OBJECTIVES: This study was carried out to determine the role of p53 and p21 in the pathogenesis of prostatic adenocarcinoma and their association with tumour grade. METHOD: Sixty-seven histologically confirmed prostatic adenocarcinoma cases collected from Hospital Universiti Kebangsaan Malaysia and General Hospital Kuala Lumpur were studied. The formalin-fixed paraffin-embedded tissues were stained with monoclonal antibody p53 (clone DO-7) and p21 (clone SX II8) using standard avidin-biotin complex immunohistochemistry (IHC) after microwave antigen retrieval. The adenocarcinomas were graded histologically according to Gleason score: low grade = score 2-4, intermediate grade = score 5-7, high grade = score 8-10. Histological grade was analysed against IHC expressions of p53 and p21 and against patient age and ethnicity. RESULTS: IHC positivity for p53 was expressed in 1/2 (50%) low grade, 14/33 (42%) intermediate grade, and 21/32 (66%) high grade tumours. p21 was expressed in 0/2 low grade, 16/33 (48%) intermediate grade and 15/32 (47%) high grade tumours. p53 and p21 expressions did not show statistically significant correlation with the different grades of prostatic adenocarcinoma or with each other (p = 0.42). There was no correlation between tumour grade and age or ethnicity. CONCLUSION: Although the p53 positivity rate was higher in high-grade prostate adenocarcinoma, this was not statistically significant. We found that a combined expression of p21 and p53 was not correlated with tumour grade. We could not confirm that p21 expression was dependent on p53 expression.

2.Traditional medicinal knowledge in Lancang-Mekong River:a case study in Lancang Lahu autonomous county.
China Journal of Chinese Materia Medica 2021;46(24):6331-6342
Lancang Lahu autonomous county, where the Lancang-Mekong River flows by, was selected as the case site to investigate the traditional medicinal knowledge(TMK). A comparison of TMK between Lancang county and other places in the Lancang-Mekong sub-region was conducted. Research on TMK has been seldom reported although there are abundant medicinal resources in this sub-region. The key informant interview and other methods have been adopted in the field surveys in the past six years. The investigation revealed that there was rich TMK and various herbal medicine resources in Lancang county. A total of 220 folk prescriptions have been collected, which were normally simple with easy processing methods and usages, and most raw materials were freshly used. As for medicinal plants, 121 species in 67 families have been documented. Other findings included that TMK in Lancang county was remained at the level of medication based on experience only. The processing methods of herbal medicines were simple and the bioactive ingredients were not clear. Without text and cultural support for self-teaching, coupled with conservative inheritance, it resulted in massive losses of TMK. The folk doctors have accumulated their factions based on self-study or ancestral experience. There was different treatment experience among folk doctors, but the safety and effectiveness should be paid attention to. The folk doctors used various herbal medicines, but there was a lack of standards or specifications for quality control. Given the problems existing in inheritance and development, conservation strategies were proposed in the present study.

OBJECTIVE:
To explore the pathogenic variants and clinical classification of two fetuses with Short-rib thoracic dysplasia with or without polydactyly (SRTD).
METHODS:
With informed consent obtained, the phenotypic characteristics of the fetuses were comprehensively examined, and genomic DNA was extracted from fetal skin tissue and peripheral blood samples of the parents with conventional phenol-chloroform method. Whole exome sequencing (WES) was carried out on both fetuses, and the candidate variants were validated by Sanger sequencing. The pathogenicity of the candidate variants was analyzed using bioinformatic software VarCards, and the impact of the variants on the protein structure was predicted with Swiss-Pdb-viewer.
RESULTS:
Both fetuses were found to harbor compound heterozygous variants of the DYNC2H1 gene, including c.515C>A (p.Pro172Gln) and c.5983G>A (p.Ala1995Thr) in fetus 1, and c.5920G>T (pGly1974) and c.9908T>C (p.He3303Thr) in fetus 2. The parents of both fetuses were heterozygous carriers.
CONCLUSION
The compound heterozygous variants of the DYNC2H1 gene probably underlay the SRTD3 in the two fetuses.

