Adjunctive Chinese medicine therapy reduces relapse of psoriasis vulgaris after discontinuation of biologics: a prospective registry-based cohort study.

BACKGROUND: Biologics have revolutionized psoriasis treatment; however, relapse of psoriasis after discontinuation of biologics remains unresolved. OBJECTIVE: To assess the impact of adjunctive Chinese medicine (CM) therapy on relapse of psoriasis vulgaris (PV) after discontinuation of biologics. METHODS: We constructed a prospective cohort study through a psoriasis case registry platform that enrolled patients treated with biologics (in combination with or without CM). The endpoint event was relapse, defined as loss of psoriasis area and severity index (PASI) 75. RESULTS: A total of 391 patients completed the study and were included in the analysis, of whom 169 (43.2%) experienced relapse during follow-up. To minimize the bias, a 1:1 propensity score matching (PSM) was performed, generating matched cohorts of 156 individuals per group. Adjuvant CM therapy significantly associated with reduced incidence of relapse (HR =0.418, 95% CI = 0.289 ∼ 0.604, p < 0.001), and the protective effect of CM in the subgroup analysis was significant. In addition, PASI 90 response and disease duration were associated with relapse (p < 0.05). CONCLUSION: Adjunctive CM therapy is associated with reduced relapse incidence in PV after discontinuation of biologics.

Association of Complete Blood Cell Count-Derived Inflammatory Biomarkers with Psoriasis and Mortality.

Background and Aim: Psoriasis is a persistent inflammatory disorder that affects 3% of the population and is associated with cardiovascular diseases. Therefore, this study aimed to investigate the correlations between complete blood cell count (CBC)-derived inflammatory biomarkers, psoriasis prevalence, and all-cause mortality. Methods: Data were obtained from the National Health and Nutrition Examination Survey (NHANES) spanning 2003-2006 and 2009-2014. Mortality data up to December 31, 2019 were obtained using the National Death Index. The following CBC-derived inflammatory biomarkers were examined: neutrophil/lymphocyte ratio (NLR), neutrophil/(white blood cells - neutrophils) ratio (dNLR), monocyte count/lymphocyte ratio (MLR), (neutrophil + monocyte)/lymphocyte ratio (NMLR), platelet/lymphocyte ratio (PLR), and systemic inflammatory response index (SIRI). Weighted logistic and Cox regression analyses were used to calculate odds ratios, hazard ratios, and the corresponding 95% confidence intervals. Additionally, the prognostic value of the inflammatory indicators was assessed and ranked using the random survival forest approach. Results: In total, data from 21,431 participants with average age of 45.02 ± 0.27 years (49.51% male) were included in the study, among which 600 participants were positive for psoriasis (prevalence rate, 2.80%). Additionally, 79 all-cause deaths were recorded during a median follow-up period of 8.83 (6.67-11.00) years. Moreover, NLR, dNLR, NMLR, PLR, and SIRI were positively associated with the prevalence of psoriasis. Furthermore, MLR, NMLR, and SIRI were positively correlated with all-cause mortality in patients with psoriasis, with NMLR being the most valuable predictor of all-cause mortality. Conclusion: CBC-derived inflammatory biomarkers were associated with psoriasis prevalence, NMLR, SIRI, and MLR values were associated with all-cause mortality in patients with psoriasis. Overall, assessment of these CBC-derived indicators may serve as a simple method for screening high-risk individuals among patients with psoriasis.

Effect and safety of probiotics for treating urticaria: A systematic review and meta-analysis.

BACKGROUND: To assess the effect and safety of probiotics for treating urticaria. METHODS: Randomized controlled trial (RCT) papers on the probiotics treatment published before May 2019 were retrieved from various databases like PubMed, EMbase, MEDLINE (Ovid), SCI-Hub, Springer, ClinicalKey, VIP, and CNKI. The treatment plan that we include are oral administration of single probiotic, multiple probiotics, and the combination of probiotics and antihistamines. Meta-analysis of the data was performed by RevMan 5.3 software. RESULTS: A total of nine RCT papers were included: four papers for oral administration of single probiotic, three papers for oral administration of multiple probiotics, and two papers for oral administration of a probiotic combined with antihistamines. The results of meta-analysis showed that the therapeutic effect of the probiotic group was significantly higher than the control group (placebo or antihistamines) (RR = 1.09, 95% CI: 1.03-1.16, p = 0.006). And compared with the placebo group, the therapeutic effect of single probiotic group was significantly improved (RR = 1.11, 95% CI: 1.01-1.21, p = 0.03). Regarding therapeutic effect, there was no statistically significant difference between the multiple probiotics group and placebo group (RR = 1.00, 95% CI: 0.94 ~ 1.07, p = 0.91); the therapeutic effect of single probiotic combined antihistamine group was significantly higher than the antihistamine group (RR = 1.13, 95% CI: 1.07-1.19, p < 0.0001). Regarding the incidence of adverse reactions, there was no significant difference between the probiotic group and the control group (p = 0.46). CONCLUSION: The treatment plan of oral administration of probiotics has significant therapeutic effects on urticaria, but the therapeutic effects of the administration of multiple probiotics and the safety of probiotic therapy are still not yet obvious. Some large-scale, multi-centered RCT studies are needed in the future for clarification.

