Objective: To explore the effect of previous treatment on the efficacy of multidrug resistant pulmonary tuberculosis (MDR-TB) patients. Methods: From February 2015 to February 2017, 64 cases with MDR-TB who received treatment in the First Hospital of Ninghai were collected.All patients received antituberculous therapy for 6 months.The clinical data were retrospectively analyzed.The factors that influence the efficacy of MDR-TB patients were evaluated by multivariate logistic regression analysis. Results: After standard chemotherapy for MDR-TB patients, the incidence of chest radiographic lesions in primary and relapsed MDR-TB patients was 18 cases(81.82%) and 21 cases(50.00%), respectively.There was statistically significant difference between the two groups (χ²=22.835, P<0.05). The cavity closure rate of MDR-TB patients after primary treatment and relapse was 54.55% and 40.48%, respectively, and there was significant difference between the two groups (χ²=8.693, P<0.05). After standard chemotherapy for MDR-TB patients, the cure rates of primary and recurrent MDR-TB patients were 18 cases(81.82%) and 23 cases (54.76% ), respectively, there was statistically significant difference between the two groups (χ²=21.791, P<0.05). Conclusion The effect of initial treatment of MDR-TB is better than recurrent MDR-TB, so it is necessary to strengthen the surveillance of drug resistance in patients with tuberculosis and to find the disease as soon as possible.Early treatment of MDR-TB is the best option for patients.

ObjectiveTo characterize the incidence of laboratory confirmed pertussis cases by immunization status in Ninghai County， and to provide evidence for improving pertussis prevention and control strategy in Ninghai County. MethodsData of reported pertussis cases in Ninghai County from 2018 to 2019 were collected through the National Notifiable Infectious Disease Reporting System. The immunization history of vaccines related to pertussis was collected through the Ningbo Immunization Planning Information Management System and field investigation. Descriptive epidemiological methods were used to analyze the collected data. ResultsThe respiratory secretions collected in the 64 cases tested positive for nucleic acid of Bordetella pertussis bacilli， of which 56.25% aged 0‒1 year. They were mainly pre-school children. No adolescent or adult case was reported. All cases had whooping cough. Of the cases， 78.13% had an increase in white blood cell count， 62.5% had an increase in lymphocyte percentage， 59.38% had completed three or more doses of pertussis vaccination， 69.39% had a time interval of >1 year between the onset and last dose of pertussis vaccination， and 31.25% reported close contact with pertussis patients before the onset. The misdiagnosis rate of pertussis was as high as 92.19%. In contrast， the prevalence of anti-pertussis IgG antibody in health population was 1.05%. ConclusionFurther improvement in the laboratory testing capacity can help clarify the diagnosis of pertussis. Generally， children aged 0-1 year are mainly affected， of which vast majority have received at least one dose of pertussis vaccination. Clinical symptoms are characterized by whooping cough. Additionally， elevated white blood cells and lymphocytes should be on the alert to pertussis infection.

