OBJECTIVETo study clinical effects of one-hole microplate internal fixation for the treatment of collateral ligament injuries of the metacarpophalangeal joint of the thumb combined with fracture.

METHODSTwenty-two patients (16 males, 6 females) with collateral ligament injuries of the metacarpophalangeal joint of the thumb combined fracture were treated with one-hole microplate internal fixation. The age of the patients ranged from 18 to 53 years old with a mean age of 28.5 years old. The duration from injury to surgery ranged from 2 hours to 2 months, and the mean time was 6 days. All the patients had collateral ligament injuries combined with fracture of the metacarpophalangeal joint of the thumb. Thirteen patients had injuries in the right hand and 9 patients had injuries in the left hand. There were 18 cases of closed wound and 4 cases of open wound. Eighteen patients had fresh injuries (< 2 weeks) and 4 had old injuries (> 2 weeks). Sixteen patients had injuries in the ulnar collateral ligament of the thumb combined with fracture, 6 patients had radial collateral ligament injuries of the thumb combined with fracture, 4 cases of which were complicated with injuries of abductor pollicis brevis and the end of the flexor pollicis brevis tender. The size of the avulsed fragment was about 3.0 mm x 4.0 mm to 6.0 mm x 7.0 mm.

RESULTSThe incisions of 22 patients healed by first intention. The follow-up periods ranged from 6 months to 5 years old,with an average of 2.5 years old. The thumb function was evaluated by Saetta and other evaluation criteria, and 20 patients got an excellent result and 2 good.

CONCLUSIONThe application of one-hole microplate internal fixation in treating collateral ligament injuries with fracture of the metacarpophalangeal joint of the thumb is an effective method.

Objective To study the clinical features and to improve the treatment on the elderly patients with brain tumor.Methods Retrospective analysis of 163 cases with brain tumor which had been confirmed by CT,MRA or pathology.Results Of all the 163 cases,121 were located in supratentorium,most of which were meningiomas and gliomas.Most patients(129 cases)had comorbidity.After operation,symptoms disappeared or obviously improved in 126 cases,moderately improved in 19 cases,and did not changed in 6 patients.Twelve cases died after operation in a month, in which 9 patients were over 75 years old.The death rate of operation was 6.1%.Conclusions It is important to know the atypical manifestation of brain tumor in the elderly,which may prevent clinical misdiagnosis and mistherapy.The perioperative management is indispensable to the prognosis of the patients.The choice of operation and medication should be in individualized.

The treatment of bleeding wound of solid visceral and the rescue of uncontrollable bleeding are still confronted with difficulties in surgery and first-aid field. Many researchers devote to study in the field of hemostasis, and the novel porous hemostatic agent is one of the hot spot of research about hemostasis. The review focuses on the hemostatic effect, properties, hemostatic mechanism, shortcoming and future trends of three novel porous hemostatic agents such as polysaccharides, zeolite and wollastonite.

Objective To investigate the expression of the interleukin-1 receptor(IL-1R)Ⅰ,IL-1RⅡand IL-1R accessory protein(IL-1RAcP)in osteoarthritis and analyse their biological significance.Methods Immunohistochemistry and reverse transcription-polymerase chain raction(RT-PCR)were adopted to detect the expression of IL-1RⅠ,IL-1RⅡand IL-1RAcP on the synovium of 107 OA patients.Results Immunohis- tochemistry showed strong positive expression of IL-1RⅠand IL-1RAcP,and positive expression of IL-1RⅡ. The expression was distributed in lining cells,monocyts and vascular endothelial cells of the sublining area, but all of them were negative or weak positive in normal synoviums.RT-PCR showed the expression of IL-1RⅠ,IL-1RⅡand IL-1RAcP in OA synoviums was significantly enhanced than normal synoviums (P＜0.05),and the expression of IL-1RⅠwas significantly enhanced than IL-1RⅡ(P＜0.05),but no sig- nificant difference with IL-1RAcP(P＞0.05).In stageⅡandⅢOA synoviums,the expression of IL-1RⅠand IL-1 RAcP had no significant difference with normal synoviums(P＞0.05).The expression of IL-1RⅡin stageⅢOA synoviums was significantly enhanced than normal(P＜0.05).Conclusion IL-1RⅠ,IL-1RⅡand IL-1RAcP play significant roles in the pathogenesis of OA,especially IL-1RⅠand IL-1RAcP.But their increase is only observed in the early stage of OA.These suggest that they may have no association with the development of OA and have no direct association with the severity of OA.OA can be cured by interrupting the signal transduction path in which IL-1 has played biological roles.

BACKGROUNDIf the emphysema lesions are not symmetrical, unilateral lung volume reduction surgery (LVRS) can be carried out on the more severe side. The aim of this research was to evaluate the feasibility and effects of LVRS performed simultaneously with resection of pulmonary and esophageal neoplasms.

METHODSForty-five patients with pulmonary neoplasm and 37 patients with esophageal neoplasm were randomly assigned to group A or group B. In group A, LVRS was performed simultaneously on the same side as thoracotomy. In group B, only tumor resection was performed. The nonfunctional lung area was determined by preoperative chest computed tomography and lung ventilation/perfusion scan. The lung volume removed was about 20% to 30% of the lobes on one side. Preoperative and postoperative indexes including pulmonary function testing variables, arterial blood gas analysis variables, dyspnea scale, 6-minute walk distance, etc., were compared between the groups.

RESULTSThere were no surgical deaths in this study. The postoperative forced vital capacity in 1 second, PaO2, PaCO2, dyspnea scale, and 6-minute walk distance were improved significantly in group A, whereas these indexes did not change or decreased slightly in group B.

CONCLUSIONSFor tumor patients who have associated emphysema, simultaneous LVRS not only increases the chance of receiving surgical therapy, but also improves the postoperative quality of life of the patient. LVRS has expanded the surgical indication for tumor patients.

In the present study, an ultra performance liquid chromatography coupled with time-of-flight mass spectrometry (UPLC/Q-TOFMS) based on chemical profiling approach to evaluate chemical constitution between mixed decoction and co-decoction of monkshood-pinellia combination of the eighteen incompatible medications (Shi Ba Fan) was proposed. Two different kinds of decoctions, namely monkshood-pinellia co-decoction: water extract of the two herbs together, and monkshood-pinellia mixed decoction: water extract of each individual herbs mixed together, were prepared. Batches of these two kinds of decoction samples were subjected to UPLC/Q-TOFMS analysis, the datasets were processed with MassLynx 4.1 to holistically compare the difference between these two kinds of decoction samples. The most changed components during decocting were analyzed. Using the proposed approach, global chemical difference was found between co-decoction and mixed decoction, mesaconitine, aconitine and hypaconitine were identified as the most changed components (changed most significantly) during decocting. Result shows significant difference between two kinds of decoction samples, and the significant differences are probably related to the incompatibility of monkshood and pinellia.
