ObjectiveTo analyze the perioperative risk factors of right heart failure (RHF) in human heart transplantation, and to summarize the efficacy of targeted agent especially on pulmonary hypertension.Methods Patients underwent heart transplantation were selected by exclusion criteria : (1) acute heart or other organ failure, or supported by mechanical assist device ; (2) the difference between the body weight of donor and recipient was ＞ 20％ ; (3) the ischemic time of donor was＞ 6 h; (4) acute rejection episode after transplantation; (5) perioperative death.The clinical data of 96 patients were collected, including gender, age, body weight, protopathy, history of heart failure, preoperative systolic pulmonary arterial pressure (SPAP), left ventricle end diastolic diameter (LVEDD), preoperative ejection fraction(LVEF), preoperative blood creatinine, donor ischemic time and preoperative application of 5-PDEs.The diagnosis standard of RHF was established.The risk factors were analyzed through Logistic Regression.Patients were divided into two groups according to the systolic pulmonary arterial pressure (SPAP).In group A, SPAP was ＜40 mm Hg, and in group B with SPAP≥40 mm Hg.The correlation between two groups was tested byχ2 test.ResultsIn the multivariable analysis, age, history of valve disease, length of heart failure,and preoperative SPAP were the risk factors of RHF with the coefficient of 1.051, 1.351, 1.712 and 6.725, respectively.SPAP seems to be the most important risk factor.Coronary artery disease and preoperative application of 5-PDEs-I were the favorable factors with the coefficient of 0.056 and 0.034, respectively.Parameters regarding age, history of valve disease, length of heart failure between the two groups were significantly different.There were no significant differences in gender, body weight, diagnosed as dilated cardiomyopathy or coronary artery disease and other etiologies, preoperative LVEDD, preoperative EF, preoperative blood creatinine, isehemic time and RHF, though the incidence of RHF in group B was higher than in group A (67.6％ vs 45.8％).There was also no statistic difference in using of ECMO and the mortality rate between two groups.ConclusionPreoperative PAP was the main risk factor of the RHF after heart transplantation.Although there was no statistic difference, the incidence of RHF in patients with SPAP≥40 mm Hg was higher than in patients with SPAP ＜40 mm Hg .The application of targeted agent therapy and ECMO may be helpful in treating RHF after heart transplantation.

AIM:To compare the therapeutic effect，adverse reactions and the costs between GM-CSF and G-CSF in treating leucopenia in chemotherapy of cancer.METHODS:Using pharmacoeconomic cost-effectiveness analysis，GM-CSF was compared with G-CSF in treatment of leucopenia in chemotherapy of cancer.RESULTS:The effective rate of GM-CSF was 80％ with an average cost of 1 008 yuan in a therapeutic course，the cost-effective ratio being12.6，and that of G-CSF was 85.7％ with an average cost of 2 304 yuan，the cost-effective ratio being 26.88.CONCLUSION:GM-CSF can effectively treat leucopenia in chemotherapy of cancer，and its cost-effective ratio ia superior to that of G-CSF.GM-CSF is worthy to be used clinically.

?AlM: To evaluate the long - term effects of laser peripheral iridectomy ( LPl ) and trabeculectomy in treating early chronic angle-closure glaucoma.
?METHODS: Ninety-eight patients (102 eyes) with early chronic primary angle-closure glaucoma were randomly divided into two groups. Group A of 50 patients (54 eyes) was treated with LPl and group B of 48 patients (48 eyes) with trabeculectomy. After 3 - 8y of follow - up observation, comparison would be made from the perspectives of postoperative eyesight, intraocular pressure, anterior chamber angle, visual field and cup/disc ratio ( C/D) .
?RESULTS:ln group A, 24 eyes with eyesight declining, 22 eyes with theintraocular pressure>21mmHg (1mmHg=0. 133kPa), 21 eyes with chamber angle synechia >180o, 21 eyes with visual field narrowed, 21 eyes with C/D ratio enlarged. The results of group B for the same items were 10, 5, 4, 4, 4 eyes respectively. The comparative difference was statistically significant (P<0. 05).
?CONCLUSlON:Good effects will be achieved for early-stage chronic angle - closure glaucoma with surgical method. Trabeculectomy is obviously better than LPl for the long-term effects.

