OBJECTIVETo study the therapeutic effect and feasibility of rectoclysis with Tuihuang decoction (RTD) in treating hyperbilirubinemia of newborns.

METHODSOne hundred and seventy-five newborns with hyperbilirubinemia were randomly divided into the treated group and the control group. They were treated with western medicine plus double faced blue treatment while the treated group were given RTD additionally. Blood bilirubin was detected by micro-bilirubin detector daily during the treatment course. The time of jaundice regression, the speed of blood bilirubin reducing, liver function, and condition of rebounding were observed.

RESULTSThe 7-day curative rate of jaundice in the treated group was superior to that in the control group, showing significant difference (P < 0.05). The average speed of blood bilirubin reducing daily in the treated group was quicker than that in the control group (P < 0.01). The improvement of liver function, such as AST, ALT and gamma-GT in the treated group was superior to that in the control group (P < 0.01). Rebound rate of blood bilirubin in the control group was significantly higher than that in the treated group (P < 0.05).

CONCLUSIONRTD is an ideal therapy for treatment of hyperbilirubinemia of newborn, it shows obvious clinical efficacy and can effectively prevent the rebound of blood bilirubin.

Objective:To observe the effect of electroacupuncture (EA) at Jiaji (EX-B 2) points plus hydro-acupuncture with sinomenine hydrochloride for low back pain caused by compression fractures in the elderly.Methods:Ninety-five elderly in-patients with low back pain caused by compression fractures were randomly divided into an observation group and an EA group according to the visit sequence.Both groups received the same basic treatment.In the EA group,48 cases were treated with EA at Jiaji (EX-B 2) points plus the basic therapy;47 cases in the observation group received the basic treatment plus EA and hydro-acupuncture with sinomenine hydroch｜oride at Jiaji (EX-B 2) points.The levels of osteoprotegerin (OPG) and interleukin-1β (IL-1β) in peripheral blood were measured by enzyme-linked immunosorbent assay (ELISA) before and at the 21st day of treatment in both groups.Oswestry disability index (ODI) and visual analog scale (VAS) scores were used to analyze the clinical efficacy.Results:After treatment,the OPG content in the observation group was higher with statistical significance compared with that before treatment in the observation group and after the treatment in the EA group,respectively (both P＜0.05);the content of IL-1β,ODI and VAS scores were lower than those before treatment in the observation group and after treatment in the EA group with statistical significances (all P＜0.05).Conclusion:The combination of EA and hydro-acupuncture with sinomenine hydrochloride at Jiaji (EX-B 2) points is effective for low back pain caused by compression fractures in the elderly,and is superior to EA at Jiaji (EX-B 2) points alone.

AIM: To evaluate the effect of probing of lacrimal passage combining injecting of US-produced TobraDex eye ointment for the treatment of chronic dacryocystitis.METHODS: For 127 cases (129 eyes) of chronic dacryocystitis, first the pyoid secretion gathered in the lacrimal sac was dashed out, and some TobraDex was injected in the middle of the lacrimal passage once per day, repeated for several times. The lacrimal passage was probed when the secretion of lacrimal sac disappeared essentially. The lacrimal passage and immit TobraDex eye ointment was used once every two days, repeated for 3-4 times.RESULTS: In 126 cases (128 eyes) the lacrimal passage was dredged. Only one case (1 eye) the youthful patient did not recover for the opening ectopia of lacrimonasal duct.During the 3mo-1a random visit the chronic dacryocystitis did not recrudesce in the cases of lacrimal passage dredging.CONCLUSION: It is simple and safe to use the probing of lacrimal passage combining injecting of US-produced TobraDex eye ointment to treat the chronic dacryocystitis. This method has good curative effects and can keep the normal physiological structure of lacrimal passage. It does not need any expensive medical equipment and cost less, therefore is advisable for patients.

