Objective: To investigate the relationship between P27，P53 and PCNA expression in human gastric carcinoma tissues and clinicopathological parameters. Methods: The expression of P27，P53 and PCNA in 62 human gastric carcinoma tissues was examined with immunohistochemistry SP method. Results: Positive rates of P27，P53 and PCNA expression were 37.1％, 40.4%，83.9％. P27 expression was related with Bormann type, infiltrative depth, lymph node and distant metastasis and clinical stage. P53 expression was related with sex of patients, distant metastasis and clinical stage. PCNA expression was related with age of patients and infiltrative depth of tumor. P27 positive expression group was higher than negative group as to 5-year survival. P27 expression was in reverse relation with PCNA expression. Conclusion: The expression of P27, P53 and PCNA may be regarded as an important marker in judging malignant degree of gastric carcinoma,distant metastasis and prognosis.

OBJECTIVETo investigate the efficacy of interferon-alpha (IFN-alpha) therapy for HBeAg-negative chronic hepatitis B.

METHODSSixty-five Chinese HBeAg-negative chronic hepatitis B patients were treated with 5 MU recombinant rIFN-alpha 1b subcutaneously thrice weekly for 5 to 24 months, followed by 12 months of treatment-free follow-up; one hundred and eighty-eight Chinese HBeAg-positive patients served as controls. For each patient, serum alanine transaminase (ALT) was measured biochemically and serum HBV DNA level was detected with fluorescent-quantitative PCR, HBeAg with enzymoimmunoassay every 1 to 3 months during therapy and during the follow-up period. HBeAg loss (only for HBeAg-positive cases), HBV DNA undetectable, and ALT normalization: the three together were considered a combined response.

RESULTSRates of combined response were similar in HBeAg-negative patients (58.5%, 38/65) or HBeAg-positive ones at the end of treatment (weighted chi square test, chi2 = 1.878, P<0.05), but were higher at the end of the follow-up period in the HBeAg-negative cases (75.4%, 49/65) (weighted chi square test, chi2 = 4.796, P<0.05). Furthermore, relapse rates at the end of the follow-up period, were also similar in HBeAg-negative patients (15.8%, 6/38) or HBeAg positive (chi2 = 0.205, P>0.05). Combined response was achieved at a median of 6.0 months (2-16 months) of treatment course in HBeAg-negative patients while at a median of 6.0 months (1-22 months) in HBeAg-positive cases (Z = -0.186, P>0.05, by the Wilcoxon rank sum test). The only factor predictive of combined response, by binary logistic regression analysis, was inflammatory activity in the liver biopsy. Gender, age, baseline ALT level, baseline HBV DNA level, and anti-HBe were not predictive factors.

CONCLUSIONInterferon-alpha therapy induces a similar primary and sustained response in HBeAg-negative and in HBeAg-positive chronic hepatitis B patients.

BACKGROUNDBladder urothelial cancer has been diagnosed at an increasing rate among young adults in China while the clinical outcomes remain highly controversial. To optimize the management of young patients with bladder cancer, we examined whether bladder urothelial cancer in young patients behaved differently from that in the elder patients.

METHODSFrom 1994 to 2008, a database of bladder urothelial cancer patients at a major tertiary medical center was retrospectively reviewed. The clinical and pathological parameters of patients who were less than 40 years of age and a series of patients older than 40 years of age as the control group during the same period were compared. A survival analysis was performed using the Kaplan-Meier method and log-rank test, and Cox regression was performed to identify clinical parameters that affected the clinic outcomes.

RESULTSYoung bladder cancer patients had a lower male-to-female ratio and were less likely to have advanced stages and high-grade cancers at the initial diagnosis. Tumors in young bladder cancer patients tended to be less multifocal at diagnosis. In addition, young patients had a lower recurrence rate and longer recurrence interval than older patients. The Kaplan-Meier curve and Log-rank test showed that young patients had significantly better cancer specific survival than old patients. The univariate and multivariate Cox regression analysis revealed that tumor grade is the sole predictor for tumor recurrence in young patients.

CONCLUSIONSYoung patients with bladder cancer have favorable pathological features and clinical outcomes than older patients. These findings argue for more conservative management approaches for young patients with bladder cancer.

