OBJECTIVETo observe the effect of Schistosoma japonicum cysteine protease inhibitor (rSjCystatin) for treatment of lipopolysaccharide (LPS)-induced sepsis in mice.

METHODSAfter a week of adaptive feeding, 54 BALB/c mice were randomly divided into normal control group (group A), sepsis group (group B), and rSjCystatin intervention group (group C). The mice in group A received an intraperitoneal injection of PBS (100 µL), and those in groups B and C were injected with PBS (100 µL) containing LPS (10 mg/kg); the mice in group C were also intraperitoneally injected with 25 µg sjCystatin in 100 µL PBS 30 min after LPS injection. From each group, 10 mice were randomly selected 24 h after PBS or LPS injection for detecting serum levels of TNF-α, IL-6, and IL-10 using ELISA and the levels of ALT, AST, BUN, and Cr using automatic biochemical analyzer; the pathological changes in the liver, lung and kidney were observed with HE staining. The remaining 8 mice in each group were used for observing the changes in the general condition and the 72-h survival.

RESULTSThe 72-h survival rates of the mice was 100% in group A, 0 in group B, and 36% in group C, showing a significant difference among the 3 groups (P<0.05). Compared with those in group A, the mice in group B exhibited obvious liver, lung, and renal pathologies with increased levels of ALT, AST, BUN, Cr, IL-6, and TNF-α (P<0.05). Treatment with sjCystatin significantly lessened LPS-induced organ pathologies, lowered the levels of liver and renal functional indexes and the pro-inflammatory cytokines, and increased the serum level of IL-10 in the mice (P<0.05).

CONCLUSIONSjCystatin can produce a significant therapeutic effect on sepsis induced by LPS in mice.

OBJECTIVETo investigate the status of the clinical agency of detection, management, and health insurance for hypertensive patients in urban and rural communities of five provinces in China in 2010, in order to provide fundamental data for implementation and evaluation of community health management of hypertensive patients in basic public health service.

METHODSFrom Jiangsu, Shandong, Hebei, Sichuan and Gansu provinces, cities and districts (counties) were selected according to economic development level and 10 survey sites were finally determined. In each survey site, 3-4 communities or townships were selected by cluster sampling methods in 2010. A total of 8326 eligible hypertensive patients (4363 in urban and 3963 in rural) were included. The urban-rural difference of clinical agency and health insurance was compared for hypertensive patients.

RESULTSIn urban areas, 43.74% (1867/4268) hypertensive patients were first diagnosed at hospitals of district level or above, 25.07% (1070/4268) at community health service centers (CHSC), and 20.20% (862/4268) at community health service stations (CHSS), respectively; 30.72% (1274/4147) and 31.11% (1290/4147) patients chose CHSC and CHSS for their follow-up visiting, respectively; 60.23% (3073/5102) antihypertensive medication was obtained from pharmacies. In rural areas, 54.58% (2133/3908) hypertensive patients were first diagnosed at village clinics, 22.36% (874/3908) at township hospitals, and 18.86% (737/3908) at hospitals of county level or above; 70.49% (2695/3823) patients chose village clinics for their follow-up visiting; 46.23% (2116/4577) antihypertensive medication was obtained from village clinics, and 36.29% (1661/4577) from pharmacies. The main reasons for choosing clinical agency for both urban and rural patients were convenience (45.79%, 6276/13 706) and low cost (11.78%, 1614/13 706). The proportions of reimbursements for hospitalization expenses and total medical expenses for hypertensive patients in urban in the past year were 66.67% and 34.78%, respectively, which were much higher than those in rural (35.71% and 9.50%) (Z value was -12.13 and -17.56, P < 0.01).

CONCLUSIONCommunity-based hypertension detection and routine blood pressure measurement during clinical visiting should be further strengthened to improve early diagnosis of hypertension. The development of community-based clinical agency should be able to provide convenient and low cost health service for hypertensive patients to improve treatment, follow-up and control of hypertension.

