Objective: To study the antibacterial activity in vitro of Sanhuang Shaoshangling on several common bacteria after changing the preparation process. Methods:Using the new technology of ethanol reflux extraction and water extraction, Sanhuang Sha-oshangling was prepared. A micro-broth dilution method was used to determine the minimum inhibitory concentration ( MIC) of San-huang Shaoshangling for escherichia coli, pseudomonas aeruginosa, staphylococcus aureus and type B paratyphoid salmonella after chan-ging the preparation process. The antibacterial effect of Sanhuang Shaoshangling prepared by the new and the old technology was com-pared, and the inhibition zone was detected by a paper strip method. Results:The antibacterial effect of Sanhuang Shaoshangling pre-pared by the new technology on escherichia coli, pseudomonas aeruginosa, staphylococcus aureus and type B paratyphoid salmonella was better than that of the products prepared by the old technology with the minimum inhibitory concentration ( MIC) of 16 μg·ml-1 , 16μg·ml-1 , 8 μg·ml-1 and 16 μg·ml-1 , respectively, while that of the product prepared by the old technology was 32 μg·ml-1 , 64 μg·ml-1 , 16 μg·ml-1 and 64 μg·ml-1 , respectively. Conclusion: The antibacterial effect of Sanhuang Shaoshangling after changing the preparation process is more significant, which shows certain clinical significance.

Objective:To observe the perioperative rehabilitation of children undergoing lingual frenoplasty under dexmedetomidine nasal drip combined with esketamine anesthesia.Methods:100 children who underwent lingual frenoplasty in Changsha Maternal and Child Health Hospital from 2020 to 2021 were randomly divided into two groups: the esketamine group (E group, 50 cases) and the dexmedetomidine nasal drip combined with esketamine group (DE group, 50 cases). The mean arterial pressure (MAP), heart rate (HR) , blood oxygen saturation (SpO 2) and respiratory rate (RR) were measured, and the patients were admitted to the post anesthesia recovery unit (PACU) after operation. The modified Aldrete score, Visual Analogue Score (VAS), Wake-up Restlessness Score, food intake (clear water) time and hospital leaving time were observed at 10 min, 30 min, 60 min and 120 min after operation. Results:There was no significant difference in SpO 2 and RR, MAP and HR at T 0 and T 6 between the two groups (all P>0.05). The MAP and HR at T 1, T 2, T 3, T 4 and T 5 in DE group were lower than those in E group (all P<0.05). The modified Aldrete score of DE group was higher than that of E group, and the VAS and Wake-up Restlessness Score were lower than that of E group (all P<0.05); The time of food intake (clear water) and leaving hospital were shorter than those in Group E, with statistically significant difference (all P<0.05). Conclusions:In children′s lingual frenoplasty, dexmedetomidine nasal drip combined with esmketamine can more effectively relieve postoperative pain and agitation than esmketamine alone, shorten children′s postoperative eating time, leave the hospital earlier, and enhance recovery of children.

According to the literature review, no cyst of the hip ligamentum teres has been reported. In this study, a 50?year?old female patient was admitted to the hospital because of sprained left hip pain with movement restriction for 15 months. The unilateral hip joint MRI showed cyst of the hip ligamentum teres, which was diagnosed as left hip joint cyst in the outpatient de?partment. Thus, the patient was admitted to the hospital. Physical examination showed that the left hip joint movement was slightly restricted with positive FADDIR test and FABER test. Arthroscopic surgical examination revealed a 1.5 cm×1.0 cm cyst at the lo?cation of the round ligament which was then cleared with a planer knife and radiofrequency. The treatment results were satisfacto?ry. The present study reviewed the literature about anatomical and biomechanical physicochemical properties of the ligamentum teres. The function of the ligamentum teres is important for the hip joint. In diagnosis of hip disease, unilateral hip MRI plays an important role in accurate diagnosis of such diseases. The hip arthroscopy provide a minimal invasive technique in treating cyst of the hip ligamentum teres. With the application of the hip arthroscopy, it will undoubtedly improve the diagnosis and treatment of hip diseases.

