[Adverse events/adverse reactions of acupoint catgut embedding therapy for psoriasis vulgaris: a systematic review].

OBJECTIVE: To systematically review the occurrence of adverse events/adverse reactions (AEs/ARs) induced by acupoint catgut embedding therapy for psoriasis vulgaris (PV) and its safety. METHODS: Randomized controlled trials, controlled clinical trials, cohort studies, case-control studies, case-series, and case reports concerning the treatment of PV with acupoint catgut embedding therapy were searched from Chinese and English databases from their inception to January 7th, 2021. The AEs/ARs related to acupoint catgut embedding therapy for PV were subjected to descriptive statistics, followed by the analysis of possible reasons. RESULTS: Finally, 16 studies were included, involving 1 158 patients. A total of 79 cases were reported to present with mild to moderate AEs/ARs related to acupoint catgut embedding therapy for PV, and there were no serious AEs/ARs or death cases. The most common AEs/ARs were local redness, swelling, heat, and pain (31.65%,25/79), followed by low-grade fever and fatigue (29.11%,23/79), isomorphic reaction (16.46%,13/79), local induration (13.92%,11/79), and fainting (8.86%,7/79). In terms of embedding materials, catgut (93.67%,74/79) and lumbar puncture needles or other puncture needles (49.37%,39/79) were proved the most common AEs/ARs-inducing factors. The proportion of AEs/ARs resulting from treatment interval≤two weeks (67.09%,53/79) and treatment course≤eight weeks (55.70%,44/79) was relatively high. Because the incidence of AEs/ARs fails to be calcula-ted, it is not yet possible to accurately assess the risk and safety of acupoint catgut embedding therapy for PV. CONCLUSION: Available evidence suggests that in the treatment of PV, acupoint catgut embedding therapy may induce a series of mild to moderate AEs/ARs, so its clinical practice deserves attention. We should strictly grasp its indications and contraindications, and prevent the occurrence of related AEs/ARs by standardizing the operation and improving the embedding materials.

Comparison of PSORI-CM01 granules and Yinxieling tablets for patients with chronic plaque psoriasis: a pilot study for a randomized, double-blinded, double-dummy, multicentre trial.

BACKGROUND: To compare the efficacy and safety of PSORI-CM01 granules with Yinxieling tablets in patients with chronic plaque psoriasis (CPP), we plan to conduct a multicentre, randomized, double-blinded, double-dummy, controlled trial. This pilot study was conducted to determine the feasibility and the potential of the protocol for the full-scale randomized controlled trial (RCT). METHODS: This pilot study was conducted in three centers, and compared PSORI-CM01 granules with Yinxieling tablets in patients with CPP during a 12-week treatment and 3-month follow-up period. The primary efficacy endpoint was the decrease of the psoriasis area severity index (PASI) at week 12. The secondary outcome measures included reduction rates of PASI, pruritus scores on the Visual Analogue Scale (VAS), body surface area (BSA), and the Dermatology Life Quality Index (DLQI). Safety was assessed via the incidence of adverse events (AEs) in each treatment group. RESULTS: A total of 211 patients were screened, and 63 subjects who met the inclusion criteria were randomised to PSORI-CM01 granule group (N=31) or Yinxieling tablets group (N=32) while 39 subjects finished the study. The primary outcome measure showed a mean decrease of PASI of 2.03 in the PSORICM01 group compared to 0.89 in the Yinxieling group at week 12. Except for the VAS score (t=-2.261, P=0.027), the secondary outcomes showed no significant improvement from baseline in both groups at week 12. No safety or tolerability concerns related to the drugs were observed in either group. CONCLUSIONS: This pilot study showed that the RCT is feasible for randomization, patient recruitment, and assessment. Major strategies are necessary to reduce the patient dropout rate before conducting the full RCT. In this pilot study, the PSORI-CM01 granule exhibited greater potential for development compared to its original formula (Yinxieling tablets) for the treatment of CPP.

Add-on effect of PSORI-CM01 to topical calcipotriol for moderate psoriasis vulgaris: A multi-center, randomized, double-blind pilot study.

