Objective To observe the effect of acupoint sticking therapy along meridians on gastrointestinal function recovery in patients after lumbar internal fixation surgery.Methods From January 2020 to March 2022,125 patients with lumbar degenerative diseases were admitted to our hospital's Department of Orthopaedics and divided into two groups:control(n = 62)and acupoint sticking therapy(n = 63).The control group received standard postoperative care for lumbar internal fixation,while the experimental group received routine care based on acupoint sticking therapy along meridians.The NVAS scores for postoperative nausea and vomiting,abdominal distension and pain,bowel sound,initial exhaust,and defecation time were compared between the two groups.Results Both groups experienced gastrointestinal problems to varied degrees following surgery.The experimental group had signifi-cantly lower rates of nausea,NVAS score,vomiting grade,abdominal distension,return to normal bowel sounds,and time of first exhaust and bowel movement compared to the control group(P<0.05).However,there were no significant differences in abdominal pain and abdominal circumference(P>0.05).There were no adverse reactions in either group.The incidence of postoperative abdominal distension,nausea and vomiting in the observation group was lower than that in the control group,and the difference was statistically significant(P<0.05).Conclusion Acupoint sticking therapy along meridians could accelerate the recovery of gastrointestinal function of patients after lumbar internal fixation,promote rapid recovery after surgery,and improve quality of life.

【Objective】 To analyze the basic characteristics of whole blood donors from blood stations before and after the outbreak of COVID-19. 【Methods】 After excluding invalid data, data related to the basic characteristics of whole blood donors collected from 26 blood stations in China during 2018 to 2021 were statistically analyzed, including the trend of total whole blood donors, the number of repeated blood donors, the frequency of blood donation, the average age of donors and the recruitment of first-time blood donors. 【Results】 Affected by the epidemic, 8 out of 14 indicators were with large variations, accounting for 57%. The overall growth rate of total whole blood donors during the epidemic was higher than before the epidemic (P<0.05).The number of repeated blood donors has shown an increased trend, with a higher number during the epidemic than before (P<0.05). The frequency of blood donation was lower during the epidemic than before(P<0.05).Average ages of blood donors and female blood donors fluctuated widely during the epidemic, both higher than those before the epidemic(P<0.05).The donation rate of first-time blood donors <25 years old and ≥25 years old varied widely and irregularly during the epidemic (both P<0.05). The percentage of first-time blood donors fluctuated irregularly during the epidemic, with overall percentage lower than that before the epidemic(P<0.05). 【Conclusion】 Whole blood donors from 26 blood stations increased after the outbreak of COVID-19, and some indicators in certain areas showed significant fluctuations during the epidemic.

In the context of shortage of donor livers, split liver transplantation has achieved the goal of "one donor liver for two recipients", which effectively alleviates the shortage of donor livers and has promising development prospect. With the advancement of liver transplant techniques, split liver transplantation may yield clinical prognosis equivalent to total liver transplantation. However, perioperative management of split liver transplantation still encounters multiple challenges, with demanding techniques requirement and high-risk postoperative complications. Besides, there is a possibility of dividing one high-quality donor liver into two marginal donor livers, which will affect the development of liver transplantation. In this article, perioperative management of split liver transplantation was discussed from the perspectives of preoperative evaluation, recipient management and postoperative complication management, aiming to provide reference for promoting the development of split liver transplantation and enhancing clinical prognosis of recipients after split liver transplantation.

