Avian trichomoniasis caused by Trichomonas gallinae is a serious protozoan disease worldwide. The domestic pigeon (Columba livia domestica) is the main host for T. gallinae and plays an important role in the spread of the disease. Based on the internal transcribed spacers of nuclear ribosomal DNA of this parasite, a pair of primers (TgF2/TgR2) was designed and used to develop a PCR assay for the diagnosis of T. gallinae infection in domestic pigeons. This approach allowed the identification of T. gallinae, and no amplicons were produced when using DNA from other common avian pathogens. The minimum amount of DNA detectable by the specific PCR assay developed in this study was 15 pg. Clinical samples from Guangzhou, China, were examined using this PCR assay and a standard microscopy method, and their molecular characteristics were determined by phylogenetic analysis. All of the T. gallinae-positive samples detected by microscopic examination were also detected as positive by the PCR assay. Most of the samples identified as negative by microscopic examination were detected as T. gallinae positive by the PCR assay and were confirmed by sequencing. The positive samples of T. gallinae collected from Guangzhou, China, were identified as T. gallinae genotype B by sequencing and phylogenetic analyses, providing relevant data for studying the ecology and population genetic structures of trichomonads and for the prevention and control of the diseases they cause.

OBJECTIVETo compare the effects between felodipine plus irbesartan and felodipine plus metoprolol regimen on blood pressure and the sexual function in young and middle-aged hypertensive women.

METHODSIn this prospective, randomized, parallelized, controlled and fixed combined therapy trial, 99 female patients (aged 18 to 60) with grade 1 and grade 2 hypertension (BP ≥ 140/90 mm Hg and < 179/109 mm Hg, 1 mm Hg = 0.133 kPa) were assigned to felodipine 5 mg q.d + irbesartan 150 mg q.d (F + I group, n = 49) and felodipine 5 mg q.d + metoprolol 47.5 mg q.d (F + M group, n = 50) group. Target blood pressure was < 140/90 mm Hg. The female sexual function index (FSFI) questionnaire, levels of serum estradiol and testosterone were assessed. Female sexual dysfunction was defined as a FSFI score of less than 25.5. Patients were followed up for 24 weeks.

RESULTSThe rate of achieving blood pressure goal between 2 groups was similar at the 4th, 8th, 12th and 24th weeks respectively (42.9% vs. 62.0% at 4th week, 89.8% vs. 90.0% at 8th week, 93.9% vs. 94.0% at 12th week, 98.0% vs. 96.0% at 24th week, P > 0.05). Compared to baseline, scores for the items related to "desire" and "arousal" were significantly improved (P < 0.05), the level of the serum estradiol was significantly elevated [(50.3 ± 37.4) pg/L vs. (54.4 ± 10.8) pg/L before menopause, (18.4 ± 2.9) pg/L vs. (20.2 ± 3.1)pg/L after menopause, P < 0.05] and the level of the serum testosterone was significantly decreased [(722.8 ± 277.1) ng/L vs. (650.0 ± 156.0) ng/L before menopause, (841.2 ± 279.3) ng/L vs. (761.9 ± 197.8) ng/L after menopause, P < 0.05] in the F + I group, while scores for the items related to "sexual desire" and "lubrication" were statistically reduced (P < 0.01), the concentration of the serum estradiol was significantly reduced [(57.4 ± 9.7) pg/L vs. (51.1 ± 12.1) pg/L before menopause, (19.8 ± 2.3) pg/L vs. (17.8 ± 3.3) pg/L after menopause, P < 0.01] and the level of the serum testosterone was significantly increased [(775.6 ± 217.8) ng/L vs. (886.0 ± 186.4) ng/L before menopause, (812.5 ± 311.3) ng/L vs. (914.4 ± 300.2) ng/L after menopause, P < 0.01] in the F + M group. FSFI score was negatively correlated with age and systolic blood pressure levels.

CONCLUSIONfelodipine plus irbesartan or metoprolol for 24 weeks equally reduced blood pressure and the former regimen is superior to the latter on sexual function improvement in this patient cohort.

OBJECTIVETo investigate the clinical response, pathological complete response (pCR), tumor resection rate and safety of neoadjuvant chemotherapy with docetaxel and epirubicin (ET) for locally advanced breast cancer (LABC).

METHODSFrom March to December 2001, 40 women with LABC, aged from 28-67 (medium 48) years were alloted. Twenty patients had clinical stage IIIa disease, 15 had stage IIIb disease and 5 stage IV patients who had ipsilateral sura-clavicular metastasis. The dose was: epirubicin (E) 60 mg/m2, docetaxel (T) 75 mg/m2 every 3 weeks, with G-CSF given preventively. After 2 cycles of ET, a pilot clinical response evaluation was performed by investigators for each patient to decide if she should receive another 1-2 cycles of ET before surgery or radiation therapy.

