Objective To investigate the inhibitory effect of Pingliukang (a prescription) medicated serum on the proliferation of cultured rat C6 glioma cells and influence on cell cycle in vitro. Methods MTT colorimetry were performed to measure the levels of the proliferation of rat C6 glioma cells cultured with 2.5%, 5%, 10% and 20% of Pingliukang medicated serum for 24 h, 48 h and 72 h in vitro. The effect of Pingliukang medicated serum on cell cycle were observed by FCM. Results The proliferation of C6 cell was obviously inhibited by Pingliukang medicated serum with dose-effect relationship. The inhibitory effect of 20% of medicated serum was the strongest. When the C6 glioma cells were treated with 10% and 20% medicated serum for 48 h and 72 h, the cells of S period declined. Conclusion The Pingliukang medicated serum can inhibit the proliferation and block cell cycle of cultured C6 glioma cells.

Objective: To explore the application of extensive pterional approach combined with cutting of the zygomatic arch for the resection of large sphenoid ridge meningioma. Methods: Thirty-three patients with large sphenoid ridge meningioma underwent operation using the extensive pterional approach combined with cutting of the zygomatic arch. Twenty patients with large sphenoid ridge meningioma received operation with the traditional pterional approach as the control. The resection rate, operative time, intraoperative blood loss, and postoperative complications were compared between the groups. Results: Two groups of patients underwent craniotomy under microscope. The Simpon grade I resection and grade Ⅱ resection rate was 93.9％ in the cutting of the zygomatic arch approach group and 60.0％ in the control group (P<0.01). The operative time was (325.2±121.3) min in the cutting of the zygomatic arch approach group, which was significantly shorter than that in the control group with (406.4±182.9) min (P<0.05). The intraoperative blood loss was (502.5±101.8) mL and (697.7±115.4) mL in the two groups (P<0.05). In addition, postoperative complication rate was 15.2％ and 45.0％ in the cutting the zygomatic arch approach group and the control group, respectively (P<0.05). No death was reported in both groups. Conclusion: Extensive pterional approach combined with cutting of the zygomatic arch can fully expose the anatomical structures of the skull base and the sellar region to eliminate the influence of temporal muscle in the exposure of the surgical area. The operative field is exposed to reduce the stretch injury to only the frontotemporal brain tissue, which might be helpful for the complete resection of large sphenoid ridge meningioma, and is more conducive to neurovascular anatomy and relevant functional protection.

Objective To study cost-effectiveness of primary cerebral infarction patients. Methods The neural function of primary cerebral infarction patients was studied by the National Institutes of Health Stroke Scale (NIHSS) with rank test and multiple regression analysis. Results After treatment in hospitals of different grades, no obvious difference was detected in the NIHSS score, but difference was found in therapy cost and therapy time; the NIHSS score and therapy time of primary cerebral infarction patients in different attack positions were obviously different, but therapy cost had no significant statistical difference. The NIHSS score of primary cerebral infarction patients with different treatments was obviously different, but therapy cost and therapy time was not. Conclusions Patients are advised to choose grade hospitals in nearby cities for treatment. Clinician are expected to choose low-cost treatment plan to relieve patients' economic burden.

Objective To investigate the effect of tramadol on the expression of 5-HT1A receptor in the distal'cerebrospinal fluid contacting neurons (CSF-CNs) in mid-brain in a rat model of neuropathic pain. Methods Forty male SPF SD rats weighing 220-280 g were randomly divided into 5 groups (n = 8 each): group Ⅰ normal control (group C); group Ⅱ normal saline (group NS); group Ⅲ tramodol (group T); group Ⅳ neuropathic pain + normal saline (group NP+ NS) and group Ⅴ neuropathic pain + tramadol (group NP + T). Neuropathic pain was induced by chronic constrictive injury (CCI) in group Ⅳ and Ⅴ . Four silk ligatures were placed on the sciatic nerve at 1 mm intervals. In group Ⅱ (NS) and group Ⅲ (T) the sciatic nerve was exposed but not ligated and NS 2 ml/kg and tramadol 10 mg/kg were injected IP respectively, while in group Ⅳ and Ⅴ NS 2 ml/kg and tramadol 10 mg/kg were injected IP respectively on the 7th day after CCI. Paw withdrawal threshold (PWT) to von Frey filament stimulation and paw withdrawal latency (PWL) to noxious thermal stimuli were measured before (T1) and after IP NS or tramadol injection (T2) in group Ⅱ-Ⅴ. The distal CSF-CNs in the mid-brain was labelled with 30% cholera toxin subunit B and horseradish peroxidase compound (CB-HRP) 3 μl injected in left lateral cerebral ventricle. The expression of 5-HT1A receptors was measured by immuno-histochemistry. Results PWT and PWL were significantly decreased after CCI in group Ⅳ (NP + NS) and tramadol significantly inhibited the mechanical and thermal hyperalgesia in group Ⅴ (NP + T). There was no significant difference in the number of distal CSF-CNs among the 5 groups. CCI significantly down-regulated the expression of 5-HT1A in distal CSF-CNs in group Ⅳ(NP+ NS) as compared with group Ⅰ , Ⅱ and Ⅲ and tramadol significantly inhibited the CCI-induced downregulation of 5-HT1A receptor expression. Conclusion Tramadol can ease neuropathic pain by down-regulating the expression of 5-HT1A receptor in distal CSF-CNs in mid-brain.

Objective To investigate the clinical efficacy of ultrasound-guided and nerve stimu-lator-guided modified fascia iliaca compartment block combined with popliteal fossa sciatic nerve block in patients undergoing unilateral great saphenous varicose veins surgery.Methods Sixty patients, male 32 and female 28,aged 42-76 years,ASA Ⅰor Ⅱ,scheduled for unilateral great saphenous var-icose veins surgery were randomly divided into two groups (n =30 each):modified fascia iliaca com-partment block with popliteal fossa sciatic nerve block group(group N)and epidural anesthesia(group E).Firstly,popliteal fossa sciatic nerve block was performed in group N.Then confirmed iliac fascia and femoral nerve position on the ultrasonic image and the femoral nerve was blocked.The 1% lido-caine 10 milliliters and 0.5% ropivacaine 10 milliliters were injected in the fascia iliaca compartment block from medial border of sartorius to upward site of femoral artery.Meanwhile,the ultrasonic probe was moving inside in the level of inguinal ligament.The SBP,DBP and HR were recorded be-fore block(T0 ),10(T1 ),30(T2 )and 60 minutes(T3 )after block.The block working time and onset time of sensory block,use of ephedrine after anesthesia,anesthesia efficacy and the postoperative ad-verse reactions in the last 48 hours ,including nausea,vomiting,headache and urinary retention, were also recorded.Results Compared with T0 ,the SBP and DBP was significantly decreased at T2 in group E(P <0.05).Compared with group E at the same time,the SBP and DBP was significantly higher at T2 in group N(P <0.05).The onset time of sensory block was significantly shortened and the use of ephedrine after anesthesia was also less in group N(P <0.05 ).Group E was better than group N in the whole anesthesia efficacy (P <0.05),but there was no significant difference in the ex-cellent rate of anesthesia efficacy between the two groups.The incidence of postoperative urinary re-tention was significantly decreased in group N(P <0.05)and there was no significant difference of the rate of nausea,vomiting and headache.Conclusion Modified fascia iliaca compartment block with popliteal fossa sciatic nerve block has excellent anesthetic quality in patients undergoing unilateral great saphenous varicose veins surgery,which ensures more stable hemodynamics less side effects and more indications when compared with epidural anesthesia.
