650 s/mm2) at a GE Signa Excite 1. 5 T scanner with 8 channels body coil. DWI for all patients were performed from three directions, including from superior to inferior (S/I), from anterior to posterior (A/P) and from right to left (R/L). The apparent diffusion coefficient (ADC) value was measured on ADC map from each direction using GE-Function tool DWI software. Forty two patients consisted of 13 onset with untreated patients and 29 treated patients (7 nonremission,8 complete remission and 14 consolidation therapy). The ADC values among the three diffusion directions were compared. Analysis of variance and t test were used to compare the ADC values in different AL stages, Pearson correlation analysis was used to analyze the correlation between ADC values and the percentage of bone marrow progenitor cells. Results The ADC values from S/I, A/P and R/L of 362 vertebras in the 57 subjects are (0. 758 ±0. 009) × 10-3 mm2/s, (0. 732 ±0. 009) × 10 -3 mm2/s and (0. 758 ±0. 009) × 10 -3 mm2/s, respectively. There is no statistical significance( F ＝ 2. 958, P ＞ 0. 05 ).The ADC values from S/I of 94 vertebras in 15 healthy volunteers is (0. 697 ± 0. 122) × 10 -3 mm2/s, of 85 vertebras in 13 untreated AL patients is (0. 592 ±0. 071 ) × 10-3mm2/s. There is statistical significance between them ( t ＝ 2. 568, P ＜ 0. 05 ) ; The ADC value of 183 vertebras in 29 treated AL patients [ ( 0. 796 ±0. 225 ) × 10-3mm2/s]is higher than that in untreated patients with statistical significance (t ＝ -1. 332,P ＜0. 05). One hundred and forty vertebras in patients with complete remission and consolidation therapy were [ (0. 786 ±0. 184) × 10-3 mm2/s],and 43 vertebras in patients with non-remission(NR) [ (0. 804 ±0. 327 ) × 10 - 3 mm2/s], there was not statistical significance between them ( t ＝ - 0. 160, P ＞ 0. 05 ). The ADC values from S/I direction of untreated patients showed significant negative correlation with the proportion of the blast cell in the bone marrow ( median value 26. 4％. Min 7.9％, Max 48. 2％ ) ( r ＝- 0. 524, P ＜ 0. 05 ). ConclusionsDWI of vertebral bone marrow is isotropy. ADC value is a non-invasive and quantitative index for evaluating the pathogenetic condition of AL.

To investigate the modulation effects of breathing movement on cardiovascular system and to study the physiological coupling relationship between respiration and cardiovascular system, we designed a comprehensive testing system for cardiorespiratory interaction research. This system, comprising three parts, i. e. physiological signal conditioning unit, data acquisition and USB medical isolation unit, and a PC based program, can acquire multiple physiological data such as respiratory flow, rib cage and abdomen movement, electrocardiograph, artery pulse wave, cardiac sounds, skin temperature, and electromyography simultaneously under certain experimental protocols. Furthermore this system can be used in research on short-term cardiovascular variability by paced breathing. Preliminary experiments showed that this system could accurately record rib cage and abdomen movement under very low breathing rate, using respiratory inductive plethysmography to acquire respiration signal in direct-current coupling mode. After calibration, this system can be used to estimate ventilation non-intrusively and correctly. The PC based program can generate audio and visual biofeedback signal, and guide the volunteers to perform a slow and regular breathing. An experiment on healthy volunteers showed that this system was able to guide the volunteers to do slow breathing effectively and simultaneously record multiple physiological data during the experiments. Signal processing techniques were used for off-line data analysis, such as non-invasive ventilation calibration, QRS complex wave detection, and respiratory sinus arrhythmia and pulse wave transit time calculation. The experiment result showed that the modulation effect on RR interval, respiratory sinus arrhythmia (RSA), pulse wave transit time (PWTT) by respiration would get stronger with the going of the slow and regular breathing.

Objective To evaluate the surgical complications and root vascular lymph node dissection by high versus low ligation the inferior mesenteric artery (IMA) retaining left colonic artery (LCA) in laparoscopic radical resection of rectal cancer.Methods Clinical data of 357 cases of rectal cancer in our center from Jan 2015 to Dec 2016,were retrospectively analyzed,including 247 cases in high ligation group,110 cases of low ligation group.Results There was no statistically significant difference in operative time and intraoperative blood loss between the two groups [(105 ± 10)min vs.(113 ±9)min,t =0.138,P =0.092;(96 ± 21) ml vs.(99 ± 23) ml,t =0.171,P =0.118].Nor that in the incidence of anastomotic leakage between the two groups (7.3％ vs.4.5％,x2 =0.949,P =0.330).The incidence of low anterior resection syndrome in the two groups was statistically significant (21％ vs.12％,x2 =4.358,P =0.037).There was no significant difference in the total number of lymph nodes dissected between the two groups ([(14.5±4.3) vs.(13.6±3.5),t=1.851,P=0.065].Conclusion Low ligation of IMA with preservation of LCA in laparoscopic radical operation for rectal cancer provides better blood supply for proximal colon,while achieving same radical clearance of lymph nodes as with high ligation of IMA.

Objective:To analyze the characteristics of sleep disordered breathing (SDB) in children with allergic rhinitis (AR), and improve the diagnosis and treatment at AR combined with obstructive sleep apnea (OSA).Methods:The clinical data of 120 patients with AR and OSA (AR and OSA group) admitted to the respiratory department at Shenzhen Children′s Hospital from May 2019 to December 2020 were retrospectively analyzed.A total of 120 children diagnosed with OSA and excluded AR during the same period were selected as control group.The SDB day and night symptoms, sleep structure characteristics and sleep breathing events were compared between two groups.Results:The average course of disease in children with AR and OSA was significantly longer than that in control group ( P=0.030). The main manifestations of children in AR and OSA group were mouth breathing (100.0%), snoring (99.2%), nasal obstruction (88.5%), and restless sleep (68.0%). There was no significant difference in sleep structure between two groups ( P>0.05), but the sleep efficiency of AR and OSA group was significantly lower than that of control group ( P=0.028). The respiratory events apnea hypopnea index, obstructive apnea index, obstructive apnea hypopnea index, hypopnea index and oxygen desaturation index of each sleep period in AR and OSA group were significantly higher than those in control group ( P<0.05). Among the children in AR and OSA group, moderate and severe OSA were the main manifestations, and the difference between two groups was statistically significant ( P<0.001). Conclusion:The combination of AR delayed the course of OSA in children.The main characteristics of sleep disordered breathing in children with AR are mouth opening, restless sleep, snoring and nasal obstruction.The sleep efficiency is decreased.Obstructive hypopnea and apnea are the most common respiratory events, and oxygen deficiency often occurs in rapid eye movement phase.Children with AR are more likely to have moderate or severe obstructive sleep apnea.