A cross-sectional study was conducted to determine the physical activity levels of 400 adolescents (13 years old) in Kuantan, Pahang using the Physical Activity Questionnaire for Older Children (PAQ-C). The associations of physical activity levels with sex, ethnicity and body mass index were also determined. About one third (35.3%) of the adolescents were in the low physical activity level category, 61.5% in the moderate physical activity level and only 3.0% of the adolescents were in the high physical activity level category. More males (77.9%) were physically active than females (54.9%). Twice as many female adolescents (45.1%) were in the low physical activity level category compared to the male adolescents (22.1%). The associations between physical activity with ethnicity and body mass index were not significant. However, there was a significant interaction effect of sex and ethnicity in mean physical activity score (F = 2.36, p<0.01). Malay males had a significantly higher mean physical activity score as compared to Chinese males (t=2.13; p<0.05). Although Chinese females had a higher mean physical activity score than Malay females, the difference was not statistically significant. Conversely, there was no interaction effect of sex and BMI status in mean physical activity score. This study suggests that physical activity intervention to promote regular physical activity is needed since a high proportion of the adolescents fall within the low physical activity level category.

"Unblocking fu organs" is one of the essential principles of Ma's warm moxibustion technique, characterized as "dredging" and "harmonizing" for either deficiency or excess condition. Under the guidance of this therapeutic thought, the acupoints for moxibustion are mainly selected from the middle and lower parts of the body. Regarding the therapeutic approach, the acupoint prescription for moxibustion should be formed in line with warming and promoting circulation of fu organs; the moxibustion degree should be specially considered, in which, the mild moxibustion is recommended to induce promoting action; and the systematic moxibustion technique should be the root for dredging fu organs and regulating zang organs. Ma's mild moxibustion technique stresses on removing the obstruction of fu organs and emphasizes promoting the qi activity of sanjiao (triple energizer) and regulating the balance of five zang organs.

Objective To analyze the characteristics of the bilateral external ears of Uygur adults by directly observing the morphological characteristics of the external ears of Uygur adults and classifying each feature. The frequency distribution of the characteristics was calculated to provide reference for forensic identification. Methods The 210 cases (75 males and 135 females) of bilateral external ear photos of Uygur adults in Xinjiang that met the inclusion criteria were collected. The frequencies of the features of the external ear were recorded and distinguished between the two sexes and the different sides. The data were statistically analyzed by SPSS 21.0 statistical software. Results The shapes of the external ears of males and females were commonly oblique or rectangular (34.67% of the left external ear of males and 41.33% of the right were oblique; 30.37% of the left and right external ear of females were rectangular), while triangular ears were the rare variants and the least common. Sex and bilateral differences were observed as regards the form of the helix in the subjects. Normally rolled helix was the most common (58.67% males and 61.48% females for the left ear; 60.00% males and 72.59% females for the right ear). Wide covering scapha helix was the most rare for the male left ear and flat helix was the most rare for the female right ear. Square and free earlobes were the most common (49.33% males and 62.96% females for the left ear; 40.00% males and 54.81% females for the right ear), whereas triangular earlobes were rarely seen. Single knob tragus (40.00% males and 37.78% females for the left ear; 37.33% males and 33.33% females for the right ear) and projection type of Darwin's tubercle (50.67% males and 40.00% females for the left ear; 48.00% males and 39.26% females for the right ear) were found to be common. Conclusion The characteristics of the bilateral external ears of male and female Uygur adults have differences, which can be used for forensic identification.

Background:
Background: Urinary incontinence is a common problem among older women. The objective of this study was to determine the prevalence of urinary incontinence among older women aged 55 years and over in the Klang valley, the most densely populated urban area in Malaysia, and to determine any potential ethnic differences.
Methods:
This study used cross-sectional data from the Malaysian Elders Longitudinal Research (MELoR) study. A total of 863 participants were included, with a mean age of 67.97 ± 7.50 (S.D.). They were selected by simple random sampling from the electoral rolls of three parliamentary constituencies.
Results:
The prevalence of urinary incontinence was 30.8%. Mixed urinary incontinence (UI) was present in 44.7%, stress UI in 39.1% and urge UI in 16.2%. Ethnic Malays (38%) were more likely than ethnic Indians (32.3%) and Chinese (29.7%) to have UI. Ethnic Malays were also more likely to have stress UI and Indians were more likely to have urge UI .
Conclusion
The prevalence of UI in this study was comparable to other Asian and worldwide studies. The significant association between ethnicity and UI, however, has not been reported in any previous studies. Further studies should identify factors which may determine these ethnic differences in UI.