Efficacy of Modified Qufeng Runmian Powder () on Acne Vulgaris with Syndromes of Dampness and Blood Stasis: A Multicenter, Randomized, Double-Blind, Placebo-Controlled Clinical Trial.

OBJECTIVE: To evaluate the efficacy and safety of a Chinese medicine (CM) Modified Qufeng Runmian Powder (, MQFRMP) for the treatment of acne vulgaris with CM syndromes of dampness and blood stasis. METHODS: In this multicenter, randomized, double-blind, placebo-controlled clinical trial, 220 acne vulgaris patients with CM syndrome of dampness and blood stasis were included and randomly assigned using a central area group random design to receive either MQFRMP or the placebo, with 110 cases in each group. MQFRMP or a placebo at 145 g/bag were administered once daily for 4 weeks, respectively. The primary index of efficacy was the effective rate according to the acne severity score (ASS). The secondary indices of efficacy included the changes in the dermatology life quality index (DLQI) score, VISIA scores (spots, pores, brown spots, porphyrins and red areas) and skin assessment (skin pH, sebum amount and hydration) according to a SOFT skin multianalyzer. RESULTS: (1) Follow-up: a total of 204 patients completed the follow-up, with 103 in the treatment group and 101 in the control group. (2) Effective rate: the total effective rate of the treatment group was significantly higher than the control group [83.5% (86/103) vs. 31.7% (32/101), P<0.01)] with 95% confidence interval of 39.3%-66.4%. (3) DLQI: DLQI scores were significantly decreased the treatment and control groups (both P<0.01), but the treatment group was more obvious than the placebo group (P<0.01). (4) VISIA scores: the scores of spots, brown spots and red areas in the treatment group decreased compared with baseline (P<0.05). In the control group, the scores of brown spots and pores decreased compared with baseline (P<0.05). The improvement was more obvious in the treatment group than in the control group for all items (P<0.05). (5) Skin assessment: the pH and sebum score in the both groups decreased drastically compared with the baseline (all P<0.01), however, the improvement was more obvious in the treatment group than in the control group (P<0.01). The hydration amount in the two groups showed no statistically significant difference compared with the baseline (both P>0.05). (6) Safety: two cases of mild drug allergy were observed in the treatment group. CONCLUSION: MQFRMP was effective and safe for the treatment of acne vulgaris with syndromes of dampness and blood stasis. (No. ChiCTR1900020479).

Numerical evaluation of ablation zone under different tip temperatures during radiofrequency ablation.

The present study aimed at investigating the relationship between the shape and size of ablation zone and the ablation time during radiofrequency ablation (RFA) at different tip temperatures (80, 85, 90, and 95 °C). A two-dimensional simulation model of liver RFA using single-electrode was first built by finite element method (FEM). A closed-loop proportional-integral (PI) controller was employed in the FEM model. The heat transfer issues were solved based on Pennes biological equation. To improve simulation accuracy of the FEM models, temperature-dependent forms of the electrical conductivity and the thermal conductivity were adopted in the model. The ablation zone was assessed by 54 °C isothermal contour (IT54). The ablation zone sizes obtained from the numerical simulations and ex vivo experiments were compared to evaluate the validity of the numerical model. All the four tip temperatures (80, 85, 90, and 95 °C) were tested using 3 ex vivo porcine livers respectively. According to numerical simulation results, the characterization functions of the ablation volume and the ablative margin (AM) were derived. The proposed curve functions could precisely characterize the shape and size of ablation zone at different preset tip values, and the statistical results showed that the prediction curves had a good consistency with simulation curves. This paper proposed the prediction models of the ablation zone in the RFA process, which could be used to achieve accurate planning of RFA needle placements and optimize patient care during temperature-controlled RFA therapy.

