ABSTRACT
Objective:To evaluate the value and effectiveness of the enhanced recovery after surgery (ERAS) theory in orthopedic surgery, and to provide a theoretical basis for optimizing rehabilitation plans during the perioperative period of orthopedic surgery.Methods:Relevant literature on the application of accelerated rehabilitation in orthopedic perioperative period officially published in Pubmed and the Chinese Medical Journal Database From January 2000 to October 2022 was searched and included in randomized controlled and clinical case studies. The patients were divided into the experimental group (ERAS group) and the control group (conventional treatment group). The patients in the experimental group were treated with ERAS mode after surgery, while the patients in the control group were treated with conventional rehabilitation mode after surgery. The hospital stay, postoperative complications, postoperative nausea and vomiting, and postoperative incidence rate of deep vein thrombosis in the two groups were statistically analyzed.Results:Finally, a total of 1 301 patients were included in 9 articles, divided into an experimental group (ERAS group, n=643) and a control group (conventional treatment group, n=652). There was a statistically significant difference in hospital stay between the experimental group and the control group ( MD=-4.11, 95% CI: -6.73 to -1.49, P=0.002); The overall effect tendency of the incidence of complications between the experimental group and the control group was statistically significant ( P=0.005); Compared with the control group, the incidence rate of postoperative nausea and vomiting in the experimental group was lower ( P=0.04); The incidence rate of postoperative deep vein thrombosis in the experimental group was lower than that in the control group ( P=0.02). Conclusions:The application of accelerated rehabilitation concept in orthopedic surgery patients can reduce the length of hospital stay, and reduce the incidence rate of postoperative complications, nausea and vomiting, and deep vein thrombosis.

ABSTRACT
Objective To investigate the correlation of clinicopathological parameters and prognosis with serum and pancreatic cancer tissue klotho. Methods Immunohistochemistry EnVision two step method was used to assess klotho protein expression of a tissue microarray ( TMA) of 79 pairs of pancreatic tissue and normal surrounding tissue. The serum klotho levels in 39 pancreatic cancer patients and 39 healthy controls who had matched clinical data were measured by ELISA. The relationships between the expression of klotho and the clinicopathological features and survival were analyzed. Results Klotho expression positivity in pancreatic cancer tissue was significantly higher than that in adjacent normal tissues (59. 5％ vs 96. 3％);serum level of klotho was markedly higher in pancreatic cancer patients than that in control group [(670. 30 ± 82. 24)pg/ml vs (310.35 ± 34.65) pg/ml], and both the difference was statistically significant (P<0.001). Klotho expression was negatively associated with tumor clinical stage and lymph node metastasis (P<0. 05), and the expression of klotho did not correlate with patients' gender, age, tumor size, location, local invasion depth and the like. The median survival time in pancreatic cancer patients with positive klotho expression were longer than that in in pancreatic cancer patients with negative klotho expression [(48. 31 ± 6. 94) months vs (19. 50 ±6. 78)months], and the difference was statistically significant (P<0. 01). ROC analysis on serum klotho gave a cutoff value of 376. 51 pg/ml to diagnosis pancreatic cancer with a sensitivity of 84. 6％ and specificity of 87. 2％. Conclusions Klotho level in serum and tissue of pancreatic cancer patients was closely correlated with clinicopathological parameters and prognosis, which may be a potential biomarker for pancreatic cancer.
