ObjectiveTo study the application of retinal tomography in primary open angle glaucoma diagnosis.MethodsThe differences between POAG, high myopia with suspected glaucoma and normal volunteers on the rim area, rim volume and the thickness of retinal nerve fiber layer (RNFL) thickness in quadrants under Heideberg retinal tomography-Ⅱ(HRT-Ⅱ) were analyzed.ResultsIn the cases of POAG and high myopia with suspected glaucoma, the values of rim area, rim volume and RNFL thickness were significantly lower than that in normal group.ConclusionRetinal tomography can be used in the diagnosis of POAG.

Objective To establish a rabbit auricular hematoma model,to observe the process of production and absorption,and to study the location of hematoma and method of its removal Methods Ten health New Zealand rabbits were divided randomly into control group and experimental group.A weight was dropped onto particular locality of auricles 3-6 times until a big hematoma appeared.The pathological processes of hematoma were observed,and the hematoma was formed 1 hour and the hematoma was almost absorbed after 4 days.The drainage experiment was conducted to observe the effect of needle aspiration or incision and drainage on the hematoma.Results All experimen tal auricles formed hematoma.The histopathological study showed that hematoma located between skin and cartilage,did not involve the cartilage.After 4 days,new-formed capillaries and fibroblasts were found,and then hematoma mostly absorbed; fibrous hyperplasia was been found.By cutting the hematoma,the blood clot could be thoroughly removed.Conclusions The auricular hematoma model can be established easily by striking with a heavy weight.Hematoma locates in subcutaneous connective tissue.A large hematoma should be early removed for prevention of auricular deformity.

[Summary] In newly diagnosed diabetic patients, fasting plasma glucose, HbA1C , and plasma lipid profiles were measured to analyze the association between HbA1C and plasma lipid profiles. HbA1C might affect plasma lipid profiles in newly diagnosed diabetic patients. Higher HbA1C was associated with the worse plasma lipid profiles and more severe insulin resistance.

This article was aimed to study the optimum technological conditions of roller compaction of FKⅣ gran-ules. This experimentation compared content of two granule preparation techniques which were the dry process gran-ulation and the wet process granulation, and adopted L9(34) orthogonal experiment to study the technological parame-ters of FKⅣ granules. The dry process granulation was selected. And factors such as roller pressure, roller speedand moisture content of power, which influence the result of granule yield were also studied in the dry process gran-ulation. The results showed that the optimum technological conditions were roller pressure at 5.0 Mpa, roller speed at 400 rpm, and moisture content of power at 3.0%. It was concluded that the roller compaction process of FKⅣ gran-ules was feasible in production which was able to meet the requirement of production.

Objective To investigate the role of insulin resistance in patients with prostate cancer who received surgical castration. Methods Sixty-seven patients with advanced prostate cancer who received with surgical castration were divided into obesity group [30 cases, BMI (26.85±1.22) kg/m2] and non-obesity group[37 cases, BMI(22.72±1.28) kg/m2]. The fasting blood glucose (FBG) and the fasting serum insulin, while evaluated the insulin resistance index(IRI) were determined before treatment, 6 months after treatment and 12 months after treatment. Results The levels of fasting serum insulin were significantly higher 6 months[(23.21±5.78 )mU/L] and 12 months [(24.34±5.37) mU/L] after treatment than that be-fore treatment[(20.01±4.82) mU/L] in obesity group, but 12 months after treatment [(22.19±6.14) mU/L ]was higher than that before treatment [(17.36±6.01) mU/L] in non-obesity group (P<0.01). The IRI were significantly higher 6 months (2.94±0.79) and 12 months (3.10±0.73) after treatment than that be-fore treatment (2.53±0.64) in obesity group, but 12 months after treatment (2.79±0.75) was higher than that before treatmeat(2.17±0.73) in non-obesity group(P<0.01). Conclusion The current data suggests that the patients with prostate cancer who received surgical castration is at risk for developing insulin resistance, thus leading to increasing risk of cardiovascular disease and type 2 diabetes mellitus.

Objective To observe the effects of combined generalepidural anesthesia on perioperative myocardial enzymogram and troponin T of the myocardium(cTnT)in old patients undergoing thoracic surgery.Methods Thirty-eight ASAⅠ-Ⅱ patients aged 60～80 years old were randomly divided into two groups.General anesthesia group(group G): anesthesia was induced with fentanly,propofol and vecuronium and maintained with isoflurane,propofol and vecuronium.Combined anesthesia group(group C):general anesthesia was performed as in group G and continuous epidural block with(1.6%) lidocaine was added during operation.Peripheral blood CK,CK-MB,AST,LDH and cTnT were measured before anesthesia,at the end of operation and at 6,24,48 hours after operation.Results Two groups could provide same postoperative analgesia.There was no change for HR,RR and MAP in two groups.Serum CK,AST,LDH and cTnT concentration in group G after operation were significantly higher than those before anesthesia(P

