ABSTRACT
Objective:To explore the relationship between sleep status and the disease in children with recurrent vertigo(RVC) by analyzing the objective sleep condition of children with recurrent vertigo. Methods:According to the diagnostic criteria of RVC, 50 children with RVC and 20 normal controls without RVC were selected. According to the vertigo questionnaire score, the RVC group was divided into mild, moderate and severe groups according to severity. Continuous polysomnography(PSG) was performed for all participants, and SPSS 25.0 statistical software was used to analyze the monitoring results. Results:①There were significant differences in sleep time of each period, total sleep time and sleep efficiency between RVC group and control group(P<0.05), but there was no significant difference in sleep latency(P>0.05). The specific manifestations were that the proportion of sleep time in N1 and N2 phases increased, the proportion of sleep time in N3 and REM phases decreased, the total sleep time and sleep efficiency decreased in RVC group. ②The abnormal rate of sleep apnea hypopnea index, that is, the proportion of AHI≥5 times/h and the abnormal rate of lowest blood oxygen saturation in RVC group were higher than those in normal control group. There was significant difference between the two groups(P<0.05). ③There were significant differences in the proportion of AHI≥5 times/h and lowest SpO2 among mild group, moderate group and severe group(P<0.05). ④There was no significant correlation between the degree of vertigo and the abnormal rate of AHI in children with RVC, but there was a negative correlation between the degree of vertigo and the abnormal rate of lowest SpO2 in children with RVC. Conclusion:Children with RVC are often accompanied by sleep disorders, clinicians should pay attention to both the symptoms of vertigo and sleep condition in children. Polysomnography is non-invasive and operable, providing a new idea to the auxiliary examination of RVC in children. It is of certain clinical significance for the comprehensive treatment of children with RVC to actively improve vertigo symptoms and pay attention to improving sleep quality.

<p><b>OBJECTIVE</b>To compare the difference in the clinical therapeutic effects on mild and moderate lumbar disc herniation (LDH) of blood stagnation syndrome between-conducting needling technique at the governor vessel acupoints combined with electroacupuncture (EA) and conventional EA.</p><p><b>METHODS</b>Two hundred and one patients of LDH at the mild and moderate stage, differentiated as blood stagnation syndrome were randomized into an observation group (101 cases) and a control group (100 cases). In the observation group, the-conducting needling technique at the governor vessel acupoints and EA were used. The acupoints were Yaoyangguan (GV 3), Shiqizhui (EX-B 8), Huantiao (GB 30) and Yanglingquan (GB 34). Afterarrival, the-conducting needling technique was used at Yaoyangguan (GV 3) and Shiqizhui (EX-B 8); the EA was at Huantiao (GB 30) and Yanglingquan (GB 34). The treatment was given once every two days, 3 times a week. The treatment for 12 times was as one session. The observation lasted for 1 session. In the control group, the acupoints were the same as the observation group and stimulated with EA. The EA parameters, treatment frequency and duration were all the same as the observation group. The lumbar back pain score of Japanese Orthopedics Association (JOA) score before treatment, after treatment and in 3-month follow-up visit in the two groups, the infrared thermogram temperature in lumbar region and the relaxation area under curve (RAUC) before and after treatment as well as the short-term and the long-term therapeutic effects were compared between the two groups.</p><p><b>RESULTS</b>The total short-term effective rate was 89.11% (90/101) and the total long-term effective rate was 91.11% (82/90) in the observation group, and those were 86.00% (86/100) and 89.53% (77/86) in the control group respectively, without significant differences between the groups (both>0.05). The short-term clinical curative rate was 52.48% (53/101) and the long-term clinical curative rate was 55.56% (50/90) in the observation group, better than 36.00% (36/100) and 34.88% (30/86) in the control group (both<0.05).

Objective To observe the correlation of MRI findings with treatment outcome of percutaneous kyphoplasty (PKP) in the acute phase of osteoporotic vertebral compression fracture (OVCF).Methods A total of 101 patients with single-segment OVCF undergone PKP in the acute phase were included in the study.There were 19 males and 82 females, at age range of 61 to 89 years (mean, 69.3 years).According to the T2WI signal intensity, the patients were divided into low signal group (Group A), low-medium signal group (Group B), medium signal group (Group C), and mediumhigh signal group (Group D).visual analogue scale (VAS) was used to evaluating the pain relief.Correlations of MRI signal with vertebral height, vertebral compression ratio, Cobb's angle change in each group were determined.Results All MRI images were shown as low signal in T1WI and high signal in FS-T2WI.On the T2WI images, the signal was medium-high in 14 vertebrae, medium in 18 vertebrae, low-medium in 31 vertebrae, and low in 38 vertebrae.Among four groups, the VAS score, vertebral body height, vertebral compression ratio and Cobb's angle changes before operation showed no statistical difference compared with those after operation (P < 0.05).Conclusions MRI findings are primarily low or medium signal on T2WI images in the acute phase of OVCF, which shows insignificant correlation with effect of PKP.However, PKP is effective in the treatment of OVCF.
