Objective To evaluate the efficacy of extended-field intensity-modulated radiotherapy (IMRT) in the treatment of patients with early-stage NK/T cell lymphoma (NKTCL),and to examine the clinical characteristics and the effect of treatment factors on the prognosis of these patients.Methods The clinical data of 165 patients with early-stage NKTCL who underwent extended-field IMRT with (n=158,95.8%) or without chemotherapy (n=7,4.2%) were reviewed.Of these 165 patients,140(84.8%) received a radiation dose of ≥50 Gy to the primary lesion,and 25 patients (15.2%) received a radiation dose of<50 Gy.Most patients (n=147,89.1%) were treated with L-asparaginase-based chemotherapy regimens,whereas only 11 patients (6.7%) were treated with doxorubicin-based CHOP/CHOP-like regimens.In addition,109 patients (66.1%) received ≥4 cycles of chemotherapy.Locoregional control (LRC),overall survival (OS),and progression-free survival (PFS) rates were calculated using the Kaplan-Meier method,and the log-rank test was used for survival comparison and univariate prognostic analysis.A multivariate prognostic analysis was performed using the Cox model.Results The 5-year sample size 55.The 5-year OS,PFS,and LRC rates of all patients were 74.2%,72.5%,84.4%,respectively.The patients who received a dose of ≥50 Gy had a significantly higher 5-year LRC rate than those with<50 Gy (91.8% vs.39.7%,P=0.000).The 5-year OS was significantly higher in the low-risk early-stage group than in the high-risk early-stage group (P=0.002).For the high-risk early-stage NKTCL group,patients who received ≥4 cycles of chemotherapy had significantly higher 5-year OS and PFS than those who received<4 cycles of chemotherapy (5-year OS:71.3% vs.59.5%,P=0.032;5-year PFS:70.4% vs.54.4%,P=0.009).In addition,multivariate analysis showed that ECOG≥2,primary tumor invasion (PTI),and Ann Arbor stage Ⅱ were associated with poor OS (P=0.006,0.002,0.014),and ECOG≥2 and PTI were associated with reduced LRC (P=0.004,0.016).Furthermore,ECOG≥2,PTI,Ann Arbor stage Ⅱ,and extranasal primary site were associated with lower PFS (P=0.045,0.003,0.030,0.032).Conclusions Extended-field IMRT at a dose of ≥50 Gy can lead to favorable LRC,OS,and PFS in patients with early-stage NKTCL.However,it is less effective against distant early-stage NKTCL in patients with poor prognosis.Nevertheless,≥4 cycles of chemotherapy can significantly improve the OS and PFS of patients with early-stage NKTCL.

BACKGROUNDTo study oxidative stress in patients with chronic hepatitis B.

METHODSMalondialdehyde (MDA), total anti-oxidative ability and ascorbic acid were measured as markers of oxidative stress in 30 patients with chronic hepatitis B, besides HBV DNA and ALT.

RESULTSMDA was significantly higher in patients with hepatitis B than the controls (P less than 0.05). Ascorbic acid was significantly higher in patients with normal ALT than the controls (P less than 0.01). MDA was significantly higher in patients with increased ALT than the controls and in patients with normal ALT. MDA was significantly positively correlated with ALT (r=0.61), and ascorbic acid was significantly negatively correlated with ALT (r=-0.64) in patients with hepatitis B. No significant relationship was found between HBV DNA and other indices of oxidative stress. No significant difference in total anti-oxidative ability was found among all groups.

CONCLUSIONThere was a disturbance between oxidative stress and anti-oxidative ability in patients with chronic hepatitis B. In patients with increased ALT, oxidative stress became high. In patients with normal ALT, oxidative stress level was low. The indices of oxidative stress should be detected in patients with hepatitis B, in addition to HBV markers.

The lumbar disc herniation is a common and recurrent disease in the department of orthopedics. At present, the treatment means mainly include conservative treatment and surgical treatment. Compared with traditional open surgery, percutaneous transforaminal endoscopic discectomy (PTED) is safe, effective, economical and minimally invasive. It is widely used in minimally invasive treatment of lumbar disc herniation. However, the clinical reports of the failure of PTED are also common. According to the research reports of domestic and foreign scholars, there are varieties of risk factors for surgical failures, including the selections of patients, indications, surgical approaches and anesthesia methods preoperative. Occurrences of surgical complications including infection or left pains, and reasonable rehabilitation exercise after the operation are related to failures. There is no unified conclusion at present. In this paper, we reviewed the literatures about failed PTED, and try to make an overview about the general situation of failed operation in clinical practice, the risk factors for failures and the countermeasures.