Objective　To study the protocol that induces adult rat bone marrow stromal cells (MSCs) to express neuron-specific enolase (NSE) in vitro. Methods　MSCs were preinduced with β-mercaptoethanol for 24 h, and then induced for 5 h. The positive percentages of NSE protein expression were measured by immunocytochemistry SABC staining. Results　After the induction, MSCs displayed neuronal morphologies, such as pyramidal cell bodies and processes which formed extensive networks. The positive percentage of NSE protein expression was (63.7±4.5)%. Conclusions　β-mercaptoethanol may induce adult rat MSCs to NSE-positive cells in vitro.

Objective:To explore the MRI features of cerebral amyloid angiopathy-related inflammation (CAA-ri).Methods:The clinical and imaging data of 12 patients with CAA-ri diagnosed in Affiliated Guizhou Aviation Industry Cor Ltd No 300 Hospital of Zunyi Medical University (9 cases), Xingyi People′s Hospital (2 cases) and Anshun people′s Hospital (1 case) from June 2013 to June 2020 were analyzed retrospectively. There were 3 females and 9 males, aged from 57 to 89 years old, with an average age of 71±10 years. The twelve patients included 5 cases with probable CAA-ri and 7 cases with possible CAA-ri. The duration of the disease ranged from 30 minutes to 2 years. One patient has ApoE ε4/ε4 gene overexpressed. All the 12 patients underwent MRI, including susceptibility weighted imaging in 12 cases, DWI in 10 cases, contrast enhanced MRI (CE-MRI) in 9 cases, MRS in 3 cases, MRA in 7 cases, and perfusion-weighted imaging in 1 case.Results:Imaging features of CAA-ri included encephalopathic, tumoral, classical cerebral amyloid angiopathy(CAA) manifestations. Twelve cases of encephalopathic manifestations showed patchy white matter hyperintensity (WMH) involving U-shaped fibers on T 2 weighted fluid-attenuated inversion recovery sequence (FLAIR), usually asymmetric,with various degree of mass effect, no diffusion restriction on DWI and no enhancement on CE-MRI. One case showed a single tumoral lesion with irregular enhancement on CE-MRI. The classic CAA findings included hemorrhagic lesions (microhemorrhage in 8 cases, lobar hemorrhage in 6 cases, subarachnoid hemorrhage in 3 cases, iron deposition on the brain surface in 7 cases) and ischemic lesions (microinfarction in 1 case, enlarged perivascular space and interlobar space in 4 cases). Follow-up showed lesions absorption and/or new lesion formation in 5 cases. Conclusions:The MRI features of CAA-ri are mainly patchy WMH involving U-shaped fibers on T 2 FLAIR, usually asymmetric, with wandering and alternating features, and inconsistency with clinical manifestations.

Objective To construct the micro-invasive immune rejection monitoring methods with peripher-al blood mononuclear cell gene expression detection and evaluate the clinic rejection estimation value. Methods The SYBR Green Ⅰ was used as fluorescent dye and the GAPDH as house keeping gene control in the quantitatiun RT-PCR technique to observe the 16 immune rejection relative genes expression features after heart transplantation. results were also compared with that of the normal people. Results The 16 immune rejection relative genes expres-sion were no different between normal people and the transplantation recipients before surgery (P>0.05). After heart transplantation the expression of ITGA4, FKB, ILI R-2 up regulated and the level of PF4、ITGAM、TGFβ1、 RHOU down regulated. The results were similar with the clinic observation that the immune rejection often occurs in the first 3 months after heart transplantation. It implied that these 7 genes may play an important role in the acute im-mune rejection after transplantation. Conclusion The real time quantitation RT-PCR methods were constructed suc-cessfully to detect the multiple immune relative genes expression and is of chnic applicable.

Field avian infectious bronchitis virus (IBV) designated as JS/9 5/03, which was isolated from Jiangsu province of china, was cultivated in chicken emb ryo. It's single strain RNA was extracted from purified virus and worked as temp late of reverse transcription polymerase chain reaction (RT-PCR), a pair of pri mer designed according to megalign results of published IBV sequences in Genbank was used to amplify the neucleocapsid gene, the RT-PCR product was sequenced d irectly. Sequence analysis revealed that the sequence of JS/95/03 is most homolo gized with that of M41 strain.
