OBJECTIVETo explore the risk factors of low back pain (LBP) among greenhouse vegetable planting farmers and estimate the level of the effects.

METHODSA self-made questionnaire based on the Dutch Musculoskeletal Questionnaire and the Nordic Questionnaire was conducted to 639 greenhouse vegetable planting farmers and then structural equation model was used to analyze the risk factors of LBP in SmartPLS software.

RESULTSThe coefficient of determination of the model was 0.827, and the structural coefficients of dynamic loads, static loads, force exertion, ergonomic environment and repetitive loads on LBP were 0.21, 0.43,0.27, 0.045 and 0.034 respectively, and the total effects of the above latent variables on LBP were 0.21, 0.43,0.27, 0.33 and 0.034 respectively.

CONCLUSIONThe main risk factors of LBP among greenhouse vegetable planting farmers were static loads, ergonomic environment, force exertion and dynamic loads.

AIM: To evaluate the changes of corneal high - order aberration (including Coma, Spab, RMSh) after laser in situ keratomileusis (LASIK) with femtosecond laser, sub- Bowman keratomileusis ( SBK ) and laser epithelial keratomileusis (LASEK). METHODS: Of 82 myopic patients ( 164 eyes ), 31 patients (62 eyes) were treated by FS-LASIK, 31 patients (62 eyes) were treated by SBK, 20 patients (40 eyes) were treated by LASEK. Sirius system was used for measuring the coma aberration, spherical aberration, and high order aberration at 1, 15d,1, 3mo after surgery. RESULTS: 1) Vision: The uncorrected visual acuity of the three groups had no differences (P>0. 05). 2) Corneal aberrations: Three kinds of surgical procedure for patients with corneal aberration had significant impact. The C7, C8, C12 and RMSh of three groups were increased significantly (P<0. 05). The C7, C8, C12 and RMSh were not recovered to preoperative levels after 3mo. But the increase of patients after FS- LASIK was smaller than the other two groups, with statistical significance (P<0. 05). CONCLUSION: Compared with SBK and LASEK, FS - LASIK has better visual acuity in the early postoperative and corneal higher-order aberrations increase is relatively small.

Objective To study the expression of KAI1 and CD40 in gastric cancer and their correlation with clinicopathologic features and prognosis.Methods The expression of KAI1 and CD40 of 64 gastric cancer tissues was examinated by S-P immunohistochemieal methods.Results The overall positive rate of KAI1 was 22% in gastric cancer.Expression of KAI1 was positively related to the degree of tumor differentiation,it was negatively related to invasion depth and lymph node metastasis and the tumor clinical stage.The 5-year survival rate of cases with positive expression of KAII was significantly higher than that of cases with negative expression(X~2=42.426,P=0.000).The expression rate of CD40 in gastric cancer tissue was 34%.The expression of CD40 was significantly correlated with metastasis and clinical stage of gastric cancer.The 5-year survival rate of cases with positive expression of CD40 was significantly lower than that of cases with negative expression(X~2=4.841,P=0.028).There is no relationship between KAI1 and CD40 expression in gastric cancer.Conclusion KAI1 is associated with gastric cancer differentiation,invasion and metastasis.CD40 status helps to evaluate metastasis,and predict prognosis of gastric cancer.

So far there exists no corresponding quality test procedures and grading standards for the seed of Prunus humilis, which is one of the important source of base of semen pruni. Therefor we set up test procedures that are adapt to characteristics of the P. humilis seed through the study of the test of sampling, seed purity, thousand-grain weight, seed moisture, seed viability and germination percentage. 50 cases of seed specimens of P. humilis tested. The related data were analyzed by cluster analysis. Through this research, the seed quality test procedure was developed, and the seed quality grading standard was formulated. The seed quality of each grade should meet the following requirements: for first grade seeds, germination percentage ≥ 68%, thousand-grain weight 383 g, purity ≥ 93%, seed moisture ≤ 5%; for second grade seeds, germination percentage ≥ 26%, thousand-grain weight ≥ 266 g, purity ≥ 73%, seed moisture ≤9%; for third grade seeds, germination percentage ≥ 10%, purity ≥ 50%, thousand-grain weight ≥ 08 g, seed moisture ≤ 13%.

Objective To explore the efficacy,safety and life quality of patients of morphine hydrochloride sustained-release tablets combined with celecoxib in the treatment of advanced lung cancer with moderate to severe cancer-induced pain.Methods A total of 247 patients of advanced lung cancer with moderate to severe cancer-induced pain were randomly divided into combination therapy group (n =127) and morphine monotherapy group (n =120) using simple random sampling digital table method.The differences of dose,efficacy,adverse drug reactions and life quality between the two groups were analyzed.Results In achieving similar analgesic effect,the average maintenance dose of morphine in combination therapy group was (52.51 ±19.92)mg/d,lower than that in monotherapy group [(58.75 ±20.64)mg/d,t =-2.414,P =0.017].The incidence of constipation in combination therapy group was 34.6％,lower than that in monotherapy treatment group (47.5 ％,x2 =4.218,P =0.040).The life quality of the two groups were improved,and the life quality improvement rate in combination therapy group was 59.8％,higher than that in monotherapy treatment group (43.3％,x2 =6.736,P =0.009).Conclusion Morphine hydrochloride sustained-release tablets combined with celecoxib is effective in the treatment of moderate to severe cancer pain,which can reduce the dosage of morphine and reduce adverse reaction,so as to improve the life quality of the patients with advanced lung cancer.

Objective To study the role of serum Hcy level change in predicting the effects of pemetrexed (PEM ) chemotherapy for treating the patients with advanced lung adenocarcinoma .Methods Fifty‐seven cases of lung adenocarcinoma treated by the PEM chemotherapy were retrospectively analyzed .The fasting venous blood was collected for detecting serum Hcy level before chemotherapy and at the end of 2‐week chemotherapy .The clinical characteristics ,Hcy level before and after chemotherapy and the relation between the Hcy level with clinical effect were statistically analyzed .Results In the therapeutic effects evaluated by the im‐aging examination during treatment process ,there were no case of complete remission (CR) ,19 cases of partial remission (PR) ,22 cases of stable diseases(SD) and 16 cases of progressed diseases(PD) ,the objective response rate(ORR) was 33 .3% and disease control rate (DCR) was 71 .9% .Different clinical factors had no significant influence on the efficacy of PEM chemotherapy (P>0 .05) .In comparing the influence of Hcy level and Hcy level change on the effect of PEM chemotherapy ,the results showed that serum Hcy level before treatment had no obvious influence on curative effect ,DCR in the patients with normal serum Hcy level after treatment was significant higher than that with abnormal Hcy level ,ORR and DCR in the patients with decreased Hcy level after chemotherapy were significantly higher than those with increased Hcy level (P<0 .05) .Conclusion Monitoring the serum Hcy lev‐el change during the PEM chemotherapeutic process in the patients with advanced lung adenocarcinoma may be used in the predic‐tion of the chemotherapeutic effect .
