Effects of acupuncture plus spinal manipulations on physical functioning and biochemical indicators in patients with ankylosing spondylitis / 针灸推拿医学（英文版）

Objective: To observe the effects of acupuncture plus spinal manipulations on the physical functioning and levels of alkaline phosphatase (ALP), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and osteoprotegerin (OPG) in patients with ankylosing spondylitis (AS). Methods: A total of 128 AS cases were allocated into a control group and an observation group using random number table method, with 64 cases in each group. Patients in both groups took sulfasalazine and meloxicam. Patients in the observation group received additional acupuncture plus spinal manipulations. The efficacy, Bath AS functional index (BASFI), Bath AS disease activity index (BASDAI), and the levels of ALP, ESR, CRP and OPG were compared between the two groups after eight weeks of treatment. Results: After treatment, the symptom scores of traditional Chinese medicine in both groups were decreased (all P<0.05), and these scores in the observation group were significantly lower than in the control group (all P<0.05); the VAS, BASFI and BASDAI scores in both groups were decreased (all P<0.05), and these scores in the observation group were significantly lower than in the control group (all P<0.05); and the ALP, ESR, CRP and OPG levels in both groups were decreased (all P<0.05), and these levels in the observation group were significantly lower than in the control group (all P<0.05). The total efficacy rate was 92.2％ in the observation group, versus 78.1％ in the control group, presenting a statistical significance (P<0.05). Conclusion: Conventional medication combined with acupuncture and spinal manipulations can improve clinical symptoms, accelerate the recovery of physical functioning, and reduce the ALP, ESR, CRP and OPG levels.

Diagnosis and treatment of colorectal cancer by reduced port laparoscopic radical resection / 中华老年医学杂志

Objective@#To investigate the clinical efficacy of reduced port laparoscopic radical resection on colorectal cancer.@*Methods@#Clinical data of 46 patients with colorectal cancer undergoing reduced port laparoscopic radical resection were retrospectively analyzed.@*Results@#All of 46 patients underwent laparoscopic surgery, with an average operation time of 206 minutes, an average intraoperative bleeding of 56 ml, an average number of lymph nodes removement of 12/case (ranged from 6 to 21). One case had incision infection, 2 cases had anastomotic leakage, and they all recovered and discharged after treatment.@*Conclusions@#Reduced port laparoscopic radical resection of colorectal cancer is safe and feasible, reduces labor costs, and has a good clinical efficacy, which is worthy of clinical promotion.

Quantitative studies on SMN1 gene and carrier testing of spinal muscular atrophy / 中华医学遗传学杂志

<p><b>OBJECTIVE</b>To construct a method for detecting the copy number of survival of motor neuron 1 gene (SMN1) with single copy difference based on real-time fluorescence quantitative PCR, and to make practical use of the method for acquiring the data on SMN1 copy number in Chinese as well as for screening the carriers of spinal muscular atrophy (SMA) from healthy individuals and SMA families.</p><p><b>METHODS</b>Exon 7 and flanking area of SMN1 gene were amplified by real-time fluorescence quantitative PCR in 264 healthy individuals, in 1 standard sample having 2 SMN1 but having no SMN2, and in 88 parents of SMA patients. The samples for detecting were diluted to 30 ng/microL and the standard sample was diluted to 15 ng/microL, 30 ng/microL, 45 ng/microL, 60 ng/microL; the unknown samples and 4 standard samples with different concentrations were amplified at the same time, a standard curve could be drawn out according to the results of the 4 standard samples, then the copy number of samples could be calculated.</p><p><b>RESULTS</b>Of 88 parents' samples, 84 samples each had 1 copy of SMN1, and the rest 4 each had 2 copies of SMN1. Of 264 healthy individuals' samples, 5 samples each had only 1 copy of SMN1 (an indicator of definite gene carriers), 232 samples each had 2 copies of SMN1, 25 samples each had 3 copies of SMN1, and 2 samples each had 4 copies of SMN1. Of the samples of 32 members of SMA families, 2 samples each had only 1 copy of SMN1 indicating definite gene carriers, 25 samples each had 2 copies of SMN1, and 5 samples each had 3 copies of SMN1.</p><p><b>CONCLUSION</b>SMN1 copy number could be detected precisely by real-time fluorescence quantitative PCR; the screening of gene carriers could provide essential data for genetic counseling.</p>

Rapid diagnosis of spinal muscular atrophy using denaturing high-performance liquid chromatography / 中华医学遗传学杂志

<p><b>OBJECTIVE</b>To introduce the application of denaturing high-performance liquid chromatography (DHPLC) in the diagnosis of childhood type spinal muscular atrophy (SMA).</p><p><b>METHODS</b>Exon 7 and flanking area of survival motor neuron (SMN) gene were amplified by PCR in 1 standard sample, 25 normal individuals and 25 patients with SMA. The PCR products were then directly loaded onto the DHPLC system after denaturing and annealing. Different DNA segments were separated by changing the concentration of buffer A relative to that of buffer B.</p><p><b>RESULTS</b>Different DNA segments were separable on the DHPLC chromatogram. Three peaks including SMN1/SMN2 heteroduplex peak, SMN2 homoduplex peak and SMN1 homoduplex peak were detected in 23 out of 25 normal individuals. Only SMN1 homoduplex peak was detected in 2 normal individuals and the standard sample, indicating the deletion of SMN2 On the contrary, only the SMN2 homoduplex peak was detected in 22 out of 25 patients with SMA, indicating deletion of SMN1. The three peaks as those of normal individuals were detected in the other 3 patients, indicating no SMN1 or SMN2 deletion.</p><p><b>CONCLUSION</b>As a new technology for diagnosing SMA, DHPLC is sensitive, accurate, rapid and convenient.</p>
