Bushen Huoxue Fang improves recurrent miscarriage in mice by down-regulating the JAK2/STAT3 pathway / 南方医科大学学报

OBJECTIVE@#To investigate the efficacy of Bushen Huoxue Fang (BSHXF, a traditional Chinese medicine formula) for improving recurrent spontaneous abortion (RSA) in mice and the role of tyrosine kinase (JAK2) and transcriptional activator (STAT3) signaling pathway in its therapeutic mechanism.@*METHODS@#Female CBA/J mice were caged with male DBA/2 mice to establish RSA mouse models, which were randomly divided into model group, dydrogesterone group and BSHXF group, with the female mice caged with male BALB/c mice as the control group (n=6). From the first day of pregnancy, the mice were subjected to daily intragastric administration of BSHXF, dydrogesterone, or distilled water (in control and model groups) for 12 days. After the treatments, serum levels of antithrombin III (AT-III), activated protein C (APC), tissue plasminogen activator (t-PA), progesterone, human chorionic gonadotropin (HCG), and estradiol (E2) were detected in each group using ELISA. HE staining was used to observe the morphological changes of the endometrium of the mice. Western blotting was performed to determine the expressions of p-JAK2, p-Stat3 and Bcl-2 in the placenta of the mice.@*RESULTS@#Compared with the control mice, the mouse models of RSA showed a significantly increased embryo loss rate with decreased serum levels of AT-III, T-PA, progesterone, APC and HCG, increased placental expressions of p-JAK2, p-STAT3 and Bax, and decreased expression of Bcl-2 (P < 0.05). Treatments with BSHXF and dydrogesterone both increased serum levels of AT-III, t-PA and HCG in the mouse models; Serum APC level was significantly reduced in BSHXF group and serum progesterone level was significantly increased in dydrogesterone group (P < 0.05).@*CONCLUSION@#BSHXF can improve the prethrombotic state and inhibit cell apoptosis by downregulating the JAK2/STAT3 pathway to increase the pregnancy rate in mouse models of RSA.

Investigation of extrauterine growth restriction in very preterm infants in Chinese neonatal intensive care units / 中华儿科杂志

Objective: To comprehensively assess the current status of extrauterine growth restriction (EUGR) in very preterm infants (VPI) and its associated factors in Chinese neonatal intensive care units (NICU). Methods: In this cohort study, 6 179 preterm infants born at <32 weeks' gestation were included, who were admitted to 57 hospitals in the China Neonatal Network in 2019 and hospitalized for ≥7 days. EUGR was evaluated by a cross-sectional definition (weight at discharge<10th percentile for postmenstrual age), a longitudinal definition (decline in weight Z score>1 from birth to discharge), and weight growth velocity. The comparison between infants with and without EUGR was conducted by t-test, Mann-Whitney U test or χ2 test as appropriate. Multivariable Logistic regression models were used to evaluate associations between EUGR with different definitions and maternal and neonatal factors, clinical practices, and neonatal morbidities. Results: A total of 6 179 VPI were enrolled in the study, with a gestational age of (29.8±1.5) weeks and birth weight of (1 365±304) g; 56.2% (3 474) of them were male. Among them, 48.4% (2 992 VPI) were cross-sectional EUGR and 74.9% (4 628 VPI) were longitudinal EUGR. Z score of weight was (0.13±0.78) at birth and decrease to (-1.35±0.99) at discharge. The weight growth velocity was 10.13 (8.42, 11.66) g/(kg·d). Multivariate Logistic regression analysis showed that among the influential factors that could be intervened after birth, late attainment of full enteral feeds (ORadjust=1.01, 95%CI 1.01-1.02, P<0.001; ORadjust=1.01, 95%CI 1.01-1.02, P<0.001), necrotizing enterocolitis≥Ⅱstage (ORadjust=2.64, 95%CI 1.60-4.35, P<0.001; ORadjust=1.62, 95%CI 1.10-2.40, P<0.001) and patent ductus arteriosus (ORadjust=1.94, 95%CI 1.50-2.51, P<0.001; ORadjust=1.63, 95%CI 1.29-2.06, P<0.001) were all associated with increased risks of both cross-sectional and longitudinal EUGR. In addition, late initiation of enteral feeds (ORadjust=1.06, 95%CI 1.02-1.09, P=0.020) and respiratory distress syndrome (ORadjust=1.45, 95%CI 1.24-1.69, P<0.001) were all associated with cross-sectional EUGR. Breast milk feeding (ORadjust=1.33, 95%CI 1.05-1.68, P<0.001) was associated with a higher risk of longitudinal EUGR. Conclusions: The incidence of EUGR in VPI in China is high. Some modifiable risk factors provide priorities to improve postnatal growth for VPI. Nutritional management of VPI and the efforts to decrease the incidence of complications are still the focus of clinical management in China.

Advance in Muscle Ultrasound Assessment for Intensive Care Unit Patients (review) / 中国康复理论与实践

Limitation of consciousness level in intensive care unit (ICU) patients poses a great challenge to muscle strength assessment. Muscle ultrasound does not require patient cooperation, and can objectively measure significant changes in muscle cross-sectional area, thickness, echo intensity, and pennation angle to identify muscle atrophy early in the ICU. At the same time, muscle ultrasound technology is easy to be grasped by ICU doctors and nurses, and both show great reliability, which has certain significance for identifying patients at high risk of ICU-acquired weakness. In addition, ultrasound quantitative assessment of muscle has great value for predicting patient outcomes. Large-scale studies on the diagnostic value of ultrasound in ICU-acquired weakness are still lacking, and standardized ultrasound assessment scheme requires further discussion.