ABSTRACT
Objective@#To study the sedative efficacy and safety of nitrous oxide (N2O ) inhalation combined with oral midazolam in children with impacted supernumerary teeth for extraction under sedation and to provide a reference for the selection of anesthetic methods for children undergoing impacted teeth extraction.@*Methods @#Sixty patients aged 5-10 years with maxillary impacted supernumerary teeth were randomly divided into three groups, with 20 in each group, as follows: the N2O group: N2O inhalation sedation before the operation; the midazolam group: oral midazolam sedation before the operation; the combination group: N2O inhalation combined with oral midazolam sedation before the operation. Sedation was performed before extraction under local anesthesia. The Ramsay sedation effect, Houpt behavioral score and incidence of adverse reactions were evaluated after the operation.@*Results@#The Ramsay sedation scale score was significantly higher in the combination group (2.75 ± 0.55) than in the N2O group (2.30 ± 0.47) and the midazolam group (2.40 ± 0.50) (P ＜0.05). Similarly, the Houpt behavioral rating scale score was significantly higher in the combination group (5.25 ± 0.64) than in the N2O group (4.70 ± 0.73) and the midazolam group (4.80 ± 0.69) (P ＜0.05). The adverse reaction rate was lower in the combination group (5%) than in the N2O group (10%) and the midazolam group (10%), but the difference was not significant (χ2=0.436, p=0.804).@*Conclusion@#N2O inhalation combined with oral midazolam sedation in the extraction of impacted supernumerary teeth in children can significantly improve the sedative and therapeutic efficacy and is a safe and effective sedation method.
ABSTRACT
Bioassay-guided fractionation of an ethanolic extract of Ochrosia borbonica led to the isolation of two known pyridocarbazole alkaloids, ellipticine (1) and 9-methoxyellipticine (2), and six known monoterpenoid indole alkaloids (3-8). Lipid-lowering assay in 3T3-L1 cell model revealed that 1 and 2 could significantly inhibit the lipid droplet formation (EC = 0.41 and 0.92 μmol·L, respectively) and lower triglyceride levels by 50%-60% at the concentration of 1 μmol·L, being more potent than the positive drug luteolin (EC = 2.63 μmol·L). A mechanistic study indicated that 1 and 2 could intercalate into supercoiled DNA, which consequently inhibited the mitotic clonal expansion of 3T3-L1 cells at the early differentiation phase, leading to the retardance of following adipogenesis and lipogenesis. These findings suggest that 1 and 2 may serve as promising leads for further development of anti-obesity drugs.

ABSTRACT
Objective To analyze the curative effect of fossa intercondyloidea of micro-fracture and comminution of subcutaneous fat pad on meniscal tear healing under arthroscopy. Methods During the clinical operation, the samples of the micro-fracture and fat pad comminution were attracted to the outside of the joint. The source and properties of cells were identified based on preclinical medicine experiment in vitro. In clinical research, 75 cases of the simple meniscus injury were selected from January 2014 to January 2016 and divided into three groups refer to treatment: Group A, B and C. Different treatments were used in the three groups. Group A - micro-fracture group; Group B - fat pad group; Group C - blank group. All patients' conditions were assessed with Lysholm, VAS score and adverse event (Swelling, anterior knee pain). Results In the preclinical medicine experiment, cells released by micro fracture were fibroblast-like cells which tend to grow more rapidly in vortex shape. Cells released by comminution of fat pad contained a small amount of impurities and necrotic cells and are mostly similar to fibroblast in long spindle shape. Besides, the Human MSC Analysis Kit was used to authenticate two cells which were considered to be as BMSCs and IPFPSCs. In clinical research, all patients received an average of 10 (8 ～ 11) months follow-up visit. No severe complication, such as blood-vessel and nerve injury, infection occurred after operations in the patients followed. Before receiving the treatment, difference in Lysholm, VAS score and general condition of joint of Group A and B, C showed no statistical difference (P > 0.05). Compared with those before operation and after operation in both of four groups, the Lysholm and VAS score were improved (P < 0.05). Besides, there had significantly difference between group A and C, B and C after post treatment in Lysholm and VAS score (P < 0.05), however, group A and B did not. Compared group A and C, the early prevalence of adverse event of group B was higher, but last follow-up show no difference between three groups. Conclusion Combined with basic experimental and clinical studies, our research suggest that micro-fracture and comminution of fat pad have good effect on the repair of meniscus injuries. Nevertheless, it should be concerned that early prevalence of increased swelling amd anterior knee pain of comminution of fat pad.
