RESUMO

Verdesmummenglaense (C. Chen & X. J. Cui) H. Ohashi & K. Ohashi is a rare species in the tribe Desmodieae (Fabaceae) from Southwest China. The morphological observation shows that the species has minute capitate stigma and ebracteolate calyces, which are entirely different from the funnel-shaped stigma and bracteolate calyces of the genus Verdesmum H. Ohashi & K. Ohashi, but are consistent with those of the genus Hylodesmum H. Ohashi & R. R. Mill. The generic placement of V.menglaense within Hylodesmum was further supported by molecular evidence. Therefore, this species should be returned to Hylodesmum as H.menglaense (C. Chen & X. J. Cui) H. Ohashi & R. R. Mill. A full description including floral characters, a colour plate and a distribution map are first provided here for this species. After excluding the solo representative in China, Verdesmum should be removed from the record in Flora of China.

RESUMO

To advance our knowledge of orchid relationships and timing of their relative divergence, we used 76 protein-coding genes from plastomes (ptCDS) and 38 protein-coding genes from mitochondrial genomes (mtCDS) of 74 orchids representing the five subfamilies and 18 tribes of Orchidaceae, to reconstruct the phylogeny and temporal evolution of the Orchidaceae. In our results, the backbone of orchid tree well supported with both datasets, but there are conflicts between these trees. The phylogenetic positions of two subfamilies (Vanilloideae and Cypripedioideae) are reversed in these two analyses. The phylogenetic positions of several tribes and subtribes, such as Epipogiinae, Gastrodieae, Nerviliinae, and Tropidieae, are well resolved in mtCDS tree. Thaieae have a different position among higher Epidendroideae, instead of sister to the higher Epidendroideae. Interrelationships of several recently radiated tribes within Epidendroideae, including Vandeae, Collabieae, Cymbidieae, Epidendreae, Podochileae, and Vandeae, have good support in the ptCDS tree, but most are not resolved in the mtCDS tree. Conflicts between the two datasets may be attributed to the different substitution rates in these two genomes and heterogeneity of substitution rate of plastome. Molecular dating indicated that the first three subfamilies, Apostasioideae, Cypripedioideae and Vanilloideae, diverged relatively quickly, and then there was a longer period before the last two subfamilies, Orchidoideae and Epidendroideae, began to radiate. Most mycoheterotrophic clades of Orchidaceae evolved in the last 30 million years with the exception of Gastrodieae.

RESUMO

BACKGROUND: Subtribe Orchidinae (Orchidaceae, Orchidoideae) are a nearly cosmopolitan taxon of terrestrial orchids, comprising about 1800 species in 47 to 60 genera. Although much progress has been made in recent years of phylogenetics of Orchidinae, considerable problems remain to be addressed. Based on molecular phylogenetics, we attempt to illustrate the phylogenetic relationships and discuss generic delimitation within Orchidinae. Seven DNA markers (five plastid and two nuclear), a broad sampling of Orchidinae (400 species in 52 genera) and three methods of phylogenetic analysis (maximum likelihood, maximum parsimony and Bayesian inference) were used. RESULTS: Orchidinae s.l. are monophyletic. Satyrium is sister to the rest of Orchidinae s.l. Brachycorythis and Schizochilus are successive sister to Asian-European Orchidinae s.s. Sirindhornia and Shizhenia are successive sister to clade formed by Tsaiorchis-Hemipilia-Ponerorchis alliance. Stenoglottis is sister to the Habenaria-Herminium-Peristylus alliance. Habenaria, currently the largest genus in Orchidinae, is polyphyletic and split into two distant clades: one Asian-Australian and the other African-American-Asian. Diplomeris is sister to Herminium s.l. plus Asian-Australian Habenaria. CONCLUSIONS: We propose to recognize five genera in the Ponerorchis alliance: Hemipilia, Ponerorchis s.l., Sirindhornia, Shizhenia and Tsaiorchis. Splitting Habenaria into two genera based on morphological characters and geographical distribution may be the least disruptive approach, and it is reasonable to keep Satyrium in Orchidinae.

