Intravenous recombinant tissue plasminogen activator (rtPA) thrombolysis is the most effective therapy for acute ischemic stroke. Its most serious complication is symptomatic intracerebral hemorrhage. The overall incidence reported in the literature is 6%. It is correlated with the wascular injury and the increased vascular permeability. Some clinical features, imaging and laboratory tests can predict the risks of the complication of intracerebral hemorrhage. The mortality and disability are very high in patients with the complications of intracerebral hemorrhage after thrombolytic therapy, and their prognosis is very poor. This article reviews the classification, incidence, predictive factors, and prognosis of intracerebral hemorrhage after thrombolysis.

Objective To investigate the major clinical manifestations and their effect on prognosis in patients with posterior circulation stroke (PCS).Methods The clinical data of 129 consecutive hospitalized patients with acute PCS confirmed by clinical and imaging were registered prospectively,and they were followed up for 3 months.The patients were divided into a good prognosis group (modified Rankin scale [ mRS] score ≤ 2) and a poor prognosis group (mRS score ≥ 3) according to their mRS scores.Results 90.7％ patients had 4 to 12 symptoms and signs,only 1 presented an isolated symptom.The most common symptoms and signs were unilateral.Crossed paralysis (1.6％) or quadriplegia (0.8％ ) was rare.Univariate analysis showed that the symptoms of unilateral limb weakness (relative risk [RR] 1.262,95％ confidence interval [ CI] 1.030-1.546; P =0.030),slurred speech (RR 1.434,95％CI 1.133 - 1.816; P=0.004),dysphagia (RR 2.216,95％ CI 1.131 -4.341; P =0.017),and the signs of decreased unilateral muscle strength (RR 1.288,95％ CI1.047-1.583; P=0.021),central facial/tongue paralysis (RR 1.467,95％CI 1.164- 1.850; P=0.002),dysarthria (RR 1.468,95％CI 1.154- 1.867; P=0.002),ocular motor dysfunction (RR 3.073,95％CI1.346 - 7.017; P =0.005),and conscious disturbance (RR 5.736,95％ CI 1.268 - 25.946; P =0.023) were the risk factors for poor prognosis,while ataxia (RR O.478,95％ CI 0.284 -0.804; P =0.002) was associated with good prognosis.Multivariate logistic regression analysis demonstrated that after adjusted for all risk factors,the baseline National Institutes of Health Stroke Scale (NIHSS) (odds ratio [ OR] 1.513,95％ CI1.107-2.066; P=0.009),dysarthria (OR,7.11,95％ CI 1.207-41.877; P=0.030),ocular motor dysfunction (OR 8.653,95％ CI 1.230- 60.887; P=0.030),and large-artery atherosclerotic stroke (OR5.482,95％ CI 1.008 -29.803; P =0.049) were the independent risk factors for poor prognosis in patients with PCS,while ataxia (OR 0.251,95％ CI 0.067- 0.941; P=0.040) was independently associated with good prognosis of the patients.Conclusions The clinical manifestations in patients with PCS are complex,the majority of their symptoms and signs are unilateral.Most of the patients showed a variety of symptoms,and the isolated symptoms axe rare.Some symptoms and signs may indicate the prognosis of patients.

To study on the association between the different levels of C-peptide of type 2 diabetes and colorectal adenoma and cancer risk.We detected the concentration of serum C-peptide in 45 type 2 diabetes who were diagnosed as colorectal adenoma and cancer.It showed that serum C-peptide level was higher in type 2 diabetes with colorectal adenomas and cancer than without colorectal adenomas and cancer.The serum C-peptide level may have relationship with colorectal adenomas and cancer.

OBJECTIVE:To observe the effect of electrolytes on the stability of fat emulsion in ALL IN ONE.METHODS: The size of fat emulsion particulates was observed under microscope in 400 - fold magnification.The oil - water demixing was observed with naked eye.RESULTS:The higher the concentration of electrolytes,the stronger the influence on the fat emulsion particulates aggregation and the easier the oil - water demixing appeared.The influence of bivalent ions was stronger than that of monovalent ones.The longer the mixture stored the stronger the influence.CONCLUSION:In order to keep the stability of ALL IN ONE,the concentrations of electrolytes should not be too high,and ALL IN ONE must be used up in 24 hours.

