BACKGROUND:Manual reduction for external fixation of distal radius fractures can achieve good outcomes.
OBJECTIVE:To carry out the bibliometric analysis on manual reduction for external fixation of distal radius fractures.
METHODS:Literatures concerning reduction for external fixation of distal radius fractures were retrieved in CNKI database from 2003 to 2012. The keywords were“external fixation;distal radius fractures”. Duplicate and irrelevant articles were eliminated, and a total of 408 articles were retrieved. A bibliometric analysis of these 408 articles was performed in terms of publishing time and number, subject categories, source journals, research institutions, times cited and download frequency.
RESULTS AND CONCLUSION:Literatures concerning manual reduction for external fixation of distal radius fractures exhibit an upward trend in number. In 2012, there were 85 relevant articles. In the past 10 years, 18 relevant articles have been published in Chinese Journal of Traditional Medical Traumatology&Orthopedics, which is the most. There are not many relevant studies in various research units, only 1-7 articles published per unit, and five articles are funded.

Objective To investigate the influence of high intensity focused ultrasound(HIFU) ablation therapy on pregnancy outcomes in the patients with adenomyosis(AM).Methods Twenty patients with AM and successful pregnancy after HIFU ablation in Chongqing Haifu Hospital from April 2011 to February 2016 were selected.Their pregnancy and delivery situation were retrospectively analyzed.Results After HIFU treatment,the symptoms of dymenorrhea and menorrhagia were significantly improved compared with before operation(P＜0.05).The average fertilization time after HIFU was(8.75 ± 6.23) months,among them 11 cases succeeded in delivery,5 cases had spontaneous abortion,1 case was ectopic pregnancy,1 case took artificial abortion and 2 cases were still in pregnant period all cases had no uterime rupture during pregnant or delivery period.Neonateswere healthy.Conclusion HIFU ablation is an effective mode for treating AM and can be used in the patients with AM and birth demand.

s:Objective To explore the anatomical distribution characteristics of pelvic endometriosis lesion, size of the cyst, tissue ad-hesion degree and the correlation with the pain symptoms in patients with ovarian endometriosis cyst. Methods 342 cases of patients with o-varian endometriosis cyst who has underwent gynecologic laparoscopic surgical treatment in our hospital were selected as the research objects. According to the pain symptoms, they were divided into the pain group (195 cases) and the painless group (147 cases). The influence of cyst growth area and size on the pain symptoms were compared, and whether there were cyst adhesion and the relationship between adhesion area and pain were analyzed. Results The operation time of pain group was longer. The average operation time was 81. 2 min in pain group while it was 62. 1 min in painless group. The bleeding volum was 74. 3 mL in pain group which was higher than 56. 2 mL in the painless group. The average diameter of cyst was 11. 26 cm in the Pain group, and it was 6. 10 cm painless group. Rate of adhesions in patients of pain group was significantly higher than that of the painless group. Adhesion occured most frequently in ovary, followed by the fallopian tubes. Conclusion Pain symptoms have a close relation with cyst diameter and degree of surrounding tissue adhesion. As the cyst diameter get larger and the surrounding tissue adhesions grow broader, the pain symptoms would be more significant in patients .

Objective To investigate the causes,diagnosis and treatment of small intestine bleeding.Methods Sixty-eight cases of small intestine bleeding from January 2000 to June 2010 were retrospectively analyzed.Among all cases,4 underwent routine hemostatic treatment under colonoscopy,40treated with open surgery and 24 patients with laparoscopic therapy.Among them,57 cases underwent part resection for some small intestine,completely laparoscopic resection of diverticula was performed in 7patients.Results Neoplasms was the leading cause of small intestine bleeding,accounting for 48.5％ (33/68)in these patients,followed by small intestine diverticulum accounted for 29.4％ ( 20/68 ),intestinal infective diseases accounted for 14.7％ ( 10/68 ) and vascular disease accounted for 7.4％ ( 5/68 ).Conclusion The clinical manifestations of small intestinal bleeding showed no specific signs.Neoplasm,intestine diverticulum and intestinal infective diseases are the most common causes of small intestinal bleeding.Small intestinal bleeding can be diagnosed in intraoperative colonoscopy.Surgery is the most effective treatment for small intestinal bleeding.

Objective To analyze the clinical and imaging features of pulmonary metastasis of giant cell tumor of bone for clinical diagnosis and treatment.Methods Five patients with histologically proven pulmonary metastasis from giant cell tumor of bone were reviewed,the imaging features and the progression of the pulmonary metastasis were evaluated.Results The first operation of primary tumor was curettages and then local recurrence was seen in all 5 cases.The interval to metastasis ranged from 5 to 26 months.Pulmonary metastasis was diagnosed by chest radiographs in 4 cases and CT in all 5 cases.The imaging findings included solitary solid nodule (n =1),multiple solid nodules and mass (n =5),multiple groundglass nodules (n =1) and complex form (n =2).The dynamic follow-up CT findings showed spontaneous regress nodules (n =1),metastasis occurring again 19 months after surgery of solitary nodule (n =1),some solid nodules unchangable for a long time in 3 patients with multiple nodules.Conclusions The dynamic follow-up CT findings of pulmonary metastasis of giant cell tumor of bone are specific.The regular follow-up could play an essential role in early detection and prognosis of pulmonary metastasis within 2 years after primary tumor diagnosed.

