AIM To investigate the effect of paeonol on proliferation and apoptosis of K 562. METHODS The inhibitory effect of paeonol on K 562 cells proliferation was assayed by MTT dye reduction. HE staining were used to observe the morphology of apoptotic cells, and Flow cytometric analysis were also used to analyze the K 562 apoptosis. RESULTS Pae at the concentration of 7.81～250 mg?L -1 significantly inhibited proliferation of K 562 cells in dose-dependent manner. Typical apoptotic changes were observed in K 562 cells under the light microscope. By FCM methods, the apoptotic rates of K 562 cells were increased from 10.01% to 34.16% after treatment of Pae at concentrations from 7.81 to 125 mg?L -1 for 24 h, which showed obvious concentration-effect relationship. The apoptotic rates of K 562 cells were also increased when Pae (6.25, 25 and 100 mg?L -1) was treated for 6, 12 and 24 h, which showed obvious time-effect relationship. CONCLUSION Paeonol may inhibit K 562 cell proliferation and induce its apoptosis.

OBJECTIVETo study operative effects for the treatment of multiple ligament injuries of knee joints.

METHODSFrom 2008 to 2013, 26 patients (17 males and 9 females) with multiple ligament injuries of knee joints were treated surgically. The average age was 40.7 years old, ranging from 29 to 55 years old. All the patients were treated with arthroscopic reconstruction of cruiate ligament with autogenous or allogeneic hamstrings and tendon, and at the same time received repair of medial collateral ligament and lateral collateral ligament, as well as the treatment of exterior and interior complex injuries. Nine patients received second stage operation after the initial operation for mistake or missed diagnosis, and other patients were treated at the first stage. The Lysholm scoring system was used to evaluate function and stability of knee joints before and after operation.

RESULTSAll the patients were followed up for an average duration of 1.6 years (ranged, 0.8 to 3.2 years). The mean awaiting time for operation was 1.2 months. The Lysholm score was improved from preoperative 42.5 +/- 4.5 (ranged, 33 to 48) to the latest follow-up 78.1 +/- 3.9 (ranged, 57 to 95). The function of knee joint was improved obviously in the arthroscopic reconstruction patients, with joint range of motion exceeding 900 and with Varus & Valgus tests near to normal. All the patients had negative findings in the Lachman test at 70 degrees of flexion.

CONCLUSIONArthroscopic reconstruction should be the first choice in treating multiple ligament injuries of knee joints. If the anterior and posterior cruciate ligament injuries can't be treated simultaneously, the posterior cruciate ligament injuries should be treated preferentially at the first stage and the anterior cruciate ligament injuries should be treated at the second stage. The diagnosis of posterior cruciate ligament is easy to be missed.

Chinese patent medicine with double identity was a special phenomenon, and many preparations not only were prescription drugs but also over the counter ( OTC) drugs, which brought a lot of trouble. Based on statistics of list of OTC medicines of CFDA, related varieties, route of administration and functions of these drugs were searched. The causes of insufficient were analyzed and the potential risk was investigated. To ensure the safety of drug usage for the patient, risk management system should be set up by improving the technical requirements for registration, improving the drug labels and manuals, playing the role of pharmacists in pharmacy services and raising awareness of doctor and patient for these drugs.

The study was purposed to investigate the differentiation ability of mesenchymal stem cells (MSCs) into myocardial cells in vitro. Rat bone marrow-derived MSCs were labeled and co-cultured with neonatal rat cardiomyocytes (CM) for 5 - 7 days. The expression of cell surface antigens was detected by flow cytometry, and the expression of muscle-specific marker myosin and troponin T in labeled cells was detected by immunofluorescence. The results showed that in vitro cultured MSCs expressed CD90, CD44, CD105, CD54, not expressed CD34, CD45, CD31. After co-cultured with neonatal rat CM, labeled MSCs differentiated into cardiomyocyte-like cells expressing myosin and troponin T. It is concluded that MSCs can differentiate into cardiomyocyte-like cells when co-cultured with neonatal myocardial cells in vitro. In co-culture of two kind of cells in ratio of four to one showed obvious efficacy differentiating MSCs into CMs.