Objective:To evaluate the effect of esmketamine for labor analgesia on the occurrence of postpartum depression (PPD).Methods:Two hundred and forty-two cases of nulliparous parturients who selected natural labor and agreed to receive labor analgesia were selected and divided into conventional labor analgesia group (C-LA group, n=119) and esmketamine-based labor analgesia group (E-LA group, n=123). The epidural labor analgesia solution contained ropivacaine 100 mg and sufentanil 30 μg in 100 ml of normal saline in C-LA group. The epidural labor analgesia solution contained ropivacaine 100 mg, sufentanil 30 μg and esketamine 50 mg in 100 ml of normal saline in E-LA group. The Edinburgh Postnatal Depression Scale (EPDS) was used to screen parturients for depression on admission to the predelivery room and at 2 h and 1, 7 and 42 days after delivery, and EPDS scores were recorded. The patients were diagnosed as having PPD when EPDS score ≥ 9 at 7-42 days after delivery. Peripheral venous blood samples were collected on admission to the predelivery room and at 1 day after delivery to determine the concentrations of serum estrogen, progesterone, 5-hydroxytryptamine and cortisol by enzyme linked inmunosorbent assay. Results:Compared with group C-LA, the EPDS scores were significantly decreased on the 1 and 42 days after delivery( P<0.01), no significant change was found in the incidence of PPD (1.7%/0.8%, P>0.05), no significant change was found in the concentrations of serum estrogen, progesterone, 5-hydroxytryptamine and cortisol on admission to the delivery room ( P>0.05), and the concentrations of serum progesterone and cortisol were significantly increased on 1 day after delivery in group E-LA ( P<0.05). Conclusions:Combination of esketamine is helpful in reducing the risk of postpartum depression when used for epidural labor analgesia, and the mechanism is related to slowing the declines in blood levels of sex hormones and stress hormones after delivery.

Objective:To observe the effect of combination of esketamine and sufentanil on postoperative analgesia and postpartum depression after cesarean section.Methods:A total of 150 primiparous women who underwent lower segment cesarean section under spinal anesthesia and postoperative analgesia at Changsha Maternal and Child Health Hospital from February to October 2021 were selected and randomly divided into three groups: A, B, and C, with 50 cases in each group. All three groups underwent combined spinal epidural anesthesia and received patient-controlled intravenous analgesia (PCIA) after surgery. The group A received low-dose esketamine via intravenous pump after fetal delivery, with PCIA formula esketamine combined with sufentanil; After the delivery of fetuses in the group B and the group C, an equal dose of physiological saline was pumped into the vein. The PCIA formula of esketamine combined with sufentanil for the group B and Sufentanil for the group C. We compared the pain Visual Analogue Scale (VAS) and Edinburgh Postpartum Depression Scale (EPDS) scores of three groups of patients at different time points after surgery, as well as the postoperative pain relief rate and incidence of adverse reactions.Resultsl:There was a statistically significant difference in VAS between the group A and the group B within 48 hours after surgery compared to the group C (all P<0.05), while there was a statistically significant difference in VAS between the group A and the group B within 24 hours after surgery (all P<0.05). The postoperative pain relief rate in the group A and group B was significantly lower than that in the group C, and the incidence of postpartum depression within 7 days after surgery was significantly lower than that in the group C. Moreover, the incidence of postpartum depression in the group A was lower than that in the group B within 3 days after surgery, and the differences were statistically significant (all P<0.05). There was no statistically significant difference in the incidence of postpartum depression among the three groups 42 days after surgery (all P>0.05), and there was no statistically significant difference in the incidence of adverse reactions among the three groups ( P>0.05). Conclusions:Esketamine combined with sufentanil can synergistically enhance the analgesic effect after cesarean section and reduce the incidence of early postpartum depression after surgery.
