Background and purpose: Sorafenib hepatocellular carcinoma assessment randomized protocol (SHARP) and sorafenib in patients in Asia-Pacific region with hepatocellular carcinoma (ORIENTAL) had indicated that multi-kinase inhibitor sorafenib could prolong overall survival (OS) and time to progression (TTP) as well as improve progress free survival (PFS) in patients with advanced stage hepatocellular carcinoma. Drug-related adverse events in the course of treatment restricted its clinical application to a certain degree. This study was aimed to summerize the adverse events as well as the management of sorafenib in our clinic. Methods: Twenty-five cases clinically diagnosed as advanced hepatocellular carcinoma were enrolled from January 2008 to October 2009. All the patients who received sorafenib treatment met inclusion criteria as followed: (1) Progression of disease after trans-hepatic arterial chemoembolization therapy; (2) Extensive portal vein cancerous thrombus formation; (3) Portal zone or retroperitoneal lymph node metastasis or multiple remote metastasis, such as lung or bone; (4) Diffused poor blood supply to tumor; (5) Inform consent was obtained. All adverse events with different grade were observed during the beginning 12 weeks, and clinical treatment were carried out relatively. Results: Total of 25 cases were enrolled. Nine patients died of the disease, 3 of them died during the first 12 weeks, 3 patients abandoned sorafenib treatment, among them 2 died before the finish of 12 weeks treatment and 1 patient discontinued 5 months after the sorafenib treatment. Twenty cases finally assigned. Number of patients encountered drug-related adverse events were: HFSR (hand-foot-skin-reaction) 4(4/20), diarrhea 4(4/20), alopecia 5(5/20), rasb 4(4/20), fatigue 8(8/20), leukopenia and Thrombocytopenia 4(4/20), elevated blood pressure 1(1/20) and abdominal pain 1(1/20). After clinical management, 20 patients' sorafenib treatment were eventually not affected by adverse events. Conclusion: Sorafenib was well-tolerated and is a safe option of treatment for patients with advanced hepatocellular carcinoma.

Objective:To explore the cytogenetic characteristics of hypospadias in children by karyotype analysis.Methods:From June 2008 to May 2018, 45 children with hypospadias in Tianjin Children's Hospital had cytogenetic abnormalities. Their median age was 10 months(range 3 hours to 5 years old). Of the 45 cases, 20 were proximal hypospadias, 1 was middle hypospadias. All 24 cases had varying degrees of genitourinary malformations. Among them, 15 cases had unilateral or bilateral cryptorchidism, 5 cases had scrotal division, 3 cases had penile scrotal transposition, 3 cases had small penis, 3 cases had indirect inguinal hernia, 1 case had repeated urethra, 1 case had hydrocele and 1 case had concealed penis. To the other systemic malformations, there was 1 with cleft lip and palate and 1 with congenital heart disease. G-banding karyotype analysis of peripheral blood lymphocytes was performed in all 45 cases.Results:Among the 45 cases of hypospadias with abnormal karyotypes, with an abnormal rate of 14.0%, 28 cases (62.22%) had sex chromosome abnormalities, including (47, XXY), (46, XX/47, XXY), (45, X0/47, XYY), etc. Sexual inversion occurred in 8 cases (17.78%), all of which were 46, XX. There were 4 autosomal abnormalities (8.89%), including (46, XY, 9p+ ), (46, XY, 10p+ ) and (46, XY, 1q+ ). Chromosome polymorphism was found in 4 cases (8.89%), including [46, XY, inv(9)] and [46, XY, 16qh+ ], and the equilibrium translocation of 1 case (2.22%) was [45, XY, -21, -22, + t(21; 22)]. Among the 45 cases, 8 sex reversal children with (46, XX) chromosome karyotype were all proximal hypospadias.Conclusions:Children with hypospadias may be associated with chromosomal karyotype abnormalities, including sex chromosomal abnormalities, autosomal abnormalities, chromosome polymorphism and balanced translocation. Among them, sex chromosome abnormality was the most common and balanced translocation was the least.

Point Dingchuan (Ex-B1) pertains to extraordinary points and often produces a good therapeutic effect on respiratory system diseases. Ancient Chinese medical books do not record point Dingchuan. Modern Chinese medical textbooks describe the location and efficacy of and indications for this point but do not state their provenances. In order to further popularize the clinical application of point Dingchuan, this article verifies the origin and development of the name and location of point Dingchuan so as to provide a certain reference for clinically correct selection and use of this point. The results show that point Dingchuan followed the course of development from ashi point to new point and then to extraordinary point. The development of point Dingchuan to the same acupoint name and location as now international use went mainly through four stages, that is, similar name and different location, similar name and location, same name and different location, and same name and location.

OBJECTIVETo study changes of left ventricular remodeling (LVR) in hypertension patients with carotid atherosclerosis (CAS) of phlegm-dampness syndrome (PDS).

