Objective:To investigate the analgesic effect of ultrasound-guided transversus abdominis plane block versus ultrasound-guided quadratus lumborum block in older adult patients undergoing inguinal hernia repair surgery. Methods:A total of 150 older adult patients who underwent inguinal hernia repair surgery at the Marine Police Corps Hospital of Chinese People's Armed Police Force from April 2019 to May 2022 were included in this study. They were randomly divided into a control group ( n = 75) and a study group ( n = 75) using a random number table method. All patients underwent elective laparoscopic tension-free inguinal hernia repair surgery. Patients in the control group received ultrasound-guided transversus abdominis plane block after inguinal hernia repair surgery, while those in the study group received ultrasound-guided quadratus lumborum block. The changes in Visual Analog Scale (VAS) score and Ramsay score within 48 hours after surgery were compared between the two groups. Inflammatory factors and stress factors including serum tumor necrosis factor alpha, interleukin-6, norepinephrine, and cortisol, were measured at 24 and 48 hours after surgery. The use of analgesics, drug-related adverse reactions, and incidence of nerve block-related complications within 48 hours after surgery were also compared between the two groups. Results:There was no significant difference in Ramsay score between the two groups at 4, 8, 12, 24, and 48 hours after surgery (all P > 0.05). There was no significant difference in VAS score between the two groups at 4 and 8 hours after surgery (both P > 0.05). At 12, 24, and 48 hours after surgery, the VAS score in the study group was (1.36 ± 0.57) points, (2.05 ± 0.56) points, and (1.79 ± 0.55) points, respectively, which were significantly lower than (1.92 ± 0.59) points, (2.68 ± 0.62) points, and (2.36 ± 0.59) points in the control group ( t = 6.65, 7.31, 5.86, all P < 0.001). At 24 and 48 hours after surgery, serum tumor necrosis factor alpha, interleukin-6, norepinephrine, and cortisol levels in the study group [24 hours: (63.89 ± 4.65) ng/L, (156.59 ± 8.62) ng/L, (97.02 ± 6.95) g/L, (36.95 ± 3.26) g/L; 48 hours: (49.66 ± 3.74) ng/L, (131.45 ± 7.73) ng/L, (74.63 ± 5.91) g/L, (30.41 ± 2.96) g/L] were significantly lower than those in the control group [24 hours: (76.42 ± 5.17) ng/L, (189.32 ± 10.41) ng/L, (105.53 ± 7.83) g/L, (45.16 ± 3.74) g/L; 48 hours: (58.15 ± 3.94) ng/L, (162.74 ± 8.49) ng/L, (89.51 ± 6.37) g/L, (36.92 ± 3.31) g/L, t = 10.49-26.38, all P < 0.001]. The proportion of patients who received analgesics within 48 hours after surgery in the study group was 8.00% (6/75), which was significantly lower than 25.33% (19/75) in the control group ( χ2 = 8.11, P = 0.004). The overall incidence of drug-related adverse reactions within 48 hours after surgery in the study group [6.67% (3/75)] was significantly lower than that in the control group [11% (11/75), χ2 = 4.61, P = 0.032]. Conclusion:Compared with ultrasound-guided transversus abdominis plane block, ultrasound-guided quadratus lumborum block better helps alleviate postoperative pain in older adult patients undergoing inguinal hernia repair surgery, inhibits inflammation and stress reactions, reduces the dosage of analgesic drugs, and decreases the incidence of adverse drug reactions.

The complexity of coding surgical procedures related to renal replacement therapy in nephrology stems from a deficiency in clinical knowledge regarding renal replacement therapies and an incomplete understanding of the classification rules within the ICD-9-CM-3 coding system.This paper delves into the clinical aspects of renal replacement therapy and organizes the corresponding coding classification rules,clarifying the codes for various treatment modalities.For instance,the establishment of dialysis access is coded as 38.95 for hemodialysis venous intubation,39.27 for vascular fistula,and 54.93 for peritoneal dialysis intubation via a cutaneous peritoneal stoma.Maintenance hemodialysis is coded as 39.95,while peritoneal dialysis is coded as 54.98.The removal of dialysis catheter is differentiated into surgical and non-surgical;surgical removal is coded as 86.05,and non-surgical removal as 97.86 or 97.89.For instances of internal fistula stenosis or thrombosis,balloon dilation is coded as 39.50.Stent implantation for stenosis or isolation of a false aneurysm is coded as 39.90 for bare stent,and 00.55 for covered stents.The resection and reconstruction involving stenosis,thrombus segments,or false aneurysms,are coded as 39.42.This classification aims to improve the accuracy of coding for such procedures.

