ABSTRACT
Objective To analyze the influencing factors of peritoneal dialysis associated peritonitis(PDAP)and the distribution characteristics of pathogenic bacteria.Methods The clinical data of 257 patients who underwent peritoneal dialysis(PD)and regular follow-up in Meizhou People's Hospital from January 2012 to October 2022 were retrospectively analyzed.According to the occurrence of PDAP,the patients were divided into the PDAP group(n=102)and the non-PDAP group(n=155).The exhaled liquid(5-10 mL)was extracted with a sterile syringe,and the pathogen was identified by blood culture method.General data such as gender,age,primary disease,education level,whether complicated with hypertension/diabetes/cardiovascular diseases,whether keeping pets or poultry,body mass index(BMI)and dialysis duration were collected.Fasting elbow venous blood was drawn in the morning of the next day after diagnosis,the levels of hemoglobin(Hb),albumin(ALB),serum potassium,serum phosphorus,and serum calcium were detected.The estimated glomerular filtration rate(eGFR)and urea clearance index(UCI)were recorded.Multivariate logistic regression was used to analyze the risk factors of PDAP in PD patients.Results There were 217 cases of PDAP in 102 patients with PDAP,and 124 cases(57.14%)were positive for pathogen culture.A total of 127 pathogenic bacteria were isolated,including 84 Gram-positive strains(66.14%),39 Gram-negative strains(30.71%)and 4 Fungi strains(3.15%).Among the 84 strains of Gram-positive bacteria,there were 25 strains of staphylococcus epidermidis(29.76%),17 strains of staphylococcus aureus(20.24%),12 strains of staphylo-coccus haemolyticus(14.29%),8 strains of staphylococcus warneri(9.52%),10 strains of streptococcus salivarius(11.90%),5 strains of streptococcus sanguis(5.95%),and 7 other strains(8.33%).Among the 39 strains of Gram-nega-tive bacteria,there were 20 strains of escherichia coli(51.28%),6 strains of pseudomonas aeruginosa(15.38%),6 strains of acinetobacter baumannii(15.38%),5 strains of klebsiella pneumoniae(12.82%),and 2 strains of enterobacter cloacae(5.13%).Among the 4 strains of Fungi,there were 3 strains of near-smooth candida(75.00%)and 1 strain of candida glabrata(25.00%).There was no significant difference in gender,age,primary disease,education level,BMI,and the propor-tion of comorbidities with hypertension,diabetes and cardiovascular diseases between the PDAP and non-PDAP groups(P>0.05).The proportion of patients keeping pets or poultry in the PDAP group was higher than that in the non-PDAP group,and the dialysis duration was longer than that in the non-PDAP group(P<0.05).There was no significant difference in serum phosphorus,serum calcium,eGFR and UCI between the PDAP and non-PDAP groups(P>0.05).The levels of Hb,ALB and serum potassium in the PDAP group were significantly lower than those in the non-PDAP group(P<0.05).Logistic regression analysis showed that keeping pets or poultry and long dialysis duration were risk factors for PDAP in PD patients(P<0.05).High Hb and ALB levels were protective factors for PDAP in PD patients(P<0.05).There was no correlation between serum potassium and PDAP in PD patients(P>0.05).Conclusion Gram-positive bacteria are the main pathogenic bacteria of PDAP,among which staphylococcus epidermidis is the predominant one.Keeping pets or poultry and long dialysis duration are risk factors for PDAP,while high Hb and ALB levels are protective factors for PDAP in PD patients.
