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.

OBJECTIVETo introduce the application of slender narrow pedicle flap in repairing facial tissue defects after skin carcinoma excision, and investigate its survival mechanism.

METHODSThe slender narrow pedicle iateral maxillocevical flap was designed with its pedicle including skin fascia or only the fascia located in front of auricle or behind of it, repaired 26 cases of facial defects, including 5 temporal skin basal cell carcinoma, 6 skin squamous cell carcinoma, and 1 facial skin malignant melanoma, 8 skin basal cell carcinoma, 5 skin squamous cell carcinoma, 1 skin mucinous carcinoma. In 26 cases, 24 cases their pedicles in front of the auricle, 2 cases behind of the auricle; 4 cases their pedicles only including fascia. The size of the flaps ranged from 3.0 cm x 2.5 cm to 10.0 cm x 8.0 cm. The width and length of the pedicle ranged 1.0-1.5 cm and 2-6 cm.

RESULTS26 cases of the slender narrow pedicle flaps all survived and the results were satisfactory except 5 cases of distal congestion, then gradual recovery.

CONCLUSIONSThis slender narrow flap don't include any major blood vessel, without dissecting the blood vessels in operating. Due to its slender pedicle, the whole flap looks like "pingpang bat", the flap rotation is easy and its coverage area is very large, without cat ears. The postoperative appearance (color, texture, cosmetic aspect) is satisfactory. This slender narrow flap is an extraordinary new flap design and is ideal for the repair of the facial tissue defect after skin carcinoma excision.

OBJECTIVETo compare the morphological difference between dermal tissue of normal skin and that of scar in rat, and to explore its structural pattern.

METHODSThe full-thickness skin and the scar tissue formed 3 weeks after wound healing from SD rats were harvested as samples, which were prepared appropriately afterwards. Samples were scanned and imaged with synchrotron radiation technology, micro-CT, and phase-contrast imaging technology. The images were rebuilt with three-dimensional software.

RESULTSThe micro-CT was materialized by using X-ray generated by synchrotron radiation light source. The structure of dermal tissues was clearly shown with the assistance of phase-contrast imaging technology in the process. It was demonstrated that the dermal tissues of normal skin of rat were mainly composed of collagenous fibers, which twined together to form an olive-like structure. These olive-like structures as basic units were arranged randomly in a certain way. The collagenous fibers in dermal tissue of the scar were arranged in a parallel manner, while some fibers were crooked and arranged in a disorderly manner.

CONCLUSIONSDermal tissue of normal skin in rat has stable three-dimensional structure, and its basic structure and manner of composition are obviously different from those of scar dermal tissue.

OBJECTIVETo evaluate the response rate and adverse reactions of exemestane (a new aromatase inactivator) in the treatment of postmenopausal women with advanced breast cancer.

METHODSOne hundred and seventy-three patients with advanced breast cancer entered this study with two patients excluded because of postmenopausal time being less than one year. Therefore, 173 patients could be evaluated for adverse events and 171 patients could be evaluated for efficacy. Exemestane, 25 mg orally daily for 4 weeks as one cycle was given.

RESULTSIn the 171 patients evaluated for efficacy, 4 (2.3%) experienced a complete response (CR) and 40 (23.4%) a partial response (PR), with the overall response rate of 25.7%. Ninety patients (52.6%) had stable disease (SD), with 25 having SD for at least 24 weeks. The clinical benefit (CR + PR + SD > or = 24 weeks) was shown in 69 (40.4%) patients. Progressive disease (PD) was shown in 37 (21.6%) patients. The untreated patients had a higher objective response rate (33.8%) than the retreated ones (18.1%) with significant difference (P = 0.019 7). The response rates for soft-tissue, bone involvement and visceral metastasis were 32.8%, 23.9%, and 12.4% (P = 0.002). There was no significant difference in different ages, time of menopause, disease-free interval or receptor status (P > 0.05). Drug-related adverse events were gastric discomfort (17.9%), malaise (17.9%), nausea (13.9%), hot flushes (11.0%) and dysphoria (5.8%). Other side reactions and abnormal laboratory parameters were observed occasionally which were irrelevant.

CONCLUSIONExemestane can be used to treat postmenopausal women with advanced breast cancer giving only mild adverse reactions which are well tolerated.

BACKGROUND AND OBJECTIVECT-guided microwave coagulation is a minimally invasive surgery for patients with liver cancer. Total intravenous anesthesia with propofol and fentanyl is commonly used. The depth of anesthesia during microwave coagulation for liver cancer is still monitored by clinical signs. There are few subjective and effective indicators. This study explored the application of Narcotrend-assisted "depth of anesthesia" monitoring on microwave coagulation for patients with liver cancer during total intravenous anesthesia with propofol and fentanyl.

