As the basis of the health management of the elderly, weight management should receive attention from medical practitioners.However, there is an ongoing debate on the ideal range of body mass index for elderly in China.This article aimed to find the suitable body mass index for Chinese old people by reviewing the literature regarding the body mass and obesity of the elderly.Lots of evidence show that overweight and mild obesity appear to be the optimal weight status for the elderly.

Objective To investigate the differences of four equations to estimate glomerular filtration rate (GFR) and their impacts on chronic kidney disease (CKD) prevalence in communitydwelling elderly people in Beijing.Methods A total of 489 participants aged above 70 years were enrolled.The GFR was estimated using the Cockcroft Gault (CG) equation,Chronic Kidney DiseaseEpidemiology Collaboration (CKD-EPI) equation,Modification of Diet in Renal Disease (MDRD) equation and Berlin Initiative Study (BIS) equation respectively.The internal-consistency check was made on the four equations for the GFR (ml min 1 1.73m 2) estimates.Results The mean age of participants was (81.8±7.6) years.The mean GFR estimated using the CG,CKD-EPI,MDRD and BIS equation was 58.4± 17.2,71.9± 15.3,76.7± 19.1 and 62.7± 12.7,respectively.And the prevalence of CKD was 56.2％,22.7％,17.8％ and 41.7％,respectively.The greatest differences of equations to estimate GFR were seen in elderly people aged 90 and above,and those with body mass index＜ 20.0 kg/m2 or serum creatinine concentration＜ 88.4 μmol/L.Conclusions The GFR estimated using different equations has a large difference which has a significant effect on CKD classification in elderly people.The equation to estimate GFR for the elderly is urgently needed.Until then,the eGFR and CKD classification estimated using different equations should be regarded with caution.

Objective To investigate CT and MRI imaging of Warthin tumor of parotid gland.Methods CT and MRI character-istics of 5 1 patients confirmed as Warthin tumor by operation and pathology were analyzed retrospectively.Results Among 5 1 cases, 43 patients were males,and 8 patients were females.A total of 84 lesions were found in all cases,20 cases had at least 2 lesions.The margins of lesions were well-defined.68 lesions were round or elliptical.45 lesions located in the posterior and inferior quadrant of the parotid gland completely or premodinantly.The density and signal of most lesions were homogeneous.The parenchymal area of most lesions showed an early moderate-remarkable enhancement.Small blood vessels surrounded the lesions in 1 9 cases.Conclusion CT and MRI are important and valuable for the diagnosis of Warthin tumor.

Objective To determine whether the different pathological types of astrocytic tumours can be differentiated by diffusion tensor MR imaging. Methods In this study, diffusion tensor MR imaging was performed preoperatively in 67 patients with different pathological types of astrocytic tumours. Furthermore , T1WI, T2WI, FLAIR and T1WI enhancement scanning by GD-DTPA were performed preoperatively in all patients. The Mean diffusivity (ADC) values in the tumor parenchyma and normal white matter from different pathological types of astrocytic tumours were measured and analyzed. The ADC with the tumor parenchyma and normal white matter from the tumours were statistically analyzed by SPSS 19.0. The results were expressed as ± s and P < 0.05 was regarded as statistically significant differences. Results There were many differences with ADC (< 10-9 mm2/s) in the tumor parenchyma between fibrillary astrocytoma (1.48 ± 0.12、0.72 ± 0.05) from fat cell astrocytoma (1.31 ± 0.07, 0.69 ± 0.03), There were also many differences with ADC ( < 10-9 mm2/s) in the tumor parenchyma between fibrillary and fat cell astrocytoma from anaplastic astrocytoma (1.06 ± 0.11, 0.71 ± 0.04) and giant cell glioblastoma (0.98 ± 0.09, 0.73 ± 0.04). There were not differences with ADC in the tumor parenchyma between anaplastic astrocytoma from giant cell gliobastona. Conclusion Measurement of tumor parenchyma′s ADC values can identify different pathological types of astrocytic tumours , but not between anaplastic astrocytoma and giant cell glioblastoma. DTI is essential to preoperative evalution of astrocytic tumours.

