OBJECTIVE: To explore the efficacy and safety of Zhuang medicine medicated thread moxibustion (ZMTM) on psoriasis vulgaris. METHODS: A multicenter, randomized, parallel controlled clinical trial was designed. A total of 241 outpatients with psoriasis vulgaris were randomly divided into a control group (120 cases) and a treatment group (121 cases) using a central block randomization from June 2015 to May 2018. The control group was treated with Western medicines alone including pidotimod dispersible tablets, vitamin B compound tablets, and compound cod liver oil-zinc oxide ointment. The treatment group was treated with ZMTM every 2 days combined with Western medicines. The two groups received continuous intervention for 30 days. The primary outcome was Psoriasis Area and Severity Index (PASI), and the secondary outcomes included Itch Rating Scale, Dermatology Quality of Life Index (DLQI), Hamilton Anxiety Rating Scale (HAMA), as well as PASI response rate. Meanwhile, adverse events were evaluated during the whole clinical trial. Follow-up was carried out 30 days after treatment. RESULTS: There were 5 cases of shedding in this trial. In intention-to-treat analysis, 236 cases were included and each group contained 118 cases. On the 30th and 60th days, PASI scores of patients in each group were significantly lower than that at baseline (P<0.01) and the PASI score reduction of the treatment group was greater than that of the control group (P<0.01). Itch Rating Scale, DLQI, and HAMA scale were decreased in both groups after treatment, and the treatment group showed a better therapeutic effect (P<0.01). The response rates of PASI 50 and 75 were significantly higher than those in the control group [81.4% (96/118), 43.2% (51/118) vs. 41.5% (49/118), 11.0% (13/118), respectively, P<0.05]. During follow-up, the improvements in scores of PASI, Itch Rating Scale, DLQI, and HAMA of the treatment group were significantly greater than those of the control group (P<0.01). The response rates of PASI 50 and 75 in the treatment group were significantly higher than those in the control group, respectively (both P<0.05). No obvious adverse reaction was found in either group. CONCLUSION ZMTM combined with Western medicines showed a better therapeutic effect in the treatment of psoriasis vulgaris without obvious adverse reaction.

Objective: To investigate the safety, feasibility and short-term efficacy of total laparoscopic loop ileostomy reversal in patients after resection of rectal cancer. Methods: The clinical data of 20 patients who underwent total laparoscopic loop ileoscopic loop ileostomy after radical resection of rectal cancer at Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, or Beijing Chaoyang District Sanhuan Cancer Hospital from October 2019 to June 2020 were collected and retrospectively analyzed. Results: All patients had successfully underwent total laparoscopic ileostomy reversal without conversion to open surgery or discontinued operation. No perioperative related death cases were found. In the whole group, the median operation time was 97 (60-145) minutes and the median intraoperative blood loss was 20 (10-100) milliliters. The median Visual Analogue Scale (VAS) score was 1.9 (1-5) one day after the operation. Nobody needed to use additional analgesic drugs. The median time to grand activities was 25 (16-42) hours, the median time to flatus was 44 (19-51) hours, and the median hospitalization after operation was 6.9 (5-9) days. No patients underwent operation related complications such as operative incision infection, abdominal and pelvic infection, intestinal obstruction, anastomotic leakage, bleeding and so on. Conclusions: Total laparoscopic loop ileostomy reversal appears to be safe, feasible and with promising efficacy for selected patients.

Background:The Food and Drug Administration recently announced that the use of morcellation may cause fibroids or pelvic dissemination and metastasis of uterine sarcoma;therefore,the use of morcellation is limited in the USA.A large sample study is necessary to assess the proportion of uterine malignant tumors found in patients with laparoscopic myomectomy.Methods:A national multicenter study was performed in China.From 2002 to 2014,33,723 cases were retrospectively selected.We calculated the prevalence and recorded the clinical characteristics of the patients with malignancy after morcellation application.A total of 62 cases were finally pathologically confirmed as malignant postoperatively.Additionally,the medical records of the 62 patients were analyzed in details.Results:The proportion of postoperative malignancy after morcellation application was 0.18％ (62/33,723) for patients who underwent laparoscopic myomectomy.Nearly 62.9％ (39/62) of patients had demonstrated blood flow signals in the uterine fibroids before surgery.And,23 (37.1％) patients showed rapid growth at the final preoperative ultrasound.With respect to the pathological types,38 (61.3％) patients had detectable endometrial stromal sarcoma,13 (21.0％) had detectable uterine leiomyosarcoma,only 3 (3.2％) had detectable carcinosarcoma,and 5 (8.1％) patients with leiomyoma had an undetermined malignant potential.Conclusions:The proportion of malignancy is low after using morcellation in patients who undergo laparoscopic myomectomy.Patients with fast-growing uterine fibroids and abnormal ultrasonic tumor blood flow should be considered for malignant potential,and morcellation should be avoided.

OBJECTIVETo study the changes in the intensity and temporal pattern of target gene expression in the tumor tissue of nude mice bearing human nasopharyngeal carcinoma (NPC) following injection of recombinant adeno-associated virus (rAAV) and recombinant adenovirus (AdV) in vivo.

METHODSEBV-positive human NPC cell line C666-1 was inoculated subcutaneouly in nude mice. After the tumor mass reached 3 mm in diameter, 1.5 × 10(11) v.g (virus genome) rAAV-EGFP, 2.5 × 10(8) pfu rAdV-EGFP or their balanced mixture was injected intratumorally. At 5 and 10 days after the injection, the tumor tissues were harvested for immunohistochemical staining of GFP, and the ratio of the GFP-positive cells and the intensity of GFP expression was determined.