RESUMO

An investigation of a questionable species of the genus Alseodaphne led to the discovery of a new genus Alseodaphnopsis H. W. Li & J. Li, gen. nov., separated from Alseodaphne Nees, and a new species Alseodaphnopsis ximengensis H. W. Li & J. Li, sp. nov., endemic to Yunnan province, China. This new species is characterized by having big, axillary, paniculate inflorescences, as well as large, subglobose fruits. Based on DNA sequence data from two gene regions (nuclear ribosomal ITS and LEAFY intron II), we investigate its phylogenetic position within the Persea group. Phylogenies using maximum parsimony (MP) and Bayesian inference (BI) support the recognition of Alseodaphnopsis as a distinct genus but do not resolve well its relationship within the Persea group. The new genus is circumscribed, eight new combinations for its species are made, and a description and illustration of the new species are provided.

RESUMO

OBJECTIVE: To study the corrosion behavior of magnesium alloy surface treated with micro-arc oxidation and hydrothermal deposition in living animals. METHODS: A magnesium oxide (MgO) layer was prepared on Mg alloy using micro-arc oxidation technology, and then a composite coating composed of magnesium hydroxide, hydroxyapatite, and MgO was coated on the MgO layer using the hydrothermal deposition method for 2 h and 24 h. Male 3-month-old white New Zealand rabbits (n = 48) weighting 2200-2300 g, were divided into four groups randomly. The prepared Mg alloy samples with composite coatings were implanted into the femoral medullary cavity of rabbits. For the Mg group, bare Mg samples without any treatment were implanted; for the MgO group, bare Mg samples undergoing MAO treatment were implanted; for the HT2h group, samples of the MgO group undergoing hydrothermal treatment (HT) for 2 h were implanted; and for the HT24h group, samples of group MgO undergoing HT for 24 h were implanted. Then the in vivo corrosion behaviors of implants were evaluated by X-ray observation, micro-CT analysis and serum Mg2+ examination. RESULTS: The X-ray showed that samples implanted in animals were decreased as time went by. The micro-CT showed that on the fourth week, the residual volume percentages (RVP) of samples of the Mg, MgO, HT2h, and HT24h groups were 72.81% ± 2.10%, 71.68% ± 1.49%, 81.14% ± 1.54%, and 82.04% ± 0.89%, respectively; on the eighth week, the RVP of four groups were 29.45% ± 1.06%, 41.82% ± 1.13%, 53.92% ± 0.37%, and 62.53% ± 2.06%, respectively; while on the 12th week, RVP were 8.45% ± 0.49%, 9.97% ± 0.75%, 37.09% ± 0.89%, 46.71% ± 1.87%. The RVP of the HT2h group and the HT24h group were higher than for the Mg group and the MgO group for all three time points (P < 0.05); the RVP for HT24h was higher than for HT2h at 8 and 12 weeks, and the differences were significant, indicating that the degradation of Mg alloy slowed down after composite coating. In addition, the composite-coated Mg alloy by 24-h hydrothermal treatment exhibited a slower degradation than that treated by 2 h. Serum Mg2+ concentration results showed that on the second week, the Mg2+ concentrations of the Mg, MgO, HT2h, and HT24h groups were 2.24 ± 0.10 mmol/L, 2.12 ± 0.07 mmol/L, 2.06 ± 0.11 mmol/L, and 2.15 ± 0.12 mmol/L, respectively. On the fourth week, these concentrations were 1.99 ± 0.33 mmol/L, 2.18 ± 0.06 mmol/L, 2.17 ± 0.09 mmol/L, and 2.13 ± 0.14 mmol/L, respectively. On the eighth week, the concentrations were 2.22 ± 0.09 mmol/L, 2.20 ± 0.17 mmol/L, 2.06 ± 0.11 mmol/L, and 2.14 ± 0.07 mmol/L, respectively. On the 12th week, the concentrations were 2.18 ± 0.04 mmol/L, 2.20 ± 0.08 mmol/L, 2.09 ± 0.02 mmol/L, and 2.16 ± 0.11 mmol/L. CONCLUSION: The combination of micro-arc oxidation and hydrothermal deposition can greatly improve the anti-corrosion behavior of Mg alloy, and Mg alloy coated with this composite coating is a promising biomaterial with a satisfactory degradation rate.

