Objective To observe the clinical efficacy of reinforcing and reducing by acupuncturing at lower He-sea points along and against channel's direction in treating gastroesophageal reflux disease (GERD).Method Sixty-one GERD patients were randomized into a treatment group of 34 cases and a control group of 27 cases. The treatment group was intervened by reinforcing and reducing by acupuncturing at lower He-sea points along and against channel’s direction, while the control group was treated with oral administration of Omeprazole tablets. The two groups were intervened once a day, 4 weeks in total. The clinical efficacies in the two groups were compared based on the symptoms scores before and after the treatment.Result The total effective rate was 97.1% in the treatment group versus 85.2% in the control group, and the difference was statistically significant (P<0.05). The relapse rate 6 months after the treatment was 16.7% in the treatment group versus 50.0% in the control group, and the difference was statistically significant (P<0.05).Conclusion Reinforcing and reducing by acupuncturing at lower He-sea points along and against channel’s direction is an effective approach in treating GERD.
2. Penetrative needling of scalp-points improves neurological function by promoting stem cell proli-feration and activating Shh/Gil1 signaling in intracerebral hemorrhage rats
Acupuncture Research 2020;45(2):93-98
OBJECTIVE: To observe the effect of penetrative needling from "Baihui" (GV20) to "Qubin" (GB7) on neural stem cell proliferation and sonic hedgehog (Shh) signaling in subventricular zone (SVZ) in intracerebral hemorrhage (ICH) rats so as to explore its mechanisms underlying improvement of ischemic injury of brain. METHODS: Male SD rats were randomly divided into blank control, model, acupuncture and agonist (Purmorphamine, an activator of Shh signaling pathway) groups (n=18 in each group, 6 for H.E. stain, 6 for examining neuronal cell proliferation, and 6 for immunohistochemistry). The ICH model was established by injecting autogenous blood (50 µL) into the right caudate nucleus. The neurological defect was scored with refe-rence to Bederson's method. Penetrative needling from GV20 to GB7 was performed by manipulating the needle for 6 min (repeated 3 times in 30 min), once daily for 7 days. Intraperitoneal injection of Purmorphamine (1 mg/mL, 1 mg/kg) was performed, once daily for 7 days. Histopathological changes of the hemorrhagic penumbra region were observed under microscope after H.E. stain, the newborn neural stem cell proliferation (BrdU+/Nestin+ double labeled cells) in the SVZ was observed by immunofluorescence after intraperitoneal injection of BrdU (50 mg/kg), and the expression of Shh and glioma-associated hemolog-1 (Gli1) detected by immunohistochemistry. RESULTS: After modeling, the neurological score and expression levels of Shh and Gil1 proteins were significantly increased in the model group relevant to the blank control group (P<0.001). Following the interventions, the neurological score was evidently decreased (P<0.05), while the number of BrdU+/Nestin+ double labeled cells and the expression levels of Shh and Gil1 proteins were significantly increased in both acupuncture and agonist groups in comparison with the model group (P<0.001). No significant differences were found between the acupuncture and agonist groups in down-regulating the neurological score and in up-regulating the number of BrdU+/Nestin+ double labeled cells and the expression of Shh and Gil1 proteins (P>0.05). Outcomes of H.E. stain showed obvious edema, disordered arrangement of cells, infiltration of inflammatory cells and red blood cells with glial cell hyperplasia around the hematoma area in the model group, which was relatively milder in both acupuncture and agonist groups such as in basic disappearance of edema and inflammatory reaction. CONCLUSION: Penetrative needling from GV20 to GB7 can obviously improve neurological function in ICH rats, which is related to its effects in activating Shh/Gil1 signaling and in further promoting neural stem cell proliferation in the SVZ region.

