Of the 411 hepatitis with severe jaundice admitted, 124 ( 30. 17%) had head perspiration. Based on Zhang Zhongjing's etiologic - pathogenic conception, 102 cases of such patients were treated by the principle of cooling and activating blood, benefitting Qi and Yin. 89 cases had jaundice eliminated, 13 cases had residual jaundice. All 22 cases of chronic severe hepatitis survived. Of them, 9 early stage cases were all survived, 7 of the 8 cases of intermediate stage survived, only 1 out of 5 cases of late stage survived.

Alzheimer′s disease(AD)is one of the most common causes of cognitive impairment.“Aβhypothesis”and“tau protein aggregation hypothesis”are two representative hypotheses in relation to AD pathology. But recently,therapeutic strategy target?ing on reducing Aβdeposition failed in clinical trials. On the other hand,as the phosphorylation of tau protein is regulated by multiple upstream kinases,inhibition of a single kinase usually cannot effectively suppress the aggregation of the tau. While blocking multiple kinases at the same time will produce serious side effects. Currently,targeting on Aβand tau protein get into awkward situations. In view of this,researchers are looking for new drug targets for improving cognitive function. Phosphodiesterase 4(PDE4 4)is an enzyme responsible for the hydrolysis of cAMP in the body. There are four subtypes for PDE4,and PDE4A,B and D are highly expressed in the central nervous system. Inhibition of PDE4 causes activation of cAMP/PKA/CREB/BDNF signal pathway,which is beneficial for the strengthening and consolidation of learning and memory. This review will focus on the most recent evidence regarding the role of PDE4 in learning and memory.

Objective To investigate the water equivalent of two solid water phantoms.Methods The X-ray and electron beam depth-ion curves were measured in water and two solid water phantoms,RW3 and Virtual Water.The water-equivalency correction factors for the two solid water phantoms were compared.We measured and calculated the range sealing factors and the fluence correction factors for the two solid water phantoms in the case of electron beams. Results The average differenee between the measurled ionization in solid water phantoms and water was 0.42%and 0.16%on 6 MV X-ray(t=-6.15.P=0.001and t=-1.65,P=0.419)and 0.21%and 0.31%on 10 MV X-ray(t=1.728,P=0.135 and t=-2.296,P=0.061),with 17.4%and 14.5%on 6 MeV electron beams(t=-1.37.P=0.208 and t=-1.47,P=0.179)and 7.0%and 6.0%on 15 MeV electron beams(t=-0.58.P=0.581 and t=-0.90,P=0.395).The water-equivalency correction factors for the two solid water Dhantoms varied slightly largely,F=58.54,P=0.000 on 6 MV X-ray,F=0.211.P=0.662 on 10 MV X.ray,F=0.97.P=0.353 on 6 MeV electron beams,F=0.14,P=0.717 on 15 MeV electron beams.However,they were almost equal to 1 near the referenee depths.The two solid water phantoms showed a similar tread of Cpl increasing(F=26.40,P=0.014)and hpl decreasing(F=7.45,P=0.072)with increasing energy.Conclusion The solid water phantom should undergo a quality control test before being clinical use.

Objective To evaluate the modified Physical and Operative Severity Score for the Enumera-tion of Mortality and Morbidity (POSSUM) in predicting the postoperative morbidity in patients with fractures of the pelvis and acetabulum. Methods The clinical data of 94 patients with pelvic and acetabular fractures were retrospectively analyzed. Their postoperative prognosis during hospital stay was evaluated with the POSSUM scoring system modified according to the features of orthopedics and pelvic and acetabular fractures. The peritoneum in-fection in the severity index of operation was replaced by operative approach, the several operations at one time by operative duration, and the cancer by the associated injury. The size and type of operation were made into 4 grades with corresponding orthopedic scores. The scores were compared between the complication group and the non-complication group. The receiver operator characteristic (ROC) curve was drawn to describe the coincidence degree, define the cut points, and evaluate its predicting capability. Results The mean preoperative physi-ological score (PS) and operative severity score (OS) in the complication group (38 cases) were significantly higher than those in the noncomptication (56 cases) (17.26 ± 2.84 vs 16.04 ± 2.77; 19.50 ± 5. 14 vs 13.00 ±3.81 ) ( P ＜ 0.05) . In the modified POSSUM, the area under ROC curve was 0. 856, the cut point 43%, sen-sitivity 73.68%, specificity 80. 36%, and coincidence degree 77.66%. Conclusions Since the modified POSSUM scoring system has a high capability of predicting postoperative morbidity for fractures of the pelvis and acetabulum, it can be helpful for surgeons to lower operative risks and ensure safety in operation. When the score is higher than the cut point, the risk is too great for an operation. Therefore, the fracture should be treated non-operatively or mini-invasively until the score is lower than the cut point.

Objective To explore the clinical significance of experimental index in incomplete Kawasaki disease (iKD).Methods Eighty-eight cases of KD were reviewed,including iKD 36 cases (iKD group),complete KD(cKD) 52 cases (cKD group).The 88 cases were divided into traditional criterion group (43 cases) and supplement criterion group (45 cases).The experimental indexes of supplement criterion were compared between iKD group and cKD group.Results The rate of coronary artery lesion (CAL) in iKD group was significantly higher than that in cKD group [50.00％(18/36) vs.26.92％(14/52),P ＜ 0.05].Plasma NT-proBNP and cardiac troponin Ⅰ (cTnI) in CAL children (32 cases) in early were significantly higher than those in non CAL children (56 cases) [(468 ± 141) ng/L vs.(379 ± 120) ng/L and (0.95 ±0.22) μg/L vs.(0.49 ±0.15) μg/L,P ＜0.01].The diagnosis rates of KD in the 5th,7th,9th day in supplement criterion group were significantly higher than those in traditional criterion group [64.44％(29/45)vs.25.58％(11/43),84.44％ (38/45) vs.46.51％ (20/43),93.33％(42/45) vs.58.14％ (25/43),P ＜ 0.01].There was no statistical significance between iKD group and cKD group in C reactive protein,erythrocyte sedimentation rate,albumin,alanine aminotransferase,platelet,white blood cell,NT-proBNP and cTnI etc (P ＞ 0.05).There was no statistical significance between iKD group and cKD group in the positive rate of each experimental index (P ＞ 0.05).Conclusions There are some changes of supplement experimental index in acute phase of KD,but there is no statistical significance between iKD and cKD.Plasma NT-proBNP and cTnI are significantly higher in early KD.
