Abstract
Objectives Postpartum hemorrhage (PPH) is a common cause of maternal death worldwide, but data on PPH incidence and influencing factors for nulliparous and multiparous women is scarce. So, the study aimed to assess the differences in PPH incidence and influencing factors between nulliparous and multiparous women. Methods A multicenter retrospective cohort study was conducted among women who gave birth at ≥ 28 weeks of gestation in Hunan Province, China, from January 2017 to December 2018. Logistic regression assessed PPH-influencing factors, and the receiver operating characteristic curve (ROC curve) assessed the predictive performance of identified factors. Results A total of 144,845 postpartum women were included in the study. The incidence of PPH (blood loss ≥ 500 ml) was 2.1 % and 1.7 % for nulliparous and multiparous women, respectively. Among the nulliparous and multiparous women, similar influencing factors of PPH included erythrocyte suspension transfusion before childbirth, anemia, soft-birth canal avulsion, Cesarean-section, placenta abruption, and general anesthesia administration before birth. Thrombophlebitis was associated [aOR 18.46(1.67-20.31)] with PPH among only the nulliparous women, while instrument-assisted birth [aOR 1.95(1.16-3.28)] and gestational hypertension [aOR 1.57(1.13-2.19)] were associated with PPH among only the multiparous women. The areas under the ROC-curve for the overall-cohort, nulliparous, and multiparous groups were [0.829(0.821-0.838)], [0.828(0.815-0.840)] and [0.833(0.822-0.844)], respectively. Conclusion PPH incidence is higher among nulliparous women than among multiparous women, but influencing factors vary relatively by parity. The study findings provide new insights into the use of different approaches to PPH prevention for nulliparous and multiparous women in clinical practice.

Abstract
Objective: To describe the situation and identify factors associated with malnutrition among infants and young children aged 6-23 months in poor rural areas in Hunan Province in 2015. Methods: 8 735 rural infants and young children aged 6-23 months in 30 poor counties of Wuling Mountains and Luoxiao Mountains in Hu'nan province were selected by township-level probability proportional to size sampling (PPS) in August 2015, infants' body length and weight were measured, and questionnaires were used to collect infants' information on personal and family, and feeding status in the past 24 h. The prevalence of stunting, underweight and wasting were calculated according to the Growth Standards of Child Aged Under 7 in China which was established in 2009 by Community Health Department of National Health and Family Planning Commission, China (formerly Chinese MOH), and the prevalence of malnutrition was calculated according to the classification of children with anthropometric failure. Multi non-conditional logistic regression model were used to analyze factors associated with malnutrition among infants and young children aged 6-23 months. Results: The prevalence of malnutrition among infants and young children aged 6-23 months was 13.7% (1 198/8 735), the prevalence of stunting, underweight and wasting among infants and young children aged 6-23 months were 4.8% (419/8 735), 9.7% (849/8 735) and 6.1% (531/8 735) respectively. Compared with male group, the OR value of malnutrition for the female group was 1.16; Compared with Han ethnic group, the OR value of malnutrition for the Miao and Tujia ethnic group were 0.83 and 0.66, respectively; Compared with mother with an education level of primary school or below, the OR value of malnutrition for the mother with junior high school, senior high school and university or above education were 0.65, 0.61 and 0.56, respectively; Compared with father with an education level of primary school or below, the OR value of malnutrition for the father with senior high school and university or above education were 0.71 and 0.61 respectively; Compared with normal birth weight group, the OR value of malnutrition for the low birth weight group and high birth weight group were 2.85 and 0.27 respectively; Compared with normal delivery group, the OR value of malnutrition for the premature delivery group was 1.37; all P values<0.05. Conclusion: The prevalence of malnutrition among infants and young children aged 6-23 months in poor rural areas in Hunan province in 2015 was high; Infants and young children who were female, Han ethnic, parents with low education, low birth weight and premature delivery had higher risk of malnutrition.