Osteoporosis and Sarcopenia 2024;10(2):60-65
Objectives:
Type 2 diabetes mellitus (T2DM) shares a complex relationship with bone metabolism and few studies investigated the effect of impaired bone health on the risk of T2DM. This study was conducted to investigate the association between hip fractures and the risk of incident T2DM.
Methods:
This is a retrospective cohort study using data from the real-world hip fracture cohort. Hong Kong Chinese patients aged ≥ 65 years without T2DM who were admitted to public hospitals due to a fall between 2008 and 2015 were included in the study. Patients who sustained falls with and without hip fractures were matched by propensity score (PS) at a 1:1 ratio. Competing risk regression was used to evaluate the association between hip fracture and incident T2DM, with death being the competing event.
Results:
A total of 23,314 hip fracture cases were matched to 23,314 controls. The median follow-up time was 5.09 years. The incidence rate of T2DM was 11.947 and 14.505 per 1000 person-years for the hip fracture and control group respectively. After accounting for the competing risk of death, the hip fracture group had a significantly lower risk of developing T2DM (HR: 0.771, 95% CI: 0.719–0.827). Similar results were observed in all subgroups after stratification by age and sex.
Conclusions
Hip fracture was found to be associated with a reduced risk of T2DM. These findings provide insight into the topic of bone and glucose metabolism and prompt further research in evaluating the role of bone health in the management of T2DM.

INTRODUCTIONThis study aimed to report the injury or disease patterns, challenges, key observations, and recommendations by the Singapore Armed Forces (SAF) team that embarked on an Humanitarian Assistance and Disaster Relief (HADR) mission in the aftermath of the April 2015 Nepal earthquake.
METHODSThe SAF medical team that provided HADR assistance to Nepal consisted of personnel from the SAF, Singapore¢s Ministry of Health and the Royal Brunei Armed Forces. Upon arrival in Kathmandu, Nepal, the SAF medical team was assigned to the Gokarna district by the local health authorities. In addition to providing primary healthcare, the medical facility was equipped to perform resuscitation and minor procedures. We also assembled mobile medical teams (MMTs) that travelled to various remote areas of the country to deliver medical aid.
RESULTSA total of 3,014 patients were managed by the SAF medical team. Of these patients, 1,286 (42.7%) were men. 574 (19.0%) patients sustained earthquake-related injuries or illnesses, while 2,440 (81.0%) sustained non-earthquake-related injuries or illnesses. The team treated a total of 447 (77.9%) adults and 127 (22.1%) paediatric patients with earthquake-related injuries or illnesses. A significant number of patients developed exacerbations of underlying medical conditions. 2,161 (71.7%) patients were treated in our main facility in Gokarna, while 853 patients (28.3%) were treated by our MMTs.
CONCLUSIONThe ability to transport healthcare personnel and essential medical equipment within a short time allowed the SAF medical team to provide crucial medical care in the aftermath of the 2015 Nepal earthquake.

OBJECTIVE:
To observe the effect of acupuncture at "Baihui" (GV 20) through "Qubin" (GB 7) on NLRP3 inflammatory corpuscle in rats with intracerebral hemorrhage (ICH), and to explore the action mechanism of acupuncture on promoting the recovery of neural function in rats with ICH.
METHODS:
Forty SPF six-week-old male SD rats were randomly divided into a sham operation group, a model group, a non-acupoint group and an acupuncture group, 10 rats in each group. The rats in the model group, non-acupoint group and acupuncture group were intervened with autologous blood injection to prepare ICH model, while the rats in the sham operation group were only intervened with operation but not injection with autologous blood. About 3 hours after the establishment of the model, the rats in the acupuncture group were intervened with acupuncture at "Baihui" (GV 20) through "Qubin" (GB 7), once every 12 hours, for 7 days; the rats in the non-acupoint group were intervened with acupuncture at the non-acupoint [parallel to the "Baihui" (GV 20), 1 cm next to the midline] on the affected side, and other treatment was the same as the acupuncture group. At the end of the intervention, the composite nerve function score of each group was evaluated; the histomorphology of the hemorrhage penumbra was observed by HE staining; the expression of NLRP3 inflammatory corpuscle in the brain was detected by immunohistochemistry; the relative protein expression levels of NLRP3, interleukin-1β (IL-1β) and interleukin-18 (IL-18) in brain were detected by the method of Western blot.
RESULTS:
Seven days into intervention, compared with the sham operation group, each item score and total score of composite nerve function in the model group were significantly reduced (<0.01, <0.05). There was edema and karyopyknosis in brain neuron as well as necrocytosis and inflammatory cell infiltration in the model group. Compared with the model group and the non-acupoint group, the total score of composite nerve function and the scores of symmetrical movement of limbs (LS) and proprioception of tentacles (VP) in the acupuncture group were increased (<0.01, <0.05), and the cell necrosis and inflammatory cell infiltration were relieved. Compared with the sham operation group, NLRP3 inflammatory corpuscle expression and the relative protein expression levels of NLRP3, IL-1β and IL-18 in brain tissue in the model group were increased (<0.01); compared with the model group and the non-acupoint group, NLRP3 inflammatory corpuscle expression and the relative protein expression levels of NLRP3, IL-1β and IL-18 in brain tissue in the acupuncture group were reduced (<0.01).
CONCLUSION
Acupuncture at "Baihui" (GV 20) through "Qubin" (GB 7) could downregulate the expression of NLRP3, IL-1β and IL-18 in the brain tissue of ICH rats, inhibit the inflammatory response, and promote the recovery of neural function.