BACKGROUND: Mild-moderate psoriasis vulgaris is a common dermatological autoimmune condition with limited conventional therapeutic options. Safe and effective adjunct therapies to topical non-steroidal antipsoriatic therapy are needed. The oral Chinese herbal medicine (CHM) formula PSORI-CM01 has been evidenced potential antipsoriatic pharmacological activity. This article reports a pilot study which was designed as a double-blinded, placebo-controlled randomized controlled trial (RCT) evaluating the effects of PSORI-CM01 when added to topical calcipotriol cream. METHODS: People with moderate psoriasis vulgaris were randomized to receive oral PSORI-CM01 or placebo administered for 12 weeks in combination with calcipotriol. The primary clinical outcome was the change of psoriasis area severity index (PASI) score at week 12 and week 24. Secondary clinical outcomes were PASI75, PASI50, relapse rate, change in body surface area, dermatology life quality index and Skindex29, and adverse events (AEs). Participants' satisfaction and willingness to repeat were also assessed. RESULTS: The pilot study was conducted in Australia and China, 29 participants were randomized with 26 completed the treatment and follow-up. Participants' baseline basic characteristics were comparable. No between-group statistical significance was found on pre-defined clinical outcome measures, although there seemed a trend of treatment effects favoring the combination of PSORI-CM01 with calcipotriol. Frequency and severity of AEs were similar between two groups, with no severe AEs reported. CONCLUSIONS: The design and duration of the study appears feasible. A proper powered RCT with slight adjustments in the methods is needed to reveal the add-on effects of oral CHM PSORI-CM01. The experience and results from this pilot study will contribute to the refine of objectives and design of a future study, and assist the sample size calculation for the full-scale RCT.

The Gene Expression Analysis of Peripheral Blood Monocytes From Psoriasis Vulgaris Patients With Different Traditional Chinese Medicine Syndromes.

Psoriasis is chronic skin disease and an important health concern. Traditional Chinese Medicine (TCM) has shown great promise in the treatment of psoriasis. However, the correlation between TCM Syndromes and genomics of psoriasis has not been evaluated. Here, we analyzed gene expression profiling of monocytes from psoriasis vulgaris patients with different TCM syndrome types to reveal the molecular basis of different psoriasis syndromes. Of the 62 cases of psoriasis vulgaris recruited, 16, 23, and 23 cases were of blood-heat syndrome, blood stasis syndrome, and blood-dryness syndrome, respectively; 10 healthy controls were recruited as controls. Affymertix's Gene Chip ®clariom D gene chip was used to detect the gene expression profile of peripheral blood monocytes collected from recruited individuals. Compared with the healthy control group, 1570 genes were up-regulated and 977 genes were down-regulated in the psoriasis vulgaris patients group; 798 genes and 108 genes were up- and down-regulated in the blood-heat syndrome group respectively; 319 and 433 genes were up- and down-regulated in the blood-dryness syndrome group, respectively; and 502 and 179 genes were up-and down-regulated in the blood-stasis syndrome group. Our analyses indicated not only common differential genes and pathways between psoriasis syndrome groups and healthy controls, but also syndrome-specific genes and pathways. The results of this study link the three syndromes at the gene level and will be useful for clarifying the molecular basis of TCM syndromes of psoriasis.

Metabonomics Study on Serum Characteristic Metabolites of Psoriasis Vulgaris Patients With Blood-Stasis Syndrome.

Psoriasis is a chronic, refractory, systemic inflammatory skin disease. Traditional Chinese medicine (TCM) shows unique advantage in the treatment of psoriasis based on syndrome differentiation. An untargeted high-throughput metabonomics method based on liquid chromatography coupled to mass spectrometry was applied to study the serum metabolic characteristics in different TCM syndrome types in patients with psoriasis vulgaris (PV), and to discover potential serum biomarkers for its pathogenesis on the endogenous metabolite differentiation basis. The serum metabolic profiles of 45 healthy controls and 124 patients with PV (50 in the blood-stasis group, 30 in the blood-heat group, and 44 in the blood-dryness group) were acquired. The raw spectrometric data were processed using multivariate statistical analysis, and 14 biomarkers related to TCM syndrome differentiation and psoriasis types were screened and identified. The blood-stasis syndrome group showed abnormal lipid metabolism, which was characterized by a low level of phosphatidylcholine (PC) and a high level of lysophosphatidylcholine (LPC). We propose that platelet-activating factor can be applied as a potential biomarker in clinical diagnosis and differentiation of PV with blood-stasis syndrome. The difference in the serum metabolites among PV types with different TCM syndromes and healthy control group illustrated the objective material basis in TCM syndrome differentiation and classification of psoriasis.

Analysis of microRNA expression in peripheral blood monocytes of three Traditional Chinese Medicine (TCM) syndrome types in psoriasis patients.

