Objective To discuss the efficacy of intravesical instillation of sodium hyaluronate for the treatment of cystitis glandularis after transurethral resection.Methods 85 patients (9 male and 76 female,age range 37-70 years,mean age 51) who were diagnosed as CG in China-Japan Union Hospital of Jilin University underwent transurethral resection.After the operation they were divided into three groups randomly according to different intravescal instillation:sodium hyaluronate for group A,epirubicin for group B and no medicine for group C.The group A started to instill with sodium hyaluronate 40mg once a week for four weeks,and then once a month for four months.The group B did the same way of intravesical instillation of epirubicin.All the patients were followed-up for 12 months.The cystoscopy was done every three months to detect recurrence and the clinical symptom score was evaluated at 1,3,6 and 12 months.Results No patients in group A treated by sodium hyaluronate relapsed but 6 cases and 9 cases in group B and group C respectively.Recurrence rate of group A is significant low compared with group B and C (P ＜ 0.05).The scores of clinical symptom score appendix after 1,3,6 and 12 months for group A were (3.18 ± 1.44),(1.29 ±0.66),(1.25 ±0.65) and (1.21 ±0.63),respectively.It was (3.37 ±1.62),(3.33 ±1.59),(1.37±0.74) and (1.30±0.61) for group B,and (3.47±1.81),(3.40±1.52),(3.27±1.41) and (3.23 ± 1.19) for group C.Compare the score of clinical symptom in the same group,there were significant differences for the score after 3 months compare with the score after 1 month in group A (P ＜ 0.05).But in group B,the significant differences showed after 6 months (P ＜ 0.05).There was no significant difference in group C (P ＞ 0.05) in the whole year.Conclusions Intravesical sodium hyaluronate therapy can effectively decline the recurrence rate of cystitis glandularis after transurethral resection.It could also significantly improve the urinary tract symptoms.

Objective To evaluate the overall effectiveness of microsurgery for elderly pituitary adenomas,and to select the optimal surgical approaches for this type of tumor. Methods Microsurgical operation was performed on 190 patients with elderly pituitary ademomas,and these patients were retrospectively analysed. The 190 cases were divided into transsphenoidal group and transcranial group with a comparison analysis of respective removal percentage,postoperative complication and follow-up. Results In the transsphenoidal group with 158 cases,total removal were performed in 112 cases (71.0%),subtotal removal in 30 cases,partial removal in 16 cases. In the transcranial group with 32 cases,total removal were performed in 8 cases (25.0%),subtotal removal in 16 cases,partial removal in 8 cases. Conclusions Transsphenoidal approach was characterized by shorter hospitalization period,less therapeutic charges and better postoperative quality of life and it should be of choice for the treatment of the elderly pituitary adenomas.

Objective To investigate the prevalence of thyroid nodules among residents of Ningbo City and to explore the risk factors for thyroid nodules.Methods Totally 3 596 residents aged 6-70 were selected by multistage stratified cluster random sampling in Ningbo City,2011.Thyroid ultrasound examination was performed in all participants,while salt iodine and urinary iodine were measured.Possible risk factors for thyroid nodules were analyzed by single factor and multi-factor logistic regression.Results The prevalence rate of thyroid nodules in residents of Ningbo City was 22.66％ (815/3 596),with standardized prevalence rate of 17.69％.Female [(odds ratio (OR) =2.06,95％ confidence interval (CI) =1.74-2.43],groups of aged 18-(OR =3.42,95％ CI =1.22-9.61),aged 40-(OR =13.06,95％ CI =4.80-35.51),aged 65-(OR =16.67,95％ CI =5.97-46.54) and occasional consumption of seafood habits (less than twice per week,OR =1.23,95％ CI =1.02-1.49) were significant associated with thyroid nodules.Conclusions There is no link Letween iodine nutrition and thyroid nodules.It is demonstrated that female and aged ≥ 18 groups have higher risk of thyroid nodules; frequent consumption of seafood seems to be a protective factor.

