Objective To observe the effect of stage-based acupuncture-moxibustion therapy on the endometrial thickness in patients suffering from repeated implantation failure in IVF-ET (in vitro fertilization and embryo transfer). Method Seventy-two patients suffering from repeated implantation failure in IVF-ET were randomized into two groups. Thirty-six cases in the treatment group were intervened by stage-based acupuncture-moxibustion therapy plus oral administration of Estradiol valerate tablets; the other 36 cases in the control group were prescribed with oral administration of Estradiol valerate tablets alone. The implantation result of IVF-ET was analyzed 3 cycles later. The endometrial thickness was compared before and after the intervention. Result The endometrial thickness of the non-pregnant women increased after the treatment in both groups (P<0.05), and the increase in the treatment group was more significant than that in the control group (P<0.05). The clinical pregnancy rate in the treatment group was significantly higher than that in the control group (P<0.05). Conclusion Stage-based acupuncture-moxibustion therapy can improve the endometrial thickness, promote the growth of endometrium, benefit the implantation of embryo, and enhance the clinical pregnancy rate.

BACKGROUNDHer-2/neu gene overexpression has been found in several malignancies, and is associated with poor prognosis; while its role in the tumorigenesis and progression of prostate cancer (PCa) is still controversial. This study aimed to evaluate the prognostic value of Her-2/neu protein expression and clinicopathologic factors in antiandrogen-treated Chinese men with PCa for disease progression and PCa-specific death.

METHODSHer-2/neu protein expression was determined using immunohistochemistry (IHC) in specimens collected from 124 prostate biopsies and transurethral resection of prostate (TURP) from seven prostate cancer patients.

RESULTSHer-2/neu protein expression was 0, 1+, 2+, and 3+ in 40 (30.5%), 8 (6.1%), 67 (51.1%), and 16 (12.2%) cases, respectively. Her-2/neu protein expression showed significant correlation as judged by Gleason score (P = 0.049), clinical tumor-node-metastases (cTNM) stage (P = 0.018) and disease progression (P = 0.001), but did not correlate with prostate-specific antigen (PSA) (P = 0.126) or PCa-specific death (P = 0.585). PSA (P = 0.001), Gleason score (P = 0.017), cTNM (P = 0.000) and Her-2/neu protein expression (P = 0.001) had prognostic value for evaluating the progression of PCa in univariate analysis. In Kaplan-Meier plots, both Gleason score (P = 0.035) and cTNM (P = 0.013) correlated with PCa-specific death. In multivariate analysis, only cTNM was significant for both disease progression (P = 0.001) and PCa-specific death (P = 0.031).

CONCLUSIONSHer-2/neu protein expression is significantly correlated with Gleason score, cTNM and disease progression, although it is not an independent predictor of disease progression and PCa-specific death. cTNM staging serves as an independent prognostic factor for disease progression and PCa-specific death.

Species identification using DNA sequences is the basis for DNA taxonomy. In this study, we sequenced the ribosomal large-subunit RNA gene sequences (3,037-3,061 bp) in length of 13 Chinese Theileria stocks that were infective to cattle and sheep. The complete 28S rRNA gene is relatively difficult to amplify and its conserved region is not important for phylogenetic study. Therefore, we selected the D2-D3 region from the complete 28S rRNA sequences for phylogenetic analysis. Our analyses of 28S rRNA gene sequences showed that the 28S rRNA was useful as a phylogenetic marker for analyzing the relationships among Theileria spp. in ruminants. In addition, the D2-D3 region was a short segment that could be used instead of the whole 28S rRNA sequence during the phylogenetic analysis of Theileria, and it may be an ideal DNA barcode.

OBJECTIVETo evaluate the consciousness of health emergency and the abilities on self- and mutual medical aids among the public at the community level, as well as the community responses on health-related emergencies and other factors.

METHODSRandom equidistant sampling method was used to extract 617 households before choosing a family member sampled by Kish Grid method. All the members were investigated face to face on a questionnaire-"Health emergency and related ability regarding self and mutual medical aids of the residents". Data were entered into computer database by using software Epi Data 3.1 and were analyzed by SPSS 21.0.

RESULTSAmong the 617 households under survey, 47.84% of the public had general awareness on health-related emergencies. Regarding the following items as:prevention and isolation strategies of infectious disease, on safely procedures of earthquake and fires, on prevention of food poisoning, on prevention and first aid of emerging infectious diseases etc., the rates of awareness were 65.04%, 62.92%, 43.62% and 18.79% respectively. Proportions of households which had the first aid supplies were:first aid medicine box as 56.08%; fire extinguisher as 43.60%; spare water and food as 39.40%; having facilities as ropes, whistles and smoke masks for escape were all less than 15%. Rates of awareness on the following items as: correct use of gas switch as 81.52%, knowing the location of the circuit with gear and the fire hydrant as 74.39% and 35.98% , respectively. The correct disposal rates of the residents on the following items were:electric shock and falls (89.63%), patients of infectious diseases (83.31%), gas poisoning (82.98%), suspected symptoms on infectious diseases(82.66%), explosion and burns (66.78%), scald (62.72%)and sprain (57.05%). Scores on the related abilities were as follows: emergency(7.65, out of 10 points), escape(3.55, out of 5 points), self- and mutual medical aids (10.71, out of 16 points). Proportions of having learned and applied of first aid techniques among residents on the following items were:artificial breathing, chest compressions and cardiopulmonary resuscitation were all less than 10%. Level of knowing the first aid techniques was correlated with age and culture of the residents (P < 0.05).