RESUMO

The plastid genome (plastome) of heterotrophic plants like mycoheterotrophs and parasites shows massive gene losses in consequence to the relaxation of functional constraints on photosynthesis. To understand the patterns of this convergent plastome reduction syndrome in heterotrophic plants, we studied 12 closely related orchids of three different lifeforms from the tribe Neottieae (Orchidaceae). We employ a comparative genomics approach to examine structural and selectional changes in plastomes within Neottieae. Both leafy and leafless heterotrophic species have functionally reduced plastid genome. Our analyses show that genes for the NAD(P)H dehydrogenase complex, the photosystems, and the RNA polymerase have been lost functionally multiple times independently. The physical reduction proceeds in a highly lineage-specific manner, accompanied by structural reconfigurations such as inversions or modifications of the large inverted repeats. Despite significant but minor selectional changes, all retained genes continue to evolve under purifying selection. All leafless Neottia species, including both visibly green and nongreen members, are fully mycoheterotrophic, likely evolved from leafy and partially mycoheterotrophic species. The plastomes of Neottieae span many stages of plastome degradation, including the longest plastome of a mycoheterotroph, providing invaluable insights into the mechanisms of plastome evolution along the transition from autotrophy to full mycoheterotrophy.

RESUMO

BACKGROUND: Previous studies have shown that electroacupuncture (EA) has a significant effect on acute pain, but it has not solved the clinical problem of the chronification of acute pain. Diffuse noxious inhibitory controls (DNIC) function as a reliable indicator to predict the risk of chronic pain events. DNIC function in knee osteoarthritis (KOA) patients has been demonstrated to gradually decrease during the development of chronic pain. The purpose of this study is to conduct a randomized, controlled clinical trial to determine if EA can repair impaired DNIC function and thus prevent chronification of the acute pain of KOA. METHODS/DESIGN: This is a multicenter, single blind, randomized, controlled, three-arm, large-scale clinical trial. A total of 450 KOA patients will be randomly assigned to three groups. The strong EA group will receive EA with high-intensity current (2 mA < current < 5 mA) at the ipsilateral 'Neixiyan' (EX-LE5), 'Dubi'(ST35), 'Liangqiu'(ST34) and 'Xuehai' (SP10). The weak EA group will receive EA with low-intensity current (0 mA < current < 0.5 mA) on the same acupoints. The sham EA group will receive EA with low-intensity current (0 mA < current < 0.5 mA) with fine needles inserted superficially into the sites 2 cm lateral to the above acupoints. The patients will be treated with EA once a day, 30 minutes per session, in 5 sessions per week, for 2 weeks. In order to determine the best stage of KOA for effective EA intervention, patients within the treatment groups also will be divided into four stages. The primary outcomes are Visual Analog Scale (VAS), DNIC function and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Clinical assessments will be evaluated at baseline (before treatment) and after 5 to 10 sessions of treatment. DISCUSSION: This trial will be helpful in identifying whether strong EA is more effective than weak EA in reversing chronification of acute pain through repairing the impaired DNIC function and in screening for the best stage of KOA for effective EA intervention. TRIAL REGISTRATION: Chinese Clinical Trial Registry Number: ChiCTR-ICR-14005411. The date of registration is 31 October 2014.

RESUMO

The subtribe Orchidinae, distributed predominantly in Eastern Asia and the Mediterranean, presents some of the most intricate taxonomic problems in the family Orchidaceae with respect to generic delimitation. Based on three DNA markers (plastid matK, rbcL, and nuclear ITS), morphological characters, and a broad sampling of Orchidinae and selected Habenariinae mainly from Asia (a total of 153 accessions of 145 species in 31 genera), generic delimitation and phylogenetic relationships within the subtribe Orchidinae and Habenariinae from Asia were assessed. Orchidinae and Asian Habenariinae are monophyletic, and Orchidinae is divided into distinct superclades. Many genera, such as Amitostigma, Habenaria, Hemipilia, Herminium, Platanthera, Peristylus and Ponerorchis, are not monophyletic. Habenaria is subdivided into two distantly related groups, while Platanthera is subdivided into three even more disparate groups. Many previously undetected phylogenetic relationships, such as clades formed by the Amitostigma-Neottianthe-Ponerorchis complex, Platanthera latilabris group, Ponerorchis chrysea, Sirindhornia, and Tsaiorchis, are well supported by both molecular and morphological evidence. We propose to combine Hemipiliopsis with Hemipilia, Amitostigma and Neottianthe with Ponerorchis, Smithorchis with Platanthera, and Aceratorchis and Neolindleya with Galearis, and to establish a new genus to accommodate Ponerorchis chrysea. Tsaiorchis and Sirindhornia are two distinctive genera supported by both molecular data and morphological characters. A new genus, Hsenhsua, and 41 new combinations are proposed based on these findings.

