Objective To investigate and analyze whether the different types of radial head fracture and internal fixations have influence on the out comeof elbow function after surgery. Methods We reviewed the clinical data of 46 cases of radial head fractures from August 2002 to December 2008, 34 males, and 12 females, aged from 19 to 51years. All these cases underwent open reduction and internal fixation including fixation with Kirschner wire fixation, mini-plate and/or screw fixation and radial head resection. Results Forty-six cases were followed up in this study for a period of 8 months to 4 years (mean 2 yeats and 4 months).According to Mayo assessment of elbow function, the results of 35 cases were excellent or good (35/46 cases, 76.1%). Better function recovery was got in those who were preferred mini-screw internal fixation or combined with mini-plate. The same results were also found in those with Mason type Ⅱ fracture and in those underwent surgery within 2 weeks. Conclusions Good results can be got through surgical treatment as the indication of open reduction is clear, especially in cases with radial head fracture of Mason type Ⅱ and Ⅲ.The type of radial head fracture, the method of internal fixation and the timing of surgery all affect the outcome.

BACKGROUNDTo evaluate the diagnostic value of flow cytometric DNA analysis of sputum cells in lung cancer patients.

METHODSThe DNA content of sputum cells was determined by flow cytometry in 44 patients (29 patients with lung cancer, and 15 patients with benign pulmonary disease). The results of DNA content of sputum cells were compared with those of cytologic morphology of sputum cells.

RESULTSThe last pathologic diagnosis was used as a diagnostic criterion, the sensitivity of DNA heteroploidy analysis was 82.8% , which was significantly higher than that of sputum cytology (82.8% vs 27.6%, P < 0.005); and the positive rate of heteroploidy in sputum samples in stage III and IV disease was significantly higher than that in stage I and II disease (87.5% to 76.9%, P < 0.002 5). In one case, the heteroploidy was found 10 months in advance of cytometry. In the control, heteroploidy was detected in 33.3% (2/6) patients with inflammatory pseudotumor and 50.0% (2/4) patients with tuberculous nodule, who were found with positive staining of Ki67 and PCNA.

CONCLUSIONSFlow cytometry seems to be a valuable adjunctive method for the diagnosis of lung cancer, and probably for the early diagnosis.There are clonal changes in some inflammatory pseudotumor and tuberculous nodule.

To analyze the structural specificity of Shenque (CV 8) in terms of vascular biology from the three aspects of structure, tissue and molecular anatomies. On structural anatomy Shenque (CV 8) possessed defined vascular structure and was the only acupoint directly affected vascular intima. The basis of the specific therapeutic effects was owing to its relation with vessel and abundant microcirculation. Endothelial cells and microvascular endothelial cells were the tissue basis of the starting of therapeutic specificity. Molecular anatomy involved in the functions of transient receptor potential vanilloid family (TRPV) pathway and neuronal peptide secretion of endothelial cells in the structural function of the point. The "restoringfor collapse" effect of salt-partition moxibustion at Shenque (CV 8) was analyzed based on the local biological specificity of blood vessels. The mechanisms were concluded as effectively targeting the dysfunction of microvascular endothelial cells and acquiring the maximum quantity of moxibustion by repeated warm-heat stimulation. The vascular biological structural features of Shenque (CV 8) may contribute to direct therapeutic effects on endothelial cells by the point.

Meigs' syndrome (MS), a rare complication of benign ovarian tumors, is easily misdiagnosed as ovarian cancer (OC). We retrospectively reviewed the clinical laboratory data of patients diagnosed with MS from 2009 to 2018. Serum carbohydrate antigen 125 and HE4 levels were higher in the MS group than in the ovarian thecoma-fibroma (OTF) and healthy control groups (all P < 0.05). However, the serum HE4 levels were lower in the MS group than in the OC group (P < 0.001). A routine blood test showed that the absolute counts and percentages of lymphocytes were significantly lower in the MS group than in the OTF and control groups (all P < 0.05). However, these variables were higher in the MS group than in the OC group (both P < 0.05). The neutrophil-to-lymphocyte ratio (NLR) was also significantly lower, whereas the lymphocyte-to-monocyte ratio was higher in the MS group than in the OC group (both P < 0.05). The NLR, platelet-to-lymphocyte ratio, and systemic immune index were significantly higher in the MS group than in the OTF and control groups (all P < 0.05). The hypoxia-inducible factor-1 mRNA levels were also significantly higher, whereas the glucose transporter 1, lactate dehydrogenase, and enolase 1 mRNA levels were lower in peripheral CD4