ABSTRACT
Objective:To study the clinical efficacy of modified open elbow arthrolysis in the treatment of traumatic elbow stiffness.Methods:A retrospective analysis was performed on 120 patients who underwent modified open elbow arthrolysis in Beijing Jishuitan Hospital from January 2018 to December 2020. The age of the included patients was (37.7±12.4) years (ranged 18-64 years), including 54 males and 66 females. The medical records were reviewed, the range of motion (ROM) and functional status of the patients before operation and at the last follow-up were compared including visual analogue scale (VAS), Mayo elbow performance score (MEPS), Disabilities of the arm, shoulder and hand (DASH) score. Complications and secondary operations were also recorded. Measurement data with normal distribution were presented as mean ± standard deviation( ± s) and comparison between groups was conducted using the t-test; Measurement data of skewed distribution were expressed as M ( Q1, Q3), and Rank-sum test was used for inter-group comparison. Results:The preoperative extension of 120 patients was 43.6° (33.8°, 60.1°), the flexion was 78.7° (59.8°, 98.1°), and the flexion-extension ROM was 25.6° (0.0°, 54.5°); the preoperative pronation was 51.8° (33.0°, 67.0°), the supination was 85.1° (65.7°, 90.0°), and the rotation ROM was 136.9° (99.1°, 157.5°). Postoperative extension was 14.2° (7.0°, 24.8°), flexion was 129.5° (120.0°, 138.1°), flexion-extension ROM was 115.5° (94.4°, 127.3°); postoperative pronation was 65.0° (47.1°, 75.0°), the supination was 88.3° (78.6°, 90.0°), and the rotation ROM was 151.9° (131.7°, 163.4°). Postoperative extension, flexion, flexion-extension ROM, pronation, supination, and rotation ROM were all higher than those before operation, and the differences were statistically significant ( P<0.001). The VAS of 120 patients was 1.0 (0.0, 3.0) scores before operation and 0.0 (0.0, 1.0) scores after operation. The MEPS was 60.0 (50.0, 75.0) scores before operation and 100.0 (85.0, 100.0) scores after operation. The preoperative DASH was 37.5 (20.1, 51.3) scores, and the postoperative DASH was 7.9 (3.3, 13.3) scores. The postoperative VAS, MEPS, and DASH were significantly improved compared with those before operation, and the differences were statistically significant ( P<0.001). Residual ulnar nerve symptoms occurred in 18 cases, recurrence of heterotopic ossification in 42 cases, and hematoma in 3 cases. Conclusions:Modified open elbow arthrolysis is a safe and effective surgical method for the treatment of traumatic elbow stiffness. It can significantly improve the function of the patient, reduce the occurrence of elbow instability, avoid the use of external fixators, and reduce the cost of the patient.
ABSTRACT
Objective:To explore the association between the frequency of using smoking cessation application (APP) and the effect of smoking cessation in smoking cessation clinic.Methods:A clinical trial with a non-randomized controlled design was conducted in the smoking cessation clinic of China-Japan Friendship Hospital from July 2019 to June 2021. Participants were given a comprehensive smoking cessation intervention of mobile APP combined with bupropion. The primary outcome measures were carbon monoxide validated sustained abstinence at 9-12 weeks.Results:A total of 187 participants were included in the final analysis. After 12-week intervention, the sustained abstinence at 9-12 weeks was 42.2%. For the frequency of APP use, 20.9% (39/187) of the participants used it≥6 days per week, 62.0% (116/187) used it 2-5 days per week, and 17.1% (32/187) used it≤1 day per week. Multivariate analysis showed that smoking cessation rate was associated with smoking duration, cigarettes smoked per day and frequency of APP use. Participants with higher frequency of APP use had a higher likelihood of quitting smoking ( OR=4.95, 95% CI: 1.32-18.63). Conclusion:The increased frequency of mobile smoking cessation APP use is associated with higher probability of quitting smoking in smoking cessation clinic.

ABSTRACT
Objective:To investigate the efficacy of TiRobot navigation for hinged external fixation in elbow arthrolysis.Methods:The 11 patients were retrospectively analyzed who had been treated by elbow arthrolysis at Department of Traumatology and Orthopedics, Beijing Jishuitan Hospital using TiRobot navigation for hinged external fixation. There were 9 males and 2 females with a mean age of 39.3 years (from 21 to 66 years). Their elbow range of motion (ROM) was compared between preoperation and the final follow-up. Their visual analogue scale (VAS) and Mayo elbow performance score (MEPS) and complications were documented at the final follow-up.Results:The rotation axis of the elbow joint was positioned with the aid of intraoperative robot navigation in 11 patients.The deviation of entry point averaged 0.21 mm (from 0.05 to 0.41 mm) and the deviation of exit point 0.23 mm (from 0.06 to 0.38 mm). The follow-up time for the 11 patients averaged 25.8 months (from 16 to 32 months). Their elbow flexion and extension was 133.0° (134.9°, 138.7°) and rotation 164.6° ±17.5° at the final follow-up, significantly improved compared with their preoperative values [0.8°(0°, 33.7°) and 122.9°±49.0°] ( P<0.05). Their VAS averaged 0.2 (from 0 to 1) and MEPS 96.8 (from 85 to 100) at the final follow-up, giving 9 excellent and 2 good cases. There was no case of radial nerve injury, pin instability, pin breakage, pin infection or peri-pin fracture. Conclusion:When TiRobot navigation is used for hinged external fixation in elbow arthrolysis, the axis of rotation can be accurately located, leading to satisfactory functional outcomes for the patients.
