OBJECTIVETo explore the correlation between anti-sperm antibody-positive immune infertility patients and human leucocyte antigen (HLA) DQA1 gene, and to study the correlation between the treatment of Chinese medicine and pharmacy and HLA-DQA1 genotype.

METHODSThe polymerase chain reaction-sequence specific primers (PCR-SSP) technique was used in studying HLA-DQA1 genotypes of 51 anti-sperm antibody-positive immune infertility patients and 60 healthy subjects. Mianbu III (consisting of rehmannia root, white peony root, Fructus Comi, yam, barbary wolfberry fruit, moutan bark, and dwarf lilyturf root) was used in patients for three months.

RESULTSThe HLA-DQA1 *0401 allele in the immune infertility group was obviously higher than that in the healthy control group (chi2 = 29.869, P < 0.01). As for the therapeutic efficacy 22 cases of the 27 positive HLA-DQA1 * 0401 turned to negative with statistical difference (chi2 = 5.24, P = 0.022).

CONCLUSIONHLA-DQA1 *0401 allele might be predisposing gene of the anti-sperm antibody-positive immune infertility. The Chinese medicinal treatment was effective for the HLA-DQA1 *0401 allele patients.

Abstract: Objective　To analyze the epidemiological characteristics of public health emergencies in Xishuangbanna Dai Autonomous Prefecture from 2012 to 2021, and to provide reference for formulating relevant prevention and control measures. Methods　The data of public health emergencies reported in Xishuangbanna from 2012 to 2021 were collected and analyzed through the China Disease Prevention and Control Information System. Results A total of 78 public health emergencies (including "Unrated" events) were reported in Xishuangbanna from 2012 to 2021. The highest 21 cases and the lowest 3 cases were reported every year. A total of 1 0374 cases were reported in 78 public health emergencies, involving a population of 1 703 049, with a morbidity of 609.14/100 000, 24 deaths, mortality of 1.41/100 000 and fatality rate of 231.35/100 000. The event level was mainly "general (level Ⅳ)" with 52 incidents, accounting for 66.67%, and 17 incidents of "major (level Ⅲ)", accounting for 21.79%. 51 cases were mainly infectious diseases, accounting for 65.39%. The peak periods for incidents were May-July and November-February of the next year; there were 39 incidents in schools, accounting for 50%, followed by 20 incidents in families, accounting for 25.64%. The top three reported cases were food poisoning (32.05%), chicken pox 17 (21.79%) and dengue fever 10 (12.82%). Among the 24 deaths in public health emergencies, 22 were caused by food poisoning. Wild bacteria poisoning and alcohol poisoning were the main causes of food poisoning, accounting for 45.83% and 37.5% of the total deaths, respectively. Conclusion Infectious diseases, especially respiratory diseases and food poisoning are the focus of the prevention and control of public health emergencies in Xishuangbanna Dai Autonomous Prefecture, of which Schools and families should be pay close attention. Plague, a Class A infectious disease, caused by the bacterium Yersinia pestis has occurred in two inter-animal outbreaks in 10 years and spread to the population, which should be of great concern.

ABSTRACT:Objective To compare the clinical effects of Zero-P and traditional titanium plate with cage in treating single level cervical spondylosis.Methods We retrospectively analyzed the clinical data of 28 patients with single level cervical spondylosis who underwent anterior cervical discectomy and fusion (ACDF)by traditional titanium plate with cage (group A,n=16)or Zero-P implant (group B,n=16)in our department between January 2012 and January 2014.The intraoperative blood loss,operation time,postoperative JOA scores,JOA recovery rate,NDI scores,and dysphagia incidence in both groups were measured and compared.The changes of the midpoint interbody height (IBH),the cervical Cobb angle of the surgical segment and the cervical Cobb angle of C2 and C7 vertebral body were measured on the standing lateral cervical spine X-ray.Results The operation time was significantly longer in group A than in group B (P < 0 .0 1 ), but there were no significant differences in intraoperative blood loss between the two groups (P>0 .0 5 ).The incidence of dysphagia was lower in group B than in group A.The two groups did not significantly differ in JOA score or JOA improvement rate during the same period after operation (P>0.05).The NDI score in group B was significantly lower than that in group A (P<0 .0 5 )at 1 month and 6 months after operation,but showed no significant difference in preoperative and 1 2 months after operation (P>0 .0 5 ).The midpoint interbody height in group B was significantly greater than that in group A (P<0 .0 5 )1 2 months after operation,but showed no significant difference one month after operation.The cervical Cobb angle of the surgical segment was significantly greater in group B than in group A (P<0 .0 5 )after operation, but there was no significant difference in cervical Cobb angle of C2 and C7 vertebral body between the two groups at various time points (P>0.05).Conclusion Zero-p and traditional titanium plate with cage have similar effects in treating single level cervical spondylotic myelopathy,and Zero-P system has the advantages of lower incidence of dysphagia after operation,shorter operation time and better recovery of postoperative cervical physiological structure.