Objective:To observe the results of electroacupuncture (EA) on the resuscitation of a rat model of asphyxia cardiac arrest (CA). And to explore its effect on the neurologic deficits and hemodynamic instability of post-cardiac arrest syndrome (PCAS).Methods:A total of 107 male SD rats were randomly divided into sham, CA, and EA groups. Each group received arterial catheterization and tracheal intubation. The sham group was not induced asphyxia. Asphyxial cardiac arrest was established by endotracheal tube clamping. Rats in the CA group received basic respiratory support and fluid resuscitation in return of spontaneous circulation (ROSC) and rats in the EA group received EA at Baihui based on the treatment of CA group after ROSC, with a dense-dispersed wave at frequencies of 4-20 Hz, while the current intensity was adjusted minimum to induce a twitch of the scalp, the course of treatment was 30 minutes. The baseline data, hemodynamics after ROSC, neurological deficit score (NDS), pathological changes of brain tissue, and levels of serum biomarker were recorded and compared among the three groups. The 72-hour survival of rats was analyzed by Kaplan-Meier survival curve. Hematoxylin-eosin (HE) staining was used to observe the pathological changes of necrotic neurons in the hippocampal CA1 region of rat brain. Meanwhile, Nissl staining and TdT-mediated dUTP nick-end labeling (TUNEL) were used to detect cell apoptosis and injury.Results:Compared with the CA group, the mean arterial pressure (MAP) in the EA group increased significantly at 15 minutes after ROSC [mmHg (1 mmHg≈0.133 kPa): 125.00 (94.00, 136.25) vs. 92.00 (72.00, 122.50), P < 0.05]. There was no significant difference in the NDS score between the EA group and the sham group. Still, the NDS score of the rats in the CA group at 6 hours after ROSC were significantly lower than that in the sham group (46.00±10.61 vs. 80.00±0.00, P < 0.05). Kaplan-Meier survival curve analysis showed that EA did not improve the 72-hour survival rate of rats (100% in the sham group, 25% in the CA group, and 30% in the EA group, P > 0.05). The analysis by TUNEL showed that the apoptosis rate of neurons in CA1 region of the hippocampus in EA group at 6 hours after ROSC was significantly lower than that in CA group [(62.84±2.67)% vs. (71.29±3.70)%, P < 0.05]. Compared with the CA group, the level of serum S100 calcium binding protein B (S100B) in the EA group at 6 hours after ROSC was significantly lower (ng/L: 19.30±13.87 vs. 132.28±31.67, P < 0.05), but there were no significant differences in the levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) between these two groups. Conclusions:In the present study, EA at Baihui can stabilize the hemodynamic, moreover, it has a particular neuroprotective effect on PCAS rats. Still, EA at Baihui does not reduce the systemic inflammatory response and improve the survival rate of rats, and its mechanism remains to be verified in further research.

Objective To summarize the experience of organ donation after citizen' s death during the novel coronavirus pneumonia (COVID-19) epidemic. Methods Eleven cases of potential donors of organ donation after citizen' s death during the COVID-19 epidemic were retrospectively analyzed, and the workflow and key points of infectionprevention and control were summarized. Results Among 11 cases of potential donors, 6 cases failed to implement organ donation. Five donors who were successfully performed organ donation had no respiratory symptoms before the onset of encephalopathy. CT scan of the lungs upon the onset of encephalopathy showed that one case was diagnosed with aspiration pneumonia, and the remaining four cases obtained negative results. During hospitalization, all of the 5 donors showed fever symptom and repeated chest CT scan detected lung inflammation. Bronchoalveolar lavage fluid or blood samples tested for novel coronavirus nucleic acids were all negative. No confirmed or suspected cases appeared among all staff and recipients who were in close contact with organ donors. Conclusions Targeted formulation of the workflow and prevention and control measures, in combination with selection and implementation of infection risk classification can effectivelyreduce the risk of COVID-19 infection and carry out organ donation after citizen' s death in a safe and organized manner.