CONCLUSIONBoth consciousness on health emergency and the abilities on self- and mutual medical aids were low among the community public, suggesting that both the government and pubic should pay more attention to the role of the abilities on self- and mutual medical aids.

BACKGROUND: Multifocal motor neuropathy (MMN), Lewis-Sumner syndrome (LSS), and many chronic inflammatory demyelinating polyradiculoneuropathies (CIDPs) are representative of acquired multifocal polyneuropathy and are characterized by conduction block (CB). This retrospective study aimed to investigate the demyelinating distribution and the selective vulnerability of MMN, LSS, and CIDP with CB (CIDP-CB) in nerves. METHODS: Fifteen LSS subjects (107 nerves), 24 MMN subjects (176 nerves), and 17 CIDP-CB subjects (110 nerves) were included. Their clinical information was recorded, blood and cerebrospinal fluid tests were conducted, and nerve conductions of the median, ulnar, radial, peroneal, and tibial nerves were evaluated. CB, temporal dispersion, distal motor latency (DML), and F-wave latency were recorded, and nerve conduction velocity, terminal latency index, and modified F-wave ratio were calculated. RESULTS: CB was more likely to occur around the elbow in CIDP-CB than in MMN (78.6% vs. 6.8%, P < 0.01) but less likely to occur between the wrist and the elbow than in LSS (10.7% vs. 39.3%, P < 0.05). Tibial nerve CB was most frequently observed in MMN (47.4%, P < 0.05). CIDP-CB was characterized by a prolonged DML in all nerves, and slow motor nerve velocity of the upper limb was significant when CB nerves were excluded (P < 0.05). CONCLUSIONS We report the different distributions of segmental and diffuse demyelination of the ulnar and tibial nerves in LSS, MMN, and CIDP-CB. These distinct distributions could help in differentiating among these conditions.

OBJECTIVE: To investigate the anti-coronavirus potential and the corresponding mechanisms of the two ingredients of Reduning Injection: quercetin and luteolin. METHODS: A pseudovirus system was designed to test the efficacy of quercetin and luteolin to inhibit SARS-CoV-2 infection and the corresponding cellular toxicity. Luteolin was tested for its activities against the pseudoviruses of SARS-CoV-2 and its variants. Virtual screening was performed to predict the binding sites by Autodock Vina 1.1.230 and PyMol. To validate docking results, surface plasmon resonance (SPR) was used to measure the binding affinity of the compounds with various proteins of the coronaviruses. Quercetin and luteolin were further tested for their inhibitory effects on other coronaviruses by indirect immunofluorescence assay on rhabdomyosarcoma cells infected with HCoV-OC43. RESULTS: The inhibition of SARS-CoV-2 pseudovirus by luteolin and quercetin were strongly dose-dependent, with concentration for 50% of maximal effect (EC₅₀) of 8.817 and 52.98 µmol/L, respectively. Their cytotoxicity to BHK21-hACE2 were 177.6 and 405.1 µmol/L, respectively. In addition, luetolin significantly blocked the entry of 4 pseudoviruses of SARS-CoV-2 variants, with EC₅₀ lower than 7 µmol/L. Virtual screening and SPR confirmed that luteolin binds to the S-proteins and quercetin binds to the active center of the 3CLpro, PLpro, and helicase proteins. Quercetin and luteolin showed over 99% inhibition against HCoV-OC43. CONCLUSIONS The mechanisms were revealed of quercetin and luteolin inhibiting the infection of SARS-CoV-2 and its variants. Reduning Injection is a promising drug for COVID-19.

OBJECTIVE: To analyze the prevalence, genotype distribution and hematological characteristics of α,β-thalassaemia carriers in Huizhou area of Guangdong Province. METHODS: 10 809 carriers of simple β-thalassaemia and 1 757 carriers of α,β-thalassaemia were enrolled as our study cohort. The hematological parameters were detected by automated blood cell counters and automatic capillary electrophoresis. Suspension array technology, gap-polymerase chain reaction (gap-PCR) and PCR-reverse dot blot were used for the genotyping of thalassaemia carriers. RESULTS: The prevalence of α,β-thalassaemia in Huizhou area of Guangdong Province was 1.99%. A total of 62 genotypes were detected, and the most prevalent genotype was --^SEA/ αα, β^CD41-42/ β^N (19.29%), the next was --^SEA/ αα, β^IVS-II-654/ β^N (16.73%). Significant differences in mean corpuscular volume (MCV) and mean corpuscular hemoglobin (MCH) were found between different genotype groups for simple β-thalassaemia and α,β-thalassaemia. Violin plots showed that carriers with co-inheritance of β-thalassaemia and mild α-thalassaemia expressed the lightest anemia, and carriers with co-inheritance of β-thalassaemia and hemoglobin H (Hb H) disease expressed the most severe anemia. CONCLUSION There is a high prevalence of α,β-thalassaemia in Huizhou area of Guangdong Province. Because of the lack of specific hematological makers for diagnosis of α,β-thalassaemia, it is necessary to distinguish it from simple β-thalassaemia by genotyping of α- and β-thalassaemia in order to correctly guide genetic counseling and prenatal disgnosis.
