Objective To evaluate the comprehensive treatment results of cystitis glandularis. Methods A total of 65 cases of cystitis glandularis underwent cystoscopy.The results showed follicular or villous changes in 39 cases,papillomatous in 15,chronic inflammation in 8 and no obvious change in 3.Transurethral electric resection or partial cystectomy were performed.After surgery all the cases received mitomycin-c bladder irrigation at high dose (40 mg once) regularly for 2 years.During the follow-up cystoscopy was periodically performed and the biopsy samples were pathologically examined with all the cases. Results The mean follow-up was 29 months (range,7 to 72 months).Of the 65 cases,60 fully recovered with transitional cell surface covering the bladder musoca gradually;4 had relapse;and 1 developed canceration (adenocarcinoma). Conclusions Transurethral resection of bladder tumors or galvanocautery is the essential therapy for cystitis glandularis.After surgery the bladder irrigation with mitomycin-c at high dose can be helpful for urothelium recover in histology.

Objective To probe into the diagnosis and treatment of pheochromocytoma of high risk. Methods The clinical data of 35 cases of pheochromocytoma of high risk underwent surgical extirpation from 1990 to 2000 were reviewed. Results The tumors were intraadrenal in 27 and extraadrenal in 8.The average diameter of the growth which could be successfully resected was 10 cm and the weight 350 g.Biopsy was undertaken in 2 because of the difficulty in extirpation of the tumor.Recurrence occurred in 4 and there were 3 cases being comfirmed to be malignant. Conclusions Adequate preoperative preparation and definite location of the tumor are the most important before surgery.Fluctuation of blood pressure have to be monitored during surgery and to be treated carefully and promptly.Hypoglycemia have to be awared of after the surgery.

Objective To improve the diagnosis and treatment ot adrenocorticotropin-independent macornodular adrenal hyperplasia (AIMAH).Methods The clinical data of 17 cases with AIMAH from 2000 to 2011 were analyzed retrospectively,including 3 subclinical AIMAH,10 clinical AIMAH and 4 highrisk AIMAH patient,with common radiological characteristic of bilaterally enlarged adrenal glands with multiple nodules like ginger.The 3 cases of subclinical AIMAH patients presented with decreased serum ACTH,normal or slightly elevated plasma cortisol and urinary free cortisol level,no suppression following 1 mg overnight dexamethasone suppression test and absence of clinical signs of Cushing syndrome (CS).While clinical AIMAH and high-risk AIMAH presented with clinical signs of CS,elevated plasma cortisol and urinary free cortisol level,suppressed serum ACTH,loss of normal circadian rhythm in cortisol secretion and no suppression following the low-dose and high-dose overnight dexamethasone suppression test.Among the 4 cases of high-risk AIMAH,2 cases presented with osteoporosis,2 cases with hepatic dysfunction,3 cases with cardiopulmonary dysfunction,and 4 cases with severe hypertension.Three cases of subclinical AIMAH were treated with symptomatic treatment,10 cases of clinical AIMAH patients with surgical operation,4 cases of high-risk AIMAH patients with ketoconazole and surgical operation.Results Three subclinical AIMAH patients received symptomatic treatment and discharged from hospital with normal blood pressure and blood glucose.During the period of follow-up from 3 months to 3 years,endocrine results were normal.Seven clinical AIM AH patients underwent unilateral adrenal tumor resection plus ipsilateral partial adrenalectomy or total adrenalectomy.CS disappeared completely after 6 to 9 months.Two clinical AIMAH patients underwent simultaneous bilateral adrenalectomy.One case died of adrenal crisis after operation,and the other case presented with adrenal insufficiency but returned to normal after glucocorticoid replacement therapy,no Nelson's syndrome happened during the follow-up for 5 years.One clinical AIMAH patient undertook unilateral adrenalectomy twice by interval,followed by routine corticosteroid replacement therapy.Followed up for 10 years,no Nelson's syndrome happened.Four high-risk AIMAH patients received ketoconazole and then underwent right total adrenalectomy.Cortisol levels returned to normal after 1 to 2 months and during the follow-up for 1 to 3 years,the laboratory examinations maintained normal.Conclusions Different treatment methods should be adapted to different subtypes of AIMAH.For subclinical AIMAH,the principal treatment is symptomatic,and close follow-up with regular adrenal imaging and endocrine examination is required.Surgical operation should be performed when clinical symptoms of AIMAH appear.Medical management is essential for high-risk AIMAH to inhibit the production of cortisol at first.Once these patients could stand the stimulation caused by operation,the adrenal glands should be resected as soon as possible.The unilateral adrenalectomy is an effective treatment for clinical AIMAH.