Background Pneumoconiosis is one of the most common and widespread prescribed occupational diseases in China, and there is no cure for it at present. The Healthy China 2030 underlines that the prevention and treatment of pneumoconiosis are the critical element of promoting occupational health. Objective To understand the basic characteristics, social security, and death causes of pneumoconiosis cases in Ninghai County, and to provide a basis for scientific prevention and treatment of pneumoconiosis. Methods Information on pneumoconiosis cases in Ninghai County from 1974 to 2019 was obtained by consulting occupational disease and occupational health information monitoring systems, occupational disease diagnosis institutions, and employers, which may retain original data on occupational pneumoconiosis diagnosis, as well as specialized epidemiological survey projects on pneumoconiosis. Telephone or face-to-face follow-up visits were conducted based on relevant information to complete or verify relevant information such as length of service with dust exposure, type, stage, and diagnosis date of pneumoconiosis. ANOVA, chi-square test, and rank-sum test were used to analyze age of diagnosis and age of death, entitlement to social security and mortality rate of cases/length of service. Results As of the end of 2019, a total of 420 cases of pneumoconiosis were diagnosed among workers exposed to dust in Ninghai County, with 409 cases (97.38%) followed up and 11 cases (2.62%) lost to follow-up. Since the first case of pneumoconiosis was reported in 1974, 39 cases, 278 cases, and 101 cases of pneumoconiosis were reported before 2000, from 2000 to 2009, and from 2010 to 2019, respectively. Two other cases of pneumoconiosis were diagnosed with an unknown year, one as a dead case and one as a lost case. There were 294 surviving pneumoconiosis cases, who mainly lived in Sangzhou Town. The mean age of diagnosis was (58.68±15.37) years old, and the median length of service with exposure to dust was 8.0 (4.0, 15.7) years. The age of diagnosing stage III pneumoconiosis was less than that of stage I and stage II, and the difference between the age of diagnosing stage III and stage II pneumoconiosis was significant (P <0.05). There were 231 cases (78.57%) aged ≥ 60 years, while there were 74 cases aged ≥ 80 years (25.17%). There were 160 cases (54.42%) whose length of service was < 10 years. There were 12.59% and 7.82% of the total cases compensated by work injury insurance and civil compensation by employers, respectively. From the perspective of diagnosis period, the proportion of patients who collected work-related injury insurance and civil compensation from employers in the 2010—2019 year group was higher than that in the <2000 year group or the 2000—2009 year group (P<0.01). There were 115 fatal pneumoconiosis cases, and the fatality rates of stage I, II , and III pneumoconiosis were 23.86%, 18.18%, and 50.75%, respectively. The fatality rate of stage III pneumoconiosis was higher than that of stage I or II (P <0.05). The age of diagnosis and age of death of stage III pneumoconiosis cases were lower than those of stage I and II (P <0.05). The cause of death was definite in 65 patients, including 25 cases (38.46%) of respiratory diseases (except lung cancer) and 28 cases (43.07%) of tumors, and lung cancer accounted for 1/2 of the pneumoconiosis cases that died due to tumors. Conclusion The surviving pneumoconiosis cases in Ninghai are mainly older than 60 years old and largely live in Sangzhou Town. Constructing local rehabilitation stations should be taken as an opportunity to actively prevent and treat pneumoconiosis complications, further improving the quality of life of pneumoconiosis patients.

OBJECTIVETo analyze the differentially expressed genes in the testicular tissues of men with unilateral cryptorchidism using cDNA gene chips.

METHODSProbes were prepared with the mRNA extracted from the testes of 6 patients with unilateral cryptorchidism and 3 normal fertile men. Then the differential gene expression profiles of the two groups were detected with cDNA gene chips containing 45 034 genes. The differentially expressed genes were analyzed with Pathway and GO in the MAS system.

RESULTSBased on the ratio of > 3.0 or < 0.33, 346 differentially expressed genes were detected in the testis tissues of the patients with unilateral cryptorchidism, among which 60 were up-regulated and 286 down-regulated. The up-regulated genes were distributed mainly on chromosomes 1, 15, 5 and 19, associated with cell cycles, sperm motility, flagellar movement, DNA replication, and chromatin modification, while the down-regulated genes, mainly on chromosomes 1, 19, 16 and 11, related with spermatogenesis and anti-apoptosis.

CONCLUSIONUnilateral cryptorchidism involves the variation of the expressions of multifunctional genes. The establishment of gene expression profiles of unilateral cryptorchidism in human testes may provide a new theoretical basis for analyzing the genetic factors of unilateral cryptorchidism and investigating the etiology of spermatogenic failure.

ObjectiveTo understand the survival time and possible influencing factors of pneumoconiosis patients in Ninghai County， Zhejiang Province who were followed up from 2019 to 2023， and to provide references for prolonging the survival time of pneumoconiosis patients. MethodsInformation about pneumoconiosis patients was collected from the sub-module Occupational Disease Follow-Up Management and Follow-Up Excel database of the Occupational Disease and Health Hazards Monitoring Information System. Survival analysis was conducted through applying Kaplan-Meier survival curves and Cox regression models. ResultsOf the 366 pneumoconiosis patients， 99.73% were male， 71.04% had stage Ⅰ pneumoconiosis， and the disease type was mainly silicosis. The survival rates at 5， 10， and 20 years after diagnosis of pneumoconiosis were 97%， 88%， and 62%， respectively， with a cumulative survival rate of 42%. The median survival time of patients with pneumoconiosis was 32.11 years. Log-rank test found statistically significant differences in the survival curves among pneumoconiosis patients with different pneumoconiosis stages， age at first diagnosis， and pneumoconiosis complications. Cox regression analysis revealed that the risk of reduced survival time in patients with pneumoconiosis stage Ⅲ was 2.184 times higher than that of patients with stage Ⅰ （P=0.007）. In comparison with the age of first diagnosis at <50 years old group， the risk of reduced survival time was 3.457 and 7.097 times higher， respectively， in the groups of patients who received the diagnosis at 50‒ and ≥60 years （both P<0.001）. The risk of reduced survival time in pneumoconiosis patients with complications was 2.030 times higher than that of patients without complications （P=0.003）. ConclusionSurvival time of pneumoconiosis patients in Ninghai County is affected by the age at first diagnosis， pneumoconiosis stage and pneumoconiosis complications. The survival time can be significantly prolonged by timely detection and diagnosis， as well as active prevention and treatment of pneumoconiosis complications.