ABSTRACT
Objective:To observe the effects of esketamine combined with butorphanol in endotracheal intubation guided by fiberoptic bronchoscopy with spontaneous breathing.Methods:Forty patients suspected of having difficult airways during elective general anesthesia operations in Hunan Provincial People′s Hospital were prospectively selected and divided into control group and observation group by random number table. Propofol plus sufentanil, esketamine plus butorphanol were used for intravenous general anesthesia respectively. At the same time, they were assisted with cricothyroid puncture and surface anesthesia of nasopharynx and larynx, and then trachea intubation with spontaneous breathing was performed through the nose under the guidance of fiberoptic bronchoscope. The changes of heart rate (HR), mean arterial pressure (MAP), arterial partial pressure of oxygen (PaO 2), and the levels of serum cortisol, norepinephrine and adrenaline before and after endotracheal intubation were compared between the two groups. The number of body motions and coughing at the completion of endotracheal intubation was compared between the two groups. Results:In the control group, the HR and MAP at the completion of intubation were higher than those before intubation, and the PaO 2 was lower than those before intubation (all P<0.05); In the observation group, there was no significant difference in HR, MAP and PaO 2 at the completion of intubation and before intubation (all P>0.05). The HR and MAP at the end of intubation in the observation group were lower than those in the control group, and the PaO 2 was higher than that in the control group (all P<0.05). The number of body motion and coughing in the observation group was significantly less than that in the control group at the completion of endotracheal intubation (all P<0.01). At the end of endotracheal intubation, the serum cortisol, norepinephrine and epinephrine level in the observation group were significantly lower than those in the control group (all P<0.01). Conclusions:Esketamine combined with butorphanol has advantages over propofol combined with sufentanil in the application of fiberoptic bronchoscopy guided tracheal intubation in difficult airways that retain spontaneous breathing, and can better control the stress response caused by tracheal intubation.
ABSTRACT
Objective:To study the locational distribution characteristics of the heterotopic ossification (HO) following traumatic elbow stiffness and the risk factors for HO development at different locations.Methods:Consecutively included according to our inclusion criteria in the present study were the patients who had been admitted to Department of Orthopaedic Trauma, Beijing Jishuitan Hospital from January 2018 to December 2018 for elbow release due to traumatic elbow stiffness but developed postoperative HO. Their baseline data and CT data were collected and processed using Mimics 20.0. The HO distribution for each patient was characterized at the anteromedial, anterolateral, posteromedial, posterolateral, posterior, medial, lateral, and proximal radioulnar locations. The patient's original injury was categorized into 5 types: distal humerus fracture, olecranon fracture, radial head fracture, coronoid fracture, and elbow dislocation. After the univariate analysis with the HO occurrence at a specific location as the dependent variable and the original injury and baseline data as the independent variables, the factors with P value less than 0.1 were included in the logistic regression analysis to determine the risk factors for HO at each location.Results:A total of 91 patients were included in this study. Of them, 88 had posteromedial HO (96.7%, 88/91), 62 posterior HO (68.1%, 62/91), 60 posterolateral HO (65.9%, 60/91), 41 anteromedial HO (45.1%, 41/91), 26 anterolateral HO (28.6%, 26/91), 13 proximal radioulnar HO (14.3%, 13/91), 8 lateral HO (8.8%, 8/91), and 7 medial HO (7.7%, 7/91). Logistic regression analysis showed that presence of ulnar nerve symptoms ( OR=4.354, P=0.017) and presence of original elbow dislocation ( OR=2.927, P=0.042) were the independent risk factors for the anteromedial HO development and that presence of original olecranon fracture ( OR=0.277, P=0.023) was the protective factor for the anteromedial HO development. Presence of original radial head fracture was the independent risk factor for the anterolateral HO development ( OR=2.891, P=0.033) and the posterolateral HO development ( OR=3.123, P=0.043). Conclusions:HO development in patients with post-traumatic elbow stiffness is closely related to their original injury. Posteromedial HO may develop in almost all the patients. Patients with ulnar nerve symptoms and original elbow dislocation are more prone to anteromedial HO development, but patients with original olecranon fracture are less likely to develop anteromedial HO. Patients with original radial head fracture are more likely to develop anterolateral and posterolateral HO.