OBJECTIVETo investigate the current situation of drug cost, hospitalization cost and direct medical expense in community health management of hypertensive patients, in order to lay foundation for evaluating whether the community health management in basic public health service has cost-effect in Health Economics.

METHODSA total of 8326 hypertensive patients from 10 survey pilots in 5 provinces were selected by cluster sampling methods, including 3967 patients who took part in community health management for over 1 year as management group and 4359 cases who have never taken part in community health management as control group. The essential information of research objects were collected by questionnaire; and the medical cost information in the last year (from November 2009 to November 2010) were collected retrospectively. The different annual medical treatment cost, hospitalization cost and direct medical expense in the two groups were compared and analyzed.

RESULTSThe average annual drug cost in hypertension was (621.50 ± 1337.78) yuan per patient; while the cost was (616.13 ± 1248.40) yuan in management group and (626.44 ± 1414.30) yuan in control group respectively. The average annual drug cost of hypertensive patients who took medicine therapy was (702.05 ± 1401.79) yuan per person, while the cost in the management group ((688.50 ± 1300.70) yuan) was much lower than it in control group ((714.64 ± 1489.60) yuan). The annual average drug cost in urban was (731.88 ± 1403.31) yuan per person, which was higher than it in rural as (407.44 ± 1171.44) yuan per person. The average hospitalized rate was 12.2% (1014/8326), and the average annual cost among the hospitalized patients was (9264.47 ± 18 088.49) yuan per person; while the cost was (7583.70 ± 13 267.00) yuan in management group, which was lower than it in control group as (11 028.00 ± 21 919.00) yuan. The average annual hospitalized cost in hypertension was (1064.87 ± 6804.83) yuan per person; while the cost was (936.73 ± 5284.90) yuan in management group, which was lower than it in control group as (1181.50 ± 7937.90) yuan. The average annual direct medical expense in hypertension was (2275.08 ± 8225.66) yuan per person; while the expense was (2165.10 ± 6564.60) yuan in management group and (2375.20 ± 9487.60) yuan in control group. The average annual direct medical expense in urban ((2801.06 ± 9428.54) yuan per person) was higher than it in rural ((1254.70 ± 4990.27) yuan per person).

CONCLUSIONThe community health or standardized management of hypertensive patients can reduce the average annual drug cost and hospitalization cost (around 26 yuan and 245 yuan separately); and thereby save the annual direct medical expense per capita in hypertension (around 210 yuan). In the reform and development of national medical health system, we should enhance and promote the standardized community health management of hypertensive patients.

For qualitative and quantitative analysis of related substances in clotrimazole cream, HPLC-Q-TOF spectrometer was used to analyze the fragmentation pathways and identify structures of the related substances. Five related substances named by BP (2018) were identified as impurity A ((2-chlorophenyl)-diphenylmethanol), impurity B (para-clotrimazole isomer), impurity E (2-chlorobenzophenone), impurity F (1-tritylimidazole) and impurity 4 (9-(2-chlorophenyl)-fluorene), respectively, by using impurity references matching and comparison with the literature data. Four related substances were detected in clotrimazole cream except impurity E, and 9-(2-chlorophenyl)-fluorene is the first identified impurity in this preparation. To establish an HPLC method for determination of the related substances in Clotrimazole Cream, the Agilent Poroshell Bonuns RP column was used (100 mm×4.6 mm, 2.7 μm) with UV detection at 215 nm. The mobile phase was acetonitrile-10 mmol·L^-1 dipotassium phosphate buffer (adjusted with phosphoric acid to pH of 5.80) with a flow rate of 1.0 mL·min^-1. Gradient elution was used. The column temperature was maintained at 40℃. A good linear behavior was achieved between component's concentrations and peak area for impurity A, B, E, F within the range of 0.20-10.02 μg·mL^-1, 0.20-10.00 μg·mL^-1, 0.20-10.10 μg·mL^-1, 0.10-5.01 μg·mL^-1 with the correlation coefficients were 0.999 7, 1.000 0, 1.000 0, 0.999 9, respectively. The average recoveries were 94.3%, 95.0%, 100.0%, 99.6% with RSDs were 2.8%, 2.2%, 1.1%, 2.7%, respectively (n=9). LOQ were 200.4, 200.0, 202.0, 100.2 ng·mL^-1, respectively. LOD were 57.25, 57.14, 57.71, 28.63 ng·mL^-1, respectively. The developed method was simple, rapid, accurate and effective for testing related substances in clotrimazole cream to control its quality, ensuring the safety of clinical medication.

