Abstract
MSM are a high-risk population for HPV infection and related diseases. MSM can be effectively protected by quadrivalent and nine-valent HPV vaccines. This paper outlines the significance of providing HPV vaccination to MSM, summarizes the basis of HPV vaccination in MSM, and puts forward the following recommendations. First, China should expedite the development and approval of the HPV vaccine for male use. Second, HIV-positive MSM should vaccinate against HPV as soon as possible. Third, prioritize HPV vaccination for MSM individuals aged 26 or less. Fourth, for MSM aged over 26, catch-up vaccination or opportunistic vaccination should be provided when HPV vaccine resources are sufficient. Implementing this vaccination strategy can provide protection for the MSM and control the spread of sexually transmitted diseases.

Abstract
Objective: To investigate the prevalence of suicidal ideation among MSM, and to explore the influence of perceived social support and depression on suicidal ideation and the possible pathway. Methods: MSM who are ≥18 years, HIV-negative, and ever had sex with men (oral sex/anal sex) in the last year participated in is study. Cross-sectional survey and convenient sampling method were used to recruit MSM through a male social interaction platform Blued 7.5 software from December 2020 to March 2021, with a questionnaire survey. Demographic questionnaire, Perceived Social Support Questionnaire and Center for Epidemiologic Studies Depression Scale were employed to collect data. Mplus 8.3 was used for data analysis. Results: Among 1 394 eligible MSM participants, 25.7% (358/1 394) had suicidal ideation. Perceived social support could have a direct effect on suicidal ideation (β=-0.11, P=0.009), and an indirect effect on suicidal ideation through depression (β=-0.18, P<0.001). Conclusions: Suicidal ideation was found to be lower in MSM with a higher level of perceived social support and a lower level of depression. Using social media to improve MSM's perceived social support and reduce depressive symptoms might be an effective means to prevent suicidal ideation.

Abstract
Objective: To study the clinicopathologic characteristics and risk factors of sarcoma arising in fibrous dysplasia. Methods: A total of 18 cases were collected from January 2008 to July 2018 in Shanghai Jiaotong University Affiliated Sixth People's Hospital. The characteristics and the histologic type were retrospectively reviewed. IBM SPSS 19 was used for statistical analysis. Results: The male to female ratio of patients with fibrodysplastic sarcomatosis was 1.57∶1.00. The age of onset ranged from 24 to 87 years (mean 49 years). The long bones, especially the femur, were most frequently involved. Nine cases were osteosarcomas, three cases were high grade sarcoma and six cases were low grade sarcoma. Logistic regression analysis showed that age was an independent risk factor for sarcomatous change, compared with polyostotic or recurrent cases. Value of Wals was 13.61 (P<0.05), and odds ratio was 12.82,95% confidence interval was 3.31-49.70. Conclusions: Fibrodysplasia sarcomatosis is clinically nonspecific and the risk of sarcomatous changes increases approximately 12-fold when age of onset of fibrous dysplasia is over 40 years.

Abstract
Objective: To study the real-world outcome of China FDA-approved Sofosbuvir (SOF)/Velpatasvir (VEL) in Northwest China. Methods: In this multicenter, prospective, real-world cohort study, we recruited patients from 10 sites from Northwest China, who were chronically infected with HCV GTs 1-6 from 06/2018 to 09/2019. Patients received SOF (400mg)/VEL (100mg) for 12 weeks, and with ribavirin 900-1200 mg for GT3 cirrhosis and for any genotype decompensated cirrhosis. The primary endpoint was sustained virological response at 12-weeks post-treatment (SVR12) and safety. The secondary endpoint was the change of liver function after the achievement of SVR12. Results: Totally, 143 patients were enrolled in the study, four patients were lost to follow-up and one died during the follow-up, 138 patients were included in per-protocol analysis. Of the 138 patients, the mean age 53 years, 53.6% male, 94.2% Han nationality, 53.6% liver cirrhosis, 10.1% HBsAg(+), 6.5% renal dysfunction, 5.1% treatment-experienced, and 16.7% patients received ribavirin treatment. The genotype distribution was as follows: 35.5% GT1, 42.8% GT2, 15.9% GT3, and 5.8% un-typed. The SVR12 rate was 96.5% (138/143, 95%CI: 93.5%-99.6%) for intention-to-treat analysis, and in per-protocol analysis, all 138 patients obtained SVR12 (100%). Compared with baseline, the serum total bilirubin, ALT and AFP levels decreased (all P < 0.05), as well as increased ALB and platelet count (all P < 0.001) at post-treatment 12-weeks. Overall adverse events (AEs) rate is 29.0%, and the most common AEs were anemia (14.5%) and fatigue (8.0%). Severe side effects (edema and fatigue) occurred in 2 patients, one of whom needed a short-term interruption of treatment due to fatigue. Conclusion: In this real-world cohort study, 12-week SOF/VEL regimen with or without ribavirin achieved high SVR12 rates (96.5%-100% overall) with excellent safety profile among patients with HCV GT1/2/3 infection including patients with GT3 and cirrhosis, and led to improvement of liver function.

