ABSTRACT
BACKGROUND: Despite being used as a program of postoperative rehabilitation, few randomized controlled trials have compared the effectiveness of postoperative exercise based on gait analysis in patients with lumbar spinal stenosis (LSS). OBJECTIVE: To investigate the effectiveness of postoperative exercise based on gait analysis in patients with LSS and to compare it with the effectiveness of conventional exercise. METHODS: This was a double-blind, randomized clinical trial. Sixty-eight participants with LSS were randomly assigned to one of two groups. After receiving a standardized surgical procedure, the observation group received exercises based on 3-D gait analysis, and the control group received empirical physiotherapy containing 4 basic interventions. Both groups took a one-hour session twice daily for 2 weeks. The Oswestry Disability Index (ODI) scale and the Visual Analog Scale (VAS) were measured before and 2 weeks and 6 months after intervention. The gait indicators were measured before and 6 months after intervention. RESULTS: At baseline, there were no significant differences in the ODI, VAS or absolute symmetry index (ASI) of the gait variables between the observation group and the control group. However, at 6 months, pain intensity, walking, standing, social life and summary scores of ODI and VAS of the leg demonstrated significant differences (p< 0.05, respectively) between groups, and the observation group had greater reductions in ASI of stride length, hip flexion, knee flexion and ankle dorsiflexion compared with the control group (p< 0.05, respectively). CONCLUSIONS: The postoperative rehabilitation scheme based on gait analysis resulted in significant short- to medium-term improvements in pain intensity, walking, standing, social life and the summary score of ODI, VAS of leg and symmetry of stride length, hip flexion, knee flexion and ankle dorsiflexion compared with empirical exercise in patients with LSS.

INTRODUCTION: To establish an animal model of delayed intravenous resuscitation following seawater immersion after hemorrhagic shock (HS). METHODS: Adult male SD rats were randomly divided into three groups: group NI (HS with no immersion), group SI (HS with skin immersion), and group VI (HS with visceral immersion). Controlled HS in rats was induced by withdrawing 45% of the calculated total blood volume within 30 min. In SI group, immediately after blood loss, 0.5 cm below the xiphoid process was immersed in artificial seawater, at (23 ± 1) °C, for 30 min. In VI group, the rats were performed by laparotomy and the abdominal organs were immersed in (23 ± 1) °C seawater for 30 min. Two hours after seawater immersion, the extractive blood and lactated Ringer's solution were delivered intravenously. The mean arterial pressure (MAP), lactate, and other biological parameters were investigated in different time points. The survival rate of 24 h after HS was recorded. RESULTS: After seawater immersion following HS, MAP and abdominal viscera blood flow decreased significantly, and the plasma levels of lactate and the organ function parameters were increased than the baseline. The above changes in VI group were more serious than those in SI and NI group, especially in myocardial and small intestine damage. The hypothermia, hypercoagulation, and metabolic acidosis were also observed after seawater immersion; the injury was more severely in VI group than that of SI group. However, the plasma levels of sodium, potassium, chlorine, and calcium in VI group were significantly higher than those before injury and in the other two groups. In the VI group, the level of plasma osmolality in instant, 2 h, and 5 h after immersion was 111%, 109%, and 108% of the SI group, respectively, all P < 0.01. The 24-h survival rate of VI group was 25%, which was significantly lower than that of SI group (50%) and NI group (70%), P < 0.05. CONCLUSIONS: The model fully simulated the key damage factors and field treatment conditions, reflected the effects of low temperature and hypertonic damage caused by seawater immersion on the severity and prognosis of naval combat wounds, and provided a practical and reliable animal model for the study of field treatment technology of marine combat shock.