RESULTSImmunohistochemistry for GFP showed that 5 days after the injection, GFP expression was detected (1.70 ∓ 0.48) in the tumor tissue in rAAV group, and the peak expression levels was seen in rAdV group (6.00∓1.94); the expression level was comparable between the combination group (6.90 ∓ 1.92) and rAdV group. At 10 days, GFP expression was considerably lowered to 2.00 ∓ 0.67 in rAdV group but increased to 8.00∓1.15 in rAAV group. The expression in the combination group maintained a high level at 10 days (10.10∓1.63), which was significantly higher than that in rAAV group (P%0.001).

CONCLUSIONTransfection with rAAV combined with rAdV allows instant, sustained and significantly enhanced expression of the target gene in the tumor tissue. This approach takes advantages of the two viruses and can be ideal for exogenous gene delivery into the tumor tissues.

OBJECTIVE: To investigate the expression of 18S rRNA and beta-actin mRNA in bloodstain between 8 and 15 days after death and extrapolate the time of bloodstain formation. METHODS: RNA in dried bloodstain at different times was extracted, then quantified for 18S rRNA and beta-actin mRNA by real-time RT-PCR. The bloodstain formation time was deduced based on the changes of the ratio of 18S rRNA to beta-actin mRNA at different time points. RESULTS The ratio of 18S rRNA to beta-actin mRNA increased gradually with time, indicating that rRNA and mRNA degraded in different rate with time. CONCLUSION; The ratio of 18S rRNA to beta-actin mRNA could be used for estimating the time of bloodstain formation in some period.

OBJECTIVETo in vitro study the inhibition effect and possible mechanism of As2S3 nanoparticles (As2S3 nano) on human MDS cell line MUTZ-1 and to compare with that of traditional As2S3.

METHODMUTZ-1 cells were treated with As2S3 nano and traditional regular-sized particles (TRSP) at different concentrations. The cell growth inhibition rate was determined by MTT assay, cell apoptosis by morphology and flow cytometry (FCM), cell cycle by FCM and the activity of caspase-3 by chemiluminescence assay.

RESULTSTreatment of As2S3 nano and TRSP at concentrations of 2, 4, 8 and 16 micromol/L for 48 h could lead to a significant dose-dependent decrease of MUTZ-1 cells and induce apoptosis. The percentages of inhibition were 48.9%, 75.9%, 89.4% and 96.5% in As2S3 nano vs 14.5%, 25.4%, 34.7% and 51.5% in TRSP and apoptosis rates were (12.9 +/- 1.9)%, (19.2 +/- 2.2)%, (30.1 +/- 2.5)% and (45.9 +/- 2.3)% in As2S3 nano vs (5.3 +/- 1.8%)%, (11.1 +/- 2.6)%, (19.3 +/- 2.3)% and (25.5 +/- 2.5)% in TRSP respectively. There was statistically significant difference in these two groups (P < 0.01). The proportion of cell in G2/M phase and the activity of caspase-3 of MUTZ-1 cells treated with A2S32 nano were significantly higher than those treated with control group and As2S3 TRSP groups (P < 0.01).

CONCLUSIONSAs2S3 nanoparticles and TRSP can inhibit the proliferation of MUTZ-1 cells and induce apoptosis, which maybe through activating caspase-3 pathways and increasing the proportion of G2/M phase. As2S3 nanoparticles can produce a much better antitumor effect than As2S3 TRSP do.

OBJECTIVETo assess the feasibility of the 10 microg recombination yeast hepatitis B vaccine in the expanded applicable population group aged 5 - 18.

METHODSPeople with both HBsAg and anti-HBs negative were selected to take two-stage clinical experiment and the safety and immunogenicity were observed. Safety observation was conducted in 925 subjects, while 568 for immunogenicity. The observation group (aged 5 - 18) included 493 subjects, and (age > 18) 75 enrolled in control group. For the observation group, there were three sub-groups including a child group (141, aged 5 - 6), early youth group (177, aged 12 - 13), and youth group (175, aged 16 - 18). Both groups were administered with 10 microg recombination yeast hepatitis B vaccines with 3 doses at 0 month, 1st month, 6th month. To assess the immunogenicity, the vaccination reactions were observed during the following 4 weeks in order to assess the vaccine safety. The blood samples were taken during 4 - 6 weeks after fully vaccinated, and then anti-HBs were tested with RIA and analyzed by comparing the positive rate of anti-HBs, the geometric mean titer (GMT) and the protective rate between the two groups.

RESULTSBoth observation and control group didn't show any general reactions, adverse events following immunization (AEFI) or coincidental cases when observed at 0.5 h, 6 h, 24 h, 48 h, 72 h, 1 week, 2 weeks, 3 weeks, 4 weeks after being vaccinated. The result of serum test showed, the positive rates of child group, early youth group, youth group and control group were respectively 100.00% (141/141), 97.18% (172/177), 98.29% (172/175) and 89.33% (67/75); the GMTs of anti-HBs were respectively 440.28, 875.38, 467.80, 131.06 U/L; the protective rates were respectively 100.00% (141/141), 97.18% (172/177), 97.14% (170/175) and 86.67% (65/75). The positive rate, GMT and protective rate of the experimental group were all higher than that of control group (chi(2)(positive rate) = 12.77, 5.12, 7.99; t(GMT) = 3.89, 4.13, 5.91; chi(2)(protective rate) = 16.81, 8.60, 8.44; P < 0.05).

CONCLUSIONThis vaccine could be expanded to 5 - 18 year-old population with safety and effectiveness, the positive rate and protective rate of anti-HBs were both higher than that of control group.