METHODSForty liver cancer patients underwent CT-guided microwave coagulation were randomly assigned to receive Narcotrend index monitoring or standard clinical monitoring for depth of anesthesia with 20 patients in each group. All patients received total intravenous anesthesia with propofol and fentanyl. The depth of anesthesia for patients in the Narcotrend group was measured according to a Narcotrend index, which was maintained between D2 and E0. The depth of anesthesia for those in the standard clinical practice group was measured according to heart rate, mean arterial pressure, and patient movement. Changes of hemodynamics, the duration of the emergence from anesthesia, and the recovery of orientation were recorded. The doses of propofol and fentanyl, postoperative visual analogue scores (VAS), and the incidence of postoperative nausea and vomiting were also recorded.

RESULTSThere was no significant alteration in heart rate or mean arterial pressure between the two groups. Compared with other anesthetic stages, both heart rate and mean arterial pressure decreased during the induction of the anesthesia in the two groups(P<0.05). The doses of propofol were higher in the standard clinical practice group than in the Narcotrend group [(460+/-30) mg vs. (380+/-35) mg, P<0.01]. The duration of emergence and orientation were longer in the standard clinical practice group than in the Narcotrend group [(9.5+/-2.9) min vs. (4.9+/-2.2) min, P<0.01; (12.2+/-3.5) min vs. (6.6+/-3.2) min, P<0.01, respectively]. There was no difference in the dosage of fentanyl, VAS, or the incidence of postoperative nausea or vomiting between the two groups (P>0.05).

CONCLUSIONFor patients with liver cancer, monitoring the depth of anesthesia with Narcotrend on microwave coagulation can contribute to lower dosage of propofol and shorten duration of recovery during total intravenous anesthesia with propofol and fentanyl.

AIM: To observe the anti-oxidative activity and adverse laxative effect of raw, traditional processed and fermented products of Polygoni Multiflori Radix (PMR), and furthermore, to evaluate the fermentation method used in the processing procedure of PMR. METHODS: In vitro ferric reducing antioxidant power (FRAP) assay was carried out to evaluate the anti-oxidative activity. Modulation of normal defecation and effect on gastrointestinal motility in mice were carried out to investigate their adverse laxative effect. RESULTS: Fermented PMR induced less severe laxative adverse effect than Polygoni Multiflori Radix Praeparata (PMRP). PMR fermented with Rhizopus sp. (FB) could modulate the defecation significantly. The gastrointestinal motility was inhibited by PMRP and PMR fermented with Rhizopus oryzae (FA). FA and FB showed better antioxidant activity than PMRP in 50% and 95% ethanol group. Contents of 2, 3, 5, 4'-tetrahydroxy-stilbene-2-O-β-D-glucoside (TSG) were reduced significantly after traditional processing but maintained after fermentation. Emodin and physcion were increased after traditional processing and fermented with Rhizopus oryzae. CONCLUSION All processing procedure, including fermentation, might reduce its anti-oxidative activity. However, most of the processed products could lessen the adverse effect on gastrointestinal tract compared to PMR. Fermentation with Rhizopus oryzae was considered as a promising processing method of PMR.

BACKGROUNDErythromycin-resistant Streptococcus pneumoniae isolates that causing invasive pneumococcal diseases (IPD) in Chinese children remain uncharacterized. This study aims to identify the resistance genes associated with erythromycin resistance and to determine the genetic relationships of IPD isolates in Chinese children.

METHODSA total of 171 S. pneumoniae strains were isolated from 11 medical centers in China from 2006 to 2008. All the isolates were characterized via serotyping and antibiotic susceptibility determination. The erythromycin-resistant isolates were further characterized via ermB and mefA gene detection, multi-locus sequence typing analysis, and pulsed-field gel electrophoresis.

RESULTSA total of 164 (95.9%) isolates showed resistance to erythromycin, of which 162 strains with high high-level resistance (MIC ≥ 256 µg/ml). A total of 104 (63.4%) isolates carry the ermB gene alone, whereas 59 (36.0%) harbor both ermB and mefA genes. Of the 59 strains, 54 were of serotypes 19A and 19F and were identified as highly clonal and related to the Taiwan(19F)-14 clone.

CONCLUSIONSThe erythromycin resistance rate in IPD isolates is significantly high and is predominantly mediated by the ermB gene. Isolates that carry both ermB and mefA genes are predominantly of serotypes 19A and 19F.

OBJECTIVE: To investigate the infection rate of Toxoplasma gondii in patients with hematological diseases. METHODS: The Toxoplasma gondii IgM antibody in 200 patients with hematological diseases were tested, at the same time, IgM antibody in the persons received physical examination and other patients with common clinical diseases also were test, and their detection results were compared. RESULTS: The positive rate of Toxoplasma gondii IgM antibody in patients with hematological diseases was 7.50%, the positive rate in persons received physical examination was 0.67%, and the positive rate in patients with other common clinical diseases was 1.20%. The positive rate of IgM antibody in patients with hematological diseases was statistically significantly higher than that in the latter two kinds of persons(P<0.05). Among the patients with hematological diseases, the positive rate of Toxoplasma gondii IgM antibody in patients with bone marrow neoplastic diseases was 10.32%, which was statistically significantly higher than that in patients with bone marrow non-neoplastic diseases (2.70%). CONCLUSION Patients with hematological diseases are susceptible to Toxoplasma gondii, and to whom enough attention should be paid.