ABSTRACT
Background:Intestinal metaplasia(IM)and dysplasia in Barrett’s esophagus(BE)can be detected by endoscopic biopsy combined with pathological examination. Aims:To evaluate the efficacy of acetic acid stain-guided biopsies in detection of IM and dysplasia in BE under standard endoscopy. Methods:One hundred patients found to have columnar-lined esophagus by endoscopy from January 2012 to November 2014 at Shanghai Jing’an District Central Hospital were enrolled. Under standard endoscopy,acetic acid was sprayed and multi-point biopsies were performed in visible abnormal regions. This was followed by four-quadrant biopsies at every 1 to 2 cm of the remaining BE segments. Detection rates of columnar epithelium,IM and dysplasia were compared between acetic acid stain-guided biopsies and four-quadrant biopsies. Results:A total of 96 patients were diagnosed as BE. Detection rates of columnar epithelium by acetic acid stain-guided biopsies and four-quadrant biopsies were 96. 9%(93 / 96)and 90. 6% (87 / 96),respectively,no significant difference was found between the two methods(McNemar test,P = 0. 146),however,consistency of the two methods was poor(κ = 0. 340). A total of 32 patients were diagnosed as BE with IM. Detection rates of IM by acetic acid stain-guided biopsies and four-quadrant biopsies were 84. 4%(27 / 32)and 40. 6%(13 / 32),respectively,difference in detection rate between the two methods was significant(McNemar test,P = 0. 007),and consistency of the two methods was poor(κ =0. 266). Five cases of low-grade dysplasia were detected by acetic acid stain-guided biopsies only. Conclusions:Acetic acid stain-guided biopsies can detect BE with IM and dysplasia better than four-quadrant biopsies.
ABSTRACT
Objective To evaluate the short-term and long-term therapeutic efficacies of LU’s heat-producing needling (Shao Shan Huo) in treating cervical spondylotic radiculopathy (CSR). MethodTwo hundred patients with CSR were randomized into a treatment group and a control group, 100 in each group. The treatment group was intervened by using heat-producing needling method, while the control group was by regular acupuncture technique with even reinforcing-reducing manipulations. For both groups, the treatment was given once a day, 10 sessions as a treatment course. The Pain Rating Index (PRI), Present Pain Intensity (PPI), and Visual Analogue Scale (VAS) were adopted for observation before intervention and after two treatment courses. The clinical efficacies were compared between the two groups.Result Right after the intervention and in the 3-month follow-up, the VAS, PPI, and PRI scores were significantly different from that before intervention in both groups (P<0.01). There were significant differences in comparing the VAS, PPI, and PRI scores between the two groups after intervention and in the 3-month follow-up (P<0.01). The VAS, PPI, and PRI scores in the treatment group right after intervention were markedly different from that in the 3-month follow-up (P<0.01). The total effective rate was 98.0% in the treatment group versus 79.0% in the control group, and the difference was statistically significant (P<0.01).Conclusion LU’s heat-producing needling is an effective way in treating CSR, as it can significantly reduce pain intensity, and improve other symptoms and body signs.
