Bedridden patients mostly use the back cushion object,raise the bedside position,and other methods to obtain the semi-decumbent position.However,the existing methods have shortcomings such as insufficient execution,wrong angle estimation,weak consciousness,forgetting,decreased comfort,easy to cause pressure sore and aspiration pneumonia.To solve the shortcomings of the existing eating position placement method,the department of geriatric medicine team of Tongxiang City Hospital of Traditional Chinese Medicine designed a bed-rest pillow for bed patients to eat or other requirements of semi-lying position,and obtained the National Utility Model Patent of China(patent number:ZL 202122859891.4).This device places the pillow on a flat bed,with the back of the pillow next to the head of the bed for support and to prevent sliding.The patient was placed in a retainer slot,head in the first retainer slot,shoulder and back in the second retainer slot,waist and abdomen in the third retainer slot,and hands on the armrests on both sides of the pillow.The use of pillows for bedridden patients is simple and easy to learn,convenient,economical and practical,time-saving and labor-saving,and convenient supervision and inspection,which can reduce complications such as aspiration and pressure ulcers,thereby reducing the economic burden of the patient,improving the quality of life,and improving the satisfaction of patients and their families,and is worthy of clinical promotion and use.

Objective:To investigate the occurrence of inadequate specimens of thyroid nodule fine needle non-aspiration cytology and its possible influencing factors.Methods:Clinical data of 1571 patients with FNAC of 1638 thyroid nodules were analyzed retrospectively, according to whether the FNAC specimen were adequate or not, all cases were divided into adequate group and inadequate group. The related influencing factors on inadequate specimen were analyzed by univariate analysis and multivariate logistic regression.Results:Inadequate specimens occurred in 301 of 1638 (18.4%) nodules. Logistic regression analysis showed that the influencing factors of overall specimen adequacy included operator experience ( P=0.00) , nodules size≤0.5 cm ( P=0.00) , eggshell calcification ( P=0.00) , and cystic ( P=0.00) . Excluding the impact of operator experience, the influencing factors of specimen adequacy included nodules size≤0.5 cm ( P=0.00) , eggshell calcification ( P=0.00) , and cystic ( P=0.00) . Conclusions:Operator experience, nodules size≤0.5 cm, cystic, together with eggshell calcification are influencing factors of specimen adequacy of fine needle non-aspiration cytology in thyroid nodules. For experienced operators, what restrict specimen adequacy is the limitation of FNAC technique. For inexperienced operators, what restrict specimen adequacy is operator’s experience.

Objective:To observe the clinical effect of treatment with follicular unit extraction (FUE) and transplantation in treating cicatricial alopecia.Methods:The retrospective cohort study was conducted. From January 2012 to January 2018, 56 patients (36 males and 20 females, aged (25±9) years, 1% to 30% alopecia area of the whole scalp area) who met the inclusion criteria visited the outpatient department of the First Affiliated Hospital of Xi'an Medical University. They were treated with FUE transplantation. The procedure of treatment was performed through the preoperative planning, follicular extraction, follicular preparation, punching recipient site and hair transplantation. The survival rate of hair and density of survived hair were calculated, hair growth and complication were observed. The evaluation was conducted through questionnaire survey by 4 levels: very satisfied, satisfied, not satisfied, and not at all satisfied with effects.Results:After a follow-up of 9 to 24 months, the survival rate of hair in 56 patients was (70±9)%, and the density of survived hair was (35±8) roots/cm 2. In the evaluation of the curative effect after the first stage surgery, 34 cases (60.7%) were very satisfied, 16 cases (28.6%) were satisfied, and 6 cases (10.7%)thought the treatment was effective but not satisfied. Six unsatisfactory patients and 16 satisfactory patients underwent the second-stage transplantation, with 19 (86.4%) of them being very satisfied and 3 cases (13.6%) satisfied after the second-stage operation. None of the patients underwent the third-stage surgery. The transplanted hairs grew naturally, and there were no serious complications in all cases. Conclusions:FUE transplantation can effectively treat and improve cicatricial alopecia with less trauma, fewer complication, no scar in the donor site and rapid post-operative recovery, so it is worthy of clinical promotion.

Objective To evaluate the clinical efficacy and safety of simultaneous integrated boost intensity-modulated radiotherapy (SIB-IMRT) to the tumor center in the treatment of bulky cervical cancer with massive bleeding in the first course radiotherapy.Methods Twenty-one cases with bulky cervical cancer complicated with massive vaginal bleeding were enrolled.At the first three times of external irradiation,a high dose radiotherapy (15 Gy/3 fractions) was delivered to the tumor center (the region retracted 2 cm from the periphery of cervical mass),followed by conventional irradiation (2 Gy/fraction) in the posterior course.Conventional dose irradiation (46 Gy/23 fractions) was given to the tumor periphery and pelvic lymphatic drainage area throughout the whole course.Concurrent chemotherapy by cisplatin at a dose of 25 mg/m2 was delivered weekly.After the external irradiation,intracavitary radiotherapy was given (20 Gy/4 fractions).Results Within 24 h after the first course radiotherapy,the volume of vaginal bleeding was significantly decreased by 50％ and the bleeding was almost stopped within one week.The hemostasis rate was 100％.Conclusions SIB-IMRT into the center of bulky cervical cancer is an efficacious treatment of massive vaginal bleeding.

