Objective To study the application of food hand measurement on the diet therapy and evaluate its rationality. Methods According to the method of stratified interception, 415 adults were chosen in Zhoushan City. Their height, weight, fist, hand palm and thumb size were measured. The cooked food volume measurement method was built by the daily dietary food exchange method of hand position measurement, the measured protein foods using the cube and vegetable or oil with common tableware. The cooked volume measurement method was compared with the weighing method applying to diabetic diet. Results The fist and hand palm volume in shorter people were (228.13-310.85) ml and (62.22-84.78) ml, those in the taller people were (250.00-388.95) ml, (68.18-106.08) ml, and those in taller people were (345.00-432.35) ml and (94.09-117.91) ml. In the same height group, when the one's weight was greater, the fist and hand palm volume were larger. When the weight was the same but the height was taller, the fist and hand palm volume were larger. The vegetable oil hand measurement was not appropriate by the measurement of hand position volume. The calories error of proteins and the staple food with hand measurements was larger than weighing method in the tall and obese people, that was not enough in the slim and short people. And the cooked volume measurement method that combined hand measurements with the cube and common tableware was appropriate to diabetic diet. Conclusion The hand measurement method combined with cube and common tableware box was suitable for diet therapy for diabetes. This method could be helpful to increase treatment compliance to balanced diet.

Objective To investigate the feasibility of transient blocking of both pulmonary artery and veins for surgical treat- ment of central lung cancer with stage Ⅲ to preserve the normal pulmonary.Methods Firstly,the relation of the pulmonary artery, the lung neoplasm and the enlarged mediastinal lymph nodes was investigated.If the hilum of lung remained frozen,the pericardium was opened and the pulmonary artery,the upper and lower lobe pulmonary veins were dissected.Then those three vessels were blocked.When the pulmonary cireulation was stopped,bloodless lobectomy and pulmonary artery angioplasty and/or anastomosis were performed.Then the blockers were released,and pulmonary circulation was restored.The time of blocking was(35?15)minutes (16～66 minutes).Results All 20 patients suffer from stage Ⅲ central lung cancer,which' s the hila of lung remained frozen,re- ceived complete resection of the tumor.The normal functioning pulmonary tissue in the 20 patients was preserved instead of pneumone- ctomy.The average amount of bleeding was 256 ml(180～420 ml)during operation.All 20 patients recovered well.Conclusion Transient blocking of both pttlmonary artery and veins for surgical treatment of stage Ⅲ central lung cancer is and innovation in surgical technique,which makes the operation safe and easy.This technique may provide a chance to patients,with poor cardio-pulmonary function.In addition,this technique widens the surgical indications for patients suffering from lung cancer.

Objective To study the effect of different types of renal puncture needles on the risk of bleeding after renal puncture.Methods A retrospective analysis was performed on 428 patients who under-went renal biopsy in the Third Affiliated Hospital of Chongqing Medical University and Jiulongpo District People's Hospital of Chongqing from January 2020 to December 2022.Different types of puncture needles were used to compare the occurrence of postoperative bleeding complications(hematoma,hematuria).Results The incidence of bleeding complications after renal puncture in 428 patients was 21.0％(90/428),of which the incidence of hematoma was 18.9％(81/428),the incidence of hematuria was 2.1％(9/428),the median decrease in hemoglobin(Hb)was 5 g/L,and the incidence of serious complications such as blood transfusion and interventional therapy was 0.7％(4/428).The patients with different types of renal puncture needles were grouped(16G group,18G group).There was no significant difference in baseline data and distri-bution of renal pathological types between the two groups(P＞0.05).The incidence of postoperative bleeding in 16G group and 18G group was 22.4％(52/232)and 19.4％(38/196),respectively.The incidence of hema-toma was 20.6％(48/232)and 16.8％(33/196),respectively.The incidence of hematuria was 1.7％(4/232)and 2.6％(5/196),respectively.The decrease of Hb was 6(0,16)g/L and 4(0,17)g/L,respectively.There was no significant difference(P＞0.05).There was no significant difference in the incidence of serious compli-cations such as blood transfusion,interventional therapy and Hb decrease＞10 g/L between the two groups(P＞0.05).Conclusion Ultrasound-guided renal biopsy is safe and has a low incidence of serious complica-tions.There was no significant relationship between different puncture needle types and postoperative bleeding risk.