Objective By analyzing the main diagnostic choices of inpatient records in obstetrics and the problems exist-ing in ICD codes,we can improve the quality of the main diagnostic choices and coding in obstetrics.Methods A total of 205 obstetric inpatient medical records were randomly selected from a hospital from January 1 to April 30,2024,and the medical re-cords were checked jointly by three senior coders,and the errors were summarized and analyzed by using the check table.Results Among 205 obstetrical medical records,72(35.12％)were found to have errors in the selection and coding of major diagnoses;among them,there were 55 cases of incorrect selection by clinician and incorrect compilation by coders,13 cases of correct selection by clinician,incorrect compilation or omission by coders,4 cases of omission by clinician and omission by cod-ers.Conclusion The selection and coding of the main diagnosis in obstetrics are very special and difficult,so the training of cli-nicians should be strengthened,the writing of clinicians should be standardized,and the importance of the main diagnosis selec-tion should be strengthened.At the same time,strengthen the management of coders,standardize the coding operation process,strengthen the learning of professional knowledge,improve professional reserves,strengthen the two-way communication with cli-nicians,and jointly improve the main diagnosis selection and coding accuracy rate of obstetrics,so as to ensure the quality of data on the first page of obstetric inpatient medical records.

Objective:To investigate the clinical efficacy of different enteral nutrition methods combined with swallowing rehabilitation training in the treatment of Alzheimer's disease complicated by dysphagia.Methods:A total of 120 patients with Alzheimer's disease and dysphagia who received treatment in the Department of Geriatric Medicine, the Second Hospital of Jinhua from October 2019 to March 2021 were included in this study. They were randomly and evenly divided into four groups: A, B, C, and D. Patients in groups A, B, C, and D were given nasogastric tube feeding, naso-intestinal tube feeding, nasogastric tube feeding + swallowing rehabilitation training, and naso-intestinal tube feeding + swallowing rehabilitation training, respectively. After 12 weeks of treatment, total response rate, nutritional status, and complications were compared between the four groups.Results:After 12 weeks of treatment, total response rate in group D was the highest (100.0%), which was significantly higher than that in the other three groups (group A: 13.3%; group B: 40.0%; group C: 73.3%; χ2 = 45.88, 25.71, 9.23, all P < 0.05). After treatment, the nutritional status [body mass index (BMI): (21.42 ± 1.85) kg/m 2, (23.17 ± 2.03) kg/m 2] and patient satisfaction (60.0%, 100.0%) in groups C and D were significantly superior to those in group A [BMI: (19.01 ± 1.72) kg/m 2; patient satisfaction: 10.0%) and group B [BMI: (19.86 ± 1.69) kg/m 2; patient satisfaction: 33.3%]. Group D had the best nutritional status ( t = 7.01, 5.14, 1.78, all P < 0.05) and the highest patient satisfaction ( χ2 = 49.09, 30.00, 15.00, all P < 0.001). Conclusion:Naso-intestinal tube feeding combined with swallowing rehabilitation training is the best treatment for Alzheimer's disease complicated by dysphagia among the studied enteral nutrition feeding methods and therefore deserves clinical promotion.

Objective:To investigate the analgesic effects of Dexmedetomidine combined with Ropivacaine for abdominal fascia block(AFB, with transverse abdominis plane block and rectus abdominis sheath block)in elderly patients undergone open surgery for colon cancer.Methods:This was a prospective study.Fifty elderly patients following ASA Ⅰ-Ⅲ open surgery for colon cancer were randomly divided into Group R and Group RD.Patients in Group R were treated with Ropivacaine for AFB, and those in Group RD were given Dexmedetomidine 0.5 μg/kg and Ropivacaine.All patients received Morphine-based patient-controlled intravenous analgesia(PCIA)after surgery.The total dose of postoperative Morphine, the time to first required use of Morphine, and the visual analog score(VAS)at 4, 8, 16, and 24 h after surgery were compared between the two groups.Results:Compared with Group R, patients in Group RD were associated with a significantly decreased total amount of Morphine at 24 h after surgery [25(20-32)mg vs.30(22-38)mg, Z=5.00, P<0.001], a lower VAS at 4 h [17(15-19) vs.36(23-39), Z=23.04, P<0.001]and 8 h after surgery [20(18-22) vs.41(38-55), Z=25.47, P<0.001], a longer time to first required use of Morphine [233(204-256)min vs.183(167-195)min, Z=4.367, P<0.001], and less postoperative nausea and vomiting(20.0% vs.48.0%, P=0.037). Conclusions:For elderly patients after colon cancer surgery, transverse abdominis plane and rectus sheath block with Dexmedetomidine plus Ropivacaine can enhance the analgesic effect, prolong the time of effective analgesia, reduce the amount of Morphine used postoperatively, and is beneficial for early recovery.

