Pressure injury (PI) not only reduces the quality of life of patients but also is expensive to manage, placing a heavy financial burden on patients and their families, and society. Despite the increasing diversity of methods used to identify early PI, there are still few methods that can truly and accurately predict early PI. The sub-epidermal moisture scanner is the first U.S. Food and Drug Administration-authorized PI management device that can predict the occurrence and development of PI by measuring the level of local tissue bio-capacitance and monitoring the tissue viability. As an emerging diagnostic instrument, the sub-epidermal moisture scanner has already shown great advantages in clinical practice, which can promote the informatization, digitization, and intelligent prevention and management of PI. This paper introduces the pathophysiological mechanism of PI, elucidates the working principle and parameter settings of the sub-epidermal moisture scanner, its clinical application in monitoring tissue viability in early PI, and its limitation, and looks forward to its future development.

Objective:To investigate the comfort of postoperative rectal cancer patients with indwelling anal tube and analyze the influencing factors, so as to provide a basis for the formulation of prevention and improvement measures.Methods:The subjective comfort self-report method of digital score and visual analog score was used to investigate and analyze 64 patients with indwelling anal canal in anorectal surgery.Results:The main discomfort of patients with indwelling anal tube were difficulty in sitting and getting in and out of bed, of which 43 cases (61.9%) reported moderate and severe sitting difficulty, and 30 cases (46.88%) reported moderate and severe difficulty in getting up and down the bed. The exposed length of anal canal was the influencing factor of discomfort ( Fvalues were 22.018, 18.213, P<0.01). Conclusion:Rectal cancer patients with indwelling anal tube have serious difficulties in sitting position and getting in and out of bed. Corresponding measures should be taken according to the influencing factors and effective intervention methods should be used to improve the comfort of the patients.

Objective: To observe the root and root canal morphology of mandibular second molars in Western Guangxi by CBCT, to provide a reference for clinical diagnosis and treatment. Methods: In total, 564 patients′ 1 128 mandibular second molars that satisfy the inclusion criteria were analyzed with a planmecaromexis CBCT machine and its own image analysis software. The patients′ gender, age and ethnic differences in the root and canal morphology and the symmetry of the bilateral root and canal were statistically analyzed. Results: Among the 1 128 mandibular second molars, 662 were the Zhuang ethnic group and 384 were the Han ethnic group, and 82 were other ethnic groups; the double root type and C-shaped root type accounted for a relatively high proportion: 73.94% and 24.47%, respectively. The detection rates of the double root type were higher in males than in females (P < 0.05); the detection rates of the C-shaped root type were higher in females than in males (P <0.05); the root type of the teeth was mainly double-rooted in the Zhuang ethnic group (P<0.01). The incidence of type IV in the mesial root of the double root type mandibular second molar was the highest (P < 0.01), and the incidence of type I in the distal root was the highest (P < 0.01). The C-shaped root canal is more continuous at the mouth of the root canal, more downward corresponds to a worse continuity: in three different levels of root canal orifice, root middle and root apex, the root canal orifice is dominated by the C1 type, and both root middle and root apex are mainly C3-type (P < 0.01). The difference in symmetry of bilateral roots and root canals was statistically significant among different gender groups, age groups, and ethnic groups (P < 0.05): there were more males than females, the results in the 18-35-year-old group and the Zhuang ethnic group were higher. Conclusion The root and root canal morphology of mandibular second molars in western Guangxi people are complex and changeable. The roots are mainly double root type in the Han ethnic group and the Zhuang ethnic group. C-shaped roots are also common. The detection rate of C-shaped roots in the Zhuang ethnic group was higher, and the symmetry rate of bilateral roots and that of bilateral root canals was higher in the Zhuang ethnic group than in the Han ethnic group.

Objective:To compare the effects of non-woven cotton of surgical dressing and medical gauze in surgical cavity wounds.Methods:A total of 118 patients with surgical cavity wounds in Run Run Shaw Hospital Affiliated to Medical College of Zhejiang University from March to August in 2017 were recruited and divided into two groups by random digits table method, 58 in the observation group and 60 in the control group. The wounds were filled with non-woven cotton of surgical dressing in the observation group and medical gauze was received in the control group. The wound healing, drainage, surrounding skin maceration, the amount of fluid absorption, the pieces of dressings used, residues of yarn, the time of dressing change and the costs of treatment were compared between the two groups.Results:There was no significant difference in the healing rate, surrounding skin macerations and the cost between the two groups ( P>0.05). The intervention group was superior to the control group in the following indicators: the none-residual rate of yarn in the wound were 100.0% (282/282), the median amount of liquid absorbed were 5.43 g, the median pieces of dressings used were 14.00 pieces, the median time of dressing change were 98.00 s, while those index were 70.7% (208/294), 4.29 g, 19.50 pieces, 152.00 s in the control group, compared to the control group, the observation group showed a higher none-residual rate of yarn, more liquid absorbed, less dressing used, less dressing change time in the observation group, the difference was statistically significant ( χ2 value was 96.968, Z values were 2.199, 2.364, 3.852, P<0.05 or 0.01). Conclusions:The non-woven cotton of surgical dressing has no residual yarn in the wound, more liquid absorption, less pieces of gauze, and shorten dressing change time than the medical gauze. It can be used as a kind of superior surgical drainage gauze.