Abstract
Objectives: To explore the HIV prevalence and related factors among MSM aged 50 and above and provide evidence on the prevention and control of HIV/AIDS. Methods: Based on an MSM social application software Blued 7.1.6, we recruited participants through online convenience sampling to collect demographic variables, behavioral and self-reported HIV infection status, etc. Univariate χ2 test and multivariate logistic regression were used to analyze the related factors of self-reported HIV infection. Results: Self-reported HIV infection rate was 17.6%(126/714) among the participants. In multivariable analysis, participants who got divorced or widowed had a 2.07(95%CI: 1.34-3.21) times greater risk of self-reported HIV-positive than those who were married. Participants unaware of HIV-related knowledge showed a 1.92(95%CI:1.21-3.04) times greater risk of self-reported HIV-positive than those with better HIV-related knowledge. Participants who have ever been diagnosed with sexually transmitted disease (STD) showed a 3.17(95%CI:2.09-4.83) times greater risk of self-reported HIV-positive than those without STD infection history. Conclusion: Our findings indicated that the self-reported HIV infection rate was high among MSM aged 50 and above. Being divorced or widowed, being unaware of HIV-related knowledge and STD infection history was proved related with self-reported HIV infection.

Abstract
Objectives: To explore the GAA varient spectrum and the genotype-phenotype correlations in patients with glycogen storage disease type Ⅱ (Pompe disease, PD), as well as to estimate the disease incidence based on carrier rate of GAA varients in Guangzhou population. Methods: A total of 57 PD cases were retrospectively enrolled at Guangzhou Women and Children's Medical Center from January 1, 2010 to May 31, 2020. All patients presented symptoms before the age of 18 years. Each diagnosis was further confirmed by GAA enzyme activity and GAA variants. The carrier rate of GAA varients was calculated based on variants detected by whole exon sequencing among 2 395 healthy children in Guangzhou. Results: Among the 57 PD patients (including male 26, female 31),twenty-eight patients with infantile onset PD (IOPD) presented with progressive general muscle weakness and cardiomyopathy. The mean ages of symptom onset and diagnosis were (2.5±1.4) and (5.0±3.0) months, respectively. Twenty-six cases died in the first year after birth.Twenty-three patients with late onset PD (LOPD) presented with progressive muscle weakness. Seven of them had respiratory failure at diagnosis. The mean ages of symptom onset and diagnosis were (12.0±5.0) and (17.0±7.5) years, respectively. Six children with atypical IOPD showed motor delay, muscle weakness and cardiomyopathy. Their diagnosis was confirmed at 2.5-7.0 years of age. Among the 57 patients, 47 different variants were identified in the GAA gene. Three variants: c.797C>T, c.1109G>A and c.1757C>T were novel. c.1935C>A (25/114, 21.9%) and c.2238G>C (15/114, 13.2%) were the most common variants, detected in 57.1% of IOPD and 65.2% (15/23) of LOPD patients, respectively. Among the 28 IOPD patients, 26 cases (92.9%) carried at least one missense variant which indicated positive cross-reactive immunologic material (CRIM). The carrier rate of pathogenic variants in GAA gene among healthy children was 24/2 395. The estimated incidence of PD in this population is about 1/40 000. The frequencies of pseudodeficiency variants c.1726G>A and c.2065G>A homozygotes were 26.3% (15/57) and 35.1% (20/57) in PD patients, which were significantly higher than those (1.7% (40/2 395) and 3.9% (94/2 395)) in healthy children (χ²=151.2, 121.9; both P<0.01). Conclusions: PD presents as a spectrum, some as atypical IOPD. The c.1935C>A and c.2238G>C are common variants, correlated with IOPD and LOPD respectively. The c.796C>T and c.1082C>T are usually found in atypical IOPD. The majority of IOPD patients is predicted to be CRIM positive. The estimated incidence of PD is about 1/40 000.