Objective To identify changes in the occurrence of endemic fluorosis in order to provide scientific basis for making countermeasures. Methods Five villages from 14 counties of mild, moderate and severe fluorosis affected areas were selected by stratified cluster sampling every year in the whole province during 2006 - 2010. Water and urinary fluorine were determined by ion selective electrode method(GB/T 8538-1995); dental fluorosis of children 8-12 years old was diagnosed with Dean method; skeletal fluorosis was diagnosed according to "clinical indexing standards of endemic skeletal fluorosis "(GB 16396-1996), between 2006 and 2008, and "clinical diagnosis standard of endemic skeletal fluorosis"(WS 192-2008) between 2009 and 2010. Results A total of 25 diseased villages were surveyed, 14 with water sources changed, covered a resident population of 8005 people, beneficiary population 7154, and accounting for 89.37% of the resident population; not changed villages 11. In accordance with the "State drinking water health standards", in the 14 changed villages the fluoride in drinking water was qualified (≤ 1.20 mg/L), there were 3 schools whose water fluorine content exceeded the standard; among the 11 villages that did not change water sources 7 drinking water samples fluorine content exceeded the standard. Of the 8 to 12 years old children in villages with changed water sources, 363 of them were checked and 142 dental fluorosis were found, the detection rate of dental fluorosis was 39.12% (142/363); in villages with water sources not changed, 303 children were checked, the detection rate of dental fluorosis was 43.89%(133/303). Of sixteen and elder adults in water source changed villages, 6424 people were checked and 403 skeletal fluorosis were found, skeletal fluorosis detection rate was 6.27% (403/6424); 3572 people were checked in not changed villages, the detection rate of skeletal fluorosis was 13.89%(496/3572). In water sources changed areas, geometric mean of urinary fluoride was in the normal reference value(WS/T 256-2005, 1.40 mg/L)or less. Conclusions Endemic fluorosis is decreased in water improved areas, but in unimproved areas the disease is still severe, and control of endemic fluorosis is still an arduous task.

Objective Color doppler ultrasonography of chronic Keshan disease (CKD) was evaluated to provide evidences for clinic diagnosis of the disease. Methods From September to Novermber 2009, according to "Diagnostic criteria of Keshan disease" (GB 17021-1997), 64 cases of CKD were randomly sampled from five Keshan diseased districts in Shandong province, Zoucheng, Sishui, Yishui, Wulian, Jvxian, and Pingyi as patient group. Thirty four healthy volunteers being checked up by Shandong Institute for Endemic Diseases Control and Research were put in control group. All the subjects were examined with Color doppler ultrasonography. The indexes of cardiac structure, left ventricular (LV) systolic function and LV diastolic function were measured.Results Left atrial internal diameter, LV end-diastolic internal diameter, LV end-systolic internal diameter, right ventricular diameter, aorta diameter, right atrial transverse diameter, right atrial long diameter and left ventricle mass of the patient group[(35.38 ± 6.89), (61.57 ± 8.61), (45.39 ± 10.29), (17.22 ± 3.79), (28.69 ± 2.81),(38.00 ± 6.05), (42.68 ± 8.65)mm, (283.22 ± 103.12)g] were higher than that of control group[(26.70 ± 3.27),(45.41 ± 4.93), (26.91 ± 4.35), (13.76 ± 2.27), (24.09 ± 2.89), (31.50 ± 3.32), (35.82 ± 3.14) mm, (156.03 ±39.86)g, t = 6.93, 10.09, 9.98, 4.87, 7.64, 5.81, 4.46, 6.90, all P＜ 0.05]. The LV ejection fraction and fractional shortening of the left ventricular of the patient group[(49.25 ± 14.33)%, (26.11 ± 9.17)%] were lower than that of control group[(73.88 ± 4.04)%, (42.88 ± 3.62)%, t = - 9.79, - 10.22, all P＜ 0.05]. Diffuse hypokinetic motion of the left ventricle reduced in 95% (61/64) of CKD patients, and 5% (3/64) of CKD patients had segmental LV dyskinesia. Seventy five per sent(48/64) of the patients accompanied with mitral regurgitation, and 39% (26/64) of these cases accompanied with tricuspid regurgitation. Meaningful Mitral or tricuspid regurgitation was not found out in control group. Conclusions The CKD patients' bore of atrio-ventricular cavity and LV mass are enlarged, and their motion of ventricle is reduced or partly reduced. They have poor heart function. Mitral regurgitation are more than tricuspid regurgitation. Color doppler Ultrasonography is important in diagnosis of chronic Keshan discase.

OBJECTIVETo explore the protection of high intensity microwave radiation on hypothalamo-pituitary-adrenal axis (HPAA) activity and hippocampal CA1 structure in rats and the protectiveeffect of Qindan Granule (QG) on radiation injured rats.