be diagnosed by imaging examination before operation.The ALT patients with large or symptomatic adrenal lipomatous lesions or preoperatively diagnosed teratoma should be given surgical treatment.

Objective To investigate the clinical characteristics of pulmonary hypertension(PH) in patients with chronic obstructive pulmonary disease (COPD) and study the related risk factors.Methods Patients with stable COPD enrolled in this study,undergoing examinations including full pulmonary function tests (PFT),6-minute walk distance (6MWD),Exercise Oxyhemoglobin,Saint.George's respiratory questionnaire (SGRQ) and transthoracic echocardiography.Pulmonary artery systolic pressure (sPAP) ≥ 36 mmHg(1 mmHg =0.133 kPa) was defined as PH.Results A total of 251 patients were finally evaluable in this study.The frequency of PH was 55.4％ (139/251) in patients with stable COPD.Significant differences were seen between patients with PH and without PH respectively in the following factors (mean P ＜0.05):proportion of age ≥ 60 years (69.8％ vs 57.1％),forced expiratory volume in one second (FEV1)(％ predicted) [(47.5±8.2)％ vs(61.2±10.2)％ and(49.8±7.9)％ vs(66.4±11.3)％],sPAP [(41.9 ± 9.1) mmHg vs (28.2 ± 3.2) mmHg],exercise oxyhemoglobin desaturation [(-5.5 ± 3.2) ％ vs(-2.2 ± 1.2) ％],6MWD [(316.0 ± 55.2) m vs(390.0 ±75.2) m].The following variables were negatively correlated with sPAP:6MWD (r =-0.330,P =0.003),FEV1 (％ predicted) (r =-0.210,P =0.024 and r =-0.130,P =0.012,respectively).The following variables were positively correlated with sPAP:age(r =0.560,P =0.031),exercise oxyhemoglobin desaturation ＞ 3％ (r =0.540,P =0.001).Logistic regression test has showed that age≥ 60 years,exercise oxygen desaturation ＞ 3％,FEV1 (％ predicted) ＜ 50％,6MWD ＜ 350 m were risk factors for PH in COPD.Conclusion The incidence of PH in COPD increases with age,yet the performance of lung function and the activity of endurance decrease in elder patients.Sixty years or older,exercise oxygen desaturation ＞ 3％,FEV1 (％ predicted) ＜ 50％,6MWD ＜ 350 m are risk factors of PH in COPD.Echocardiography or right heart catheterization when needed should be considered to confirm the diagnosis.