OBJECTIVETo evaluate reimplantation of devitalized autogenous calvarial bone flaps and the fixation of titanium clamps (CranioFix) for cranioplasty.

METHODSFrom March 2000 to December 2003, 21 patients underwent (1) delayed reimplantation of preserved autogenous bone flaps, which were removed during the initial operations for increased intracranial pressure and stored in a freezer and autoclaved before use, or (2) immediate reimplantation of tumor invaded bone flaps that were devitalized by boiling. All of these flaps were fixed with titanium clamps (CranioFix). Resorption of the bone flaps was monitored by skull roentgenograms and computed tomography (CT). The clinical and aesthetic results were evaluated.

RESULTSDuring the follow-up period of 6 to 30 months, no complications were found. There was slight resorption of the bone flaps in all cases, but the edge of the bone flaps was within the range of the titanium clamps according to skull roentgenograms and CT. Clinical and aesthetic results were highly satisfactory.

CONCLUSIONSIt is simple and practical using devitalized autogenous calvarial bone flaps for cranioplasty. The firmness decreasing of the reimplanted bone flap due to resorption can be prevented greatly by titanium clamps (CranioFix).

OBJECTIVETo investigate the T lymphocyte subgroups and the levels of serum zinc (Zn), selenium (Se), iron (Fe), copper (Cu) in patients with diarrhea type of irritable bowel syndrome (D-IBS).

METHODSA total of 30 D-IBS patients and 30 control subjects were enrolled in this study, and their peripheral blood samples were collected. The percentage of peripheral CD3, CD4, CD8 T lymphocytes were analyzed by flow cytometry, and the ratio of CD4/CD8 was calculated. Serum Zn, Fe and Cu levels were determined by atomic absorption spectrometry(AAS), and the Se level by atomic fluorometry.

RESULTCompared with control group,the percentage of CD4 T lymphocyte and the ratio of CD4/CD8 in D-IBS group were significantly lower (P<0.01). However, there was no significant difference in serum Zn, Se, Fe, Cu levels between two groups (P>0.05).

CONCLUSIONThe declines of peripheral blood CD4 T lymphocytes and the ratio of CD4/CD8 may suggest a cellular immune abnormality in D-IBS patients. There was no significant difference in trace elements levels between the two groups.

OBJECTIVETo evaluate the community-based health promotion effect of physical activity.

METHODSThe residents aged 18 and above from two communities in Gongshu District of Hangzhou City, Zhejiang province, were randomly selected and recruited for the multi-strategy and comprehensive physical activity intervention. Questionnaire survey, physical check up and blood biochemistry were conducted.

RESULTSAfter this two-year intervention, the time of the participant spent on weekly physical activity of moderate intensity increased from 464 min to 542 min (P<0.05), with an average increase of 78 min. Time spent in walking every week increased from 533 min to 678 min (P<0.05), with an average increase of 145 min. The body weight, waistline, blood pressure and heart rate all reduced significantly (P<0.05); the vital capacity increased significantly (P<0.05); and the related biochemical indicators were also improved.

CONCLUSIONComprehensive and evidence-based physical activity interventions targeting community population can improve the levels of physical activity, related body measurement and biochemical indicators.

Objective To study the relevant factors on an measles outbreak caused by imported new virus (d11 genotype)from Myanmar and to develop effective strategies and measures.Methods On-site investigation on the outbreak was carried out. Results There were four townships (66%) in Menglian county reported 15 cases of measles, with 7 cases aged 6 months to 5 years old, 2 cases with the history of measles vaccination (MV). Another 8 cases were 21 to 49 year-olds but their histories on immunization were unclear. 14 of the measles cases with Myanmar citizenship came to China for treatment. They were aged 10 months to 13 years old, with only one case had ever received MV vaccination. For all the 29 cases, except for one case who did not adopt the sample case of Myanmar, the remaining 28 patients were positive for measles IgM antibodies. 6 cases of measles virus RNA were detected in the amplified sequence which showed genotype d11, and was considered Myanmar imported wild virus. 184 people received the MV inoculation, with a rate of 61.96% and the serum samples showed a measles IgG antibody positive rate of 87.50%. Manner MV emergency vaccination was carried out timely in that county so the measles outbreak was effectively controlled.Conclusion Imported measles cases from foreign countries might lead to epidemic, indicating the difficulty and challenge in the elimination of measles in our province. Emergent vaccination of MV could interrupt the transmission of the disease. Our experience showed that MV was effective in the prevention of d11 genotypes measles infection in the area.

