[Objective]Microsurgical lumbar discectomy(MSLD)and microendoscopic discoectomy(MED)were compared in methods and curative effect for providing the experience and therapy evidence of lumbar disc herniation(LDH).[Method]It was retrospectively analyzed that mono-segment lumbar disc herniation were treated in minimal invasion in our hospital.MSLD was 45 cases and MED was 32 cases.Operation time,operation information,complication,hospital time and curative effect were compared.[Result]The satisfactory rate of two groups were both beyond 90% and no significant deviation was found.The incision of MED was obviously shorter than MSLD and the operation time of MED was longer than latter.[Conclusion]The curative effects of two minimal invasion methods are satisfactory.But the indication of MED is limited obviously and the method has not obvious predominance by compared with MSLD.MSLD is an more ideal minimal invasion operation at present.

Objective To investigate MR imaging features of femoral marrow in treated ?-thalassemia major.Methods MR imaging of the proximal femoral marrow was performed in 35 cases of ?-thalassemia major and 45 age-and sex-matched normal children as control.Coronal images of femoral marrow with the techniques of spin echo and fast field echo(FFE)were obtained.On T_1-weighted imaging the red and yellow femoral marrow were judged and marrow distribution was classified into five groups.The hemosiderosis of marrow was judged on the basis of signal intensity of marrow on FFE imaging.The marrow distribution classification and the hemosiderosis on MR imaging were correlated with clinical features.Results On FFE,marrow hemosiderosis occurred in 15 patients with a marked hypo-intensity signal and was related to the age(P=0.032).On T_1-weighted imaging,the femoral marrow in 35 patients was classified as groupⅢand IV,while the marrow distribution was groupⅠorⅡin all normal children,there was statistically significant difference(P

AIM To explore the curative effects,adverse events,effects on immunity function and cost-effectiveness of Aiyu Capsules (Cremastrae pseudobulbus,Solanum lyratum,Angelicae sinensis Radix,etc.) or Fufang Banmao Capsules (Mylabris,Ginseng Radix et Rhizoma,Astragali Radix,etc.) combined with icotinib hydrochloride in the treatment of advanced non-small cell lung carcinoma (NSCLC).METHODS One hundred and sixty patients with advanced NSCLC were randomly divided into three groups.The patients in icotinib hydrochloride group (n =80) took icotinib hydrochloride,125 mg each time,three times a day;the patients in Aiyu Capsules + icotinib hydrochloride group or Fufang Banmao Capsules + icotinib hydrochloride group were treated with Aiyu Capsules (40 cases,three pills each time,three times a day) or Fufang Banmao Capsules (40 cases,one pill each time,three times a day) combined with icotinib hydrochloride (125 mg each time,three times a day),respectively.Curative effects,adverse events,serum tumor markers,dendritic cell subsets and cost-effectiveness among the three groups were compared.RESULTS Eight weeks after the treatment,effective rates in the Aiyu Capsules + icotinib hydrochloride group (82.50％) and Fufang Banmao Capsules + icotinib hydrochloride group (97.5％) were significantly higher than that in the icotinib hydrochloride group (73.5％) (P ＜ 0.05).Six-month survival rates in the icotinib hydrochloride group,Aiyu Capsules + icotinib hydrochloride group and Fufang Banmao Capsules + icotinib hydrochloride group were 93.7％,97.5％ and 97.5％,respectively;one-year survival rates in the three groups were 53.7％,72.5％ and 75.0％,respectively;two-year survival rates in the three groups were 20.0％,37.5％ and 40.0％,respectively.One-year,two-year survival rates in the Aiyu Capsules + icotinib hydrochloride group and Fufang Banmao Capsules + icotinib hydrochloride group were significantly higher than those in the icotinib hydrochloride group (P ＜ 0.05).Myeloid dendritic cell (mDC) subsets' increases (d8week-d1) in the Aiyu Capsules + icotinib hydrochloride group and Fufang Banmao Capsules + icotinib hydrochloride group were significantly higher than that in the icotinib hydrochloride group (P ＜ 0.05).There was no statistical significance in plasmacytoid dendritic cell (pDC) subsets' change among the three groups (P ＞ 0.05).Changes of carcinoembryonic antigen (CEA),cytokeratin-19-fragment (CYFRA21-1),neuron-specific enolase (NSE) in the Aiyu Capsules + icotinib hydrochloride group and Fufang Banmao Capsules + icotinib hydrochloride group were higher than those in the icotinib hydrochloride group (P ＜ 0.05).Treatment costs in the Aiyu Capsules + icotinib hydrochloride group and Fufang Banmao Capsules + icotinib hydrochloride group were significantly lower than that in the icotinib hydrochloride group (P ＜ 0.05).No obvious statistical difference in adverse events was found among the three groups (P ＞ 0.05).CONCLUSION The curative effects and cost-effectiveness of Aiyu Capsules or Fufang Banmao Capsules combined with icotinib hydrochloride are better than those of icotinib hydrochloride alone in the treatment of advanced NSCLC.

