Chinese Journal of Integrated Traditional and Western Medicine in Intensive and Critical Care 2015;22(5):467-471
Objective To study the effects of Baihu Rensen decoction combined with Fufang Xiebai capsules for treatment of patients with severe pneumonia accompanied by heat-phlegm and sthenic-fu syndrome.Methods A prospective study was conducted; 266 severe pneumonia cases with heat-phlegm and sthenic-fu syndrome admitted into the Department of Respiratory Diseases in Kunshan Hospital Affiliated to Jiangsu University from January 2012 to December 2013 were selected. The patients were randomly divided into a integrated traditional Chinese and western medicine group (136 cases) and a western medicine treatment group (130 cases). Both groups were given basic conventional western medicine according to the disease situation. The integrated traditional Chinese medicine (TCM) was additionally given Baihu Rensen decoction combined with 350 mg of Fufang Xiebai capsules, 3 times a day, 4 grain each time, 7 days constituting a course of treatment. The rate of body temperature descent, the degree of improvement in clinical TCM symptoms, peripheral white blood cell (WBC) count, neutrophil percentage and the situation of endogenous pyrogen production in the two groups were compared.Results After treatment, the body temperature, TCM symptom scores, WBC count and neutrophil percentage were lower than those before treatment, 3 days after treatment these data reached their valley values, and the decrease in level was more significant in the combination group [body temperature (℃): 36.5±0.0 vs. 37.0±0.0, TCM symptom scores: 1.7±0.2 vs. 6.1±0.7, WBC (×109/L): 7.1±0.3 vs. 8.3±0.5, neutrophil percentage: 0.64±0.02 vs. 0.76±0.23, allP < 0.05]. Interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), interferon (IFN-α, IFN-γ), and interleukin-6 (IL-6) level in western medicine (WM) group was respectively marked 1, the levels of IL-1β, TNF-α, IFN-α, IFN-γ, and IL-6 in combination group after treatment for 6 hours were significantly lower than those of WM group, and reached the valley at 12 hours (the relative expression value of each of the above indexes in combination group to each of those in WM group was 0.37, 0.16, 0.21, 0.27 and 0.15 respectively), and had a mild rebound at 24 hours.Conclusion By the addition of Baihu Rensen decoction combined with Fufang Xiebai capsules on conventional basic medicine for treatment of severe pneumonia patients with heat-phlegm and sthenic-fu syndrome, the therapeutic effect is much better.
3.Orthopantomography and cone-beam CT for bone height measurement and simulation in posterior implant region
Chinese Journal of Tissue Engineering Research 2017;21(20):3152-3157
BACKGROUND: Cone-beam CT (CBCT) and orthopantography are two imaging methods mostly used in the preoperative evaluation of dental implantation. CBCT has high cost and low penetration rate, but orthopantography can result in a larger error in the measurement of bone quantity.OBJECTIVE: To compare the accuracy of bone quantity measurement using CBCT and orthopantography, and to evaluate the clinical effect of simulation in posterior implant region. METHODS: 115 implants from 72 patients undergoing implantation of posterior teeth in the Eye & ENT Hospital of Fudan University were selected. The horizontal heights from the top of the alveolar bone to the important anatomic structures (mandibular nerve or maxillary sinus floor) were measured using CBCT and orthopantography and then analyzed statistically. The implantation simulations were performed using Planmeca Romexis3.8 (for CBCT) and Cliniview9.3 (for orthopantography) to compare the differences in stimulated and postoperative horizontal heights.RESULTS AND CONCLUSION: There were significant differences in the measured data between CBCT and orthopantography (P < 0.05), especially in the maxilla (P < 0.01). There were significant differences between the simulated and postoperative results of the two methods (P < 0.05). The average error and standard deviation in orthopantography were larger than those in CBCT. The average error of implantation simulation using CBCT in the maxilla was smaller than that using orthopantography, whereas the error was similar in mandibular simulations. To conclude, CBCT is more accurate for assessing the quantity of bone in posterior implant region, especially in the maxilla. The accuracy of CBCT and orthopantography in implantation simulation needs to be improved.

5.Changes in retinal structure and function of Alzheimer's patients
International Eye Science 2017;17(10):1867-1870
Alzheimer's disease( AD) , a neurodegenerative disease, can result in memory loss, cognitive and behavioral deficits. The pathological hallmarkes are β amyloid plaques and neurofibrillary tangles which lead loss of neurons in brain. As the extension of the central nervous system, retina has a similar tissue anatomy with central nervous system. The β amyloid plaques have also been detected in retina of AD. Furthermore, according to eye examinations of AD patients, we have found the loss of retinal ganglion cells, the attenuation of retinal nerve fiber layer thickness, the smaller changes of macula lutea, the decline of vascular density and so on. And then, there occurs the visual field loss and the decline of contrast sensitivity and so on in AD patients. Thus, the retina has occurred nerve degenerative changes in AD. Meanwhile, there has been proved that the retina nerve degeneration is even earlier than senile plaques formation in brain. In addition, curcumin, a natural and safe fluorescent dye, can be used to label β amyloid plaques in retina. The above suggests that retina can be a window for the early diagnosis of AD.

In order to explore the available sero-diagnotic method for surveillance in basically controlled and controlled areas of schistosomiasis japonica, a 3 years longitudinal investigation of children 6~14 years old with COPT in 5 endemic areas was carried out after being basically controlled for 8~16 years. The results showed that the examination of children with COPT is one of the available serodiagnostic methods of schistosomiasis for surveillance. In all five areas the positive rate of children in this age group was less than 3%, and the circumoval precipitin rate among the positive cases was less than 5%. Therefore, it is indicated that the above mentioned two indexes can be used for sero-surveillance of schistosomiasis japonica.