OBJECTIVE: To observe the effect of acupotomy on the fat infiltration degree of lumbar multifidus muscle (LMM) in patients with lumbar disc herniation after percutaneous transforaminal endoscopic discectomy (PTED). METHODS: A total of 104 patients with lumbar disc herniation treated with PTED were randomly divided into an observation group (52 cases, 3 cases dropped off) and a control group (52 cases, 4 cases dropped off). Patients of both groups received rehabilitation training of two weeks 48 h after PTED treatment. The observation group was treated with acupotomy (L3-L5 Jiaji [EX-B 2]) once within 24 h after PTED. In the two groups, the fat infiltration cross sectional area (CSA) of LMM was compared before and 6 months after PTED, the visual analogue scale (VAS) score and Oswestry disability index (ODI) score were observed before and 1, 6 months after PTED. The correlation between fat infiltration CSA of LMM in each segment and VAS score was analyzed. RESULTS: Six months after PTED, the fat infiltration CSA of LMM in L4/L5 and the total L3-S1 segments of the observation group was lower than that before PTED (P<0.05), and the fat infiltration CSA of LMM in L4/L5 of the observation group was lower than the control group (P<0.01). One month after PTED, the ODI and VAS scores of the two groups were lower than those before PTED (P<0.01), and those in the observation group were lower than the control group (P<0.05). Six months after PTED, the ODI and VAS scores of the two groups were lower than those before PTED and 1 month after PTED (P<0.01), and those in the observation group were lower than the control group (P<0.01). There was a positive correlation between the fat infiltration CSA of LMM in the total L3-S1 segments and VAS scores in the two groups before PTED (r = 0.64, P<0.01). Six months after PTED, there was no correlation between the fat infiltration CSA of LMM in each segment and VAS scores in the two groups (P>0.05). CONCLUSION: Acupotomy can improve the fat infiltration degree of LMM, pain symptoms and activities of daily living in patients with lumbar disc herniation after PTED.

OBJECTIVE: To observe clinical effects of platelet-rich plasma (PRP) intra-articular and extra-articular injection for patients with knee osteoarthritis (KOA), and analyze its safety and clinical efficacy. METHODS: From January to December 2017, 48 patients with KOA were randomly divided into observation group and control group, 24 cases in each group. The observation group was treated with intra-articular injection of PRP (2 ml) and extra-articular injection of PRP (2 ml), once a week, for three times, including 8 males and 16 females with an average of (58.04±7.87) years old ranging from 43 to 68 years old, the courses of disease ranged from 1 to 8 years with an average of (4.69±1.96) years, the body mass index (BMI) was (24.53±5.26) kg/m 2 . The control group was treated with intra-articular injection of sodium hyaluronate (20 mg), extra-articular injection of analgesic drug (2 ml for one point), once a week, for three times, including 7 males and 17 females with an average of (60.54±8.93) years old ranging from 47 to 72 years old, the courses of disease ranged from 1.5 to 9 years with an average of (5.27±1.68) years, BMI was (23.47±4.62) kg/m 2 . VAS score and Lysholm score before operation and the 1st, 6th month after treatment were compared between two groups. RESULTS: All patients were followed up at least 6 months without occurrence serious adverse reactions or complications. VAS score in observation group and control group before treatment and 1st, 6th month after treatment were 7.35±1.47, 4.15±1.52, 2.26±1.02 and 7.51±1.39, 3.84±1.76, 3.66±1.18, respectively; VAS score in obsevation group was lower than that of control group at 6 months after treatment. Lysholm score in observation group and control group before treatment and 1st, 6th month after treatment were 55.21±5.78, 79.16±7.25, 85.45±6.87 and 54.65± 6.40, 77.58±6.94, 82.34±7.12. There were significant differences in Lysholm score before and after injection between two groups (P<0.05) . There was no significant difference in Lysholm score between two groups at 1 month after treatment (P>0.05), while Lysholm score in observation group was better than that of control group at 6 months after treatment (P<0.05) . CONCLUSION: Intra-articular and extra-articular injection of PRP could relieve pain symptoms and improve function of knee joint with higher safety, although the short-term effect is not significantly different from traditional treatment, its medium-long-term effect is stable. It is a safe and effective method for the treatment of knee osteoarthritis.

BACKGROUND: A few studies have noted that paraspinal muscle training is important to reduce pain for patients with lumbar disc herniation (LDH). However, little is known about the exact signs for necessary training of lumbar multifidus muscles (LMM). OBJECTIVE: The study aimed to analyze the relationship between the straight leg-raising test (SLR) and the area of fat infiltration in LMM for patients with LDH. METHOD: One hundred and fourteen LDH patients were involved in this study. Clinical data were collected from a medical record system. On the MRI images, the cross-sectional areas (CSA) of bilateral fat infiltration in LMM were measured by picture archiving and communication system (PACS). RESULT: For 61 patients with inclusive LDH, the positive side of SLR was positively correlated with the side of the larger total CSA of fat infiltration in LMM of L2-S1 (r= 0.75, pâ¢ï⢻⢠0.01), and the CSA of fat infiltration on the side of SLR with a positive result was significantly larger than that on the side of SLR with a negative result only at L3-4 and L4-5 levels (pâ¢ï⢻⢠0.01). CONCLUSION: SLR may be used as an important sign for dysfunction of LMM and can identify the more severe side.