METHODSTotally 48 Wistar rats were randomlydivided into 8 groups, i.e., the normal control group, post-radiation day 1, 7, and 10 groups, 7 and 10days prevention groups, day 7 and 10 treatment groups, 6 in each group. Rats in prevention groups wererespectively administered with QG liquid (1 mL/100 g, 4. 75 g crude drugs) for 7 days and 10 days bygastrogavage and then microwave radiation. Then preventive effect for radiation injury was statisticallycalculated with the normal control group and the post-radiation day 1 group. Rats in treatment groupswere firstly irradiated, and then administered with QG liquid (1 mL/100 g, 4.75 g crude drugs). Finally preventive effect for radiation injury was statistically calculated with the normal control group, post-radiation day 7 and 10 groups. Contents of corticotrophin releasing hormone (CRH), beta endorphin (beta-EP), adrenocorticotropic hormone (ACTH), and heat shock protein 70 (HSP70) were detected. Morphological changes and structure of hippocampal CA1 region were observed under light microscope.

RESULTSCompared with the normal control group, contents of CRH and beta-EP significantly decreased in each radiation group. Serum contents of ACTH and beta-EP significantly increased in post-radiation day 1 and 7 groups (P < 0.05). Compared with radiation groups, beta-EP content in serum and pituitary significantly increased, and serum ACTH content significantly decreased in prevention groups (P < 0.05). Pituitary contents of CRH and beta-EP significantly increased in prevention groups. Serum contents of ACTH, beta-EP, and HSP70 were significantly lower in day 7 treatment group than post-radiation day 7 group (P < 0.05). Morphological results showed that pyramidal neurons in the hippocampal CA1 region arranged in disorder, with swollen cells, shrunken and condensed nucleus, dark dyeing cytoplasm, unclear structure. Vessels in partial regions were dilated with static blood; tissues were swollen and sparse. In prevention and treatment groups pathological damage of hippocampal CA1 region was obviously attenuated; neurons were arranged more regularly; swollen, pycnotic, or deleted neuron number were decreased; vascular dilatation and congestion was lessened.

CONCLUSIONQG could affect HPAA function and activity of high intensity microwave radiated rats, showing certain preventive and therapeutic effects of microwave radiated rats by adjusting synthesis and release of partial bioactive peptides and hormones in HPAA, improving pathological injury in hippocampal CA1 region.

This study was purposed to analyse the immunophenotypic characteristics of chronic myelomonocytic leukemia (CMML), myelodysplastic syndromes (MDS) and acute monocytic leukemia (AML-M5b) by using multiparameter flow cytometry, and to explore its significance in diagnosis and differential diagnosis. The immunophenotypic characteristics of bone marrow samples from 14 CMML patients, 48 MDS patients, 46 AML-M5b patients and 18 normal persons were analyzed and compared by multiparametric flow cytometry. The results showed that the ratio of monocytes in CMML patients was obviously higher than that in MDS, AML-M5b patients and normal persons (P < 0.05), but there was no statistically significant difference between bone marrow samples of MDS and AML-M5b patients as well as normal persons. The ratio of blast cells in MDS patients was obviously higher than that in normal persons (P < 0.05), but did not show significant difference as compared with CMML patients. The ratio of mature granulocytes in AML-M5b patients was obviously lower than that in CMML and MDS patients as well as normal person bone marrow (P < 0.05). Certain differences of CD45/SSC characteristics in MDS, AML-M5b and CMML patients were found in comparison with normal persons. The abnormal expression of CD2, CD56, and CD14 tailing phenomenon were observed in CMML patients in comparison with bone marrow samples of MDS, AML-M5b and normal persons (P < 0.05). Lack and decrease of CD15 expression in MDS and CMML patients was significant different from AML-M5b and normal persons marrow, abnormal expression rate of CD15 in CMML patients was higher than that in MDS patients (P < 0.05), the CD13/CD11b/CD16 abnormal expression of granulocytes was seen in both CMML and MDS patients, but there was no statistically significant difference between them. Other antigens showed abnormality of varying degrees, but did not have any statistical significance. It is concluded that MDS, CMML and AML-M5b displayed a certain degree of similarity, and also possess their own immunophenotype characteristics. Comprehensive analysis of immunophenotype by multiparameter flow cytometry may be important for differential diagnosis among CMML, MDS and AML-M5b. High percentage of monocytes, abnormal coexpression of CD2, CD56 and CD14 tailing phenomenon, lack or decrease of CD15 as well as abnormal expression of CD13/CD11b/CD16 in granulocytes may play important roles in diagnosis of CMML.