Abstract
Objective: To describe the status of, and to identify the factors associated with, complementary feeding among infants and young children aged 6- 23 months in poor rural areas of Hunan Province, China. Methods: A total of 8 735 infants and young children aged 6- 23 months from 30 poor rural counties in the Wuling and Luoxiao Mountains in Hunan Province were selected by township-level probability-proportional-to-size sampling in August 2015. Questionnaires were used to collect information on the feeding status of the infants in the previous 24 hours, along with personal/family information. The qualified rate of minimum dietary diversity (MDD), the minimum meal frequency (MMF) and the minimum acceptable diet (MAD) were calculated according to the WHO indicators for assessing infant and young child feeding practices. Multi non-conditional logistic regression models were used to analyze factors associated with complementary feeding among infants and young children aged 6- 23 months. Results: The findings indicated that 73.9% (6 452/8 735) of infants and young children aged 6-23 months received the minimum dietary diversity, 81.6% (7 124/8 735) of infants and young children aged 6- 23 months received the minimum meal frequency and 49.0% (4 276/8 735) of infants and young children aged 6- 23 months received an acceptable diet. Compared with the boys, the OR for the MMF and MAD for the girls were 1.15 and 1.11, respectively. Compared with the 6-11 month group, the OR for the MDD for the 12-17 month and 18-23 month groups were 0.41 and 0.38, respectively; the OR for the MMF for the 12-17 month and 18-23 month groups were 1.53 and 2.46, respectively; and the OR for the MAD for the 12-17 month and 18-23 month groups were 0.60 and 0.60, respectively. Compared with the Han ethnic group, the OR for the MDD, MMF and MAD for the Miao ethnic group were 1.43, 1.72 and 1.56, respectively; for the Tujia ethnic group were 2.21, 2.02 and 2.11, respectively; and for the Dong ethnic group were 0.62, 0.61 and 0.64, respectively. When analyzing data related to the children's mothers, compared with women who gestated at the age of 25- 29, the OR for the MMF for women who gestated at less than 20 years of age was 1.59 and at greater than or equal to 35 years of age was 1.33. Compared with women with primary school education or below, the OR for the MDD, MMF and MAD for women with junior high school education were 0.77, 0.74 and 0.80, respectively; for women with senior high school education were 0.67, 0.65 and 0.68, respectively; and for women educated to university level or above were 0.66, 0.47 and 0.60, respectively. Compared with the normal birth weight group, the OR for the MMF for the low birth weight group was 0.71, and for the high birth weight group was 1.30. Compared with the caregivers who provided qualified feeding knowledge, the OR for the MDD, MMF and MAD for the caregivers who provided unqualified feeding knowledge were 1.45, 1.30 and 1.40, respectively. Compared with the breastfed group, the OR for the MDD and the MMF for the non-breastfed group were 0.53 and 0.36, respectively. All P values were <0.05. Conclusion: Most infants and young children aged 6-23 months in poor rural areas of China met the MDD and MMF requirements, but fewer met the MAD requirements. The risk factors in infants and young children for complementary feeding included being of female gender, lower in age (months), of Miao or Tujia ethnicity, being born to a mother who gestated at less than 20 or ≥35 years of age, being born to a mother of low education, having a high birth weight, having a caregiver who provided unqualified feeding knowledge and being breastfed.

Abstract
OBJECTIVE To find out the cause and transmission factors of an outbreak of eosinophilic meningoradiculitis in Wenzhou City during October to November in 1997. METHODS In addition to a retrospective cohort study on 182 persons who had dined at a same restaurant of the city, etiological and immunoserological investigations were conducted. RESULTS Among 105 cases who had eaten the undercooked Ampullaria gigas in that restaurant, 47 cases were infected, the incidence rate was 44.8%; whereas none of the persons who did not eat the under-cooked Ampullaria gigas in that restaurant got the infection, the difference between the two groups being significant(P < 0.001). The incidence rate of the cases who had eaten 4 and more pieces of the undercooked Ampullaria gigas was 86.2%(25/29), while that of those who had eaten less than 4 pieces was 28.9%(22/76), the difference between the two being very significant (chi 2 = 27.83, P < 0.001, RR = 2.98). The third stage larvae of the Angiostrongylus cantonensis were found out from Ampullaria gigas living in the same locality, and the adult worms of Angiostrongylus contonensis were found out from the rats living in the locality else. The positive rate of serum anti-Angiostrongylus cantonensis antibody in the patients was 84.0%. CONCLUSION On the basis of the clinical, epidemiological, immunoserological and etiological investigations, an outbreak of the angiostrongyliasis cantonensis caused by eating undercooked Ampullaria gigas was confirmed.

