OBJECTIVE: To evaluate the effects of acupuncture at Hegu (LI4), Taichong (LR3) and Sanyinjiao (SP6) on pain, anxiety, intrapartum blood loss, labor stage, and neonatal outcomes in primiparas. METHODS: One hundred primiparas were randomly divided into an acupuncture group (50 cases, 1 case was eliminated) and a control group (50 cases). The conventional obstetrical nursing was given in the control group. On the basis of the intervention in the control group, acupuncture was applied at bilateral Hegu (LI4), Taichong (LR3) and Sanyinjiao (SP6) in the acupuncture group. The delivery mode and labor stage, the scores of visual analogue scale (VAS) for uterine contraction pain and Hamilton anxiety scale (HAMA) before and after acupuncture, the intrapartum/postpartum blood loss and massive hemorrhage, as well as the neonatal Apgar score after 1, 5, and 10 min of birth, were compared in the two groups. RESULTS: The cesarean section rate was 4.1% (2/49) in the acupuncture group, which was superior to 10.0% (5/50) in the control group (P<0.05). In the acupuncture group, the time of latent phase of 2-cm cervical dilation, active phase, first and second stages of labor, and total labor stage was shorter than that in the control group (P<0.001), the intrapartum blood loss and massive hemorrhage rate were lower than those in the control group (P<0.001, P<0.05). After acupuncture, the VAS and HAMA scores were decreased compared with those before acupuncture in the acupuncture group (P<0.001), the VAS and HAMA scores were increased compared with those before acupuncture in the control group (P<0.001). In the acupuncture group, the VAS and HAMA scores after acupuncture were lower than those in the control group (P<0.001), the changes of the VAS and HAMA scores before and after acupuncture were larger than those in the control group (P<0.001). There were no statistical differences in neonatal Apgar scores between the two groups (P>0.05). CONCLUSION Acupuncture at Hegu (LI4), Taichong (LR3) and Sanyinjiao (SP6) can effectively alleviate the pain and anxiety, shorten the labor stage, reduce the intrapartum blood loss and incidence rate of massive hemorrhage, and promote spontaneous delivery, thereby enhancing maternal comfort and safety in primiparas.

Objective To investigate the ameliorative effect of Lentinan (LNT) on sodium arsenite (SA)-induced hepatic lipid deposition in mice. Methods C57BL/6 mice were used as the experimental subjects, which were divided into control group, SA-exposed group, LNT + SA-exposed group and LNT control group. Blood and liver tissue samples were collected at the end of the experiment, and serum glutathione transaminase (ALT) and glutathione aminotransferase (AST) levels were detected by enzyme-linked immunosorbent assay (ELISA). A part of liver tissues was stained with hematoxylin-eosin (HE) or oil red O to observe the characteristics of liver pathological damage and lipid deposition, and another part of liver tissues was used to detect triglyceride (TG) and Adiponectin (APN) levels by ELISA. Results Compared with control group or LNT control group, SA-exposed group showed the increased levels of AST and ALT, showing the characteristics of liver histopathological damage and lipid deposition, and the APN level decreased while the TG level increased (P<0.05). Compared with SA-exposed group, the levels of AST and ALT decreased in LNT + SA-exposed group, showing the reduced degree of liver tissue damage and lipid deposition, and APN level upregulated while TG level downregulated (P<0.05). Conclusion Chronic SA exposure induces liver function damage, APN downregulation and lipid deposition in C57BL/6 mice, while LNT intervention leads to the significantly improvement of hepatic damage and lipid deposition, which may be related to the elevated APN level in liver.

OBJECTIVE To explore the changes in chemical compositions and the characteristics of “fried charcoal and saving properties” based on the carbon-frying process of Sophora japonica and its bud. METHODS The slightly， moderately and heavily carbon-fried samples of S. japonica and its bud were prepared. The fingerprints of S. japonica， its bud and carbon-fried samples were established， and common peaks were identified. HPLC method was used to determine the contents of identified components and differential analysis was also performed； the differential components were screened by using chemometric methods， and their content ratios were used to characterize the “fried charcoal and saving properties” of S. japonica and its bud. RESULTS There were 9 common peaks in the fingerprints of S. japonica and its carbon-fried samples， 8 common peaks in those of S. japonica bud and its carbon-fried samples. In the fingerprints of S. japonica and its bud， and their different fried products， 6 components were identified， such as rutin， kaempferol-3-O-rutinoside， isorhamnetin-3-O-rutinoside， quercetin， kaempferol，isorhamnetin. Among them， the contents of rutin， kaempferol-3-O-rutinoside and isorhamnetin-3-O-rutinoside were the highest in slightly carbon-fried samples of S. japonica bud， and the contents of quercetin and isorhamnetin were the highest in moderately carbon-fried samples of S. japonica bud， and the contents of kaempferol were higher in moderately and healily carbon-fried samples of S. japonica bud. The chemometric results showed that the variable importance projection values of rutin and quercetin were both greater than 1. The range of rutin-quercetin content ratio between 9.00-14.00 and 3.00-6.00 respectively could characterize “fried charcoal and saving properties” of S. japonica and its bud. CONCLUSIONS There are significant differences in the chemical compositions of raw and fried products of S. japonica and its bud. Rutin and quercetin may be the differential components that affect their quality， and the ratio range of the two can be used to characterize the “fried charcoal and saving properties” of S. japonica and its bud in the future.

