Objective To explore the correlation between cognitive ability and motor ability in stroke patients.Methods 30 stroke patients were assessed with the 3 m Timed Up and Go Test (TUG). The anticipated time by patients and the actual time were recorded, and their difference was caculated, named as the cognitive error. They were also assessed with Trail Making Test-Part A (TMT-A). The actual time of TUG, cognitive error and the time of TMT-A was compared among different groups of Brunnstrom stage of lower limb, and their correlation was analyzed. Results There was a significant difference between the actual time of TUG between Brunnstrom stage Ⅲ and Ⅴ (F=4.600, P<0.05). There was positive correlation between actual time of TUG and cognitive error（r=0.844, P<0.01）, time of TMT-A and cognitive error（r=0.508, P<0.01）, time of TMT-A and actual time of TUG （r=0.414, P<0.05）. Conclusion Motor ability of stroke patients can be influenced by deficient attention and motor cognition.

miRNAs are a group of 22 ~25 nucleotides endogenous non-coding RNAs,which regulate gene expression at the post-transcription level by cause the degradation or translational suppression of target mR-NAs.In recent years,studies have demonstrated that miRNAs widely participate in cell differentiation,prolifera-tion,organ development and lipid metabolism,and are closely related to the formation of many kinds of diseases. The biological function of miRNAs and their effects on regulating prenatal and postnatal lung development are reviewed in this paper.

OBJECTIVE:To analyze the rationality of the preventive use of antibiotics in Chinese ophthalmologic patients with type Ⅰ incision.METHODS:By means of retrospective study,a total of 1 273 ophthalmologic cases from 113 hospitals of 2006～2007 from National Monitoring Network of Ministry of Health for Clinical Application of Antibiotic with type Ⅰ incision involving preventive administration of antibiotics via different routes were analyzed.RESULTS:The local administration (eye drops and local injection) was rational on the whole,but the systemic administration (intravenous or oral administration) was irrational to some degree in which the drug grade was on the high side,the antibacterial spectrum was inappropriate,and the medication time was delayed.CONCLUSION:Preoperative local administration and rational use of dosage forms should be emphasized in the preventive use of antibiotics for patients undergoing ophthalmologic surgery.

ObjectiveTo evaluate clinical-pathological features, diagnosis and therapy of gestational trophoblastic tumor (GTT) misdiagnosed as ectopic pregnancy. MethodsFrom 1999 to 2003, a total of 13 patients with GTT misdiagnosed as ectopic pregnancy were retrospectively analyzed. ResultsThe main symptoms were amenorrhea, abdominal pain, irregular vaginal bleeding. Serum beta-human chorionic gonadotrop in(hCG) was measured in 10 patients. Eight had hCG values above 10 000 IU/L; 3 had hCG values above 50 000 IU/L. The lesions of GTT misdiagnosed as ectopic pregnancy were fallopian tube, horn of uterus, peritoneal cavity, greater omentum, recto-uterine pouch. According to standards of the International Federation of Gynecology and Obstetrics(FIGO) the 13 patients were categorized as 6 of stage Ⅰ, 2 of stage Ⅱ, 3 of stage Ⅲ and 5 of stage Ⅳ. Histologically they included 10 cases of choriocarcinoma and 3 of invasise mole. All patients were treated by complete surgical resection combined with subsequent adjuvant chemotherapy. ConclusionsMisdiagnosis leads to delay in therapy with resultant increased morbidity of GTT.Analysis on serial hCG is helpful to differential diagnosis between ectopic pregnancy and GTT.

Objective To observe the therapeutic effects of vitrectomy combined with tissue plasminogen activator(r-tPA) and fraxiparine on bacterial endophthalmitis. Methods Forty pigmented rabbits were randomly divided into experimental and control group with 20 rabbits in each. The left eyes underwent intra-vitreous injection with 105/ml bacteria of staphylococcus epidermidis 0.1 ml. After 8-14 hours, vitrectomy was performed on all of the animals. Fraxiparine with the final concentration of 6 IU/ml was only added to balanced salt solution in the experimental group during the operation, and the extend of intraocular fibrin exudation was observed by slit lamp and indirect ophthalmoscope after the operation. If the exudation occurred on the 1st, 3rd, 7th, 14th and 21st day postoperatively, 125 mg/ml r-tPA 0.1 ml should be injected into vitreous from the 1st day after operation on. Results Fibrin exudation in the pupil area and vitreous body was much less in experimental group than that in the control group after the surgery. Conclusion vitrectomy combined with r-tPA and fraxiparine may alleviate the extent of fibrosis in bacterial endophthalmitis and improve the prognosis.