Abstract
The unbalanced economic development, the lifestyle changes of the residents, the aging before getting rich and the burden of non-communicable chronic diseases in China have brought great pressure on China's health system. However, the prevention and control mechanism of chronic diseases in China is far from mature, which restricts the development of the prevention and control of chronic diseases in China. Singapore's new concept on chronic disease management and the the 3-level theoretical framework are good experience in the world and deserve to be learned by China. This article introduced the Healthy Living Master Plan in health promotion practice in Singapore, and made suggestions on construction of health management system to cope with the disease burden in China.

Abstract
OBJECTIVE To establish a reliable approach for measuring proximal femoral 3 dimensional anatomy, and to compare post-operative differences of proximal femoralanatomy in the inter-trochanter fractures with two kinds of antegrade nailings. METHODS Some computer assisted design (CAD) softwares, e.g. Mimics, were used to establish a reliable approach for measuring proximal femoral 3 dimensional (3D) anatomy. Intra-class correlation coefficient (ICC) was used to test the reliability of intra- and inter-observers. The post-operative pelvic CT data of 19 cases of inter-trochanter fracture patients treated with InterTAN nailing and 21 cases of inter-trochanter fracture patients treated with proximal femoral nail anti-rotation (PFNA) were retrospectively analysed and used to measure bilateral proximal femoral anatomical parameters, including 2D and 3D femoral neck-shaft (NS) angle and femoral neck anteversion (NA) angle, and 2D and 3D anteversion angles of the intramedullary (IM) nailings. ICC was used to test the consistency of the NA angles in the different groups, and the paired student T-test was used to test the differences of the paired quantitative data. RESULTS The established measurement method hasdexcellent consistency within the intra- and inter-observers, with all the ICCs higher than 0.9. The paired student T-test showed no significant difference between the post-operative bilateral 2D or 3D NA angles. The ICCs results showed that there were no consistency between the post-operative bilateral 2D or 3D NA angles (P values were 0.099 and 0.055, respectively), but the excellent consistency between the 2D injured side NA angle and 2D IM nailing's NA angle, or between the 3D injured side NA angle and 3D IM nailing's NA angle (the ICCs were 0.81 and 0.8, respectively, P values < 0.001). In PFNA group, 57% of the differences between the 2D post-operative injured side's and intact side's NA angles were higher than 15°, which was more than 15.78% in InterTAN group. The paired student T-test showed no significant difference between the post-operative injured side's 2D or 3D NS angles and the intact side's respective 2D or 3D angles in PFNA group (P values were 0.925 and 0.367, respectively), but in InterTAN group, the post-operative injured side's 2D or 3D NS angles were significantly smaller than the intact side's respective angles (P values were 0.033 and 0.009, respectively). CONCLUSION By analyzing and comparing bilateral proximal femoral anatomical parameters after two kinds of IM nailings procedures, the differences between the bilateral post-operative NA angles in PFNA group were significantly larger than those in InterTAN group. There was significant correlation between the NA angles of the injured sides and NA angles of IM nailings in both the groups.

Abstract
Condom use is often equated to safer sex. The prevalence of condom use during sex work among female sex workers (FSW) in China is high. Condom use, however, co-exists with condom failure and improper use and hence risk of HIV transmission. In a cross-sectional study, we interviewed 195 FSW in Shenzhen, China. The prevalence of condom use in the last episode of sex work was 97.4 %, However, respectively 53.8 and 86.2 % had experienced at least one condition of condom failure that may lead to genital contact (wearing condoms after penetration, condom breakage/slippage, condoms removed by clients) and at least one condition of improper condom use (not removing air from the tip of the condom, not pulling it down to the root of penis and not choosing good quality condoms). Factors of individual level (e.g. never choosing high quality condoms for sex work), inter-personal level (e.g. agreement to have unprotected sex if fond of clients or paid more) and environmental/structural level (e.g. non-availability of condoms) were associated with various types of condom failure and improper use. Although HIV prevention interventions have increased prevalence of condom use among FSW, the risk of HIV transmission may still be high as "unsafe" sex due to condom failure and improper use is prevalent. Interventions promoting safer sex need to address such issues and take socio-ecological factors into account. Condom use during sex work is not equivalent to well protected sex as the protective effects could be compromised by frequent condom failure and improper use.

