ABSTRACT

As the research of traditional Chinese medicine (TCM) on knee osteoarthritis (KOA) is progressing, researchers have discovered that a variety of Chinese medicines can delay the progress of KOA by regulating signaling pathways at the molecular level. The Chinese medicines and their active ingredients mentioned in this article are associated with the signaling pathways in KOA. They can regulate the levels of targeted molecules via different signaling pathways to inhibit cartilage inflammatory cytokine, apoptosis, and cartilage matrix degradation and promote chondrocyte autophagy, so as to reduce the synovial inflammatory edema and delay cartilage degeneration. This paper systematically reviews the studies about the TCM intervention of KOA. Baicalein can reduce the inflammatory cytokines and apoptosis and promote the autophagy of chondrocytes by blocking the phosphatidylinositol-3 kinase/protein kinase (PI3K/Akt) signaling pathway. Cornuside I can decrease the phosphorylation activity of Janus kinase 2/signal transducer and activator of transcription 3 (JAK2/STAT3) pathway to reduce synovial inflammation and delay cartilage matrix degeneration. Salvianolic acid A can reduce inflammation and cartilage matrix degradation by inhibiting the phosphorylation of the nuclear factor-κB (NF-κB) pathway. Emodin can reduce the activity of Wnt/β-catenin pathway to inhibit the decomposition of collagen and proteoglycan. Myristicoside can inhibit apoptosis by blocking the p38 mitogen-activated protein kinase (p38 MAPK) signaling pathway. Akebia saponin D can enhance the activity of nuclear factor E2-related factor 2/heme oxygenase 1(Nrf2/HO-1) pathway to inhibit oxidative stress in chondrocytes. The saponins in Achyranthis Bidentatae Radix reduce cartilage matrix degradation by enhancing the transforming growth factor-β (TGF-β)/Smad signaling pathway. Crocin inhibits the cartilage inflammation and apoptosis factor increase by stimulating the activity of hippo-Yes-associated protein (Hippo-YAP). Ligustrazine blocks the Notch pathway to improve the morphology and abnormality of chondrocytes. Oleanolic acid reduces the destruction and degeneration of cartilage matrix via the estrogen signaling pathway. The above summary aims to provide references for future clinical and experimental research on KOA.

ABSTRACT

Objective To evaluate the value of PLT and its parameters combined with AFP, CA199, CA125 and CEA on the preoperative differential diagnosis of hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC). Methods We analyzed retrospectively 274 patients with liver cancer who underwent surgery in the Second Hospital of Lanzhou University. They were divided into 229 cases in HCC group and 45 cases in ICC group according to postoperative pathological results. The differences of PLT, its parameters and tumor markers between the two groups were compared. ROC curve was used to evaluate the differential diagnosis effect on HCC and ICC by significantly different indicators in single and combined forms. The best scheme was verified in the patients with determined and undetermined preoperative diagnosis. Results Compared with HCC group, the levels of PLT, PCT, CA199 and CA125 in ICC group were higher (P < 0.05) and the level of AFP was lower (P < 0.05). The diagnostic analysis results of ROC curve showed that in single test, the AUC of AFP for HCC diagnosis was the largest (0.827). The AUC of the combined groups was higher than the single groups of tumor markers; the AUC of the PCT+AFP+CA199+CA125 group was the highest in all combination groups, and AUC was 0.891. The verification of the best combination group showed that the AUC was 0.924 in the preoperative determined diagnosis group and 0.854 in the undetermined diagnosis group. Conclusion Tumor markers in combination with PLT and PCT can increase the preoperative differential diagnosis efficacy of HCC and ICC. The combination of PCT, AFP, CA199 and CA125 before operation is helpful to further determine the diagnosis and plan the operation scheme.