Objective: To explore mechanism of lung injury of rats induced by inhalation of white smoke from burning smoke pot. Methods: Forty-eight Sprague Dawley rats were divided into control group (n=12) and injury group (n=36) according to the random number table. Rats in injury group were placed in smoke-induced injury experimental equipment fulled with white smoke from burning smoke pot for 5 minutes to make lung injury, and rats in control group were placed in smoke-induced injury experimental equipment fulled with air for 5 minutes to make sham injury. Six rats in injury group at post injury hour (PIH) 6, 24, and 72 and six rats in control group at PIH 72 were collected to observe pathological changes of lung tissue and pathological score of rats in the two groups by hematoxylin-eosin staining, to detect expression of nuclear factor-κB (NF-κB) p65 mRNA in lung tissue of rats by reverse transcriptional polymerase chain reaction, and to detect content of tumor necrosis factor α (TNF-α), interleukin 1β (IL-1β), and IL-6 in lung tissue of rats by enzyme-linked immunosorbent assay. Data were processed with one-way analysis of variance and t test. Results: At PIH 72, lung tissue structure of rats in control group was clear and complete, with no inflammatory cell infiltration. At PIH 6, there was edema, hemorrhage, and inflammatory cell infiltration in lung tissue of rats in injury group. At PIH 24, edema, hemorrhage, and inflammatory cell infiltration in lung tissue of rats in injury group aggravated. At PIH 72, area of edema in lung tissue of rats in injury group was enlarged, with obvious hemorrhage and inflammatory cell infiltration. At PIH 6, 24, and 72, pathological score of lung tissue of rats in injury group was (3.43±0.86), (5.39±0.93), and (9.99±0.84) points, respectively, obviously higher than that of rats in control group at PIH 72 [(2.11±0.20) points, t=3.659, 8.450, 22.355, P<0.05]. As time post injury prolonged, pathological scores of lung tissue of rats in injury group were significantly increased (F=121.244, P<0.01). At PIH 6, 24, and 72, expression of NF-κB p65 mRNA in lung tissue of rats in injury group was 15.5±4.3, 25.9±1.8, 30.9±3.5 respectively, significantly higher than that of rats in control group at PIH 72 (7.8±0.8, t=4.315, 20.445, 14.408, P<0.01). As time post injury prolonged, expression of NF-κB p65 mRNA in lung tissue of rats in injury group gradually increased (F=32.691, P<0.01). At PIH 6, 24, and 72, content of TNF-α, IL-1β, and IL-6 in lung tissue of rats in injury group was significantly higher than that of rats in control group at PIH 72, respectively (t=7.650, 8.968, 6.827, 6.726, 8.978, 3.460, 5.420, 13.289, 16.438, P<0.01). At PIH 24, content of TNF-α and IL-1β in lung tissue of rats in injury group was higher than that of rats in the same group at PIH 6 and 72, respectively (t=3.409, -2.549, 4.047, -4.100, P<0.05). At PIH 24 and 72, content of IL-6 in lung tissue of rats in injury group was respectively higher than that of rats in the same group at PIH 6 (t=8.273, 9.711, P<0.05). Conclusions After inhaling white smoke from burning smoke pot, rats are inflicted with lung injury by increasing expression of NF-κB p65 mRNA and content of TNF-α, IL-1β, and IL-6, and induce pathological changes of edema, hemorrhage, and inflammatory cell infiltration of lung tissue.

Objective To explore the effect of Jianbu-Huqian ointment combined with proximal femoral nail antirotation for the elderly patients with intertrochanteric fracture of femur with osteoporosis. Methods A total of 85 elderly patients with intertrochanteric fracture of femur with osteoporosis were randomly divided into the control group (40 patients) and the observation group (45 patients. Both groups of patients were treated with proximal femoral nail antirotation, and the observation group was added with Jianbu-Huqian ointment. The pain, fracture healing, joint function, bone mineral density and complications were compared between the two groups. Results The VAS pain score at 1st week (6.2 ± 1.6 vs. 7.9 ± 1.6; t=3.683, P<0.05), 3rd week (3.1 ± 1.1 vs. 5.4 ± 1.4; t=4.239, P<0.05) and 7th week (2.3 ± 0.9 vs. 4.0 ± 1.3; t=3.571, P<0.05) after operation of the observation group were significantly lower than those of the control group. The occurrence time (42.4 ± 5.9 d vs. 49.2 ± 6.2 d; t=4.139, P<0.05), walking time (6.9 ± 1.1 weeks vs. 8.7 ± 1.2 weeks;t=3.695, P<0.05), fracture healing time (13.9 ± 2.2 weeks vs. 16.2 ± 3.1 weeks, t=3.473, P<0.05) of the observation group were significantly lower than those of the control group. Harris hip score (89.8 ± 7.21 vs. 81.4 ± 5.93; t=3.728, P<0.05) in the observation group was significantly higher than that in the control group. The bone density of the femur (0.782 ± 0.142 g/cm2 vs. 0.691 ± 0.135 g/cm2; t=3.759, P<0.05) and the area of ward (0.628 ± 0.071 g/cm2 vs. 0.513 ± 0.059 g/cm2; t=4.386, P<0.05) of the observation group were significantly lower than those of the control group. The incidence of postoperative complications in the observation group was 15.0%(6/40), and the control group was 37.8% (17/45). The difference was statistically significant (χ2=5.567, P<0.05). Conclusions The Jianbu-Huqian ointment combined with proximal femoral nail antirotation could reduce the pain, promote fracture healing, and prevent the occurrence of postoperative complications for the elderly patients with intertrochanteric fracture of femur with osteoporosis.