ABSTRACT
Objective:To assess the efficacy and safety of electroacupuncture (EA) at Houxi (SI 3) in treating acute lumbar sprain. Methods: Randomized controlled trials (RCTs) involving EA at Houxi (SI 3) for acute lumbar sprain were retrieved from PubMed (1966-2014), EMBASE (1980-2014), Cochrane Library (Issue 1, 2014), CQVIP Database (1989-2014), Wanfang Digital Journal (1998-2014), the Chinese Biological Medical Literature Database (CBM, 1978-2014), and China National Knowledge Internet (CNKI, 1979-2014). The collection of data also adopted hand-search of the relevant journals from the Library of Shanghai Jiao Tong University. All of the data were first evaluated and extracted by two reviewers independently with a specially designed form. Then, the available data were analyzed by the Cochrane Collaboration's RevMan 5.2.0 software. Results:A total of 6 trials involving 1 288 patients were eligible. Meta-analysis showed that the total effectiveness rate in the EA group was significantly different when compared with Nimesulide [RR=1.33; 95% CI (1.19 to 1.49)] and Mobic [RR=1.08; 95% CI (1.03 to 1.14)], but similar to that of acupuncture at Yaotongdian (EX-UE 7) [RR=71.09; 95% CI (1.00 to 1.19)] and Diclofenac Sodium [RR=1.08; (95% CI 0.96 to 1.21)]. The recovery rate in the EA group was significantly different when compared with Mobic [RR=1.67; (95% CI 1.45 to 1.92)] and Nimesulid [RR=1.37; (95% CI 1.15 to 1.62)], but similar to that of acupuncture at Yaotongdian [(RR=1.35; 95% CI 0.99 to 1.84)] and Diclofenac Sodium [(RR=1.19; 95% CI 0.88 to 1.61)]. Conclusion:Up to the search date, there are few high quality RCTs to evaluate the clinical efficacy of EA at Houxi (SI 3) for acute lumbar sprain, especially studies in English. Yet EA at Houxi (SI 3) still appeared to be an efficacious method for acute lumbar sprain, despite several inherent defects of the included studies. Further large scale trials are required to define the role of EA at Houxi (SI 3) in the treatment of this disease.

BACKGROUND: Studies have shown that acupuncture combined with Chinese medicine has a certain effect in the treatment of knee osteoarthritis. OBJECTIVE: To investigate the mechanism and effect of acupuncture combined with Chinese medicine for the treatment of knee osteoarthritis. METHODS: The animal models of knee osteoarthritis were established to detect the expression levels of related factors, including matrix metal oproteinase 3, transforming growth factor β, interleukin-1β and tumor necrosis factor-α. The knee osteoarthritis patients treated with acupuncture combined with Chinese medicine were fol owed-up, and the patients received acupuncture in the main points and the adjunct points, as wel as the Chinese medicine administration and the external application and fumigation. Then, the active function recovery of the knee joint was observed to identify the effect of acupuncture combined with Chinese medicine. RESUTLS AND CONCLUSION: Acupuncture can delay the destruction of knee joint articular cartilage and improve the knee function through decreasing the contents of matrix metal oproteinase 3, transforming growth factor β, interleukin-1β and tumor necrosis factor-α, thus playing the treatment effect on knee osteoarthritis. The knee osteoarthritis patients treated with acupuncture combined with Chinese medicine can obtain better effect, and the treatment efficiency is more than 90%. Compared with the single application of sodium hyaluronate or acupuncture treatment, acupuncture combined with Chinese medicine has higher treatment efficiency and better treatment effect.
ABSTRACT
Objectives To study the mutation spectrum in CYP21A2 gene in patients with 21-hydroxylase deficiency (21-OHD), and to analyze the relationship between genotype and phenotype. Methods Eighteen patients with 21-OHD were identified by neonatal screening of 17α-OH progesterone (17α-OHP). The allele specific PCR-DNA sequencing com-bining with multiplex ligation-dependent probe amplification was applied to determine the genotype in the patients and their parents. Results Six mutations of CYP21A2 gene were identified. I2G (44.4%) and del (33.3%) were the most frequent mutations and also were the most common mutations in salt-wasting form. The detection rate of I172N mutation in simple virilizing form was 75%. Patients were classified into three groups according to the degree of 21-hydroxylase enzymatic compromise caused by the mutation. The serum 17α-OHP, ACTH and T levels which reflected the severity of disease were significantly different among three groups (P<0.05). Conclusions The genetic diagnosis of 21-OHD reveals the consistency between genotype and phenotype.
ABSTRACT
Objective To approach the efficiency of second-trimester prenatal screening using two serum markers for Down's syndrome (DS).Methods Retrospective analysis was conducted on the results of prenatal screening using two serum markers,alpha fetoprotein (AFP) and free beta subunit of human chorionic gonadotropin(free-β-hCG),in 50 cases of DS pregnancy identified among 60 931 pregnant women received prenatal screening from November 1997 to April 2008 in Nanjing Maternal and Child Health Hospital.Results Among the 50 DS cases,the detection rate of DS was 50% (25/50) when taking free-β-hCG≥2.5 MoM as the cut-off,with the positive rate of screening was 6.6%.And the detection rate of DS would be 18.0%(9/25) when taking AFP≤0.5 MoM as the cut-off,with the positive rate of screening was 4.6%.When the risk cut-off value of DS was set at 1/270,the detection rate changed to 52.0%,and the positive rate of screening was 4.7%;and the two figures changed to 62.0% and 5.5%,respectively,when the risk cut-off was set to 1/300.Thirteen DS cases showed the risk value between 1/1000 and 1/300,among which two were monomarker abnormality.Thirteen (26.0%) of the 50 DS fetus were found to have one or two abnormality markers by ultrasound scan,among which one was DS low risk,and the other 12 were DS high risk in serum screening.Conclusions The second-trimester prenatal screening using AFP or free β-hCG for Down's syndrome is effective in identifying DS pregnancy with limited specificity and sensitivity.But the detection rate can be elevated by the combination of these two markers.The second trimester systemic ultrasound scan is not ideal for DS identification,but it can increase the specificity and sensitivity of serum prenatal screening.