Whether Fire-needle Therapy Benefits Plaque Psoriasis: A Multicenter, Randomized, and Controlled Trial.

OBJECTIVE: To observe the clinical effectiveness and safety of fire-needle therapy, an external approach of Chinese medicine in treating plaque psoriasis. METHODS: This study was a two-parallel-arm randomized controlled trial. A total of 151 participants with plaque psoriasis were randomly assigned to the fire-needle therapy group (treatment group, 76 cases) or the control group (75 cases) at a 1:1 allocation ratio using SAS software. All participants received Oral Huoxue Jiedu Decoction (, HXJDD) and applied externally vaseline cream twice a day. Participants in the treatment group received fire-needle therapy once weekly for 4 weeks plus HXJDD and vaseline cream applied the same as the control group. The primary outcome measure was Psoriasis Area and Severity Index (PASI) score, and the secondary outcomes were Dermatology Life Quality Index (DLQL), and Hamilton Anxiety Rating Scale (HAMA), as well as Chinese medicine (CM) syndrome score and photos of target lesions. The indices were evaluated before and after treatment. RESULTS: Sixty-eight patients in each group completed the study. The treatment group has not yet achieved significant improvement in PASI score (P>0.05) compared to the control group. However, significant differences were found between the two groups in relieving CM syndrome (P<0.05) and improving quality of life (P<0.05). CONCLUSION: Fire-needle appears to be safe and may have benefit for psoriasis, the short-term treatment and small sample size limit the conclusions of this study. Further rigorous randomized controlled trials with longer treatment are recommended.

Nicorandil alleviated cardiac hypoxia/reoxygenation-induced cytotoxicity via upregulating ketone body metabolism and ACAT1 activity.

To study the effect of nicorandil pretreatment on ketone body metabolism and Acetyl-CoA acetyltransferase (ACAT1) activity in hypoxia/reoxygenation (H/R)-induced cardiomyocytes. In our study, we applied H9c2 cardiomyocytes cell line to evaluate the cardioprotective effects of nicorandil. We detected mitochondrial viability, cellular apoptosis, reactive oxygen species (ROS) production and calcium overloading in H9c2 cells that exposed to H/R-induced cytotoxicity. Then we evaluated whether nicorandil possibly regulated ketone body, mainly ß-hydroxybutyrate (BHB) and acetoacetate (ACAC), metabolism by regulating ACAT1 and Succinyl-CoA:3-keto-acid coenzyme A transferase 1 (OXCT1) protein and gene expressions. Nicorandil protected H9c2 cardiomyocytes against H/R-induced cytotoxicity dose-dependently by mitochondria-mediated anti-apoptosis pathway. Nicorandil significantly decreased cellular apoptotic rate and enhanced the ratio of Bcl-2/Bax expressions. Further, nicorandil decreased the production of ROS and alleviated calcium overloading in H/R-induced H9c2 cells. In crucial, nicorandil upregulated ACAT1 and OXCT1 protein expressions and either of their gene expressions, contributing to increased production of cellular BHB and ACAC. Nicorandil alleviated cardiomyocytes H/R-induced cytotoxicity through upregulating ACAT1/OXCT1 activity and ketone body metabolism, which might be a potential mechanism for emerging study of nicorandil and other KATP channel openers.

[Treatment of EGFRIs-related Skin Adverse Reactions by Zhiyang Pingfu Lotion].