Objective To observe and analyze the influence of the improved ultra-low temperature storage box on the quality of fresh frozen plasma(FFP).Methods A total of 80 qualified whole blood samples(400 mL,O type not includ-ed)collected from July to November in 2023 were selected,and were divided into 4 groups,with 20 samples in each group.Group A:quick-frozen in a traditional low temperature box for 1 hour and then stored in a-30℃cold storage;Group B:quick-frozen in the flat freezer for 1 hour and then stored in a-30℃cold storage;Group C:quick-frozen in a newly im-proved ultra-low temperature storage box for 1 hour and stored in a-30℃cold storage;Group D:quick-frozen in a new im-proved ultra-low temperature storage box for 12 hours and stored in a-30℃cold storage.The contents of FⅧand fibrinogen(Fg)in four groups were detected.Results The contents of FⅧin group B,C and D were significantly higher than those in group A,with statistical difference(P＜0.05),but with no statistical difference among gourp B,C and D(P＞0.05),and no statistical difference in the contents of Fg was found among the four groups(P＞0.05).Conclusion The improved ultra-low temperature storage box is superior to the traditional low temperature box in preparing FFP,and there is no obvious difference between the improved ultra-low temperature storage box and the flat-plate quick freezer.However,the improved ultra-low temperature storage box can make the process of preparing FFP more flexible and improve the efficiency of compo-nent preparation.

Objective This study was performed to explore the use of intramuscular low-dose Zoletil(1.5 mg/kg)combined with isoflurane inhalation for tracheal intubation in miniature pigs while preserving spontaneous respiration by determining the 50％and 95％minimum alveolar concentrations effective inhaled(MAC EI50 and MAC EI95).The goal was to establish a safe anesthetic method for tracheal intubation in miniature pigs in which intubation is difficult.Methods Forty-four Bama miniature pigs underwent general anesthesia.Following sedation with an intramuscular injection of sufentanil,anesthetic induction was performed using mask inhalation of isoflurane with monitoring of the heart rate,blood pressure,respiration,body temperature,oxygen saturation,end-tidal carbon dioxide concentration,and end-tidal isoflurane concentration.The initial end-tidal isoflurane concentration was set at 2.0％.The tracheal intubation conditions and outcomes were evaluated using Cooper's scoring system,and the dose-response relationship was calculated using Dixon's up-and-down method.Probit regression was employed to calculate the MAC EI50 and MAC EI95 along with their 95％confidence intervals(CI).Results In tracheal intubation using direct laryngoscopy with induction by low-dose sufentanil combined with isoflurane inhalation in miniature pigs,the MAC EI50 was 3.10％(95％CI,2.79％～3.56％)and the MAC EI95 was 3.77％(95％CI,3.41％～6.42％).With proper monitoring and airway management planning in place,alveolar isoflurane concentrations ranging from 3.10％to 3.75％were able to maintain stable vital signs in the miniature pigs.Conclusions The use of Zoletil combined with isoflurane inhalation for tracheal intubation in miniature pigs,aimed at preserving spontaneous breathing,is a preferable and safe anesthetic method for oral airway management in miniature pigs with significant potential for widespread application.

Objective To assess the prognostic significance of serum cystatin C(CysC)in combination with bedside renal ultrasound for patients diagnosed with sepsis-induced acute kidney injury(AKI).Methods The study cohort comprised 134 patients with sepsis-induced AKI who were admitted to our hospital between October 2019 and October 2023.Based on the 30 day prognosis,the patients were categorized into a survival group(n=93)and a death group(n=41).Collected clinical data included gender,age,heart rate,underlying diseases,treat-ment modalities,duration of hospital stay,basic biochemical indicators,and Acute Physiology and Chronic Health Evaluation Ⅱ(APACHEⅡ)scores.Renal function markers such as serum creatinine(SCr),blood urea nitrogen(BUN),and cystatin C levels were measured;renal blood flow resistance index(RI)was assessed using bedside routine ultrasound.Cox regression analysis was employed to evaluate factors influencing poor prognosis in patients with sepsis-induced AKI while analyzing the prognostic assessment value of combining cystatin C with bedside renal ultrasound through ROC curves.Results The death group exhibited significantly higher APACHEⅡ scores,SCr,BUN,CysC levels,and RI(all P<0.05)compared to the survival group.Cox regression analysis revealed that both CysC levels and RI were significant prognostic indicators(P<0.05).ROC curve analysis demonstrated that the combined assessment of CysC levels and RI yielded a high diagnostic accuracy of 97.5%in predicting outcomes for patients with sepsis-induced AKI.Conclusion CysC levels and bedside renal ultrasound can serve as prognostic indicators for patients with sepsis-induced acute kidney injury(AKI),thereby guiding clinical treatment.