BACKGROUND: To analyze the expression of miRNA (microRNA) in peripheral blood mononuclear cells in patients with Psoriasis vulgaris with different TCM syndromes by miRNA chip. It further revealed the micromaterial basis of different syndrome types of psoriasis at the miRNA level. METHODS: Peripheral blood monocytes were collected and prepared from 30 patients with Psoriasis vulgaris (including 9 patients of blood heat syndrome, 8 patients of blood stasis syndrome, and 13 patients of blood dry syndrome) and 9 healthy controls. The miRNA expression profile of peripheral blood monocytes was detected by Agilent Hum miRNA chip. RESULTS: Compared to the healthy control group, 156 upregulated and 242 downregulated miRNAs were detected in all psoriasis patients. Compared to the healthy control group, 40 miRNAs were upregulated and 44 were downregulated in the blood heat syndrome group. Furthermore, there were 49 upregulated miRNAs and 44 downregulated miRNAs in the dry syndrome group as compared to the healthy control group. Also, 67 miRNAs were upregulated and 154 miRNAs were downregulated in the blood stasis syndrome group as compared to the healthy control group. CONCLUSIONS: There are common different miRNAs and pathways, as well as specific miRNAs between the psoriasis and the healthy control groups.Trial registration ChiCTR-TRC-14005185 registered on August 8, 2014.

Auricular acupressure as a complementary therapy for psoriasis vulgaris: study protocol for a multicenter randomized controlled trial.

INTRODUCTION: Psoriasis vulgaris is a common skin disease characterized by persistent localized erythematous scaly plaques, typically on the elbows, knees, and scalp. It is an immune-abnormal disease that progresses slowly over a long period with frequent symptom recurrence. Current studies have shown that acupuncture is an effective therapy for psoriasis. However, the scientific evidence of the efficacy of auricular acupressure treatment for patients with psoriasis is still insufficient. Therefore, we designed a randomized controlled clinical trial to investigate the effect, safety, and cost-effectiveness of auricular acupressure in addition to medication in patients with psoriasis. METHODS AND ANALYSIS: This on-going study is a two-arm parallel, assessor-blinded, randomized controlled trial in which 180 participants with psoriasis will be recruited and then randomly allocated into two groups in a 1:1 ratio. Equal randomization will be conducted using a computer-generated random allocation sequence. Participants in the intervention group will receive auricular acupressure treatment once per week for 4 weeks, and calcipotriol betamethasone ointment for topical use once daily for 4 weeks. Participants in the control group will receive only calcipotriol betamethasone ointment treatment once daily for 4 weeks. All patients will be followed up for 12 weeks. The primary outcome is relapse rate. The secondary outcomes include time to relapse, rebound rate, time to new onset, Psoriasis Area and Severity Index score improvement rate, body surface area affected, a visual analogue scale, and Dermatology Life Quality Index. Cost-effectiveness analysis will be carried out from a health and community care provider perspective. DISCUSSION: This multicenter randomized controlled trial will provide important clinical evidence for the effect and safety of auricular acupressure as a complementary therapy in patients with psoriasis.

In-depth serum proteomics reveals biomarkers of psoriasis severity and response to traditional Chinese medicine.

Serum and plasma contain abundant biological information that reflect the body's physiological and pathological conditions and are therefore a valuable sample type for disease biomarkers. However, comprehensive profiling of the serological proteome is challenging due to the wide range of protein concentrations in serum. Methods: To address this challenge, we developed a novel in-depth serum proteomics platform capable of analyzing the serum proteome across ~10 orders or magnitude by combining data obtained from Data Independent Acquisition Mass Spectrometry (DIA-MS) and customizable antibody microarrays. Results: Using psoriasis as a proof-of-concept disease model, we screened 50 serum proteomes from healthy controls and psoriasis patients before and after treatment with traditional Chinese medicine (YinXieLing) on our in-depth serum proteomics platform. We identified 106 differentially-expressed proteins in psoriasis patients involved in psoriasis-relevant biological processes, such as blood coagulation, inflammation, apoptosis and angiogenesis signaling pathways. In addition, unbiased clustering and principle component analysis revealed 58 proteins discriminating healthy volunteers from psoriasis patients and 12 proteins distinguishing responders from non-responders to YinXieLing. To further demonstrate the clinical utility of our platform, we performed correlation analyses between serum proteomes and psoriasis activity and found a positive association between the psoriasis area and severity index (PASI) score with three serum proteins (PI3, CCL22, IL-12B). Conclusion: Taken together, these results demonstrate the clinical utility of our in-depth serum proteomics platform to identify specific diagnostic and predictive biomarkers of psoriasis and other immune-mediated diseases.

Oral Chinese herbal medicine for psoriasis vulgaris: protocol for a randomised, double-blind, double-dummy, multicentre clinical trial.