Abstract
WHAT IS KNOWN AND OBJECTIVES Drug disposition may show ethnicity and gender differences. The objective of this study is to assess whether there are gender and ethnic differences in the pharmacokinetics of tramadol. METHODS Fifty healthy volunteers from five different ethnic Chinese groups (Han, Mongolian, Korean, Uygur and Hui) were recruited, and blood samples were obtained for up to 36 h after oral administration of a single 100 mg capsule of tramadol. The plasma concentration-time course of tramadol was measured by high-performance liquid chromatography and the pharmacokinetic estimated. RESULTS AND DISCUSSION The mean maximum plasma concentration (C(max)) of tramadol was different between Chinese males and females. There were also statistically significant differences between Hui and the other ethnic groups in tramadol's clearance (CL/F), volume of distribution (V(d) /F), C(max) and area under the plasma concentration time curve (AUC(0-∞)) (P < 0·05). WHAT IS NEW AND CONCLUSION The pharmacokinetics of tramadol was different in Hui subjects compared to the other Chinese ethnic groups. Tramadol CL/F may also show gender differences.

Abstract
Acute promyelocytic leukemia (APL) is characterized by typical morphological manifestation, t(15;17) translocation and active response to all-trans retinoic acid (ATRA) in the great majority of patients. However, a subset of APL cases may present atypical phenotypic, cytogenetic or molecular features at different stages of the disease. The biological and clinical significance of these features sometimes remains obscure. In this study, 284 APL patients were cytogenetically analyzed and precise diagnosis was performed according to the molecular cytogenetic results. Twenty-six APL patients were identified as having additional, complex and/or variant chromosomal abnormalities at diagnosis or at relapse, 16 of them being further analyzed using fluorescence in situ hybridization (FISH) or chromosome painting (CP). Interestingly, some of these chromosomal aberrations were found to be associated with atypical morphology and/or drug response, indicating a genotype-phenotype correlation. Analysis of the complex karyotype may also allow a better understanding of the levels of cellular origin of the leukemogenesis. Examination of the remission induction and survival data showed that the presence of the additional/complex chromosome abnormalities was related to the prognosis in both primarily diagnosed and relapsed patients in this series.

Abstract
OBJECTIVE To examine the relationship between total parenteral nutrition(TPN) and complication and death rates in surgical patients. DATA SOURCES A computer search of published research on MEDLINE, personal files and a review of relevant reference lists. STUDY SELECTION A review of 237 titles, abstracts or papers. Primary studies were included if they were randomized clinical trials of surgical patients that evaluated the effect of TPN (compared to no TPN or standard care) on complication and death rates. Studies comparing TPN to enteral nutrition (EN) were excluded. DATA EXTRACTION Relevant data were abstracted on the methodology and outcomes of primary studies. Data were independently abstracted in duplicate. DATA SYNTHESIS There were 27 randomized trials in surgical patients that compared the use of TPN to standard care (usual oral diet plus intravenous dextrose). When the results of these trials were aggregated, there was no effect on mortality (risk ratio = 0.97, 95% confidence intervals, 0.76 to 1.24). There were fewer major complications in patients who received TPN, although there was significant heterogeneity in the overall estimate (risk ratio = 0.81, 95% CI, 0.65 to 1.01). Because of this significant heterogeneity, several a priori hypotheses were examined. Studies that included only malnourished patients demonstrated a trend to a reduction in complication rates but no difference in death rate when compared with studies of patients who were not malnourished. Studies published in 1988 or earlier and studies with a lower methods score were associated with a significant reduction in complication rates and a trend to a reduction in death rate when compared with studies published after 1988 and studies with a higher methods score. There was no difference in studies that provided lipids as a component of TPN when compared with studies that did not. Studies that initiated TPN preoperatively demonstrated a trend to a reduction in complication rates but no difference in death rate when compared with studies that initiated TPN postoperatively. CONCLUSIONS TPN does not influence the death rate of surgical patients. It may reduce the complication rate, especially in malnourished patients, but study results are influenced by methodologic quality and year of publication.