Objective: To investigate the clinical and pathological features, diagnosis and treatment of primary vulvar Paget disease (VPD) , and analyze the related factors that may affect the recurrence. Methods: A retrospective study was carried out on 36 patients diagnosed as VPD pathologically from January 1983 to December 2017 at Peking Union Medical College Hospital, Chinese Academy of Medical Sciences. The clinical and pathological features, diagnosis, treatment and prognosis and the factors influencing recurrence rate of VPD were analyzed. Results: (1) Totally 94% (34/36) of VPD occurred in postmenopausal women. Pruritus was counted 86% (31/36) of the main complaint. Lesions of vulvar were main symptom which had no specificity, acting as ulcer (67%, 24/36) , erythema (50%, 18/36) , depigmentation (42%, 15/36) , sclerosis (31%, 11/36) , and pigmentation (17%, 6/36) . The lesions invaded labium majus (97%, 35/36) , sometimes labium minus (53%, 19/36) , clitoris (28%, 10/36) , perianal (25%, 9/36) , orificium vaginae (3%, 1/36) , and meatus urinarius (3%, 1/36) . Approximately 19% (7/36) of VPD coexisted with intraepithelial neoplasia or adenocarcinoma of vulvar or other part of body. (2) Diagnosis and treatment: diagnosis was confirmed histologically by biopsy or pathologies after surgery, and immunohistochemical results were helpful for differential diagnosis. Surgery was the mean treatment method, 34 of all the 36 patients (94%, 34/36) underwent surgery for at least once, while 2 patients (6%, 2/36) were performed non-operative treatment. The surgical treatment included excision of focus, wide local excision, simple vulvectomy, and extensive vulvectomy. The non-operative treatment included radiotherapy, chemotherapy, laser, photodynamic therapy, and so on. (3) Prognosis: among 36 VPD patients, 4 were lost to follow-up with a 89% (32/36) follow-up rate. Median follow-up was 35.3 months (range,1 month to 31 years) . During the follow-up period, 2 patients were unable to judge whether they will relapse for the follow-up time did not reach half a year, 8 cases were unsuccessful operation, 20 cases succeeded, the achievement ratio was 71% (20/28) . Nine of twenty cases relapsed, the recurrence rate was 45% (9/20) . The median recurrence time was 14 months after operation. One patient of the 32 followed-up patients died, the mortality rate was 3% (1/32) . (4) The related factors affected the recurrence of VPD: t test was applied to the analysis of patients′ age, rank test was used in the statistics of the time of confirmed diagnosis, the length and thickness of the resection focus. Fisher test was used to calculate whether the focus were limited to the epidermis, type of surgical procedures, distance between the margin and the focus, whether tumor cells infiltrated the margin. The results showed that none of the above terms in the first operation had significant contribution to recurrence (all P>0.05) . Conclusions VPD may be a low potential malignancy, which could slowly progress into deep invasive disease. VPD is often associated with intraepithelial neoplasia or primary tumors of the vulva or somewhere else. Operations is the first choice for VPD, but consider for its high recurrence rate after operation, close follow-up should be strongly suggested.

OBJECTIVE: This study aims to evaluate the effects and pregnancy outcomes of gonadotropin-releasing hormone agonist (GnRH agonist) combined with aromatase inhibitor (AI) in preserving the fertility of obese women with grade 1 endometrial cancer (EC). METHODS: This study recruited obese EC patients who wished to preserve their fertility. The treatment regimen consisted of intramuscular GnRH agonist 3.75 mg every 4 weeks and oral AI 2.5 mg daily. The maintenance regimen was the same as the initial treatment regimen. Primary outcomes included response rate, time to complete response (CR), and time to recurrence; pregnancy outcomes included the time to pregnancy, pregnancy rate and live birth rate. RESULTS: Six obese patients with EC were included in this study, with the age (mean±standard deviation [SD]) of 30.5±3.3 years and body mass index (mean±SD) of 35.0±1.4 kg/m2. CR rate was 100%, and time to CR was 3–6 months. None of the patients had recurrence after a median follow-up of 4.0 years (range, 1.3–7.0 years). The most common side effects were menopause-like symptoms. Among these patients, no weight gain was observed during treatment. The pregnancy rate and live birth rate was 50.0% and 75.0%, respectively, with a median time to pregnancy of 2.4 years (range, 1.0–5.5 years). CONCLUSION: The combination of GnRH agonist and AI demonstrated promising long-term effect in young obese EC patients who wished to preserve their fertility. No weight gain side effects were observed. Further studies with a larger sample size are needed to fully evaluate this novel treatment regimen.

