Objective To evaluate the effect of sevoflurane postconditioning on microRNA-133a (miR-133a) expression during myocardial ischemia-reperfusion (I/R) in mice.Methods Thirty adult male C57 mice,weighing 20-30 g,were randomized to 3 groups (n =10 each) using a random number table:control group (group C),I/R group,and sevoflurane postconditioning group (group SP).In I/R and SP groups,hearts from adult male C57 mice were exposed and subjected to 30 min of ischemia and 180 min of reperfusion in anesthetized mice according to the method described by Das et al.In group C,only thoracotomy was performed without ligation of the coronary artery.In group SP,2.4％ sevoflurane was inhaled for 5 min starting from the onset of reperfusion to perform sevoflurane postconditioning.At 180 min of reperfusion,blood samples from the femoral vein were collected for determination of serum lactic dehydrogenase (LDH) and creatine kinase (CK) activities using the colorimetric method.The mice were then sacrificed,and myocardial specimens were obtained for determination of myocardial infarct size,miR133a and caspase-9 mRNA expression (by real-time reverse transcriptase polymerase chain reaction),and caspase-9 expression (by Western blot).Results Compared with group C,the serum LDH and CK activities and myocardial infarct size were significantly increased in I/R and SP groups,the expression of miR-133a was significantly down-regulated,and the expression of caspase-9 protein and mRNA was significantly up-regulated in group I/R,and the expression of miR-133a and caspase-9 protein and mRNA was significantly up-regulated in group SP (P＜0.05).Compared with group I/R,the serum LDH and.CK activities and myocardial infarct size were significantly decreased,the expression of miR-133a was significantly up-regulated,and the expression of caspase-9 protein and mRNA was significantly downregulated in group SP (P＜0.05).Conclusion The mechanism by which sevoflurane postconditioning inhibits cell apoptosis during myocardial I/R is related to up-regulation of miR-133a expression in mice.

BACKGROUND:Spine minimaly invasive technique through foraminal mirror is the method to treat lumbar disc herniation with minimal wound. This technique can be conducted under local anesthesia, and does not need to resect the smal joint or destroy the vertebral plate, and has smal damage to the spine. OBJECTIVE: To explore the short-period effects of transforaminal endoscopic spine system for adjacent-segment degenerative changes-caused low back pain after lumbar fixation and fusion. METHODS:A total of 31 patients with degenerative changes after posterior lumbar bone graft fusion fixation, who required secondary surgery, were enroled in this study, including 23 males and 8 females, at the age of 45-81 years old. The postoperative time was 1.1-5.7 years. There were 3 cases of L3-4 single segment, 15 cases of L4-5 single segment, 8 cases of L5S1 single segment, and 5 cases of multi-segment. These patients were treated with transforaminal endoscopic spine system, and folowed up for 6 months. Visual Analogue Scale score and lumbar function Japanese Orthopedic Association score were observed. RESULTS AND CONCLUSION: Lumbar and leg pain symptoms were relieved noticeably during the operation. The patient could walk immediately after the surgery, and the postoperative recovery was quite satisfactory. Visual Analogue Scale score was lower immediately, 1, 3 and 6 months after treatment compared with pre-treatment. Lumbar function Japanese Orthopedic Association score was higher immediately, 1, 3 and 6 months after treatment compared with pre-treatment. Results verify that transforaminal endoscopic spine system for degenerative changes after posterior lumbar bone graft fusion fixation has some advantages such as high safety, short operation time, less hemorrhage, less complications, rapid restoration and easily accepted by patients.