Abstract
INTRODUCTION To study the relationship between the expression level of the PML-RARalpha fusion transcripts and the clinical status and efficiency of the therapy in acute promyelocytic leukemia (APL) patients, we applied a very sensitive and specific real-time Reverse Transcription Polymerase Chain Reaction (RT-PCR) system to quantify the dose of PML-RARalpha fusion transcripts in a series of APL patients at distinct disease stages. MATERIALS AND METHODS A total of 31 APL patients (19 males and 12 females; aged from 8 to 74 years) from eight hospitals in Shanghai were analysed. Real-time Quantitative RT-PCR was used to measure the normalized dose (DoseN) of PML-RARalpha fusion transcripts. RESULTS A wide range of PML-RARalpha DoseN above 1 x 10(3) was noted in 25 newly diagnosed patients. PML-RARalpha DoseN was significantly decreased after remission induction with ATRA, ATRA/chemotherapy or As2O3 and further reduced after consolidation. The fact that all patients with long disease free survival had a constantly low PML-RARalpha DoseN below 2 x 10(2) and a higher level predicted impending relapse suggests that this value could serve as a 'threshold' for molecular remission. PML-RARalpha DoseN was also of prognostic value in a group of relapsed patients, since good response to As2O3 reinduction was accompanied by a remarkable reduction of fusion transcript level, whereas patients with high PML-RARalpha Dose(N) after the second CR tended to relapse again rapidly. CONCLUSION These results confirm that real-time RT-PCR assay for PML-RARalpha transcripts in APL patients is useful in reflecting leukemic burden, assessing response to treatment and indicating the ultimate clinical outcome or curability of disease.

Abstract
Fifty-eight acute promyelocytic leukemia (APL) patients (11 newly diagnosed and 47 relapsed) were studied for arsenic trioxide (As2O3) treatment. Clinical complete remission (CR) was obtained in 8 of 11 (72.7%) newly diagnosed cases. However, As2O3 treatment resulted in hepatic toxicity in 7 cases including 2 deaths, in contrast to the mild liver dysfunction in one third of the relapsed patients. Forty of forty-seven (85.1%) relapsed patients achieved CR. Two of three nonresponders showed clonal evolution at relapse, with disappearance of t(15;17) and PML-RARalpha fusion gene in 1 and shift to a dominant AML-1-ETO population in another, suggesting a correlation between PML-RARalpha expression and therapeutic response. In a follow-up of 33 relapsed cases over 7 to 48 months, the estimated disease-free survival (DFS) rates for 1 and 2 years were 63.6% and 41.6%, respectively, and the actual median DFS was 17 months. Patients with white blood cell (WBC) count below 10 x 10(9)/L at relapse had better survival than those with WBC count over 10 x 10(9)/L (P =.038). The duration of As2O3-induced CR was related to postremission therapy, because there was only 2 of 11 relapses in patients treated with As2O3 combined with chemotherapy, compared with 12 of 18 relapses with As2O3 alone (P =.01). Reverse transcription polymerase chain reaction (RT-PCR) analysis in both newly diagnosed and relapsed groups showed long-term use of As2O3 could lead to a molecular remission in some patients. We thus recommend that ATRA be used as first choice for remission induction in newly diagnosed APL cases, whereas As2O3 can be either used as a rescue for relapsed cases or included into multidrug consolidation/maintenance clinical trials.

