The paper is to systematically evaluate the effect and safety of Shenqi Fuzheng injection (SFI) combined with first-line chemotherapy for non-small cell lung cancer (NSCLC). Randomized controlled trials (RCTs) on Shenqi Fuzheng injection (SFI) combined with first-line chemotherapy (experiment group) and chemotherapy alone group ( control group) were electronically retrieved from Medline, EMbase, Clinical Trials, Cochrane Library, CBM, CNKI, VIP, and Wanfang Data base. All trials were assessed for quality according to the Cochrane Reviewer's Handbook for Systematic Reviews of Intervention and then Meta-analysis was performed withRevMan5. 2 Software. A total of 43 RCTs (3433 patients) were included after screening and selecting. Results of Meta-analysis showed that: Objective remission rate (ORR): ORR of experimental group was about 20% higher than that of control group [RR = 1.23, 95% CI (1.11,1.35), P < 0.0001]. Disease control rate (DCR):DCR of SFI combined with first-line chemotherapy was 11% higher than that of first-line chemotherapy alone [RR = 1.11, 95% CI (1.07, 1.16), P < 0.000 01]. Life quality evaluated by Kosovan performance status (KPS) showed that: life quality improvement rate of experimental group was about twice of that in control group [RR = 2.02, 95% CI (1.81, 2.26), P < 0.000 01]. Toxic and side reaction analysis showed that: the incidence of side reactions in experimental group was about 50% lower than that in control group [RR = 0.59, 95% CI (0.53, 0.66), P < 0.000 01]. Immune function test showed that: the function of experimental group was 3.2 (standard deviations) times greater than that of control group [MD = 3.23, 95% CI (2.86, 3.60), P < 0.000 01]. We can see that SFI combined with first-line chemotherapy for NSCLC can increase objective efficacy, improve life quality, decrease toxic and side reactionsinduced by chemotherapy, and improve the immune functions. As most of the included studies in this systematic evaluation had poor quality, the evidence to support conclusion was weak, so it was necessary to conduct more multi-center clinical trials with high quality methods and rigorous design.

Objective To investigate the characteristics of grafts after reconstruction of ACL with autogenous bone-patellar tendon-bone(B-PT-B)grafts. Methods Reconstruction of anterior cruciate ligament with free B-PT-B autograft fixed with interference screw was performed on 39 adult dogs. Mechanical testing was conducted on the grafts by translating the tibia anteriorly with the knee in 90 degrees of flexion, until complete failure. Failure site, cross sectional area, strength, stiffness and stress were documented. After decalcification and HE staining, the transformation of the intra-tunnel and intra-articular ligaments was evaluated, and the histological observation was conducted for the healing in the bone-tunnel, patellar tendon-tunnel and bone-patellar tendon interface. Results Union occurred in the bone-tunnel interface at 4th week. The patellar tendon-tunnel interface was linked by Sharpey's like fibers at 52nd week, the cement line and the tendency of chondrocyte lining were found. Mechanical testing of graft revealed that the rupture always occurred at mid-portion of ligaments instead of pulling-out from the tunnel under tension stress. Compared with the control group, the strength, stiffness and stress of the graft were 38%, 58% and 50% of normal anterior cruciate ligament at 52nd week respectively. Conclusion The union in the bone-tunnel interface occurs at 4th week, much earlier than the healing of the patellar tendon-tunnel interface. The healing of the tendon to tunnel presents to be indirect insertion at 52nd week with alignment of chondrocytes, which signifies the still ongoing of healing process at the interface. After fixation with interference screw for 4 weeks, the tendon proved to be the weakest part in bone-tendon-bone complex. No need to worry about the biomechanical character of the new insertion site during rehabilitation activities. The attachment fixed by interference screw is stable not only immediately after surgery but also during the healing of the insertion and the transformation of ligament. One year after reconstruction, the mechanical quality of the grafted tendon still remains inferior to that of normal anterior cruciate ligament in spite of similar histological structure. Protective device should be recommended during active activity.