ABSTRACT
Objective:To compare the clinical outcomes between OTA/AO-C open and closed fractures of the distal humerus treated by open reduction and internal fixation.Methods:The clinical data were retrospectively analyzed of the 70 patients who had been treated at Department of Traumatology and Orthopedics, Beijing Jishuitan Hospital for OTA/AO-C fractures of the distal humerus from January 2014 to June 2017. Of them, 22 suffered from open fractures (Gustilo types Ⅰ/Ⅱ) and 48 closed fractures. There were 18 males and 4 females with an age of (42.6±13.0) years in the open group and 21 males and 27 females with an age of (42.2±17.1) years in the closed group. Analyzed were interval from injury to surgery, hospitalization time, injury energy and functional outcomes which included range of motion (ROM) in elbow flexion and extension, ROM in elbow rotation, Mayo elbow performance score (MEPS), Disabilities of the Arm, Shoulder and Hand (DASH), complications and rate of secondary surgery.Results:There was no significant difference between the 2 groups in age, injury energy or interval from injury to surgery ( P>0.05), but there were significantly more males in the open group than in the closed group ( P=0.011). The follow-up time for all the patients averaged 34.0 months (from 25 to 54 months). There were no statistically significant differences between the 2 groups in hospitalization time [9.5(6.0, 13.0) d versus 8.5 (6.0, 11.0) d], ROM in flexion and extension [120.0° (100.0°, 137.8°) versus 128.5° (110.0°, 140.0°)], ROM in rotation [155.0° (151.3°, 155.0°) versus 155.0° (155.0°, 155.0°)], MEPS [95.0 (80.0, 100.0) versus 95.0 (80.0, 100.0)] or DASH [2.6 (0.63, 9.2) versus 1.7 (0.0, 8.5)] ( P>0.05). There were no statistically significant differences between the 2 groups either in rate of secondary surgery [36.4% (8/22) versus 33.3% (16/48)], ulnar nerve symptoms [54.5% (12/22) versus 60.4% (29/48)], local irritability in the region of internal fixation [9.1% (2/22) versus 6.3% (3/48)] or elbow stiffness [13.6% (3/22) versus 10.4% (5/48)] ( P>0.05). Conclusion:Open reduction and internal fixation can lead to similar clinical outcomes in the treatment of both open (Gustilo types Ⅰ/Ⅱ) and closed distal humeral fractures of OTA/AO-C, with no significant differences in postoperative ROM, functional scores or complications.