ABSTRACT

Objective:To investigate the effects of lengths of intramedullary nails on the treatment efficacy of osteoporotic unstable intertrochanteric fracture.Methods:Retrospectively analyzed were the data of patients with osteoporotic unstable intertrochanteric fracture who had been admitted to Department of Orthopedics, China-Japan Friendship Hospital from January 2017 to December 2019. According to the lengths of intramedullary nails, the patients were divided into 2 groups. In the short nail group of 135 cases, there were 38 males and 97 females with an age of (82.2 ± 7.7) years and an intramedullary nail with a length of 170 mm was used. In the long nail group of 32 cases, there were 8 males and 24 females with an age of (81.5±7.1) years and an intramedullary nail longer than 300 mm was used. The amount of intraoperative hemoglobin drop value, operation time, Harris hip score at 6 months after surgery, incidence of complications and mortality were compared between the 2 groups.Results:There was no significant difference in the preoperative general data between the 2 groups, indicating comparability between groups ( P>0.05). There were no significant differences between the 2 groups in intraoperative hemoglobin drop value [(19.8±2.2) g/L versus (20.0±2.1) g/L], Harris hip score (72.0±3.0 versus 71.2±3.6), incidence of complications [3.0% (4/135) versus 6.2 (2/32)] or mortality [14.3% (19/135) versus 15.6% (5/32)] ( P>0.05). The long nail group needed significantly longer operation time than the short nail group [(84.6±5.6) min versus (92.0±7.2) min] ( P<0.05). Conclusions:In the treatment of osteoporotic unstable intertrochanteric fracture, short and long intramedullary nails show no significant difference in hemoglobin drop value, functional score, complications or mortality, indicating they can both lead to safe and reliable curative efficacy. However, long nails need longer operation time.

ABSTRACT

Objective To determine the distribution of common bacteria in hospital infections and to provide a basis for the prevention and control of bacterial infection and for rational use of antibiotics in clinical departments. Methods A retrospective analysis was conducted on common bacterial strains isolated from inpatients of a Grade III class A hospital from 2015 to 2019, including sample source and drug sensitivity changes. Results A total of 4,924 strains of Escherichia coli, 2 762 strains of Klebsiella pneumoniae, 1 297 strains of Staphylococcus aureus, 967 strains of Pseudomonas aeruginosa, and 1 585 strains of Acinetobacter baumannii were detected during the past 5 years. The bacteria were detected mainly from sputum. The resistance rate of Escherichia coli to ampicillin was as high as 88%, and the resistance rate to ceftriaxone was 58.22%. The resistance rate of Klebsiella pneumoniae to ampicillin was higher than 97%. The resistance rate of Staphylococcus aureus to penicillin G reached 93%, and the resistance rates to erythromycin and clindamycin were 60% and 70%, respectively. Pseudomonas aeruginosa had a high resistance rate to ampicillin, but a low resistance rate to other types of antibiotics. Acinetobacter baumannii had a high resistance to common antibacterial drugs. Conclusion Escherichia coli and Klebsiella pneumoniae had a high incidence of nosocomial infections. Pseudomonas aeruginosa and Acinetobacter baumannii both showed serious multi-drug resistance. Clinical departments should strengthen the monitoring of drug sensitivity changes of pathogenic bacteria, and manage and use antibiotics purposefully.

ABSTRACT

Objective:To explore the incidence and morphology of the posterolateral fracture fragment affecting the fibular notch in posterior pilon fracture.Methods:A retrospective analysis was conducted of the CT and clinical data of the 31 patients with posterior pilon fracture who had been treated at Department of Orthopaedic, China-Japan Friendship Hospital from May 2013 to May 2018. They were 17 men and 14 women, aged from 20 to 68 years (average, 42 years). The injury affected the left side in 13 cases and the right side in 18 ones. The incidence of the posterolateral fracture fragments affecting the fibular notch was counted. The morphologic indexes of the fragments were measured like axial angle of their fracture line, fragment area, fragment height, and sagittal angle of their fracture line.Results:A posterolateral fracture fragment affecting the fibular notch was found in all the 31 posterior pilon fractures, giving an incidence of 100% in the posterior pilon fracture. The fracture line of the fragments tended to be in the coronal plane. The axial angle of the fracture line was 20.25°±9.48°; the ratio of the fragment area to the distal tibial articular area was 15.78%±6.75%; the fragment height was 36.59 mm ± 10.70 mm; the sagittal angle of the fracture line was 18.37°±5.45°.Conclusions:A posterolateral fracture fragment affecting the fibular notch can be found in all the posterior pilon fractures. It does not affect a large articular area and its fracture line is usually located in the coronal plane. These data may help choose appropriate surgical approach and internal fixation.