Based on Huangdi' s Internal Classic and a great deal of clinical verification, in combination with new discoveries of the nerve, the meridian electromagnetic field and the quantum physics for role of thought outside body, it is proved that the main mechanism of the reinforcing-reducing method in Huangdi's Internal Classic is to promote flow of qi with the doctor's thought, with the needle very few twisted and rotated; discover new mechanisms of the reinforcing-reducing method, newly explain and clinically verify many basic standpoints about the reinforcing-reducing, and name as "acupuncture therapy of promoting qi with thought". The method has a strong reinforcing-reducing function and do not need the needle feeling, and is directly related with doctor's idea. It is emphasized specially that it can be carefully adopted only when full syndrome differentiation is made and strictly obey the contraindications in Huangdi's Internal Classic, otherwise it has very serious danger. This kind of model that doctor's mental effect is translated into the patient's biological effect put forward new problem, new thinking for brain sciences and modern acupuncture studies.

OBJECTIVETo explore the relatively efficacious acupuncture treatment for intractable systremma.

METHODSOne hundred and fifty cases were randomly divided into an observation group (n = 100) and a control group (n = 50). Both groups were received the warming needling treatment combined with cupping. The needle was inserted on to sciatic nerve at Huantiao (GB 30) in the observation group, but in the control group, the needle was not needled on sciatic nerve. The effectiveness of the warming needling treatment combined with cupping was compared between the two groups.

RESULTSThe effective rate of 98.0% in the observation group was better than that of 86.0% in the control group with a significant difference (P < 0.05).

CONCLUSIONThe warming needling treatment combined with cupping at Huanriso (GB 30) is a better method for intractable systremma, in which the treatment of needle inserted on to sciatic nerve is more effective.

OBJECTIVETo compare the therapeutic effect of warming needle at spinal nerves in front of transverse posterior tubercle of cervical vertebra and acupoints of cervical Jiaji (EX-B 2) on cervical spondylosis of nerve root type.

METHODSOne hundred and eighty cases were randomly divided into an observation group (120 cases) and a control group (60 cases). Both groups were treated with warming needle and cupping therapy. In the observation group, the transverse posterior tubercles of C2-C7 were selected as the safe points for inserting the needle towards the spinal nerves and warming the needle. In the control group, the corresponding acupoints of cervical Jiaji (EX-B 2) were deeply punctured. The rest treatment was same in the both groups.

RESULTSIn the observation group and the control group, the effective rate was 96.7% (116/120) and 78.3% (47/60) respectively, while the clinical curative rate was 74.2% (89/120) and 46.7% (28/60) respectively. There were significant differences between the two groups (both P < 0.01).

CONCLUSIONWarming needle at spinal nerves in front of transverse posterior tubercle of cervical vertebra, as a main therapy for treating cervical spondylosis of nerve root type, is a safe and effective method that is better than acupuncture at the acupoints of cervical Jiaii (EX-B 2).

OBJECTIVETo compare the efficacy difference on the treatment of supraspinal ligament injury in deficiency syndrome between only-puncturing at Dazhong (KI 4) and routine acupuncture therapy and then explore an optimum process.

METHODSOne hundred and twenty-six cases were randomly divided into a Dazhong group (63 cases) and a routine acupuncture group (63 cases). Based on the same treatment including TDP irradiation, cupping at Shenshu (BL 23), Dachangshu (BL 25), Mingmen (GV 4), Yaoyangguan (GV 3) and Ashi points, the patients in the Dazhong group received only-puncturing Dazhong (KI 4) with respiratory reinforcing method once daily or every other day, three times of which made a course of the treatment, with on interval of one day or without between different courses. For the routine acupuncture group, the same reinforcing method was applied at shenshu (BL 23) pointect, and the other requirements such as courses were also the same.

RESULTSThe cured and markedly effective rate was 88.9% (56/63) in the Dazhong group, which was significantly superior to that of 54.0% (34/63) in the routine acupuncture group (P < 0.01). Compared before and after the treatment, the score of Numerical Rating Scale (NRS) and the clinical symptom score of the two groups were significantly decreased (all PF < 0.01). Compared between the two groups, there were significant differences in NRS and clinical symptom score the Dazhong group was better than the routine acupuncture group (both P < 0.01).

CONCLUSIONThe only-puncturing Dazhong (KI 4) method combined with cupping and TDP irradiation are simple and effective for supraspinal ligament injury in deficiency syndrome.