Electroacupuncture (EA) at ST36 can improve the survival rate in rats after hemorrhagic shock (HS). The current study investigated rats with 60% blood loss. 144 rats were divided into four groups: hemorrhage without fluid resuscitation (HS), EA after hemorrhage without fluid resuscitation (EA), hemorrhage with delayed resuscitation (DFR), and EA after hemorrhage with delayed resuscitation (EA + DFR). The survival rate and biological parameters 0, 3, 12, and 24 h after HS were investigated. The 24 h survival rate of EA + DFR was significantly higher than that of DFR. 12 h after hemorrhage, the level of mean arterial blood pressure of EA + DFR was significantly higher than that of DFR, and the levels of renal blood flow, intestinal mucosal blood flow, and hepatic blood flow of EA + DFR were also significantly higher than those of DFR. Three hours after hemorrhage, the levels of lactate, PaCO2, alanine aminotransferase, and creatinine of groups receiving EA were significantly lower than those of non-EA groups, and the levels of pH, PaO2, and diamine oxidase of groups receiving EA were significantly higher. EA at ST36 can improve the 24 h survival rate and produce the experimental antishock effects on tissue perfusion and organ protection from fatal HS.
ABSTRACT
OBJECTIVE: To explore the clinical effect of exercise rehabilitation during perioperative period on residual pain, gait and activities of daily living (ADL) in patients with lumbar spinal stenosis (LSS) after lumbar percutaneous transforaminal endoscopic discectomy(PTED). METHODS: The clinical data of 48 patients with LSS underwent PTED from December 2015 to December 2016 were retrospectively analyzed. Patients were divided into observation group and control group according to different rehabilitation patterns, being 24 cases in each group. The patients of observation group received exercise rehabilitation and the patients of control group received conventional rehabilitation. Visual analogue scale(VAS), Oswestry Disability Index (ODI) and the ratio of supporting phase were recorded before operation and 12 days, 6 months after operation. The correlation between the ratio of supporting phase and VAS, ODI was analyzed. RESULTS: The ratio of supporting phase of observation group was significantly higher than that of control group at 12 days after operation(P<0.05). The VAS and ODI in observation group were significantly lower than that of control group at 6 months after operation(P<0.01). There was no correlation between the ratio of supporting phase and ODI or VAS in two groups (P>0.05). CONCLUSIONS: Lumbar percutaneous transforaminal endoscopic discectomy combined with exercise rehabilitation during the perioperative period can release or eliminate postoperative residual pain, improve gait balance, enable activities of daily living, and has a positive effect in patients with lumbar spinal stenosis.

