OBJECTIVETo explore efficacy enhancing and detoxification roles of Jiedu Quyu Zishen Recipe (JQZR) in treating systemic lupus erythematosus (SLE) by studying its effect on Toll like receptor 9 (TLR9) signal pathway of murine macrophage cells after JQZR stimulated CpG oligodeoxynucletide (CpG ODN).

METHODSMurine macrophage cells in vitro cultured were randomly divided into 4 groups, i.e., the blank serum group, the CpG ODN stimulus group, the CpG ODN + dexamethasone group, the CpG ODN + medicated serum group. Murine macrophage cells were collected after 24-h intervention. The expression of TLR9, myeloid differentiation factor 88 (MyD88), NF-KB, IFN-α mRNA were analyzed by RT-PCR. The expression of TLR9 and NF-κB protein were analyzed by Western blot. Changes of the NF-KB transcriptional activity were assayed by Dual-Luciferase reporter assay system.

RESULTSmRNA expressions of TLR9, MyD88, NF-κB, and IFN-α, protein expressions of TLR9 and NF-κB, and NF-κB transcriptional activities were enhanced, showing statistical difference when compared with those of the blank serum group (P <0. 05, P <0. 01). Compared with the CpG ODN stimulus group, mRNA expressions of MyD88, NF-κB, and IFN-α, the protein expression of NF-κB and the NF-κB transcriptional activities decreased in the CpG ODN + dexamethasone group with statistical difference (P <0. 01). Compared with the CpG ODN stimulus group, mRNA expressions of TLR9, MyD88, NF-κB, and IFN-α, protein expressions of TLR9 and NF-κB, and NF-κB transcriptional activities were decreased in CpG ODN+ medicated serum group with statistical difference (P <0. 01).

CONCLUSIONEfficacy enhancing and detoxification roles of JQZR in treatment of SLE might be realized through regulating TLR9 signal pathways.

Objective To report a case of the implantation of thyroid hyperplastic or neoplastic tissue after endoscopic thyroidectomy and discuss this complication in aspects of prevalence, pathogenesis, protection, and therapies.
Methods A systematic search of literature from the PubMed database was conducted for identifying eligible studies on implantation of thyroid hyperplastic or neoplastic cells after endoscopic thyroid surgery.
Results Overall, 5 reported cases on patients suffering from endoscopic thyroid surgery with implantation of thyroid hyperplastic or neoplastic cells were included in the systematic review.
Conclusions Unskilled surgeons, rough intraoperative surgical treatment, scarification or rupture of tumor, contamination of instruments, chimney effect, aerosolization of tumor cells may be associated with the implantation after endoscopic thyroidectomy. To minimize the risk of such complication, we should be more meticulous and strict the endoscopic surgery indications.

Objective To retrospectively evaluate the diagnosis and treatment of Mirizzi syndrome (MS).
Methods Patients who received elective or emergency cholecystectomies in our center during 23 years were retrospectively evaluated. The data reviewed included demography, clinical presentations, diagnostic methods, surgical procedures, postoperative complications, and follow-up.
Results There were 27 patients diagnosed with MS among 8697 cholecystectomies performed during that period. The preoperative diagnostic modalities included ultrasonography, computed tomography, magnetic resonance cholangiopancreatography, and endoscopic retrograde cholangiopancreatography. The incidence of MS Type I (12/27, 44.4%) had the dominance in the four types, the incidence of MS Type II and III were 33.3% (9/27) and 22.2% (6/27), and there were no MS Type IV patients. Laparoscopic cholecystectomy was performed in 15 (55.6%) patients, but only 3 (11.1%) patients with MS Type I had a successful surgery, and the other 12 were converted to open cholecystectomy. The remaining 12 patients directly underwent open cholecystectomy. The surgical procedures except laparoscopic cholecystectomy included simply open cholecystectomy (including laparoscopic cholecystectomy converted to open cholecystectomy) (6/27, 22.2%), open cholecystectomy, T-tube placement with choledochotomy (9/27, 33.3%), open cholecystectomy, closure of the fistula with gallbladder cuff, T-tube placement (3/27, 11.1%), and open cholecystectomy with excision of the external bile ducts, and Roux-en-Y hepatico-jejunostomy (6/27, 22.2%). Of them, 88.9% (24/27) patients recovered uneventfully and were discharged in good condition without any operation related mortality.
Conclusions Endoscopic retrograde cholangiopancreatography is a good method with diagnostic and therapeutic purposes. Total or partial cholecystectomy is generally adequate for MS Type I. For MS Type II-IV, paritial cholecystectomy, choledochoplasty, or if impossible, Roux-en-Y hepatico-jejunostomy may be performed. Laparoscopic cholecystectomy may be successful in selected preoperatively diagnosed MS Type I patients, and open cholecystectomy is the standard therapeutic method.

