Objective To study the epidemiology of mycoplasma pneumonia (MP) infection in children and its relationship to meteorological conditions in Guilin. Methods Total of 1 342 hospitalized children with respiratory tract infections from Janu-ary 2011 to December 2012 were recruited, and the serum levels of mycoplasma pneumoniae antibody Ig (MP-Ig) were measured. Meanwhile, monthly meteorological conditions were collected. The relationships between the MP-Ig detection rates and meteoro-logical conditions were analyzed by multiple linear regression analysis. Results The total detection rate of MP-Ig was 23.2%with positive rates as 5.51%, 28.99%, 37.31%and 44.97%for 0-1, 1-3, 3-6 and>6 year-old groups respectively (P<0.01). The positive rate of female was higher than that of male with signiifcant difference (30.08%vs 19.05%, P<0.01). The positive rate of spring, summer, autumn and winter were 18.89%, 17.39%, 23.83%and 33.05%individually (P<0.01). Negative correlation was found be-tween detection rate of MP-Ig and monthly mean air temperature (P=0.001). Conclusion MP is one of the commonest pathogens of respiratory tract infection in children and mostly seen in elder female children with a higher incidence in winter. The main me-teorological factor is the low temperature that affects MP prevalence.

In the present study, we first report the seroprevalence of Dirofilaria immitis in dogs in Shenyang, northeastern China. Sera from 528 randomly selected dogs were examined for D. immitis antigen using SNAP(R)4Dx test kit; 12.7% tested showed seropositive. No significant difference of infection was observed in different genders and breeds (P>0.05), but the difference was significant in different age groups and rearing conditions (P<0.05). The result suggested that the risk of exposure to D. immitis in dogs is high in Shenyang, and should be given attention.

OBJECTIVETo explore the association of fish intake with the risk of renal cancer.

METHODSPubMed, Embase, CNKI and CA databases were searched for case-control studies or cohort studies examining the relationship between fish or fish products intake and renal cancer. Heterogeneity among the selected studies was assessed using I2 score, and the publication bias was assessed using funnel plots.

RESULTSSeventeen articles were included in the analysis with a heterogeneity across the studies (P=0.003, I(2)=52.3%). A random-effects model was used to generate the pooled risk ratio (RR) and 95% confidence interval (CI), and no statistically significant association was found between the risk of renal cancer and fish intake (RR=0.90; 95% CI, 0.78-1.02). In subgroup analysis, no evidence was found that the study design, study region or publication date influenced the results; but in the gender subgroup analysis, fish intake we found to decrease the risk of renal cancer in men but not in women.

CONCLUSIONThe results of meta-analysis do not support an association between fish intake and a lowered risk of renal cancer.

Filamentous microalga Tribonema sp. has the advantages of highly resistance to zooplankton-predation, easy harvesting, and high cellular lipid content, in particular large amounts of palmitoleic acid (PA) and eicosapentaenoic acid (EPA). Therefore, Tribonema sp. is considered as a promising biomass feedstock to produce biodiesel and high-value products. In this work, we studied the effect of different concentrations of nitrogen (NaNO₃: 255-3 060 mg/L), phosphorus (K₂HPO₄: 4-240 mg/L), iron ((NH₄)₃FeC₁₂H₁₀O₁₄: 0.6-12 mg/L) and magnesium (MgSO₄: 7.5-450 mg/L) on the biomass, lipid content, and fatty acid composition of Tribonema sp. FACHB-1786, aiming at enhancing cell lipid productivity. The growth of Tribonema sp. had a positive correlation with the concentration of magnesium, and the maximum biomass of Tribonema sp. (under the condition of 450 mg/L MgSO₄) was 8.09 g/L, much greater than those reported in previous studies using the same and other Tribonema species under autotrophic conditions. Different nitrogen concentrations exerted no significant effect on algal growth (P > 0.05), but a higher nitrogen concentration resulted in a greater amount of lipid in the cells. The maximum volumetric productivities of total lipids (319. 6 mg/(L·d)), palmitoleic acid (135.7 mg/(L·d)), and eicosapentaenoic acid (24.2 mg/(L·d)) of Tribonema sp. were obtained when the concentrations of NaNO₃, K₂HPO₄, (NH₄)₃FeC₁₂H₁₀O₁₄, and MgSO₄ were 765 mg/L, 80 mg/L, 6 mg/L, and 75 mg/L, respectively. This study will provide a reference for substrate optimization for Tribonema sp. growth and lipid production.

ObjectiveTo observe the effect of warming needle moxibustion based on rehabilitation on rotator cuff injury. MethodsFrom January, 2019 to January, 2020, 70 patients with rotator cuff injury from Rehabilitation Hospital, Fujian University of Traditional Chinese Medicine were randomly divided into control group (n = 35) and experimental group (n = 35). Both groups received Mulligan mobilization and rotator cuff muscle group muscle energy technique (MET) training, while the experimental group received warming needle moxibustion at Jianyu (LI15), Jügu (LI16), Jianqian and Jianzhen (SI9) in addition, for two weeks. They were assessed with Shoulder Pain and Disability Index (SPADI), Visual Analogue Scale for pain (VAS), range of motion of shoulder (ROM), and shoulder isokinetic muscle strength before and after treatment, and the complications and recurrence were observed. ResultsThere were five cases in the control group and four cases in the experimental group dropped. The SPADI score, VAS score decreased (|t| > 5.039, P < 0.001), and the ROM and R value of isokinetic muscle strength testing increased (|t| > 2.751, P < 0.01) in both groups after treatment, while the SPADI score, VAS score were less (|t| > 3.616, P < 0.001); the ROM, and R values of isokinetic muscle strength testing of flexion, extension, adduction and abduction were more (|t| > 2.214, P < 0.05) in the experimental group than in the control group. ConclusionWarming needle moxibustion can further relieve shoulder pain in patients with rotator cuff injury, and improve shoulder ROM, muscle strength and functioning.