The higher levels of the knowledge and attitude of salt reduction for hypertension prevention,the higher level of the practice.

Objective To evaluate the effect of partial neuromuscular blockade (NMB) on the efficacy and safety of nerve monitoring during microvascular decompression (MVD) of facial nerve.Methods Seventy American Society of Anesthesiologists physical status Ⅰ or Ⅱ patients of both sexes,aged 39-78 yr,weighing 44-84 kg,scheduled for elective MVD,were divided into 2 groups (n=35 each) using a random number table method:control group and partial NMB group.Anesthesia was induced by intravenous injection of 3-fold ED95 cisatracurium.In control group,muscle relaxants were not used after intubation.In partial NMB group,cisatracurium was continuously infused intravenously to maintain partial NMB,and the T1/Tc ratio was maintained at 20％-40％.Intraoperative neuroelectrophysiological monitoring was performed using lateral spread response (LSR).The success rates of LSR monitoring,occurrence of body movement,requirement for anesthetics and cardiovascular agents were recorded during operation,and the patients were followed up on day 7 after surgery,and the therapeutic efficacy and occurrence of neurological complications were recorded.Results Compared with control group,the incidence of intraoperative body movement was significantly decreased,the intraoperative consumption of propofol and remifentanil was decreased,and the intraoperative requirement for vasopressors was decreased in partial NMB group (P＜0.05).There was no significant difference in the success rate of LSR monitoring,therapeutic efficacy and incidence of neurological complications between two groups (P＞0.05).Conclusion Partial NMB (T1/Tc=20％-40％) can be effectively used for MVD monitored by LSR,decrease the occurrence of the body movement,and raise the perioperative safety in patients.

Objective:To elucidate the factors influencing the differences in the survival rates of esophageal squamous cell carcinoma (ESCC) patients between the rural and urban regions in China. Methods:A total of 36,723 ESCC patients derived from the clinical data-bases containing 500,000 esophageal and gastric cardia carcinoma cases (1973-2015) of the Henan Key Laboratory for Esophageal Can-cer Research of the First Affiliated Hospital, Zhengzhou University, were analyzed. Of these patients, 33,625 were from the rural re-gions (91.6%), comprising 20,906 male patients with an average age of 58.98 ± 8.71 years and 12,719 females with an average age of 59.59 ± 8.53 years. The remaining 3,098 were from the urban regions and composed of 2,089 male patients with an average age of 60.84±9.10 years and 1,009 females with an average age of 62.46 ± 9.14 years. All the patients underwent radical esophagectomy, de-tailed histopathological diagnosis, and TNM staging. Chi square test, Kaplan-Meier, Log-rank, and Cox proportional hazards regression model were used to analyze the differences between ESCC patients from rural regions and those from urban regions and among the risk factors in prognosis. Results:Kaplan-Meier and Log-rank analysis results showed that the ESCC patients from the rural regions had significantly higher overall survival than the urban patients (χ2=12.971, P=0.000). Further analysis showed that rural patients≥50 years old and diagnosed with stage IIa and IIb (middle stage) ESCC had higher survival rates than urban patients in males and females (male:χ2=16.188, P<0.001;female:χ2=5.019, P=0.025). However, the survival rates of rural and urban patients with stage 0,Ⅰa,Ⅰb (early stage) and Ⅲa, Ⅲc, and Ⅳ (late stage) were similar (P>0.05). The results of Cox proportional hazards regression model analysis showed that age, gender, and TNM stages were independent risk factors for rural and urban ESCC patients. When the rural and urban ESCC patients were both considered, the Cox proportional hazards regression model analysis results showed that male ESCC patients≥50 years old, urban residence, and TNM stages were independent risk factors. Conclusion:Rural ESCC patients have significantly high-er overall survival than urban patients. Male, age of≥50 years old, urban residence, and TNM stages were independent risk factors for ESCC patient survival.