Objective To review the experience with partial cystectomy combined with chemo-and radiation therapies in the treatment of muscle-invasive bladder cancer (MIBC) to assess the local control and survival rates,and to identify predictive factors for recurrence and survival.Methods From 2002 through 2007,a total of 100 patients with MIBC underwent partial cystectomy combined with adjuvant chemotherapy and radiation therapy (PC group).Meanwhile,36 patients with MIBC underwent radical cystectomy (RC group).The clinical and pathological data of these patients were retrospectively reviewed.Primary endpoints were cancer-specific survival (CSS),bladder-intact cancer-specific survival and bladder cancer recurrence.Results The 5-year CSS rate of the entire cohort was 65％,which was higher in PC group than in RC group (68％ vs 55％,P =0.033).In PC group,only 2 patients (2％) were confirmed to have residual tumor at the time of re-evaluation TUR 3 months after partial cystectomy.After a mean of 33.1 months,46 patients (46％) experienced superficial recurrence and 14 patients (14％) developed muscle-invasive recurrence.75％ of recurrence occurred within 16 months.8 patients underwent salvage cystectomy.The 5-year bladder-intact survival rate was 63％ in PC group.In multivariate analysis,the presence of tumor numbers more than 3 and tumors with infiltrating growth pattern were 2 predictive factors for cancer recurrence in PC group.In terms of survival,the presence of tumor numbers more than 3,lymphovascular invasion and partial cystectomy plus ureteral reimplantation (PC plus UR) were significantly associated with 5-y CSS in PC group and PC plus UR was indeed a protective factor for survival.By looking at the entire MIBC cohort,lymphovascular invasion,tumor numbers more than 3,history of superficial bladder cancer and age greater than 70 years old were identified as independent predictive factors for 5-y CSS.Conclusions Combined with adjuvant chemo-and radiation therapies,partial cystectomy might be a alternative to radical cystectomy for the treatment of MIBC,which provides adequate local control in selected patients,as well as acceptable survival rate.

Objective To investigate the diagnosis and treatment of extra-adrenal pheochromocytoma(EAP). Methods The clinicsl data of 37 cases of EAP from April 2003 to April 2010 were retrospectively analyzed.Hypertension was observed in 31 cases.The typical triad of headache,palpitation and sweating was observed in 12 cases.The positive rate of plasma-free MNs and 24-hour urinary CA in diagnosing EAP was 96.8%(30/31) and 86.5% (32/37) respectively.The main localization diagnosis included ultrasonography,CT,MRI and 131I-MIBG,with positive rates of 91.7% (33/36),97.0%(32/33),90%(9/10) and 82.6%(19/23) respectively.Two patients underwent radiotherapy, and the remaining 35 cases underwent surgical treatment. Results Among the total of 37 cases,32 cases were single tumor,and five were multiple tumors.The anatomic locations of the single tumors were as follows: 14 wre adjacent to the abdominal aorta,seven in the bladder,four adjacent to the inferior vena cava,four adjacent to the renal hilum,two adjacent to the lilac blood vessel and one in the upper pole of the right kidney.Thirty cases underwent complete tumor resection,three cases underwent tumor resection plus right nephrectomy and two cases underwent partial cystectomy.Twenty-four cases were diagnosed benign and 11 cases were diagnosed malignant by pathological examination.Among 31 cases with preoperative hypertension,postoperative blood pressure returned to normal in 23 patients,blood pressure descended mildly in six cases and blood pressure was still hypertensive in two cases.Thirty-four patients were followed up for five months to seven years,during which five cases had tumor recurrence or metastases and five cases died postoperatively. Conclusions EAP is a rare neuroendocrine tumor and its accurate diagnosis is rather difficult.Plasma-free MNs and 24-hour urinary CA are important qualitative examinations.Ultrasonography,CT,MRI and 131I-MIBG scintigraphy are important methods for the localization of the tumor.Transperitoneal resection of the tumor is the preferred choice of management and adequate perioperative preparation is the key to a successful operation,including bringing down blood pressure,expanding blood volume and correcting arrhythmia.Patients with malignant EAP may be treated with 131I-MIBG after surgical therapy.

