Objective To study the serum enzyme in the adult central nervous system infection in patients and its clinical significance,aimed at providing basis for the diagnosis and prognosis of the adult central nervous system infection. Methods 68 patients with central nervous system infections were treated in June 2008 to Decem 2009 in Neurology Department of our hospital. In addition, 60 healthy persons were selected at the same time as control group. Serum aspartate aminotransferase ( AST), lactate dehydrogenase ( LDH) , Creatine kinase ( CK) , CK-MB ( CK-MB)levels were detected. Results AST,LDH,CK and CK-MB levels of the central nervous system infection group were higher than the control group,and the difference between the two groups was statistically significant(P<0.05). Severe group AST, LDH, CK and CK-MB and other content of the four enzymes were higher, and the difference between the two groups is also significant ( P < 0.05 ). Conclusions Adult patients with central nervous system infection significantly increased serum enzyme levels, and serum enzyme levels had a positive correlation with the severity. Serum enzyme was a reliable adult central nervous system infections diagnostic index.

Objective·To investigate correlation of serum acute amyloid A (A-SAA) level and activity of Behcet's disease (BD).Methods·Blood samples from patients with active BD (n=40),remission BD (n=15),Takayasu disease (TA,n=12),rheumatoid arthritis (RA,n=25),systemic lupus erythematosus (SLE,n=25) and healthy donor (HD,n=25) were collected.Serum A-SAA,ESR,and CRP levels were detected and compared among groups.The correlation between A-SAA and its downstream IL-8 or International Society for Behcet's disease (ISBD) disease activity scores was analyzed as well.Results·Serum A-SAA level was significantly increased in the patients with active BD [(115.70±87.78) mg/L],as well as patients with RA and TA,which levels were (68.72±61.50) mg/L and (96.25±87.41) mg/L respectively,but remained unchanged in SLE patients.Moreover,serum A-SAA level was found correlated with ISBD score as well as IL-8 level.Conclusion·A-SAA can work as a detection index for evaluating BD activity.

Objective To determine whether or not 810 nm low power Ga-Al-As laser treatment can stimulate the regeneration of damaged optic nerves by measuring the expression of growth associated protein 43 ( GAP-43 )and flash-visual evoked potential (F-VEP). Methods Eighty-eight Wistar rats weighing (180-220) g were randomly divided into a laser therapy group with 40 rats,an injury group with 32 rats,and a normal control group with 16 rats.Each group was subdivided into 1st,3rd,6th and 9th week subgroups.A standardized crushing of the optic nerve was applied to make the model.After this,the laser therapy group was treated for 3 minutes daily at 60 mW applied transcutaneously to a 5 mm diameter spot on the injured optic nerve.The injury and normal control groups received the same treatment with no laser output.The expression of GAP-43 was detected by immunohistochemistry and RT-PCR after 1,3,6 and 9 weeks of treatment.F-VEP was measured pre-injury,immediately after injury and 1,3,6 and 9 weeks post injury. Results After the optic nerve was injured,obvious changes in F-VEP were detected,including significantly prolonged latencies of N1,P1 and N2 waves.The latency increased immediately after the optic nerve injured,and then recovered,but after 1 and 3 weeks the latency was still prolonged.There was significant recovery from the 3rd to the 9th week.In the laser therapy group,the peak latencies of the N1,P1 and N2 waves were also prolonged,but the changes were less than those in the injury group.Expression of GAP-43 was hardly detectable in normal retinas and optic nerves.GAP-43 had its highest expression level at 1 week post-injury,and then decreased.At the 1st,3rd and 6th week post-injury,the expression of GAP-43 in the laser therapy group was significantly higher than in the injury group.GAP-43 mRNA content in the retina showed the same tendency as GAP-43 protein. Conclusion A 810 nm low power Ga-Al-As laser can promote neural repair and axonal regeneration after optic nerve injury.