ABSTRACT
Objective To compare the curative effect of fixation of adolescent tibial intercondylar emi-nence fracture among suture anchor,hollow screw and wire. Methods Forty-six adolescent cases of the tibial intercondylar eminence fracture treated with surgical treatment were selected from January 2010 to June 2016 and divided into three groups refer to intra-operative fixation suture anchor group(Group A),hollow screw group (Group B)and wire group(Group C).Duration of treatment,total operation time,hospital stay and surgery times were recorded. All patient condition was assessed with the Lysholm,Tegner,IKDC and VAS score. Results All patients received an average of 13(11~14)months follow-up visit. No blood-vessel,nerve and osteoepiphysis injured,infection and fracture displacement occurred.Before receiving treatment,difference in Lysholm,Tegner, IKDC and VAS score of group A,B and C showed no statistical difference.When it comes to hospitalization condi-tion,data were as follows.Group A/B/C:operation time(80.67 ± 16.68/114.00 ± 20.28/111.88 ± 20.07)min, hospital stay(8.40 ± 1.12/ 15.47 ± 1.25/ 15.19 ± 1.17)d,surgery times(1/2/2)times. Moreover,compared with those before operation and after operation in both of groups,the Lysholm,Tegner,IKDC and VAS score were improved(P < 0.05). Besides,the Lysholm,Tegner,IKDC and VAS score of group A,B and C did not have statistically significant difference yet after post treatment(P>0.05).Conclusions The curative effect of fixation of adolescent tibial intercondylar eminence fracture among suture anchor,hollow screw and wire was similar. By contrast,the fixation of fracture by use of suture anchor can decrease operation time and hospital stay to some extent. It had advantage of need not to have a second operation to remove the internal fixation and can be used in preference.
ABSTRACT
Objective @#To investigate possible functional disorders of central auditory processing and language in school-age children with cleft palate through an assessment of the characteristics of the P300 and N400 event-related potentials (ERPs). @*Methods @# This study included 28 school-age children with cleft palate, aged 6 to 12 years, and 30 children without cleft palate as a control group. The P300 and N400 ERPs were selected as indexes of the central auditory processing and language functions of children in both groups. The data were statistically compared between the two groups.@*Results @#Compared with the controls, the children with cleft palate showed a significantly prolonged P300 latency (331.73 ± 14.94 ms vs. 348.64 ± 14.66 ms, P < 0.05) and a significantly decreased P300 amplitude (13.47 ± 2.24 μV vs. 12.07 ± 2.46 μV, P < 0.05). Similarly, the N400 latency of children with cleft palate was significantly prolonged compared to that of controls (431.07 ± 17.90 ms vs. 408.23 ± 18.04 ms, P < 0.05), and the N400 amplitude was significantly decreased compared to that of controls (13.75 ± 2.12 μV vs. 15.17 ± 2.34 μV, P < 0.05). @* Conclusion@#School-age children with cleft palate may have central auditory processing disorders and language dysfunctions.
ABSTRACT
Objective To analyze the possibilities of screening SPF rabbits and guinea pigs from conventional animals, viral antibodies of the conventional rabbits and guinea pigs bred by licensed companies in Guangdong province during 2014-2016 were determined according to the standard of SPF animals in GB14922. 2. Methods Nine batches of 167 rabbit sera and 155 guinea pig sera were sampled from 6 companies. Serum antibodies to virus were determined by ELISA according to GB14922. 2. Results Positivity of antibody to rabbit hemorrhagic disease virus (RHDV) was 82. 2%(129/157) for the vaccinated rabbits, and negative result were obtained for unvaccinated rabbits. Positive rate of rabbit rotavirus (RRV) was 42. 5% (71/167). No positive antibody responses to Sendai virus were detected out in all rabbits. The positive rates of guinea pig reovirus type III (REO-3) and pneumonia virus of mice (PVM) were 52. 9%(82/155)and 20% (31/155) respectively. Antibody responses to Sendai virus ( SV) and lymphocytic choriomeningitis virus ( LCMV) were negative in all guinea pigs. Conclusions Although the conventional rabbits and guinea pigs could meet the national standard, higher infection rates of virus excluded that SPF animals emerged in conventional animals, indicating that selection of SPF animals from conventional colonies is impracticable.