Breast cancer has the highest incidence rate among all women's malignant tumors worldwide.Surgery,radiotherapy and chemotherapy are three major treatments,while most patients showed adverse effects or complications during or after the treatment,including lymphedema,gastrointestinal reactions and leukopenia,which cause severe impact on patients' recovery and quality of life.Moxibustion has been used and certified to alleviate adverse effects of surgery or chemoradiotherapy for breast cancer.We have summarized literatures in recent years and suggest more systematic research in the future for the underlying mechanism.

OBJECTIVETo study the impact of abdominal obesity on the production of male reproductive endocrine hormones.

METHODSThis study included 342 male patients at the andrology clinic, aged 19 -47 years and higher than 160 cm. We measured their waistlines, hiplines and waist-hip ratio, detected the levels of serum estradiol (E2), testosterone (T), follicle-stimulating hormone (FSH), luteinizing hormone (LH) and free testosterone (FT) by chemiluminescence and radioimmunoassay, and analyzed the correlation of the waist-hip ratio with the levels of reproductive endocrine hormones. Abdominal obesity was defined as the waist-hip ratio > 0.9.

RESULTSIn the 342 male patients, there were 62 cases of abdominal obesity and 280 cases of the normal somatotype (waist-hip ratio < or = 0.9). The waist-hip ratio was negatively correlated with the T level (r = -0.163, P = 0.003) and the T/LH ratio (r = -0.13, P = 0.02). Both the T level and T/LH ratio were significantly reduced in the abdominal obesity patients ([14.51 +/- 4.53] nmol/L and 2.26 +/- 0.36) as compared with the normal somatotype controls ([17.21 +/- 4.23] nmol/L and 4.61 +/- 0.19) (P < 0.05).

CONCLUSIONThe waist-hip ratio has a significant negative correlation with the T level and T/LH ratio, and the serum T level is significantly lower in men with abdominal obesity than in those of the normal somatotype.

OBJECTIVETo compare the effect between lumbar backwards flexion manipulation and rotating manipulation for treating lumbar intervertebral disc herniation.

METHODSTwo hundred and nine patients of lumbar intervertebral disc herniation, male 131, female 78, the age from 20 to 79 years old, 58 cases of all these patients age above 50. According to diagnosis the ladder of the 92 cases bulging type, 69 hernia type, 48 cases free type. The patients were randomly divided into treatment group (107 cases) and control group (102 cases). All the patients were treated with the three-dimensional computer-controlled traction therapeutic apparatus, with continued traction for 30 minutes. After traction, lumbar backwards flexion manipulation and rotating manipulation were respectively adopted in treatment group and control group (on alternate days one time, 3 times as a course of treatment). The symptoms and signs (including back pain and discomfort, lower limb pain and numbness, powerless urination and defecation, numbness in perineum, straight-leg raising degree, ability of lower extremity walking, work and live) of patients were observed after treatment.

RESULTSAll the patients were followed up from 1 to 6 months with an average of 3.2 months. After treatment, the symptoms and signs of patients have markedly improved (P < 0.01), but the lower back pain and discomfort, lower limb walking ability in treatment group were better than control group (P < 0.05). According therapeutic criteria, the effect of treatment group was better than of control group (P < 0.01). In cases with bulging type, 47 in treatment group and 45 in control group, the effect of treatment group was better than of control group (P < 0.05); in cases with hernia type, 35 in treatment group and 34 in control group, there was no significantly difference in effect between two groups (P > 0.05); in cases of free type, 25 in treatment group and 23 in control group, there was no significantly difference in effect between two groups (P > 0.05).

CONCLUSIONThe global effect of lumbar backwards flexion manipulation was satisfactory than rotating manipulation for treating lumbar intervertebral disc herniation. But rotating manipulation suited to free type.

BACKGROUNDMore and more Chinese drink hot water from water dispensers while many children were scalded due to this change. The present study aimed to propose a feasible strategy for prevention.

METHODSA retrospective study was conducted for all water dispensers related pediatric burns admitted to Changhai Hospital from January 2005 to December 2009.

RESULTSThe number of new cases and incidences of pediatric burns due to hot water from water dispensers was significantly increasing year after year. In the total 238 involved cases, 175 cases happened on males and 78.9% were at the age of 1 - 4 years. The burn areas were mainly located in upper extremities. All water dispensers in the surveyed families had no isolate protection devices and 85.2% of their locations were easy for children to reach. Nearly half of the children were in the same room with their guardians when injured. Total 196 burned children were playing the taps of water dispensers before injured, unfortunately, 80.6% of them have not been stopped until burned.

CONCLUSIONAs the kind of burns is quite serious and with bad outcome, some recommendations should be followed, such as buying water dispensers with protection devices, keeping children from touching them and so on.