Objective To clone and sequence the cysteine protease inhibitor gene of periodic Brugia malayi(BmCPI) and predict B-cell epitopes in amino acide sequence of BmCPI in order to provide basis for further study the expression of BmCPI and its function. Methods Total RNA was extracted from periodic Brugia malayi.A couple of specific primers were designed on the basis of known sequences of cysteine protease inhibitor gene from BmCPI. The desired gene was amplified by PCR technique from cDNA. The PCR products were purified and cloned into plasmid pGEM-T by T-A cloning method, transformed into Escherichia coli(E, coli) strain DH5α. The recombinant plasmids were screened and identified by digestion with restriction enzyme and PCR amplification. Five parameters and methods were used to predict B-cell epitopes in amino acide sequence of BmCPI. Results For RT-PCR, a specific band of around 621 bp was amplified. The same band was obtained by double restriction of recombinant plasmids or PCR using recombinant plasmid as template. The result of DNA sequencing showed that BmCPI shares 99% nucleotide sequence identity with that of published sequence. It showed that B-cell epitopes were probably at or adjacent to 23 - 32, 50 - 79 and 117 - 126 in its amino acide sequence. Conclusions pGEM-BmCPI is successfully constructed and sequenced, anticipated objective is reached and conditions is provided for further study of BmCPI expression and its function.

Objective To discuss the clinical features of cerebral schistosomiasis. Methods The clinical data of fourteen patients with cerebral schistosomiasis from March 2010 to March 2016 were collected and analyzed retrospectively. Results The schistosomiasis immunological tests of sera and cerebrospinal fluids from the fourteen patients were all positive. Eosinophils increased in ten cases,and the proportion was 5.1％-60.3％. Schistosoma eggs were found in seven cases by the fecal Kato-Katz method. Fourteen cases were all infected with Schistosome japonicum. Twelve cases were diagnosed as chronic type,and two cas-es as acute type. Thirteen patients received medical treatment,of which twelve were cured,and one improved. One patient re-ceived the surgical resection of the lesion. Conclusion The clinical manifestations of cerebral schistosomiasis mainly include seizure,headache,dizziness and fever. In the enhanced head magnetic resonance imaging(MRI),the lesions are clustered and merged into lumps,which is the characteristic image of cerebral schistosomiasis japonica. The praziquantel treatment can achieve a good prognosis.

OBJECTIVETo evaluate the treatment of recurrent acute cholangitis with hepatolithiasis.

METHODSWe retrospectively analyzed the clinical data of patients with recurrent acute cholangitis who were treated in Peking Union Medical College Hospitals emergency department from January 1998 to December 2008.

RESULTSTotally 408 patients underwent surgery, of which 167 patients received emergency operations and 241 underwent selective operations after medication and interventional treatment. The incidence of complications was 6.4% among those who received emergency operations and 3.2% among selective operations. The 30-day mortality rate of selective operations was zero.

CONCLUSIONAlong with the progress of percutaneous cholangiographic drainage and endoscopic retrograde cholangiopancreatography, selective operations have been increasingly applied for acute cholangitis with notably low complications and postoperative death.

OBJECTIVE: To explore the effect and toxicity profile of recombinant human interleukin 11(rhIL-11) on the platelet after hematopoietic stem cell transplantation in patients with leukemia. METHODS: Twenty-four patients with acute or chronic leukemia treated by allogeneic peripheral blood stem cell transplantation (PBSCT) were randomly divided into a test group and a control group. The patients in the test group were treated with rhIL-11 since the 13th day after PBSCT (1.5mg/d),while the control group were given symptomatic treatment. RESULTS: The average time for the platelet to recover to the level of 20 x 10(9)/L was 20.8 days in the test group, and 26.0 days in control group respectively, there was significant difference (P<0.01). The average time for the platelet to recover to the level of 50 x 10(9)/L was 25.7 days in the test group, and 32.3 days in the control group respectively, there was also significant difference (P<0.01). The average time for the platelet transfusion was 2.2 in the test group, 4.1 in the control group, and there was significantly different (P<0.01). The average number of megakaryocytes was 12.2 in the test group, 4.8 in the control group on 30th day after the transplantation,and there was significant difference(P<0.01). The main side effects of rhIL-11 were nausea, vomit, debility, headache, dizzy and pain of injection site, and the degree was all Iapproximately II grade. CONCLUSION rhIL-11 has definite recuperative effect on the recovery of the platelet after PBSCT. There is little side effect, and it can be accepted.
