Abstract: Objective To analyze the epidemiological characteristics of 151 cases of melioidosis and the drug resistance of Burkholderia pseudomallei (BP), in order to provide the basis for diagnosis, treatment and reasonable prevention of melioidosis. Methods A total of 151 inpatients and outpatients from the Second Affiliated Hospital of Hainan Medical University from January 1, 2013 to August 31, 2022 were collected, and clinical specimens were submitted for examination to isolate and identify BP strains. The clinical data of 151cases of melioidosis and the drug resistance characteristics of pathogenic bacteria were retrospectively analyzed, and using SPSS26.0 software for statistical analysis. Results Among 151 cases with BP infection, there were 138 males (91.4%) and 13 females (8.6%); the most patients were aged from 45-<60 years old, accounting for 74 cases (49.0%); melioidosis incidence was concentrated in October (19.2%), November (19.2%), August (9.9%) and July (8.6%), and; the number of confirmed cases showed an increasing trend and the time for confirmation was <10 d; Internal medicine system (31.1%), surgery system (26.5%) and intensive care department (20.5%) were the common departments for treating melioidosis; blood (49.0%), sputum (9.9%) and wound secretion (8.6%) were the main clinical specimens for detecting BP; pulmonary infection (68.2%), sepsis (35.1%) and local suppurative infection (23.8%) were the top clinical manifestations in patients with BP infection; the effective rate of treating melioidosis was 74.8%; abnormal liver function was a risk factor for the curative effect of melioidosis (χ2=5.010, P<0.05); the sensitivity rates of BP strains to sulfamethoxazole-trimethoprim (SXT), doxycycline (DOX), imipenem(IPM), ceftazidime (CAZ), amoxicillin/clavulanate (AMC) and tetracycline (TCY) were generally more than 90%, with sensitivities of 98.7%, 97.2%, 96.7%, 94.0%, 93.2% and 90.7%, respectively. Conclusions It can be concluded that misdiagnosis or missed diagnosis of melioidosis is easy to occur, and the understanding of the epidemiological characteristics and risk factors in this area should be strengthened. The sensitivity of BP to commonly used antibiotics has shown a certain downward trend, clinical use should be standardized, and drug resistance monitoring should be strengthened to improve the efficacy of melioidosis treatment.

Chinese Acupuncture & Moxibustion 2007;27(3):213-216
Ideas of professor KONG Zhao-xia about acupuncture points were explained through the discussion of four aspects of meridian points and extra-ordinary points, confirmed points and non-confirmed points (Ashi points), located points and the area of points, the area of points and area of non-points. Acupoints are the special responsive spots of qi and blood on the body surface. All meridian points, confirmed points, extra-ordinary points, non-confirmed points possess peculiar functions, thus, more attention should be paid to selection and combination of points. The size of acupoint area, the therapeutic effects as well as acupuncture manipulation depend upon the location of acupoints. Acupuncture and moxibustion are two kinds of therapies, and both of them have own indications, so, you should attach same importance to the two therapies. Acupuncture and moxibustion are important therapeutic techniques and belong to external therapies. They could be applied alone, or be used in combination with Chinese herbal medicine according to conditions of the patient.

Chinese Journal of Integrated Traditional and Western Medicine 2007;27(8):739-742
OBJECTIVETo compare the clinical efficacy of Chinese traditional herbs (CTH) alone or combined with Western medicine (conventional treatment plus different doses of prednisone) in treating anaphylactic purpura nephritis (APN).
METHODSClinical data of 232 patients with APN were collected and analyzed. They were assigned to four groups. Patients in Group A1 were treated with CTH; in Group A2 were treated initially with Western medicine but turned midway to CTH; in Group B1 and B2 treated with CTH combined with conventional Western medicine and plus low or high dose of prednisone respectively. The comprehensive clinical efficacy on symptoms, physical signs, routine urine examination, blood creatinine and urea nitrogen, as well as the treatment duration and long-term effect in the four groups were observed.
RESULTSThere was no significant difference in the comprehensive clinical effects among the four groups (P > 0.05). However, the treatment duration was significantly shorter in Group A1 and B1 than in the other two groups (P < 0.01). Follow-up study on patients in similar duration showed similar reoccurrence rate among groups (P > 0.05).
CONCLUSIONChinese herbs has definite effects on APN with the treatment course shorter than that of other treatments, the optimal protocol for treatment of APN is applying Chinese herbs alone or combined with conventional Western medicine plus low dose prednisone. It is necessary to conduct a follow-up study even though the patients have been cured.

OBJECTIVETo discuss the relations of dental fluorosis and the social economic status in fluorosis-stricken villages where drying the corn by burning coal was prevail.
METHODSA total of 6 fluorosis-endemic villages and one non-endemic village were involved in the study. The general fluorine intake and the concentrations of fluorine in corn, in the pupils' were tested. Dental fluorosis among the pupils was also examen. A individual interview or household questionnaire survey was conducted to probe the economic condition and staple food structure in 600 adults.
RESULTSThe fluorosis prevalence was lower in the villages of transportation convenience, higher income, less coal-dried corn intake. There was a declining trend of dental fluorosis in the corresponding age groups (r: 0.912, 0.916; P < 0.05); There was no significant changes in age-specified dental fluorosis in the low income villages. The correlation (r) of corn fluorine concentration and student's age-specified dental fluorosis prevalence and disparity was 0.755 - 0.980 (P < 0.05) and 0.302 - 0.811; The urine fluorine concentrations were 0.811 and 0.915 (P < 0.05). It was assumed that there was a negative correlation between family cash income and the dental fluorosis.
CONCLUSIONSThe corn fluorine concentration is closely related to age-specified dental fluorosis. With the economic improvement, taking less coal-burned corn is the one of major factors in reducing the of dental fluorosis in these areas.