Sixty Sprague-Dawley rats were divided into 5 groups: (a) control group (HS); (b) Immediate rehydration group (IFR); (c) ST36 electroacupuncture (EA) delay rehydration group (EA/DFR): EA at ST36 immediately after blood loss with infusion 3 h later; (d) EA nonmeridian rehydration group (SEA/DFR): EA at nonacupuncture sites with rehydration similar to EA/DFR; (e) ST36 EA group (EA): EA at ST36 immediately after blood loss with no rehydration. Forty-five percent of the entire blood volume was taken out to make lethal hemorrhagic shock models. We recorded the survival rate, intestinal tissue DAO content, and microcirculation. The survival rate of the EA/DFR group and the IFR group was significantly higher than that of the other three groups (P < 0.05). Twelve hours after blood loss, intestinal tissue DAO content of the EA/DFR group and the IFR group was significantly higher than that of the SEA/DFR group, EA group, and HS group (P < 0.05 and P < 0.01). The mucosal blood flow of the EA/DFR group and the IFR group was significantly higher than the other groups (P < 0.05 each). We conclude that EA improves the blood pressure and raises the early survival rate of hemorrhagic shock rats, maintains the intestinal barrier function, and improves the degree of intestinal ischemia.
ABSTRACT
OBJECTIVE: To investigate the effects of electroacupuncture at "Zusanli" (ST 36) on the volume of hepatic blood flow, water ratio and plasma alanine aminotransferase (ALT) in rats with delayed fluid replacement after hemorrhagic shock and to provide the references for electroacupuncture at Zusanli (ST 36) in treating hemorrhagic shock. METHODS: Forty SD rats with hemorrhagic shock induced by bloodletting 40% of whole blood volume were randomly divided into a hemorrhage with no treatment (NT) group, an immediate fluid replacement (IFR) group, an electroacupuncture at Zusanli (ST 36) and delayed fluid resuscitation (EA/DFR) group and a sham electroacupuncture and delayed fluid replacement (SEA/DFR) group, 10 rats in each group. No treatment was performed in NT group. IFR group was treated with fluid replacement at 10 minutes after blood loss, and EA/DFR group was treated with electroacupuncture at "Zusanli" (ST 36) at 10 minutes after blood loss, while non-acupoint was punctured in SEA/DFR group. Two EA groups were received delayed fluid replacement at 3 hours after blood loss. The volume of hepatic blood flow and ALT before blood loss and 3 h and 12 h after blood loss, and water ratio 12 h after blood loss were measured. RESULTS: After blood loss, all parameters in IFR group and EA/DFR group were improved significantly in contrast with those in NT group (all P < 0.05). There was no significant difference between SEA/DFR group and NT group. Three hours after blood loss, the hepatic blood flow of IFR group was significant higher than those of NT group, EA/DFR group and SEA/DFR group (all P < 0.05), while the plasma ALT of IFR group was significant lower than those of NT group, EA/DFR group and SEA/DFR group (all P < 0.05), and the plasma ALT of EA/DFR group was lower than those of NT group and SEA/DFR group (both P < 0.05), the hepatic blood flow of EA/DFR group showed no significant difference compared with that of SEA/DFR group (P > 0.05). Twelve hours after blood loss, the plasma ALT and the water ratio of EA/DFR group and IFR group were significant lower than those of NT group and SEA/DFR group (all P < 0.05), and the hepatic blood flow of EA/DFR group and IFR group was significant higher than those of NT group and SEA/DFR group (all P < 0.05), while the plasma ALT of IFR group was significant lower than that of EA/DFR group (P < 0.05), and the hepatic blood flow of IFR group was significant higher than that of EA/DFR group (P < 0.05). CONCLUSION: Electroacupuncture at "Zusanli" (ST 36) has a protective effects for hepatic ischemic injury in rats with delayed fluid replacement after hemorrhagic shock.

OBJECTIVE: To observe the protective effect of electroacupuncture (EA) at "Zusanli" (ST 36) on inflammatory injury induced by intestinal ischemia/reperfusion (I/R) in rats. METHODS: Forty-eight Wistar rats were randomly divided into a sham injury group, a model group, an EA group and a sham EA group, 12 rats in each group. Intestinal I/R rat models were established by method of clamping with occlusion of superior mesenteric artery (SMA) for 45 min followed by reperfusion. The EA group was treated with EA (2.5 mA, 2 Hz/100 Hz, 0.5 h) at "Zusanli" (ST 36) 30 min before reperfusion, and at the same time, the sham EA group was treated with fast insertion at two non-meridian acupoints on skin surface (2 cm horizontally away from linea alba abdominis and about 5 cm paralleled to cartilago ensiformis downward). No interventions were added on the sham injury group and the model group. The degree of pathological injury in intestines, water rate of intestines, diamine oxidase (DAO) activity and intestinal mucosal blood flow (IMBF) were examined at 1 h and 3 h after reperfusion. RESULTS: At 1 h and 3 h after reperfusion, the intestinal pathological injury in EA group was significantly attenuated compared with that in model group, and the intestinal water rate of (74.00 +/- 2.11)% and (78.78 +/- 0.80)% in EA group were significantly lower than (80.69 +/- 1.66)% and (83.17 +/- 2.08)% in model group (both P < 0.01), but DAO of (68.83 +/- 4.31) U/L and (47.84 +/- 5.57) U/L as well as IMBF of (152 +/- 5.8) PU and (139.8 +/- 6.1) PU in EA group were significantly higher than DAO of (32.86 +/- 4.72) U/L, (17.01 +/- 2.96) U/L as well as IMBF of (124.7 +/- 8.3) PU and (89.4 +/- 13.2) PU in model group (all P < 0.01). Meanwhile, the above mentioned changes in sham EA group showed no significant differences compared with those in model group (all P > 0.05). CONCLUSION: Electroacupuncture can not only reduce the inflammatory injury induced by intestinal IR but also increase intestinal blood supply so as to protect the intestine function.
