Objective To investigate the reference interval of platelet‐related parameters including mean platelet volume (MPV) ,platelet distribution width (PDW) ,platelet hematocrit (PCT) .Methods Used Sysmex XN‐9000 assembly line and PEN‐TRA 120 hematology analyzer to analysis the venous blood cells for 3 415 cases of 16 to 90 years old physical examination personnel in Mianyang Central Hospital ,the platelet‐related parameters results of 2 718 standard healthy population by screening were statis‐tically analyzed .Results Platelet‐related parameters 95% reference interval (2 .5% -97 .5% ) of XN assembly line :M PV 9 .9-14 . 7 fL ,PDW 11 .2% -24 .3% ,PCT 0 .15% -0 .30% ;Platelet‐related parameters of 95% reference interval of PENTRA 120:MPV 8 .4-12 .7 fL ,PDW 13 .8% -24 .8% ,PCT 0 .12% -0 .26% ;comparison between the instruments :MPV ,PDW ,PCT results showed significant differences (P<0 .05);comparison between men and women :PCT test results of XN assembly line were differ‐ent (P<0 .05) ,MPV ,PDW ,PCT results of PENTRA 120 were different (P<0 .05);comparison between age groups :PCT result of all ages between men and women were different in XN assembly line (P<0 .05) ,in PENTRA 120 ,MPV ,PDW ,PCT results be‐tween ages were different in men (P<0 .05) ,PCT results between ages were different in women (P<0 .05) .Conclusion Each la‐boratory should establish the laboratory supporting biological reference interval of platelet‐related parameters based on different in‐struments ;in practical applications ,should set the reference interval for different gender or age .

Objective:To observe the effect of Jieyu Anmian prescription of Chinese medicine foot bath on gastrointestinal function in patients with digestive system tumor during perioperative period.Methods:A total of 130 patients with digestive system tumors were chosen from January 2019 to March 2020 for the first time visits to the first hospital of lanzhou university for surgical treatment, 15 cases lost follow-up, and the rest 115 cases of patients were divided into the experimental group (59 cases) and the control group (56 cases) according to random number table method. The control group using conventional care method, the experimental group was treated with Jieyu Anmian washing formula on the basis of routine nursing care for 10 days. During the foot bath, the recovery of gastrointestinal function, the time of the first exhaust and defecation, the length of stay, the cost of stay and the satisfaction of patients were compared between the two groups.Results:The recovery time of bowel sounds, anal exhaust time and first defecation time of the experimental group were all earlier than those of the control group (16.21±11.81) h, (19.64±12.40) h and (41.98 ±19.16) h, respectively, while those of the control group were (27.34±31.47) h, (35.81±18.26) h and (34.47±16.41) h, respectively. The differences were statistically significant ( t value was -2.41, -5.33, 2.17, P< 0.05). The results of the survey of patient satisfaction showed that the experimental group was superior to the control group, with 97.47 ± 4.37 in the experimental group and 94.19 ± 3.29 in the control group, with statistically significant differences ( t value was 3.89, P<0.01). The satisfaction of doctors in the experimental group was 97.41 ± 6.25 and 94.21±5.91 in the control group, with statistically significant difference ( t value was 3.95, P<0.05). The satisfaction of nurses in the experimental group was 97.58 ± 4.53 and 93.85±5.23 in the control group, and the difference was statistically significant ( t value was 4.12, P<0.05). There was no significant difference between the two groups in terms of length of stay and hospitalization expenses ( P>0.05). Conclusions:Jieyuanmian prescription of Chinese medicine foot bath can promote the recovery of gastrointestinal function, promote the exhaust and defecation, and improve the satisfaction of patients and nurses.

Objective: To compare the clinical effect of a new type of nasal feeding device and the commonly used nasal feeding device at present. Methods: From January 2017 to December 2017, 162 cases of acute severe pancreatitis in the General surgery department two in First Hospital of Lanzhou University were treated with enteral nutrition. According to the random number table method, it was divided into experimental group (82 cases) and control group (80 cases). The experimental group used a new nasal feeding device to implement nasogastric nutrition, while the control group used traditional clinical common devices. The evaluation indexes were as follows: comparison of nasal feeding, comfort (abdominal distention), incidence of diarrhea, effect of nasal feeding and convenience of patients' family members. Results: The number of the evaluation of medical staff was not good, general, good and very good were 3, 3, 27 and 49 cases in the experimental group and 4, 48, 15 and 13 cases in the control group, respectively. There was significant difference between the two groups (Z=-7.14, P=0.00). The number of the evaluation of the patients and their families was not good, general, good and very good were 0, 1, 33 and 48 cases in the experimental group and 34, 31, 11 and 4 cases in the control group, respectively. There were significant differences between the two groups (Z=-7.44, P=0.00). The number of severe abdominal distension, general abdominal distension and no abdominal distension were 22, 42 and 18 cases in the experimental group, 43, 34 and 3 cases in the control group, respectively. There were significant differences between the two groups (Z=-4.14, P=0.00). The number of severe diarrhea, general diarrhea and no diarrhea were 8, 50 and 24 cases in the experimental group, 43, 34 and 3 cases in the control group, respectively. There were significant differences between the two groups (Z=-6.55, P=0.00). The number of inconvenience, general and convenience were 2, 5 and 75 cases in the experimental group, and 18, 43 and 19 cases in the control group, respectively. There was significant difference between the two groups (Z=-8.45, P=0.00). Conclusions The new type of nasal feeding device has good performance and safety. The doctor, nurse and patient have good satisfaction, high evaluation, good convenience and suitable for clinical use.