Objective To investigate the iodine nutritional status,thyroid function and the prevalence of thyroid nodules of residents using non-iodized salt in Ningbo City,Zhejiang Province.Methods In 2011,using typical sampling method,6 villages/communities consumption of non-iodized salt were selected as study fields and residents aged 6-70 were selected as study subjects in Ningbo.Urinary iodine detection,thyroid ultrasound examination and tests of thyroid function [free triiodothyronine (FT3),free thyroxine (FT4),thyroid stimulating hormone (TSH),thyroid peroxidase antibody (TPOAb) and thyroglobulin antibody (TgAb)] were performed in all participants.Urinary iodine concentration (UIC) was determined by arsenic cerium catalytic spectrophotometry,and thyroid function was monitored by chemiluminescence method.Results A total of 1 177 residents agreed to participate in the study,482 were male,and 695 were female (including 2 pregnant women).The participants' mean age was (48.54 ± 13.98) years.The median UIC in all participants was 90.36 μg/L,and the proportions with a UIC ＜ 100μg/L was 56.07％ (660/1 177).Furthermore,the median UIC in male was 97.05 μg/L and in female was 83.84 μg/L,there was a significant difference in UICs between male and female (Z =-2.99,P ＜ 0.05).Similarly,significant difference in UICs was observed among age groups (x2 =99.34,P ＜ 0.01).Among the participants,19.88％ had thyroid nodules,with standardized prevalence rate of 13.95％.Furthermore,in male,11.83％ had thyroid nodules,with standardized prevalence rate of 8.11％,and in female was 25.47％,with standardized prevalence rate of 19.83％,there was a significant difference in the detection rate of thyroid nodules between male and female (x2 =33.25,P ＜ 0.01).Likewise,significant difference in the detection rate of thyroid nodules was observed among age groups (x2=49.65,P＜ 0.01),and there was a positive and significant correlation between the detection rate of thyroid nodules and increasing age (x2trend =44.22,P ＜ 0.01).Conclusions The residents who using non-iodized salt in Ningbo City are in the status of iodine deficiency.The detection rate of thyroid nodules is higher in female than in male and it has increased with age.

Objective To evaluate the anestheisa efficacy of periprostatic nerve block in transrectal ultrasound (TRUS) guided biopsy of the prostate.Methods A total of 223 patients received prostate biopsy in our hospital from July 2010 to December 2013 were retrospectively studied,and were divided randomly into two groups.One hundred and sixteen cases in nerve block group accepted local anesthesia of prostate capsule and periprostatic nerve block after local perineal skin anesthetia,and 107 cases in local anesthesia group only accepted local perineal skin anesthetia and local anesthesia of prostate capsule.Patients in the 2 groups underwent prostate biopsy successfully.The visual analogue scale (VAS) and complications were recorded.Results The age,serum PSA level before biopsy,prostate volume and the number of puncture needles had no significant differences between the 2 groups (P＞0.05).The average VAS score was 2.3± 1.1,and 4.9±2.3 in the 2 groups.The VAS had significant difference between the 2 groups (P＜0.05).The incidences of hematuria,hemospermia and urinary retention were 37.1％ (43/116),3.4％ (4/116) and 1.7％ (2/116) in nerve block group,and 39.3％ (42/107),4.7％ (5/107) and 1.9％ (2/107) in local anesthesia group.The difference was not significant (P＞0.05).Conclusion Periprostatic nerve block for TRUS guided biopsy of the prostate could be safe with good analgesic effect.

B7-H3 is an immune checkpoint molecule overexpressed on the surface of a variety of tumors, and is is an ideal target for tumor immunotherapy. In this study, nitrolated T cell epitope designed in the early stage of the laboratory was used to construct an epitope vaccine that can target immune checkpoint B7-H3. The vaccine can significantly inhibit tumor growth in the CT26 colon cancer model, and has a significant synergistic effect with the PD-L1 protein vaccine. B7-H3 vaccine can increase the proportion of CD4+ T cells in splenic T lymphocytes and the proportion of CD8+ T cells in tumor-infiltrating T lymphocytes, while reducing the proportion of suppressor Treg cells in tumor-infiltrating CD4+ T lymphocytes, which effectively improves tumor immunosuppressive microenvironment. Research results suggest that the B7-H3 epitope vaccine can be used as an effective tumor vaccine candidate molecule.