ABSTRACT

Objective@#To study the effects of altitude exposure and altitude exposure on mental health of Tibetan cadres.@*Methods@#105 cadres in Tibet were selected as the research objects. Among them, 74 cadres in Shannan and Lhasa of Tibet (average altitude 3 680 m), 31 in Shigaze and Ali (above 3 800 m) and 14 in Ali (above 4 300 m) were selected. Using Symptom Checklist 90 (SCL-90), Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS) and Ascension Insomnia Scale (AIS), 105 Tibetan aid cadres were tested by SAS, SDS, AIS and SCL-90 one week after entering Tibet and one week before leaving the plateau. The scores were collected and the mental health and sleep status of Tibetan aid workers were measured.@*Results@#The number of positive items of SCL-90 of 105 Tibetan cadres increased from (13.21±9.05) one week after entering Tibet to (38.35±18.84) one week before leaving Tibet. SAS, SDS and AIS also increased from (25.49±5.19), (26.41±5.15), (5.16±3.54) points one week after entering Tibet to (36.78±7.53), (41.42±9.15), (8.71±4.64) points one week before leaving Tibet. The difference was significant in the last week (Z = 8.420, 8.689, 6.277, P<0.01). The correlation analysis between SCL-90 and SAS, SDS and AIS showed that SCL-90 was positively correlated with SAS, SDS and AIS scores (r = 0.651, 0.616, 0.356, P<0.01). Different altitudes have an effect on the mental health of Tibetan aid cadres. The paranoid item scores of Tibetan aid cadres with altitude>4 300 m in SCL-90 were (1.68 ± 0.50) points, which were higher than those of Tibetan aid cadres with altitude<4 300 m (1.24±0.28) points and (1.40± 0.38) points. The difference was statistically significant (F=5.255, P=0.007); The SDS scores of Tibetan aid cadres with altitude>4 300 m were (46.64 ± 7.24) points, which were higher than those of Tibetan aid cadres with altitude<4 300 m (40.76 ± 8.99) points and (40.58 ± 8.28) points. The difference was statistically significant (F=3.223, P=0.044).@*Conclusion@#Exposure to high altitude affects the mental health of cadres assisting Tibet to varying degrees. The mental health of cadres assisting Tibet deserves attention.

ABSTRACT

Objective To evaluate the diagnostic value of acetic acid spray combined with narrow-band imaging ( NBI) for early gastric cancer and precancerous lesion. Methods A total of 136 gastric cancers and precancerous lesions from 132 patients detected by screening endoscopy from November 2015 to November 2017 in Guangming Chinese Medicine Hospital of Pudong New Area, Shanghai were enrolled in this study, and were divided into NBI group, acetic acid spray group, and acetic acid spray combined with NBI group ( combination group) . The image clarity, microsurface pattern, microvascular pattern, demarcation line, and mucosal whitening time were observed, and value of the 3 methods in diagnosis of early gastric cancer and precancerous lesions was analyzed. Results Image clarity of micro glandular in combination group was significantly better than that in NBI group and acetic acid spray group (χ2=8. 766, P=0. 003;χ2=5. 273, P=0. 022) , and image clarity of microvascular in combination group was significantly better than that in NBI group (χ2=7. 457, P=0. 006) . The overall diagnostic coincidence rate with pathology of combination group, NBI group, and acetic acid spray group was 91. 9%(125/136), 85. 3%(116/136), and 89. 7%(122/136), respectively. The diagnostic sensitivity of irregular or missing microsurface, irregular or missing microvascular, obvious demarcation line, mucosal whitening time <30 s for carcinoma ( including high grade intraepithelial neoplasia, early carcinoma and infiltrating carcinoma ) were 92. 3%, 91. 3%, 92. 3% and 90. 4%, respectively, in the combination group, and the diagnostic specificity of above indicators were 93. 8%, 93. 8%, 96. 9% and 90. 6%, respectively, accuracy were 92. 6%, 91. 9%, 93. 4% and 90. 4%, respectively. For observation of microsurface, the combination group was superior to the NBI group (χ2 =7. 378, P=0. 007) , but there was no significant difference compared with the acetic acid spray group (χ2=0. 427, P=0. 513);the acetic acid spray group was superior to the NBI group (χ2=4. 405, P=0. 036) . For observation of microvascular, the combination group was not significantly better than the NBI group (χ2=2. 398, P=0. 122). For observation of demarcation line, the combination group was not significantly better than the NBI group (χ2=2. 722,P=0. 099) and the acetic acid spray group (χ2=0. 216, P=0. 642). There was no difference between the acetic acid spray group and the NBI group (χ2=1. 433, P=0. 231) in observation of demarcation line. Conclusion Acetic acid spray combined with NBI has a good consistency with pathological results with high diagnostic sensitivity and specificity, and can clearly show microsurface of early gastric cancers and precancerous lesions compared to single NBI.