Objective The biological effects of BMP3 on osteosarcoma were investigated by treating human osteosarcoma cell lines MG63,and U2OS with human BMP3(hBMP3).Methods Osteosarcoma cells in experimental groups were respectively treated with AdBMP-3 and rhBMP3-CM,control groups with AdGFP and rGFP-CM,the blank group with neither.Their ability of proliferation,apoptosis,transmigration and differentiation were respectively detected by trypan blue exclusion test,terminal deoynucleotidyl transferase mediated dUTP nick end labeling(TUNEL) and acridine orange-ethidium bromide fluorescent stain(AO/EB),transwell-room and alkaline phosphatase(ALP) activity reagent kit.Results(1) All the indexes detected were not significantly different between two control groups.(2) Compared with control groups,the cell survival rate showed a significant decrease in experimental groups.(3) The apoptosis indexes increased.(4)The number of trans-membrane cell decreased.(5)The activity of alkaline phosphatase increased after treatment with AdBMP3 and rhBMP-3 for 3 days in MG63,5 days in U2OS.Conclusion hBMP3 inhibit osteosarcoma cells growth and promote bone formation.

OBJECTIVETo investigate the effect of polyethylene oxide (PEO) on renal blood flow and its renoprotective effect in rabbits with endotoxin sepsis.

METHODSTwenty normal New Zealand white rabbits were randomly divided into normal saline (NS) group and PEO group (n=10), and endotoxin shock was induced by an intravenous injection of 0.6 mg/kg lipopolysaccharide. Resuscitation was performed when the blood pressure of the rabbits showed a 30% decline, using NS (in NS group) or the mixture of equal volumes of NS and 20 ng/g PEO (in PEO group) perfused at the rate of 5 ml/kg per hour. Before and during shock and at 1 h after resuscitation, the renal hemodynamics was monitored by ultrasound and the venous blood was extracted to examine the renal functions. The heart rate and arterial blood pressure were monitored throughout the experiment.

RESULTSThe rabbits in both groups showed a significantly lower renal artery blood flow velocity during the shock (P<0.05) with significantly increased pulsatility index (PI) and resistance index (RI) compared with those before the shock. One hour after resuscitation, the blood flow velocity in the renal arteries at all levels and the tertiary veins were reduced in NS group without obvious reduction of the PI and RI; in PEO group, the blood flow velocities in the renal arteries increased significantly compared to those before shock (P<0.05), and the PI and RI of the tertiary arteries were significantly lower than those in NS group (P<0.05). In both groups, BUN and Cr increased during endotoxin shock stage, and 1 h after resuscitation, PEO group showed significantly lower BUN and Cr levels than NS group (P<0.05).

CONCLUSIONA small dose of PEO can significantly promote renal perfusion in rabbits with septic shock, thus offering renoprotective effect against early damage in septicopyemia and septic shock.

Objective:To investigate the early clinical characteristics and radiographic changes in confirmed novel coronavirus pneumonia (COVID-19) and COVID-19 excluded patients.Methods:Twenty-four patients with suspected COVID-19 admitted to Shanghai Jiaotong University Affiliated Sixth People’s Hospital and Jinshan Branch Hospital between January and February, 2020 were enrolled in this research. Early clinical features and radiographic changes were analyzed in 10 confirmed COVID-19 patients and 14 COVID-19 excluded patients.Results:In the early stage, all 24 suspected patients had minor symptoms, and had normal blood gas analysis results. Of 10 confirmed COVID-19 patients, 5 patients were male. All the 10 patients had fever and fatigue, with body temperature between 37.5 and 38.5 °C. Only 1 patient had hacking cough. Two patients had no clear epidemiological exposure history, the other 8 had clear epidemiological exposure history, with a possible incubation period of 1-10 days. From CT imaging, lesions were characterized as ground glass shadow ( n=9), which could be unilateral ( n=1) or bilateral ( n=9), and were mainly close to the pleura ( n=9), with nodule shadow ( n=1) and without focal necrosis, and could combined with pleural effusion ( n=1). Among the COVID-19 excluded patients, all 14 patients had clear history of epidemic exposure, with an onset time of 1 to 13 days. Twelve patients had fever, including 4 patients with body temperature > 38.5 °C, 8 patients with body temperature bwteen 37.3-38.5 °C, and 2 patients without fever. All patients had fatigue, 7 patients had hacking cough and 2 patients had chest pain. From CT imaging, ground glass shadow appeared in 4 patients, lesions were unilateral in 10 patients and bilateral in 4 patients, and the lesions were relatively sporadic, without necrosis or pleural effusion. Conclusions:Not all patients with COVID-19 have a direct epidemiology exposure history, some patients may be infected unknowingly. According to CT imaging, COVID-19 seems to have no special manifestations being different from other viral pneumonia. COVID-19 is more common among middle-aged people.