Objective To explore the clinical diagnostic value of 18 F-FDG PET/CT in patients with kidney neoplasms.Methods Seventy-nine patients (52 males,27 females,average age (57.3 ± 14.1) years),who had definitive diagnosis of kidney neoplasms by 18F-FDG PET/CT and pathological or clinical comprehensive diagnosis in recent five years,were analyzed retrospectively.The diagnosis by PET/CT was made according to the changes of kidney shape,tumor density and FDG uptake (SUVmax).The diagnostic efficacy was calculated.Results Among the 79 patients,70 cases were finally diagnosed as malignant tumors (including 40 cases of renal cell carcinoma,5 cases of renal pelvis carcinoma,8 cases of lymphoma,16 cases of metastatic tumor,and 1 case of renal fascia capsule liposarcoma) and 9 cases of benign tumors (including 7 cases of angiomyolipomas,1 case of renal acidophilic cell adenoma,1 case of metanephric adenoma; the benign tumors did not contain small lipid sample hamartoma cases).The detective rate of kidney neoplasms with 18F-FDG PET/CT was 97.5％ (77/79).For the identification of benign and malignant lesions,the sensitivity of 18F-FDG PET/CT was 92.9％ (65/70),specificity was 7/9,accuracy was 91.1％ (72/79),positive predictive value was 97.0％ (65/67),and negative predictive value was 58.3 ％ (7/12).Conclusions 18 F-FDG PET/CT can detect and identify most of kidney tumors.Whole-body checking and comprehensive evaluation on kidney cancer patients are still the main advantages of PET/CT.

AIM: To investigate the effect of Thymosin ? 1 on the development and matutation of thymocytes. METHODS: The proportion of CD4+CD8+ thymocytes and the expression of smoothened (Smo) of the hedgehog (Hh)-signaling in CD4-CD8-thymocytes were examined to observe the effect of thymosin ? 1 on thymocyte development and matutation. RESULTS: Flowcytometric analysis showed that thymosin ? 1 showed activity at a low dose of 30 ?g/kg, and 30 ?g/kg thymosin ? 1 accelerated the replenishment and maturation of thymocytes according to the expression of Smo of the Hh-signaling in CD4-CD8-thymocytes, the potent negative regulator of proliferative responses. CONCLUSION: Thymosin ? 1 can accelerate thymocyte development from CD4-CD8- to CD4+CD8+.

OBJECTIVE:To provide reference for improving pharmaceutical consultations and the quality of pharmaceutical care. METHODS:The records of pharmaceutical consultations were collected from medication consultation center of Huilong-guan district in our hospital during Jan. 2014-Dec. 2016,and then summarized in terms of consultants composition,consultation form,consulting contents and drugs consulted,while Pareto Diagram was used to analyze the main and minor factors of consult-ing contents. RESULTS:The medication consultation center provided pharmaceutical consultations 20353 cases during 2014-2016. Main consultants were patients (20039 cases,98.5%). A total of 6307 persons were involved,mostly female (3646 persons,57.8%). Face to face was the most common consulting method (19440 cases,95.5%). There were 13 types of consulting contents,among which usage and dosage and guidance for special formulation use were the main factors,including 10392 cases (51.1%) and 3844 cases (18.9%). Among 20353 cases of pharmaceutical consultations,18874 cases of in-volved drugs,and involved 11 categories,mostly respiratory drugs (11756 cases,62.3%). CONCLUSIONS:Usage and dos-age and guidance for special formulation use are the main contents of pharmaceutical consultations in the hospital district. The services of pharmaceutical consultations for patients,physicians and nurses provided by pharmacists can solve the questions on medications,and can promote rational drug use in clinic.

Objective: To study the effect of palate repair operation on middle ear function. Methods: Cleft palate was repaired with double-opposing Z-plasty(DOZ) in 20 cases and with routin method (RM ) in 23 cases. Secretory otitismedia (SOM), high negative pressure (HNP), stapedial reflex(SR) and low acoustic compliance (LAC) were determined 3d before and 6 months after operation respectively. Results: Of the total 86 ears, before operation the persentages of SOM, HNP, SR and LAC were 61. 63, 75. 58, 29. 07 and 65. 15; after operation those were 31.39, 43.02, 66.28 and 33.72, respectively. Of the 40 ears of the cases treated with DOZ the persentages of those were 20.00, 27.50, 72.50 and 25.00) while of the 46 ears of the cases treated with RM those were 41.30, 56.52, 60.87 and 41.30 respectivellly. Conclusion: Middle ear function can be improved by palate repairs surgery, better results may be achieved with double opposing Z-plasty technique.

Southern blotting with a labeled and linearized pUC 19 DNA containing a specific fragment of 0. 24 kb DNA of Plasmodium vivax asexual blood stages (kindly offered by Dr. C. Kidson )was used for further identification of blood samples showing positive reaction by dot-blot hybridization. The results showed that those with positive reaction from patients with P. vivax, with P. falciparum or with fever but with negative microscopic findings were also positive by Southern blotting. It was confirmed that some of those positive with P. falciparum were likely to infect P. vivax at the same time. So did a part of those with fever but negative in the blood films (Figs. 1,2).