RESUMO

Collabieae (Orchidaceae) is a long neglected tribe with confusing tribal and generic delimitation and little-understood phylogenetic relationships. Using plastid matK, psaB, rbcL, and trnH-psbA DNA sequences and morphological evidence, the phylogenetic relationships within the tribe Collabieae were assessed as a basis for revising their tribal and generic delimitation. Collabieae (including the previously misplaced mycoheterotrophic Risleya) is supported as monophyletic and nested within a superclade that also includes Epidendreae, Podochileae, Cymbidieae and Vandeae. Risleya is nested in Collabiinae and sister to Chrysoglossum, a relationship which, despite their great vegetative differences, is supported by floral characters. Ania is a distinct genus supported by both morphological and molecular evidence, while redefined Tainia includes Nephelaphyllum and Mischobulbum. Calanthe is paraphyletic and consists four clades; the genera Gastrorchis, Phaius and Cephalantheropsis should be subsumed within Calanthe. Calanthe sect. Ghiesbreghtia is nested within sect. Calanthe, to which the disputed Calanthe delavayi belongs as well. Our results indicate that, in Collabieae, habit evolved from being epiphytic to terrestrial.

RESUMO

Dendrobium is one of the three largest genera and presents some of the most intricate taxonomic problems in the family Orchidaceae. Based on five DNA markers and a broad sampling of Dendrobium and its relatives from mainland Asia (109 species), our results indicate that mainland Asia Dendrobium is divided into eight clades (with two unplaced species) that form polytomies along the spine of the cladogram. Both Dendrobium and Epigeneium are well supported as monophyletic, whereas sect. Dendrobium, sect. Densiflora, sect. Breviflores, sect. Holochrysa, are paraphyletic/polyphyletic. Many ignored phylogenetic relationships, such as the one of major clades formed by D. jenkinsii and D. lindleyi (two members of sect. Densiflora), the Aphyllum group, the Devonianum group, the Catenatum group, the Crepidatum group, and the Dendrobium moniliforme complex are well supported by both molecular and morphological evidence. Based on our data, we propose to broaden sect. Dendrobium to include sect. Stuposa, sect. Breviflores, and sect. Holochrysa and to establish a new section to accommodate D. jenkinsii and D. lindleyi. Our results indicated that it is preferable to use a broad generic concept of Dendrobium and to pursue an improved infrageneric classification at sectional level, taking into account both morphology and current molecular findings.

