Objective:To observe the clinical effects of electroacupuncture (EA) plus acuoint-injection for nerve root sciatica.
Methods:A total of 114 cases were randomly divided into an observation group and a control group, 57 cases in each group. The observation group was given EA plus acupoint-injection therapy with Cobamamide. The control group was given oral administration of Diclofenac Sodium Sustained-release Tablets plus muscular injection of Cobamamide. After one-course treatment, the clinical effects were compared between the two groups.
Results:The total effective rate was 96.5%in the observation group and 91.2%in the control group, without a statistical significance in the difference between the two groups (P>0.05). The curative rate was 57.9%in the observation group and 21.1% in the control group, with a statistical significance in the difference between the two groups (P<0.05). In the follow-up on the fourth day after the treatment, the recurrence rate was 23.1%in the observation group and 47.9%in the control group, with statistical difference between the two groups (P<0.05).
Conclusion: EA plus acupoint-injection therapy for sciatica of nerve roots is remarkable in the clinical effect and needs promotion in clinic.

Objective To explore radionuclide bone imaging characteristics of lung cancer patients and evaluate the clinical significance of bone imaging in the diagnosis of lung cancer patients with bone metastases.Methods One hundred and seventy-seven patients with diagnosed lung cancer were examined by 99mTc -MDP bone imaging,and the symptoms,sites,quantity and pathological types of bone metastases were reviewed and analyzed.Results Total bone metastases ratio of lung cancer was 45.8%(81/177),and 85.2 % (69/81) patients had multiple bone metastases.There was a statistical significance of bone metastases in adenocarcinoma patients (69.0%,40/58),compared with patients of other types of lung cancer[squamous cell cancer (41.3%,19/46),small cell cancer ( 32.5%,13/40),undifferentiated carcinoma ( 27.3%,9/33)](P<0.05).Bone metastases happened in 526 places: thoracic bones 212 places (40.3%),vertebras 168 places (31.9%),pelvic bones 73 places (13.9%),extremities 62 places (11.8%),and skull 11 places (2.1%).Conclusions Multiple bone metastases is more frequent in lung cancer patients.The most frequent metastatic sites are thoracic bones and vertebras.Bone metastases of adenocarcinoma is more easily than other types of lung cancer.All the patients with lung cancer should perform radionuclide bone scan,which is significant for staging,selecting therapy methods and the evaluating prognosis of the disease.

Objective To investigate the feasibility and technique of laparoscopic subtotal cholecystectomy(LSC).Methods Totally 168 patients were converted to LSC because of failure in laparoscopic cholecystectomy(LC).During the LSC,the Calot's triangle was separated and then the Hartmann's pouch was incised to decreased the intracystic pressure for the removal of the stones.Results Among the cases,5 patients were converted to open surgery for subtotal resection of the gallbladder.LSC was completed after clipping the cystic duct and artery in 122 patients;in the other 41 cases,the gallbladder was cut at the Hartmann's pouch to clip the bile duct and artery or suture the neck of the gallbladder,and then LSC was performed.The median operation time was(65.5?15.2)min,and the intraoperative blood loss was(71.5?15.5)ml.The time to resume the diet was(20.4?6.3)h postoperation.After the operation,7 patients developed local complications(4.2%),and the mean postoperative hospital stay was(4.2?2.6)d.Of the patients,105 were followed up for(25.5?6.5)months,during this period,5 patients had dyspepsia,3 had right shoulder pain,and 9 had right hypochondrium pain.Conclusions LSC is feasible for patients with complicated cholecystitis.It is important to control the perioperative hemorrhage and bile leakage.

Objective To evaluate percutaneous endoscopic gastrostomy (PEG) for long-term enteral nutrition in patients with cancers of head and neck. Methods PEGs were performed for 12 patients with head and neck cancers, the indication for which included serious buccal mucositis, difficulty in swallowing, anorexia, and obstruction of the digestive tract. Before PEG and 8 weeks after PEG, serum concentrations of total protein and albumin of the patients were measured, body composition including body weight, free fat mass, and fat mass were measured by bioelectric impedance analysis (BIA), and Karnofsky performance score ( KPS) was evaluated. Results After enteral nutrition for 8 weeks through PEG, the serum concentrations of total protein and albumin of the patients increased significantly (63.8?0.3g/L vs 57.4?0.2g/L, P

Objective To study the assisted diagnostic value and significance in precise surgery of MSCT angiography in torsion of ovar-ian tumors in children. Methods The dual-phase enhanced MSCT images data of 15 children patients with ovarian tumor torsion which were confirmed by surgery were retrospectively analyzed. Showed the vascular changes around the ovaries and judged the ovarian tumors arise and torsion side with the vascular reconstruction methods of multi-planar reconstruction (MPR),maximum intensity projection (MIP),volume rendering ( VR) ,then compared with the operation situation. Results Among the 15 cases aged from 2 months to 11 years old who were de-tected with MSCT scanning and angiography, there were 11 cases of benign tumor (9 cases of ovarian teratoma and 2 cases of serous cystade-noma) and 4 cases of malignant tumor (3 cases of yolk sac tumor and 1 case of malignant mixed germ cell tumor). MSCTA displayed that o-varian vessels changes were abnormal thickening and twisting of distal feeding artery and tumor vascular network formation;and there were thickening, tortuosity, increased density and a few visible‘whirl sign’ in draining veins. Preoperative MSCTA displayed ovarian tumor blood supply arteries were found 5 cases of downlink of ovarian artery and 10 cases of asscending branches of uterine artery. There were 4 cases of ovarian tumor originated from the left ovary combined with reverse and 11 cases originated from the right ovary combined with reverse, which were consistent with intraoperative findings. Intraoperative MSCTA provide information which helped accurate chose of the surgical incision, precise abruption of tumor blood vessels and resection of the tumor and ovarian lesions, thus saved the operation time and reduced the blood loss. Conclusion MSCT angiography can not only provide diagnosis information of torsion of ovarian tumors in children,but also more impor-tantly,it has an important assisted significance in precision surgery.

Objective · To investigate the histone methyltransferase capability of DOT1L-long form and its role in breast cancer metastasis.Methods · The existence of DOT1L-long form was confirmed by PCR, and the mRNA level of DOT1L was tested by real-time PCR. In HEK293T cells in which DOT1L canonical and DOT1L-long were overexpressed respectively, Western blotting was used to test the expression level of DOT1L and the histone methyltransferase capability. In the MCF10A cell line with inducible expression of DOT1L-long, real-time PCR was used to detect the mRNA level of epithelial-mesenchymal transition (EMT) marker, and transwell assay was used to detect the migration of breast cancer cells in which the expression level of DOT1L is low or high. Results · PCR demonstrated the existence of DOT1L-long form, and real-time PCR showed it widely exists in HCT116, T98G, MCF10A cells, etc. Western blotting showed the expression of DOT1L-long form and its H3K79 methyltransferase activity. In MCF10A cells in which overexpressed canonical DOT1L and DOT1L-long, mRNA levels of N-cadherin and fibronectine increased. Transwell showed canonical DOT1L and DOT1L-long both substantially increased the migration of breast cancer cells. Conclusion · The existence of DOT1L-long was confirmed and investigated, which is 202 amino acids longer than the canonical DOT1L, and is coded by a new exon, located between exon 27 and 28. Further, the DOT1L-long has H3K79 methyltransferase activity, and is able to promote breast cancer metastasis.