METHODSDoppler ultrasonography data of CAS were observed in 223 hypertension patients with CAS (as the hypertension group, including 119 patients of the PDS group and 104 of the non-PDS group), 81 CAS patients with non-hypertension, and 19 non-hypertension non-CAS patients (as the control group). The difference in the degree of LVR was compared among the above groups.

RESULTSThe left ventricular posterior wall thickness (LVPWT), inter ventricular septum thickness (IVS), E/A were higher in the hypertension group than in the non-hypertension group (P < 0.05). The left ventricular end-diastolic dimension (LVEDD), left ventricular end-systolic diameter (LVESD), stroke volume (SV) were higher in the soft plaque hypertension group and the soft plaque non-hypertension group than in the hard plaque group, the thickening intimal group, and the normal intimal group (P < 0.01 , P < 0.05). The LVEDD, LVESD, and SV were higher, and the ejection fraction (EF) was lower in the PDS hypertension group than in the non-PDS hypertension group (all P < 0.05). Of them, LVEDD, LVESD, and SV were higher in the soft plaque group than in the hard plaque group (P < 0.01), the thickening intimal group (P < 0.01) and the normal intimal group (P < 0.05). There was no statistical difference in PDS hypertension between the soft plaque group and the hard plaque group (P > 0.05).

CONCLUSIONThe hypertension patients with CAS of PDS might be correlated to LVR, and LVR was more obviously in the soft plaque patients.

Objective: To investigate the relation between ser um hyaluronic acid (HA) concentration and cryopreservation-reperfusion injury. Methods: The animals were randomly assigned to 3 groups: (1 ) group A: the control; (2) group B: liver allografts were stored in lactated R inger's solution (0℃) for 2 h before implantation; (3) group C:liver allografts were stored in lactated Ringer's solution (0℃) for 4 h before implantation. Th e serum sample and liver specimen were taken up at 2 h and 4 h after transplanta tion to detect the concentration of HA, AST and LDH, and to get pathologic obser vation. Results: Serum HA increased earlier and decreased more s hortly than AST and LDH after transplantation in group A. Serum HA increased sig nificantly in group B and C, much higher than that in group A(P<0.01). The i njury of vascular endothelium and the disorder of hepatic sinuses and hepatic lo b ules were observed in group B and C. In the specimen of 4 h in group C, evident infiltration of inflammatory cell was present. Conclusion: Cryopreservation leads to injury of endothelial cell and reperfusion aggravat es this injury. The serum HA concentration indicates the degree of cold ischemia -reperfusion injury.

OBJECTIVETo explore the therapeutic effects of posterior osteotomy and long-segment internal fixation in the treatment of senile thoracolumbar kyphotic deformity and provide the reference for operative treatment.

METHODSFrom April 2007 to April 2010, 19 older patients with thoracolumbar kyphotic deformity were respectively analyzed. There were 12 males and 7 females with an average age of 62 years (ranged, 58 to 74 years). Among patients, 11 cases were old fracture, 3 cases were ankylosing spondylitis, and 5 cases were old spinal tuberculosis. According to preoperative Frankel classification, 12 cases were grade E, 4 cases were grade D, 2 cases were C and 1 case was grade B. All patients were treated by posterior osteotomy and long-segment internal fixation and followed up above 1 year. VAS score preoperative, 2 weeks and 1 year after operation, Cobb's angle,n erve function and complication were observed.

RESULTSVAS score preoperative, 2 weeks and 1 year after operation separately was (7.0 +/- 1.2),(1.1 +/= .7) and (1.3 +/- .8); while Cobb's angle separately was (44.1 +/- .9), (10.9 +/- .1) and (11.5 +/- .8); there was significant difference in VAS score and Cobb's angle between preoperative and 2 weeks after operation (P < 0.05) w hile no significant difference between 2 weeks and 1 year after operation (P > 0.05). Eighteen cases met the standard of osseous fusion, 1 case occurred nonunion, but not looseness 1 year after operation. Nerve function: 3 cases changed grade E from 4 cases with grade D, 2 cases with grade C changed to grade D, 1 case with grade B changed to grade

CONCLUSIONPosterior osteotomy and long-segment internal fixation for the treatment of senile thoracolumbar kyphotic deformity can receive a good short-time effects.

OBJECTIVETo facilitate early recognition of ominous clinical manifestations, to understand pathophysiology and assess treatment effects in patients with severe enterovirus 71 (EV71) associated hand, foot and mouth disease (HFMD).

METHODA retrospective analysis was performed based on the clinical records, laboratory data and treatment effects which were collected from twelve severe EV71 infected cases from nine hospitals in 2008, in Hubei province, China.