RESUMO

OBJECTIVE: To compare the therapeutic effects of different types of acupuncture therapy on herpes zoster (acute stage). METHODS: A total of 189 cases of acute herpes zoster outpatients and inpatients were recruited in the present multicenters (3 hospitals) randomized controlled clinical trials. They were divided into (computer-aided random allocation): basic acupuncture (n = 36), cotton moxibustion (n = 35), fire needle (n = 43), tapping-cupping (n = 39) and medication (n = 36) groups. Ashi-points (around the locus), Jiaji (EX-B 2), Zhigou (SJ 6) and Houxi (SI 3) were used in this study. For patients of the acupuncture group, the abovementioned acupoints were punctured with filiform needles (encircled needling around the affected loci) and also stimulated with electroacupuncture (EA). For patients of the cotton moxibustion group, thin defated dry cotton pieces put over the Ashi-point were ignited, 3 times altogether, followed by EA and encircled needling stimulation which were the same to those in the basic acupuncture group. Patients of the fire needle group were treated by pricking the herpes (3-5 in number) with a hot-red needle, followed by EA and encircled needling treatment. Patients of the tapping-cupping group were treated by tapping Ashi-points repeatedly with a percussopunctator and cupping over the pricked region, followed by EA and encircled needling treatment. Patients of the medication group were treated by oral administration of Valaciclovir Hydrochlordide (300 mg/time, twice a day) and vitamin B1 (10 mg/time, t. i.d.) for 10 days. The acupuncture-moxibustion treatment was given once daily for 10 days. The time of blister-occurrence cease, scab formation and decrustation was recorded, and pain degree was evaluated using visual analog scale (VAS). The therapeutic effect was assessed according to the related standards. RESULTS: There were no significant differences among the 5 groups in the time of blister-occurrence cease, scab formation and decrustation, and in the therapeutic effect (P > 0.05). The VAS scores of the 5 groups were decreased gradually and apparently along with the treatment (P < 0.05), suggesting a pain relief after the treatment. In comparison with the medication group, the VAS scores of the basic acupuncture group, cotton moxibustion group, fire needle group and tapping-cupping group were significantly lower from the 7th day on following the treatment (P < 0.05). CONCLUSION: Acupuncture plus encircled needling and acupuncture plus encircled needling combined with cotton-moxibustion, or with fire needle stimulation, or with tapping and cupping are effective in the treatment of herpes zoster at the acute stage, being comparable to the medication in the clinical curative effect and improvement of blisters, and better than medication in pain relief.

RESUMO

To identify genes induced during Pseudoperonospora cubensis (Berk. and Curk.) Rostov. infection in cucumber (Cucumis sativus L.), the suppression subtractive hybridization (SSH) was performed using mixed cDNAs prepared from cucumber seedlings inoculated with the pathogen as a tester and cDNA from uninfected cucumber seedlings as a driver. A forward subtractive cDNA library (FSL) and a reverse subtractive cDNA library (RSL) were constructed, from which 1,416 and 1,128 recombinant clones were isolated, respectively. Differential screening of the preferentially expressed recombinant clones identified 58 unique expressed sequence tags (ESTs) from FSL and 29 from RSL. The ESTs with significant protein homology were sorted into 13 functional categories involved in nearly the whole process of plant defense such as signal transduction and cell defense, transcription, cell cycle and DNA processing, protein synthesis, protein fate, proteins with binding functions, transport, metabolism and energy. The expressions of twenty-five ESTs by real-time quantitative RT-PCR confirmed that differential gene regulation occurred during P. cubensis infection and inferred that higher and earlier expression of transcription factors and signal transduction associated genes together with ubiquitin/proteasome and polyamine biosynthesis pathways may contribute to the defense response of cucumber to P. cubensis infection. The transcription profiling of selected down-regulated genes revealed that suppression of the genes in reactive oxygen species scavenging system and photosynthesis pathway may inhibit disease development in the host tissue.

RESUMO

AIM: To determine the clinical characteristics of vulvovaginal candidiasis (VVC), the Candida species involved and the antifungal susceptibility of Candida species isolated from patients with VVC. METHODS: Candida organisms were cultured from samples obtained from patients who presented with VVC to the Gynecology Department, Peking University Shenzhen Hospital. Antifungal susceptibility testing was performed using a commercial agar diffusion test. RESULTS: Of the 1,070 cases of VVC reported in this study, 36.5% were uncomplicated VVC, and 63.5% were complicated VVC. Twenty-four patients were identified as having two species of Candida. Candid albicans alone was isolated from 89.5% of cases (n = 958). Candida glabrata was isolated from 85 cases (7.9%), Candida tropicalis from 10 (0.9%), Saccharomyces cerevisiae from eight (0.7%), Candida parapsilosis from six (0.6%), Candida famata from two (0.2%), and Candida krusei from one case (0.1%). All isolates of Candida albicans were susceptible to nystatin. The resistant rate of Candida albicans to azole agents was 0-4.9%. CONCLUSION: Candida albicans was the predominant Candida species isolated from this series of patients with VVC. Resistance of vaginal Candida albicans isolates to antifungal agents was infrequent.