INTRODUCTION: Psoriasis vulgaris is a common skin disease that is characterised by persistent localised erythematous scaly plaques. Yinxieling is a Chinese herbal formula for psoriasis that has been used for more than 20 years in China. To facilitate application, PSORI-CM01 was developed based on the optimisation and simplification of Yinxieling tablets performed in a previous study and in clinical practice. However, the scientific evidence regarding whether PSORI-CM01 is more effective for psoriasis than the original Yinxieling remains insufficient. Therefore, we designed a randomised clinical trial to investigate the effect, safety and cost-effectiveness of PSORI-CM01 granules compared with those of Yinxieling tablets for the treatment of patients with psoriasis. METHODS AND ANALYSIS: This ongoing study is a two-arm parallel, randomised, double-blind, double-dummy clinical trial. Five hundred and fifty-six participants with psoriasis will be recruited and then randomly allocated into two groups in a 1:1 ratio. Participants in PSORI-CM01 group will receive a 5.5 g granule of PSORI-CM01 two times daily and five placebo tablets three times daily for 12 weeks. The participants in the Yinxieling group will receive five Yinxieling tablets three times daily and a placebo granule two times daily for 12 weeks. The primary outcome is the reduction of the Psoriasis Area and Severity Index. The secondary outcomes include relapse rate, Visual Analogue Scale scores, body surface area and the Dermatology Life Quality Index. Cost-effectiveness analysis will be performed from a health and community care provider perspective. ETHICS AND DISSEMINATION: This research protocol had been reviewed and approved by the institutional review boards of three trial centres (Guangdong Provincial Hospital of Chinese Medicine (B2014-026-01), Affiliated Hospital of Tianjin Chinese Medicine Academy (2014-KY-001) and Third Hospital of Hangzhou (B2014-026-01)). The findings will be disseminated to the public through conference presentations and open-access journals.

Terms referring to psoriasis vulgaris in the classical Chinese medicine literature: a systematic analysis.

BACKGROUND: Psoriasis vulgaris is a modern medical term. In the classical Chinese medicine (CM) literature, this disorder could be classified under a diversity of terms. In order to explore how psoriasis vulgaris was conceptualized and managed throughout Chinese medical history, we undertook a systematic longitudinal analysis of descriptions in the classical CM literature of skin disorders consistent with psoriasis vulgaris. METHODS: Candidate search terms were identified from 33 contemporary CM books as relevant to psoriasis vulgaris. Thirteen terms were used to search the Zhong Hua Yi Dian--'Encyclopaedia of Traditional Chinese Medicine', 4th edition, a digital collection of over 1000 medical books. Search results were entered in a spreadsheet, citations that were consistent with psoriasis vulgaris were identified based on: (i) a description of the features of psoriasis vulgaris and (ii) judgment by two clinicians regarding relevance to psoriasis vulgaris. Analysis focused on the use of terms by historical period (Chinese dynasty) and whether the terms were specific for psoriasis vulgaris RESULTS: 608 citations dating from 363 to 1947AD were included. The two criteria for determining inclusion of citations were combined to select the pool of citations most relevant to psoriasis vulgaris. Sixty citations from eight search terms were found in this pool. Among the eight terms, Bai Bi, She Shi and Bi Feng consistently identified citations that were likely to be psoriasis. The earliest was from 1368AD (Ming dynasty). The remaining five terms yielded inconsistent results. Citations of disorders consistent with psoriasis vulgaris appear prior to 1368-1644AD (Ming dynasty), but the terms used were not specific for psoriasis. CONCLUSIONS: Bai Bi, She Shi and Bi Feng are the terms most consistently used to refer to psoriasis vulgaris. They first appeared in 1368-1644AD (Ming dynasty) and Bai bi remains in use. Regarding the other terms, certain citations may have referred to psoriasis vulgaris, but in other cases these terms could be used for disorders whose descriptions were inconsistent with psoriasis.

Oral PSORI-CM01, a Chinese herbal formula, plus topical sequential therapy for moderate-to-severe psoriasis vulgaris: pilot study for a double-blind, randomized, placebo-controlled trial.