Objective To observe the effect of acupuncture on cystathionine gamma-lyase(CSE)and myeloperoxidase (MPO) in the colonic tissues of rats and to explore its mechanism for recovering the function of interstitial cells of Cajal(ICCs)in rats after colonic anastomosis . Methods Thirty SD rats were randomized into normal control group, model group(receiving colonic anastomosis) and acupuncture group. The acupuncture group received foot three-needle therapy on bilateral Zusanli(ST36), Sanyinjiao(SP6) and Taichong(LR3), once a day for 3 days after colonic anastomosis. And then the propulsive rate of the small intestine was measured. The count of ICCs with positively expressive c-kit in rat colonic tissues was measured by immunohistochemistry, the activity of CSE was observed by enzyme-linked immunosorbent assay (ELISA) and the activity of MPO was tested by biochemical method. Results Compared with the normal control group, the small intestinal propulsive rate in the model group was decreased, the number of ICCs with positively expressive c-kit was reduced, while the activities of CSE and MPO were increased(P<0.05). The acupuncture group had higher intestinal propulsive rate, more ICCs with positively expressive c-kit, and lower CSE and MPO activities than the model group(P<0.05).Conclusion Acupuncture can promote the recovering of postoperative gastrointestinal function, and its mechanism may be related to the regulation of CSE and MPO activities in the colonic tissues and to the restoration of ICCs function in the focus with positive c-kit.

OBJECTIVETo evaluate the effect of techniques of precise liver surgery for donor hepatectomy in living donor liver transplantation.

METHODSEighty-nine donors aged from 19 to 57 years were performed by the same surgical team from June 2006 to December 2013 in Chinese People's Liberation Army General Hospital.Individualized surgical program were developed according to preoperative imaging examination and hepatic functional reserve examination. The evaluation included liver function, liver volume, vascular anatomy and bile duct anatomy. According to the results after the operation, preoperative evaluation accuracy, postoperative donor liver function and postoperative complications were analyzed. ANOVA analysis was used to compare the difference of graft volume by two-dimensional, three-dimensional calculation method and actual postoperative graft weight. Pearson correlation test and linear regression analysis were used to verify the correlation between the estimated graft volume each method and actual graft postoperative weight.

RESULTSAll the 89 cases operation protocol as following, there were 5 cases with left lateral lobe graft, 10 cases with left lobe liver graft, 74 cases with right lobe graft. There were 59 cases with middle hepatic vein (MHV) harvested, and 30 cases without MHV. The mean graft volume by two-dimensional, three-dimensional calculation method and actual postoperative graft weight were (656.2±134.1) ml, (631.7±143.2) ml and (614.5±137.7) ml respectively. ANOVA analysis results showed that there were no statistically significant difference in the three methods (P>0.05). Compared to the actual postoperative graft weight, the average error rate of the two methods were 7.9% and 5.3% respectively. Pearson correlation test showed the graft volume calculated by two-dimensional and three-dimensional methods had a significantly positive correlation with actual graft weight (r=0.821, 0.890, P<0.01) and linear regression analyze showed the R2 were 0.674 and 0.792, respectively. The accuracy rate of preoperative evaluation about portal vein, hepatic vein, hepatic artery and bile duct were 100%, 100%, 97.8% and 95.5%, respectively. The preoperative plan and postoperative practical scheme coincidence rate was 95.5%. Overall donor complication rate was 7.4%. All donors were alive. Sixteen donors received right lobe hepatectomy with gallbladder preserved had a good liver function and gallbladder function.

CONCLUSIONThrough the precise preoperative evaluation, surgical planning, fine operation and excellent postoperative management, precise liver surgery technique can ensure the safety of donor in living donor liver transplantation.