OBJECTIVEThis study aimed at exploring the feasibility of using dried blood spots (DBS) to detect HIV drug resistance genotyping in China by comparing the results of drug resistance from DBS, plasma and whole blood samples.

METHODSBlood samples were collected from 39 AIDS patients from Anhui (10), Yunnan (13), Hunan (6) and Xinjiang (10) provinces and autonomous regions. The HIV strains that infected these patients covered all the major HIV-1 subtypes prevailing in China (B, CRF01_AE, CRF07_BC). HIV drug resistance genotyping assay was performed on DBS as well as on the whole blood and plasma samples from the same patients simultaneously by using an in-house nest RT-PCR method. Drug resistance levels were determined based on Stanford University HIV drug resistance database, and the results from these three types of samples were compared.

RESULTSThe percentages of successful amplification of protease and reverse transcriptase regions in the pol gene were 95% (37/39) from DBS, 92% (36/39) from whole blood and 100% (39/39) from plasma samples. The sequences from the three types of samples showed more than 99% identity.86% (31/36) of the DBS samples had the same set of drug resistance mutations as those which were detected from plasma samples. The differences probably resulted from mixed bases.

CONCLUSIONSThere was no major difference in detecting HIV drug resistance genotyping among DBS, plasma and whole blood samples. Therefore, DBS is useful for detection of HIV drug resistance genotyping and is particularly valuable in developing countries like China, especially in remote rural regions.

OBJECTIVETo identify genetic variation of HIV-1 predominant subtype B and C strains in China during rapid horizontal transmission and to elucidate the potential relationship between genetic variation and selective pressure.

METHODSAfter the fragments of HIV-1 env gene were amplified by nested-PCR from the whole blood of 258 HIV-1 infected individuals, PCR products were directly sequenced using ABI 377 DNA sequencer. The sequences covering env V3-V4 region of 72 HIV-1 subtype B(n=37) and C(n=35) strains were selected for phylogenetic analysis. In addition, the ratios of synonymous (Ks) substitutions per nonsynonymous (Ka) substitutions were calculated using DIVERGE.

RESULTSThe genetic distances of the V3-V4 region of subtype B strains were higher than that of subtype C strains. Furthermore, sequence analysis revealed that the V4 region was more variable than the V3 region for both subtype B and C strains. What's more, the V3 loop was less variable compared with the V3 upstream region and C3 region for subtype C Ks/Ka ratios of the entire aligned sequence of the two subtypes were below 1 0, with the lowest values found in the V3 region of subtype B strain and the V4 region of subtype C strain.

CONCLUSIONSThe majority of variation in both subtypes B and C strains occurred in the V4 rather than the V3 region. It is important that our study found for the first time the V3 loop was more conservative than the V3 upstream region and C3 region for subtype C. Calculations of the Ks/Ka ratios throughout the V3-V4 region demonstrate that significant selective pressures experienced during the rapid horizontal spread of the virus in the Chinese HIV-1 infected population may have directed change in the V3 loop for the subtype B strain and the V4 loop for the subtype C strain. These results will contribute to the policy of AIDS prevention and control and the ongoing development vaccine.

BACKGROUNDSeverity scoring systems are useful tools for measuring the severity of the disease and its outcome. This pilot study was to verify and compare the prognostic performance of the Simplified Acute Physiology Score II (SAPS II) and Glasgow Coma Scale (GCS) in neuro-intensive care unit (N-ICU) patients.