OBJECTIVETo investigate the correlation of serum sex hormones and parathyroid hormone (PTH) with the biochemical markers of bone turnover in aged men.
METHODSWe collected the laboratory data of 465 men aged 60- 93 (73. 1 +/- 8. 3) years old, who came for routine physical examinations in our hospital. We obtained the levels of serum follicle- stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), testosterone (T), sex hormone binding globulin (SHBG), PTH, 25-hydroxy-vitamin D3 (25(OH) D3), and bone turnover markers C-terminal telopeptide of type I collagen (CTX), osteocalcin (OC) and amino-terminal propeptide of type I procollagen (PINP). We also determined free testosterone (FT) , bioactive testosterone (BT) , testosterone secretion index (TSI) and FT index (FTI), and analyzed the correlation of each index with the biochemical markers of bone turnover.
RESULTSThe concentrations of serum FSH, LH, and SHBG increased, while the levels of FT, BT, TSI, FTI, PTH, CTX, OC and PINP decreased with age, especially in those over 80 years old (P <0.05). PTH was positively correlated with CTX, OC and PINP (r =0. 227, 0. 269 and 0. 162, P <0. 01), even after the adjustment for age, while SHBG negatively correlated with OC (r = -0. 100, P <0.05). The bone turnover markers increased with the elevation of the PTH quartiles, with significant differences between the first and the fourth quartile (P <0. 01). Multiple stepwise regression analysis showed that age was correlated inversely with CTX, OC and PINP ( beta = -0. 126, -0. 141 and -0. 122, P <0.05) , PTH positively with the three markers (beta = 0. 196, 0.279 and 0.189; P <0. 001), and SHBG negatively with OC ( beta = -0. 100, P <0.05) .
CONCLUSIONAging is the fundamental cause of reduced bone turnover in aged men. The levels serum PTH and SHBG are significantly associated with the biochemical markers of bone turnover.

Objective To investigate the value of permeability surface (PS) in predicting hemorrhagic transformation (HT) in acute ischernic stroke (AIS) using CT peffusion (CTP).Methods The study included 31 consecutive patients who presented symptoms suggestive of an AIS for 3-9 h. All patients underwent CT examination (noncontrast CT,CTP).HT was determined by follow-up CT images.According to presence of HT,the AIS was divided into HT group (PSHT,11 patients) and non-HT group(PSNo-HT,20 patients).PS,cerebral blood flow (CBF),cerebral blood volume (CBV) and mean transit time (MTT) on both sides of brains were measured.The relative PS(rPS),relative CBF (rCBF),relative CBV(rCBV) and relative MTT(rMTT) were obtained by calculating the ratio of the values of bilateral regions.The rPS between PSHT and PSNo-HT was compared with an exact Wilcoxon signed-rank test. The rCBF,rCBV,rMTT and the PS of the ischemic side between PSHr and PSNo-HT were compared with independent-sample t test.Meanwhile,Spearman rank correlation analysis was conducted to analyze the relationship between the CTP parameters and HT.ResultsThe PS value of ischemic side was (1.61±0.77) ml · min - 1 · 100 g-1 for the PSHT group,and the value was (0.91 ± 0.49) ml · min - 1 · 100 g- 1 for the PSNo-HT group.For the PSHT group,rPS,rCBF,rCBV,rMTT were 2.76 ±0.78,0.32 ±0.18,0.66 ±0.31,2.67 ±0.71,and for the PSNo-HT group,rPS,rCBF,rCBV,rMTT were 1.35 ±0.19,0.50±0.21,0.91 ±0.28,2.62 ± 1.31.Compared with PSNo-HT,PSHT had higher rPS and PS value,and there were significant statistical differences (U =0.000,t =3.070,P <0.01).But rCBF and rCBV values were lower in the PSHT group compared to the PSNo-HT group,and there were significant statistical differences (trCsF =2.343,trCBV =2.210,P < 0.05).There was no significant statistical difference in rMTT between the two groups(t =0.118,P > 0.05).Significant positive correlations were detected between the rPS and PS with HT(r=0.496,0.821,P <0.01).ConclusionsThe value of rPS is helpful in predicting HT in AIS.And it can be used as a predictor in determining clinical personalized treatment and thus reduce the incidence of adverse events.

Objective To explore the current status of the prenatal care quality and the influencing factors in Hangzhou City. Methods We used sociodemographic characteristics questionnaire and the Chinese version of QPCQ to investigate 383 pregnancy women who were at 36 weeks' gestation or greater by convenient sampling method from September to December in 2016. Results A total of 350 questionnaires were valid. The average age of 350 samples was (29.71±3.67) years old. There were 231 primiparas which accounted for 66.00%. Among them, 196 (56.00%) were satisfied with the prenatal care they received, and 153 (43.70%) think general, and only 1 (0.30%) felt unsatisfied. The score of the Chinese version of QPCQ was 3.61±0.50. The item "My prenatal care professional (s) always answered my questions honestly" had the highest scores of 4.10±0.62, while "My prenatal care professional (s) did things hastily" had the lowest scores of 2.44±0.96 . By multiple linear regression analysis, those people who had more visiting time (β' = 0.21, P<0.01), less waiting time (β' = -0.18, P<0.01) and the cognition of the essentiality of pregnancy school (β' = 0.12, P=0.02) were more likely to give higher regards for the quality of prenatal care. Conclusion Sufficient time scored relative lower in the whole questionnaire. So, hospitals could take efforts to shorten the waiting time by promoting the hospital process optimization, making good use of this period time and other strategies, so as to improve the quality of prenatal care.