RESULTSThirty-eight patients received 2-3 cycles of ET regimen. The pCR, clinical complete response (cCR) and clinical partial response (cPR) rates were 15.0%, 20.0% and 52.5%, respectively. Tumor resection rate in this group was 92.5%. Incidence of III/IV Grade neutropenia was 8.4%/14.0% of cycles, and 3 patients suffered from neutropenia with fever. Non-hematological adverse events were alopecia, nausea, vomiting, fluid retention, myalgia, arthralgia and nail disorders, which were mild to moderate.

CONCLUSIONNeo-adjuvant chemotherapy with a combination of docetaxel and epirubicin is effective and well tolerated by women with locally advanced breast cancer.

BACKGROUNDThe genioglossus (GG) is involved in the maintenance of an open airway for effective breathing. Although the pathogenesis of obstructive sleep apnea hypopnea syndrome (OSAHS) was closely associated with GG dysfunction, its causes and possible treatment have not been elucidated. The aim of the study was to investigate the effects of chronic intermittent hypoxia (CIH) on serum adiponectin levels, electromyograph (EMG) activity and ultrastructure of GG, as well as the effect of an adiponectin supplement in anesthetized rats.

METHODSForty-two healthy male Wistar rats were randomly divided into normal control (A), CIH (B) and adiponectin treatment (C) groups, 14 rats in each group. CIH was performed eight hours per day for five weeks in both groups B and C. Group C received transvenous injection of adiponectin at the dosage of 10 microg per injection, twice a week for five weeks. At the end of the 5th week the GG EMG voltage was measured and compared among the three groups. Transmission electron microscope was used to observe the ultrastructure of the GG.

RESULTSCIH caused significant hypoadiponectinemia, weakened activity of GG EMG at both baseline and hypoxia stimulation, and induced ultrastructural pathological changes, such as, myofibril discontinuities, lysis of myofilament, edema of mitochondria and disruption of cristae, vacuolus and lysis of some mitochondria. Venous supplement of adiponectin improved the above pathological changes resulting from CIH.

CONCLUSIONCIH resulted in pathological changes in GG's EMG and ultrastructure, which could be improved by supplement of adiponectin and be associated with hypoadiponectinemia caused by CIH.

Abstract: Objective　To evaluate the potential transmission risk of schistosomiasis in Yunnan Province, and to provide strategic basis for the prevention and control. Methods　Based on the prevalence of schistosomiasis, the social and environmental factors that may lead to the epidemic, 1-3 villages from 3 provincial-level and 15 county-level counties (cities and districts) were selected as the evaluated villages in 2021. The risk of schistosomiasis spread was analyzed comprehensively by consulting, reviewing and collecting routine surveillance data of schistosomiasis in the villages, combined with snail and wild feces survey. The risk level was evaluated for the positive snails, positive wild feces, resident infection, average density of live snails and snail frame occurrence rate. Results　Totally 7 snail counties schistosomiasis transmission was blocked of 18 epidemic counties and the rest were eliminated counties. A total of 152 447 snail frames were investigated and 3 043 frames with snails, 15 895 snails were captured and included 15 727 live snails in the 32 evaluated villages. The total area of snail was 58.87 hm2 and the area of reoccurrence was 34.19 hm2 with snail frame occurrence rate of 2.00% and average density of live snails 0.103 2/0.11 m2, and no positive snails were found by loop-mediated isothermal amplification (LAMP) assay. A total of 1 374 wild feces were collected in 27 evaluated villages of 14 epidemic counties, mainly from cattle, dogs, sheep, equine animals, pigs and so on, all of which were negative. According to the risk assessment of epidemic spread, Yongle Village and Yongsheng Village in Eryuan County, Zhiming Village in Chuxiong City were Ⅱ risk, and the rest were Ⅲ risk. Conclusions　Although the risk of transmission is low in Yunnan Province, the risk of transmission and spread still exists. It is necessary to strengthen the risk monitoring, control of snail and effective management of livestock to prevent the rebound of the epidemic.

OBJECTIVETo investigate the clinical and lab features of sibling brother and sister both with Duchenne muscular dystrophy (DMD).

METHODSWe conducted comprehensive clinical and lab investigations including the test of serum enzymes, electromyography (EMG), electrocardiography, color Doppler echocardiography, HE staining of skeletal muscles, immunohistochemical study of dystrophin and utrophin, multiple ligation probe amplification (MLPA) on exon 1-79 of dystrophin gene, and short tandem repeat-poly- merase chain reaction of CA repeats located in dystrophin gene.

RESULTSThese two patients were confirmed to suffer from DMD. They were characterized by typical features of DMD including typical clinical manifestations, increased serum enzymes, EMG presenting myogenic impairment, HE staining presentation belonging to DMD, negative dystrophin in brother, and inconstantly positive on the sarcolemma of sister. Furthermore, no deletion or duplication was found in the 1-79 exons of dystrophin gene. The suffering brother and sister carried the same maternal X chromosome.

CONCLUSIONSCarriers of DMD gene show typical clinical and laboratory manifestations of DMD. Comprehensive examinations should be performed for such carriers.