METHODSA total of 1684 patients consecutively admitted to the N-ICU at Xuanwu Hospital between January 1, 2005 and December 31, 2011 were enrolled in this study. The data-base included admission data, at 24-, 48-, and 72-hour SAPS II and GCS. Repeated measure data analysis of variance, Logistic regression analysis, the Hosmer-Lemeshow goodness-of-fit statistic, and the area under the receiver operating characteristic were used to evaluate the performance.

RESULTSThere was a significant difference between the SAPS II or GCS score at four time points (F = 16.110, P = 0.000 or F = 8.108, P = 0.000). The SAPS II scores or GCS score at four time points interacted with the outcomes with significant difference (F = 116.771, P = 0.000 or F = 65.316, P = 0.000). Calibration of the SAPS II or GCS score at each time point on all patients was good. The percentage of a risk estimate prediction corresponding to observed mortality was also good. The 72-hour score have the greatest consistency. Discriminations of the SAPS II or GCS score at each time were all satisfactory. The 72-hour score had the greatest discriminative power. The cut-off value was 33 (sensitivity of 85.2% and specificity of 74.3%) and 6 (sensitivity of 70.6% and specificity of 65.0%). The SAPS II at each time point on all patients showed better calibration, consistency and discrimination than GCS. The binary Logistic regression analysis identified physiological variables, GCS, age, and disease category as significant independent risk factors of death. After the two variables including underlying disease and type of admission were excluded, we built the simplified SAPS II model. A correlation was suggested between the simplified SAPS II score at each time point and outcome, regardless of the diagnosis.

CONCLUSIONSThe GCS scoring system tends to be a little weaker in the predictive power than the SAPS II scoring system in this Chinese cohort of N-ICU patients. The advantage of SAPS II scoring system still exists that it dose not need to take into account the diagnosis or diseases categories, even in the special N-ICU. The simplified SAPS II scoring system is considered a new idea for the estimation of effectiveness.

Objective:To evaluate delayed laparoscopic cholecystectomy (DLC) after percutaneous transhepatic gallbladder drainage (PTGBD) in acute cholecystitis.Methods:Clinical data of 64 patients who were diagnosed moderate (grade Ⅱ) acute cholecystitis by the 2018 Tokyo Guidelines in acute phase and underwent delayed LC at our hospital from Jan 2018 to Jan 2021 were compared between two groups ie PTGBD treatment (21 cases)in acute stage before DLC and DLC without PTGBD group (43 cases). The difficulty score of TG18 was used to evaluated every surgical procedure of the cases by reviewing the operation videos.Results:Patients in DLC after PTGBD group had a longer hospital stay and operation time, more blood lose and higher difficulty score than the DLC without PTGBD group(all P<0.05). There was no statistically significant difference in the conversion rate and morbidity rate between the two groups( P>0.05). Conclusion:This study fails to show there is any if ever benefit of PTGBD before DLC over DLC without PTGBD in the management of Grade Ⅱ acute cholecystitis.

To evaluate the effect of Naoshuantong capsule on the life quality of patients with ischemic stroke in six months of follow-up studies, and observe the adverse events. The results would provide reference for the secondary prevention on the recovery stage of ischemic stroke. 696 patients from 12 Class III Grade I hospitals nationwide were divided into 2 groups by central randomization system. The study group, 344 cases, were treated with Naoshuantong capsule plus Aspirin, and the control group, 352 cases, were treated with Aspirin. The patients were treated for 6 months. At the end of treatment, SS-QOL used for evaluating the quality of life was observed. The safety index was defined by adverse observation event. The incidence of adverse events and laboratory tests results were observed before and after treatment at the same time. The results indicated that compared to the control group, the treatment group had significant statistical difference in the impact of effort, self-care ability and the the work or labor ability of patients (P < 0.05). No serious adverse events were observed. Naoshuantong capsule showed some superiority to Asprin on improving the quality of life on patients with ischemic stroke, and it could be used in secondary prevention on the recovery stage of ischemic stroke. Naoshuantong capsule is safe and effective in the treatment of convalescence ischemic stroke.
