Methods Forty- seven children with moderate or severe persistent asthma were treated with inhalation of the fluticasone pro-pionate and salmeterol. The PEF value and the mark according the symptom of asthma before and after treatment( week and month respectively) were recorded. At the same time the days of treatment the patient with the short - ?2 - agonist in the first week and the forth week respectively were noted. The subjective feeling and accident of patients also should be paid attention. Results There was significant difference (P

Objective To investigate the influence of thiamine deficiency(TD)at early pre- pathological lesion stage on cognitive function and the correlation between cognitive dysfunction and hippocampal neurogenesis.Methods TD mouse model was prepared by feeding a thiamine-depleted diet. Learning and memory functions of TD mice were tested with Y-maze.Hippoeampal neurogenesis was studied with bromodeoxyuridine(BrdU),proliferative cell nuclear antigen(PCNA),and Doublecortin(Dcx) immunohistochemical staining on the 7th(TD7),9th,14th and TD25th day.Results TD9 mice without pathological impairment and cholinergic nerve degeneration needed more times of training(22.3?2.2)in the learning test of Y maze compared with the controls(13.5?3.5).Correspondingly,the numbers of BrdU-positive ceils and the immunoreactivity of Dcx decreased significantly in the TD9 mice(19.8?0.4, 1537.2?50.2 vs 23.9?0.3,2688.9?127.9 pixels/mm~2).Thiamine re-administration reversed the declined hippocampal neurogenesis:the number of BrdU-positive cells was 23.6?1.9 and Dcx immunoreactivity was 2052.3?269.6 pixels/mm~2:the impaired learning ability was simultaneously restored,with the number of total training trial being 16.8?0.5.Conclusion The decreased hippocampal neurogenesis contributes to retarded learning ability at early pre-pathological lesion stage of TD.

· AIM: To inspect and compare the functional vision of an aspheric intraocular lens (Tecnis) with those of conventional monofocal silicone and acrylic intraocular lens and multifocal intraocular lens (Array).· METHODS: The IOLs were tested in the eye model, which was designed to be optically equivalent to the theoretical eye model. The eye model is a combination of a spherical photographic lens with 35mm focal length ( IOL put in a water cell)and a charge coupled device (CCD) camera. The images constructed by the lenses are observed on a monitor of personal computer and the contrasts of the images are analyzed by using commercial image processing software.· RESULTS: The modulation transfer function of the eye model equals the scale produced by the theoretical eye model. The images constructed by changing the diameter of aperture stop and IOL.· CONCLUSION: The proposed eye model is useful for testing functional vision and for inspecting differences of intraocular lens.

OBJECTIVETo observe the effect of Chinese drugs for strengthening Pi, harmonizing Wei, and dispersing blood stasis (CDSPHWDBS) on the expression of gastric mucosal heat shock protein 70 (HSP70) in chronic atrophic gastritis (CAG) patients.

METHODSA total of 100 CAG patients were assigned to the control group and the treatment group by random digit table, 50 in each group. Patients in the control group took Folic Acid Tablet 10 mg each time, 3 times per day. Those in the treatment group took CDSPHWDBS, 100 mL each time, once per day. The treatment course was 6 months for all. Clinical symptoms and signs, endoscopic and histopathological changes were observed before and after treatment in the two groups. The expression of gastric mucosal HSP70 in CAG patients was determined using SP immunohistochemistry. Data were collected by HPIAS-1 000 pathological graphic analysis system, and its expression semi-quantitatively analyzed.

RESULTSThe total effective rate of clinical Chinese medical symptoms and signs was 88. 0% (44/50 cases) in the treatment group and 56. 0% (28/50 cases) in the control group, with significant difference between the two groups (P <0. 01). The improvement rate of endoscopic manifestations such as congestion and edema, erosion, bile regurgitation, pale gastric mucosa, exposed blood vessels, particles proliferation in the treatment group were superior to those in the control group (P <0. 05). The total effective rate of atrophy was 80. 0% (40/50 cases) in the treatment group and 54. 0% (27/50 cases) in the control group, with significant difference between the two groups (P<0. 01). The effective rate of intestinal metaplasia was 75. 0% (12/16 cases) in the treatment group and 33.3% (5/15 cases) in the control group, with significant difference between the two groups (P < 0. 05). The optical density value of gastric mucosal HSP70 was significantly elevated in the two groups after treatment (both P <0. 05). It was higher in the treatment group than in the control group after treatment with significant difference (P <0. 01).