ABSTRACT
Objective:To explore the effect of combined administration of intravenous and topical tranexamic acid on perioperative blood loss in elbow arthrolysis.Methods:A retrospective analysis was conducted of 31 patients who had undergone elbow arthrolysis due to elbow stiffness from April 2019 to November 2020 at Department of Orthopaedic Trauma, Beijing Jishuitan Hospital. An observational group of 15 patients were subjected to combined administration of intravenous and topical tranexamic acid while a control group of 16 patients to no administration of tranexamic acid. In the observational group, 15 mg/kg of tranexamic acid was injected intravenously 5 to 10 minutes before surgery and 1.0 g of tranexamic acid was injected locally in the area of anterior and posterior joint capsules after incision was closed while drainage tubes were clamped for 2 hours before release. In the control group, there was no special operative procedure while drainage tubes were also clamped for 2 hours before release. The 2 groups were compared in terms of blood loss on day 1 and day 3 after operation, drainage volume on day 1 after operation, total drainage volume, time for indwelling drainage tube, complications, and Mayo elbow performance score (MEPS) at 3 months after operation.Results:There were no statistically significant difference in preoperative general data between the 2 groups, showing they were comparable ( P>0.05).On day 1 and day 3 after operation, the blood loss was respectively (533.4±318.3) mL and (792.0±375.6) mL in the observational group, and respectively (866.4±480.5) mL and (1,403.0±636.5) mL in the control group, showing significantly differences between the 2 groups ( P<0.05). The drainage volume on day 1 after operation was (151.3±90.1) mL in the observational group and (235.0±126.1) mL in the control group, showing a significant difference between the 2 groups ( P<0.05). There was no statistically significant difference in total drainage volume or time for indwelling drainage tube between the 2 groups ( P>0.05). There were no such complications as thromboembolic events in either group. There was no significant difference in MEPS between the 2 groups at 3 months after operation ( P>0.05). Conclusions:Combined administration of intravenous 15 mg/kg and topical 1.0 g tranexamic acid may reduce blood loss on day 1 and day 3 after operation and drainage volume on day 1 after operation, and may not increase the risk of thromboembolic events, but cannot reduce total drainage volume or time for indwelling drainage tube. Application of tranexamic acid may not affect early elbow joint function after operation.
ABSTRACT
Excess activation of cardiac fibroblasts inevitably induces cardiac fibrosis. Emodin has been used as a natural medicine against several chronic diseases. The objective of this study is to determine the effects of emodin on cardiac fibrosis and the underlying molecular mechanisms. Intragastric administration of emodin markedly decreased left ventricular wall thickness in a mouse model of pathological cardiac hypertrophy with excess fibrosis induced by transaortic constriction (TAC) and suppressed activation of cardiac fibroblasts induced by angiotensin II (AngII). Emodin upregulated expression of metastasis associated protein 3 (MTA3) and restored the MTA3 expression in the setting of cardiac fibrosis. Moreover, overexpression of MTA3 promoted cardiac fibrosis; in contrast, silence of MTA3 abrogated the inhibitory effect of emodin on fibroblast activation. Our findings unraveled the potential of emodin to alleviate cardiac fibrosis upregulating MTA3 and highlight the regulatory role of MTA3 in the development of cardiac fibrosis.

ABSTRACT
MicroRNA (miRNA) is a kind of non-coding small RNAs,which can regulate target mRNA at post-transcriptional level and play an important regulatory role in a variety of biological processes in epigenetics field.Myopia is a complex disease caused by both genetic and environmental factors.Recently,epigenetic regulation has been found to be closely related to pathogenesis of myopia,in which miRNA play an important role.This article briefly introduced structure and function of miRNAs,differential expression of miRNA in ocular tissues (retina and sclera) and miRNA regulation of myopia-related genes,such as paired box 6 (PAX6),type Ⅰ collagen α1 chain (COL1A1) and matrix metalloproteinase 2 (MMP2).The progress of miRNAs research was reviewed.
ABSTRACT
This article provides an overview of the severe acute respiratory syndrome (SARS) epidemics in mainland China and of what we have learned since the outbreak.The epidemics spanned a large geographical extent but clustered in two regions:first in Guangdong Province,and about 3 months later in Beijing and its surrounding areas.The resulting case fatality ratio of 6.4% was less than half of that in other SARS-affected countries and regions,partly due to younger-aged patients and a higher proportion of community-acquired infections.Strong political commitment and a centrally coordinated response were most important for controlling SARS.The long-term economic consequence of the epidemic was limited.Many recovered patients suffered from avascular osteonecrosis,as a consequence of corticosteroid usage during their infection.The SARS epidemic provided valuable experience and lessons relevant in controlling outbreaks of emerging infectious diseases,and has led to fundamental reforms of the Chinese health system.Additionally,the epidemic has substantially improved infrastructures,surveillance systems,and capacity to response to health emergencies.In particular,a comprehensive nationwide internet-based disease reporting system was established.