Objectives To summarize the clinical characteristics of imported falciparum malaria patients and the treatment so as to provide the evidences for improving the diagnosis and treatment of the disease. Methods A total of 138 imported falci?parum malaria patients who received the treatment in Shandong Institute of Parasitic Diseases from January 2007 to February 2013 were adopted as the observation subjects and their clinical data were collected and analyzed. Results All the 138 pa?tients were back from African countries. The main manifestations were fever headache asthenia and hepatosplenomegaly and most of them were with decreased RBC PLT levels and increased LDH levels and 36.96%of them were misdiagnosed as respiratory diseases nephritis hepatitis and so on. Through antimalarial treatment of artemether or artesunate or dihydroartemis?inin and primaquine or dihydroartemisinin and piperaquine and symptomatic treatment the short?term and long?term cure rates were 98.55%and 94.93%respectively with 1 case unrecovered and 1 died. Conclusions Artemisinins are still the most effective antimalarial drugs for falciparum malaria. However some patients recrudesce as the Plasmodium in their body is resis?tant or insensitive to these drugs. We should pay more attention to the antimalarial and symptomatic treatments in the early stage of severe malaria so as to improve the cure rate.

Objective To assess the safety and the curative effect of the combination of minipercutaneous nephrolithotomy (mini-PCNL) and ureteroscopic lithotripsy (URL) in the treatment of nonhydronephrotic staghorn calculi. Methods The clinical data of 53 eases with non-hydronephrotic staghom calculi treated by mini-PCNL combined with URL were retrospectively analyzed. Results Fifty-three cases (64 renal units) were performed first-stsge operation, 9 renal units were stone free in first-stage operation, 33 renal units were stone free in second-stage operation, other 13 renal units were stone free in third-stage operation. A complete stone clearance rate of 85.9%(55/64) was achieved, and after one to three sessions of mini-PCNL and extracorpereal shock wave lithotripsy afterwards that increased to 95.3% (61/64). Blood transfusion was performed in 3 cases, no major complication was noted in the patients. Conclusions The combination of mini-PCNL and URL has more advantages, less invasions, easier recovery and less complications. It provides a new minimally invasive way for non-hydronephrotic staghorn calculi.

Objective: To explore the status of lymph node metastasis of middle third thoracic esophageal squamous cell carcinoma and its influence on the prognosis and to seek the reasonable range of lymphade-nectomy. Methods: A total of 129 patients who underwent curative esophagectomy with modern two-field lymphadenectomy of middle third thoracic esophageal squamous cell carcinoma were reviewed. Results: The lymph node metastasis rate was 56.6% and the upper mediastinal lymph node metastasis rate was 43.4%. The lymph node metastasis ratio (positive nodes/total dissected nodes, LMR) was 11.3%. Paraesophageal lymph nodes, lymph nodes near the right recurrent nerve, the left gastric and infracadnal lymph nodes were most commonly involved when the tumor was located in the middle thoracic esophagus. Tumor differentiation, the depth of tumor invasion and the length of tumor were influencing factors for lymph node metastasis. The 5-year survival of N_0, N_1 (LMR≤20%) and N_1 (LMR>20%) patients were 50.4%, 31.0% and 6.8%, respective-ly, with a significant difference among the three groups (P=0.000). Conclusion: LMR was one of the key fac-tors affecting the prognosis, of esophageal cancer. Patients with middle third thoracic esophageal carcinoma should be treated with radical surgery with modern two-field lymphadenectomy.

Objective:To investigate the role of endoplasmic reticulum stress (ERS) in the autophagy of RAW264.7 cells induced by SiO 2 and its effect on the secretion of tumor necrosis factor-α. Methods:RAW264.7 cells stimulated by 200 μg/ml SiO 2 were used as an vitro cell model, and different treatment times of SiO 2 were used as variables. They were divided into 0 h treatment group (blank control group) , 6 h, 12 h, 24 h, and 48 h treatment group. The formation of autophagospores was detected by acridine orange and mondane-sulfonate (MDC) staining. Application of real-time quantitative PCR (Real-time PCR) to detect autophagy related molecular Beclin1 mRNA expression and protein immunoblot (Western Blotting) detecting autophagy related proteins LC3Ⅰ, LC3Ⅱ and expression of Beclin1. Real-time PCR and Western blotting were used to detect the expression of ERS specific marker BiP. Secretion of RAW 264.7 cell transforming growth factor-β1 (TGF-β1) and tumor necrosis factor-α (TNF-α) was detected by enzyme-linked immunosorbent assay (ELISA) . ERS inhibitors 4-PBA intervention experiment, including blank control group, SiO 2, 1 μmol/L 4-PBA+SiO 2, 10 μmol/L 4-PBA+SiO 2, 20 μmol/L 4-PBA+SiO 2 treatment group, Western blotting testing LC3Ⅰ, LC3Ⅱ and expression of Beclin1 changes. Results:Compared with the control group, SiO 2-induced fluorescence intensity in RAW264.7 cells was significantly increased, with statistically significant differences ( P<0.05) . Compared with control group, with SiO 2 processing time prolonged, LC3Ⅰ, LC3Ⅱ Beclin1 mRNA and protein expression and protein expression increased, 6 h, 24 h, the height of the differences were statistically significant ( P<0.05) ; Compared with the control group, the mRNA and protein expression level of BiP reached the peak for 6 h, and the expression level in 6 h, 12 h and 24 h groups increased significantly, and the difference was statistically significant ( P<0.05) . Compared with the SiO 2 stimulation group, the LC3Ⅱand Beclin 1 protein levels of RAW264.7 cells were gradually down-regulated by increasing the dose of 4-PBA. With the increase of 4-PBA concentration, the down-regulated levels were more significant, and the difference was statistically significant ( P<0.05) . Compared with the SiO 2 stimulation group, the TNF-α secretion level of RAW264.7 cells significantly decreased of 1, 10, 20 μmol/L 4-PBA+SiO 2 treatment group, and the difference was statistically significant ( P<0.05) .