OBJECTIVETo evaluate the efficacy of allogeneic hematopoietic stem cell transplantation (allo-HSCT) for aplastic anemia (AA).

METHODSTwelve patients with severe AA (SAA) and 4 with chronic AA (CAA) received allo- HSCT. The effectiveness and complication were analyzed retrospectively.

RESULTSHematopoiesis reconstitution was achieved 14 patients (87.50%). The median time of neutrophils reached to 0.5 x 10(9)/L and platelets reached to 20 x 10(9)/L were 14 (11 - 16) and 14 (10 - 33) days, respectively. Six cases developed grade I - II acute graft-versus-host disease (aGVHD), chronic local GVHD occurred in 2 patients. Graft rejection occurred in 3 cases. Thirteen cases survived with a median of 10 (0.5 - 84) months at the end of follow-up. Three cases died of un-engraftment, graft rejection (GR) and interstitial pneumonia (IP) each.

CONCLUSIONAllo-HSCT is an effective therapy for patients with AA. Enhancing immunosuppressive treatment for conditioning and GVHD prophylaxis may reduce the incidence of GR and GVHD.

Objective To observe the circadian rhythm of blood pressure and investigate the impact of Norvasc and Tanatril administrated at different time points based on the theory of time therapeutics in hypertensive patients. Methods The 24-hour ambulatory blood pressure was monitored in 130 inpatients and outpatients with grade 3 or 2 hypertension from May 2008 to November 2009. A total of 34 dipper hypertensive patients were grouped into dipper blood pressure group and 5 mg/d of Norvasc and Tanatril were taken by them at 6:00 AM. A total of 96 nondipper hypertensive patients were further divided into three subgroups after adjustment for age and gender: 5 mg/d of Norvasc and Tanatril were taken by group I (n = 30) at 6:00 AM; 5 mg/d of Tanatril at 6:00 AM and 5 mg/d of Norvasc at 18:00 PM by group Ⅱ (n = 32); 5 mg/d of Norvasc at 6:00 AM and 5 mg/d of Tanatrilat 18:00 PM by group Ⅲ(n=34).The 24-hour ambulatory blood pressure monitoring was performed again after four weeks treatment and 24-hour mean systolic blood pressure(24 hSBP),24-hour mean diastolic blood pressure(24 hDBP),daytime and nighttime mean systolic blood pressure(dSBP,nSBP)and daytime and nighttime mean diastolic blood pressure(dDBP,nDBP),were analyzed.Results The 24 hSBP,24 hDBP and dSBP,and dDBP were reduced from(154.3±5.6),(95.4±3.1),(158.7±6.5),(99.6±3.7)mmHg to(137.2±3.9),(82.5±2.7),(139.7±3.8),(85.2±3.5)mmHg,respectively,in dipper blood pressure group(t=2.124,2.356,2.278,2.449,all P<0.05).The 24 hSBP and 24 hDBP of the three groups in nondipper blood pressure were decreased from(154.4±6.1),(156.7±6.7),(156.6±5.2),(95.8±2.8),(94.9±3.8),(95.7±3.2)mmHg to (139.6±4.1),(134.5±4.6),(133.4±3.5),(83.5±4.2),(80.8±5.6),(81.6±4.7)mmHg,respectively(t=2.038,2.040,2.135,2.142,2.213,2.216,all P<0.05).dSBP and dDBP were decreased from(158.6±3.50),(158.4±5.6),(159.5±4.),(98.4±3.7),(99.6±3.7),(83.9±5.2)mmHg to(138.9±5.4),(136.7±4.1),(137.4±6.4),(85.8±5.3),(83.6±5.1),(83.9±5.2)mmHg,respectively(t=2.021,2.252,2.261,2.217,2.167,2.076,all P<0.05).nSBP and nDBP were decreased from(146.7±6.9),(149.8±3.9),(150.2±4.1),(93.7±4.2),(95.7±4.3),(93.4±3.3)mmHg to(133.7±4.6),(129.8±5.7),(127.6±2.8),(87.8±2.9),(78.5±6.4),(77.8±4.8)mmHg,respectively(t=1.798,2.032,2.014,1.864,2.157,2.166,all P<0.05).There were significant differences in nSBP and nDBP among all groups after treatment(F=2.32,2.17,all P<0.05),and the effect of the drugs was better in groug Ⅱ and Ⅲ than in group Ⅰ(q=3.17,4.03,3.32,4.19,all P<0.05),but there were no significant differences between group Ⅱ and Ⅲ(P>0.05).Conclusions Blood pressure can be controlled effectively by taking two antihypertensive medictions in the morning in hypertensive dipper patient but the blood pressure of nondipper hypertensive patients were able to be controlled more efficiently by taking the two antihypertensive medictions separately in the morning and at the evening compared with that taking the two drugs together in the morning.