Objective To explore clinical effect of modified postural drainage for treating pulmonary infection of senile patients with gastric cancer.Methods 107 cases of patients with gastric cancer were randomly divided into two groups:control group (n =53) and treatment group (n =54),which were respectively treated by routine postoperative therapy and nursing measures and modified postural drainage based on these routine measures,and compared daily amount of expectoration sputum,positive cases of sputum culture,restore time of postoperative blood test,postoperative fever time,cases of pulmonary infection on the postoperative tenth day and length of stay.Results Daily amount of expectoration sputum of patients in treatment group was significantly higher than that of control group [(185.7 ± 23.7) ml vs.(99.7 ± 17.6) ml] (P ＜ 0.05).However,restore time of postoperative characters of blood test [white blood cell count (2.9±0.9) d vs (5.0±0.7)d,C-reaction protein (35±0.7)d vs.(7.4±0.6) d],postoperative fever time [(1.9±0.5) d vs.(3.6±1.4) d],cases of atelectasis (5 cases vs.19 cases) and length of stay [(1.9±0.5) d vs.(3.6±1.4) d] were respectively significantly less than those of control group (P ＜ 0.05).Conclusions Modified postural drainage could effectively prevent postoperative atelectasis and pulmonary infection,significantly reduced incidence of postoperative atelectasis of senile patients with gastric cancer operation,and so it was worthy of clinical application.

Objective: To evaluated the granules stabilities in four conditions by taking the change of Baricalin content and granules surface color as stability test markers. Methods: The content of baicalin was determined by dual wave length iso absortion method and the granules surface color was determined by the diffuse reflectrance spectroscopy. ① The granules were tested in a simulated summer environment (30 ?C , RH92.5%, 1month) and in a high intensity light condition (3000LX, 10dyas). ② The influence of humidity on the stability of the granules was investigated. ③ The expiry date of the granules was predicted by the mutivariate linear regression analysis and compared with the result of the classical constant temperature method. ④ The influences of temperature and humidity on the granules stability were etudied by orthogonal test. Results: ① There was hardly any change in baicalin content of samples in a simulated summer environment and in a high intensity light condition. ② The results showed that the decrease of baicalin content and charge of granules color were obvious when the relative humidity of environment was high and the granules color was more easily influenced by the humidity. ③ The expiry date was about 2.87 years. ④ The results indicated that both temperature and humidity had effects on the change of baicalin content. Conclusion: We tried to estimate the stability of the granules by two indexes. The results showed that Qingrejedu granules was stable in different conditions. It satisfied the stability requirements of solid dosage form.

Objective:To discuss the result of treating valgus or varus knee deformity with fixator assist nailing (FAN)technique and distal femur osteotomy(DFO).Methods:In this retrospective study,14 patients with 17 limbs,12 valgus and 5 varus knee deformity were treated with DFO and FAN.The aver-age age of the patients was 23 (17-44)years .The unilateral external fixator was mounted on the lateral side of femur,the minimal invasive distal femoral osteotomy was performed.After the deformity was cor-rected,the intramedully nail was inserted to fix the femur.None of the patients need bone autograft.The preoperation and postoperation lateral distal femur angle (LDFA ),mechanical axis deviation (MAD ) and range of motion (ROM)were measured and analyzed.Results:All the 14 patients were followed-up for 12 -72 months (average 34 months).The osteotomy site united in 3 -5 months (average 3.5 months)post-operatively.According to Paley’s functional scores,12 patients were excellent,2 patients were good.We achieved desired postoperative MAD (from medial 15 mm to lateral 10 mm)in 15 limbs of 12 patients.The LDFA in 1 1 limbs was corrected to normal (84°-90°).The ROM was not signifi-cantly changed before and after operation in the both groups.No infection or neuro-vascular injury oc-curred.Conclusion:The FAN technique is an effective method to treat valgus knee or varus knee de-formity in young patients with DFO.

ObjectiveTo evaluate the effectiveness of correction of posttraumatic flexion contracture of knee(FCK) using Ilizarov technique.MethodsSix male patients with posttraumatic FCK,aging from 9 to 43 years(mean,24.5 years),treated by using Ilizarov technique from January 2006 to December 2010,were retrospectively analyzed.The preoperative flexion deformity of knee ranged from 35° to 85° (mean,47.6°),and the range of motion ranged from 0° to 70° (mean,15.8°).Among them,five patients had old fracture of knee joint combined with equinus foot deformity (deformity ranging from 25° to 37°,with an average of 31.8°); one patient had femoral supracondylar fracture.We used circular external fixator to correct the FCK and equinus foot deformity gradually,the knee arthrodesis operation was performed in 4 patients because of the damaged hone structure and poor soft tissue condition.ResultsAll patients were followed up for 12-22 months(mean,18 months).The flexion of knee joint was recoverd from preoperative 47.67°±18.63° to postoperative 9.33°±3.50°.Plantar flexion of ankle joint in five equinus foot deformity was recovered from preoperative 31.80°±4.65° to postoperative 3.00°±4.47°.The kuee joint was arthrodesised successfully in 4 patients and the other 2 patients got 30° and 75° ROM.All the patients can walk with a cane,and satisfied with the result of treatment.Pin-site infection was found in 4 patients and was controlled within two weeks.ConclusionIlizarov technique is an effective treatment method for posttraumatic FCK.Knee arthrodesis should be performed when patients had damaged bone structure and poor soft tissue condition.