ABSTRACT
<p><b>Background</b>Several studies have investigated the association between smoking and anal abscess and anal fistula (AA/F) diseases. However, the relationship between cigarette smoking and AA/F remains unclear. This study sought to assess the role of smoking in anorectal male patients in a Chinese population.</p><p><b>Methods</b>In this retrospective study, a questionnaire, including smoking history, was completed over a 3-month period by male inpatients in the Proctology Department of China-Japan Friendship Hospital. "Cases" were patients who had AA/F, and "controls" were patients with other anorectal complaints. Mann-Whitney U-test and Chi-square test were carried out to examine differences in baseline characteristics between groups. Subsequently, multivariate logistic regression was used to explore any related factors.</p><p><b>Results</b>A total of 977 patients aged from 18 to 80 years were included, excluding those diagnosed with inflammatory bowel disease or diabetes mellitus. Out of this total, 805 patients (82.4%) completed the entire questionnaire. Among the 805 patients, 334 (41.5%) were cases and 471 (58.5%) were controls. Results showed significant differences between cases and controls (χ = 205.2, P < 0.001), with smoking found to be associated with the development of AA/F diseases (odds ratio: 12.331, 95% confidence interval: 8.364-18.179, P < 0.001).</p><p><b>Conclusions</b>This study suggested smoking to be a potential risk factor for the development of AA/F diseases in a Chinese population. Consequently, current smoking patients should be informed of this relationship, and further research should be conducted to explore and investigate this further.</p>

OBJECTIVE@#To investigate the effect of interleukin -8 (IL-8) on immune function in acute lymphoblastic leukemia patients and its related mechanisms.@*METHODS@#Forty-five ALL patients were selected from January 2014 to September 2017 in our hospital. Out of them, 32 relieved patients were included in group A, 13 patients did not relieved patients after treatment and were included in the group B. The serum IL-8 level was detected by ELISA.Th1 and Th2 cells were measured by flow cytometry. After Th cells were treated with different concentration of IL-8, the Western blot was used to detect the translation levels of p-STAT3 and JAK in cells.@*RESULTS@#The difference of white blood cell count and clinical risk level between the 2 groups was statistically significant (P0.05).@*CONCLUSION@#IL-8 can interfere the balance of Th1/Th2 through STAT3 signaling pathway, and has effect on the immune function of ALL patients.

To explore the role of vascular endothelial growth factor (VEGF) in diabetic peripheral neuropathic pain in rats. Methods: Twenty-four adult male Sprague-Dawley rats aged 8 weeks were randomly divided into 3 groups (n=8 per group). The control group (C group): rats were intraperitoneally injected with sodium citrate solution at 10 mL/kg; the model group (M group): rats were intraperitoneally injected with streptozotocin at 65 mg/kg; the treatment group (T group): rats received intraperitoneal injection of anti-VEGF antibody (10 mg/kg) at the 1st, 3rd, 7th, 10th day after STZ treatment. Meanwhile, rats of C and M group were received with the same volume of sodium citrate solution. Blood glucose was measured before 1 day or at the 1st, 3rd, 7th or 14th day after receiving STZ. Body weight, paw withdrawal mechanical threshold (PWMT) and paw withdrawal thermal latency (PWTL) were measured before 1 day or at the 1st, 3rd, 5th, 7th, 10th or 14th day after receiving STZ. All lumbar spinal cords were dissected to examine the p-protein kinase B (p-Akt) and transient receptor potential vanilloid 1 (TRPV1) expression by Western blot. Results: After injection with STZ, the body weight showed significant differences at some time point between the M, T or C group (P<0.01); body weight of rat in the C group were increased gradually. Compared with the C group, the fast blood glucose in the M or the T Group at the same time points were increased significantly (P<0.01). The PWMT and PWTL of the M, T or C group were significant difference among various time points (P<0.01). The PWMT and PWTL in the M or T group were obviously reduced compared with those in the C group (P<0.01). Compared with the M group, the PWMT and PWTL in the T group were increased at the 10th or 14th day (P<0.01 or P<0.05). Compared with the C group, the p-Akt and TRPV1 levels in the M and T group were increased (P<0.01). Compared with the M group, p-Akt and TRPV1 levels in T group were decreased (P<0.01). Conclusion: VEGF is able to regulate the expression of TRPV1 through PI3K/Akt pathway, which contributes to diabetic peripheral neuropathic pain in rats. Anti-VEGF treatment may be useful for alleviation of diabetic peripheral neuropathic pain.

