Objective: TO verify through animal experiment the validity of chemical cholecystectomy . Methods: The experimental objects seven healthy juvenile pigs,hardener was infused into the gallbladder,after infusion the samples were collected by pathoiogical examination , according to the different duration under anesthestize. Reslts:The mucous destructive and digestive process remained with one week, the inflammatory reacton in two weeks,the chronic inflatoy reaction compained a a great deal of granu lation tissue and scar formation occurred in 4th-8th week,10 weeks latter,the inflmmatory reaction reduced ,and scar tissue formed. Conclusion: Chemical cholecystectomy is safe and reliable in clinical.

Objective:To explore and sum up diagnostic features and therapy for colorectal carcinoma with hepatic metastasis.Methods:48 cases of colorectal carcinoma with hepatic metastasis treated from Oct.1989 to Oct.1997.Results:The accuracy rates of ultrasound and CT were 18.2%,53.3% respectively.Of the 48 cases,10 cases underwent hepatectomies,10 cases ethanol injected to lives metastatic,8 cases chemotherapy via portal vein synchronously,8 cases intercurrent X-ray,12 cases abandon treatment.Conclusions:Colorectal carcinoma with hepatic metastasis is very difficult to diagnosis before operation,ultrasound and accuracy found on operation were the secure methods for diagnosis of colorectal carcinoma with hepatic metastasis.Hepatectoming is the first way for treating colorectal carcinoma with hepatic metastasis,others way are ethanol inject,chemotherapy via portal vein synchronously,interventional radiotogy,et al.

Objective To investigate the epidemiological characteristics of adverse reaction induced by Chinese activating blood herbal injection. Methods Domestic medicinal periodicals issued during 1972-2011 were searched, and 566 adverse drug reaction (ADR) cases were analyzed by database establishment and statistic method. Results Totally 566 ADR cases involving 16 different kinds of traditional Chinese medicine injection were collected, and 139 cases were related to Fufang Danshen Injection. The incidence of ADR was 51.77%(293 cases) in the male and 48.23%(273 cases) in the female. Average age of patients was (55.01±16.07) years old. The incidence of circulation system damage (206 cases, 23.22%) dominated in ADRs. The number of ADR which occurred within half an hour was 357 cases (64.79%) and the original disease most were cardiovascular and cerebrovascular diseases (384 cases, 67.84%). Conclusion ADR induced by Chinese activating blood herbal injection are commonly seen in middle-aged and elderly people, and often involved circulation system.

Objective To investigate the epidemiological characteristics of adverse drug reactions (ADRs) induced by Chinese herbal injection for tonify, and provide reference for safety evaluation and rational use. Methods The ADR cases that issued on the domestic medicinal periodicals from 1972 to 2011 in China were collected comprehensively to build a database, and analyzed by statistic methods. Results Totally 233 ADR cases involving 7 different kinds of Chinese herbal injection for tonify were collected, in which 86 cases weighted the most were related to Huangqi Injection. Chinese herbal injection for tonify may induce multiple systematic ADRs. The incidence of respiratory damage was 27.0%(80 cases), which was dominated in the ADRs. The incidence of ADRs had no difference between the genders (male was 117 cases, 50.2%, and female was 116 cases, 49.8%), and the average age of patients was (51.40±16.67) years old. ADRs often occurred within half an hour after the start of infusion (64.5%). The diseases of patients mostly were cancer (19.3%), coronary heart disease (15.9%), and hypertension (6.0%), etc. Only 76 cases mentioned the combination therapy, which mainly combined with the drugs of antibiotics, other traditional Chinese medicines and vitamin. Conclusion ADRs of Chinese herbal injection for tonify are always induced by drug combinations, inappropriate medication, and other factors. To use Chinese herbal injection more rational and enhance prevention awareness may be the key to reduce the occurrence of ADRs.

Objective To explore the humidification effects between the humidifiers Venturi high-flow oxygen therapy(HVHF)and the high-flow humidified oxygen therapy in the treatment of patients with tracheotomy after the withdrawal of ventilator,and analyse the humidification performance and effect of airway humidification on the two oxygen therapies hence to provide an objective basis for selection of a humidified oxygen therapy.Methods A total of 146 ICU patients who had tracheotomy and completely withdrawal of ventilator in a general hospital in Shenzhen from July 2020 to December 2021 were randomly divided into trial group(n=73)and control group(n=73).With identical speed of airflow,patients in the trial groups were treated with HVHF and the patients of control group were offered with high-flow humidified oxygen therapy via AIRVOTM2.Data of the two groups were compared at the time points of days 0,2,7 and 14 in terms of absolute humidity(AH),relative humidity(RH),temperature(T)),sputum viscosity,arterial partial pressure of oxygen(PaO2),arterial partial pressure of carbon dioxide(PaCO2),oxygenation index(PaO2/FIO2)and the incidence of pulmonary infection.Results In the study,total of 61 patients in the control group and 72 patients in the trial group completed the high-flow humidified oxygen therapies,due to tubing detachments in 12 and 1 patients in the two groups,respectively.Repeated-Measures ANOVA analysis showed that,in both groups,there was a time effect(P<0.05)between the absolute humidity,relative humidity,temperature of the gas,PaO2,PaCO2,and PaO2/FiO2 at different time points.PaO2 and PaO2/FiO2 in both groups showed interactions at different time points(P<0.05).PaO2 and PaO2/FiO2 in the trial group were better than those in the control group at the time points of days 2,7 and 14(P<0.05).On days 2,7 and 14,the viscosity of sputum in the intervention group was better than that in the control group,and the incidence of pulmonary infection in the trial group was significantly lower than that in the control group(P<0.05).Conclusions HVHF and AIRVOTM2 both exhibit no obvious difference in gas humidification via high-flow humidification oxygen therapy in the patients with tracheotomy after withdrawal of ventilator.However,HVHF is superior to AIRVOTM2 in terms of improving airway humidification and oxygenation as well as reducing lung infection.Therefore,it is suggested that an HVHF is preferable for high-flow humidified oxygen therapy in treating the patients with tracheotomy after the withdrawal of ventilator.