Objective To evaluate the efficacy and safety of tacrolimus extended-release (Tac-ER) in the early stage after kidney transplantation. Methods Clinical data of 68 recipients undergoing kidney transplantation from 34 pairs of renal allografts were retrospectively analyzed. Two recipients who received bilateral kidneys from the same donor were treated with Tac-ER (Tac-ER group) and tacrolimus immediate-release (Tac-IR) (Tac-IR group) as one of the basic immunosuppressant. The changes of tacrolimus dosage and blood concentration, intra-patient variability (IPV), renal function, incidence of acute rejection, recipient and allograft survival rates and adverse events were statistically compared between two groups. Results The average daily dose of tacrolimus in the Tac-ER group was significantly higher than that in the Tac-IR group (F=8.386, P=0.005). In the Tac-ER group, the mean trough concentration at postoperative 4 d was (6.14±4.04) ng/mL, did not reach the target concentration, significantly lower than (9.41±5.47) ng/mL in the Tac-IR group (F=7.854, P=0.007). In the Tac-ER group, the IPV of trough concentration of tacrolimus within postoperative 1 month was significantly higher than that in the Tac-IR group (0.44±0.15 vs. 0.36±0.12, P=0.032). At postoperative 6 months, there was no significant difference in the renal function between two groups [serum creatinine level was (126±26) μmol/L vs. (120±28) μmol/L, and the estimated glomerular filtration rate was (56±13) mL/(min·1.73 m²) vs. (60±15) mL/(min·1.73 m²), both P > 0.05]. The allograft and recipient survival rates were 100% in both groups. The incidence of acute rejection within postoperative 1 month was 18% in the Tac-ER group and 3% in the Tac-IR group, with no significant difference (P > 0.05). The overall incidence of adverse events was 94% in the Tac-ER group and 97% in the Tac-IR group, with no significant difference (P > 0.05). Conclusions The efficacy and safety of Tac-ER are equivalent to those of Tac-IR, whereas a higher dose of Tac-ER should be orally given to reach the blood concentration similar to that of Tac-IR. During early-stage drug treatment, Tac-ER should be orally given before kidney transplantation or inittally with loading dose, aiming to increase the systemic exposure to tacrolimus early after kidney transplantation and prevent acute rejection caused by insufficient exposure.

OBJECTIVE: To explore the clinical characteristics and molecular pathogenesis of a child with autosomal dominant polycystic kidney disease (ARPKD). METHODS: Prenatal ultrasound, clinical feature and family history of the child were analyzed. Whole exome sequencing was carried out for the child. Candidate variants were verified by Sanger sequencing. RESULTS: The child has featured premature birth with very low weight, neonatal respiratory distress, metabolic acidosis, and congenital nephrotic syndrome. Gene sequencing revealed that he has harbored compound heterozygous variants of the PKHD1 gene (NM_138694), including c.3885T>A (p.Tyr1295*) in exon 32 and c.7812_7816dupTGATA (p.Thr2606Metfs*63) in exon 49, which were respectively inherited from his mother and father. CONCLUSION The compound heterozygous variants of the PKHD1 gene probably underlay the disease in this child.

Objective: To understand the neglect status among preschool non-only-child in Nantong, and to provide theoretical basis for the prevention and intervention of non-only child neglect. Methods: Using the method of random cluster sampling, a total of 1 141 parents of children from 9 kindergartens in the main urban area of Nantong were investigated with National Neglect Norm Scale for Children aged 3 to 6 years. Results: The neglect rate of preschool children in Nantong City was 28.6%, with neglect score being (40.21±6.67). The neglect rate of non-only-child was 32.6%, with neglect score being (41.14±6.73). The total and physical neglect rate of non-only-child were higher than that of only child, and the total neglect score and physical, emotional, educational, safety, medical neglect dimensional scores were higher than that of only-child, the difference were all statistically significant ( χ 2/ t = 6.21, 17.57; 3.95, 4.98, 3.45, 2.70, 2.01, 3.11, P <0.05). In non-only-child, univariate analysis showed that there were no significant differences in neglect rate and scores among children by gender and family types ( P >0.05); There was no significant difference in the child neglect rate between different age groups and children in different families ( χ 2 =3.59, 2.99, P >0.05), but there was a statistically significant difference in the degree of neglect ( t=2.79, 3.04, P <0.05). The neglect rate and score of non-only-child with high level of family income, parental education and parental relationship was relatively low, while the neglect rate and score in non-only-child whose grandparents serving as primary caregiver were higher ( P <0.05). Multivariate Logistic regression analysis showed that family monthly income less than 5 000 yuan was associated with 2.73 times higher risk of neglect compared to children with family monthly income more than 12 000 yuan. The risk of neglect among children whose grandparents serving as caregivers was associated with 2.17 times higher than children with parental care. The risk of neglect of children with poor parental relationship was 2.29 times higher than that of children with good parental relationship ( P <0.05). Conclusion The neglect among preschool non-only-child in Nantong City is common. Improvement in family economic status, parental care and parent relationship might help reduce neglect among preschool non-only-child.