AIM: To explore the effects of preoperative application of dezocine patient-controlled analgesia pump on stress response and cognitive function in elderly patients with lower extremity fractures. METHODS: A total of 80 elderly patients with lower extremity fractures who were treated from November 2018 to June 2020 were selected and randomly divided into a control group and a study group, 40 cases in each. The control group was not given a patient-controlled analgesia pump before anesthesia, and the study group was given intravenous analgesia with a dezocine patient-controlled analgesia pump before surgery. The postoperative stress response, cognitive function and safety were compared between the two groups.RESULTS: There were no significant differences in cognitive function MMSE score, stress response index (cortisol, epinephrine) levels, and inflammatory factors (IL-6, TNF-α) levels between the two groups before intervention (P>0.05). Compared with the indexes after operation, the MMSE scores of the study group at 12 h, 24 h and 3 days after operation were higher than those in the control group (P<0.05); The levels of cortisol, epinephrine, IL-6 and TNF-α in the study group were lower than those in the control group at 12 h and 24 h after operation (P<0.05); At the same time, the incidences of respiratory depression, urinary retention and nausea and vomiting in the study group were significantly lower than those in the control group (P<0.05).CONCLUSION: Preoperative application of dezocine patient-controlled analgesia pump in elderly patients with lower extremity fracture can significantly reduce postoperative stress response, reduce inflammatory response, and improve postoperative cognitive function, which is worthy of clinical application.

Objective:To analyze the clinical efficacy and pregnancy outcomes of gonadotropin-releasing hormone agonist (GnRH-a) based fertility-sparing re-treatment in women with endometrial carcinoma (EC) and atypical endometrial hyperplasia (AEH) who failed with oral progestin therapy.Methods:Forty cases with EC or AEH who failed to respond to oral progestin were included from January 2012 to December 2020 at Peking Union Medical College Hospital. Combination of GnRH-a with levonorgestrel-releasing intrauterine system (group GLI: a subcutaneous injection of GnRH-a every 4 weeks and LNG-IUS insertion constantly) or the combination of GnRH-a with aromatase inhibitor (group GAI: a subcutaneous injection of GnRH-a every 4 weeks and oral letrozole 2.5 mg, daily) were used for these patients. Histological evaluation were performed at the end of each course (every 3-4 months) by hysteroscopy and curettage. After the complete remission (CR), all patients were followed up regularly.Results:(1) Clinical characteristics:among the 40 patients with EC or AEH, the median age at diagnosis was 31 years (range: 22-40 years) and the median body mass index was 24.7 kg/m 2 (range: 18.9-39.5 kg/m 2). (2) Efficacy of fertility-sparing re-treatment: 37 (92%, 37/40) patients achieved CR, 6 (6/7) in AEH and 31 (94%, 31/33) in EC patients. The CR rate was 93% (26/28) and 11/12 in group GLI and GAI, respectively. The median time to CR was 5 months (range: 3-12 months). At the end of the first therapy course, the CR rates in AEH and EC were 5/7 and 42% (14/33), at the second course, the CR rates were 6/7 and 82% (27/33), respectively. (3) Recurrence: after 25 months of median follow-up duration (range: 10-75 months), 8 (22%, 8/37) women developed recurrence, 1/6 in AEH and 7 (23%, 7/31) in EC patients, with the median recurrence time of 18 months (range: 9-26 months). Among them, two cases who had completed childbirth chose to receive hysterectomy directly. Six patients met the criteria of fertility-preserving therapy and received conservative treatment again and 5 (5/6) of them achieved CR. (4) Pregnancy: of the 37 patients with CR, 33 desired to conceive. Ten women attempted to get pregnancy spontaneously and 23 cases with assisted reproductive technology. Fourteen (42%, 14/33) patients became pregnant, including 9 (27%, 9/33) live births, 3 (9%, 3/33) missed abortions, and 2 (6%, 2/33) miscarriages at the second trimester. Conclusions:GnRH-a based fertility-sparing re-treatment in AEH or EC patients who failed with oral progestin therapy achieved good treatment effect and reproductive outcomes. It is an encouraging alternative regime for patients who failed with oral progestin therapy.
