Objective To evaluate the clinical effectiveness of the treatment for the intramedullary broad dissemination of the malignant bone tumor of limbs by microwave heliotherapy combined with prosthesis replacement.Methods From June 2001 to April 2012,19 patients with intramedullary broad dissemination of malignant bone tumor of limbs were treated with microwave heliotherapy combined with prosthesis replacement.There were 12 males and 7 females,47 years old on the average (ranging from 11 to 65 years).The tumors involved:primary malignant tumor 11 cases,metastases of the scapula 8 cases.Locations of tumors involved:the distal femur 8 cases,the proximal tibia 6 cases,the proximal humerus 3 cases and the proximal femur 2 cases.After the patients were examined with MRI and the level of osteotomy was determined,the prostheses were custom-made.The exposures of the all tumors were via the conventional surgical approach.The lesions were heated at 50 ℃ for 20 min by 2 450 MHz microwave,with surrounding soft tissue protected by copper mesh.The level of osteotomy was determined by the result of preoperative imaging measurement.The prosthesis was installed after the microwave heliotherapy.Results The duration of surgery was from 60 min to 150 min (100 min on average).The blood loss was from 300 ml to 1200ml (600 ml on average).All patients were followed-up for 10 months to 5 years (2.7 years on average).1 case with chondrosarcoma relapsed 18 months after surgery,and survived with tumors.1 case with malignant fibrous histiocytoma died due to multiple metastases 8 months after surgery.1 case with Ewing sarcoma died due to pulmonary metastases 23 months after surgery.The remaining 7 cases with the primary malignant bone tumors did not recur or transfer during the follow-up period.6 cases with the metastases died due to metastases 5 to 20 months after surgery.The functions of shoulder joint of 3 proximal humerus tumor patients were restricted,while 16 patient's function weren't restricted.Conclusion The clinical results demonstrated that the microwave heliotherapy combined with prosthesis replacement was an ideal treatment for the intramedullary broad dissemination of the malignant bone tumor of limbs.

To observe the clinical efficacy of combined acupuncture and Tuina in the treatment of enuresis following occult cleft spine and seek quantified indexes for result assessment, 40 subjects were treated by above methods and B-ultrasonically examined before and after treatment to determine the capacity of bladder and the residual urine inside it. The total effective rate was 90%; there was a difference of the capacity of bladder between before and after treatment (P＜0.05); 11 cases suffered from residual urine, and there was also significant difference of residual urine between before and after treatment (P＜0.01). It is revealed that this method can increase the capacity of bladder and diminish residual urine.

Abstract: Objective　To detect the antibody levels of hantavirus in serum samples from patients suspected with hemorrhagic fever with renal syndrome (HFRS) in Heilongjiang Province from 2019 to 2021, and to provide scientific basis for the prevention and control of disease. Methods　Enzyme-linked immunosorbent assays (ELISA) were used to detect the IgM antibodies to hantavirus in serum samples collected from suspected patients with HFRS in the acute-phase, and IgM and IgG antibody in convalescent-phase serum samples. The positive rate of IgM antibody in acute-phase serum samples of patients in different years was analyzed with χ2 test by SPSS 19.0, and the data were sorted out and analyzed about patients' gender, occupation, age, date of onset and interval from onset to initial diagnosis by EpiData 3.1, Excel 2003 software. Results　A total of 351 acute-phase serum samples and 208 convalescent-phase serum samples were detected in patients suspected with HFRS, respectively. There were 317 positive IgM antibodies of serum samples in the acute stage, with the positive rate of 90.31%. There was no significant difference in the positive rate of IgM antibodies in the acute stage between different years (χ2=0.895, P=0.639). T The IgM antibodies and IgG antibodies were positive in 32 (15.39%) and 28 (13.46%) of the convalescent-phase serum samples, respectively. Moreover, 148 patients (71.15%) were double-positive for IgM and IgG antibodies at the convalescent stage. The ratio of male to female patients was 4.56∶1, for which male patients were much more than female patients. Occupation was dominated by farmers (253 cases, 79.81%), followed by workers (19 cases, 5.99%) and the unemployed (17 cases, 5.36%), respectively. The age of patients ranged from 10 to 88 years old, with a median age of 49 years old. Most of the patients were in the age group from 30 years old to 60 years old (209 cases, 65.93%), among which the age group from 40 years old to 50 years old (86 cases, 27.13%) had the highest proportion, and the age group from 60 years old to 90 years old had a proportion of 20.18% (19 cases). May and November were the peak periods of HFRS in Heilongjiang Province. The median interval between onset and initial diagnosis was 4 days. Conclusions　There is a gap of about 10% between the clinical diagnosis of HFRS cases and the confirmed cases detected by laboratory in Heilongjiang Province from 2019 to 2021. The virus-specific detection results are important for confirming the diagnosis of local patients with HFRS.

Diabetic peripheral neuropathy (DPN), one of the most common chronic complications of diabetes, is characterized by allodynia, hyperalgesia and spontaneous pain. Chinese epidemiological studies have shown that at least 25% diabetic patients suffered from painful DPN, which compromises patients' daily functioning and becomes a major health care problem. Although the pathogenesis of painful DPN is not fully understood and current treatment options are very limited, research in the field has advanced our understanding on the mechanism of painful DPN in the past Decade of Pain Research and Control. This review will mainly focus on evaluation of current diabetic animal models, possible molecular pathways and available therapies, with an emphasis on roles of purinergic receptor and its signaling transduction pathways. Common therapies address one or two DPN symptoms, while others offer wider symptom control, presumably by targeting pathophysiological mechanisms of DPN. Purinergic receptor signaling transduction pathways might become potential targets for treatment for painful DPN.

OBJECTIVETo investigate the relationship between Arg778Leu/Gln gene mutation spot in ATP7B and TCM Syndrome type in Chinese patients with Wilson disease (WD).

METHODSExon 8 of ATP7B of 90 WD patients and 30 healthy controls were amplified by PCR and analysed by restriction enzyme Msp I, the TCM Syndrome type of the patients was differentiated at the same time.

RESULTSIn the 90 WD patients, 34 with Arg778Leu/Gln of exon 8 were detected, among them 20 cases belonged to the TCM Syndrome type of endogenous Liver-Wind agitation.

CONCLUSIONOnset age of WD patients with Arg778Leu/Gln mutation is later than that without this mutation. Arg778Leu/Gln mutation might be related to the TCM Syndrome type of endogenous Liver-Wind agitation.