ABSTRACT

Objective To evaluate the effect of oxycodone on function of GABAA receptors in dor-sal root ganglion ( DRG ) neurons of rats with neuropathic pain ( NP ) . Methods Thirty-six adult male Sprague-Dawley rats, weighing 180-220 g, aged 10 weeks, were allocated into 3 groups ( n=12 each) u-sing a random number table method: sham operation group ( group S ) , group NP and oxycodone group ( group O) . The sciatic nerve was only isolated but not ligated in group S. NP was induced by chronic con-striction injury. The sciatic nerve was exposed and 4 loose ligatures were placed on the sciatic nerve at 1 mm intervals with 4-0 chromic catgut. Oxycodone 15μg∕kg was intraperitoneally injected once a day for 14 con-secutive days from ligating the sciatic nerve to satisfaction in group O. The thermal paw withdrawal latency( TWL) was measured at 1 day before establishing the model ( T0 ) and 3, 5, 7, 10 and 14 days after es-tablishing the model ( T1-5 ) . The rats were sacrificed after measurement of pain threshold at T5 , and DRG neurons were acutely isolated for recording the amplitude of GABAA receptors-activated currents using whole-cell patch-clamp technique. Results Compared with group S, the TWL was significantly shortened at T1-5, and the amplitude of GABAA receptors-activated currents in DRG neurons was decreased in NP and O groups (P<0. 05). Compared with group NP, the TWL was significantly prolonged at T1-5, and the ampli-tude of GABAA receptors-activated currents in DRG neurons was increased in group O ( P<0. 05) . Conclu-sion Oxycodone can enhance the function of GABAA receptors-activated currents in DRG neurons and thus enhance GABAA receptors-mediated presynaptic inhibition, which may be related to the mechanism of oxyc-odone-induced reduction of NP in rats.

