Ovjective To observe the surgically excised specimens from eyes with hemorrhagic age-related macular degeneration (AMD). Methods Thirty-six surgically excised specimens were captured from 36 patients with hemorrhagic AMD, 26 specimens were diagnosed as occult choroidal neovascular membrane (CNVM), 10 specimens were diagnosed as polypoidal choroidal vasculopathy (PCV). All specimens were routinely processed by hematoxylin and eosin, periodic acidSchiffprime;s stain and Masson stainings. At the maximum horizontal and vertical slice of the specimens, the category and amount of the cells in the specimen were recorded, as well as the relationship between the specimens and the surrounding tissue. Results The 36 specimens are categorized as neovascular membrane dominant (19/36), collagen fiber dominant (6/36), blood clot dominant (8/36) and degenerated thickened Bruch`s membrane dominant (3/36). Eighteen occult CNVM specimens and 1 PCV specimen are categorized as neovascular membrane dominant; all 6 collagen fiber dominant specimens are occult CNVM; 1 occult CNVM and 7 PCV specimens are categorized as blood clot dominant; and 1 occult CNVM and 2 PCV specimens are categorized as degenerated thickened Bruch`s membrane dominant. The occult CNVM categorized as neovascular membrane dominant present as small blood vessel with single endothelium cell attached; the PCV specimen categorized as neovascular dominant presents as big blood vessel with thick vessel wall under the Bruch`s membrane, retinal pigment epithelium and choroidal melanocyte are both observed in the PCV specimens. Conclusion The components of the specimens captured from eyes with hemorrhagic AMD are diversified.
目的探讨腹膜假性粘液瘤的诊断和治疗。方法对本院1988~2002年收治的5例腹膜假性粘液瘤的临床资料进行回顾性分析，并结合文献加以讨论。结果该5例患者的主要临床表现为腹胀、腹痛、腹部包块，其中4例行减瘤手术治疗，并在术后辅以腹腔内化疗。术后随访，1例3年内死亡，1例7年内死亡，另2例现已分别存活9年零5个月和3个月。结论腹膜假性粘液瘤是一种少见疾病，其来源多见于阑尾，术前诊断困难，多次针吸和血清癌胚抗原检查对诊断可能有帮助。多数患者术中探查可见腹腔内广泛病变，一次清除很困难，往往需采取多次减瘤术。外科手术治疗仍是目前有效的治疗手段。
Pancreatic sinistral portal hypertension (PSPH) is a clinical syndrome resulting from pancreatic disease that blocks splenic vein return, which includes acute and chronic pancreatitis, pancreatic tumors, and iatrogenic factors related to pancreatic surgery. Most PSPH patients present with isolated gastric varices, splenomegaly and hypersplenism, with normal liver function, and upper gastrointestinal bleeding caused by varices in the fundus of the stomach is the most serious clinical manifestation. The treatment of PSPH can be divided into the treatment of portal hypertension in the spleen and stomach region, including close follow-up, medication, endoscopic therapy, splenic artery embolization and splenectomy, etc. The primary diseases of pancreas are mainly treated for acute pancreatitis, chronic pancreatitis and pancreatic tumor. In particular, PSPH related to pancreatic surgery should be concerned.
ObjectiveTo explore the effectiveness of minimally invasive clamp reduction technique via anterior approach in treatment of irreducible intertrochanteric femoral fractures.MethodsBetween January 2015 and January 2019, 59 patients with irreducible intertrochanteric femoral fractures were treated with minimally invasive clamp reduction technique via anterior approach. There were 29 males and 30 females with an average age of 77.9 years (range, 45-100 years). The causes of injury included falling in 46 cases, traffic accident in 6 cases, smashing in 2 cases, and falling from height in 5 cases. The time from injury to operation was 1-14 days (mean, 3.8 days). The fractures were classified as AO type 31-A1 in 12 cases, type 31-A2 in 25 cases, type 31-A3 in 22 cases.ResultsAll fractures were reduced well and the fracture reduction took 10 to 30 minutes, with an average of 19 minutes. All patients were followed up 13-25 months, with an average of 17.6 months. Among them, 2 cases of pronation displacement of proximal fracture segment died for infection or falling pneumonia after internal fixation failed. Six patients with reversed intertrochanteric femoral fractures experienced re-pronation and abduction displacement of the lateral wall after internal fixation, but the fractures all healed. The rest of the patients had no fracture reduction loss, and the fractures healed with an average healing time of 5.9 months (range, 3-9 months). Except for 2 patients who died, the Harris score of hip joint function of the remaining 57 patients was excellent in 49 cases and good in 8 cases at last follow-up.ConclusionThe minimally invasive clamp reduction technique via anterior approach for irreducible intertrochanteric femoral fractures is simple and effective. For irreducible intertrochanteric femoral fractures related to lateral wall displacement, after clamp reduction and intramedullary nail fixation, the lateral wall should be reinforced in order to avoid reduction loss and internal fixation failure.
Objective To survey the current status of residents’ health examination in township medical units in Shuangliu county, so as to provide references for exploring the residents’ health examination mode suitable for the well-off rural hospitals, and for improving the effects of physical examination. Methods The self-designed questionnaires were made to survey the current situation of health examination for the residents in 24 township medical units in Shuangliu County, including 3 central township hospitals, 3 community health centers and 18 general township hospitals; and the outline was designed to interview the people responsible for managing and implementing the resident’s examination work. The Epidate 3.1 was used for data input, the SPSS 17.0 was used for descriptive statistics and stratified analysis, and the classification method was adopted for qualitative research of personal interview data. Results The number of primary health care units for carrying out residents’ health examination got gradually increased year by year from 2008 to 2010; and all 24 township-level medical units had already carried out that examination by 2010. But some issues still existed such as lower participation rate and ineffective utilization of the archives. Conclusion a) It is necessary to prepare well, enhance organizing, expand publicity, and increase participation rate when primary health care units carry out the health examination for residents; b) It is necessary requires to fasten the informatization construction of health archives, and to quicken the process and analysis of examination information; and c) It is advisable to constantly optimize the examination items according to exam information, to improve the qualification of medical staffs, and to fasten the construction of exam team.
Objective To survey the drug distribution status in 24 township medical units in Shuangliu county, so as to provide references to explore the drug distribution mode for well-off township hospital. Methods An outline was made to interview the relevant workers who were in charge of the rural drug distribution management in all levels of the food and drug supervision bureaus of Sichuan province, Chengdu city or Shuangliu county, the township hospitals, the village clinics, and the drug distribution enterprises. At the same time, a self-designed questionnaire was distributed to 24 county township medical units (ie, three central township hospitals, three community health centers, and 18 general township hospitals). The Epidate3.1 was used for data-inputting, and the SPSS 17.0 was used for descriptive statistics and stratified analyses. Results At present, there was only one enterprise taking responsibility of the rural drug distribution in Shuangliu county since the strategy of enterprise direct-distribution under “two nets” supervision starting iShuangliu county of Sichuan province; Township medical units; Drug distribution; Status surveyn 2003, and there was no obvious difference in distribution before and after that strategy. The general satisfaction of 24 county township medical units with the distribution enterprise was only 50%, and the satisfaction with the price and the number of drug distribution was the lowest, accounting for 37.5% and 33.3%, respectively. Conclusion The enterprise direct-distribution under the “two nets” supervision for rural drug distribution makes the drug distribution market regular and gets good social effect, but there are still the same problems such as lack of marketization, low transparency, and high drug price, so it is necessary to introduce a new competition and management mechanism to promote the new breakthrough in rural drug distribution.