Correlation between referred pain distribution and acupoint sensitization in patients with intestinal diseases / 中国针灸

OBJECTIVE@#To observe the correlation between referred pain distribution and acupoint sensitization in patients with intestinal diseases.@*METHODS@#In clinical research, 443 patients from 8 hospitals were recruited, including the outpatients and inpatients of Crohn's disease (=143), ulcerative colitis (=108), chronic appendicitis (=87) and other intestinal diseases (=105). The site with tenderness on the body surface and the morphological changes of local skin were observed and recorded in the patients. Using a sensory tenderness instrument, the pain threshold at the sensitization point was measured in 60 patients with ulcerative colitis. In animal experiment, SD rats were used and divided into a enteritis group (=8), in which the enteritis model were established, and a control group (=3), in which no any intervention was given. After the injection of Evans blue (EB) at caudal vein, the blue exudation points on the body surface were observed and the distribution rule was analyzed statistically.@*RESULTS@#The referred pain on the body surface in the patients with intestinal diseases was mainly located in the lower abdomen (93.9%, 416/443), the lumbar region (70.9%, 314/443) and the lower legs (33.0%, 146/443). The diameter of tenderness region was 1.5 to 2.5 cm. Compared with the region without sensitization, the pain threshold of the sensitization point in the patients with ulcerative colitis was reduced significantly (<0.001). The referred pain on the body surface in the patients with appendicitis was located in the right lower abdomen (97.7%, 85/87), the waist and back (54.0%, 47/87) and the right lower limbs on the medial side (71.3%, 62/87). The tenderness region was 1 to 2 cm in diameter and was irregular in form. After modeling of enteritis in the rats, the EB exudation points were visible from T to L.@*CONCLUSION@#Intestinal diseases induce referred pain on the body surface where is the same as or adjacent to the location of the spinal segment corresponding to the affected intestinal section. These sensitization regions are related to the locations of acupoints.

(2) There was statistical difference in inter-group comparison of total Fugl-Meyer motor functions scores and FIM scores, or scores for neurological impairment (P < 0.01). The improvement of Fugl-Meyer motor functions grading and neurological impairment grading was obviously superior in the experimental group at month 2 and 5 of follow-ups. The distribution of FIM grading was also better in the experimental group at month 5 of follow-ups (P < 0.05, P < 0. 01).</p><p><b>CONCLUSIONS</b>Both acupuncture combined exercise training and relearning and physical training and relearning could effectively promote the rehabilitation of stroke patients, reduce their neurological impairment degrees, improve motor functions and independent capacities. Better long-term efficacy could be obtained by acupuncture combined exercise training and relearning.</p>

Effects of extensively hydrolyzed protein formula on feeding and growth in preterm infants: a multicenter controlled clinical study / 中国当代儿科杂志

<p><b>OBJECTIVE</b>To study the effects of extensively hydrolyzed protein formula (eHF) on the feeding and growth in preterm infants through a multicenter controlled clinical study.</p><p><b>METHODS</b>Preterm infants admitted to eight upper first-class hospitals in China between February 2012 and December 2013 were randomly selected. They were divided into two observation groups and two control groups. The first observation group consisted of preterm infants with a gestational age of <32 weeks, who were fed with eHF for 10-14 days after birth and then with standard preterm formula (SPF) until discharge. The second observation group consisted of preterm infants with a gestational age of 32-34 weeks, who were fed with SPF after birth, but were switched to eHF (7-14 days) if suffering feeding intolerance at 6-8 days after birth. The two control groups with corresponding gestational ages kept to be fed with SPF after birth. Clinical data were recorded to compare feeding condition, physical growth, blood biochemical indices, and major complications between different groups.</p><p><b>RESULTS</b>A total of 328 preterm infants were enrolled. Preterm infants with a gestational age of <32 weeks in the observation group had a significantly shorter meconium evacuation time than in the corresponding control group (P<0.05). They also had significantly lower levels of serum total bilirubin at weeks 1 and 2 after birth compared with the control group (P<0.05). The observation group needed more time in reaching enteral nutrition (EN) basic energy uptake of 50 kcal/(kg·d), partial parenteral nutrition (PPN), hospitalization, and corrected gestational age at discharge compared with the controlled infants (P<0.05). There was no difference in the incidence of extrauterine growth retardation (EUGR) at discharge between the two groups (P>0.05). Preterm infants with a gestational age of 32-34 weeks in the observation group had significantly lower serum total bilirubin levels at 2 weeks after birth compared with the corresponding control group (P<0.05). They required more time in achieving EN basic energy and PPN than in the control group (P<0.05). There was no difference in the incidence of EUGR at discharge between the two groups (P>0.05).</p><p><b>CONCLUSIONS</b>For preterm infants, eHF can improve gastrointestinal motility, accelerate bilirubin metabolism and excretion and does not increase the incidence of EUGR.</p>