ABSTRACT

<p><b>OBJECTIVE</b>To summarize the diagnosis and treatment of iatrogenic colonoscopic perforation (ICP).</p><p><b>METHODS</b>Clinical data, treatment course and outcome of 17 patients who developed ICP following colonoscopic examination or operation at Department of Colorectal Surgery, Changhai Hospital from January 2000 to December 2013 were retrospectively analyzed.</p><p><b>RESULTS</b>During above 13 years, a total of 127 106 patients underwent colonoscopic examination or operation, of whom 17 cases (0.013%) had ICP. There were 8 males and 9 females with an average age of 65.2 (32-85) years. The interval between the onset of ICP and clinically diagnosed ICP was 0 to 6 days after performance. ICP occurred in 8 patients following colonoscopy operations, including simple colonic polyp excision, endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD), while in 9 patients following simple colonoscopy examination. Except for one patient who was immediately diagnosed with ICP through the finding of "yellow adipose tissue visible in the vision field" during operation,7 early cases (41.2%) were diagnosed by abdominal X-ray examination, and 9 later cases were confirmed by abdominal CT examination. The perforation sites included sigmoid colon in 5 cases, caecum in 3 cases, descending colon in 3 cases, descending and sigmoid junction in 2 cases, ileum in 1 case, splenic flexure in 1 case, sigmoid and rectum junction in 1 case, retum in 1 case. One case with ICP following ESD after resection of polyp in caecum was cured successfully with conservative treatment, including fasting, gastrointestinal decompression, fluid infusion, anti-infection and nutritional support. One case with ICP, which was found during colonoscopic operation and the perforation was immediately closed with titanium clip, received conservative treatment, including anti-infection and then was cured. Fifteen patients underwent surgery, including 8 patients with primary intention intestinal perforation repair, 4 patients with primary intention resection of associated intestine and anastomosis, 2 patients with primary intention resection of associated intestine and ostomy, 1 patient with primary intention intestinal perforation repair and ostomy. Postoperative abdominal incision infection occurred in 4 cases, pulmonary infection in 1 case, incision infection with cardiovascular event or urinary tract infection in 1 case each. All the patients were cured and discharged. Average hospital stay was 18.6(3-45) days.</p><p><b>CONCLUSIONS</b>ICP should be diagnosed by physical examination and imaging examination as soon as possible. For perforation during colonoscopic performance, colonoscopic titanium clip can be used for closure. Perforation repair is still the main procedure for ICP. If necessary, partial intestinal resection and anastomosis or ostomy can be selected.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To compare the surgical safety and short-term efficacy of minilaparotomy and laparoscopic approach for curative resection of rectal cancer.</p><p><b>METHODS</b>The retrospective cohort study was adopted. A review of patients scheduled to undergo a curative resection of rectal cancer via minilaparotomy or laparoscopic approach at Department of Colorectal Surgery of Changhai Hospital from June 2016 to May 2017 was carried out. All the patients were confirmed as rectal cancer by postoperative pathology. The following patients were excluded from the study: patients who had acute complete obstruction or perforation; patients underwent Miles or Hartmann procedure; patients who required an elongation of the skin incision in minilaparotomy or a conversion from laparoscopic to open surgery. Finally, 216 patients were enrolled in this study, of whom 143 were performed with minilaparotomy approach (minilaparotomy group) and 73 with laparoscopic approach (laparoscopic group) for curative resection of rectal cancer. For the minilaparotomy technique, a 7 cm longitudinal midline incision was made between the pubic symphysis and umbilicus; a wound retractor was applied to the edge of the wound; lymph node dissection around the inferior mesenteric and artery high ligation of inferior mesenteric artery were performed; by moving the minilaparotomy wound laterally and caudad or cephalad with the S-shaped hook, cautious mobilization of the relevant segment of the bowel loop was performed; bowel anastomosis was achieved by using the double-stapled technique; the gap of the pelvic floor peritoneum and mesentery were routinely closed by the absorbable surgical suture in cases with middle and low position rectal cancer. The surgical safety, the condition of resuming and the morbidity of postoperative complication were compared between the two groups.</p><p><b>RESULTS</b>There were 145 men and 71 women. Age ranged from 26 to 87 years, with of mean age of 61 years. According to the TNM stage grouping, there were 61 patients with stage I(, 62 with stage II(, 85 with stage III(, and 8 with stage IIII( disease, respectively. These two groups did not differ significantly in terms of age, sex, body mass index, site of tumor, TNM stage(all P>0.05). All the patients completed the operation successfully. The median operation time of minilaparotomy group was significantly shorter than that of laparoscopic group [164(80-296) minutes vs. 230(90-665) minutes, Z=4.410, P=0.000]. The intraoperative medical consumable expense [11000(7000-22000) yuan vs. 23000(12000-47000) yuan, Z=11.759, P=0.000] and the total hospitalization expense [44000(22000-146000) yuan vs. 57000(45000-126000) yuan, Z=9.637, P=0.000] were significantly lower in the minilaparotomy group. There were no significant differences between the two groups in terms of operative blood loss, number of harvested lymph nodes, distance of distal resection margin, positive rate of circumferential resection margin (all P>0.05). The rate of postoperative complication in minilaparotomy group was 7.0%(10/143) and in laparoscopic group was 9.6%(7/73) without significant difference (χ=0.449, P=0.503). There were 2 patients in each group who required readmission to the hospital within postoperative 30 days. The cause of readmission was ileus or acute hyponatremia in minilaparotomy group, and ileus or pevic infection in laparoscopic group. One patient died of brain death caused by acute pulmonary embolism during the perioperative period in minilaparotomy group.</p><p><b>CONCLUSIONS</b>The minilaparotomy approach for curative resection of rectal cancer is safe and feasible. As compared with laparoscopic approach, it is advantageous to achieve minimal invasiveness and early recovery, but much cheaper and less time consuming.</p>