Objective: We present our preliminary experience of using a homemade transumbilical single-port access for performing transumbilical single port access (SPA) laparoscopic surgery for gastrointestinal disease and its perioperative nutritional management.Methods: During Nov.2009-Dec.2009,five patients received SPA surgery and nutritional management following the protocol of fast track surgery.A patient with stomach GIST received partial gastrectomy,a patient with ascending colon lymphoma received right hemicolectomy,a patient with rectal cancer received anterior resection,a patient with jejunum GIST received partial small bowel resection,and a patient with early gastric cancer received distal subtotal gastrectomy (D1+α). Results: Transumbilical SPA surgery were successfully done in five patients without conversion.The mean length of incision was 3 cm,the mean time for operation was 138 (60-240)min,and the mean blood loss was 50 (10-100)ml.All patients could mobilize and orally drink on the 1st day after operation,have soft diet the 3st days after operation,their mean postoperative hospital stay was 4 days.No complication occurred.Mean body weight loss was 2.6 kg on discharge compared with at admission.Conclusion: Transumbilical SPA surgery with the protocol of fast-track surgery had advantages including shorter incision,less trauma,faster recovery,and less body weight loss.

Objective To compare the modified expanding suspended laminoplasty and posterior pedicle screw fixation applied in lumbar intraspinal tumors and evaluate operation,complications,postoperative neurofunctional improvement and lumbar lumbar stability in the two groups.Methods We made a retrospective analysis of the clinical data of 1 14 cases of lumbar intraspinal tumors, including 66 cases of modified expanding suspended laminoplasty and 48 cases of posterior pedicle screw fixation.We compared the operation time,operation bleeding volume,and incidence of postoperative cerebrospinal fluid leakage in the two groups.We also analyzed the lumbar instability and spinal cord injury score standard by the Japanese Orthopedic Association (JOA)between the two groups at 3,6, 12,and 24 months after operation.Results The results of modified expanding suspended laminoplasty group were significantly better than those of posterior pedicle screw fixation group in operation time, operation bleeding volume and incidence of postoperative cerebrospinal fluid leakage (P < 0.01 ).The lumbar instability did not significantly differ between the two groups (P >0.05).At 3,6 or 12 months after the operation, changes in the increase of JOA score of the two groups had no significant difference (P > 0.05 ).However,24 mouths after the operation,the group of posterior pedicle screw fixation had significantly improved JOA score compared with that in the modified expanding suspended laminoplasty group.Conclusion Both the modified expanding suspended laminoplasty and posterior pedicle screw fixation have a favorable outcome of postoperative lumbar instability and neurofunction.And posterior pedicle screw fixation is superior to modified expanding suspended laminoplasty in improving neurofunction.

Objective To investigate the indications,surgical principles and advantages and disadvantages of microsurgery of intra-spinal tumor via the quadrant pathway.Methods We made a retrospective analysis of the clinical data of patients with spinal canal tumors treated via the quadrant pathway from October 2014 to July 201 5. Results Totally 1 6 patients were included.Their tumors were fully removed by microscopic resection,in which there were three epidural cases,twelve subdural extra-medullar cases,and one intra-medullar case.In terms of stage,there were three cases of cervical segment (C3 - C7 ),four cases of thoracic (T1 - T10 ),nine cases of thoracic and lumbar ones (T1 1 - S2 ). In pathology, there were nine cases of neurilemmoma, two cases of neurofibroma,four cases of meningeal tumor and one case of neuroepithelial cyst.The postoperative symptoms and signs of the patients were significantly improved,and no recurrence or complications occurred in the follow-up 2-10 months.Conclusion Quadrant pathway can be used in removing spinal epidural and subdural tumor,which is shorter than two vertebral segments in length,and the cross-sectional area is less than 2/3 of the spinal cord. However,surgery with extensive adhesion and intra-medullary lesions should be performed carefully,and the surgical techniques are more demanding and a longer learning curve is needed.

Three primer were designed based on the consevered area of the genetic of the ATCC VR-2332 strain and LV strain. And the nest RT-PCR of testing porcine reproductive and respiratory syndrome virus were developed. The nest RT-PCR against ATCC VR-2332 strain, LV strain and B13 strain were done by this method.The DNA fragment were obtained specially from the three strains isolated from different region. The size were 430bp (430bp) , 410bp (413bp) and 410 bp (413bp) separately. But the DNA fragment were not obtained from HCV, PPV and PRV. Its sensitivity was 10-2 TCID50. It's sensitivity increased 10000 times than one step RT-PCR. It should make the method of testing porcine reproductive and respiratory syndrome virus more sensitive, fast and accurate.

OBJECTIVETo examine the growth-inhibitory, apoptosis- and necrosis-inducing effects of realgar nano-particles (RNP) in human chronic myelogenous leukemia cell line K562 and acute myeloid leukemia cell line HL-60, and to find out the chemical species with efficacy.

METHODA "solvent-relay" strategy was used for the preparation of RNP suspension. Cell viability was determined by MTT assay. Cell apoptosis and necrosis were characterized with Annexin V-PI double staining in association with flow cytometry and with morphological examination with Hoechst 33258 staining. Parallel experiments with arsenous acid (H3AsO3), the dominant form of arsenic trioxide in the solution, were conducted for comparison.

RESULTThe mean diameter of RNP was 159.0 nm. RNP showed growth-inhibitory effect on both cell lines. The double staining test indicated that RNP induced both apoptosis and necrosis, and this was further confirmed by morphological examination.

CONCLUSIONRNP induced both apoptosis and necrosis in leukemia cell lines K562 and HL-60. Thioarsenite species with both As-O and As-S bonds may be the active intermediates in the RNP.