Objective To explore the effect of soluble tyrosine kinase 2 fusion protein (sTie-2-Fc) on peritoneal angiogenesis, solute transport and ultrafi]tration capacity in uremic rats undergoing peritoneal dialysis (PD). Methods Thirty-two male Wistar rats were randomly divided into sham-operation group, uremic group, uremic PD group, and sTie-2-Fc group (all n=8).Uremic PD group and sTie-2-Fc group received intraperitoneal infusion of 3 ml/100 g of peritoneal dialysis fluid (PDF) containing 4.25% glucose twice daily for 4 weeks. Rats in sTie-2-Fc group were infused with PDF supplemented with 1 μg sTie-2-Fc. Before the rats were sacrificed, a peritoneal equilibration test (PET) was performed to evaluate the peritoneal solute transport and ultrafiltration capacity, and omenta was obtained for anti-CD31 immunohistochemical staining to determine the vessel density. Results Compared to their counterparts in sham-operation group,rats in uremic group had higher 2 h-dialysate to plasma creatinine concentration ratio (D/Pcr, 0.78±0.05 vs 0.70±0.09, P=0.028), lower 2 h to initial dialysate glucose concentration ratio (D/D0, 0.69±0.05 vs 0.76±0.07, P=0.033), decreased peritoneal ultrafiltration [UF, (2.29±0.50) ml vs (4.58±1.64) ml, P=0.005], and increased omental vessel density [(5.8±3.0)/HP vs (1.6±0.5)/HP, P＜0.01]. When compared to uremic group, rats in uremic PD group showed higher D/Pcr (0.89±0.05 vs 0.78±0.05, P=0.001), lower D/D0 (0.47±0.09 vs 0.69±0.05, P＜0.01), decreased UF [(0.40±0.59) ml vs (2.29±0.50) mi, P=0.005] and more omental vessels [(16.7±1.2)/HP vs (5.8±3.0)/HP, P＜0.01]. Improved peritoneal UF [(1.56±0.48) ml vs (0.40±0.59) mi, P=0.014] and decreased omental vessels [(9.2± 1.2)/HP vs (16.7 ± 1.2)/HP, P＜0.01] were observed in rats treated with sTie-2-Fc compared with those in uremic PD group, however, the differences of D/Pcr (0.87±0.06 vs 0.89±0.05, P=0.122) and D/D0 (0.60±0.11 vs 0.47±0.09, P=0.06) between these two groups did not reach statistical significance. Conclusion sTie-2-Fc preserves peritoneal ultrafiltration capacity and ameliorates peritoneal angiogenesis caused by uremia and exposure to bioincompatibal PDF.

Objective To explore the analgesic effect of intra-articular botulinum neurotoxin type A (BoNTA) injection in rats with adjuvant-arthritis pain,to quantify the expression of calcitonin gene-related peptide (CGRP) in the dorsal root ganglia (DRG) associated with arthritis pain,and to investigate the retrograde axonal transport of BoNT-A into the DRG after peripheral injection.Methods Ninety Sprague-Dawley rats were randomly divided into groups A,B,C,D and E,each of 18.A murine model of adjuvant-arthritis pain was established by injecting 50 μL of complete Freund's adjuvant into the left ankle in all the mice except those in group A.The control group A was treated with intra-articular injection of 50 μL of saline solution.Three weeks later,groups A and B were treated with a 20 μL intra-articular saline injection,while groups C,D and E received an intra-articular injection of BoNT-A at 1 U/20 μL,3 U/20 μL or 10 U/20 μL respectively.Pain threshold and muscle strength were graded before and 1,5,15 and 21 days after the modelling,as well as at 1,3,5 and 14 days after the BoNT-A treatments.Protein expression and the CGRP-positive cell number were observed,as well as any BoNT-A-cleaved synaptosomal-associated 25 kDa protein (cl-SNAP-25) in the DRG using Western blotting and immunofluorescence.Results Compared with group A,there was a significant decrease in the average mechanical withdrawal threshold and muscle strength and a significant increase in the protein expression and the CGRP-positive cell number in the other 4 groups.Compared with group B,the mechanical withdrawal threshold had increased significantly more in groups D and E at 5 days after the BoNT-A injection and in group C at 14 days after the treatment.Compared with group B,the protein expression and the number of CGRP-positive cells were significantly lower in groups D and E at 3 days after the BoNT-A injection.The decrease in group C was significant after 14 days.No significant differences were found between groups D and E in any measurement at any time point.There was no significant difference among groups B,C and D in terms of muscle strength.Five days after the BoNT-A injection,significantly decreased muscle strength was observed in group E.In addition,BoNT-A cleaved-SNAP-25 was detected in the DRG.Conclusion BoNT-A can reduce arthritis pain through inhibiting the expression of CGRP in the DRG.Its analgesic effect has a dose response.A peripheral injection of BoNT-A can arrive at the DRG through retrograde axonal transport.

OBJECTIVE: To improve the understanding of the symptoms and signs of isolated sphenoid sinus disease and decrease the occurrence of misdiagnoses. METHOD: The clinical manifestation and the advantage of endoscopic sinus surgery were analyzed in 22 cases of isolated sphenoid sinus disease. RESULT: Twelve cases had endoscopic sphenoidotomy, 7 cases had external ethmoidal sphenoidotomy, 3 cases had antibiotic, steroid and neurotrophic therapy. All of the patients were free of headache,improvement in vision and ocular motility after treatment. After 3 to 6 months' follow up, 1 case recurred and symptom relieved after endoscopic sinus surgery. 1 case adenoid cystoid carcinoma underwent post operative radiotherapy without recurrence after 3 years follow up. CONCLUSION Isolated sphenoid sinus disease presented the primary symptom as headache and/or ocular disturbance is prone to be misdiagnosed, application of CT, MRI and endoscopy improve its diagnosis and treatment standard. Endoscopic sinus surgery is the primary therapy for isolated sphenoid sinus disease.