Abstract
The influence of electroacupuncture (EA), a traditional Chinese medical treatment, on type II collagen-induced arthritis (CIA) was examined in DBA/IJ mice in vivo. Mice were immunized intradermally twice at a 3-week interval with bovine type II collagen (C II). EA stimulation, begun on day 21 simultaneously with the second immunization, was applied at the acupoint equivalent to GV4 three times a week for 3 weeks. The results showed that EA delayed the onset, attenuated the severity of arthritis, and reduced the anti-collagen antibody level. Furthermore, we investigated the impact of EA on the productions of endogenous interleukin-1 beta (IL-1 beta) and prostaglandin E2 (PGE2), and the levels of IL-1 beta mRNA in splenocytes and synovial tissues from C II immunized mice on day 45 and cyclooxygenase-2 (COX-2) mRNA in lipopolysaccharide (LPS)-stimulated macrophages of normal mice by using reverse transcriptase-polymerase chain reaction (RT-PCR). EA stimulation significantly inhibited the concentrations of splenic endogenous IL-1 beta and serum PGE2. The expression of IL-1 beta mRNA in spleen cells was obviously down-regulated and that in synovial tissues was modestly affected by EA. COX-2 mRNA was highly expressed in cultured peritoneal macrophages when stimulated with LPS. Previous treatment with EA also reduced LPS-stimulated induction of COX-2 mRNA. These data suggest that EA has an inhibitory effect on murine CIA, and the partial mechanism of its therapeutic result may be attributed to inhibiting the productions of IL-1 beta and PGE2 by suppressing the IL-beta and COX-2 gene activations.

Abstract
The present study was designed to investigate the antipyretic action of peripheral stimulation with electroacupuncture (EA) in SD rats. EA stimulation was applied for 30 min to the peripheral muscle where the equivalent Quchi (LI11) acupoint is located. We first examined the effects of EA stimulation on fever induced by either lipopolysaccharide (LPS), interleukin-1 beta (IL-1 beta) or prostaglandin E2 (PGE2). Intraperitoneal injection of LPS at a dose of 100 micrograms/kg caused a high rectal temperature, which was suppressed by EA stimulation. EA stimulation also inhibited the development of fever induced by IL-1 beta injection either intravenously or into the preoptic area (POA). The rats that received administration of PGE2 into POA developed rapid and high fevers, which were attenuated by EA stimulation. In the second part of the experiment, we investigated the levels of cytokines and PGE2 during the development of fever. The concentrations of IL-6 and PGE2 but not IL-1 beta, in brain and serum were increased by intraperitoneal injection of 100 micrograms/kg LPS. EA stimulation reduced PGE2 levels in both brain and serum in LPS-injected rats, but failed to change the levels of IL-6. Intravenous injection of IL-1 beta produced high brain and serum PGE2 levels, which were also significantly suppressed by EA stimulation. The results suggest that EA stimulation possesses an antipyretic effect through the inhibition of the action of PGE2 in rats.

Abstract
The influence of moxibustion, a traditional Chinese medical treatment; on type II collagen-induced arthritis (CIA) was examined in DBA/1J mice in vivo. Mice were immunized intradermally twice at 3-week intervals with bovine type II collagen (C II). The main incidence of arthritis started around day 30 and lasted to day 60 after the first immunization. Moxibustion, using three different regimens, was applied at the acupoint equivalent to GV4 every other day. Moxibustion, from day 0 to day 30 after the first immunization, suppressed the onset and development of arthritis, as well as anti-collagen antibody level. Treatment with moxibustion, from the day 31 to day 60, also resulted in a significant inhibition of progression of arthritis and production of anti-C II antibody. Furtherfore we examined the influence of moxibustion on the established arthritis. Moxibustion given from day 61 to day 120, mildly but significantly decreased the anti-C II antibody level in diseased mice, while the bone erosion and joint destruction were not affected. These results indicate that moxibustion could prevent the incidence and attenuates the development of murine CIA.