Objective To evaluate the role of Janus kinase 2-signal transducer and activator of transcription 3 (JAK2-STAT3) signaling pathway in sevoflurane postconditioning-induced inhibition of mitochondrial permeability transition pore (mPTP) opening during myocardial ischemia-reperfusion (I/R)in rats.Methods Sixty pathogen-free healthy male Sprague-Dawley rats,weighing 250-300 g,were divided into 4 groups (n=15 each) using a random number table:I/R group,sevoflurane postconditioning group (group SP),AG-490 group (group AG) and sevoflurane postconditioning plus AG-490 group (group SP+AG).Myocardial I/R was induced by 30 min ligation of the left anterior descending branch of coronary artery followed by 120 min reperfusion.In group SP,2.8％ sevoflurane was inhaled for 15 min starting from 2 min before reperfusion.JAK2 inhibitor AG-490 3 mg/kg was intravenously injected at 10 min before reperfusion in group AG.In group SP+AG,AG-490 3 mg/kg was intravenously injected at 10 min before reperfusion,and 2.8％ sevoflurane was inhaled for 15 min starting from 2 min before reperfusion.At 15 min of reperfusion,5 rats were sacrificed and myocardial specimens were obtained for determination of the expression of JAK2,phosphorylated JAK2 (p-JAK2),STAT3 and phosphorylated STAT3 (p-STAT3)in myocardial tissues by Western blot.The ratios of p-JAK2 to JAK2 expression (p-JAK2/JAK2) and pSTAT3 to STAT3 expression (p-STAT3/STAT3) were calculated.Five rats were sacrificed at the end of reperfusion for measurement of myocardial infarct size.The left 5 rats were selected and sacrificed,myocardial specimens were obtained,and the opening of mPTP was detected by a calcein-cobalt quenching method.Results Compared with group I/R,the myocardial infarct size and mPTP opening were significantly decreased,and JAK2/p-JAK2 and STAT3/p-STAT3 were increased in group SP (P＜0.05),and no significant change was found in the parameters mentioned above in SP+AG and AG groups (P＞0.05).Compared with group SP,the myocardial infarct size was significantly enlarged,the extent of mnPTP opening was aggravated,and JAK2/p-JAK2 and STAT3/p-STAT3 were decreased in SP+AG and AG groups (P＜0.05).Conclusion The mechanism by which sevoflurane postconditioning inhibits the opening of mPTP during myocardial I/R is related to activation of JAK2-STAT3 signaling pathway in rats.

OBJECTIVETo investigate the expression of angiopoietin-2 (Ang-2) and its clinical significance in oral squamous cell carcinoma.

METHODSThe expression of Ang-2 mRNA was measured by real-time RT-PCR, and the expression of Ang-2 protein in tissue samples was detected by immunohistochemical staining.

RESULTSThe mean dCt value of Ang-2 mRNA expression in the cancer tissue was 6.86 +/- 1.37, significantly lower than that in the paired adjacent non-cancerous tissue (7.95 +/- 2.08, P < 0.05), indicating a significantly higher expression of Ang-2 mRNA in the cancerous tissue than that in the adjacent non-cancerous tissue. The distribution of Ang-2 protein was found not only in the vascular endothelial cells but also in tumor cells. Semi-quantitative analysis revealed that the expression of Ang-2 protein in tumor specimens (53.6%) was significantly higher than that (24.0%) in the paired adjacent non-cancerous tissue (P < 0.05), the result was well consistent with that measured by RT-PCR. The dCt value of Ang-2 mRNA expression was 6.48 +/- 1.16 in the patients with metastasis in lymph nodes versus 7.16 +/- 1.49 in those without, with a non-significant difference between the two groups (P > 0.05). As regards the clinical stages, no significant difference was found between the expressions of Ang-2 mRNA in stage I + II (7.11 +/- 1.63) and stage III + IV cases (6.49 +/- 1.10, P > 0.05).

CONCLUSIONAngiopoietin-2 protein is expressed not only in vascular endothelial cells, but also in tumor cells, suggesting that angiopoietin-2 may take part in angiogenesis in oral squamous cell carcinoma. However, our results that high expression of angiopoietin-2 mRNA is not correlated with lymph node metastasis and clinical stages, needs to be further verified in a large scale study.

Objective To investigate the effect and possible mechanism of bone marrow stem cell mobilized by stem cell factor (SCF) with granulocyte colony-stimulating factor(G-CSF)on renal peritubular capillary, fibrosis and renal function in unilateral ureteral obstruction (UUO) rats. Methods One hundred and twenty eight healthy male Wistar rats were randomly divided into four groups: Sham group, SCF-G group, UUO group and UUO+SCF-G group. Eight rats of each group were randomly selected and killed on the 5th, 14th, 21st and 28th day. Serum creatinine, CD34 positive cells and factor Ⅷ positive cells in renal interstitium, histopathologic lesion scores of interstitial fibrosis and interstitial pathology in kidney were measured. The mRNA expression of vascular endothelial growth factor (VEGF). and thrombospondin-1 (TSP-1) in the renal cortex was detected. Results (1) The renal interstitial fibrosis anti the loss of peritubular capillary were observed in UUO group after two weeks. (2) The number of bone marrow stem cells homing to renal interstitium in UUO +SCF-G group was significantly higher than that in UUO and Sham groups (P<0.05). (3) The loss of peritubular capillary in UUO+SCF-G group appeared later than that in UUO group (P<0.05). (4) The interstitial fibrosis and tubule injury was milder in UUO+SCF-G group than that in UUO group (P<0.05). (5) The decrease of VEGF mRNA expression of renal cortex in UUO +SCF-G group was seen later than that in UUO group. VEGF mRNA expression in UUO+SCF-G group was higher than that in UUO group. (6) The increase of TSP-1 mRNA expression of renal cortex in UUO+SCF-G group was seen later than that in UUO group. TSP-1 mRNA expression in UUO+SCF-G group was lower than that in UUO group (P<0.05). (7) In UUO and UUO+SCF-G groups, peritubular capillary index was negatively correlated with serum creatinine, interstitial fibrosis and interstitial lesion scores. VEGF mRNA expression of renal cortex was positively correlated with peritubular capillary index, and TSP-1 mRNA expression of renal cortex was positively correlated with peritubular capillary index. Conclusions (1)The loss of peritubular capillary is found in UUO group, and is correlated with interstitial fibrosis and interstitial lesion. (2) Application of SCF with G-CSF can effectively motivate stem cells to injured renal tissue, contribute to decrease the loss of peritubular capillary, lessen interstitial fibrosis and interstitial lesion, and ameliorate renal function. (3) Application of SCF with G-CSF can up-regulate VEGF mRNA expression and down-regulate TSP-1 mRNA expression, which may contribute to promote the repair of endothelial cells and protect peritubular capillary.