BACKGROUND: To provide evidence that the Chinese herbal medicine (CHM) PSORI-CM01 combined with Western medicine reduces the relapse rate of psoriasis vulgaris (PV), we plan to conduct a large-scale randomized control trial (RCT). In order to improve and perfect the RCT, this pilot study was designed to determine the feasibility and the potential of a modified protocol for the full-scale RCT. METHODS: Eligible patients with psoriasis vulgaris (PV) were enrolled into a randomized comparison in which all subjects received topical sequential therapy and PSORI-CM01 or placebo for 12 weeks. The primary outcome measure was the relapse rate. Treatment response was computed from Psoriasis Area and Severity Index (PASI), body surface area (BSA), and Dermatology Life Quality Index (DLQI). The secondary outcome measures included time to relapse, time to onset, rebound rate, PASI score, pruritus scores on the Visual Analog Scale (VAS), BSA, DLQI and SF-36 (short form health survey), and incidence of serious adverse events (SAEs). RESULTS: Six of 7 (86 %) subjects reached the PASI-50 in the CHM group compared with nine of 10 (90 %) in the placebo group during the treatment period. Among the subjects who reached PASI-50, one out of six subjects (17 %) relapsed in the CHM group during the treatment period compared with six out of nine patients in the placebo group (67 %). No subjects met the rebound criteria. Changes to baseline in the PASI scores were not significantly different between the two groups (t = 1.764, P = 0.098). CONCLUSION: Oral PSORI-CM01 combined with topical sequential treatment showed a smaller recurrence rate (P = 0.118) than placebo combined with the same topical therapy for moderate-to-severe PV in this pilot study.

Chinese medicine combined with calcipotriol betamethasone and calcipotriol ointment for Psoriasis vulgaris (CMCBCOP): study protocol for a randomized controlled trial.

BACKGROUND: Psoriasis causes worldwide concern because of its high-prevalence, as well as its harmful, and incurable characteristics. Topical therapy is a conventional treatment for psoriasis vulgaris. Chinese medicine (CM) has been commonly used in an integrative way for psoriasis patients for many years. Some CM therapies have shown therapeutic effects for psoriasis vulgaris (PV), including relieving symptoms and improving quality of life, and may reduce the relapse rate. However, explicit evidence has not yet been obtained. The purpose of the present trial is to examine the efficacy and safety of the YXBCM01 granule, a compound Chinese herbal medicine, with a combination of topical therapy for PV patients. METHODS/DESIGN: Using an add-on design, the trial is to evaluate whether the YXBCM01 granule combined topical therapy is more effective than topical therapy alone for the treatment of PV. The study design is a double-blind, parallel, randomized controlled trial comparing the YXBCM01 granule (5.5 g twice daily) to a placebo. The duration of treatment is 12 weeks. A total of 600 participants will be randomly allocated into two groups, YXBCM01 granule group and placebo group, from 11 general or dermatological hospitals in China. Topical use of calcipotriol betamethasone for the first 4 weeks and calcipotriol ointment for the remaining 8 weeks will be the same standard therapy for the two groups. Patients will be enrolled if they have a clinical diagnosis of PV, a psoriasis area severe index (PASI) of more than 10 or body surface area (BSA) of more than 10%, but PASI of less than 30 and BSA of less than 30%, are aged between 18 and 65-years-old, and provide signed informed consent. The primary outcome, relapse rate, is based on PASI assessed blindly during the treatment. Secondary outcomes include: (i) relapse time interval, (ii) time to onset, (iii) rebound rate, (iv) PASI score, (v) cumulative consumption of medicine, (vi) the dermatology quality life index (DLQI), and (vii) the medical outcomes study (MOS) item short form health survey (SF-36). Analysis will be on intention-to-treat and per-protocol subject analysis principles. DISCUSSION: To address the effectual remission of the YXBCM01 granule for PV, this trial may provide a novel regimen for PV patients if the granule can decrease relapse rate without more adverse effects.

[Exploration into rules of combined Chinese and Western medical treatment on immune infertility].

In order to explore the rules of combined Chinese and Western medical treatment on immune infertility, the study was carried out by searching relative primary documents from databases and 26 articles (dealing with 5865 cases) were screened out. Excel was used to perform the frequency analysis on the Western drugs and 27 Chinese recipes emerging in the documents separately. It was discovered that the combined use of Chinese and Western medicines has its superiority. Low dose glucocorticoids together with vitamine is the main Western treatment used, and dexamethasone is the most frequently used preparation of glucocorticoids. Among the 72 Chinese drugs presented in the 27 Chinese recipes, 13 appeared for more than 1800 times, they were Angelica sinensis, Salvia miltiorrhiza, Radix Paeoniae Rubra, Radix Astragali, Poria, Carthamus tinctorius, Phellodendron amurense, Scutellaria baicalensis, Anemarrhena asphodeloides, Rehmannia glutinosa, Cuscuta chinensis, Radix Paeoniae Alba and Radix Glycyrrhiza.
