Effect of new Pulian Ointment () in treating psoriasis of blood-heat syndrome: A randomized controlled trial / 中国结合医学杂志

<p><b>OBJECTIVE</b>To objectively assess the clinical efficacy and safety of a new Pulian Ointment (, NPLO) in treating psoriasis of blood-heat syndrome of Chinese medicine.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSION</b>NPLO is a Chinese remedy for the external treatment of psoriasis of the blood-heat syndrome with a reliable therapeutic efficacy and good safety.</p>

Comparison between immunofluorescence and PCR in detecting human papilloma virus in condyloma acuminata / 中国医学科学杂志(英文版)

<p><b>OBJECTIVE</b>To compare the effectiveness of immunofluorescence and polymerase chain reaction (PCR) in detecting human papilloma virus (HPV) in condyloma acuminata (CA).</p><p><b>METHODS</b>HPVs in CA tissues from 60 patients were detected by immunofluorescence and PCR, respectively. Different subtypes of HPVs were also identified with restriction fragment length polymorphism (RFLP).</p><p><b>RESULTS</b>The positive detective rates of immunofluorescence and PCR were 56.67% (34/60) and 96.67% (58/ 60), respectively (P < 0.01). RFLP results showed HPV6 and HPV11 were the main subtypes in the detected virus, which accounted for 98.28%.</p><p><b>CONCLUSION</b>The sensibility of PCR is superior to that of immunofluorescence.</p>

Detecting HPV DNA in tissues of external genital squamous cell carcinoma in situ by PCR-RFLP technique / 中国医学科学院学报

<p><b>OBJECTIVE</b>To study the relationship between the infection of human papillomavirus (HPV) and external genital squamous cell carcinoma in situ.</p><p><b>METHODS</b>HPV DNA was detected with the consensus primer by polymerase chain reaction (PCR) and its type was determined by restriction fragment length polymorphism (RFLP).</p><p><b>RESULTS</b>HPV DNA was detected and HPV16 was the most frequently identified type in 29 (56.9%) of 51 cases of external genital squamous cell carcinoma in situ. HPV DNA was positive in 22 (55%) of 40 cases of bowenoid papulosis, among which 20 were of HPV16 type, one of HPV31 type, and one of HPV6 + 16 type. HPV DNA was positive in all 5 cases (100%) of Bowen's disease, among which 4 were HPV16 type and one of HPV6 + 16 type. HPV DNA was positive in 2 (33.3%) of 6 Queyrat erythroplasia cases and all were of HPV16 type.</p><p><b>CONCLUSION</b>HPV16 infection is strongly associated with the external genital squamous cell carcinoma in situ including bowenoid papulosis, Bowen's disease, and Queyrat erythroplasia.</p>