BACKGROUNDHerpes simplex keratitis (HSK) caused by herpes simplex virus 1 (HSV-1), which has high recurrent rate and incidence of severe vision loss, is the leading cause of infectious blindness in the world. The aim was to explore the clinical efficacy of oral ganciclovir (GCV) in the prevention of recurrent HSK.

METHODSA multicenter, prospective, randomized, single-blind, and controlled clinical trial was conducted from April 2010 to June 2013. One hundred seventy-three patients (173 eyes involved) who were diagnosed as recurrent HSK definitely, including stromal keratitis and corneal endotheliitis, were divided into three groups randomly: negative control (placebo) group was topically administered with 0.15% GCV ophthalmic gel, 4 times per day and 0.1% fluorometholone eye drops, 3 times per day until resolution of HSK; positive control acyclovir (ACV) group was topically adopted the same ophthalmic gel and eye drops and additionally received oral ACV 400 mg 5 times a day for 10 weeks and followed by 400 mg 2 times per day for 6 months; test GCV group was topically adopted the same treatment as negative control group and additionally received oral GCV 1000 mg 3 times per day for 8 weeks. The symptoms and signs were evaluated before and after the therapy 1 st week, 2 nd week and then followed up every 2 weeks until recovery. Furthermore, we followed up recurrence of HSK for every 3 months after recovery and then assessed the cure time, recurrent rate and adverse reactions.

RESULTSOne hundred and seventy-three patients were followed up 7-48 months (mean 32.1 ± 12.3 months), but 34 patients were failed to follow-up. The cure time was 12.1 ± 4.3, 11.9 ± 4.0 weeks in negative control (placebo) group and positive control ACV group respectively (P = 0.991), which was longer than that in test GCV group (8.6 ± 2.8 weeks) and there was a significant difference between test GCV group and negative control (placebo) group or positive control ACV group (P = 0.000). Furthermore, the recurrent rate was higher in negative control (placebo) group (47.3%) than that in positive control group ACV (26.7%) and test GCV group (17.2%), and there was a great significant difference among the three groups (P = 0.007), but there was no significant difference between positive control ACV group and test GCV group (P = 0.358). In addition, there was no obvious adverse reaction expect neutropenia (only one patient in test GCV group).

CONCLUSIONShort-term oral GCV could cure recurrent HSK and endotheliitis, shorten the course, reduce recurrent rate of HSK and have confirmed safety.