Objective To observe the curative effect of Zhiyang Pingfu Lotion (ZPL) for its ex- ternal application in treatment of epidermal growth factor receptor inhibitors (EGFRIs)-related acneiform rash, cutaneous pruritus , xerosis cutis , and nail changes , as well as to evaluate its safety and patients' satisfaction. Methods Recruited were 201 patients with confirmed pathological diagnosis, who had acne- iform rash after using EGFRIs. They were assigned to the treatment group (131 cases) and the control group (70 cases) by random digit table. Patients in the treatment group were externally applied with self- formulated ZPL based on principles of Western medical standards, while those in the control group were externally applied with blank drugs plus conventional Western medicine standard. The therapeutic course for all was 14 days. Changes in rash degree, cutaneous pruritus, xerosis cutis, and nails were observed in both groups before and after treatment. Blood routines as well as liver and kidney function tests were performed in both groups before and after treatment. Follow-up visit was also conducted during progression-free survival (PFS). Results A total of 185 patients finished this clinical trial. Ten dropped out in the treatment group and 6 in the control group. The effective rates of rash degree, cutaneous pruritus, xerosis cutis, and nail changes were 90.1 % (109/121 ), 57.9% (70/121 ), 57. 9% (70/121 ), and 16. 5% (20/121) in the treatment group, respectively. They were 14. 1% (9/64), 6. 3% (4/64), 1. 6% (1164), and 0 (0/64) in the control group, respectively. Significant difference existed in all these indices between the two groups (X² = 105. 1022, 51. 3312, 59. 1777; P <0. 05). No serious drug-related adverse events occurred during clinical observation, with relatively better safety. The satisfaction was 95. 40% (125/131) in the treatment group and 57. 1 % (40/70) in the control group. No statistical difference in PFS was observed between the two groups (X² = 2. 006, P > 0. 05). Conclusions ZPL had significantly curative effect in treatment of EGFRIs-related skin adverse reactions, with no obvious adverse reactions. Howev- er, more randomized control trials are needed to verify these findings.

Interleukin-21 is associated with the severity of psoriasis vulgaris through promoting CD4+ T cells to differentiate into Th17 cells.

Interleukin-21 (IL-21) and T helper 17 (Th17) cells are known to be involved in the pathogenesis of psoriasis, but little is known about their relationship in psoriasis. Herein, we investigated whether IL-21 could regulate Th17 cell induction in patients with psoriasis vulgaris. 32 patients with psoriasis vulgaris and 13 healthy controls were recruited. Flow cytometry was used to detect the frequencies of cells mainly secreting IL-21 (including IL-21+CD4+ T and IL-21+ Th17 cells) and Th17 cells. An enzyme-linked immunosorbent assay (ELISA) was used to determine the serum content of IL-21. Severity of the psoriasis was evaluated by a Psoriasis Area and Severity Index (PASI) score. In addition, the differentiation of CD4+ T cells with IL-21 and the different frequencies of IL-21+CD4+ T cells, IL-21+ Th17 cells and Th17 cells were assessed, as were serum levels of IL-21 in patients with moderate to severe psoriasis before and after treatment. Our results showed that the levels of IL-21, IL-21+CD4+ T cells, IL-21+ Th17 cells and Th17 cells were significantly increased in patients and positively associated with PASI score (P < 0.01). Moreover, the levels of IL-21, IL-21+CD4+ T cells and IL-21+ Th17 cells were positively correlated with the frequency of Th17 cells (P < 0.01). In vitro experiments demonstrated that IL-21 could promote CD4+ T cells to differentiate into Th17 cells. After a 4-week treatment of acitretin and a topical therapy, all the immune markers observed in patients decreased significantly (P < 0.01), but the levels remained higher than those in healthy controls (P < 0.01). These findings indicate that IL-21 might promote Th17 cell induction in psoriasis and might be a potential immune marker for targeting this disease.

[Treatment of Epidermal Growth Factor Receptor Inhibitors Associated Adverse Skin Reactions by Zhiyang Pingfu Liquid: a Clinical Study].

OBJECTIVE: To study the curative effect of Zhiyang Pingfu Liquid (ZPL) in treating epidermal growth factor receptor inhibitors (EGFRIs) associated adverse reactions of the skin. METHODS: All 54 patients with pathologically confirmed malignant tumor had EGFRIs induced adverse reactions of the skin to various degrees. ZPL was externally applied for them all, once or twice per day, 14 days consisting of one therapeutic course. Changes of adverse skin reactions, time for symptoms relief, adverse skin reaction types suitable for ZPL were observed before and after treatment. RESULTS: EGFRIs associated skin adverse reactions were improved to various degrees after they used ZPL. The shortest symptoms relief time was 1 day while the longest was 12 days, with an average of 6.93 days and the median time 7 days. Compared with before treatment, itching, rash/scaling, acne/acneform eruptions were obviously improved (P < 0.05). CONCLUSION: ZPL could alleviate EGFRls associated adverse skin reactions, especially showed better effect on itching, rash/scaling, acne/acneform eruptions.

Two new susceptibility loci 1q24.2 and 11p11.2 confer risk to severe acne.