Fear memories are temporarily suppressed after repeated retrieval, a phenomenon known as memory extinction.How to reduce or even eliminate fear memory is the key to the treatment of fear related diseases such as post-traumatic stress disorder(PTSD). A single extinction training based on Pavlov's fear regulation task could only inhibit the expression of conditioned fear memory traces, but it could not eliminate the acquired conditioned fear memory. However, according to the reconsolidation theory based on memory, the retrieval-extinction paradigm has a more lasting effect on the erasure and rewriting of fear memory, and can effectively prevent the return of fear memory. Studies have shown that extraction-regression is closely related to a variety of neurotransmitter receptors such as glutamate receptor(GluR), dopamine receptor(DAR), L-type voltage-gated calcium channels(LVGCs) and cannabinoid. Moreover, its effect is closely related with factors such as retrieval-extinction memory stage. At present, most of the researches on extracted boundary conditions only stay at the level of behavior, with little understanding and exploration on the level of molecular mechanism. From the perspective of molecular neurobiology, with different stages of memory and different types of receptors and molecular mechanisms, this research reviewed the mechanisms of retrieval-extinction in recent years.It provided valuable signaling pathways, molecular targets and research directions for the treatment of fear-related diseases such as PTSD.

Objective: To monitor and analyze the epidemiological characteristics of influenza in schools and understand the disease burden of students, and to provide a scientific reference for instructing the prevention of influenza in schools. Methods: A school influenza surveillance sentinel to conduct influenza like case (ILI) surveillance and outbreak surveillance. Through network, we understood the burden of flu disease among students. Descriptive epidemiology was used to analyze influenza like case surveillance and questionnaire survey data. Results: Surveillance confirmed that from the 42th week of 2019 to the 1st week of 2020, the cumulative reported ILI of 3 school influenza surveillance sites in Jinan accounted for 7.91% (ILI%) of the total number of surveillance personnel during the same period, with the highest ILI% (24.19%) of kindergarten children, ILI% gradually decreased with the increase of grade, and teachers were the lowest. The reporting of ILI was concentrated in the 49th to 52nd week of 2019, during which the reported influenza like cases accounted for 84.81% of the total number of ILI reported during the surveillance period. Two influenza outbreaks were monitored. The pathogens were H3N2 and B (Victoria). The epidemics mainly occurred in the lower grades of elementary school. A survey of 2 297 students found that 577 people had fever and respiratory symptoms since October 2019. Among them, 85.26% of them went to the hospital, 32.75% of those who used anti influenza drugs such as oseltamivir, and 64.81% of those who used antibiotics. 42.63% received infusion therapy, 3.99% were hospitalized, and the average cost of inpatients was 6 686 yuan. The sick students were absent from school for an average of 3.77 days, and the parents of the sick children missed work for an average of 4.26 days. Conclusion Surveillance of influenza like cases in schools is an important way to proactively discover influenza epidemic trends and outbreaks, and to accurately grasp the characteristics of influenza epidemics in schools. The key populations affected by influenza are kindergarten children and lower grades of primary school students. Suffering from influenza has caused a heavy disease burden on students and children in kindergartens, and is also an important factor that causes student absenteeism and parents to miss work.

Objective: To evaluate the new compensation mechanism for primary healthcare institutions in Zhejiang province, in terms of fairness, performance, incentive mechanism and sustainability in pilot areas. Methods: Evaluation indicators were constructed based on stakeholder theory, fairness theory, expectation theory and sustainable development theory.Focus group interviews were conducted with stakeholders and quantitative data were collected through questionnaires. Meanwhile, the financial compensation, income and expenditure and work equivalent data were collected from such institutions of the four pilot areas, with quantitative data subject to descriptive analysis. Results: This study found the reform used reasonable proportion of funds allocated(the proportion of basic salary for employees was lower than 50%)and adjustment factors(1.0-1.8)of different primary healthcare institutions to guarantee the fairness of the reform; the increase of work equivalents(the per capita work equivalents of medical staff in pilot counties had increased from 38.435 million in the previous year to 42.590 million work equivalents)reflected the performance outcomes of the reform. The incentive and sustainability of the reforms were the weak parts. These were mainly due to the fact that the internal distribution system of primary healthcare institutions failed to make corresponding reforms. Conclusions The reform of the compensation mechanism based on the equivalent method has changed medical staff′s perception of the distribution of funds. The principle of" more pay for more work" and the use of information technology to capture work equivalents have improved the enthusiasm of primary medical staff and the operational efficiency of these institutions, thus, making reform generally scientific and reasonable.