Objective To observe the clinical efficacy of modified laminoplasty with C3 laminectomy and C7 spinous process retention in the treatment of cervical ossification of the posterior longitudinal ligament(OPLL).Methods From February 2014 to March 2016,133 cases of OPLL were admitted,and 42 OPLLs were included according to the inclusion and exclusion criteria.A case-control study was conducted.Twenty-two cases were included in modified group and 20 cases in traditional group.There were 13 males and 9 females in the modified surgery group,and the average age was 56.2±9.75 years (39-77 years).Modified surgery was conducted with C3 laminectomy,C4-C6 laminoplasty,resection at the upper part of the C7 lamina and retaining the C7 spinous process.Meanwhile,there were 12 males and 8 females in the traditional surgery group,with an average age of 53.7± 8.23 years (41-75 years).Patients in the traditional surgery group were treated with standard C3-C7 laminoplasty.The mean followup was 22.9±4.5 (15-29) months.The JOA,NDI scores of the two groups were recorded preoperatively and postoperatively.The physiological curvature and activity of the cervical spine before and after operation were observed,and the incidence of axonal symptoms and postoperative complications in both groups were recorded.Results The follow-up period was 15-28 months,with an average of (23.2 ± 4.8) months.There was no significant difference between the base line of two groups before operation.At the last follow-up,the JOA and NDI scores of the two groups were significantly improved.There was no difference of JOA scores between the two groups at the last follow-up,while the NDI sores at the modified group(6.56±4.78) was superior to the traditional group(9.25±7.63).The VAS score at the first day after surgery in modified group was lower than that of the traditional group.The average cervical curvature of the patients in the modified surgery group and the standard surgery group were 12.32°±8.26° and 11.56°± 8.05°,respectively.There was no significant difference between the two groups.The postoperative range of movement (ROM) of cervical spine was 39.68°±9.52° in modified group and 33.51°± 10.39° in traditional group(P<0.05).Eight patients (19%) had augmentation of axial symptoms,including 3 patients in the modified surgery group(13.6%) and 5 patients in the standard surgery group (30%).There was no significant difference between the two groups.During the follow-up period,there were no complications such as cerebrospinal fluid leakage,spinal cord injury,wound infection,laminar collapse,postoperative closure,internal fixation loss or fracture.Conclusion The modified laminectomy with C3 laminectomy and C7 spinous process retentionis minimally invasive,whichachieved satisfactory decompression effect,reduced the incidence of postoperative axial symptoms and maintained the cervical ROM.
ABSTRACT
Health Human Resource Development Cooperation(HHRDC) is a critical component in Chinese foreign aid,which had cultivated thousands of health workers for Asian and Arican developing countries by on-job training,degree education,short-term exchange activities for more than 60 years.This paper systematically reviewed the management mechanism,mode and features of HHRDC via literature review,stakeholders interviews and field investigations,and it is found that the main mode of HHRDC is short-term on-job training,but its effect for capacity building is limited;although degree education account for a small proportion of HHRDC,it plays an important role for elite cultivation;the impact for medical team teaching and technical cooperation have become more obvious;the "going out" training have less invest,short period,but bigger social impact.The main challenges of HHRDC includes the deficiency of specific strategies and action plans;the lack of understanding on recipient countries' health human resource situation,characteristics and needs;the alignment with other aid programs;the lack of timely evalu ation towards current cooperation projects.According to the need analysis of undeveloped countries,it is suggested that a cooperation plan for HHDRC is required;the implementation of HHRDC should integrate into other aid programs;the follow-up mechanism and evaluation system need improved;the Chinese degree certification and qualification in local institutions need promoted;the aid to medical educational institutions should added,thereby strengthening developing countries' capacity and realizing common development.