Objective To analyse the differential expression of miRNAs in the brain of offsprings of hypothyroid and normal rats,and to explore the molecular mechanism underlying the effect of hypothyroidism on brain development in the offspring.Methods Forty-eight female Wistar rats were assigned to (1) control group (n =24),and (2) hypothyroid group after complete thyroidectomy (n =24).Serum TSH and Total thyroxine (T4) were measured one month after the surgery.Brain samples of fetal or postnatal rats were obtained during four different developmental stages:embryonic days (E) 13,E17,postnatal days (P) 0 and P7.The hippocampus and cortex were separated on P7.MiRNAs were isolated from tissues and two samples were used at each time point studied to reduce the influence of individual differences.The brain samples were detected by Gene Chip miRNA arrays (Affymetrix).Results In the brain tissues of fetal or neonatal rats of maternal hypothyroid rats,two miRNAs (mir-206,-324-5p) on E13,three miRNAs (mir-34c,-204,-194) in cortex on P7,and five miRNAs (mir-146b,-532-5p,-384-5p,-215,-212) in hippocampus on P7 were up-regulated by over 2 folds.Five miRNAs (mir-200b,-200c,-217,-672,-139-5p) on E17,one miRNA (mir-376-3p) on P0,and four miRNA (mir-672,-204,-335,-376-3p) in hippocampus on P7 were decreased by 50％ or more.Conclusion The miRNA expression profiles in the rat brain of offspring with maternal hypothyroidism are characterized by miRNA arrays.The identification of a subset of brain expressed miRNAs in the brain may explain the brain development abnormalities resulting from maternal hypothyroidism.

Background The integration of segregated pathways from the two eyes first appears in V1 neurons,where it not only plays a critical role in the generation of a three-dimensional visual representation.Abnormal visual experiences in critical period usually lead to amblyopia and binocular integration defects.Objective Present study was to investigate how neurons of kitten coordinate their activity patterns in response to synchronous dichoptic stimulus inputs in striate cortex.Methods Spike rate and local field potential(LFP) gamma band(20-90Hz) power of three kitten(1-1.2Kg,8-10 weeks old) to monocular and synchronous dichoptic presented gratings were assessed for 28 binocular neurons in V1 of kitten by in vivo extracellular record method under anaesthesia and paralysis.Ocular dominance index(ODI) and binocular integration index(BII) were assessed and the correlation between these two indexes were analyzed.Results In 28 cells with binocular characteristic,the absolute value of spike-ODI was significant larger than that of LFP-ODI(t=2.606,P=0.021).A positive linear correlation between the ocular preferences of spike and LFP was found(R2=0.513,F=27.423,P=0.003).In dichotic trails,binocular facilitation with BII for spike was 2.348±0.996,showing a significant reduce in comparison with BII for LFP(3.678±1.974)(t=2.671,P=0.019).Binocular integration index for two signals were greater when monocular responses of both eyes were similar(P=0.035 and P=0.124,respectively).Conclusion Both spike rate and gamma band power of LFP exhibited binocular facilitation to synchronous presented dichotic stimuli with significant facilitation induced by balanced monocular responses.Spiking activity and LFP reflect neural activities of different spatial scales and source components.

This study evaluated the cytotoxicity of a new type silicone rubber for maxillofacial prosthesis, which was developed by the present authors. According to the GB/T16886. 5- 2003, the samples were prepared and tested with cell counting kit-8 (CCK-8) assay, the relative growth rate (RGR) was calculated, and morphology of L929 cells were observed by scanning electron microscope and phase contrast microscope. The results showed that RGR of L929 cells were 91.65% (24 h), 87.03% (48 h), 87.30% (72 h), respectively, and the level of cytotoxicity was grade 1. The L929 cells showed typical fusiform shape and their morphology did not changed significantly after 24 h, 48 h and 72 h. These data indicated that the newly-developed silicone rubber material, as a maxillofacial prosthesis material, should be a safe biomaterial.