CONCLUSIONCDSPHWDBS had obvious effect in treatment of CAG and could improve pathological changes of precancerous lesions possibly by promoting the expression of gastric mucosal HSP70 in CAG patients.

OBJECTIVETo explore the effect and the mechanism of Danhong Injection (DI), Ligustrazine Injection (LI), and adsorbable biomembranes in preventing the adhesion of tendons and tissues.

METHODSTotally 120 patients all suffering from simple flexor digitorum tendon rupture on the hand zone two damaged by sharp weapons were randomly assigned to Group A (Dikang adsorbable biomembrane), Group B (Tianxinfu adsorbable biomembrane), Group C (Tianxinfu adsorbable biomembrane + Ligustrazine group), and Group D (Tianxinfu adsorbable biomembrane + DI group) in accordance with random digit table, 30 cases in each group. Indicators such as total active movement (TAM) of the hand tendon, Minnesota manual dexterity test (MMDT), and finger flex strength test (FFST) were observed.

RESULTSThe TAM and the favorable rate were higher in Group C and D than in Group A and B at post-operative 4 and 8 week (P < 0.05, P < 0.01). There was no statistical difference between Group C and D (P > 0.05). Each index of MMDT was lower in Group C and D than in Group A and B (P < 0.05). There was no statistical difference in FFST among all the 4 groups (P > 0.05).

CONCLUSIONSCombined application of LI or DI with Tianxinfu adsorbable biomembranes could effectively prevent the adhesion of tendons. DI showed equivalent effect as LI did. Besides, the combined application was superior in preventing adhesion to using Xintianfu adsorbable biomembrane or Dikan adsorbable biomembrane alone.

Objective To evaluate the situation of musculoskeletal imaging research at home and abroad and the disparity and consistency between them.Methods Statistic analysis was done with the musculoskeletal articles published in those journals during the last decade,including Chinese Journal of Radiology,Journal of Clinical Radiology,Radiology,American Journal of Roentgenology(AJR)and the British Journal of Radiology(BJR).Results The development of museuloskeletal imaging research was very imbalaneed among different areas and hospitals in China.The rate of clinical research treatise and imaging technique articles at home was 76.3%(357/468)and 10.0%(47/468),respectively,while that was 75.7%(731/966)and 10.8%(105/966),respectively abroad.The rate of MR image technique articles in China was lower than that abroad.The rate of articles on basic research at home and abroad was 5.3%(25/468)and 7.9%(76/966),respectively.The rate of articles about museuloskeletal imaging simply using CT or MR at home was 20.1%(94/468)and 29.7%(139/468),respectively,while that was 5.1%(49/966)and 60.4%(548/966),respectively abroad.The rate of articles about interventional therapy and synthetic imaging at home was 9.2%(43/468)and 29.3%(137/468),respectively,while that was 4.7%(45/966)and 22.5%(217/966),respectively abroad.With regard to the diseases category,the research focused on the bone tumors and the tumor-like disease in China,while in other countries,the research focus had been diverted to the trauma of bone and joint,and the anatomy and disease of muscle and ligament,which was unsatisfactory in China.More focus had been put on imaging anatomy, cartilage disease and osteoporosis in other countries than in China.The research on the radiation dosage the subject received in the examination,the apphcation of Micro-CT and Micro-MR to musculoskeletal imaging was developed in other countries,but it had not been reported in China.Conclusion Although great success has been achieved in the research of musculoskeletal imaging in the last decade,there is still much disparity comparing with other countries,and the research is very imbalanced among different areas and hospitals in China.We should emphasize the application of MRI to musculoskeletal system and pay more attention to the basic research and imaging anatomy research,especially the research on ligament,muscle and cartilage.