OBJECTIVE:
To compare the expression patterns of microRNA (miRNA) between 144 Uygur and Han women with endometrial carcinoma and to investigate their clinical significance.
METHODS:
Taqman miRNA low-density array was used to compare miRNA profiles between Uygur and Han women with non-endometrioid endometrial carcinoma (NEEC). Five miRNAs were further analyzed in the 144 endometrial cancers including 62 Uygur and 82 Han samples via real-time PCR to determine their expression patterns.
RESULTS:
MiRNA expression profiles revealed that many miRNAs overexpressed or downregula-ted in one ethnic group, but did not express or changed slightly in the other ethnic group. Further detection in the 144 endometrial cancers showed that miR-141, miR-200a, and miR-205 overexpressed in both ethnic groups. In Uygur endometrioid endometrial carcinoma (EEC), tumors with miR-141/200a overexpression tended to be more aggressive in behavior, whereas in the Han group, EEC with miR-200a overexpression was relative mild. However, the NEEC with miR-200a overexpression also had aggressive clinicopathologic features in the Han women. MiR-145 and miR-143 expressed differentially between Uygur and Han groups, they overexpressed in the former and decreased in the latter (P<0.05). In the Uygur women miR-145/143 increased significantly in NEEC and there was a trend that NEEC exhibiting favorable clinicopathologic factors had higher miR-145 expression, and was statistically significant in tumors with myometrial invasion less than 1/2 thickness (P=0.042). By contrary, miR-145/143 decreased in Han group and EEC with worse clinicopathologic variables had lower expression although without statistical significance. NEEC in Han group had no such tendency.
CONCLUSION
Uygur and Han women might have different miRNA expression profiles. MiR-141/200a/205 overexpressed in endometrial carcinomas and miR-141/200a might behave differently between these two ethnic groups as well as in EEC and in NEEC. Although miR-145/143 showed inverse expression patterns between Uygur and Han women with endometrial cancer, they all exerted tumor suppression effect on endometrial cancer.

Journal of Integrative Medicine 2023;21(2):159-167
BACKGROUND:
Chiropractic is the largest complementary and alternative medicine profession in the United States, with increasing global growth. A preliminary literature review suggests a lack of widespread diversity of chiropractic patient profiles.
OBJECTIVE:
There have been no prior studies to comprehensively integrate the literature on chiropractic utilization rates by race, ethnicity, and socioeconomic status. The purpose of this scoping review is to identify and describe the current state of knowledge of chiropractic utilization by race, ethnicity, education level, employment status, and income and poverty level.
SEARCH STRATEGY:
Systematic searches were conducted in PubMed, Ovid MEDLINE, Cumulative Index of Nursing and Allied Health Literature (CINAHL), Cochrane Database of Systematic Reviews, and Index to Chiropractic Literature from inception to May 2021.
INCLUSION CRITERIA:
Articles that reported race or ethnicity, education level, employment status, income or poverty level variables and chiropractic utilization rates for adults (≥18 years of age) were eligible for this review.
DATA EXTRACTION AND ANALYSIS:
Data extracted from articles were citation information, patient characteristics, race and ethnicity, education level, employment status, income and poverty level, and chiropractic utilization rate. A descriptive numerical summary of included studies is provided. This study provides a qualitative thematic narrative of chiropractic utilization with attention to race and ethnicity, education level, income and poverty level, and employment status.
RESULTS:
A total of 69 articles were eligible for review. Most articles were published since 2003 and reported data from study populations in the United States. Of the race, ethnicity and socioeconomic categories that were most commonly reported, chiropractic utilization was the highest for individuals identifying as European American/White/non-Hispanic White/Caucasian (median 20.00%; interquartile range 2.70%-64.60%), those with employment as a main income source (median utilization 78.50%; interquartile range 77.90%-79.10%), individuals with an individual or household/family annual income between $40,001 and $60,000 (median utilization 29.40%; interquartile range 25.15%-33.65%), and individuals with less than or equal to (12 years) high school diploma/general educational development certificate completion (median utilization 30.70%; interquartile range 15.10%-37.00%).
CONCLUSION
This comprehensive review of the literature on chiropractic utilization by race, ethnicity and socioeconomic status indicates differences in chiropractic utilization across diverse racial and ethnic and socioeconomic populations. Heterogeneity existed among definitions of key variables, including race, ethnicity, education level, employment status, and income and poverty level in the included studies, reducing clarity in rates of chiropractic utilization for these populations.