Abstract
To study the genomic abnormality underlying the acute transformation of chronic myeloid leukemia (CML), 15 CML patients in blast crisis (BC), 3 in accelerated phase (AP), and 20 in chronic phase (CP) were analyzed by conventional cytogenetics, comparative genomic hybridization (CGH), and dual-color chromosomal painting. Philadelphia (Ph) chromosome was identified in every case studied. Only 5 among 20 CP patients had additional abnormalities while 13 of 18 patients with disease progression (BC + AP) showed extra numerical and/or structural chromosomal aberrations. Cytogenetically, the most common chromosome gains during BC and AP were double or triple Ph chromosomes (5 of 14 cases) and trisomy 8 (5 of 14 cases). Trisomies 7 and 17 (1 of 14 cases each) were also observed. CGH analysis detected genetic imbalances in eight cases. Gains of chromosome 20 (3 cases) and 17q (2 cases) were observed, respectively. The recurrent chromosome loss was the deletion of the short arm of chromosome 17, seen in one case with i(17)(q10) and one case with an unbalanced translocation (1;17). In one case, a very complex chromosomal rearrangement, del(3),del(6),der(6)t(17;3;6),der(17)t(6;17), was seen. A novel finding of this work is the involvement of chromosome 1(q12-21qter) in CML disease progression. Overrepresentation of 1(q12-21qter) region was detected by CGH in one case which had a derivative chromosome 17. This abnormal chromosome was later confirmed by fluorescence in situ hybridization (FISH) painting to be a fusion between chromosome 1 and 17 to form the der(17)t(1;17) (q12-21;p11). Two other cases showed the same region being involved in translocations, t(1;10)(q12-21;q26) and t(1;11)(q12-21;p15). It is possible that one or more genes residing on chromosome 1q12-21 may be important in the acute transformation of CML. In conclusion, we find that the combined use of CGH, chromosome painting, and classic cytogenetic analysis allows a better evaluation of the genomic aberration involved in CML blastic transformation, and offers new directions for its further molecular investigations.

Abstract
Chromosomal analysis of acute lymphoblastic leukemia (ALL) is often difficult because of the suboptimal in vitro growth of the immature lymphoid cell and the poor morphology obtained. In this study, we describe the application of comparative genomic hybridization (CGH) to investigate the genomic abnormalities in 14 patients with ALL, all of whom had cytogenetically identified numerical aberrations or gross chromosomal structural alteration. With the use of CGH, regional or whole chromosome overrepresentation or both were found to be more frequent than underrepresentation (52 gains vs. 6 losses), the most common gains being chromosomes 21 and X. The results of the comparison between CGH and conventional R-banding analysis could be classified into three categories: (1) in three cases, including two with trisomy, CGH and banding analysis gave identical results; (2) in six cases with hyperdiploidy and two cases presenting chromosome structural abnormalities, the results were consistent but with minor discrepancies; (3) in three cases, including two with triploidy and tetraploidy and one with chimeric karyotype together with +22, the data from CGH and cytogenetical analysis were discrepant. CGH could not find the triploidy and tetraploidy. Our results suggest that CGH has certain value in the detection of gains or losses of chromosome materials in hyperdiploid ALL. Nevertheless, the combination of CGH and conventional karyotyping provides more precise information on the genomic imbalance in ALL.

Abstract
100 cases of patients under cancer chemotherapy were investigated by using Self-Rating Anxiety Scale (SAS) and questionnaire on coping patterns. The results showed that scores of SAS were significantly higher than that of the normal population. The state of the anxiety reached 45% among the patients. The patients' coping patterns tended to be passive. Linear analysis revealed a negative correlation between the coping patterns and the scores of SAS. It is recommended that cognitive behavioral therapy can be used to relieve the anxiety of patients under cancer chemotherapy.

Abstract
60 cancer patients during chemotherapy were investigated by using case-control study. 30 of them were recruited as the experiment group and given biofeedback relaxation training, the others were controls. Both of the two groups were assessed with SCL-90 and questionnaire on physical reactions. Results showed that no significant difference was found between the average scores of SCL-90 (including F1, F3, F4, F5, F10) of the two groups before the intervention. However, lower average scores and less serious physical reactions (4 of the 6 items) were seen from the experiment group after the intervention. It is indicated that biofeedback relaxation training is effective in alleviating patient's unhealthy psychosomatic reactions during chemotherapy.

Abstract
We present a method that uses two groups of fringe patterns on one grating for phase-measuring profilometry. A two-frequency grating is projected onto the object. The high frequency is N (N = 3, 4, 5, :...) times greater than the low frequency. Using a proper phase shift, we calculated the wrapped phases of the two frequencies. When the linearity of the two phases are considered, an accurate phase of the high frequency can be unwrapped. Because the low frequency is N times more insensitive to height discontinuity, the system is more tolerable to height discontinuity.