Objevtive To explore the microsurgical methods for resecting the tumors of the third ven- tricle and discuss the anatomic foundation of mircrosurgical methods.Methods Twelve patients with tumors of third ventricle were operated on via approach of transcallosum interfornix.Pathologic diagnoses included eight craniopharyngiomas intruding the third ventricle,two gliomas in medial thalamus,one ependymoma and one teratoma.Results Total removal in microscope of the tumors were achieved in 10 cases and subtotal re- moval in 2 cases.The percentage of total resections achieved to 83.3%.Seven of eight craniopharyngiomas were totally resected and the postoperative MR indicated no remanent or recurrent tumors.No death occurred in all cases and the recent complications which were disappeared after one or two weeks' management mostly included polydipsia,diuresis and electrolyte disturbances.Long termed complications included two hydren- cephalus and two spontaneously absorbed subdural fluidifies ventricle-abodminal shunt was performed in one case.The time of follow-up continued were between two months to two and a half years.One subtotal resected craniopharyngiomas was relapesed in eight months,one glioma in thalamus was relapesed in one year and in the remanent ten cases nine can live normally and one can live with self-care.Conclusion Transcallosum interfornix approach for microsurgically removing the third ventricle tumors reached the third ventricle through the rudimental tissue space of embryonic tissue.It can provide a slight trauma,a quite large operative field, euthyhoria for operating.We can use this appoach to resect the tumors located in all directions in the third ven- tricle.The percentage of total resection was large and few complications occurred.

Abstract: To analyze the clinical, therapeutic and laboratory characteristics of disseminated cryptococcosis caused by Cryptococcus neoformans invading the blood stream in patient with liver cirrhosis and splenectomy. A 30-year-old male underwent splenectomy plus pericardial devascularization due to "splenomegaly and hypersplenism" in March in 2016. The patient had intermittent fever after operation for many times, and successively accompanied with back pain, left lower limb abscess and right hip pain. The highest body temperature was 39 ℃. CT and MRI revealed the lung lesion and multiple bone destruction. During that period, the effect of antibiotics was not good. On April 19th, 2017, Gram's stain, India ink stain, API 32C, Vitek 2 Compact, ribosomal ITS and IGS sequence analysis were performed to identify the strain isolated from the pus and blood stream. The serum of the patient was detected for cryptococcal antigen. Antifungal susceptibility test was used to determine drug sensitivity and minimum inhibitory concentration (MIC). The Cryptococcus neoformans isolated from fresh pus specimen showed a prominent, thick capsule after India ink stain. The colonies isolated from pus and blood stream were identified Cryptococcus neoformans using API 32C, Vitek 2 Compact, and sequence analysis of rDNA ITS and IGS. Cryptococcal capsule antigen was positive. The minimal inhibitory concentrations of 5-Flucytosine, amphotericin B, fluconazole, itriconazole, voriconazole against the isolate were <4 μg/mL, <0.5 μg/mL, 4 μg/mL, ≤0.25 μg/mL, 0.125 μg/mL respectively. The patient was initially treated with intravenous amphotericin B and flucytosine. After anti-Cryptococcus treatment for two months, the patient clinically improved, and the lesions were reduced on a follow-up CT scan. The patient made a full functional recovery after treatment for six months. Cryptococcosis has hidden onset, atypical clinical symptoms and lack of specificity. Blood stream is the main channel for Cryptococcus to spread and involve many organs of the whole body, including skin, bone and so on. Therefore, early use of blood culture to monitor blood flow dissemination, actively removing the primary focus and cutting off the infection route in time and carrying out effective anti-Cryptococcus treatment are conducive to the patient's early recovery.

In view of that there is no report of west Nile virus infection cases in our country, evaluation the self-prepared anti-WNV-IgG diagnostic ELISA kit should be employed with the establishment of the serum sample panel collected from the entry personnel. All individuals of entry personnel were traveled from epidemic area of infectious west Nile disease. In our study, the serum samples were both detected by self-prepared anti-WNV-IgG diagnostic ELISA kit and the FDA certified kits ,which are FOCUS West Nile Virus IgG Dxselect and Panbio Dengue IgG Capture ELISA kits. The self-prepared kit and FDA certified kits were compared and assessed simultaneously. Furthermore, the specificity, repeatability and stability of the kits were also evaluated. The results indicated that no significant difference of detective rates (35. 6% for self-prepared kit vs. 32.5% for FOCUS kit, χ2 = 3. 05, P > 0.05) and good consistency (Kappa = 0.8372) between the self-prepared kit and FDA certified kits. Also, the positive coincidence rate, the negative coincidence rate and the total coincidence rate were calculated as 91.18%, 95.34% and 92.66%, respectively. The laboratory self-developed kit presented similar quality as the counterpart kits with FDA certificate. The development of our self-prepared anti-WNV-IgG diagnostic ELISA kit will provide technical support for the prevention and control of west Nile virus entry.