Severe acne is a chronic inflammatory skin disorder characterized by widespread inflammatory lesions including nodules, cysts and potential scarring. Here we perform the first genome-wide association study of severe acne in a Chinese Han population comprising 1,056 cases and 1,056 controls using the Illumina HumanOmniZhongHua-8 BeadChip. In an independent cohort of 1,860 cases and 3,660 controls of Chinese Han, we replicate 101 SNPs of which 3 showed consistent association. We identify two new susceptibility loci at 11p11.2 (DDB2, rs747650, P(combined)=4.41 × 10⁻9 and rs1060573, P(combined)=1.28 × 10⁻8) and 1q24.2 (SELL, rs7531806, P(combined)=1.20 × 10⁻8) that are involved in androgen metabolism, inflammation processes and scar formation in severe acne. These results point to new genetic susceptibility factors and suggest several new biological pathways related to severe acne.

A randomized controlled trial comparing total glucosides of paeony capsule and compound glycyrrhizin tablet for alopecia areata.

OBJECTIVE: To observe the efficacy and safety of total glucosides of paeony capsule (TGPC) in patients with mild and moderate alopecia areata. METHODS: A total of 86 outpatients were randomly allocated into two groups of TGPC (treatment, 44 cases) and compound glycyrrhizin tablet (control, 42 cases). The treatment group was given oral TGPC, three times daily and 600 mg per time; the control group was given oral compound glycyrrhizin tablets, three times daily and 50 mg per time. In addition, both groups were given 10 mg of vitamin B(2) and tapped the bold patches with massage. The treatment course was three months for both groups. Peripheral blood T-cell subsets (CD3(+)CD4(+), CD3(+)CD8(+), Th, Ts, Th/Ts) of 10 patients randomly selected from each group respectively were tested before and after three months of treatment. The effectiveness and adverse reaction of all cases were observed each month. The safety was evaluated according to the incidence rate of adverse reaction. RESULTS: In the treatment group, the cured and markedly effective rate was 36.36% (16/44), 50.00% (22/44) and 68.18% (30/44) at the end of first, second and third month of treatment, respectively, and the incidence rate of adverse reaction was 13.64% (6/44). In the control group, the cured and markedly effective rate was 38.10% (16/42), 57.14% (24/42) and 71.43% (30/42), respectively, and the incidence rate of adverse reaction was 16.67% (7/42). The cured and markedly effective rate and the incidence rate of adverse reaction were similar in both groups (P>0.05). TGPC and compound glycyrrhizin tablet can inhibit CD3(+)CD4(+) and CD3(+)CD8(+), and decrease the ratio of Th/Ts (P<0.05). CONCLUSION: TGPC is effective and safe in the treatment of alopecia areata.

Efficacy of externally applied Chinese herbal drugs in treating psoriasis: a systematic review.

OBJECTIVE: To assess the efficacy and safety of external application of Chinese herbal drugs (ex-CHD) in the treatment of psoriasis. METHODS: Literature regarding randomized clinical trials (RCTs) of psoriasis treatments with ex-CHD, either alone or combined with Western medicine (WM) or physiotherapy, controlled by untreated, placebo or WM treatment were found in electronic databases, including PubMed/MEDLINE, EMBASE, Cochrane Library, Cochrane Central Register of Controlled Trials, China Biology Medicine Disc (CBM), Chinese National Knowledge Infrastructure (CNKI), Wanfang database and VIP database from their inception through July 2011. Study selection, data extraction, quality assessment, and data analyses were conducted according to the Cochrane standards. RESULTS: A total of 10 randomized trials (involving 1,435 patients) were included. Because both test and control drugs used in the RCTs were different from each other, the effects can only be described singly and calculated. Regarding the total effective rate for the treatment of psoriasis, ex-CHD in combination with ultraviolet radiation b (UVB) or narrow band ultraviolet radiation b (NB-UVB), which was reported in 6 trials, was superior to UVB alone. One study reported that ex-CHD and externally applied WM had equivalent effects. In another study, ex-CHD showed better results than placebo. However, another two comparisons of ex-CHD and WM (all in combining with oral WM) showed uncertain outcomes. Nine trials reported adverse reactions. Of these, 7 RCTs included statistical analysis. The results showed that the side-effects that occurred in ex-CHD combined with UVB were less severe than those caused by UVB alone, but the incidence was roughly the same as WM. CONCLUSION: The evidence supporting the efficacy of ex-CHD with respect to treating psoriasis is quite limited and must be strengthened by high-quality studies.

Literature research of Chinese medicine recipes for the treatment of psoriasis vulgaris with blood-heat syndrome type.