AIMTo evaluate the efficacy of biofeedback therapy in patients with chronic pelvic pain syndrome (CPPS).

METHODSFrom November 2001 to April 2002, patients visiting the Urological Outpatient Clinic of this Hospital were evaluated by means of the National Institute of Health Chronic Prostatitis Symptom Index (NIH-CPSI) and classified by the NIH classification standard. Sixty-two patients of CPPS category III were involved in this study. All patients had been treated by conventional approaches such as antibiotics and alpha-blockers for more than half a year without any improvement. The expressed prostatic secretion results were as follows: WBC 5 to 9/high power field, lipid + approximately +++ and bacterial culture negative. Their NIH-CPSI were 12 approximately 40. All the 62 cases complained of micturitional irritation (frequency, urgency, splitted stream and sense of residual urine), 32 cases, of pain or discomfort at the testicular, penile, scrotal, pelvic or rectal region and 13 cases, of white secretion-dripping. The patients were treated by the Urostym Biofeedback equipment (Laborie Co., Canada) 5 times a week for 2 weeks with a stimulus intensity of 15 mA approximatley 23 mA and duration of 20 minutes.

RESULTSSixty patients were significantly improved or cured, while no significant improvement in the remaining 2. No apparent side effect was observed. The NIH-CPSI dropped to 6 to 14 with an average reduction of 21 (P<0.01). In the 60 improved cases, pain was relieved after 2 approximately 3 treatment courses and other symptoms disappeared after 4 approximately 5 courses.

CONCLUSIONBiofeedback therapy is a safe and effective treatment for CPPS. Large randomized clinical trials are needed to confirm its efficacy and to explore the mechanism of action.

Several studies have demonstrated an association between physical activity and telomere length; however, the association remains inconsistent. A cross-sectional study consisting of 588 participants (375 females, median age of 33.8 years) was carried out to investigate the association between telomere length and physical activity in a general population from North China. The results show that relative telomere length is not significantly different in participants in the northern Chinese population with different levels of physical activity, either in the model only adjusted for age (F = 2.127, P = 0.120) or in the model adjusted for demographics and lifestyle (F = 1.227, P = 0.294). The gender-stratified analysis also produced insignificant results. Our study confirmed a non-significant association between physical activity and telomere length in the northern Chinese population, which adds to the inconsistent association between physical activity and telomere length across different ethnic populations.

Objective: To evaluate the safety and efficacy of anlotinib plus irinotecan in the second-line treatment of patients with metastatic colorectal cancer (mCRC). Methods: This prospective phase 1/2 study was conducted in 2 centers in China (Cancer Hospital of Chinese Academy of Medical Sciences and Jiangsu Province Hospital). We enrolled patients with mCRC whose disease had progressed after first-line systemic therapy and had not previously treated with irinotecan to receive anlotinib plus irinotecan. In the phase 1 of the trial, patients received anlotinib (8 mg, 10 mg or 12 mg, po, 2 weeks on/1 week off) in combination with fixed-dose irinotecan (180 mg/m(2), iv, q2w) to define the maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D). In the phase 2, patients were treated with the RP2D of anlotinib and irinotecan. The primary endpoints were MTD and objective response rate (ORR). Results: From May 2018 to January 2020, a total of 31 patients with mCRC were enrolled. Anlotinib was well tolerated in combination with irinotecan with no MTD identified in the phase 1, and the RP2D was 12 mg. Thirty patients were evaluable for efficacy analysis. Eight patients achieved partial response, and 21 had stable disease, 1 had progressive disease. The ORR was 25.8% and the disease control rate was 93.5%. With a median follow-up duration of 29.5 months, the median progression-free survival and overall survival were 6.9 months (95% CI: 3.7, 9.3) and 17.6 months (95% CI: 12.4, not evaluated), respectively. The most common grade 3 treatment-related adverse events (≥10%) were neutropenia (25.8%) and diarrhea (16.1%). There was no treatment-related death. Conclusion: The combination of anlotinib and irinotecan has promising anti-tumor activity in the second-line treatment of mCRC with a manageable safety profile.