ABSTRACT
Objective To evaluate whether the gastroesophageal reflux disease (GERD) questionnaire (GerdQ) symptom score could reflect the acid exposure indicated by 24-hour esophageal pH monitoring in patients with GERD, and to further validate the clinical application value of GerdQ.Methods From November 2008 to March 2010, 134 GERD patients from outpatient department with heartburn and acid reflux symptoms were enrolled.All the patients had undergone endoscopy examination, 24-hour esophageal pH monitoring and GerdQ scoring.According to 24-hour esophageal pH monitoring result, acid exposure group and none acid exposure group was divided by the percentage of time that pH was lower than 4 over 4.2% or DeMeester score over 14.72, the difference of GerdQ score was assessed.The receiver operating characteristic (ROC) curve of GerdQ score was drawn according to DeMeester score and the percentage of time that pH was lower than 4 as the gold standard.With SPSS 17.0 statistical software, the ratio was compared with the u test and Chi-square test, comparison between groups with t test.Results The BMI of acid exposure group was higher than that of none acid exposure group(t= 2.365, P= 0.019).The GerdQ score of acid exposure group (8.51± 2.34) was significantly higher than that of none acid exposure group (6.67 ± 2.79), the difference was statistically significant (t = 4.002, P = 0.000) .ROC curve was drawn according to DeMeester score over 14.72 as gold standard; the area under curve (AUC) was 0.70.When the critical value of GerdQ score was 7.5, Youden index was up to 0.3365, the sensitivity of diagnosis was 0.6909 and specificity was 0.6454.The percentage of time that PH was lower than 4 over 4.2% as the gold standard, the AUC of GerdQ score was 0.663.When the critical value of GerdQ score was 7.5, Youden index was up to 0.2790, the sensitivity of diagnosis was 0.6600 and specificity was 0.6190.Conclusions GerdQ score greater than 7.5 can better reflect acid exposure at the lower esophageal.There is stronger association between GerdQ score with the DeMeester acid exposure score over 14.72 than with the percentage of time that pH lower than 4 over 4.2% as the critical value for acid exposure.Obesity may aggravate the transient lower esophageal sphincter relaxation leading to occurrence of GERD symptoms.
ABSTRACT
BACKGROUND: Electro-acupuncture therapy shows good central and peripheral analgesic effects. Several studies have shown that transforming growth factor β (TGF-β) plays an important role in the pathogenesis of knee osteoarthritis. OBJECTIVE: To investigate the mechanism underlying electro-acupuncture treatment of knee osteoarthritis. METHODS: A total of 80 healthy male 3-month-old Sprague Dawley rats were randomly and evenly divided into normal, model, electro-acupuncture and drug groups. Rat models of knee osteoarthris were estbalished by ligating the femoral veins and forcing rats to do activies. At 1 month after knee osteoarthris induction, the electro-acupuncture group rats received electro-acupuncture therapy at two acupoints Neixiyan (EX-LE4) and Dubi (ST 35) with a depth of 0.1 cun (pulse 2 Hz, 20 minutes, once a day). The drug group rats were intraarticularly administerd sodium hyaluronate (0.1 mL/administration, once a week). After 2-week treatment, synovial tissue of the knee joint was harvested to determine the exprssion of TGF-β1, TGF-β1 receptor Ⅰand TGF-β1 receptor Ⅱ. RESULTS AND CONCLUSION: TGF-β1 expression in synovial tissue of the knee joint was significantly increased after knee osteoarthris (P < 0.05), but after electro-accupuncture therepy or sodium hyaluronate treatment, TGF-β1 expression was significantly decreased (P < 0.05), moreover, TGF-β1 receptor Ⅰ, Ⅱ expression was signficantly decreased (P < 0.05). These findings suggest that electro-acupuncture for treatment of knee osteoartheis improves the symptoms of osteoarthris by downregulating TGF-β1 expression, and reduction in TGF-β1 receptor Ⅰ, Ⅱ expression promotes the recovery of knee osteoarthris.