Prolactinoma is an estrogen-related tumor and leukemia-related protein 16 (LRP16) is correlated with the progression of estrogen-related tumors, but the regulatory mechanism between LRP16 and prolactinoma remain unclear. This study demonstrates a variation in LRP16 with estrogen receptor α (ERα) in prolactinoma models and the up and downregulation effects of LRP16 on prolactin secretion of pituitary adenomas cells (GH3 cells). In our study, 50 male SD rats (30-day-old) were randomly divided into five groups of 10 rats each. After 120 days of treatment, the rats were sacrificed, and the expression of LRP16 and ERα were examined by Western blot and immunohistochemistry to explore the changes in ERα, LRP16, and prolactin. After siRNA transfection of the respective genes, the GH3 cells were cultured, and their secretory function as well as the expression of ERα mRNA and prolactin were analyzed by enzyme-linked immunosorbent assay and real-time-polymerase chain reaction analysis. The results show that secretion of prolactin by GH3 cells can be affected by up and downregulating LRP16 expression, which may provide a novel medical therapy in clinical trials.

Decoction is the most commonly used dosage form in the clinical treatment of traditional Chinese medicine (TCM). During boiling, the violent movement of various active ingredients in TCM creates molecular forces such as hydrogen bonding, π-π stacking, hydrophobic interactions and electrostatic interactions, which results in the formation of self-assembled aggregates in decoction (SADs), including particles, gels, fibers, etc. It was found that SADs widely existed in decoction with biological activities superior to both effective monomers and their physical mixtures, providing a new idea to reveal the pharmacodynamic material basis of Chinese herbal medicine from the perspective of component interactions-phase structure. Recently, SADs have become a novel focus of research in TCM. This paper reviewed their relevant studies in recent years and found some issues to be concerned in the research, such as the polydispersity of decoction system, instability of active ingredient interactions during boiling, uncertainty of the aggregates self-assembly rules, and stability, purity, yield of the products. In this regard, some solutions and new ideas were presented for the integrated development and clinical application of SADs.

BACKGROUNDGlobally, the proportion of child deaths that occur in the neonatal period remains a high level of 37-41%. Differences of cause in neonate death exist in different regions as well as in different economic development countries. The specific aim of this study was to investigate the causes, characteristics, and differences of death in neonates during hospitalization in the tertiary Neonatal Intensive Care Unit (NICU) of China.

METHODSAll the dead neonates admitted to 26 NICUs were included between January l, 2011, and December 31, 2011. All the data were collected retrospectively from clinical records by a designed questionnaire. Data collected from each NICU were delivered to the leading institution where the results were analyzed.

RESULTSA total of 744 newborns died during the 1-year survey, accounting for 1.2% of all the neonates admitted to 26 NICUs and 37.6% of all the deaths in children under 5 years of age in these hospitals. Preterm neonate death accounted for 59.3% of all the death. The leading causes of death in preterm and term infants were pulmonary disease and infection, respectively. In early neonate period, pulmonary diseases (56.5%) occupied the largest proportion of preterm deaths while infection (27%) and neurologic diseases (22%) were the two main causes of term deaths. In late neonate period, infection was the leading cause of both preterm and term neonate deaths. About two-thirds of neonate death occurred after medical care withdrawal. Of the cases who might survive if receiving continuing treatment, parents' concern about the long-term outcomes was the main reason of medical care withdrawal.

CONCLUSIONSNeonate death still accounts for a high proportion of all the deaths in children under 5 years of age. Our study showed the majority of neonate death occurred in preterm infants. Cause of death varied with the age of death and gestational age. Accurate and prompt evaluation of the long-term outcomes should be carried out to guide the critical decision.