ABSTRACT
Objective To conduct a microbiological and parasitological investigation of experimental minipigs in Guangdong province. Methods Four major experimental minipig production units in Guangdong province were included in this investigation. Samples were taken from a total of 154 pigs of 4 brreds, i. e. , Bama minipigs, Juema minipigs, Tibet minipigs and Wuzhishan minipigs. Pig fur, scales, serum, rectal swabs and feces samples were collected for detection of 20 pathogens. The data were analyzed and compared among the production units and breeds. Results Mixed infections were detected in all the four institutions. The infection rates of 7 pathogens were rather high: Streptococcus suis type 2 (50. 7%), Actinobacillus pleuropneumoniae (40. 3%), Mycoplasma hyopneumoniae (100%), Japanese encephalitis virus (41. 3%), porcine circovirus type 2 (74. 8%), porcine transmissible gastroenteritis virus (73. 8%),gastroenteritis virus (44. 7%). Porcine parvovirus (26. 0%), pseudorabies virus(15. 6%) and intestinal worms (3. 2%) were also detected in some animals. The immune qualified rates of classical swine fever virus (62. 8%) and foot-and-mouth disease virus (35. 8%) were rather low. The immune qualified rate of pseudorabies virus was as high as 98. 4%. Besides, Salmonella, Brucella, swine dysentery snake like spirochetes, dermatophytes, influenza virus. Toxoplasma gondii, ectoparasites, and coccidia were not detected. Conclusions The results of this investigation indicate that epidemiological quality control of pathogens in experimental minipigs and efforts to establish high grade minipig population in Guangdong province remain to be strengthened. Our study also provides a basis for revision of local and even national standards for experimental minipigs.

Methods One hundred and forty-eight patients with the anterior cruciate ligament injury received surgical treatment were enrolled from January 2011 to January 2015 and divided into two groups,including group M(Men)and group W(Women). Patients in each group were also divided in the allograft group (Group A) and the autologous hamstring tendon group (Group B). The patient condition was separately assessed with the Lysholm,Tegner,VAS score and the value of KT-1000 before and after surgery. Results All patients received an average of 16(13-18)-month follow-up visit. No severe complication , such as blood-vessel and nerve injury ,infection and rupture of graft ,occurred in patients after operations. Compared with those before operation,the Lysholm,Tegner,VAS score and the value of KT-1000 after operation in four groups were significantly improved (P 0.05). Conclusions The curative effect of ACL reconstruction between allograft ligament and autologous hamstring tendon has no significant difference in gender. The selection of graft should be considered in more aspects.
ABSTRACT
Objective To compare and analyze the curative effects of mediopatellar plica syndrome under different therapies. Methods 147 patients with mediopatellar plica syndrome were enrolled in the study from January 2011 to January 2015 and divided into three groups refer to treatment: Group A, B and C. Each group was also divided in the youth group and the mid-age group. Different treatments were used in the three groups. Group A: drug therapy and physicotherapeutics; Group B: intraarticular injection regularly; Group C: arthroscopic surgical treatment. All patient conditions were assessed with Lysholm score. Results All patients received an average of 11 (9 ~ 13) months follow-up. No blood-vessel and nerve injured and infection occurred. Before receiving treatment, difference in Lysholm score of the three groups showed no statistical difference (F = 0.08, P = 0.926); after treatment, difference revealed significant difference (F = 15.48, P = 0.001). Compared with those before operation and after operation among the three groups, the Lysholm score was improved (tA = 3.43, tB = 6.74, tC = 7.99, P = 0.001). In the rangeability of Lysholm score, the Group C > B > A (F = 66.43, tAB = 5.97, tAC = 11.52, tBC = 5.55, P = 0.001);The general youth group > the general mid-age (t = 7.91, P = 0.001). Conclusion The best therapeutic method for mediopatellar plica syndrome is the arthroscopy. As for mid-age patients, it is necessary to inform them of possibility that prognosis is not well in preoperative planning.