Abstract
Two types of markers, namely the clone-specific markers including T-cell receptor (TCR) gamma, TCR delta, and Ig heavy-chain (IgH) gene rearrangements, and malignancy-specific fusion gene mRNA such as SIL-TAL-1, BCR-ABL, and HRX-partner genes, were investigated by molecular biology techniques in 65 Chinese patients with acute lymphoblastic leukemia (ALL). In combination, these markers were informative among 96% of patients. Minimal residual disease (MRD) was followed up in 23 of these patients with available materials over a period varying from 8 to 54 months with at least one leukemia-specific probe. In most children, MRD was decreased continuously to an ultimately undetectable level within 6 to 12 months after remission induction therapy. One patient exhibited low-level residual leukemic cells for 4 years before the MRD turned negative. Another patient remained in complete remission for 45 months, although a positive signal was detected at 34 months using TCR delta probe, but was negative with a TCR gamma marker which was positive at presentation. In three patients who relapsed, MRD either persisted through the clinical course or became positive and eventually increased 3-11 months before clinical relapse. These data suggested that the combined use of multiple gene markers is a valuable tool for the PCR-based MRD detection, since it can cover most ALL patients. Furthermore, long-term follow-up of MRD is helpful for determining the dosage as well as the period of maintenance chemotherapy and for predicting impending relapse.

Abstract
OBJECTIVE To compare an empirical Bayesian, a fully Bayesian, and a classical fixed-effect (Peto) method for pooling event rates from separate epidemiologic studies or clinical trials. DESIGN Four data sets used in meta-analyses by previous authors were evaluated. The first data set concerned death rates observed in clinical trials of beta-blockers, the second to lung cancer and smoking in 14 case-control studies, the third to drowsiness induced by the antihistamine compound chlorpheniramine, and the fourth to the use of intravenous magnesium in patients with suspected myocardial infarction. Randomly chosen data points were made more extreme to test the methods further. MAIN OUTCOME MEASURES Pooled estimates of effect expressed as odds ratios and their associated 95% confidence intervals. RESULTS All three methods gave comparable results with respect to the 95% confidence interval, although the Bayesian methods gave generally wider interval estimates. However, the point estimates for the individual studies were substantially different, particularly for small studies. CONCLUSIONS For the data sets considered, Bayesian methods, which are computer intensive but intuitively appealing, provided results that were consistent with the classic fixed-effect Peto method. Introduction of the more extreme data points did not alter this conclusion.

Abstract
Systematic errors in phase-measuring profilometry that are introduced by the modulation transfer function of a digital image-acquisition device are analyzed. New phase expressions and phase-deviation formulas are given. The results for simulations and experiments demonstrate that the algorithm of phase-measuring profilometry cannot be regarded as a point-to-point operation. To obtain precise results, an optimum scheme for setting the measurement system is also proposed.

Abstract
The use of a bayesian method for estimating the shelf-life of pharmaceutical formulations is evaluated and compared with classical linear regression. Using three real data sets, the greater flexibility provided by the bayesian approach is demonstrated. In particular, the bayesian approach enabled the consideration of cases when the error distribution is non-normal. However much more computation is required with the bayesian method.

Abstract
The effects of azelastine (0.1%) nasal spray (Rhinolast) on ciliary beat frequency are investigated and compared with those of oxymetazoline hydrochloride (Vicks Sinex), xylometazoline (Otrivine) and ephedrine hydrochloride (0.5%). It is shown that all four formulations exert a ciliotoxic effect. The antihistamine (azelastine) and the two long-acting alpha sympathomimetic decongestants (xylometazoline and oxymetazoline) had comparable effects which were milder than those observed with ephedrine, the less specific alpha and beta sympathomimetic agent. The results suggest that the intranasal application of all four products should be restricted to short-term therapy. Oral antihistamine therapy and not topical therapy should still be the first-line therapy for antihistamine-responsive rhinitis until non-ciliotoxic formulations can be developed.

Abstract
Methyl methanesulfonate (MMS 75 mg.kg-1)-induced unscheduled DNA synthesis (UDS) was inhibited significantly in the spermatozoa of mice injected with Poly I-C (0.05, 0.50, and 5.00 mg.kg-1) at 4 h prior to ip MMS. Radioactivity was reduced from 53 +/- 3 to 50, 45 +/- 5, and 34 +/- 6 dpm/million sperms respectively. The effects of Poly I-C were dose-dependent (r = 0.9498, P less than 0.05) in inhibition of MMS-induced UDS. The effect of serum collected from the mice injected with Poly I-C (0.50 mg.kg-1) had similar effects as that of Poly I-C. Our findings suggest that both Poly I-C alone and mouse serum induced with Poly I-C may prevent the DNA damage produced by MMS.