Objective: To investigate the prevalence and associated factors of eczema in children in order provide reference for the prevention and treatment of eczema. Methods: Two primary schools in a district of Shenyang were randomly selected to conduct a questionnaire survey on 2 240 students in May 2017. Children with eczema need to be diagnosed by a doctor. Results: There were 838 cases of eczema with a reported rate of 37.4%, 38.7% in boys and 36.1% in girls. The age of 6 to 12 months was the peak period of first eczema in children, and the proportion of eczema within 1 year was up to about 70%. Children who have had eczema in the past were now more likely to catch a cold, and the reported rates of allergic rhinitis, asthma and food allergies were also significantly higher. The Logistic regression analysis showed that the mother was unhappy during pregnancy(OR=1.32,95%CI=1.03-1.69), the parents were more educated (OR=1.60, 95%CI=1.19-2.16), and the parents were allergic (OR=1.58,95%CI=1.07-2.33；OR=1.41, 95%CI=1.02-1.94), family history of diabetes(OR=1.95, 95%CI=1.41-2.68), and cesarean(OR=1.33, 95%CI=1.07-1.65) were risk factors of eczema in children. Conclusion The incidence of children eczema is affected by maternal mood during pregnancy, family factors and delivery mode. It is of practical significance to prevent children eczema in early development for reducing the incidence of other allergic diseases in the future.

OBJECTIVE: To evaluate the clinical effects and characteristics of combined transperineal and transpubic urethroplasty for patients with complex pelvic fracture urethral distraction defect (PFUDD). METHODS: We retrospectively reviewed the clinical data of 17 male patients with complex posterior PFUDD from January 2010 to December 2019. The complications included urethrorectal fistulas in 2 patients (11.8%), urethroperineal fistula in 1 patient (5.9%). Ten patients had undergone previous treatments: dilatation in 3 patients (17.6%), internal urethrotomy in 1 patient, failed urethroplasty in 6 patients (35.3%), of whom 2 patients had two times of failed urethroplasties. All the patients were performed with urethroplasty by combined transperineal and transpubic approach with removing the entire pubic bone followed by the anastomosis. RESULTS: The mean age of the patients included in this study was 35.5 (range: 21-62) years. The mean length of stricture was 5.5 (range: 4.5-7.0) cm, the mean follow-up was 27 (range: 7-110) months, the mean time of operation was 190 (range: 150-260) min, the mean evaluated blood loss was 460 (range: 200-1 200) mL. There were 5 patients who needed blood transfusion intraoperatively or postoperatively. Wound infection was seen in 4 out of 17 patients and thrombosis of lower extremities in 1 out of 17 patients. The last follow-up showed that the mean postoperative maximum urinary flow rate was 22.7 (range: 15.5-40.7) mL/s. After removing the catheter, one patient presented with decreased urinary flow and symptoms of urinary infection. Cystoscopy showed the recurrent anastomotic stricture, which was cured by internal urethrotomy. In our series, the success rate of the combined transperineal and transpubic urethroplasty was 94.1% (16/17). CONCLUSION Combined transperineal and transpubic urtheroplasty can achieve a tension free anastomosis after removing the entire wedge of pubis in some patients with complex PFUDD. However, this procedure should be completed in a regional referral hospital due to the complexity of the operation and the high percentage of complications.