Abstract
AIM To study quantitatively the memory existing in ion channels. METHODS Stochastic processes were used to model 2 categories of memory (short-term and long-term) by persisting in the standpoint of two-state, instead of multiple states, but with different transition mechanism. RESULTS A two-state Markov process with constant transition intensities well fitted the short-term memory and a two-state Markov process within a kind of random environment well fitted the long-term memory. Statistical procedures for parameter estimation were proposed and demonstrated with 2 real examples on the channels of PC12 cells. CONCLUSION The memory in ion channels can be quantitatively modelled as stochastic process with 2 states.

Abstract
AIM To explore the existence of memory in Ca(2+)-dependent K+ channels of cultured aortic smooth muscle cells (ASMC) and voltage-dependent K+ channels of clonal pheochromocytoma (PC12) cells. METHODS Calculating the sample auto-correlation functions based on the digitized signals or the 0-1 series corresponding to closing and opening of the channels after routine evaluation, rather than the sequence of sojourn times. RESULTS The sample auto-correlations showed a decreasing trend with elapse of time, stable to repeated observations under the same conditions and sensitive to treatments. CONCLUSION The attribute of memory exists in some single channels as an intrinsic feature of them, independent of any extrinsic assumptions on missing observations due to limited time resolution.

Abstract
Through the treatment of 65 cases of painful diseases with electroacupuncture, in comparing with the analgesic effect of contralateral stimulation (CS) and ipsilateral stimulation (IS), it was verified that IS and CS had the similar effect on pain-relieving, while CS was better in improving motor impairment. By testing the rat's pain threshold and recording the neuronal activity in the D-PAG, it was found that neither IS nor CS could increase the pain threshold in the unilateral D-PAG lesioned rats, and the excited neuronal discharge was recorded in the unilateral D-PAG by stimulating rat's Zusanli (ST 36) at each side. It indicates that IS and CS might share the same high level afferent pathway in acupuncture analgesia in CNS.

Abstract
Clinical behavior of giant cell tumor of bone (GCT) may vary remarkably from latent to very aggressive. Quantitative pathological methods were used to evaluate the aggressiveness of GCT. Fifteen cytometric parameters were measured and computed on routine sections of 40 GCTs which had been treated with curettage. The surgery factor (with or without additional procedures like bone cement packing or freezing after the curettage) was also taken into account and computed. Nineteen of the 40 GCTs were cured and 21 recurred. While no single one from the 15 parameters measured showed significant differences between the cured and recurrent groups according to the Mann-Whitney's U test or Student's t test, a 4-variable function was established with a stepwise discriminant analysis which could correctly identify 70.8% of the predicted cases as cured or recurrent (jackknife procedure). The function also suggested that in addition to the surgery factor, which no doubt had close relation with the prognosis, the most important risk factor in histological parameters was SA40, i.e. the percent of cells with nucleus larger than 40 square microns. Single cells extracted from paraffin-embedded blocks of 38 GCTs were analyzed by DNA-image cytometry. The 2c deviation index (2cDI) showed wide heterogeneity ranging from those consistent with benign tumors to those with apparent malignant ones, which may account for its diversity in clinical behaviour. Sixteen of the 38 cases had been treated with curettage, 8 of them were cured and followed up for at least 3 years and the remaining 8 recurred. The significant difference of 2cDI between the two groups suggested that these DNA parameters are useful in evaluating the aggressiveness of GCT for the selection of an adequate treatment. Quantitative approaches appeared to be more objective and more sensitive in evaluating the aggressiveness and predicting the prognosis of GCT than the subjective grading system used before.

Abstract
This paper describes the results of some experiments on estimating the 3-D motion parameters of a rigid body from two consecutive TV images, and discusses several factors which affect the accuracy of the results. These factors include the sizes of the motion parameters themselves, the accuracy of the raw data, and the number of point correspondences. In addition, we address two related topics: determining corner positions to subpixel accuracy and matching point patterns with different scales.