Objective To establish and verify the fluctuation of reference intervals for biochestry parameters in routine physical exami-nation. Methods The results of biochemistry parameters,i.e., total protein (TP), albumin (Alb), total bilirubin (T-Bil), alanine aminotransferase (ALT), glucose (Glu), urea (Urea), creatinine (Cr), uric acid (UA), triacylglycerol (TG) and total cholesterol ( TC) from 2 089 healthy subjects in routine physical examination during consecutive 2014, 2015 and 2016 were randomly collected, in which all the results were within the reference range. The ratio (λ1) of the results of 2015 to those of 2014, and ratio (λ2) of the re-sults of 2016 to those of 2015 were calculated. λ1was analyzed statistically to establish the fluctuation of reference interval (CIλ). CIλ was verified by λ2.The personalized reference interval (CIp) was established by multiplying each result of 2015 and the upper and low-er limits of CIλ. The CIpwas verified by the results of 2016. The ratios of CIpto the upper and lower limits of conventional reference in-terval were calculated. Results The values of CIλwere as follows: TP: 0.91 to 1.08, Alb: 0.91 to 1.08, T-Bil: 0.58 to 1.74, ALT:0.49 to 1.99, Glu: 0.84 to 1.20, Urea: 0.67 to 1.50, Cr: 0.82 to 1.22, UA: 0.77 to 1.32, TG: 0.51 to 1.98 and TC: 0.80 to 1.26. Compared with conventional reference interval, the ratio of the upper and lower limits of CIp was lessened. Conclusion The personal-ized reference interval (CIp) which may increase the sensitivity of conventional reference intervals was established and verified.

Objective To summarize the operational experience and explore the best surgery strategy in cicatricial alopecia.Methods Clinical date of 80 cases of cicatricial alopecia during January 2012 to December 2016 were analyzed retrospectively.The operation methods and related adverse events were recorded.Patients were followed-up on the postoperative 1 week,1 month,3 months,6 months and 1-2 years.The outcomes were evaluated by a 4-levels questionnaire:very satisfied,satisfied,not satisfied,and no effect.Results Forty cases were operated with expanded skin flap + Follicular unit extraction (FUE) transplantation,10 cases with scar resection + FUE repair,and 30 cases only with FUE.Twenty cases were completed treatment with single-stage surgical operation,and 60 cases with two-stage surgical operation.A percentage (70％) of patients was very satisfied and 30％ were satisfied after one-stage surgical operation.A percentage (85％) of patients was very satisfied and 15％ were satisfied after two-stage surgical operation.Conclusions The cicatricial alopecia needs comprehensive surgical treatment.FUE is a best additional operation technology.The effect of combined treatment is better than single therapy method in large area cicatricial alopecia.

Objective:To study the relationship between IL-1β and TNFα expression and cell apoptosis in gingival tissue of the subjects with diabetes associated periodontitis(DAP).Methods:20 cases of DAP(group DAP) and 20 cases of health controls(group H)were included.The cell apoptosis and the ultrastructural changes in gingival tissue were observed by Tunnel staining and transmission electron microscope (TEM).IL-1β and TNFα expression in gingival tissue were detected by immunohistochemical staining.SBI,GI,PD and AL of the subjects were measured.The relationship between the level of IL-1β,TNFα and the cell appotosis was analyzed.Results:Apoptosis was obvious in prickle cells and basal cells of gingival tissue of DAP group.The percentage of apoptosis cells of DAP group was significantly higher than that of group H(P＜0.01).The expression of IL-1β and TNFα in group DAP was significant higher than that of group H (P＜0.01),and the mainly positive expression cells were macrophages,plasmocytes and lymphocytes.Conclusion:IL-1β and TNFα play a role in cell apoptosis in the gingival tissue of the patients with DAP.

Objective To establish and verify the personalized reference interval of blood cells.Methods The results of blood cells from 2 089 health subjects in 2014,2015 and 2016 were collected.The ratio of the later results to the previous results was defined as the fluctuation (λ).The ratio (λ1) of the results of 2015 to the results of 2014 was calculated and λ1 was analyzed statistically to establish the fluctuation reference interval (CIλ).The ratio (λ2) of the results of 2016 to the results of 2015 was calculated.λ2 was used to verify λ2.The personalized reference interval (CIp) was established by multiplying each result of 2015 and CIλ.CIp was verified by results of 2016.The ratio of the upper and lower limits of CIp was calculated.The ratio of the upper and lower limits of the reference interval (WS/T 405) was calculated.Results The values of CIλ were as follows:WBC (0.66 to 1.53),L(0.67 to 1.51),M (0.50 to 2.00),N(0.56 to 1.78),E(0.4 to 2.51),PLT(0.76 to 1.32),RBC(0.92 to 1.12),Hb(0.92 to 1.11),Hct(0.91 to 1.12),MCV(0.95 to 1.07),MCH(0.95 to 1.05)and MCHC(0.94 to 1.06).The validation tests of CIλ and CIp showed that both CIλ and CIp were suitable for this laboratory.Compared with the reference interval of professional criteria,the ratio of the upper and lower limits of the CIp was smaller than that of traditional criteria.Conclusion CIp for this laboratory was established and verified.Compared with traditional criteria,CIp should be more personalized and highly sensitive.