Objective:To investigate the efficacy and safety of anlotinib combined with whole brain radiation therapy in the treatment of driver gene mutation-negative non-small cell lung cancer (NSCLC) patients with multiple brain metastases.Methods:Forty-two driver gene mutation-negative NSCLC patients with multiple brain metastases who were admitted to Shaoxing People's Hospital from March 2018 to March 2022 were included. Among them, 21 patients in the anlotinib combined with whole brain radiation therapy group were enrolled from a prospective single-arm study (clinical trial registration number: ChiCTR1900027769), and the patients in the whole brain radiation therapy-alone group were enrolled from a concurrent retrospective study, and after 1∶1 propensity score matching, a total of 21 patients were finally included. The intracranial objective response rate (iORR), intracranial disease control rate (iDCR), intracranial progression-free survival (iPFS), overall survival (OS), and adverse events were compared between the two groups.Results:Among 21 patients in the arotinib combined with whole brain radiation therapy group, there were 1 case (4.8%) of complete remission (CR), 13 cases (61.9%) of partial remission (PR), 6 cases (28.6%) of stable disease (SD), and 1 case (4.8%) of progressive disease (PD). Among 21 patients in the whole brain radiation therapy-alone group, there were 0 case of CR, 10 cases (47.6%) of PR, 7 cases (33.3%) of SD, and 4 cases (19.0%) of PD. The iORR was 66.7% (14/21) and 47.6% (10/21) in the anlotinib combined with whole brain radiation therapy group and whole brain radiation therapy-alone group, respectively ( P = 0.212), and the iDCR was 95.2% (20/21) and 81.0% (17/21), respectively ( P = 0.343). The median iPFS time was 10.4 and 5.3 months in the anrotinib combined with whole brain radiation therapy group and the whole brain radiation therapy-alone group, respectively, and the difference in iPFS between the two groups was statistically significant ( P = 0.049); the 1-year OS rate was 50.5% and 39.5%, and the 2-year OS rate was 29.9% and 26.3%, respectively, with the median OS time of 13.4 and 6.6 months, respectively. The difference in OS between the two groups was not statistically significant ( P = 0.452). The most common treatment-related adverse effects in the anlotinib combined with whole brain radiation therapy group were loss of appetite (13/21, 61.9%), hypertension (11/21, 52.4%), fatigue (10/21, 47.6%), diarrhea (6/21, 28.6%), vomiting (6/21, 28.6%), dizziness (9/21, 42.9%), and headache (8/21, 38.1%). No ≥grade 4 adverse effects were observed, and there were no significant differences in adverse effects between the two groups (all P > 0.05). Conclusions:Anlotinib combined with whole brain radiation therapy can prolong the iPFS time of driver gene mutation-negative NSCLC patients with multiple brain metastases, and it is well-tolerated in terms of safety.

Objective To evaluate the differences of toxicities,therapeutic efficacy and immune function between induction chemotherapy followed by sinusoidal chrono-modulated infusion and flat intermittent infusion of cisplatin (DDP)with intensity-modulated radiotherapy (IMRT) in patients with locoregionally advanced nasopharyngeal carcinoma (NPC).Methods Seventy patients with biopsydiagnosed stages Ⅲ and Ⅳ B NPC (according to the 2010 UICC staging system) were treated with two-cycle induction chemotherapy before chemoradiotherapy in Guizhou Cancer Hospital.The TPF chemotherapy regimen was administered as follows:The TXT and DDP with the dose of 75 mg/m2 was carried out by bolus infusing for the first day,the 5-FU with 750 mg · m-2 · d-1 was carried out by continuous intravenous pumping for the first day to fifth day(120 h).The induction chemotherapy was 21 days per cycle,for two cycles.After that all patients were randomly treated with 2-3 cycles of sinusoidal chronomodulated infusion or flat intermittent constant rate infusion of DDP with IMRT.Using a multi-channel programmed pump,the patients were given 12 h continuous infusions of DDP (100 mg/m2) for day one,repeated every 3 weeks for 2-3 cycles.DDP was administered from 10:00 am to 10:00 pm.Concurrent radiotherapy regimen was administered as follows:GTVnx 69.96-73.92 Gy/33 f,PTVnx 69.96 Gy/33 f,PTVnd 69.96 Gy/33 f,PTV1 60.06 Gy/33 f,PTV2 50.96 Gy/28 f.Results The main toxicities of chemoradiotherapy in the group of sinusoidal chrono-modulated infusion were bone marrow suppression:leukocytes,and then nausea,oral mucositis and hemoglobin.The main toxicities of chemoradiotherapy in the group of flat intermittent constant rate infusion were bone marrow suppression:hemoglobin,leukocytes,and then nausea,oral mucositis.No significant differences were observed for toxicities(P ＞ 0.05).After concurrent chemoradiotherapy,the complete response rate (CR),partial response rate (PR),stable disease rate(SD),progressive disease rate (PD) and overall response rate (ORR) were 11.4％,85.7％,2.9％,0 and 97.1％ in the group of sinusoidal chrono-modulated infusion.The CR,PR,SD,PD,ORR in the group of flat intermittent constant rate infusion were 22.9％,74.2％,2.9％,0,97.1％,respectively.However,there was no significant differences of effect in the two Arms (P ＞ 0.05).For sinusoidal ehrono-modulated infusion and flat intermittent infusion group,the 2-year overall survival(OS) were 82.9％ and 94.3％ respectively,the 2-year progression-free survival(PFS) were 77.1％,91.4％ respectively,and the 2-year distant metastasis free survival (DMFS) were 82.9％,91.4％ respectively.The value of CD3 + in the group of sinusoidal chrono-modulated infusion was higher than the group of flat intermittent constant rate infusion after therapy (Z =3.254,P ＜ 0.05).The value of CD4 +,CD8 +,CD16 + CD56 +,CD19 +,and CD4 +/CD8 + had no differences in two Arms (P ＞ 0.05).Conclusions No significance differences on the toxicities,therapeutic efficacy and survival were observed between the two groups,but immune function might be improved in the sinusoidal chrono-modulated infusion group.