Objective To study the effect of pioglitazone on the differentiation and function of rat osteoclast-like cells (OLC), and to probe the relationship between activated PPARγ2 and osteoclasts. Methods On day 1 of OLC formation from nonadherent bone marrow ceils (BMC) obtained from rats induced by M-CSF and receptor activator of NF-кB ligand (RANKL), 1, 5 and 10μmol/L pioglitazone hydrochloride was added. RT- PCR was performed to determine the mRNA expressions of PPARγ2 and receptor activator of NF-кB (RANK) on day 3, 5 and 7 during incubation, the number of tartrate-resistant acid phosphatase (TRAP)-positive cells,the number of bone resorption pits and the ratio of its area on dentin slice were counted, the activity of TRAP and the mean fluorescence intensity of integrin β3 (CD61) of OLC were also measured. Results (1) The effect on the differentiation of OLC: The addition of pioglitazone at the start of the culture period induced a dose-dependent decrease in TRAP-positive OLC and the activity of TRAP (P < 0.01 or P < 0.05) ; the mRNA expression of PPARγ2 was up-regulated by 5 and 10 μmol/L pioglitazone in the early stage of incubation and attenuated with thematuration of OLC on the contrary, however, the expression of RANK was down-regulated by 5 and 10 μmol/L piolitazone in every stage of incubation (P < 0.05 or P < 0.01), combined with decrease in TRAP-positive OLC from day 3 by 10 μmol/L pioglitazone. (2) The effect on the function of OLC: the number of bone resorption pits and the ratio of its area on dentin slice were decreased in groups of 5 and 10 μmol/L pioglitazone (P < 0.01 orP < 0.05), no obvious change was noted in the group with 1 μmol/L pioglitazone compared with the control group; the mean fluorescence intensity of CD61 were down-regulated in groups of 5 and 10 μmol/L pioglitazone (P < 0.05 or P <0.01). Conclusion Activation of PPARγ2 pathway by pioglitazone could partially inhibit differentiation and function of OLC derived from rat BMC.

Objective:To investigate the epidemiological characteristics and current status of surgical management for esophageal cancer in China.Methods:A national database was setup through a network platform. The clinical data of esophageal cancer treated by surgery was collected from 70 major hospitals in China between January 2009 and December 2014.Results:Complete data of 8 181 cases of esophageal cancer patients who underwent surgery were recorded in the database and recruited in the analysis. Among them, 6 052 cases were male and 2 129 were female, the average age was 60.5 years.The epidemiological investigation results showed that 148 cases (1.8%) had history of psychological trauma, 7 527 cases (92.0%) were lower social economic status, 5 072 cases (62.0%) were short of fresh vegetables and fruits, 6 544 cases (80.0%) ate rough food frequently, 3 722 cases (45.5%) drank untreated water directly from lake or river or shallow well, 3 436 cases (42.0%) had a unhealthy eating habit, including habits of eating food fast (507 cases, 6.2%), eating hot food or drinking hot tea/soup (998 cases, 12.2%), eating fried food (1 939 cases, 23.7%), 4 410 cases (53.9%) had the habits of smoking cigarettes and 2 822 cases (34.5%) drank white wine frequently.The pathological results showed that 7 813 cases (95.5%) were squamous cell carcinoma, 267 cases were adenocarcinoma (3.3%), 25 cases were adenosquamous cell carcinoma (0.3%) and 50 cases were small cell carcinoma (0.6%). A total of 1 800 cases (22.0%) received preoperative neoadjuvant therapy due to locally advanced disease or difficulty of resection. The esophagectomies were performed through left thoracotomy approach in 5 870 cases (71.8%), through right chest approach in 2 215 cases (27.1%), and the remain 96 cases (1.2%) received surgery though other approaches.A total of 8 001 cases (97.8%) underwent radical resection, the other 180 cases (2.2%) received palliative resection. The 30-day postoperative mortality rate was 0.5%, the overall ≥ grade Ⅱ postoperative complication rate was 11.6% (951 cases). The 1-yr, 3-yr, and 5-yr overall actual survival rates were 82.6%, 61.6%, and 52.9%, respectively.Conclusions:The data analysis of the national database for esophageal cancer shows that bad eating habits or eating rough food without enough nutrients, lower social and economic status, drinking white wine and smoking cigarettes frequently may be correlated with tumorigenesis of esophageal cancer. However, strong evidences produced by prospective observation studies are needed. Overall, the long-term survival of esophageal cancer patients has been improved gradually due to the application of advanced surgical techniques and reasonable multimodality treatment.

From the perspective of state differentiation and treatment， it is believed that the pathogenesis of acute respiratory distress syndrome （ARDS） is that evil poisons injured the lungs， and the lung qi suddenly collapsed， then blocked and exhausted， and the qi failure to control blood and liquid， then the fluids overflow outside the vessels， and damp phlegm， stasis， and toxins became knotted up in the body， which ultimately leads to qi dysfunction， and a series of symptom arise， so qi impairment is the principal mechanism of ARDS. A combination of Chinese and Western medicine was proposed to treat ARDS by combining tangible qi and intangible qi， using Chinese herbal medicine to boost qi and relieve collapse， percolate and drain dampness with bland medicinals， resolve toxins and dissolve stasis， and regulate qi， and combining with Western medicine to assist qi circulation to improve qi's consolidation， propulsion， and transformation， so as to make the evil qi go away， the positive qi restored， the viscera qi circulated， qi， blood， yin， and yang connected， and the activities of life maintained， and thus to achieve the goal of treating ARDS by integrated Chinese medicine and Western medicine.