Heat stroke is the most serious type of heat-related diseases, and the induced multiple organ dysfunction syndrome (MODS) is an important cause of death for heat stroke patients. The cardiovascular system is one of the important targets of heat injury. Studies have reported that heat stress can lead to myocardial inhibition, abnormal heart conduction and blood flow redistribution, thus changing the hemodynamic state, leading to obvious abnormalities in electrocardiogram, echocardiography, myocardial injury biological markers and hemodynamic indicators of patients with heat stroke. In this article, the pathophysiological and histological changes and clinical manifestations of heatstroke-induced myocardial injury are reviewed, aiming to provide references for further understanding and research of myocardial damage caused by hyperthermia.

Objective To explore the changes in gravida's age and its influences on maternal and neonatal complications under China's two-child policy.Methods This study retrospectively analyzed the clinical data such as adverse gestational complications and fetal condition of 42 771 gravidas delivering at Changzhou Maternity and Child Health Care Hospital Affiliated to Nanjing Medical University from July 2013 to December 2017.According to their age at delivery,they were divided into three groups:the younger maternal age group (1 140 cases,＜20 years),the advanced maternal age group (4 307 cases,≥ 35 years) and the median maternal age group (37 324 cases,≥ 20 and ＜35 years).Chi-square test was used to compare the differences among groups.Cochran-Armitage test was used for trend analysis.The risks of various complications in younger and advanced maternal age groups were analyzed by binary logistic regression analysis.Results (1) The proportion of advanced maternal age pregnancies tended to rise gradually year by year (Z=-9.909,P＜0.001).However,the figure of younger gravidas remained low and presented a downward trend (Z=10.685,P＜0.001).(2) The incidence of pregnant complications in the younger,advanced and the median maternal age groups were 52.8％ (602/1 140),72.3％ (3 116/4 307) and 56.5％ (21 091/37 324),respectively.Compared with the median maternal age group,the advanced maternal age group was at greater risks of premature delivery [9.0％ (3 343/37 324) vs 11.6％ (499/4 307),x2=124.233,P＜0.001],fetal growth restriction (FGR) [0.6％ (218/37 324) vs 1.2％ (50/4 307),x2=20.087,P＜0.001],postpartum hemorrhage [5.7％ (2 120/37 324) vs 7.8％ (336/4 307),x2=31.299,P＜0.05],hypertensive disorders in pregnancy(HDP) [4.2％ (1 561/37 324) vs 8.7％ (376/4 307),x2=180.013,P＜0.001],gestational diabetes mellitus (GDM) [7.6％ (2 845/37 324) vs 15.1％ (650/4 307),x2=280.126,P＜0.001]and placenta previa [1.7％ (621/37 324) vs 3.8％ (165/4 307),x2=97.904,P＜0.001],and the younger maternal age group was at greater risks of HDP [4.2％ (1 561/37 324) vs 5.9％ (67/1 140),x2=4.234,P=0.040],fetal distress [3.5％ (1 325/37 324) vs 5.1％ (58/1 140),x2=7.546,P=0.006],premature delivery [9.0％ (3 343/37 324) vs 15.0％ (171/1 140),22=48.668,P＜0.001] and FGR [0.6％ (218/37 324) vs 1.1％ (12/1 140),x2=4.086,P=0.043].(3) Gestational complications in the younger maternal age group were mainly related to the fetuses such as premature rupture of membranes (PROM) and premature delivery,while the advanced maternal age group had a higher incidence of maternal complications,especially GDM and HDP.(4) Most of the gravidas of advanced maternal age with HDP developed severe preeclampsia (47.9％,180/376),while mild preeclampsia was dominant in the median maternal aged HDP women (45.4％,708/1 561).(5) The advanced maternal age group had higher risk of stillbirth,premature delivery,FGR,placenta previa,GDM,HDP and postpartum hemorrhage [OR(95％CI):1.91 (1.29-2.84),1.33 (1.21-1.46),1.66 (1.21-2.28),2.56 (2.15-3.04),2.39 (2.19-2.61),2.36 (2.11-2.65),1.46 (1.31-1.62);all P＜0.05],but lower risks of fetal distress and PROM [OR(95％CI):0.79 (0.65-0.95) and 0.88 (0.81-0.96);both P＜0.05].The younger maternal age group had a higher risk of premature delivery [OR(95％CI):1.97 (1.61-2.40);P＜0.001],but significant lower risks of PROM and GDM [OR(95％CI):0.77 (0.62-0.95) and 0.05 (0.02-0.16);both P＜0.05].Conclusions Maternal age is closely related to the adverse outcomes of pregnancy.Two-child policy in China will bring about changes in maternal age and composition of pregnant complications.