Objective To observe the clinical characteristics and treatment of cytomegalovirus retinitis (CMVR) in leukemia patients.Methods This is a retrospective analysis. Seven leukemia patients (13 eyes) with CMVR were studied. All patients underwent examinations of visual acuity, slit lamp microscope, ophthalmoscope, color fundus photography, peripheral blood CD4+T cell count and serum/aqueous CMV-DNA test. All patients were treated with ganciclovir or zoledronic acid combined with intravitreal injection of ganciclovir. The follow-up period was 3-14 months.Results Six patients were treated with hematopoietic stem cell transplantation and 1 patient was with chronic leukemia. All patients were CMV-DNA positive for serum, and 18.5％ (2/7) for aqueous humor. CMVR in leukemia patients showed mild anterior segment inflammation, ocular fundus with irregular yellowish-white retinal necrosis and radial hemorrhage (7 eyes). Some (2 eyes) also shoed gray and white granular retinal infiltrates. Intravenous ganciclovir/zoledronic acid combined with intravitreal injection of high concentration ganciclovir was an effective treatment, while systemic corticosteroids were effective in reducing vitreous opacity.Conclusions CMVR is characterized by progressive necrotic retinitis with hemorrhage and vasculitis. Intravenous ganciclovir/zoledronic acid combined with intravitreal injection of ganciclovir is effective in the treatment of CMVR with leukemia.

Objective To explore the prevalence and analyze the related risk factors for post-stroke depression among middle-aged and elderly stroke patients of Mongolia and Han nationality in Inner Mongolia Autonomous Region.Methods A stratified multistage random cluster sampling method was used to investigate the prevalence of stroke in the population aged ≥45 years in different areas of Inner Mongolia Autonomous Region.A total of 11 088 people were investigated and 498 were stroke patients among them.A set of scale assessment and the general situation were used to investigate stroke patients and 443 patients completed the whole survey.Results The total prevalence of post-stroke depression (PSD) was 41.08％ in 443 stroke patients,among which the prevalence rate was 40.57％ for Mongolian population and 41.85％ for Han population,and no significant difference was found between Mongolian and Han nationality(x2=1.372,P=0.504).There were significant differences in the types of stroke between the Mongolian and Han nationality (x2 =7.347,P=0.025).The age (t=4.321,P=0.000),educational level (x2 =27.036,P=0.001) and economic burden (x2=27.877,P=0.000) were statistically significant between Mongolian and Han nationality.The differences of frequency of stroke (x2 =6.545,P=0.011),economic burden (x2 =16.148,P=0.001),cognitive dysfunction (x2 =9.065,P=0.003),daily living ability (x2 =34.466,P =0.000),alcohol consumption history(x2=4.516,P=0.034)were statistically significant.Logistic regression analysis showed that alcohol consumption history,economic burden,the frequency of stroke,and cognitive dysfunction were the influencing factors of PSD.Conclusion PSD is one of the important factors affecting the post-stroke psychological burden in Inner Mongolia Autonomous Region.There is no national difference in the prevalence of PSD among Mongolian and Han people,which provides a theoretical basis for the treatment and intervention of PSD.

Using the genetic code extension technology, the immunogenic amino acid, p-nitrophenylalanine, was introduced into the universal T cell epitope and then fused with the fragment of the extracellular region of the immune checkpoint molecular CD47(19-140)to construct a vaccine targeting CD47. The CD47-NitraTh vaccine elicited high titer antibody in BALB/c mice, significantly inhibited CT26 colon cancer cells growth, and increased the ratio of spleen CD4+ T cells and CD8+ T cells. Meanwhile, it promoted the polarization of naï ve T cells to Th1 cells. Notably, CD47-NitraTh not only increased the proportion of tumour-infiltrating lymphocytes but also reduced the proportion of Treg cells in tumour tissues, which means that CD47-NitraTh vaccine can remodel the tumour immunosuppressive microenvironment. The results of this study suggested that CD47-NitraTh can be used as an effective tumour vaccine candidate.