OBJECTIVE: To analyze and investigate the rules for drug utilization of Chinese medicine for the treatment of psoriasis vulgaris with blood-heat syndrome. METHODS: The literatures that met the following inclusion criteria were screened out from China National Knowledge Infrastructure (CNKI) from January 1998 to December 2008, including the compositions and dosages of the recipes reported completely and accurately, the sample size being [Symbol: see text] 30 cases and the total effective rate being [Symbol: see text] 70%. RESULTS: In total, 289 papers meeting the inclusion criteria were retrieved, involving 301 recipes; in which 111 recipes consisting of 145 individual drugs were the function for clearing the heat, accounting for 52.84%. The three drugs with the highest utilized frequency were Radix Rehmanniae, Radix Arnebiae seu Lithospermi and Cortex Moutan. Meridian adscription of the drugs was mainly the Gan-meridian. CONCLUSION: There were rules for the treatment of psoriasis vulgaris of blood-heat syndrome with Chinese medicine prescriptions.

Effect of Chinese herbal medicine combined with acitretin capsule in treating psoriasis of blood-heat syndrome type.

OBJECTIVE: To observe the clinical curative effect of Chinese herbal medicine combined with acitretin capsule in treating psoriasis of blood-heat syndrome (P-BH). METHODS: Eighty patients of P-BH were randomly assigned to two groups, 39 in Group A and 41 in Group B. Both was treated with Chinese herbal medicines for clearing heat, cooling blood and removing toxic substance, and acitretin capsule was given to Group A additionally, with 8 weeks as one therapeutic course. The clinical curative effect was compared between groups, and the change of psoriasis activity severe index (PASI) scores before and after treatment was observed. RESULTS: The total effective rate in Group A was 84.2% and that in Group B 68.2%, also showing significance between groups (P<0.01). PASI score lowered significantly after treatment in both groups, showing statistical significance (P<0.01), but no significant difference between groups. Little adverse reaction was found in Group B, while in Group A, the adverse reaction was of even milder degree, which could be alleviated by adjusting the herbal medicine and symptomatic treatment administration. CONCLUSIONS: The effect of Chinese herbal medicine combined with acitretin capsule was superior to Chinese herbal medicine alone in treating P-BH, but the adverse reaction of acitretin capsule could be alleviated by adjusting the herbs used. However, the result is waiting to be verified further by larger samples.

METHODS: A total of 108 patients with psoriasis of blood-heat syndrome were equally assigned, using a randomizing digital table, to the test group treated externally with NPLO and the control group treated with placebo; the medication was done using a singleblinded method twice a day. Meanwhile, all patients received by oral intake a conventional Chinese decoction for clearing heat and cooling blood; the therapeutic course was 4 weeks for both groups. The therapeutic efficacy, changes in the Psoriasis Area and Severity Index (PASI) score and various aspects of the lesion, including scaly eruption, erythema, infiltration, size, score of itching as well as adverse reactions were observed. RESULTS: The trial was completed in 100 patients, 51 in the test group and 49 in the control group. The remarkably effective rate was 45.10% and the total effective rate was 84.31% in the test group, which were significantly higher than those in the control group, 12.24% and 51.02%, respectively, showing a significant difference between groups (P<0.01). The test group also showed better effects in the improvement of the PASI score of the lesions and scores on erythema, infiltration, size of lesion as well as itching. No adverse event was found in either group. CONCLUSION: NPLO is a Chinese remedy for the external treatment of psoriasis of the blood-heat syndrome with a reliable therapeutic efficacy and good safety.

[Clinical study on treatment of acute eczema by Shuangfujin].

OBJECTIVE: To evaluate the effects and safety of Shuangfujin (SFJ) on acute eczema. METHODS: One hundred and twenty patients with acute eczema were randomly assigned to 4 groups equally, the saline group, the boric acid group, the Pifukang lotion group and the SFJ group, treated with respective medicine. RESULTS: After 4 days of treatment, the symptom score was remarkably lower in the SFJ group than in the other three groups (P<0.01), score in the saline group was higher than that in the boric acid group and the Pifukang lotion group, and insignificant difference was shown between the latter two groups. The total effective rate and cured rate were 46.4% and 14.3% in the SFJ group, which were matched to those in the Pifukang lotion group and significantly higher than those in the other two groups (P <0.01), and the saline group showed the lowest efficacy. The effect of stopping itch in the SFJ and the boric acid group were matched, which was higher than that in the Pifukang lotion group, and the lowest was in the saline group. No skin irritant reaction and other adverse reactions were found. CONCLUSION: SFJ is effective, safe and convenient in treating acute eczema.
