This paper reports diagnostic results of 200 cases of hemoptysis. The causes of hemoptysis mainly include: bronchial and pulmonary infections (28%), tracheal,bronchial and pulmonary tumor (22.5%),tuberculosis (9.5%), pulmonary abscess (4%), other pulmonary diseases (2.5%), dosprders pitside the lungs (6.5%), and diseases of unidentified reason (5.5%). The diagnostic procedure of hemoptysis is also discussed. It is especially emphasized that the Pulmonary biopsy via bronchia and technique of systematic segmental lavage are of crucial importance for the diagnosis of hemoptysis.

Objective Based on the liver biopsy samples in the past 10 years, this study aimed to investigate the incidence of fatty liver, the relationship among fatty liver and other underlying liver diseases, the clinical and pathological characteristics and the risk factors of fatty liver. Methods In the total 658 cases of liver biopsy from 1988 to 1997, there were 71 cases of fatty liver, among them 68 cases were nonalcoholic fatty liver. Matched by sex and age, 155 cases of non fatty liver cases were taken as control. All cases had had the tests of liver function, blood lipid profile, blood glucose and hepatitis virus markers. Liver biopsy samples were investigated by pathologists. Results The incidence of fatty liver among all the liver biopsy cases was 10.8%. The patients' ALT, AST, TB and CB levels in fatty liver group were significantly lower than in non fatty liver group ( P

Objective To study the effects of broad-spectrum antibiotics, including the third generation Cephalosporin and Carbapenems, on intestinal enterococci in septic rats. Methods Ninety-one SD rats were randomly divided into normal control group, scald group, scald group with 3 days of ceftriaxone treatment, scald group with 9 days of ceftriaxone treatment, scald group with 3 days of imipenem treatment, scald group with 9 days of imipenem treatment, and sepsis group, sepsis group with 3 days of ceftriaxone treatment, sepsis group with 9 days of ceftriaxone treatment, and sepsis group with 3 days of imipenem treatment, sepsis group with 9 days of imipenem treatment. All the animal were subjected to 30% TBSA Ⅲ degree scald injury on their back, followed by endotoxin challenge with a dose of 20mg/kg 24 hours after the burn injury. The animals were treated with intraperitoneal injection of ceftriaxone (60mg/kg, q12h) or imipenem (60mg/kg, q12h) 24h after the second hit with endotoxin. At the end of the treatment, intestinal enterococci in colon were cultured. The number and variety of the bacteria were also determined. Results The number of enterococci in the gut of the septic rats was significantly increased after the second hit with endotoxin, exceeding that of the rats in normal control group and scald group(P

Objective To study the effects of broad-spectrum antibiotics, including the third generation Cephalosporin and Carbapenems, on intestinal commensal bacilli in rats with sepsis. Methods Ninety-one SD rats were randomly divided into normal control group, scald group, scald group with 3 days of ceftriaxone treatment, scald group with 9 days of ceftriaxone treatment, scald group with 3 days of imipenem treatment, scald group with 9 days of imipenem treatment, and sepsis group, sepsis group with 3 days of ceftriaxone treatment, sepsis group with 9 days of ceftriaxone treatment, and sepsis group with 3 days of imipenem treatment, sepsis group with 9 days of imipenem treatment. All the animal were subjected to 30% Ⅲdegree scald injury on their back, followed by endotoxin challenge with a dose of 20mg/kg 24 hours after the burn injury. The animals were treated with intraperitoneal injection of ceftriaxone (60mg/kg, q12h) or imipenem (60mg/kg, q12h) 24h after the second hit with endotoxin. At the end of the treatment, bacilli in the colon were cultured. The number and variety of the bacteria were also determined. Results The antibiotics obviously reduced the number of colibacilli(P

To evaluate availability of permissive hypercapnia (PHC) in patients with severe acute respiratory distress syndrome (ARDS). Method: To observe the influence of different tidal volumes (V_T) on pulmonary mechanics and hymodynamies in 10 patients with severe ARDS. Result : PHC was induced by decreasing VT from 10-12 ml/kg(routine V_T) to 6-8 ml/kg (small V_T). Arterial oxygen pressure and saturation remained unchanged, but pulmonary venous mixture increased(P

Objective To report long term results of 30 patients with primary intracranial germinoma and evaluate the treatment policy. Methods After the tumor of these 30 patients was completely or partially removed they were routinely given radiation therapy with the conventional extenal irradiation. Of these 30 patients, 28 received prophylactic whole brain irradiation followed by the cone down technique to the local site to an effective dose except 2 patients who were treated locally without prophylactic irradiation.Nineteen patients received prophylactic spinal cord irradiation.Results The overall 5 ,10 , 15 ,19 year survival rates were 93.1%, 87.6% ,87.6% and 68.2%,respectively.The two patients who did not receive prophylactic whole brain irradiation (1 patient) or too low a dose of that (1 patient) developed metastasis in the brain and spinal cord were given a second course of radiotherapy. One survived for 17 years and the other is living now over 10 years. The overall response rate (CR + PR) was 95%.Conclusions While surgery is indicated to reduce the tumor volume, shunt the hydrocrania and obtain a pathologic diagnosis, radiotherapy is invaluable to cure germinoma. Prophylactic whole brain irradiation of 26～30 Gy is necessary and the curative local dose should be 50～55 Gy. Prophylactic spinal cord irradiation is not indicated routinely except some appropriate patients. For patients younger than 14 years, shielding of the pituitary is necessary while the prophylactic whole brain is being irradiated. The tumor dose at the sella turcica region should be limited to 56 Gy, and the spinal cord need not be irradiated prophylactically.

0.05).The clinical outcomes were evaluated according to improvement HSS knee joint function scoring,and the score showed an average of 87.5 points (range,71-97).[Conclusion]The dual-incision technique resulted in accurate fracture reduction with low tissue complication rate,and the medial and lateral plating treatment achieved improved stabilization which enabled mobilization of the knee joint to start immediately after surgery.Medial and lateral plating treatment with dual incisions is a safe and effective technique for Schatzker type Ⅴ tibial plateau fractures.

Objective:To evaluate the physiologic work of breathing (WOBphy)as parameter of respiratory weaning and extubation. Method: Patient work of breathing (WOBt) and imposed work of breathing (WOBimp) were measured. WOBphy was obtained with WOBt minuting WOBimp. In the patients who did not meet conventional respiratory weaning parameters ,if WOBphy

Prone position ventilation has become an important part of lung protective ventilation in acute respiratory distress syndrome (ARDS) patients. Timely and appropriate implementation can improve the mortality of such patients. The same is true for patients with critical coronavirus disease 2019 (COVID-19) patients, but safety assessment, control of implementation details and prevention of complications still need to be further standardized during the practical procedure of prone position ventilation. The purpose of this paper is to explain the specific requirements and key points of prone position ventilation in critical COVID-19 patients, in order to promote the application of prone position ventilation in the treatment of patients with critical COVID-19 and reduce the occurrence of related complications.

PurposeTo establish sensitive and reliable serum marker on liver fibrosis for early clinical diagnosis. MethodsSerum hyaluronate acid,type Ⅲ procollagen and type Ⅳ procogen of 48 patients with viral hepatitis were analyzed by radioimmunoassay and ELISA respectively. ResultsThe serum HA, PCⅢ and PCⅣ level increased gradually with the progress of the disease. Their levels were correlated distinctly with the index of hepatic activity of inflammation and that of fibrosis.ConclusionsThe value of serum HA,PCⅢ and PCⅣ in predicting liver fibrosis will be enhanced ff the effect of inflammation could be excluded.