RESUMO

OBJECTIVE: To observe clinical therapeutic effect of monkshood cake-separated mild-warm moxibustion at Zusanli (ST 36) and Xiyan (EX-LE 5) on knee osteoarthritis. METHODS: The patients of monkshood cake-separated mild-warm moxibustion group were treated with monkshood cake-separated mild-warm moxibustion at Dubi (ST 35), Zusanli (ST 36) and Neixiyan (EX-LE 4) on the affected side, and the medication group with oral administration of Xianling Gubao Capsules. After treatment for 4 weeks, VAS and index of severity of osteoarthritis (ISOA scale) were used for assessment of clinical therapeutic effect. RESULTS: After treatment, the arthralgia and the index of severity significantly improved in the two groups (P < 0.01), and the analgesic effect and improvement of ISOA in the monkshood cake-separated mild-warm moxibustion group were better than those in the medication group (P < 0.05). The basic clinical cured rate was 80.0% and the effect-producing time was (10.91 +/- 4.17) days in the monkshood cake-separated mild-warm moxibustion group, and 53.3% and (12.28 +/- 4.60) days in the medication group, respectively, with a significant difference between the two groups (P < 0.05). CONCLUSION: Therapeutic effect of monkshood cake-separated mild-warm moxibustion on knee osteoarthritis is better than that of oral administration of Xianling Gubao Capsules.

RESUMO

OBJECTIVE: To observe the effect-increasing action of cake-separated mild moxibustion on rheumatoid arthritis (RA), and to probe a new method for RA. METHODS: Sixty cases were randomly divided into 2 groups. The control group (n=30) were treated with oral administration of methotrexate (MTX) as basic treatment, and non-steroid anti-inflammatory agents (NSAIDs) according to conditions of the patient. The treatment group (n=30) were treated with the same treatment as the control group, and Fuzi case-separated moxibustion at Guanyuan (CV 4) and Zusanli (ST 36) was added. They were treated for 3 months. RESULTS: After treatment of 3 months, the total effective rate was 83.3% in the treatment group, which was higher than 60.0% in the control group (P < 0.05); there were significant differences before and after treatment in all indexes in the two groups (P < 0.05 or P < 0.01); the ratio of the patients who completely withdrew NSAIDs in the treatment group was significantly higher than that in the control group (P < 0.05); the rate of adverse reaction in the treatment group was significantly lower than that in the control group (P < 0.05). CONCLUSION: Fuzi cake-separated mild moxibustion can increase clinical therapeutic effect on RA and reduce dosage of NSAIDs.

RESUMO

OBJECTIVE: To determine the clinical manifestations of vulvovaginal candidiasis (VVC) and to study the mycologic eradication rate of different miconazole treatment courses for VVC. METHODS: Three hundred cases of VVC were recruited. The Candidas were cultured. A prospective and randomized study was performed to compare the treatment effect of 3 day miconazole (400 mg/d), 6 day miconazole (400 mg/d), and 7 day miconazole (200 mg/d) for uncomplicated and complicated VVC. RESULTS: Among 300 cases of VVC, uncomplicated, complicated and recurrent VVC were 56.0%, 44.0% and 9.7% (29/300) respectively. C. albicans was isolated most frequently 90.3% (271/300), followed by C. glabrata (7.3%), C. tropicalis (1.3%), C. krusei (0.7%), and C. parapsilosis (0.3 %). Mycologic eradication rate of 3 day, 6 day and 7 day miconazole courses for uncomplicated VVC at day 14 was 96.0%, 93.5% and 98.0%, respectively (P > 0.05). Eradication rate of 3 day, 6 day and 7 day miconazole courses for complicated VVC at day 14 was 86.7%, 92.5%, and 86.4%, respectively (P > 0.05). Eradication rate of 3 day, 6 day and 7 day miconazole courses for uncomplicated VVC at day 35 was 93.8%, 95.3%, and 89.8%, respectively (P > 0.05). Eradication rate of 3 day, 6 day and 7 day miconazole courses for complicated VVC at day 35 was 89.7%, 97.3% and 86.8%, respectively (P > 0.05). CONCLUSION: Treatment of VVC should be individualized, and women with complicated VVC achieve superior mycologic eradication by a 6 day miconazole course.