RESULTOf the 12 severe cases, ten (83.3%) were male and two female. The median age was 1.96 yrs (8 m to 7 yrs). The mean hyperthermic duration was 6 days with the peak temperature over 38.5 degrees C, and mean rash duration was 7 days. Fever and rash emerged simultaneously in 4 of 5 cases with cardiopulmonary failure. The severe complications included encephalitis (10 cases), pulmonary edema or hemorrhage (5 cases). Eleven cases were checked with magnetic resonance imaging (MRI) and four cases showed characteristics of encephalitis or meningitis, two with images of naso sinusitis and ethmoid-mastoid inflammation. Chest X-ray examination showed with pulmonary edema on single or both sides (5 cases), bronchitis (4 cases), and normal image (3 cases). There was no specific finding in the cardiac ultrasound and electrocardiogram in any of the patients, as well as the white blood cell count, blood glucose, prothrombin time, partial thromboplastin time and D-dimer. Cerebrospinal fluid showed aseptic meningitis with the increase of cell count in 7 cases. All patients were treated with antibiotics and/or antivirals, such as cephalosporins, ribavirin etc. Eleven patients were treated with intravenous immunoglobulin (total dose 2 - 4.5 g/kg) for 2 - 5 days, and the highest blood concentration of immunoglobulin was detected increasing at 7 g/L. Seven cases were also treated with methylprednisolone 10 - 30 mg/(kg x d), four with dopamine, dobutamine, or digitalis. In addition, by using continuous positive airway pressure by nasal catheter and maintenance of circulation in the cases with cardiopulmonary failure could not relieve the symptoms of dyspnoea, and mechanical ventilation was required to maintain for a mean of 72 hrs (24 - 96 hrs). Except one case died of pulmonary edema in the early stage, others were cured without sequelae.

CONCLUSIONSevere EV71 infection is more common in children younger than 3 years old, in which the profound complications include encephalitis and pulmonary edema. The mechanical ventilation should be critically urged for child with complicating cardiopulmonary failure as soon.

OBJECTIVETo evaluate the impact of neoadjuvant chemoradiation on perineal wound healing following abdominoperineal resection(APR) for lower rectal cancer.

METHODSData of 93 patients who underwent APR for low rectal cancer between January 2005 and January 2009 in Peking Union Medical College Hospital were reviewed, including patients who received neoadjuvant chemoradiation (n=29) and those undergoing surgery alone(n=64). Perineal wound healing was the primary outcome measurement. Condition of wound healing was classified as good, moderate, and poor and was compared between the two groups.

RESULTSTwenty nine patients in the neoadjuvant group received preoperative regional radiation(50 Gy, 25 fractions/5 weeks) with synchronous FOLFOX4 chemotherapy(fluorouracil and oxaliplatin). In the neoadjuvant group, wound healing after APR was good in 18 patients(62.1%), moderate in 6(20.7%), and poor in 5(17.2%). In patients who had surgery alone, wound healing after APR was good in 41 patients(64.1%), moderate in 15(23.4%), and poor in 8(12.5%). There was no significant difference in the incidence of wound infection(poor wound healing)between the two groups(P=0.773).

CONCLUSIONNeoadjuvant chemoradiation therapy is not associated with increased perineal wound infection following abdominoperineal resection for low rectal cancer.

OBJECTIVETo investigate the relationship between gene polymorphism of CYP2E1, CYP1A1, IL-4 and susceptibility of medicamentosa-like dermatitis induced by trichloroethylene (TCE).

METHODS35 patients with medicamentosa-like dermatitis induced by TCE were chosen as the patient group, and 35 healthy workers as control group. The real-time quantitative polymerase chain reaction (PCR) with TaqMan minor groove binding (MGB) probes was used to test single nucleotide polymorphisms (SNP) of CYP2E1, CYP1A1 and IL-4 in the patients with medicamentosa-like dermatitis as well as in the control. The genotypes and the frequency of genotype or allele were compared between the patients and control with statistical analysis.

RESULTSThe frequency of allele G within CYP1A1 gene (rs1048943) was significantly higher in TCE patients (37.1%) than that in control (P<0.05); the frequency of allele T within CYP2E1-1053 C/T was significantly higher in TCE patients (41.4%) than that in control (P<0.01); the frequency of T/T within IL-4-588 C/T (rs2243250) was significantly higher in TCE patients (75.0%) than that in control (P<0.01), and the frequency of allele T within IL-4-588 C/T (rs2243250) was also significantly higher in TCE patients (87.5%) than that in control (P<0.01).

CONCLUSIONThe gene polymorphism of CYP2E1, CYP1A1, IL-4 is probably associated with hypersensitivity for the TCE patients with medicamentosa-like dermatitis, and could be one of the genetic factors related to the individual susceptibility to TCE exposure.

Cellular therapy in acute ischemic stroke (AIS) is a research hotspot in the field of neu-roscience in recent years. Compared with other cells,bone marrow mononuclear cells (BMMNCs) are one of the most attractive therapeutic cells because BMMNCs can be rapidly isolated from bone marrow,are enriched with stem cells and permit autologous applications. Numerous basic researches showed that BMMNCs trans-plantation can decrease infarct volume and promote neurological outcomes in animal stroke model,indicating BMMNCs transplantation may has therapeutic values in acute ischemic stroke,and the transformation from basic research to clinical applications is on the key phase. In this paper,the progress of BMMNCs transplan-tation is reviewed in acute ischemic stroke on the aspects of BMMNCs component,methods of purification, route of transplantation,therapeutic mechanisms and problems from basic research to clinical application.