OBJECTIVETo investigate the potential efficacy of panaxadiol saponins component (PDS-C), a biologically active fraction isolated from total ginsenosides, to reverse chemotherapy-induced myelosuppression and pancytopenia caused by cyclophamide (CTX).
METHODSMice with myelosuppression induced by CTX were treated with PDS-C at a low- (20 mg/kg), moderate- (40 mg/kg), or high-dose (80 mg/kg) for 7 consecutive days. The level of peripheral white blood cell (WBC), neutrophil (NEU) and platelet (PLT) were measured, the histopathology and colony formation were observed, the protein kinase and transcription factors in hematopoietic cells were determined by immunohistochemical staining and Western blot.
RESULTSIn response to PDS-C therapy, the peripheral WBC, NEU and PLT counts of CTX-induced myelosuppressed mice were significantly increased in a dose-dependent manner. Similarly, bone marrow histopathology examination showed reversal of CTX-induced myelosuppression with increase in overall bone marrow cellularity and the number of hematopoietic cells (P<0.01). PDS-C also promoted proliferation of granulocytic and megakaryocyte progenitor cells in CTX-treated mice, as evidenced by significantly increase in colony formation units-granulocytes/monocytes and -megakaryocytes (P<0.01). The enhancement of hematopoiesis by PDS-C appears to be mediated by an intracellular signaling pathway, this was evidenced by the up-regulation of phosphorylated mitogen-activated protein kinase (p-MEK) and extracellular signal-regulated kinases (p-ERK), and receptor tyrosine kinase (C-kit) and globin transcription factor 1 (GATA-1) in hematopoietic cells of CTX-treated mice (P<0.05).
CONCLUSIONSPDS-C possesses hematopoietic growth factor-like activities that promote proliferation and also possibly differentiation of hematopoietic progenitor cells in myelosuppressed mice, probably mediated by a mechanism involving MEK and ERK protein kinases, and C-kit and GATA-1 transcription factors. PDS-C may potentially be a novel treatment of myelosuppression and pancytopenia caused by chemotherapy.

AIM:
To establish the Spectrum-Effect integrated fingerprint of Polygonum cuspidatum to evaluate the quality of P. cuspidatum.
METHODS:
An on-line HPLC-DAD-flow injection chemiluminescence (FICL) method was developed to investigate the quality of P. cuspidatum from different habitats based on the established Spectrum-Effect integrated fingerprint.
RESULTS:
Nineteen batches of samples of P. cuspidatum were evaluated for the similarity of their chromatographic and free radical scavenging fingerprints, and the results compared. Main antioxidants were estimated by regression analysis between peak areas of thirteen compounds and their activities. Some active compounds were identified by HPLC-ESI-MS.
CONSULSIONS
The results indicated that main antioxidants in P. cuspidatum could be rapidly screened by the established Spectrum-Effect integrated fingerprint based on on-line HPLC-DAD-FICL, and would be more efficient and objective method to evaluate the quality of P. cuspidatum.