OBJECTIVE To explore the efficiency of reducing post-tonsillectomy hemorrhage by increasing blood pressure before the end of the coblation operation.METHODS Clinical data of 1069 patients with coblation assisted tonsillectomy under general anesthesia between January 2008 and January 2016 were retrospectively reviewed.The treatment group were 546 patients checked the operation cavity after increasing blood pressure before the end of tonsillectomy,while the control group were 523 patients checked the operation cavity with routine procedure without increasing the blood pressure.Post-tonsillectomy hemorrhage incidence and postoperative bleeding volume were compared between the two groups.RESULTS Checking the operation cavity after increasing blood pressure before the end of tonsillectomy can reduce the incidence of postoperative primary hemorrhage (P＜0.05),but cannot reduce the incidence of postoperative secondary hemorrhage (P＞0.05).CONCLUSION Increasing blood pressure before the end of tonsillectomy can effectively reduce the incidence of postoperative primary hemorrhage.

Objective:To introduce the operation process of laparoscopic total gastrectomy assisted by small incision and gastrointestinal reconstruction using tubular instrument anastomosis in esophageal and small bowel reconstruction, and evaluate its feasibility, safety during perioperative period, and advantages of anastomosis.Methods:A total of 56 patients with gastric cancer who underwent laparoscopic total gastrectomy assisted by small incision and gastrointestinal reconstruction using tubular instrument anastomosis in esophageal and small bowel reconstruction were selected as study subjects from Zhejiang Provincial People′s Hospital between May 2022 and June 2023. Gender, age, body mass index (BMI), tumor location, tumor stage, tumor type and other related indicators were collected. The main parameters during the operation process were collected, including operation time, anastomosis time, intraoperative blood loss, postoperative recovery status, exhaust time, feeding time, complications related to anastomosis, and length of hospital stay. The differences between other digestive tract reconstruction methods such as Overlap method, reverse puncture method, and handmade anastomosis were compared and analyzed.Results:A total of 56 patients with gastric cancer were included in this study. The anastomosis time of the tubular instrument group was (42.3±15.7)min, which was superior to the handmade anastomosis group ( P<0.05). The operation time of the tubular instrument group was (176.3±25.8)min, which was superior to other methods (all P<0.05). The intraoperative blood loss of the tubular instrument group was (75.68±20.34)ml, which was less than other methods (all P<0.05). The exhaust time of the tubular instrument group was (2.6±0.2)d, which was similar to the Overlap method ( P>0.05), but earlier than the handmade anastomosis method and the reverse puncture method (all P<0.05). The incidence of anastomotic leakage in the tubular instrument group was similar to the handmade anastomosis method, the reverse puncture method, and the Overlap method (all P>0.05). There were no significant differences in postoperative hospital stay, incision infection rate, and other complications related to anastomosis between groups (all P>0.05). Conclusions:The tubular instrument anastomosis method has a shorter operation time and a smaller incision compared to traditional laparotomy surgery. It has the advantages of laparoscopic assistance with intuitive and clear visualization during the operation, while also taking into account the convenience and safety of direct visualization under laparoscopy. It is a surgical method worthy of promotion.

Objective:To investigate the clinical effect of enteral nutrition support in the transformation therapy of advanced gastric cancer.Methods:Eighty-two patients with advanced gastric cancer treated by transformation in Zhejiang Provincial People′s Hospital from September 2019 to August 2021 were analyzed retrospectively. 41 patients in the observation group were treated with enteral nutrition support on the basis of routine transformation treatment; 41 patients in the control group received only routine transformation treatment. The nutritional related indexes such as prealbumin, total serum protein and albumin and immune related indexes such as CD4 + , CD8 + , CD4 + /CD8 + were detected before treatment and on the 7th day after the end of 3-cycle transformation treatment, and the above indexes and transformation success rate of the two groups were compared. Results:There was no significant difference in prealbumin, total serum protein, albumin, CD4 + , CD8 + , CD4 + /CD8 + between the two groups before treatment (all P>0.05). On the 7th day after three cycles of transformation treatment, the above indexes in the observation group were higher than those in the control group, with significant difference (all P<0.05). The success rate of transformation in the observation group was higher than that in the control group ( P<0.05). Conclusions:The rational use of enteral nutrition support in the transformation treatment of patients with advanced gastric cancer can significantly improve the nutritional status and immune function of patients, increase the tolerance to chemotherapy and improve the success rate of transformation.

Nonalcoholic fatty liver disease (NAFLD) is a genetic and environmental factor-associated metabolic disease that can lead to fibrosis, cirrhosis and hepatocellular carcinoma. In recent decades the prevalence of NAFLD has increased, but effective pharmacotherapy is limited. Treatment regimens in traditional Chinese medicine (TCM) have made significant contributions to the control of NAFLD, but underlying mechanisms are far less elucidated. Increasing evidence suggests that gut microbiota play a crucial role in the pathogenesis and development of diseases including NAFLD. The outcomes of such research open a new approach in identifying the molecular mechanisms of TCM. Here we review the evidence that gut microbiota might be a target in the treatment NAFLD using TCM.
